A Look Back at the TEIN S15

Recently saw on facebook that Import Tuner magazine is running a contest to see what the next cover car should be. One of the front runners is a white S15. It reminded me of when the TEIN S15 was on the cover of Import Tuner.

March 2006 issue. Click HERE to read the article.

Back in 2005 when drifting and time attack were blossoming in the US, TEIN decided to build a monstrous demo car. The purpose was to build a single car that could compete in select drift and time attack events. Prior to this decision we were sponsoring or borrowing cars to compete under the TEIN name.

One of our engineers who had some fabrication and rally racing experience was put in charge of the project. I obtained parts and helped with final assembly when I was not working on our 2006 Civic Si Coupe (also debuted at the 2005 SEMA show). I do not think our bay door closed for an entire month. Some of us worked, ate and even slept at the office to get the two cars finished.

This picture was probably taken at 2 or 3am a few nights before the cars had to leave for Vegas.

In the end the S15 was completed just in time to display at SEMA.

Under the hood sat at RD28DETT which was pushed back over 10″ to improve weight distribution. The motor was fully built from top to bottom with HKS parts and produced an easy 600HP and 550ft-lbs of torque.

There were tons of custom parts including Ikeya Formula arms to widen the track, tubed front and rear fender wells, v-mount rad/ intercooler, crazy jungle-gym like cage, gussets everywhere, this car could have probably launched off a cliff and nothing would happen.

Ikeya custom arms, custom composite driveshaft, ARC transmission and Diff coolers, Fujitsubo custom flat side exit exhaust.

Custom fuel surge tank, dual Bosch fuel pumps, ARC pumps for the trans. and diff., halon nozzle, plus last minute fabricated aluminum wing supports.

DEFI Super Sports Cluster, dual EDFC, floor mounted pedal assembly. Not much room since the trans. tunnel was remade to fit the OS Giken 6-speed sequential and because the engine was so far back.

Over the next couple of years the car shipped back and forth from Japan. While in Japan it displayed at Tokyo Auto Salon, and had work done by MCR.

A quiet day at Streets of Willow for the car’s first shakedown. It was pretty awesome to see the car run for the first time. 

In the end we ran the car twice at Super Lap Battle but the results were nothing special. Not enough testing and tuning to really get it properly dialed-in. Our engineers re-focused on product development instead of trying to be a race team, which we are not.

This car always reminds me building cars is about the right combination of parts and proper testing/ tuning. The TEIN S15 was constructed with a plan, had high-end quality parts and tons of fabrication but in the end maybe the combination just wasn’t right. Hopefully we will see the car re-emerge one day.

 

 

Cyber EVO-LUTION

World Time Attack is on my mind. Excited to see if the Cyber Evo can retain the title of fastest time attack car in the world. Other blogs and online news sources have been posting images and information on some of the contenders and I have been reading it all. It looks like the competition will be fierce this year.

Personally I have to cheer for the Cyber EVO. Besides the fact that it runs TEIN coilovers it has so much history. I can remember watching Option video of Nomuken visiting Dr. Takizawa’s office to check out the car. At the time and still now, I think it is awesome that a privateer can compete against manufacturers, well-known tuners and race teams.

Here are some pics I found of the car over the years. You can see the EVOLUTION of the car especially in the aero department.

A visit to the dentist’s office.

 

2008 – From the C-West aero to full Voltex

2009 – More development

2010 – At WTAC

2011 – Testing at Fuji in preparation for WATC 2011.

In my book the Cyber EVO is still the best looking Time Attack EVO of all time.

However the technical advancements in the competitors is amazing. Sierra Sierra has made improvements throughout the car which Eric Hsu explains on MotoIQ. There are new cars from Australia with some CRAZY aero mods as well.

I look forward to seeing all the event coverage.

GO CYBER EVO !!!!!!!

Stephan Verdier at X Games 17

This weekend Stephan Verdier will be driving his STi in X Games 17 in Rally and Rallycross competition.

