Intake interchange Q...

Recommended Posts

Hey, I was just wondering, does the EA82 intake manifold fit on the EA81 engine as well? Provided they are the "same" heads (like MPFI, Carbbed, etc.) I have heard yes, and some say they aren't sure... so I thought I would ask.

 

Thanks

There is a spider in the garage, but it's my sister's. I am getting one from phil though.....

 

I would assume that it would work, but I would need some heads or measurements to find out for sure like you were saying.

 

Thanks,

Rick

I really don't think the cam will be that big of an issue.The other good thing is that your brat is an '84....The turbo's came in 83-84 so I am thinking with the years being about the same we should get pretty lucky.

 

Here's my thinking:Turbo cam profile will be shorter duration for higher rpm power.

 

N/a cam will be longer duration for more torque.By how much I am not sure.Please correct me if I am wrong.

Turbo cams have less overlap than n/a cams, generally speaking. That's so less of the pressure gets bled off through the open exhaust valve.
