Project86- My first (and probably not the last) Rebuild

[TitaniumTT]

If all you're looking for is around 300RWHP then I would actually consider using a BNR hyrbrid. It'll be almost a bolt on affair and then it leaves room to grow with a full aftermarket Garret and a custom manifold. The Turblown and A-Spec mani's are works of art and with a properly sized turbo, the reposnse can be made to be much better than a BNR single. Just something to think about.

If you start with the twins and then go single, depending on the route you take, there will be a TON of unneccessary crap there that you will have paid good money for that will just end up in the trash or trying to sell. So, I would think long and hard about what you want out of this car before deciding on which route you want to take.

If response is the ultimate goal - twins without a doubt but it will cost more in the long run.

If 300RWHP is the goal and you don't mind waiting a little for the power, I would really consider a small sized single, full ball bearing, and really concentrate on doing you're homework on manifold sizing and exhuast porting. Think Pineapple EP2A port. Seems to spool the twins ~ 1krpm earlier with my setup. Which is pretty sick.