Tune in to ESPN or ESPN3.com on Saturday from 1-3PM PST for Rally and 2-4PM PST on Sunday for RallyCross action.

Stephan’s car has undergone changes in preparation for X Games which includes a brand new Tarmac spec Gr.N damper. Our in-house engineer, Katsuma Nakai, has been on-hand to help setup and tune the suspension for the new X-Games street course. Stephan should be a force to be reckoned with. He has been  considered an underdog all year long as he is one of a few teams/ drivers which is not factory backed (big budget). Yet his Crawford powered STi can compete right alongside the factory Fords, Subarus and Hyundais. Stephan has been competing all year in the Global Rally Cross and currently sits 4th in the overall standings behind Foust, Gronholm and Jernberg.

Root for Stephan this weekend, we will be.

A little over a month ago Stephan drove the Zenkai Motorsports STi at Pikes Peak Hillclimb. He is featured in a video just released by Motul. The Zenkai STI is powered by a Crawford built motor and utilizes Super Racing coilovers.

Stephan unfortunately crashed about 2/3 rds up the hill. The heavy winds and road surface conditions change by the minute making Pikes Peak one of the most dangerous hill climbs in the world. We are glad Stephan walked away unscathed.

FINAL ROUND of 2011 Rally America

This past weekend was the final round (Rd. 6) of the 2011 Rally America series. TEIN sponsored Sparco Rally xD made the trip out to Maine for the New England Forest Rally. Andrew-Comrie Picard and Jeremy Wimpey returned as driver/ co-driver. The winning combo last drove the car at round 4 in Oregon to the 2WD class win.

At NEFR the newly improved xD faced a plethora of Ford Fiestas including 2010 2WD Chris Duplessis (who drove the xD last year), 2009 2WD Champion Dillon Van Way in another Fiesta and 2011 2WD Champion Wyatt Knox in a MazdaSpeed 3.

Since Oregon the xD has undergone major modifications mainly in the power department. Greddy tore down the motor and installed Carrillo forged rods and pistons to beef up the 1.8L. The fuel system was upgraded as well which netted a significant power gain. The 1.8L Scion xD now produces 200 WHP, up 35 WHP from the last outing. Not big by HP number but if you look at percentages that is a big difference.

Greddy engineers working on the 2ZR-FE.

Carrillo components help beef up the short block. Power is still left at a conservative 200WHP.

The HG suspension worked perfectly over the rough terrain and various sized jumps.

NEFR was a real test for the car and newly modified engine as it has some long stages, three 16 mile stages and one 19 mile stage. The crew tells me the motor ran flawlessly but there were other issues to deal with at every service. Loss of 3rd gear, a slipping clutch, damaged exhaust system, cracked wheel, punctured tires…

The crew working hard during service to inspect and repair the xD.

Some of the chassis modifications that Design Craft made prior to NEFR also paid off. This tubular brace was added to the underbelly of the car for added reinforcement against all the offroad abuse. Even with this, the oil pan took a hit. Without this who knows what would have happened to the oil pan.

At the end of the 2 day rally, the Rally xD finished second in class and sixth overall. OVERALL. Meaning against 4WD turbo STIs, EVOs and WRXs.

Sunday was a Funday

This is not one of our normal posts but these are some of the staff at TEIN USA – West.

The staff here at TEIN USA try to have a Summer BBQ at least once a year. Yesterday was our out of the office funday. There was grilling, eating, 3 on 3 basketball, kids running around and more eating.

 

Our Operations asst. manager, Paul, hosted and served as grill master.

Our BBQ included current and ex-staff members. I think everyone was most impressed by the diversity in food which included:
Korean short ribs, Ribeye steak, Pork Belly, Asian style BBQ chicken, Portuguese sausage, Ceviche, 2 kinds of Enchiladas, assorted rice balls, Chicken Adobo, Lumpia, Pancit, mixed green salad, Japanese cucumber salad, homemade guacamole, spinach Empanadas, baked donuts, assorted fresh fruits, and multi-layer cake.

