Ok HT here is my question. I have a crx stock 81mm ls bottom and b16 head. Got a t3/60-1 garrett 70 trim. Now the car is untuned and im driving it around (not boosting it) to work bugs outta it. My question is that while im driving it im still turning it 5k-5500 I was woundering at what rpm this turbo on stock 81mm was going to start to build boost?

If you can keep out of the throttle enough to not spool the turbo you could probably take it to redline.

There wouldn't be any point at all; but you could do it.

I have the same setup in a crx w/ a t4 60-1 and hit 20 psi @6k, but I have a intake mani, and cams and a ramhorn

i have a 84mm lsvtec with a t3 62-1 ball bearing turbo the back housing is a 63a/r and it see's 10psi at around 5500rpm.

ok so with stock 81mm its not uncommon to see 5500 rpm if not a little more for full boost its got a miniram horn manifold but stock intake and gsr cams.... I guess going to have to bump timing a little to hopefully liven it up a little. IDK any suggestions

when they say they spool at 5500 or 6600 or what ever, thats usually full throttle.

Soo if you can stay at maybe 25% throtle (+ or -) 10% I think your safe, Be carefull thats a pretty powerfull turbo it wont take much boost for that turbo to flow

cool sounds good I guess Ill just have to wait to see what happens when its tuned.
