im gettin a jg edelbrock victor x. im going boost. trying to hit 500whp. i want to get a bigger throttle body. which one is good bbk 70mm or str 70mm. i want something that will bolt right up. no big modification. i searched some and didnt really find much. let me know.

 

those str tb's will bolt up just fine, only thing you might need to modify is the tb gasket.

 

anyone use bbk 70mm

 

Why do you want a bigger throttle body?

 

i used a stock throttle body but bored out

you could do that too, send your tb to maxbore thats what i'm gonna do to my gsr

 

What's wrong with the factory throttle body? The turbo is creating positive pressure.. the intake manifold sees the same amount of pressure as the piping before the TB. These aren't naturally aspirated cars...

 

so having the tb bored out doesn't really do **** then ?

cotney made 800whp on stock tb. If you do get a tb STR is no longer around, its now http://www.bdlind.com (BDL).

Well it adds an additional item to your mod list...

And cars with bored out TBs etc seem to have lots of idle problems and stuff... so it can "do ****"... just not anything beneficial. Just one more thing that can break / mess up.

 

but what if you have a big intake manifold like the victor X you'd need a larger mm tb to fit it properly correct ? it wouldn't be smart to use an oem gsr on a victor X, or am i wrong by saying that

There's no reason to go any larger than your charge pipe diameter.

Did a test of that on a civic, with an edelbrock turbo kit. The charge pipe diameter is about the same as the stock 56mm of the civic throttle body. Putting on a 62mm throttle body did nothing to the power output.

 

stock ITR TB is 3inches.
Worked great for me.

BTW i had it on a JG also

 

hmmmm interesting.

 

so my stock gsr throttle body will bolt right up to the victor x

 

yes it will bolt up

 

d16 one will bolt right up

what exactlly you do to the t/b gasket ?

 

make the bore of the throttle opening slightly larger so the butterfly can open through it

did it interfear with any of the other ports on the t/b gasket when you ported it how big did you go asking cause im about 75 mm on my gasket now and im having to cut into some of the ports on the gasket wich mite cause a vac leak

 

U also have to think how big your intercooler piping is, because thats will you will lose power going from a 2.25in pipe to 70mm which i think is like 2.5in maybie a little more?

i ported matched my aebs intake manifold and put a str(70) to it, the throttle responce was nicer and i gained like 5hp but thats on stock block b16 turbo.
