Ask and you shall receive...

So its coming down to the wire as Rd 1 of FD is approaching quickly but more importantly are the test days we have scheduled prior to our debut. There's still a lot on the "to due" list but everything is right on schedule and we'll be ready for Long Beach.

Many of you have been anticipating details on the drivetrain and I'll be happy to shed some light on it. Some things will be finalized soon but here's what I can say. As mentioned in prior posts, transmission is G-Force GSR 4 speed. Diff is from OS Giken, sorry but I can't remember the exact spec right now. The suspension is KW prototypes based off their competition 3A model. ECU we'll be using is the Cosworth ECPro to compliment the Cosworth CS600 series long block along with ECPro Dash. As for cooling set up, we went with approximately 2.5 inch thick radiator and of course a GReddy Spec R type 24 intercooler. We'll also be installing a GReddy 13 row oil cooler as well. Did I mention the Cosworth dry sump system?

I'll have more photos later but hopefully these calm the nerves for now.

Here's how the car looked like last week


This is what the car looks like right now. Plumbing will be a different set up from when the car ran with in early testing so it will be re-done and completed this week. Notice the set up is now a V-Mount!

 

Thanks for updates, engine and box looks stunning!
I guess every 86 based drift car will use dry sump, especially those who will swap inline or v-type engines.
Do you modify OEM hubs or swap some other subaru stuff with new arms? front/rear? or its a secret for now?
On another note - are you working on any 86 specific upgrades apart from the FD car? Or there is no time for such projects until Long Beach is completed?
Thank you again, this is very entertaining!

 

In regards to dry sump, every race car in general should have one whether its an 86, drift car or not. It will assure the engine will not experience oil starvation during g-force such as acceleration, braking and cornering or for our purposes, getting sideways. You also eliminate the stock oil pan with a flush cover so it allows you to mount the motor lower in the vehicle thus lowering the center of gravity. Not that it needs to be lowered any more in the FRS since it is already low from the factory.

Its no secret that every competition drift car has some sort of modification done to the hub/knuckle area. The hubs are still stock and will be till spare parts can be sourced. We already know how we want to modify the knuckle but we don't want to run the risk of machine shop making a mistake, lost during shipping, etc and not being able to complete the build. Maybe spare parts aren't available yet cause they're all being used for production vehicles right now? Who knows. We just have to work with what we have for now.

We haven't had much time to dedicate on aftermarket parts for production vehicle but we managed to squeeze in a lil something something. We prototyped 3 different exhaust and a few other goods which should be timed with the release of the vehicle if all goes well. We'll leave this discussion for another place.

 

Ken stopped by today to check progress on his car again. I can't tell you how excited he is to start drifting this car! He was actually wrenching a few bolts earlier helping out one of our technicians, lol.



Turbo FR-S

 

Guess what's going down today at GReddy? A little fine tuning before we go testing. Preparations for Long Beach are looking good.

If only you guys can hear her scream!

 

Someone does have a video, right?

 

defly watching this thread :D

 

so sad to see this. I was REALLY hoping for a build on the current motor and or at least have subaru/ trd or beams or perrin or something build the motor. but hrmmm....


also interesting to use a 4 speed.

neat. can't wait to see this on the track though.

 

We aren't trying to disappoint by neglecting the FA20 motor. We've been in a crunch for time since day one and with 2 guys dedicated to building this car, the chassis has been the main focus. Properly building the car to FD spec and making one-off custom parts is time consuming labor. Simply put we don't have enough time to test and develop the FA20 to be competitive by the season opener, especially while the chassis is still being assembled. If we we're to build the FA20 motor, which we will once FD gets under way, all internal components will be removed, assessed, re-engineered, tested and repeated till the product meets the qualification we set to achieve. I'm sure you know this doesn't happen over night and is a process that takes months and is years in the making. That's why we're using the Cosworth EJ motor which has been developed and tested through WRC programs to get us going for the season. From here, we can collect data to be incorporated into the FA20 once the development gets started. Plus there's a lot of weight on our shoulders so we needed a reliable power plant to meet those expectations. There's a lot of other reasons too but I'll keep this explanation short.

So the car is back from body and wrap and is nearly complete. Many are curious for hi-res detailed photos of the car, especially the engine bay. Unfortunately we aren't allowed to release any shots as Scion Racing will be debuting them in 2 weeks. We'll be putting on the finishing touches and then it's off for some pre-season testing.

Gram Lights...yum

Here's a quick update for you all....

So we're 15 days out till our debut and we're both excited and anxious as we complete our initial build. So yesterday we scheduled a private tech inspection and the vehicle passed with flying colors! The GReddy Drift FR-S is Formula D legal! Preparations are coming along great as we have test dates scheduled to shakedown the car and dial it in. We should be pretty good for Long Beach but in this sport, anything can happen.

So remember the spy shots of the FR-S at Laguna Seca from December '11?
Check out the video below from that day.

 

Very Nice...

Can't wait till season starts and I see this baby in Atlanta.

 

agreed very nice

 

HOW did the Greddy FRS run today at testing.

 

ANY PICTURE'S!!!!!

 

This thread is full of win!

 

+1 ^^^^^^^^^^^^^^^^^

 

So we were out doing more testing yesterday and overall it was a good day. We learned more about the car and Ken is settling into his new office nicely. We tried out different car set up as Ken was doing practice runs and we collected good data we can use for the future.

I was busy but the guys over at DTA were able to get some nice shots. Check it out!

Here's a video of NAIAS and the drift FRS reveal from Ken's perspective. It happened a few months ago but the video is fresh from the editing room.
