'86 EA82 SPFI Block Swap
Posted 29 February 2012 - 06:17 PM
My '86 wagon has a stock carbed hitachi engine, and its on its way out.
I'd like to go through and just reseal the engine and retune the carb, but if I'm going through the trouble I'd like to make improvements while I'm at it.
I tried some searching and didn't come up with much.
My question is:
If I were to swap in a spfi longblock (higher compression) all I have to do is use the disty from the carbed engine, and the intake manifold from the carbed engine. Correct?
I'm also planning to ditch the hitachi carb and put a weber in its place.
Let me know if I am forgetting anything.
Thanks in advance.

set the timing about 10 deg higher and open up the exhaust.

When I swap in the SPFI longblock, wont the asv be deleted in the progress with the old engine anyway?
Or can I not run the SPFI heads with the carbed intake manifold?
I just looked under both my SPFI EA82s and the heads look exactly the same as carbed heads, they just have the (would be) ASV ports already blocked off.
Glad I'm asking questions now and not later, staring at a problem.

What would you recomend to "open up" the exaust? Cherry bomb? Straight pipe?
