i have an 85 mr2 its bone stock and it has a 4a-ge and i want to swap the engine but i have no clue with what or what i want to do can some one help me out on what to do thanks.... steve
Changed your mind? You might check the parts forum here or Ebay--they occasionally come up for sale. You could supercharge your 4age---if you can round up the right 4agze parts. I'm still wondering myself how long such an engine would last.BethanyMark1 said:hey would u guys know where i can find a wiring harnes and an ecu for a 20 valve well if anything just hit me back later guys
how do you know it is a serious problem? from that description it could easily be air in the cooling system or a stuck thermostat, and a minor oil leak that simply requires a new gasket (distributor, oil pan, etc...). i just wouldn't want you to misdiagnose a perfectly fine engine. what does the coolant look like in the reservoir?BethanyMark1 said:i know that my 4age will not last cause first it have on oil leek and the motor start to over heat.
I'm not picking you out of the crowd ITA-MR2 but do you know who said this? I'm interested in doing this swap (toyotaspeed90 just finished his) but I'd really like to know why everyone says this... Is this just an assumption or it there some evidence that it is really the case? I've heard that the C series transaxles will fail when mated to a GZE (esp a JDM GZE)... But I have not heard this from someone it has actually happened to so I am a bit skeptical... I'm thinking of running the tranny I have with a GZE since it is quite a bit lighter (possibly weaker too). All I want to know is if this is simply an assumption or not. I guess there is ultmately only one way to find out for sure... Those GZEs sure to have a lot of torque in the low end so I imagine if it did fail it could be quite and exciting event.The GZE will, however, bolt up to the stock transmission - it's just not quite as strong as the S/C transmissions.
When you put the new coolant in, did you bleed the cooling system? If the cooling system is not bled properly and air stays in the system it can cause all kinds of problems.BethanyMark1 said:it looks brown but when i took it out it had like balls of something in there and i put new coolant in and it still over heats. well the oil leak is easy but i just don't want my car to over heat.the leak is behide the distributer on o ring as they call it i think.. and the hard part is trying to get the parts i have not a clue where to get a kit for my supercharger for my car if u can help me out the i would love to keep my car but i want to boost like hell and i don't think that my 4age can't take that kind of boost u know..well hope to hear from u soon later
Who said this?? I did, and I'll stand behind it 100%. I did not say it would fail - I said it was weaker. The shaft diameters in the transmission are smaller, as are the gear faces. Period. I DID NOT say it would fail. It will ultimately fail at a lower torque pass-through than the E-5x - but unless you abuse the hell out of it, it should do fine mated to an engine with anything less than 150 Ft/lb of torque. And the ultimate limiting factor is peak torque - not peak HP.MR2 VRI said:I'm not picking you out of the crowd ITA-MR2 but do you know who said this? . . .

Hmmm... I guess I just assume that weaker means it will fail... Anyway, I've heard the same thing from about 8 different people so I was just wondering. Coming from you it means more since I imagine you have had a great deal of time to play with transmissions, etc. I think I'm going to stick to my C series and see how it does... It will be a little cheaper (if it doesn't break) to do the swap that way. Have you played with the gearing at all in your car? One of my other thoughts was to try and change the ratios a little bit... I have a bad syncro in 2nd gear and I was going to fix that at the very least when I do this swap.Who said this??

I have the wiring harness, if you still want to do that...someone I know wants it, but they can be flaky, so let me know...BethanyMark1 said:hey would u guys know where i can find a wiring harnes and an ecu for a 20 valve well if anything just hit me back later guys
The race car has a non-original final drive (ring and pinion) ratio. To the best of my knowledge, there were two alternate gearsets available for the C-50/52 - both close ratio, and both expensive (if even still available):MR2 VRI said:Have you played with the gearing at all in your car?
