I'm currently TAD overseas (U.S. Navy), so i've been stuck on the computer researching which products i want to use, and what intentions i have for my FC.

Im going with a 13B-RE.. i have most of the info on what i need to do.. such as motor mounts, wiring (going haltech).. etc.. I will be rebuilding myself using most likely the RA kit.. but as the topic is brought up again, should i go 2mm, or 3mm? Most have said to stay with 2mm since i have a goal of 400RWHP @ 15psi. But there are other's who like to differ.. So far im sticking with 2mm RA seals. Anyone have info to change my mind? BTW i will be doing a large Street port to the motor.

So the motor is pretty much thought up, besides other misc things i.e. stationary gears hardened, high oil pressure reg/pump.. Does anyone have any info on the ceramic coating of rotors? I understand rotorsportsracing offers this done..

I will be premixing... Im actually kind of interested in the PVC industries MOP adapter plate -> allows you to run an external tank.. anyone have any experiences with it? mazdatrix sells this for ~$80 i think

So anyway.. i'm stuck on the turbo setup.. I want to go with a kit, but at the same time, im a DIY guy also.. I've assisted in a 13BT rebuild, done several motor swaps (4g63, 4age, 13b,13bt, d16) So i have the tools and resources, and i also work on helicopters... so i know a little about mechanics .. So i don't really know about getting a kit, also because most kits include a DP.. and i'm not getting an FC kit, because i am hanging this turbo on the RE. an FD DP will be worthless to me.. i will need to get it custom done.. So far i've been looking at the 60-1.. GT35/40 <-- $$!! I just need 380-400RWHP.. Reliably. This is not a daily driver (have the faithful N/A for to and from work) .. Also i do autocross about once a month (if SCCA has a place to locally run it, im there).. So spool up time will be somewhat of an issue.. But the main focus in my eyes is reliablity... I really don't care to blow apart a freshly rebuilt motor.

There will be a FMIC on this car.. Looking at the greddy kit, but again, it's for the FC.. is it worth it to go custom?

I'd like to use a tubular manifold as well, but i'm having difficulties locating a decent manifold for a good price.. any referals?

I have a local haltech tuner to assist me.. He has a wideband as well.. although i am considering purchasing my own.

Other fuel mods will be done, (injectors, fuel pump, regulator, etc..)
Clutch and drivetrain will be beefed up with an aftermarket flywheel and clutch (ACT).
Suspension a brakes aswell...

Any suggestions are greatly appreciated.. (i am going nuts over here trying to imagine what a 400HP FC will be like!)

Thanks,
Justin

 

If it is really for autocross you will be hard pressed to find a better turbo than the 35R .82 exhaust it spools like a V8 for the most part, and will provide you with around 360whp@15lbs depending on how everything else is that gets you right to your 400hp mark. 35R's are not that expensive I can do them for around $1300 IF your looking for more topend later you could then switch to a 1.06 that will still spool to 15lbs by 3300-600rpms depending on port and tune. I'm not saying this is your only choice just one that is very hard to beat under autocross circumstances.

 

Sounds like Sean's solution is a plug and play option meeting your hp needs. The Apexi turbo kit is fast spooling too but costs more and is not water cooled.

Fabbing your own is cool but if you can get a well made kit with a tubular mani, plumbing, wg, etc that works it may get you out from under the hood and in the driver's seat sooner. I assume Sean can hook you up with a kit for the 2gen.

 

If you are concerned about spool time, stick with the twins. Get some 99 spec twins, they work great for auto cross. The smaller 35R simply isn't worth the cost associated with going single. It will clean up the engine bay and make problems easier to diagnose, but that's about it. You won't make any more power than the stock twins with the smaller one. Other options include a T04E/B or the smaller RX6.

 

It's not about making more power with the smaller one, it's about not ringing the **** out of the turbo to make the power. He already has the associated costs as well I thought he said, oh well, If you guys haven't been in a 35R with the .82 you wouldn't believe the response it as good as it gets. I would also say stick with the 2mm seals, It's all I've ever run on any of my cars. It should get you where you want to be and if you want room to grow you can still go to a 1.06

 

Thanks for the responses....

Yeah, im ditching the twins.. it's too much of a mess, and since the RE is going into an FC, i don't want to deal with any clearance issues.
Some people are mentioning to go with a hybrid, and i've thought about it.. I go back and forth weekly changing my mind.. I'd like to keep the cost level down, but in the automotive world, cheaper cost = cheaper product. Like i said, i'd like to not blow this thing apart (knock on wood)..

I've been searching constantly every day and night trying to find a good tubular manifold to hang on the RE, that will fit in the FC's engine bay. I almost want to make my own, although i have poor welding skills (that's where friends with good welding skills + beer comes in hand), although i have seen some very nice work on the forums. I guess i just have to search more for the manifold i like, and someone who makes it.

I like the GT35R.. but im not sure if it will completely fit my needs.. I hear nothing but good about them though.. Will this turbo be good for lower boost as well? I want to setup the controller and tune for two different boost levels, such as 7 PSI, and 15 PSI..

As far as wastegates, what size and brand do most people run? I'm new to the single turbo world...

Oil lines and coolant lines... what types of lines are reccomended, and what would i need (fittings, adapters.. etc..)

I will continue to search, (it's probably right smack dab in front of me)

Thanks for the help.

I ran the 1.06 GT35R and I thought it spooled nearly as well as the twins. I bet the .82 hot side would be instant power. But would drop off up top pretty fast is my guess.
