how hard is it to do this, if it is possible, i had a look at the manifold and the biggest issue is the coolant hole being too far off.

also if i were to buy the LS jrsc manifold, will it bolt straight up to the m62 GSR blower?
TIA

 

I know the B16/typeR mani bolts up with a little fab work done. I do not know about the GSR mani though. The M62 will not bolt straight up to an LS manifold. I wish it did. You can make them fit with a bit of welding/cutting/drilling skills from what I understand. http://www.theoldone.com has an article on it.

 

yeah i read that one on that site. it seems like the gsr has a big difference on an LS compared to the itr/b16's.

 

The easiest way is to modify a B16 manifold to fit your ls block. There's a guy doing something very similar on the jrsc thread...check it out
