OK so im now having second thoughts about my 12a half bridge port Engine or a 13B-REW single turbo

Just some pros and cons on each engine, this is a cruising/ track car.

I have the 12a already half bridgeported but worried that it wont be enough power and would rather sell it to somone who needs the housings, but also love the idea of a 12a, on second thought the 13b-rew stock is close to 300 hp.. and reliable..

so what do u guys think, also what could i get out of a diassembled 12a? in very good shape..

 

Also if choosen the 13b rew would be bought from jdm engine depot complete with tranny and ecu

 

if you're road racing the bridge NA motor is a better choice, imo

 

A stock FD engine is not close to 300hp, if you go single turbo on it you aren't going to be using the computer, and depending on the chassis, you may not really want to use the FD trans anyway.

Now, what I'd do, would be to sell the 12A bits and build a nice N/A engine out of the FD core. The 9.0 rotors would work fine (9.2 worked fine for Mazda for many years) and you can easily sell off the unused parts. One of which is the intake manifold... I held an FD intake in my hands and was shocked that any air at all could flow through that POS. Fortunately, there are aftermarket options available.

Bonus points for turbocharging is that it's quiet compared to an N/A. But the heat rejection problems suck.
