ill be changing my 4agze for a later spec ae101 4agze in my mr2.
i dont suppose anyone has done this swap allready and has a wiring diagram?? many thanks

Wouldnt it be just a straight swap over? just interchanging between engines as need be?

the early one has an afm where as the later ones use map sensors. i think this will be the main difficulty.

If you're just replacing a blown motor with a good one, just swap the short blocks over. Saves having to fiddle with ECU's and what have you.

the engines fine, the 101 just has 165 bhp rather than 145.

yes, but the reason WHY it has 165 bhp (tui ad) is why you will have difficulty.

what is it that gives it the extra hp as i believe the block is the same? perhaps i can just swap certain parts?

higher static compression ratio
smallport head
smaller s/c pulley

Different ECU. There is a rumour that AE92 MAP ECU is the best one (as in no power loss after ~5500rpm, in AE101).

by **mart1975** » Tue Dec 05, 2006 9:56 am

so basically apart from the rumoured gain with the map sensor i should still see a 20 hp gain by using my ecu, afm etc on the later block?

can i buy your other 4agze?

My MR2 has an AE101 engine, using the aw11 distributor ecu and AFM, runs just fine. Essentially the same engine just different electronics. Easy swap, I don't know if it would be worth the effort unless your old motor was stuffed though.

if your just after more power, why not just fit a larger pulley kit to your existing setup? the afm version pulls like a school boy to redline, no 5500 drop off.

yeap, and upgrading to a water/air cooler will make it better again.

bzg, im in england matey so its not worth the shipping costs.

i already have the larger pulley so i should be running 175 ish, thing is if i fit the 165-170 bhp engine along with the pulley i may be seeing 195 which is a very cheap way of getting 20 extra horses considering the other options.
if i fit the original dizzy, ecu etc will i still see these gains?
if so surely its well worth it?

ok so looks like in order to achieve this im going to need to use all the electrics with the new engine.
i just need to know how to wire this in or get a copy of both engine wiring diagrams so i can work it out, anyone have these?

by **big_boy** » Thu Dec 14, 2006 5:09 pm

just take the looms as well they both go in to the car harness useing the same plug & pins so u just swap motor with ecu & loom then plug the new motor`s loom in to the car`s harness
