I should already know this since I work with the 4G63 platform all the time but I'm a turbo guy and don't mess with NA versions much. A friend of mine wants to sell me his GS which has the NA 4G63 and it's got a dropped valve and hasn't been touched in nearly two years. New motor here we come. So my thought is to either drop in the spare motor we've one of the VR4s, drop in some yellow tops, and swap over the Super 16G I bought for the Cavalier turbo project. I already know the motor will drop right in because everything right up to the induction is the same. Coolant lines, fuel lines, accessories, and the current cat-back exhaust can all be reused. My brain fart, if you will, is whether the harness or any of the sensors need to be changed. I'll be using an EPROM version ECU from a Galant VR4.
The DSM in question is a 1990 (or 91 I'm not sure) Eclipse GS. Basically I'd be converting to GS-T spec.
Something tells me it wont work properly because the VR4 had that 4 wheel steering and a few other electronics that werent carried over into any of the 1G's
------------------------------------------------------------
since when did the galant VR4's come with all wheel steering??? myabe its just me but I've NEVER heard of that on a VR4
I thought about it and it'll work, the GVR4 ECU is same as a 1G (electronically speaking). The GVR4 did have different MAF though ( no lower HC ), so it might be wise to put a different chip in it.

Yep, I'm fairly sure the 4WS was VR4 "Option only" but they did infact come with it, as welll as the 3K GT's

Yea the VR4's came with 4WS. Just go look on the boards, most of the guys disable it. I seriously considered one of these cars but then wised up and bought somethign reliable.
Since when haven't VW's been reliable?
He never said fast.

learn somethign new every day
I've never heard or sen it mentioned on the galant

I hope your joking..... reliable VW is liek an oxymoron

You can use the engine from the VR4 Galant but you cant use the transmission. On an Eclipse/Talon the transmission sits on the passanger side. On the Galant it sits on the drivers side.

Kinda the same for DSM

No. First Gen Galant VR4s and all AWD DSMs used the same transmission/transfer case. The difference was in the first gear ratio. DSMs had a bit shorter first gear. All First Gen 4G63-powered cars had the same orientation with the transmission on the passenger side (or driver side in the case of one of our VR4s - it's a JDM). The only change was with the latest versions of the EVO, in which Mitsubishi redesigned the 4G63 and reversed the orientation.
And yes, the GVR4 came with AWS. But it's only active at something like 35mph or higher and the degree of steering isn't all that much.
And using the GVR4 EPROM isn't a problem. We swap ECUs between the GSX and GVR4 all the time because for some reason the capacitors like to leak onto the boards and fry them. It's jsut easier to replace the ECU than try to fix it, and GSX ECUs are just easier to come by.
But anyway, I got my question answered last night on the GVR4 board so thanks anyway.
And today on Muppet Science, we will turn Gold into Cottage Cheese.
And now for something completely different... Click the Minister.

True, also came on the stealth R/T turbos.

Yeah also right alot of people remove it cause i think it is like 30-50 lbs worth of stuff, i think its cooler to say i have aws lol. As for the cars not being reliabe, the vr4 is a very good motor, if you take care of it it won't have problems, my motor is just over 110k and i have no problems whatsoever.

4G63. VR4 is a trim level/performance package. And you are correct, that if maintained properly, they are reliable motors. But they are maintanance hungry little bastads and not every kid that gets a DSM for his 16th birthday understands that, which is why so many people take a negative view towards them as being "unreliable".
Which reminds me. Time to change your timing belt if you haven't already cuz you don't want it breaking on you. Trust me. Mine broke at 5K RPM, and destroyed almost every single valve. Not to mention the cylinder walls and the pistons were pretty much destroyed and a bunch of teh rockers had been dislodged from having the valves shoved back up into the head.

Yeah those damn capcitors and leaking out on the circuit board suck. It took my a while to figure that one out on my old DSM. It was only firing on 2 cylinders and normally when the capacitors leak fry the board it shuts the whole car down.
