68mm? cant say ive ever come across to many of these before! sure it isnt a 67??

[osofast1jet]

No its a custom Comp 68 mm extendid tip turbo, I try alot of there latest turbos they have out, as I am a distributor for them.

[osofast1jet]

I know it sounds crazy as it is a very small exhaust for 30+ psi, it is the 2nd gen TRD exhuast and a rps manifold

thanks

Thank you for actually knowing how to shift.

Small turbos have less rotating mass than larger turbos. A small turbo will spool faster, and at lower rpms. A big turbo usually takes about 5000-7000 rpm to acheive max boost, depending on application. Some people prefer to have earlier power in the rpm range, but when trying to make even more hp, only a bigger turbo will suffice

@vXGWOODXv I realize you responded 8 months ago but Ive owned an MKIV for several years now and I'm a contributing member on that forum so don't make assumptions about things you know nothing about.

@vXGWOODXv By SF you don't mean stoner forums do you?

[vXGWOODXv]

@53drag0n Worry about getting the Supra before you worry about numbers, there are people like you on SF everyday with these kinds of questions. Search the Forums for answers.

[53drag0n]

do any of yall have any advice for a young supra-to-be owner, wanting to pull numbers like that??

@dwnrety1 oh yeah, well then you'd be right my friend!

[dwnrety1]

@BJs4MePlz right, i forgot about small displacement v8s..

when i think V8 i think more of a big block chevy.. you know, 6+ liters... lol

[BJs4MePlz]

@dwnrety1 that does depend imo. the cylinder sizes depict how mch exhaust.

for example a v8 4.0L wont give more exhaust then a 6 cylinder 4.0L

[dwnrety1]

@BJs4MePlz or add cylinders.. a 68mm turbo will spool faster on a V8 than on a straight six.

more exhaust=more rpms in the turbo

[BJs4MePlz]

@tarkuk The only way for a big turbo to spool at low rpms, is to have a big fuck off intercooler, usually custom made.

for example.

went from 4500rpm max boost 17 pound. from a evo 6 intercooler.

to 2500rpm max boost with a custom intercooler. costing 2500 cash. not including install.

love it.
