Ok, I have a WRX, but I am trying to reach 400 WHP with a race tune. I am buying an AXIS sti shortblock, and a GT35R kit, not sure which to go with. Any suggestions there?
Also, I have the JUN cam kit to build up the WRX heads. Of course I am worried about the Tranny, i have an ACT clutch, but thats all. I just bought a Magnus sheetmetal intake, PE timing belt, APS DR725 fmic, and all Unorthodox pulleys. Any help on which injectors or if I should just upgrade my pinks would be appreciated. Is a safe 400 WHP possible with WRX heads? Also, I am using the UTEC, GT spec headers, Magnaflow Ti exhaust.

i hope this isn't your daily driver. goodbye reliability!

You can make 400whp on pump pretty easy with that set-up. The kingpin kit is made to work with APS fmic's, and will easily do 400whp on pumpgas. With all those mods low to mid 5's is pretty easy to reach.

The tranny is another story, i would start looking into 6speeds, or mabey a dog box.

You are going to need a decent amount of fuel. 800's are probally going still be cutting it close.

I would go back to stock manifolds.

i hope this isn't your daily driver. goodbye reliability!

Hmm my daily driver has a built motor, and a 35r kit. ;)

wow, nice advice!

9vapors,
You should have no problem making 400whp with the hardware you currently have. You will need a transmission solution if you actually want to have fun with that kind of power.

hmm, thanks, but why go back to the stock manifold? I am wondering because I haven't put the sheet metal one on yet...yet.

I would probable go with a bigger set of injectors other than the STI's say like the PE's. You might be maxing them out with those numbers..

Exahsut manifold, not intake manifold ;)

The pe800's will be ok if you just want like 400 on pump, 500 on c16.

wow, thanks for the info! What do you think of Kingpin's setup, as opposed to Gruppe-s or the Crawford ones?

Hmm my daily driver has a built motor, and a 35r kit. ;)
i'll cut you some slack since you are old school tri-state. :p i've seen your old ride at last years tri-state meet and i know you know what you're doing/talking about.

I'd stay away from PE's. they do not transition very well. Causing stumbling and can be confusing to problem solve.

400whp on a wrx, is going to cost lots of money. Been there.

I have already spent tons of $$$. Now I have a ton of brand new old parts to sell!

Why thank u :D

9vapors.. I pm'd ya

You can get 400+whp from GT35R but ,,,,,,,,,,,,,,,,,,,,
what are you going to do with your engine and gearbox what is the size of the JUN cams ACT clutch is not a good idea because if you are 400+whp that’s like 500+hp on the flywheel sorry to put you down but its should go like that

Hey Cronic, where are you guys located? So if not the PE's, then which injectors to go with? Also someone said earlier that I should go back to my stock exhaust manifold, is this true, and why. For the most recent post, I have a ACT 2100 clutch, Fidanza lightened flywheel, and the Jun kit is the 264 cam kit, and supertech valves. On the cams, should I have gone with the 272's? Anyway, thanks for all the help!

No don’t go with JUN 272 it’s too large its will make your Scooby slow your block is 2.0l i think.

Most of TONY RIGOLI 9sec cars have a stock exhaust manifold and flywheel
don’t go lighter than 6kg on the flywheel, you will lose Torque after you shift to 3rd.

PE 550cc or 660cc injectors are fin but don’t go large then you need a good ECU to control them.

your ACT will kill your gear at this power rang if you want to safe your gearbox fit the ACT with the Subaru organic disk to make it essay on the gear

The ACT 13.9 lb flywheel is hard on gears?????? Please explain. I've been busting gears.

Got is backwards. Lighter flywheel is easier, especuially when downshifting. Less intertia and shock. I ran JDM ver8 motor with 5my and Exedy 13# hard as hell for 6 months before going to 6mt and that was only due to the desire for better gearing.

You are off base on alot of things man, you should really rethink before you give advice..

272's will not make your car slow..

550-650cc is NOT even close to enough fuel for that turbo.

I agree on the exhaust manifold, and flywheel.. I do not like lightened fly's.

The act is harder on the tranny, but if he has a 6spd or dog box it isnt going to be a problem..

you will lose Torque after you shift to 3rd.

Function oif horrid gear ratios not the flywheel. With the JDM 6mt, or proper close ratio 5mt gears like Kazz, this is not an issue. The problem with the 5mt is you drop out of boost with each shift. A heavier flywheel does zippo to solve that.

You get me wrong cronic

The 272s it will make power on 2.0l like close to 6500rbm not good for wrx on the streets that’s what I mean, in another hand the 264 will performs batter and the JDM sti cams will work will too.

I know for 400whp needs lager injector and as he explained his block and gear are stock so its not going handle this power rang for long so I advised the safe mode that’s it

Hope you get me Scooby driver

He is going to be running a built 2.5l as he says in his first post.

