Default Turbo 2.2 questions

So I have pretty much everything to put a vf48 I believe on my 2.2 95 PC. All I'm really missing is the turbo oil and coolant lines which I think I have sorted just need to order.

I've heard at less than 7-8 psi no tuning solution is absolutely necessary,but always preferred. Is this true? Plan on running 3-5 psi to start and when I know everything is working fine getting a standalone.

Also for the oil feed I'm going to tee off the sensor behind the alternator. Will I need a restrictor on the line? Not sure what kind of pressure is there and can't find info about it.

You need a restrictor if that turbo came with one in the banjo fitting / supply line oem. Oil pressure there is pretty much the highest, but it wouldn't matter if you got it there or from a location on the rear. The restrictor is going to limit what the turbo gets either way.

It depends if your car is MAP or MAF. Personally, I did this and i have a MAP car. It blows. If you are MAF, you can run 7-8 psi(the ecu wont allow any more than that) somewhat safely, HOWEVER, if you are MAF, even if youre running 5 pounds you will get stupid fuel cut when you try to go full throttle, and there are solutions to that. There is a facebook page called NA/T Subarus, and they have a full guide for doing the conversion along with a lot of help.

Most engines can handle it but really, you should only tune if you want it to last. 3-5PSI is actually quite a difference to the computer.

cheers

Question for this thread
I've got an NA 2.2L brighton wagon, and most of a turbo kit for it. Ive heard you need a different crossmember of some sort to allow room for the turbo piping. Which cross member is it? I have a rhd turbo parts car I hoping I can rip it out of

That's the crossmember you need.

1. you can run up to 10 psi before the stock maf gives up. the 2.2 will handle more than that, the maf won't.

2. you don't need a restrictor pill for the oil feed line. feed it oil. drain it's oil. simple.

3. you don't have to tune. i did not. i used a RRFPR for a while and then took it off. AFR's were better without.

4. get an AFR gauge. it will show you a LOT of info about what you need to do.

5. oil feed i would suggest using the front port under the alternator. put the dummy switch in the rear port and extend the harness to keep the light off.

check out my members journal for a LOT of this info. also a LOT of what not to do. boost shenanigans start at post number 3072. feel free to start from the beginning for tons of stupidity.
