Well since many of the parts are from a member on this forum I figured I would throw up what's going on.
After 3 months and 3 engines in the wifes 86 MR2 (can't get rid of it -- too much sentimental value.... it was a graduation gift for my wife back in like 2005... then because of that when we got married our cake was an 'MR2 Cake'... anyways) and unable to find any importer locally who has a 16V 4age.... I came across Bill Strongs page regarding the MK1.22 build.
It doesn't look overly difficult but it also isn't going to be my first swap. In the "member MR2's" page you can also find my 87 hardtop / ae101 gze/megasquirted car (which I have still yet to find a 4agze that was megasquirted with the SC12 before this one.... I dare to say it was original).
The most difficult part will be mounting it into the car. I'm not entirely set on how this will go but only time will tell. So far I decided to do this on Sunday... now it's Thursday... the AW11 has started to come apart and my parts collecting has begun.
So far I have from a 91 MR2:
91 5SFE (complete as pulled, running), S54, portions of mounts
Axles, various electronic bits, starter, alternator
Various other pieces
I have 'on the way' a 91 Harness, ECU, and coolant fill pipe
I will be ordering one of the ebay headers. I will also probably have to order the coolant hoses on rockauto as Napa had a very small selection.... we will see.
I pulled the valve cover today on the 5s to change the gasket & spark plug tube seals. The head internally looks cleaner than the outside.... probably thanks to the lower revving engine. I also replaced the o-ring seal on the dizzy... though I think it's the inner seal that's leaking as there's signs of oil inside the cap itself. Oddly enough I have a spare 5sfe dizzy and it might not have the leak... I will have to look one of these days.
The AW11 has started to come apart... right now once axles & exhaust come out the engine is ready to come out. The unfortunate part is that I had painstakingly put a large amount of effort into fixing the alternator wiring and in doing so completely changing a large portion of the 4age harness. You'll see what it looks like below.
Photos aren't exciting by any means....
The car...
The AW11 engine as it sits now:
The wiring was rerouted under the intake manifold. Yes that's a smallport head. This was a JDM bigport block. Smallport head was cut 10 thou, new valve guide seals, and bigport cams. There were zero signs in this setup that t-vis was missing and above 4k you could tell it was a much better setup. Oh well, such is life.
The 5s as it sits....
