Potentially Terrible Idea

[Fungus Mungus]

now i'm not sure whether i'm looking for advice on a "how to" basis, or just someone to tell me that this is a dumb idea and to walk away, but here's the thing

i own ONE car. 1996 r33 gts. rb25de etc. you all know the drill

when i first bought it i had a bit of extra cash lying around and managed to score a big ass intercooler and 2 garrett turbos for a matter of a couple hundred bucks.

basically, all this is leading to one question

what kind of work/how much money will it take to make a functional and RELIABLE rb25dett??

i've been told everything from "bolt it all on and away you go" to "you're going to have to replace every mechanical part of your car"

is there a simple way of doing this or have i dug myself a hole that i should just fill in and enjoy my naturally aspirated goodness?

if anybody could shed some light on this for me i'd greatly appreciate it because i have this horrible feeling that i'm in waaaaay too deep

it's not just a matter of going out and buying a gtr or gts-t any more. it's come down to wondering if it can be done without spending more money than just buying a new car. don't get me wrong, i'm not just trying for the ebay special, if something needs genuine good quality parts or professional work done i'll go there, but it's also my daily driver. i don't want it to be off the road for more than a weekend at a time.

the things i figure i'll need to do so far are as follows:

aquire remaining parts required ie. intake/exhaust manifolds, dump pipes, cooler piping, oil lines, etc.

upgrade fuel pump

upgrade injectors

possibly upgrade diff, gearbox, clutch

possible engine rebuild and have head worked/decompressed/whatever

have i missed anyhing? anything there not required?

can somebody giz a hand here?

from the little bits of info I'm come to know, here are somethings you might want to consider.

Factory injectors and fuel pumps run out of juice around 210-230rwkw so you can have 4 truck sized turbos hanging off the side and you still won't make anymore than 230rwkw.

I'm thinking the exhaust manifold will have to be replaced with custom ones to fit the two two turbos.

New twin dump pipes will have to be either purchased or replaced.

Aftermarket engine management

Inside the engine, I've heard you will have to change the pistons, something to do with the change in compression. Will also have to change the gasket as wel.

Pretty sure I'm missing a few things

Injectors - $900

Fuel pump- $200

twin afm - $500

exhaust manifold - beats me, anywhere between $400-$1000 I guess

Power FC- $1500

New pistons, conrod etc etc - dunno a few grand or

gasket - don't have a clue

a tune - $500

Dump pipes - $x00

well, thats as much as I know.

your better off selling what you have and buying a nice high flow.

Its going to cost you too much for what you get and it will be a bit laggy

did you guys also notice that its a de... compression, smaller injectors and ECU then RB25dets. Sell the motor and buy a RB25det with ECU. There is a thread in the N/A section about putting turbos on de's, its really not worth it!! when you can get a det motor and put that in. Besides then your engine plate wont line up with whats really in the car, sell it and buy a GTST or GTR!!

Sell the car and buy a turbo model, you will have a much better base to begin with.

de box = rubbish.

de diff = rubbish.

de brakes = rubbish.

by the time you've brought those up to scratch with a stock gtst you've spent 3k plus labour without even looking at the engine.

Just grab all the pieces from a gtst and install them onto your car - go single turbo. Install a spacer/swap pistons, larger injectors, ecu. Valve springs might be a little soft for big boost.

Way too many isues going TT