Oups………… didn’t get this part 2.5l :p

Then its goes like that
JUN 272s are fin you can get 8000+rbm, this cam size is very good if your GT35R is 1.0 A/R, PE850cc most have them with fin Fuel Rail Kit
Upgrading the gearbox is priority at this power level

OK
2.5 and the 35R kit. What is the size of your AR on the turbine?
how big is the exhaust inlet for the turbine?
Your stock exhaust manifold gives you more velocity for that big turbo to spool. Headers are great for smaller turbos but they take a while to heat up because they are stainless. If you use the headers heatwrap EVERYTHING manifold up pipe and downpipe this will keep the gexhaust gasses hot and flowing fast. Also you might want to cansider the TGV delete for the intake.
Perrin modified 800s would suit your needs for 400 or close to that. They are a bit cheaper than buying new injectors. Your EM could work with a custom tune by someone who knows how to tune the UTEC. I have ECUTEK and havent had any problems the only thing that is a pain is getting a custom tune every time I tune. Hope this helps.

Dont the Jun 272's make for a very rough idle, therefore making a very rough daily driver?

Shouldn't the title of this thead be I want a new transmission?

You are going to need a decent amount of fuel. 800's are probally going still be cutting it close.
You or Clark don't suggest modded stockers for gt35r kit?? How much are PE800's anyway?

Eh, I know my tranny is going to fall out. Time to sell it, and get a dogbox or 6spd. I also need to sell my headers, and try to find a stock exhaust manifold. I will look into getting some TGV deletes, any suggestions on who's to go with? I have only seen the APS ones so far, but I know a couple of other companies that have them. I have decided to go with Cronic and the Kingpin crew, and get their GT35R kit. I might even be able to make a trip to AZ to have them do the work. Thanks for all the info all, come December, when the work starts, I will post all the pics, and all the stuff I will be selling!

Mike, Are you running side, or top feeds on your build?

Pe650,800,850 are all about 650 i think..

Call me up on monday and i can tell you what i would reccomend for you as i know what your car is going to be used for :D

Am I the only one that notices this....This guy can buy all these trick car parts..but he has no idea how to use them.

Maybe you should take baby steps.

Yeah because everyone who asks questions online accually builds the cars they talk about ;)

Good luck on your build up man :lol:

The only ones that suck are the APS ones as you seen need to gasket match and smooth out the interior. :rolleyes: Considering they cost a car payment, you'd think they'd be perfect.

HAHA, wondered how long this thread would take before the haters made it in. I am paying a lot of $ for all of my parts, so I want the best and to know exactly what the experts like Cronic and Kingpin's crew suggest. There are not a lot of people with these parts because they do cost so much, and even less that are serious about making the power that I want, so why is it bad that I am doing the research that it takes to make that power? Anyway, as far as taking baby steps, I have taken them all, and am ready to move up to the big steps, you can see my current setup at www.cardomain.com/id/silverwrx. But really thanks for your post.

Thanks a lot Unabomber, this is exactly the info I was looking for! I would have went with the APS ones too...

Since you are spending, spend for a JDM ver8 manifold and skip the TGV hack. Good luck!

Thanks ebeck! I hope luck is with my engine and tranny when I finally get the parts put on. I will look into the ver 8 manifold, not sure why that would be better, but I guess I will find out.

Because it is one piece, and goes right to the block. Rather then having the manifold, then a TGV-less riser, then block..

325-350 is so much easier attained and much more reliable. plus 400 as a daily might be a bit much.

any who. good luck.

This thread is two years old. A lot has changed since then. 500whp daily drivers are where it's at now. :)

Lol @ this thread... I was such a noob...

i hope this isn't your daily driver. goodbye reliability!

IByoushouldhavestartedwithadifferentcar

gotta love the ingnorant and narrow minded...

you should get some 800+cc/min injectors as you can top out 1000's on a 35R with a poor BSFC (lots to do with the shortblock and combustion chamber). Also get a good EM, either Hydra or AEM and talk with your tuner. For DD I would personally run a hydra.

If you can, I would urge you to do STi heads or get a port job done on the WRX heads, as the ports and valve sizing will become your limitation. I would do this instead of the intake manifold at this point. The heads will make 400whp with the setup you have going though.

Sounds like it'll be a fun DD once your done though.

Drivetrain is what you should bulletproof to make it a reliable dd though.,

Am I the only one that notices this....This guy can buy all these trick car parts..but he has no idea how to use them.

:lol: Not only that.....but ounce the tranny breaks its goodbye savings account. And asking for only 400whp with a race tune with a 35r is an insult to both the turbo and the axis motor. Many of these setups make 600+whp on racegas.

^^ and looking at thread dates owns all of you lol

holy crap, that was the most random bump from the grave i have ever seen...random comment on what is safe power to go for.... :lol:
