Default Turbo it?

alright this is not the same thread as all the other ones. im not just wondering, im actually in the situation... my friend just totalled his WRX and is parting out a lot of parts to our group of suby friends. he wants to see me turbo my car, so he said he would sell the turbo, intercooler, and most of the other things i would need, i know next to nothing about turbos... if i went threw with it, it would be in 2 or 3 years, but i would buy the stuff now because its the only time i could buy the stuff for the project this cheap. (i dont know exact prices right now) is this a good idea? would i have a lot of problems? suggestions? ideas?
Thanks,
Greg

fuel pump
fuel pressure regulator
engine management-if you wan't it to last
up/down pipes. they sell some that fit the RS manifold
actuator spring-so you don't make so much boost

I don't know much else, but you can go to RS25.com to find everything you need in detail. Ty searching the forums there, because almost everything has been covered. Let me know if this helps.

It will Save alot of potential stress and effort, if you just pull his complete motor and swap it whole...its a very do-able swap... you can find many threads and walkthroughs to help with the swap...

if you want to go turbo...put in the turbo motor...

Ok, back to the question at hand, what all will you need to turbo your RS... Well if your friend intends to make any money on this part out of his, he should be selling the motor and tranny and all that complete, unless the motor dont work. If he for some reason not selling it complete you will need lots of various parts etc. there are lots of lists in lots of places, but to really make it easy on yourself, just buy a complete used kit from someone on these forums, 1.5-2k and you'll have everything you need.

FYI if you do still try and do a conversion somehow understand that ALOT of parts from that rex will need to be modded and you might as well get different parts that already work like... the intercooler won't fit w/ out modification... the this, the that. Especialy if you know nothing about turbos, you should really be reading and reading and reading!

Some links:

http://auto.howstuffworks.com/turbo.htm - Read if you don't know anything about turbos...

http://www.rs25.com/forums/forumdisplay.php?f=7 - Read the 1st post "Official turbo..."

http://forums.nasioc.com/forums/showthread.php?t=185230 - Read em all.

And after all have been read and understood, you may then ask questions. ^_^

Good Luck,

Nick

PS- might want to look into swaps as well, just so you can compare the costs of turbocharging your car, and swapping a wrx/sti engine into your car.

PPS- ALSO, your going to need to put in a new clutch, yours will be no good. Go easy on your transmission and you won't have to replace your transmission. And get a new cat-back exhaust system.

Understood. One thing youre forgetting is a turbo crossmember, for routing of the exhaust, and while I know the turbo front antisway wont work on NA cars, I'm not sure if the NA front antisway will fit a turbo conversion.

On a 2.5 liter if he runs low psi does he really need to change out his stock clutch? If hes only getting say, 25 HP from it should he be ok? I thought the stock clutchesare good to around 200HP. (I drive Legacy, think its the same as 2.5RS).

"with any large increase in power you need a stronger clutch"

if he's only getting 25hp out of it(3-4 psi perhaps?) then he *might* be okay... but you don't want to notice some clutch slippage and have no money left over in order to fix it when it becomes a problem.

that said, yes if it's a small increase in torque then you might be able to get away with the stock clutch. and since he's not thinking of doing any internal work or anything the "while you're in there..." mentality isn't really applicable.

Well I'm going to be running 7 psi, and that will push me up at least 100 hp... so yea... I think he will need a new clutch.

I don't know, are you going to drag race this thing?
If so, then yes. Otherwise, I would suggest buying
one of those +25% clutches with the stock pressure
plate for $100.

You can get one at SPO Motorsports
http://www.spomotorsports.com

If you're not dropping the clutch at 6000 rpms, then
even a new stock clutch will hold up for a long time
(3 years so far, here).

And that's running 7-8 psi, for 3 years.

If he gets the up pipe that is made for retaining the stock exhaust manifold then he doesn't need the turbo X member. You would need to tap the oil pressure sensor with a banjo fitting and get some good oil lined that you can trust not to leak. Get the coolant resevoir from his car and tap the heater hoses to supply it with coolant

But the clutch is a good idea considering the wastegate spring cannot be changed so it shoud be making 7psi about if there are no real bad leaks. so figure an increase of about 100hp at the crank, you will probably fry that stock clutch if you drive it hard. Of course you are going to romp on it, otherwise you wouldnt be turboing. If you want it to last you will buy an emanage or a perfect power to pull timing.
