So I'm rebuilding a 12a turbo doing a semi pp ,and Bridgeport, and adding dowel pins cause I want to run n/a rotors...someone told me to run a 70a/r and a 96a/r hotside...
What turbo you think I should use...
It's gonna be a track/drift car, well let's just say a fun car lol

 

Gt40 70ar 1.15 hotside

 

na the 96 will be better for drifting. if you want it to lag a lil less. kinda sounds like you are just making the motor as big as you can and throwing alot of stuff at it with out finding out what you need for a power goal but ah what do i know

 

power goals?

 

A 96 with a full bridgeport, yes, but with a PP on top of that, it would seriously choke the flow higher up.

 

Do you need a turbo or already have one?

 

Also, with a full bridge and PP AND turbo, are you trying to drift with 1000 hp?

Just get a nice TII engine. Just a stock engine and turbo (with a higher stage TII turbo) will get you 400whp.

 

ok i plan to do a bridge port with a semi peripheral port not a full peripheral
i want anywhere from 300 to under 400hp
basically i want a build that pushes an easy 400 hp but i want to tune it down to 300 or anything uder 400 so it runs strong and is spooling quickly from low to high rpm's
did i make that clear?
its not like i can go do numerous amout of runs trying out different types of turbos ( a shop that allows this for the best set up would be amaising lol) but im not trying to buy one turbo then find out theres a nother turb that would run better, i know what i want but when it comes to turbo choices.

 

Quick question...how can you do a semi peripheral port?

 

why are you doing crazy porting for power levels EASILY attainable on stock ports?

you want one of these:

gt35r, t04s 60-1, or t04e 60trim. stock ports all will hit 350 easy. the 35r is more $$ but will err towards more power and faster spool.

The t04e will hit do the job too and be cheap. Streetport it if you're concerned about meeting your power goals.

 

just do a street port or a full bridge no point in going into all the trouble of doing weird PP's for 300-400hp lol...my buddy's bridge is making close to 200hp N/A, now he's got a turbo on it, can't wait to hear what its got lol

 

true your car is light enough . I would go street port with a S5 t2 turbo since you are using high compression rotors and make an adapter since you have to custom make the manifold for the 12a anyway to go turbo. boost the turbo 10psi and go drift and save your self $$$

 

S5 TII large street port with a hybrid T3/T4 . But really he can do just do a nice blowthru turbo setup on his 12a and make great power.

 

....nothing smaller

 

Epic turbo is epic, what's that off of, a freakin' ocean liner?

 

most likely, some of the turbos they use for there diesals is crazy!

 

"drift/track car"? That's an odd combination

 

not really, if he goes adjustable, its really not that different.

 

Adjustable what? Struts?

 

struts don't make up for the massive rear spring differences drifters usually run compared to racers.

 

I know. I was thinking that the set up between a track car and a drift car was completely different if they want to be competitive in either one...

 

right, and for the record I gathered that you understood that and others in this thread didn't.

/jacking

 

How long have you been working on car's? Your goals sound.... well, to be frank and somewhat polite.. "uneducated".

 

well im more familiar with n/a 13b's thats all
reading is different from doing, especially if you want the right set up, i just want to hear some of the peoples ideas heres my engine...

 

My suggestion is to spend lots of time reading in the 2nd gen section to see what kind of hp they're making and how they're making it. Granted, there are some differences making 400 hp with a 12A compared to a 13B but the principles are the same. If you want longevity from your engine, start with a TII block, preferably an S5, and go from there.
