Question Any high powered bolt-on kits for RS?

I'm looking for a bolt on turbo kit capable of 400-450hp at the crank. I want a front mount intercooler and external wastegate. I can't seem too find anything that fits this discription. Would I be better off buying the parts I want individually and having the rest fabricated? I know shiv was talking about a high powered kit, but I can't find any info on it.

Any kit that will be that high-powered will be a custom fabricated kit. Simple enough to make, just isn't out there because there are so few people that'd go for it due to expenses.

How much HP does the FAT stage 4 kit put out? More than Shiv's?

The stage IV kit, even combined with the tec-ii puts out less hp that the stage III kit. The design behind the stage IV kit is show and super fast spool up.

I ran my stage IV kit @ 11psi, with tec-ii tuned by Shiv, 3" exhaust, Vishnu fuel rails and tons of other toys. I had to take the kit off and got a stage II. It was fast with the stage II than the stage IV.

I don't think it is more than Shiv's. FAT stage 4 is lilke shiv's first kit. shiv's T3-T04with 3inch down pipe & external wastgate is bad ass! if you are really serious I would think about talking to shiv and taking half of his kit, turbo up-pipe down, pipe intake and having someone make you a front mount intercooler and piping! the only problem is you may have crazy turbo lag, with the top mount from shiv I have full boost at 3900RPM, 3400RPM on cold days. Just something to think about! If you put 450hp out of the motor you couldn't run a trans strong enough to hold that, unless you wanted a full dog box, which some people are breaking. good luck!

Overall, 400+hp is gonna cost you, if you want it reliable. Ballpark estimate, I'd say about 7000 for the turbo kit, fuel delivery, electronics, etc. 3000 for some sort of builtup transmission. And about 5000 for a builtup engine. None of this includes installation costs because this isn't simple bolt-on stuff. So.....

I know it is a bit more expensive than other options, but the idea is too purchase a Cobb Tuning Stage III Short Block and Stage III Cylinder Head Package which will be installed at the same time as the turbo kit and Tec-III(?). I have a good shop about 45min from my house (TRi) that can do the fabrication for me so exactly what parts would I need too purchase?

Turbo (T3/04 or T04)
External Wastegate
Blowoff Valve
Front Mount Intercooler
Headers
3" Exhaust

Thats all I can think of off the top of my head.
Cant forget the tranny (Chalek?)

you list is missing a few things

-some huge friggin injectors, fuel pump, parallel fuel rails

I think you mentioned everything else. also, after thinking about it, I came to the conclusion that it wouldn' be that hard to do, but it would be expensive. for example, SCC turboed there 2.5rs with stock internals, tmic, tec-ii @ about 9psi and they got 290 whp (although it was converted to Fwd). that should equate to about 360 crank hp or so.

now, if you have a fully built engine, fmic, tec-iii, a big turbo and lots of fuel, and run about 10psi, then you should have no problem getting atleast 400 crank horsepower.

the only problem is the tranny.
horsepower costs money, how fast do you want to go?

The goal is too have something I can drive too work everyday and then turn up the boost at the track and pull off high 10's. Sounds reasonable right?

I'd actually love too have even more power than I stated, but I refuse too get rid of the synchros in my tranny and thats all the Chalek is rated at. Unless theres a better synchro tranny out there (no more than $4k though).

There is a Chalak synchro set out. Talk to Larry Ganz (imprezars.com). There was a group buy on them a while back... you can check the vendor gb forum (or vendor classifieds) and see if you can find it to read more.

OK. I have a Stage II FAT kit, low compression pistons and strengthened rods, TEC-II. fuel rails, 3" exhaust and a STi V4 tranny (clutch, flywheel, rear diffs and axel, the whole damn show)...

Even if I run 15psi, I don't think I'm going to get anything lower than Adam Blooms 11.88


You want 10s? Smoke some crack, find your self about 25k, and maybe it'll happen.

10s should be doable on 2.5L with a lot of boost! far less I'd wager but it's gonna cost ya.

turbo EG33 is probably an easier way to get there. custom firewall, RWD conversion, engine set back a foot or two...

ah it's fun spending someone else's money.

Im hoping to keep all the engine and tranny modifications under $20k and Im not going to smoke any crack. The Chalek gears I was referring too are the synchro'd set.

That Cobb stage 3 short block is the key to making a lot of power. Cobb's web site says that it can handle 600hp and over 30psi, that should be more than enough to get you into the 10's.

the Chalak synchro will not hold up to the torque.

I have not heard of one sucsessfull synchro setup that will hold over 300-320 HP for the long hual on a 2.5 block.

I know I said I refuse to lose my synchros, but it looks as though I may have no choice. I know that if I purchased a full dog-box I would have to learn how to rev match and what not, but exactly how difficult are these things to drive. Im a decent driver, but I far from being a professional. My only concern with the dog-box is dropping all that cash on it and not being able to drive it properly.

I see you're up in the icebelt... is this going to be a daily driver? Dogbox engagement in the slippery stuff could cause you lots of trouble if you're not ultra smooth, AWD or not... especially with all that torque on tap.

Also I'm thinking that you might need an LSD front to get the most of the power when you're launching? Just a thought.

High 10's??

I think a WRX just broke into the 11s and it was modded to hell and back. You may not need the crack, but you might as well buy a new 'Vette with the money you'll need to pull those numbers.

I can name 2 WRX's in the 10's off the top of my head... neither on this continent, though. One is an auto, as well. 10.02 (dogbox) and 10.6 (auto).

Actually me and my RS are in Kutztown, Pa now so snow is no longer all that much of a concern. Of course the cooling system is going to be a bit more important.

While I can't comment on Challak's syncro set, I can highly recommend against their dogbox set as a first hand whitness to their slow and painful death on a freeway.

Don't even get me started on TRi's work... Poke around the Tri-State area forum and ask them what they think...

Jim

PS... If you want a reputable shop, go to Rallispec in NJ. They can do almost any custom work and fabricatiion you can think of or afford. Lately they've been busy fixing TRi's past customers.

Our turbo kit at www.ImprezaRS.com/turbosale.htm with extra fuel injectors and timing control can make 320 crank hp at 10 psi on the stock 2.5RS. It can do 360hp @ crank with race gas or low compression pistons with good engine management before you hit the limit of the extra injectors, the VF22 and the intercooler.

Shiv's latest turbo kit will do 400-450hp with proper engine management and built short block.

The Chalak Synchro set will handle 370-405 ft lbs of torque, which means Shiv's kit will overwhealm them when maxed out, although they are perfectly matched to our kit.

The Chalak Dog Box seems to have increased reports with broken shift forks or other things like welding/seizing the 1st gear bearing that then take out the gears. But the synchro sets have not yet shown failures, with 50-60 sets on the road. Mine have seen 14 psi and 360hp on race gas on a cold day a couple of times, and 12 psi daily since they were installed approx in April.

The Chalak Dog Box is the biggest peice of crap on Earth. Not only is it the most poorly conceived piece of sheeat, but he will not support them once they blow. Now, they don't blow six months to a year later, we are talking a few weeks. On four Dog Boxes now, he has blamed the problems on poor installs. He is a very bad man in my opinion, and takes advantage of the fact that he is in Austrailia, and that we can't afford to fly down to his shady place of business and beat our money out of his sorry A$$.

ImprezaRS: You obviously deal with Haysam a lot. Do you think you could help out the broken dog box owners out by swaying that thief into replacing the gears with something else? We would all appretiate it.

Chalak dog box owners: I fly practically free, any interest in sponsoring a trip to down under so that I can deal with this thief in person?
