Found a good local deal. Would there be a benefit to getting a 60mm TB while running the stock turbo? I have a AEM SRI and MaxxFab 3inch O2 housing and 3inch S.E.E. I've also upped the boost to spike at 19 and hold 16 via wga & a mbc. Is this enough to make any use out of a bigger TB? I plan on getting a FMIC sometime in the near future, but hard pipes, honed/extruded/ported/whatever intake & exhaust/turbomanifold, and a bigger turbo/fuel computer are a ways out (ain't got the funds). What do you think?

 

60mm Throttle bodys are good for one thing and that is to leak

 

I appreciate the response, seeing how it is the only one, but it is rather vague. Is it a particular company that has been known to leak? This was a stock TB ported out to 60mm, so why would it have more of a chance of leaking? Please elaborate.....

 

I put a 62mm MpX throttlebody on my stock Stage 1. It didn't help and it seemed to hurt actually so I took it off. PSI told me something about a vacuum leak around the throttle plate but I don't see how it could leak. I only know it hurt my performance. I'm thinking with Stage 2 this thing might be great, but I'm a ways out from Stage 2, like you because of funds.

Doubt this helps much but it 2nds the possibility of vacuum problems and less performance. Check with PSI.

 

I've seen her on here since I posted this, guess she's not interested[>:]. I have read about issues with leaks, but that is nothing that a good seal wouldn't fix. The deal is too good to pass up. So I guess we will see. Swapping out the TB this weekend....
