On a tubular manifold there is a lot of separation between adjacent cylinders because of the longer tubes. This makes reversion very difficult, which is good for power. But you lose a little spool time on the turbo when you go with a tubular mani.

Equal length is the best to go with if you can afford it and you don't wanna spend a ton of money on the VET cams. I bought a set of VET cams to go in mine because the log manifold doesn't like overlap. The VET cams have only 13 degrees of overlap and about the same lift profile as the sr16ve cams. If you want a broad powerband then the VET cams would probably be best for efficiency.

I got a set of cams and will be trying them out in the next month or so. 16psi on my setup should make pretty close to 400whp if not more.

Stock cams and logs will make power, but you will completely negate any VE advantage in choosing the log mani UNLESS YOU CHANGE CAMS.

So, I say: Big power, tubular eq length with freeflowing turbine. Max street power, log mani, VET cams, and less laggy turbo.

Once you get that sorted out the VE should make amazing numbers. I guess I will have to find out! the last build made 265whp on 10psi and about 300whp when it was tuned. This time it should make well over that on 16psi.
