Got some money, want some power+stick

[david_12121]

Hey guys...not the first time I'm asking about this but this time I actually want to do something about it!
My parents are very unhappy with my motorcycle, so I'm selling. I'll have 8-10k for some upgrades to the SVX to keep myself from falling asleep on the road!

Right now I have three goals:
>Manual transmission
>~400hp
>a rear biased SVX!

For the manual, what should I buy to have a rear biased power distribution? Do the 04ish STI trannies handle 400hp? I don't want it to be bulletproof, just reliable enough at a cheaper price. Not going to be shifting and launching like Honda drivers!
I personally love Toyota transmissions...is a Toyota swap possible at all? (sry if it is a dumb question)

Power is probably the easiest to achieve! Will it need to be cammed for a single turbo?


Anything else?
Thanks

That's a small amount of money for a lot of power on a uncommon car with next to no aftermarket support....

You'd be much better off getting an Impreza/Outback/Legacy and doing an STI swap into it. You'd need more than $8-$10k to build the SVX engine up to being able to support 400HP, let alone make that much.

I have actually done quite a bit of research. Software and injectors give 300, right? After that you cam it for less compression, turbocharge, and minor rebuild. How much more is there to it?
Doesn't seem that much power for a 3.3! That's just ~120hp/l, so unless the whole thing about the EJ33 being bulletproof is nonsense, I don't see how it's gonna cost that much! (did I mention that I'll be doing it myself?)
How about the thing about rear bias? Do any of the STI's do that or will I be better off removing the front axles and locking the center "diff"?

STI 6-speeds with DCCD are rear-biased, and very strong, but far from cheap. The USDM 06 STI DCCD 6-speed is, IMO, the best option. It has a newer style of DCCD from the earlier ones, but retains the internal oil pump, which is absent from the newer ones. The gearing is also pretty well matched to the EG33.

Read through my turbo thread and you'll get a feel for the expense/challenge of getting more power from the EG33. The first thing to consider is engine management, which is discussed to death in the turbo thread linked in my sig.

Software and injectors will give you nowhere near 300hp. Just ain't gonna happen. Not to mention that the EG33 is an open celled engine with very thin walls, so good luck getting massive amounts of boost to not grenade the engine...

The EG33, just like many other engines are basically bulletproof stock. When you start sticking boost into an engine not meant for it, that is running high compression, it will grenade, especially without the proper tune. That has nothing to do with the durability of an engine.

And good luck with injectors and software giving you 300hp... you clearly haven't read even half as much as you think you have...
