yea i'm still working on my project ka-t and i'm running into a current problem.
my engine has a huge port and polish job and is making low compression due to the stock throttle body and maff(needs 2 be bigger).
i was wondering if any 1 has used a q45 throttle body or some thing better?(does it fit?)
1. will the q45 bolt right up??
2. is theres a better design or product can some 1 direct me how to get it?
3. any 1 who has tried this plz reply?or any bright ideas would help.

 

no sir it will not bolt right up the diameter exceed that of an stock manifold, you would need to install some kinda adapter plate. its better to just create an manifold from scratch or Tig weld the Q45 TB to the intake manifold after you port match as much as you can.

 

I think you might be able to by weld-on adapter plates on ebay so you can run the Q45 TB on a Stock KA Manifold. I remember seeing them a while back. Or you would always have a machine shop fab one up,etc.

 

just get an adapter plate and weld that on. or go with big games idea.

 

hmm seems like q45 needs an adapter plate . thnx
now does any body know if any other kinda of throttle body will fit? or possibly if theres an after market one?

 

bro the TB alone is not going to make that much of a difference. if you have an stock plenum it can only take but so much air in at a time.

 

port that ***** or whip-up a custom intake mani, bling bling.
or yeah, you can just weld the adapter on like Airman Jackson said.
