Thread: L36 Throttle on L67

Would an L36 Throttle be able to work on a L67 and run right when doing an engine swap?

the throttle body will fit yes, both the 3 bolt i believe. but not sure if they are the same size

there will be a large step from throttle body to the blower. i would NOT recommend it. get an L67 throttle body, they are not expensive at all.

You can buy the l67 tb for like $30.

I got one if you need one

yes it would work but why would you want to the l36 tb inlet is smaller just get a l67 tb and do it right u can get one cheap listen to bio

Some of the people running an L36 TB with the SSM90 kit have problems on a cold start. Using an L67 TB seems to fix it.

If you're trying to save tuning, don't bother. Too much other stuff needs changed.

And Ron Vogel ran 13.1s on ported exhaust manifolds and a 2.8" pulley. Just because it can be done doesn't mean that it should. If it's a ZZP ported TB, it's been bored out with a bigger throttle plate, too, so it's not really a fair comparison.

Thanks guys. Its juts that i recently had an engine swap from an l36 to a l67 2004 impala ss engine/tranny. Receive the car tuesday from the shop and they told me they used my old l36 throttle because they could not locate an l67 throttle in time. I seen a gtp at the junkyard last week with the complete engine still in tact. Would that gtp throttle work well with my impala? Thanks again.

I assume you're using the L67 computer, did the shop tune it for the L36 TB? If not, the thing is going to run like crap, since the MAF calibration would be different. You can't just switch back and forth without changing the calibration.

All 99+ L67 TBs were the same AFAIK, no matter what car they came out of.

Yes, all 97-98's had the bar in the middle of the TB and the '99-'03s were the ones to get...

We all know you meant it

if you want a good ported throttle body you get the 97/98, port it, and put a 99+ MAF in it.
