| But ALOT of people with GT30 or GT35R's are doing 500whp on pump gas. The guys with the 42r's are making over 700 all day. buddy of mine in a sleeved 2.0l GSR made 832 no nitrous. His car is a DRAG only car. Has a spool not a LSD, car is gutted/caged ect. His brother who I have multiple video's of did 432whp on 18psi on a t4-61 with a 70ar intake makes 567@28psi on race gas. Could a Z make 500whp+ on pump gas. SURE. but..... your going to loose your low end tq and you take away any point of keeping it a fast spooling fun street car. So if your looking to keep it streetable and fun to drive and not just a high RPM HP monster then you will go with smaller turbo's Think of it like this
Bigger the turbo the more of lag and not as fun to drive on the street.
Smaller the turbo, Faster the spool and alot of fun to drive on the street because your power is always there not 5000rpm or more.
