What throttle body should i choose?

[supermario300hp]

Hey guys...just looking for something else to put on the car before i install dsmlink.... I was wondering if anyone had suggestions on upgraded throttle bodies? Which ones are good? Are they even worth the money? and what type of performance gains should i be expecting?

I have 2.3 built motor, vrsf fmic, afpr, thermal exhaust, 3inch dp, and open dump O2 housing, also have 20g, 1000cc injectors, and dsmlink all on the way.

any advice would be much appreciated thanks.

1g N/A TB or any other larger throttle body on the classifieds.

you could always go the Q45 throttle body route. often times under a 100 dollars on nissan/infiniti forums

Aren't the Q45's a pain to install?

 

[mustard95tsi]

as long as you read up it shouldn't be hard. I've seen plenty of threads regarding the installation process.

 

[renovatdkitchen]

That's true. But if OP is planning on keeping his 20g, a 1G TB will work well and his wallet won't break a sweat.

You aren't going to be installing a 90mm throttle body on the stock manifold without a decent amount of fabrication. I'd stick with a stock 1g throttle body. IF is plenty for your setup. Spend the money on something else.

couldn't have said it better. Wish I listed to that bit of advise before I started.

^^^^this

If you fabricate your own IC piping there is no elbow required, just another coupler on the TB. More than enough flow for a 20g.

There's no point in getting any part that way out flows other parts of your build. It's just burning money at that point unless you have a set path your following.

Has anyone used the BBK throttle body? I was considering getting that one,but don't know anyone who's used it.

i went with the 1g turbo tb (92) and love it noticeable power gain just with the swap alone and it will take a long time to actually max out capabilities.

Agreed. OEM 91-94 1g turbo TB all the way..

Running a 1g TB here aswell.

Bbk throttle bodies are good. Bbk makes good stuff. I know it's a different car but I had bbk stuff all over my mustang including a throttle body.

What is the difference between a 1g Turbo and NA TB?
Should be the same diameter

 

[DSMnOOb00]

I'm running the 1g 94 throttle body, it's 60mm I believe. Just make sure to port match your manifold.

What exactly is required to run a 1g TB on a 2g with EGR and all related parts?
Do I have to remove any of that crap or is it just a direct swap with same vacuum ports?

 

[DSMnOOb00]

It's pretty much a direct swap, although you need to also take the two sensors from your 2g TB, they look exactly the same on the 1g TB but they are different.

Although in the 1g TB you'll have an extra vacuum port you'll need to cap off, it's the port that's angled away from the rest. That's about it, you should port match you intake manifold too since you'll have a bigger TB and the manifold is sized for the stock TB.
