Forced Induction Conversions'

[Shay]

Ok hi guys, im seriously considering doing a forced induction conversion on my car.

Want to know what is involved.
leaning towards SC as there is a shop over here that does MR2 ones for about $600.

so my shoppin thoughts:
S/C
Piping
Inlet manifold to S/C adaptor plate
SRiT/VXR injectors (??)
Fuel pump
FPR
decompression plate
FMIC (do you put a fmic between filter and s/c?)
Piggyback ecu (??)
belts.
extractors
flowed head.
flowed intake manifold

so can you think of anything else?
is it safe to run your water pump slower, if so might add a underdrive belt.

you are forgetting your drivetrain.

urs is an auto yeah? will need to look into ways of strengthening it or something (i havent looked into this myself yet so im unsure) because with any big change in power, the transmission has to be able to handle it

thought the box in it was good up to 350ish hp?
my aim is for ~250-300 hp

I don't think its worth it eh unless u have a money tree out the back.

Even if money isn't an issue your car being an older girl, reliability will completely disappear. It will be a never ending project that will cause hassle after hassle. That's just my 2 cents.
IMO you will always be better of buying a turbo and modding that to your liking.

hmm, well i dont plan of sellin this car anytime soon,
and my thoughts were, spend 6-7k on this, or buy a 1jz supra for the same money.
and this car is pretty damn reliable, and i love the extreme sleeper idea.
while the supra would be fun, IMO would cost more to make it as powerful/reliable

Unfortunately you'd probably be looking at heaps more $$$ than that.
Like I said the car being reliable now, not so much after conversion. There are just so many things that can go wrong.
What about an engine conversion?

I wouldn't run the water pump on a turbo converted car slower then when it was naturally aspirated...

Also the FMIC goes between the s/c and the manifold. If you're not planning on running much boost, they're often not used for s/cs (eg the s/c conversions on the ls series), as it adds a lot to the charge length going from supercharger -> fmic -> inlet manifold, and isn't as necessary. But it sounds like you're aiming for a bit, with decompression plates, so probably worth looking in to .

Sounds like you've thought of pretty much everything - only suggestion is what's the stock AFM on your engine? It may only be rated at the airflow for 150hp or so, in which case you may need larger.

thanks mate.
thats pretty useful, dont have much room for a fmic anyway.

hmm yeah AFM, would def have to look at that.

You can run a clamp, or would probably do away with it using aftermarket ecu.

Hell no! 1J would eat you up and run for twice as long with the same $$ spent.

the 1j would be a second car, not a replacement. so 6k mods to mine v 6k 1j
power/weight i would prob have the advantage.

it is true this prob will never get off the paper, but ive been doin heaps oof lookin around on this forum and other opel/vauxhall ones and there is pretty much no advice on what you need or need to do.

so even if this doesnt get anywhere could be helpful for others.
supercharger is new. just made for MR2's.
