if you know what parts and ---- is wrong. Just switch it and stop telling us.

I know most of the parts that are wrong, but I've never done a 1g to 2 g swap...i.e. OBD1 - OBD2 dsm swap...so what else has to be done. Every time I've posted I've asked for documentation or a write up...not why it isn't working...I appreciate you reading and posting, but honestly read the whole thing instead of stating the obvious.

First off you NEED to have:

FWD 2g turbo ECU
1g turbo CAS
unplug the damn TPS (otherwise you have a random misfire code and it will run like -------)
2g turbo MAS




these are thing that NEED to happen. I'm not suggesting them. Then check over the wiring. Read this damn article and follow it. http://www.magnusmotorsports.com/article_1g2g.htm


Good luck.

Just wondering, what engine mounts are being used?

You use all the 2g 4g63 motor mounts. The lower timing gear cover has to be cut a bit, but that is silly little "problem"

try to use as much of the 2g gs-t parts u can. you shoulda jus got a 2g gs-t motor/harness/ecu and you coulda called it a day. basically u gotta convert it to 2nd gen everything since ur using stock management. not positive if the 2g harness can jus be put on the 1st gen. dont kno if all the sensors are the same but thats what u have to pretty much achieve. coulda reduced most of ur problems with the proper motor for ur generation car. it has nothing to do with "na to turbo swap". that hardly means ----... its like any other u jus need the ecu n so forth. match his setup to be like yours. 2nd gen engine harness n blah blah blah. good luck =x

I am just looking for a write up on the turbo swap.

I've already redone all the vacuum and charge lines to teh best I can, put in a new re-circ valve and cleaned up the hoses.

That is a list of reasons why the car doesn't run right, why are you asking us what is wrong, you need to change all of those things

Why would he want to waste his time putting in a 2g turbo motor in that? ::)
If you knew anything about DSM's, you'd know the 2g 4g63 has an issue with crankwalking. It has been blown a bit outta proporsion if you ask me, but the risk is still there enough that I wouldn't waste my time and money on putting one in when I could have just put in a 1g 6-bolt block instead. The 6 bolt swap is very commonly done by 2g owners.

If you don't know what ur talking about, then just... :-X

Just to clarify this is replacing the 420 neon engine right? I wasn't aware that the engine mounting points on the chasis were the same from turbo to non-turbo. I've briefly searched on the topic before but I always ran into, "just buy a turbo model.
