Title: turbo lsvtec holset or precision
Post by: shanerv on February 13, 2014, 11:55:09 AM

So went to VA this December and picked up a completely rust free 92 si. And I am building a lsvtec for it for this summer. Stock rods and pistons complete rebuild. Gsr head with port and polish. Gonna be my dd 100 mi a day ride. Looking to make 350 on pump and 400 on race I just happened to get two turbos for free. Which one would you run?

I want to say holset but the 16cm housing is gonna spool a little slow.

when i say a little slow, my 12cm on a splog with a lsv hits 26psi by 5500. now if I run 12-15psi i see it by 4500. But its a blink of an eye from 4500 - 5500. Just don't expect to cruse don the hwy @ 3000rpms and stand on it and expect boost right away.

I used to run a lsv with a h1c and 18cm exhaust little slow on the spool 4500-4800 full boots but it didn't bother me. I am wondering though if at only 12-15 psi if it will even be in the efficiency range of the hx40 compressor or I will be below it to far. I also used to have a ls with a hy35 @12 psi and it always seemed like it was just kissing the efficiency range but not quiet there.

For the billet wheel u will have to machine the backing plate but for $30 more go with the base setup 62mm inducer 86 ex with a 7blade wheel

I vote holeslut, I'm going with a hx52 this year over my precision 6766 that barely survived dyno time, maybe 1000(really pushing it) kms, and a few track passes til it let go and started smoking.
