have searched and searched and found nothing but i am planning on running a b18b with a GT2560R with 7psi and was just wonder what i can expect in terms on power? Also when can expect the turbo spool??
i forgot to add that i will be getting S300 and skunk2 intake manifold

thank you in advance

 

It spools pretty fast on a D series... I've got 12 psi at 3000-3500 rpms.
I think its gonna run out of steam on you though....

 

I'd say about 230-40 to the wheels with the IM and depending on how its tuned.

Have you done a leakdown or compression test on motor to ensure that it's healthy before you start?

 

why such a small turbo?

The dude in the post above said 12 and he has 237 at 12 psi.

I would almost say closer to 200 or so, but I really have no idea.

edit: misread post. thought op was on a sohc as well. around 230 or so sounds pretty right. It is a small turbo though... My friend had a lot of trouble getting his anywhere past 220 or so at around 12 psi but this was on a mazda.. Just not a very efficient turbo.

Lol.

It was just my guess because boilermaker said he was at 12 psi.

I figured a better flowing IM and a nice tune might make up for a PSI or two.

And he said his was on a D, so theoretically, this guy should make up that power with the B18

It's my estimate,and you are right, nobody will know until the tune comes

 

just a good DD turbo

 

it may be a good DD turbo, but you can safely run more boost than 7psi. Get a GM3bar map sensor and get tuned on 15psi (or something higher than 7)....as long as you're not pushing past the 350whp range (which will be near impossible w/ that turbo on pump gas) you're safe.

yeah 15psi is out of the effecieny range of that turbo. also i don;t really what to get a bigger turbo since the 2560 is so damn cheap for dual BB
