Hey tech

So i finally have the funds to start buying turbo stuff for my 91 z28 camaro build. I have a 99 .030 over lq4 with flattop forged mahle pistons, stock 317 heads with tooley springs, 223/223 .610 lift 114+4 lsa cam, ls1 intake with 80lb siemens injectors. Stock computer with a 3bar map. Walbro 400lph feeding a -8AN feed and -6AN return. Ill run fbody accessories for clearance and use flipped truck manifolds for the hotside and dump out of the fender. Id like some help with buying the right turbo parts so i dont make a mistake.

Id like to use a S400sx-75 but im unsure which a/r to buy and which turbine wheel size (83, 92, 96)
Ill use a ebay intercooler and piping to go with it.
BOV ill likely use ebay parts as well (heard decent reviews on them)
wastegate ebay as well.

Thanks.

I'm no stranger to buying cheap parts, but don't cheap out on a wastegate. Too much relies on its optimal performance.

Look into JGS for the wastegate and BOV
