    I noticed alot of p trims forsale lately would they push enough for a 393 stroker? I wouldn't want lots more power just alittle more.

    Thanks new to the turbo world. 88 fox GT is the car and its carb.

    P-trim is away to small for a 393 unless your running twins.

    P trim is only the exhaust side and doesn't help much.

    A lot of turbos you will find up for sale (eBay) are meant for diesels and may have a P trim turbine wheel, but the compressor side is usually too small.

    WRONG.

    A compressor that is too small will run out of air flow (pounds per minute) and won't make any more boost, just more heat.

    A compressor that is too large (high boost but low flow) will just surge. Bad.
