Howdy;

Posting this on Pirate as well a TTORA.

Posted this in newbie; but probably is more tech related than "can I put beadlocks on my 10 speed?" (You cant; I searched the FAQ.. )



I just picked up a totally rust free 86 4Runner; 22RE; totally bone stock and un-molested. Really a great score.. I swear I looked at about 10 1st gens all mostly junk or whored out..

PO snapped a timing chain a few months ago and did a total rebuild. I purchased it with supposedly less than a 100 miles on the rebuild.

I will post later (On a Tuesday of course) a symptom and fix for all of the issues I am coming across. (the PO was not having a good day doing this rebuild; install or tuning.. ) I am going to split all of the issues I am resolving and post them up (Some are in the FAQ but a few were not)

So; my question today is:

Early EFI to late EFI swap; in this case the intake manifold. I have the upper intake from a 90 22RE as a spare but no lower. I am not planning on swapping the entire EFI setup; just the upper half of the intake.

1. I have read that there is a performance improvement. Does anyone have real experience in this swap?
2. Is the lower intake the same for a early and a late? (Discounting injectors; looking at it from a performance standpoint)
3. Cold start idle air bypass (Air Valve). These are different designs from a 86 to a 90. Any one have any issues in swapping to the 90 style? It looks like it takes up much less space.

Thanx..

sounds like it would work

1) The intake has less restriction than the early model - you can tell just by looking into the intake itself. Practical improvement personally? I changed a bunch of other things at the same time so I can't tell you. I've read most people see better throttle response.

2) Yes, you can swap the upper only.

3) This is the area of difficulty, you can probably do it either way.. Here's a post that will help:

Thanx;

I am headed to the shop now. I will be installing the 90 late model. Need to source a few hoses to get the coolant where it needs to be.

How is your Runner coming along? Get your E-Locker installed? Still have the spare Runner top?

Have a good holiday;
