I have a ls/vtec motor with 195whp on a mustang dyno. type R pistons with complete skunk2 stage 2 valvetrain ect.... I have a skunk2 intake manifild with a aem cold air intake. I want to know which throttle body is the best to use and which size. I have a stock integra ls one now.

Thnaks alot

 

STR is really nice and inexpensive should look into that..

 

I want to know if I should go with a 70mm or a 65mm

 

i think you should go with a 70mm

 

well considering that the plenum of the skunk2 manifold is only 64mm then going 70mm would be overkill. a ported b16/gs-r t/b that is 64/65mm will work to the best of your benifit. spend the extra money on getting your skunk manifold portmached to your head. -Jason

 

i agree. the 65mm might be in your best interest

 

65mm

 

its 1.8L so 65mm should be fine what is you useing now ?

 

I would def go 70 mm, and the inlet can be hogged out to fit it. So dont worry about not being able to match it. Just dremel it out.

Also, if u do decide to stick with a small tb i would just send your stocker to maxbore and he can bore it out to 64mm and its only $100.

If u wanna go bigger go 70mm

 

if youre making 195whp then go 70mm

 

Get a throttle body that is port matched to your intake manifold.

 

65mm will be fine. I made just over 200whp on my 1.8l and was using a 65mm.

 

rpm 70 to 72 mm t/b
I made 196 on 72mm t/b

that's right 70mm is too big and you might lose power 64mm will be alot better for your set up

 

i disagree, though u may lose a little low end, or the powerband might be shifted up a few hundred rpms Your not gonna lose power. Especially when the cars in motion.

 

yea i'd go 65 mm

what i was saying was you'll lose power using a 70mm tb compare to a 64mm tb the bigger the tb doesn't always work. 70mm throttle body works better with a 2.0L

YUP
i got some opinions from Javier@JG and Steve @OMNI-POWER
OEM bored T-body can support up to 230-WHP
i just sent my GSR throttle body to http://www.maxbore.com not too long ago and it went from a 60-MM to a 67-MM/64-MM tapered set up.
cant loose for $100-shipped

Check out my album in my signature and check my lil album section for my motor build up and i have before and after pix of how nasty my throttle body was before i sent it to jorge@max bore and u can see the after shots and beautiful it came back.

 

I'm running a 190whp LSVTEC (dynojet)

I've got an ITR IM and a B16 TB, would it be worth it to upgrade? How much HP does a bigger TB usually make?

70mm is too big.. your right that you will lose power low end... and the curve iwll shift up, but not just a few hundred rpms.. its ognna probably move upa couple thousand rpms, probably to high for you cam set up... it will simply be over kill and you will most likely lose power, your tope end might be the same or even a tiny bit higher but you middle range is going to suffer big time.

 

62-65mm for 1.8L's 66-70mm for 2.0L's

very little. its usually throttle response that is improved.
