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.

woudent a big bridge port put more stress on the engine parts since its power is up in the 6000 rpms rather than a bridgeport with a turbo which would produce the same power with less strain on components?

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.)

no i understand that if i was going turbo i would need to correctly match the turbo and i would need a new turbo and a dam good size one as well. i just wanted to know, what you said, an N/a is better on track because of response and stuff, although the turbo makes more power. and thats what i wanted to know about p ports, how much they run, i had heard they were expensive as hell but just wanted to know around what ball park. i think the best idea now would be then to just b-port n/a but prep internals to hold for boost, use it like that and spend more time researching which turbo would work best for my application and on the next rebuild of the engine then i could do turbo since most of the internals would be in good condition still unless something catastrophic happens, hope not.

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

i wont argue with that, i defenitly would not mind a 20b, but lets just say i cant afford that engine right now,or the swap. Later, its a possibility, but now i have to make do with what i have.

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.
