Your not going to find to many because not many people have done it , and of the few that did not many lasted long.

You should be using a 2g transmission, the 1g trans only has 1 mount on it and the 2g has 3 and the speed sensor is different on the 1g trans so with a 2g ecu your spedo wont work. Your going to be kind of on your own if you attempt the swap because there aren't any real successful ones done that you could use as a guide or get advice from. There are more successful swaps of EVO VIII engines into 2GNTs than 4g63s.
 
I think you need to do a bit of searching. Even getting the 2G cradle the 1G transmission will not work. The 2G tranny has the tourqe mount attachments where the 1G does not.

If you realy want to bolt a 4G63 into it you might consider a EVO 8 or 9 and a 3G spider transmission. at least then they are facing the same direction of the 420A

But Man you are opening a can of wormsOMG.
 
You sound quite determined to make it work, which may be your downfall. Listen to the advice people give, keep in mind that this isn't our first rodeo.

Have you ever noticed, they make a version of your car that comes with a 4g63 from the factory.:thumb: So whats the point when you can just buy one that is already done? I guarantee the one from the factory will have less problems that your hack job. Prove me wrong. Do it...

Don't tell me you can't afford one, thats bullshit. 2g gst's go for $3500 all day long, hell I paid $300 for my 1g and its awd. Go collect some change from the couch cushions, eat some ramen and save yourself from a lot of headache.
 
seeing how it's your first post I have no clue on how much you know about swaps and dsms, but I must say if you just payed it off why in the world would you chop up your car. go find atleast a rearended 2g gs/rs and attempt the swap using that not your just paid off dsm. good luck there has been 1 dsm that I have seen with the swap guy finished ran it for maybe 50-100 miles then attempted to sell it on ebay and ended up parting it all out cause it never ran right. I hope you actually do it but do a write up so others can follow. good luck.
 
Its hard not being turbo.....Isn't it.......With the money you'll spend in getting custom fabrication you could buy an awd shell. Then sell your car and put that money into your motor or in a bank account for when things go wrong. I'm a hater though, you could be like defiant and do it anyways and then forever laugh at people (be nice to me). However, I'm sure he'll let you know real soon how that is never possible. Anyways, be my inspiration do the swap but don't do anything to permanently damage the value of your now paid off car for when it doesn't work how you want it.
 
Build up the 420A and turbo charge it. You would spend less money and time doing this than you would to do a 4g63t swap. Everything is different. From the tranny mount points to the wiring harness and ECU location. You might as well build a race car from the ground up. Just get some Wisco pistons, Eagle rods, and a turbo kit then boost the piss out of that 420a. I used to have a 98 GS that was making 300hp at 16psi with this setup. If you really want power I would just sell the car and get a GS-T or GSX.
 
my buddy is selling his 95 awd shell for like $600 this would be the way to go just buy a shell
 
Either way... don't go ruining a perfectly good GS, or a perfectly good GS-T or GSX shell.