 

Air Marc. He’s from Hawaii so he does everything in slippers.

Brian, also with slippers. It was like 90 degrees so flipflops were the footwear of choice.

Our accountant, Hirayoshi playing some catch. Both these guys are from Japan where American football is not a popular sport. I think this was the first time Hirayoshi had thrown a football.

The boss and his wife playing some catch.

The kids even got in on the sports. Jaydean here is taking it in for a touchdown!

One of our operations staff doubles as a Yokohama Globe Trotter.

Our accounting assistant, Mirelle, putting it up and in.

Hirayoshi playing some basketball. He said the last time he played was about 20 yrs ago. He is actually a good surfer and downhill mountain biker.

Our engineer, TK, taking our accountant off the dribble.

Taking a break and enjoying the day.

Good times were had by all.

Coilover Spring Swap

I have not really touched my EVO since my last track day back in May. The car felt the same, stable. Maybe too stable, meaning a tendency to understeer. I tried to compensate by aggressive trail braking and almost jerking the wheel to get weight transfer but the wide tires, wide body and aggressive aero keep the car super planted.

I have been meaning to try some different spring rates or R-comp tires for, hmmm… about the last 2 years. Spring rates and tires are VERY related. Higher grip tire = higher spring rates and vice versa. I am currently using 14kg front and 12kg rear springs plus slightly larger sway bars for front and rear. Over the past couple of years I have run Hankook RS2, Azenis RT-615 (non K), Continental CSC3 and Continental ExtremeContact DW. All street tires with similar performance. In my mind I thought my next purchase would always be a set of R-Compounds or extreme performance summer tire like an Advan Neova. But I just never seem to get there. I always end up buying something else, like my Voltex street front bumper, HKS V-Pro (which is sitting on a shelf in the garage), new DEFI Advance ZD, etc….

It FINALLY dawned on me that I should stop being lazy and just switch the springs to better suit the tires I always seem to use. A cheaper and more practice solution than spending $1300+ on tires. So last night I bought some softer springs (MSRP $120 per pair) and installed them. I went for a 2kg spring rate change. Now I have 12kg front and 10kg rear. The spring swap went relatively quickly. Depending on the damper we recommend a damper revalve if the spring rate is changed by +/- 2kg (for BASIC and Street Basis +/- 1kg since the damper is not damping force adjustable).

New 10kg springs for the rear. The 12kg originally on the rear will go to the front of the car since my setup uses SQ type springs for front and rear.

Here is a little useful information: This is how you can check what TEIN springs you have. The number printed on the spring is the individual spring part number. The part number listed on our website, catalog, etc…is a kit part number. So these springs are from kit part number SQ100-01175. The “SQ” designates a type of spring which is in this case is a standard straight spring, 65mm ID, 175mm free length.  The “100” after SQ is for the spring rate, 10kg. ex. 050 = 5kg. 140 = 14kg. “01175” is for the free length. Just pay attention to the last three digits which is the length. ex. 01200 = 200mm. 01150 = 150mm.

On the actual spring the part number is “Q100-GOC”. “Q” represents spring type, 65mm ID, 175mm free length. “100” is spring rate = 10kg. “QOC” is the LOT/ batch in which this spring was made.

First, I measured wheel center to fender height before starting. Maintaining the ride height will mean I will not need to do an alignment.

Not using the lift for this. (Getting lowered cars with aero parts on a normal lift is a pain. Got to drive up on ramps, use wood, adjust the risers on the arms, etc…) Simple jack and stands is quicker for something like this.

Started with the rear since my rear springs will go onto the front of my car. Super easy since my interior trunk panels are not installed.

I use Simple Green and a rag to clean off the coilovers. Then I inspect all components of the coilovers for damage, etc… I made a small adjustment in spring seat height to maintain ride height with the new softer spring rate. If the spring seat or damper length is not adjusted, the ride height will be lower due to the softer spring rate (softer spring will compress more = lower ride height).

