12a turbo bridgy
hey guys i am debating b/w a peripheral or a turbo bridgy? is gonna be for pure racing, no street so which one is better for a track car, considering reliability in the track, allowing for a rebuild every year 1/2 to 2 years. considering the turbo running at 10 psi. which one would produce more power? let me know on cost as well, i am a budget racer. thanks in advance

I'm not a racer, but just from the top I can say if your on a budget, don't go turbo. With turbo your into alot more money and maintanance, more parts and etc. to break, more money to replace etc.

a big bridge port will be plenty with supporting mods.

If you are on a budget neither choice is for you. Doing a street port and driving an all motor street port is the only way to go. If you have a good chunk of change, you can street port and turbo. That will run around 2-3k if you do all the work yourself. A P-Port will be that much alone in housings, assuming you can find them somewhere. A bridge port turbo setup will run the same as the street ported setup assuming you still do all the work yourself, but the engine will require rebuilding far more frequently than a street port.
If you are wanting a race car then you also need to consider how the car is going to react on corners and how the power comes on. That will require tons of research on what turbo to use and how the power is going to come on in accordance to the port work you have as well. Also, something to consider, all motor vehicles behave far better on track situations than turbocharged applications due to boost creep as opposed to a fluid power band. It sounds to me that you need to do a lot more research on how you want the car to behave rather than just asking us. A P-Ported engine is far better for racing than a turbocharged bridgeport even though the turbo bridge will make more power (assuming you get a good sized turbo and not some dinky stock DSM turbo or something.) |

Most reliable roadrace option I am aware of is a stockport 20B single turbo ;)

A stock 12A might put about 80-90 hp to the wheels. The last 12A bridge that I ported for a customer made 175 rwhp with a 45 Mikuni and low timing. Customer had about 2 grand in that setup. After break in, the owner wanted to turbo it. He went with a GT35R. I setup the turbo with the Mikuni blowthrough. That added about another grand. It dynoed almost 350 rwhp at 10 psi. I would never drive that turbo setup on a track. Tottally too much horsepower for a first gen. When it was all motor, maybe. Do alot of researching before you decide on what kind of setup you want.
