vg 30 turbo on a ca18det? makes sense or nonsense

with the compression ratio being 8.5:1 on a ca18det...
will the exhaust gases spool a vg30 turbo effectively or will it start to make power at too late in the rev range?
this turbo on a high compression engine spools quite decent... not shabby at all...
anyone kno approx when this turbo should start to spool? someone told me around 4000 rpm's which is much to late for what i want.. looking for something around 2500-3000 spool for the latest....

or should i just go with the t25 from the SR 20? :?:

or should i try to build a hybrid from the vg? with the ca backing?? so many questions... no answers.... :cry:

ca19 where u??

If I not mistaken... VG30 turbo is a T3? Not a bolt-on, the SR T25 is a minor upgrade... if you get a T28 ballbearing from S14, S15 it will be a nice bolt-on upgrade. Of course that may all be hogwash... I not too knowledgable on the topic.

yes it is a t3.... the t25 and t28 from the sr are both bolt on upgrades for the CA18DET.... but a manifold can be built for the t3 to work on the ca18.. i am not asking if it is possible.. it is if it makes sense...
