Hi

I have a buildt H22A engine with Golden Eagle intake manifold.

Power goal is 400Whp.

The stock H22A come with a throttle body that is water heated from the coolant. It seems that it is thermostat controlled inside the throttle body.

I have searched HT and the reason for the water heating ppl come up with is to eliminate freezing of the valve/throttle body. (sticky valve)

My question is, what about non-OEM throttle bodys, dont they stick ? There is no heating on them as far I can see.

Can I expect HP gain with another non-OEM throttle body, any sugestions what i should get?


Thanks

 

a bigger TB will give u some pwer, and they shouldnt stick no matter what.

 

THe prelude throttle body has a fast idle thermo valve that connects to the bottom. coolant does run thru it but it can be eliminated. If you have a EMS you can tune you fast idle and everything down perfectly. I have blocked off my fast idle thermo valve and disconnected coolant flow from the IAC and FITV. I have never had freezing problems and i live in new england

 

Ok..

I will buy a BDL throttle body from Laskey and let the throttle body coolant go thru my water cooled turbo instead.

Thanks
