Using Walbro 255. I would love to not have to go through the body contorting task of messing with the fuel pump again if I don't have to.

 

Chitoki wants you to spend a lot of money

 

329whp/213 trq is right in the mid/upper range of what I expect for 8psi on this set up, however im a little confused as to why your only seeing 8psi out of the 3.6 pulley. You should be netting closer to 10. Are you at sea level? If so, maybe you are getting some belt slip at the top end. Actually 213trq is pretty high for 8psi, but hp is closer, so that tells me you are likely getting belt slip, because max trq is made lower in the rpm range before belt will start to slip. So you will yield a normal trq number but less hp in that case. I bet you could be making closer to 10psi and 345whp with current pulley.

 

Not needed. And ID 725 will be enough, even if you had to bump up the fuel pressure a bit with an adj fpr. Those are good injectors. If you were running a NV1200 at full speed id tell you to get 1000cc.

 

You know how that boost bug is! Its how I do things, I went with high end support mods then when it came time for the smaller pulley, only needed a retune. I stock up on parts and such as it is.... you know the sellers around here, even OEM oil filters are mint and rare.

 

I get it, however short of the upgraded heat echanger, the OP has all the support mods he needs currently to max out a NV1000.