Now for the front. Cool trick on the front of the EVO 8/9 and maybe older gens is that the front spring can be swapped without removing the damper. This means the alignment is not affected since you never even loosen the upright (hub bracket) bolts. Plus this saves LOTS of time.

Just remove the top nut then top mount. Then the spring can be removed and swapped through the strut tower. Depending on what type of tower bar you have, the bar may need to come off. My aluminum Carbing 3-pt. bar does not need to be removed as it has an open top design (quick spring change compatible and EDFC compatible).

Removed my EDFC motor first. Then I slowly removed the top nut with a 21mm deep socket. (Impact Guns need to be used with care as internal damper damage may occur if used excessively).

Used my leg to push the hub down and got the piston shaft out of the top mount. I just angled the damper in the fender well so it was out of the way while I removed the upper mount.

After removing the EDFC strut kit parts and upper spring seat the main spring comes right out.

After swapping the spring I re-installed the top mount then used a floor jack to lift the damper back up into the top mount. Jack was placed under the under arm and I slowly raised it up.  Re-tightened everything and re-installed the EDFC motor. Lastly I adjusted my shell case length by a few mm to maintain the original ride height.

I use a paint pen to mark the seat locks so I will know if they get loose. Be sure to torque the lower bracket lock.

Car back on the ground. I moved the car around to settle everything. Lastly I re-measured the wheel center to fender to ensure my ride height/ alignment has not changed.

All done. Now it is time for a test drive and a little fun. Hope to be testing the new spring rates next month at ButtonWillow Raceway.

Pikes Peak Hillclimb is around the corner

The 2011 Pikes Peak Hillclimb is just a little over a week away. There are a few big teams going out to the 89th running to break the unlimited class record. You might have already seen a bunch of the testing videos of Rhys Millen, Dallenbach Racing, Dancia Duster, etc… if not you might want to search on youtube. Some amazingly fast cars.

I love the unlimited cars for their technology and sheer craziness but I what is really interesting to me are cars that are modified production vehicle. Zenkai Motorsports’ STi is one of those cars. It has previously competed in Time Attack and Gymkhana. For PPHC it will be driven by Stephan Verdier. Stephan will actually be pulling double duty. Competing in Global Rallycross on June 17 and 18th, then attacking the mountain on June 24th.

Check out the serious front splitter. Not unusual for a Hill Climb car.

For the Rallycross Stephan will be behind the wheel of his STi equipped with TEIN Gr.N dampers. The following weekend he will be behind the wheel of the Zenkai STi which is has TEIN Super Racing dampers.

We wish Stephan the best of luck in both events.

Here are some videos from last year.

New Product STREET BASIS DAMPER

TEIN is proud to release the new Street Basis damper to North American consumers. Street Basis Damper is the evolution of the popular BASIC coilover model. It incorporates new internal and external components, newly developed coatings and new manufacturing processes. The end result is a ride height adjustable coilover which is less expensive and more durable. MSRP starts at $700.

 

PRODUCT FEATURES

NEW Internal Components

TEIN engineers have spent many hours developing new seals and internal components to improve durability and product life. This was one of our major goals for the new model.

“ZT” Corrosion Resistant Coating

Newly developed “ZT” coating for improved durability and hassle-free ride height adjustment. TEIN developed this coating in-house after stringent test and analysis procedures. Our engineers tested different coats, application methods, cleaning processes, etc… in our own brine salt water testing machine which simulates heavy solvents/ road salts used in cold weather climates.

Non-welded Adjustment Tube

Slip-fit threaded adjustment tube. Allows for damper body and threaded sleeve to be thoroughly coated for rust/ corrosion protection.

The slip-fit allows a more thorough coating on the threaded section as well as powder coated damper body.

Revised Spring Seat and Thrust Washer

Revised Aluminum Spring Seat and Delrin Thrust Washer are light weight and durable. This combination allows for smooth ride height adjustment. The new spring seats have a larger contact surface area and eliminate the need for a rubber spring seat.
