How hard to change turbo?

[adam 32]

cam aka boostmeister ran over 300rwhp on his car using a VG30, unsure of what boost levels he was running

[MrMayhem]

is it modified?

[adam 32]

not that i know of, no.

Cheers heaps guys

I think I might try and get a FMIC fitted and then chuck on the VG30 and a bigger pump.

That'll do me for the moment

boostmeister had tuned cam gears and s-afc and a few other thing I'm not sure about the 300 rwhp. on many other dyno's cause as we all know some dynos read higher than others.

I know for a fact the cg30 turbo is rated @ 300-320 hp @ the fly wheel it only has a 49 mm exhaust wheel.

but still they are a good turbo I do miss mine even though it was laggy.

laggy?

is the vg30 much laggier than the standard turbo?

is this correct?

just strapping on the vg30 and runnin it at 18psi aint gonna get u 300rwhp, theres so many other factors u gotta take into consideration!

[MrMayhem]

i still wanna see a std vg snail puff enough air to do it without considering the rest

400 plus from a vg turbo seems a lil optimistic anywhere except on the net

Shit yeah you are pulling out a roller bearing turbo (sorry im not sure about others but i have a vg30 nonbb) with small .48 or similar exhaust housing with tiny wheel now you will be upgrading to somthing with much larger exhaust iun comparison..

Im guessing you wont get full boost till 3500 does this sound about right? I had one on a CA18DET and it didnt give me full boost till about 3700rpm.

As for the other guys I mentioned 18psi as a ball park figure with other mods to acheive 300rwhp from an rb20...But as Inasnt said it is absolute max rating! Id be saving up a bit more and going for a HKS 2540 or the like if i was in your boat Jimih :burnout:

You still have to do cooler first and some engine management

[Guest INASNT]

if u want 2540 this guys sellin 2

mmmmmm a GT2540 would be nice .... I think I'll just have to stick with the VG30 for a while till I save up more money

I got the intercooler today ... now I just have to get it fitted.

That new fuel pump is loud!!

macka im sure you mean ball bearing
