im looking to boost my 1.8L civic a but, and my research seems to say that a GT2560 with .60 A/R would be a good choice for a 7 lb boost.

Anyone doing this? I sure would like to hear. I am also open to other ideas.. Its a daily driver so I am only look for some slight extra help passing on the highway...

Boost would be instant and a lot of fun on the low end. I'm not sure if you'd choke on the top end though, I think you may have some issues maintaining boost pressure on higher RPMs, would probably require some tweaking on the wastegate to get it right.

For a B16 I wouldn't worry quite as much about this, but for a 1.8 I'd suggest bumping up at least to a GT2860. Is this an LS motor or VTEC?

 

I had a GT560R on my Stock LS and it was great. Maxxed out at 300whp/300trq and 21 lbs.

 

I'm curious what impact an LS Vs. VTEC head would have on the top end for this turbo, with how small the exhaust profile is. Less head flow may almost be a good thing.

 

It will be better if you tell us your goals and budget.
For example im not sure if youll find a cast iron t28 manifold for stock engine setup.

 

The turbo would just make the same power with less boost and would fall off more in the upper rpm range.

 

It is a V-TEC R18A. I had looked at that 2860 too....

thanks.
