Newbie Question

[JamesB]

Hello , I am new here and new to skylines !

I bought a 93 R32 GTS4 a few weeks ago and I just have a few questions about it !

It has an apexi dump pipe from turbo to cat then a cat back jasma 3 1/4 inch system ,

and an apexi safc ( the old one with 5 knobs ) and an oil cooler !

It still has the stock front mount intercooler .

The turbo apears to be standard with no aftermarket boost control , it just has the hose from the front of the compressor housing to the wastegate actuator .

It is running around .8 bar of boost which I think is around 11 psi .

The question I have is , is this a safe amount of boost to be running for the standard turbo ?

Does this sound like the right amount of boost for the standard turbo , or could it be fitted with an rb25 turbo ? and is the safc needed if it is mostly standard ?

Any help would be great ! ! !

Thanks

32s usualy run around 10psi stock so it sounds right. the exhaust would give it more flow and might have givin it the little bit of extra boost. ive been told the standard ceramic turbos shouldnt realy be taken over 14psi. hope this helps

yeah thats the right boost for a stock R32 turbo, ~10psi. you dont really want to run the stock r32 turbo anything above 13-14psi. to check if its a stock 32 turbo have a look at the compressor housing for a marking "16v". but from what your saying about where the wastegate actuator gets it feed from the compressor housing its a Rb20 turbo. Rb25 turbo takes the wastegate line from the elbow that bolts onto the compressor outfeed.

the safc isn't really needed on a fairly stock setup but it wont hurt. it'll help you get better perfomance and fuel consumption than the stock ecu by itself.
