1g Throttle Body on 2g question

[ZigsGSX97]

Ok so I have a 1997 Eclipse AWD and i just got a 1g throttle body off a 92 talon. I got my intake manifold machine ported already so that's set at 60mm like my 1g throttle body. My problem is that my stock 2g elbow is still 52mm in diameter along with my fmic piping. What do you think I should do since I go from 52 mm piping to a 60mm TB? Get a 1g elbow?

The 2g throttle body elbow is bigger, so it would work better. This is why alot of people get a 2g throttle body elbow and put it on there 1g.

2g and 1g are POS, big restiction right there..... Get a custom 2.5" if you can ....

2g is better that 1g just because 1g input hole is smaller that 2g. 1g output is then bigger than 2g output .... 2g is 2 inch all the way (this is inside diameter)...
2.5" input and output is what are you looking for.....

Dejon Tool sells an upper intercooler pipe that replaces the whole 2G TB elbow and bolts right up to the throttle body. Maybe you should look into getting one of those?

I ported the lip of my 2G elbow right before the TB to match my 60mm TB. But 1/4" back its still is 52mm. So its a temporary fix until I upgrade my intercooler piping.

I have custom ic pipes made for me that are 2.5 inch so i can't buy that uic pipe. Is there any performance shop that sells a throttle body elbow at 2.5 inches?

Dave Brode was selling 2.5" throttle body elbows made out of steel. Check up on him if he still sells them

Stock 2G TB Elbow ported to 60m on the TB side works fine for me...

HKS makes a 2.5 inch elbow same as stock lenght and everything. My buddy has it on his 1G laser. Nice piece.

Heres a guy with one. http://www.ecanfix.com/~atdsm/chmdrm/

or Get these welded. The flange and tight radius 2.5 bend

Roadrace engineering also sells a 2.5" TB elbow also

Yeah, I think I'm just going to port the flange on the tb side of the elbow

You dont have to do that....it wont make any difference. Now I can see if the TB was smaller than the elbow and there was a ledge the compressed air woule be hitting, then I would port the TB but the elbow doesnt need it.
