Alright. I decided I'm gonna do the full swap from the 4g64 to a 4g63t. I recently found a 90 Talon TSi AWD that I can pick up. Brand new ECU and the motor was redone about 45K miles ago. Turbo was also replaced around the same time. The only thing is I heard that the 90 Talons had reliability issues. Can anyone confirm or deny this? Would this be a good motor to swap or should I find a 2g 63t?

Another question concerning the AWD(Since I have an entire donor car) would that be a possible switch or would I need a new suspension setup?

The AWD from a 1st gen will not work on a 2g. You will need 2g parts for that.

Are you buying a perfectly good 1st gen and detroying it? That would make me very very angry.

It would be much easier for you to swap in a 2g engine. They are easy as hell to find because tons of people are swapping 1st gen blocks in their 2Gs. You can pick up a whole 2g longblock for pretty cheap these days.

You will also need the wiring harness from a 2g, ECU, motor mounts (I think), tranny, possibly axles, etc etc. It is a very involved process.

1st gen electronics will not work either. You will need a 2g ECU to make your car work.

I'm doing the work on a 98 Eclipse Spyder with the 4G64 NA motor. The 4G63T motor will swap right in(Unless the motor mounts from a 1G were different then the 2g same engine). Everything else will bolt right in. Shouldn't be a hard swap at all. Just wasn't sure if the 1g stuff would work.

your going to have a problem with the wiring. you will need to re-wire the whole car if you want to use that new 90 ecu, or you need to buy a 95+ turbo ecu. the easiest thing to do would be to swap a 7bolt engine in. you can get them for $500 for a good engine with a head(atleast where i live) i think it would be easier to find a junkyard and buy a front clip off of a 2g turbo.

yeah in short, no, it would not be a good motor---you're also going to have tranny issues because jeff said the AWD components won't swap--so now you have to find a 2g FWD tranny. I'd look for a front clip....

I'm wondering why you are so quick to not use the 4g64 block??

From the information I collected the 4g63T motor is better balanced to handle the higher revs. That and I have access to alot of tools and manpower but no one I know could port match the heads and I'm not sure where I could even send it to have it done or how much it would cost.

the 4g63 isn't a bad idea, it'd just be a better idea to find one from a 2g--save alot of hassle

The engine mounts on the 1g engine and 2g engine are different. The 1g block has 3 mounts, leaving the tranny with one. 2G trannies have 3 mounts and the block only has 1. You will be much better off going with a 2g 7 bolt longblock and tranny, as well as the 2g ECU, wiring, etc. It is much more complex than you think it is from what I gather.

After much internet looking, All I found for a motor is a 4G63T front clip with the motor for a 1g. I checked the junkyards in my area here and he said that kind of motor is a rare find around here. Apprently DSM's get stripped quick. (Darn parts junkies). Other then that the 90 Tason TSi AWD has been the only thing that came along. The Ideal thing I'd like is a moderatly damaged Eclipse GSX as a donor car for everything I'd like to do.(AWD would be a blast).


Just out of curiousity anybody here around the NE PA area?

And yes I know the AWD switch is going to be a bitch and a half.
