B18C turbo

^^ he makes a good argument.

Limbo, I will keep the offer in mind, thanks.

might have to enquire on how much it would cost to upgrade the rear and see how that goes, would be an interesting comparison. I think that I am still more of a mind to just change the whole thing though.

I am running a 2.5 inch exhaust all the way through at the moment.

If you do swap to a bigger turbo and decide to sell your disco potato shoot me a PM

true i forgot to factor in the comp ratio but the Type R and the VTiR has different comp ratios right? i am not to sure?

[Limbo]

yeah type R is quite abit higher

Im currently using a gt30 in a b18c blacktop, it spools at about 2100rpm.
Being as i've never tried a t28 cant say which is better, but it's currently making 216hp at 7psi.

P.s. Arent the T28 and T3 flanges different may need an adapter or new manifold?

[Limbo]

dam that's a quick spool for a gt30 wat rear are you running?

yeah the gt28 & gt3 have different flanges

[swooshek]

I think it's a .86 but got a really short log manifold so that may help.

[Limbo]

i dun think it helps that much, unless your like not running an intercooler?
Even luke with his log doesn't spool that fast. He doesn't hit full boost until 4.5k rpm

[FastFwd]

dam makes me think if i should have got the gt30 instead of my gt2871r when i did my last rebuild/upgrade.

[Limbo]

yeah but i would have thought the GT30 would have been a later spool.
Maybe he's got a small rear housing

[mooshie]

The GT3071r is available in a T28 housing, it is the largest you can go before going up to the T3 style.

swooshek: 2100 is a very low spool. Is that when it starts up? mine currently starts to spool up at about that and is full boost by about 3500rpm.

you dont happen to have a dyno print out do you?
