4g63t / AWD 7g Build

[seth98esT]

I had my 98 FWD w/4g63t swap weighed at a truck stop once and it pushed the scales at about 31xxlbs if I remember correctly.

[hk20000]

Just for reference a 7G VR4 weighs at 3315lb... With the complications of 4WS is the most likely reason for the weight increase from ur conversion. the 6A motor is only heavier than the 4G by a feather.

Got the TPS issue more or less resolved this morning. Turned out the stop under the gas pedal was the problem. I cut the section off that rises up above the carpet and now I see 12%-98% throttle. I'm still missing 4% but even without the cable moving the throttle I get those readings so it is probably the sensor at that point.

just an FYI the 2g non cruise cable will work

If I can I plan to use the cruise since this is going to be my family's road trip car.

On a completely different note, the Colorado DMV once again proved themselves better organized than the NM DMV. I gave them a call this morning to see if I could get temp tags for the Galant. After listening to my situation they sold me a set of 60 day tags for $6.20. So the Galant made it's first debut on public streets this afternoon. It definitely needs some tuning as the car was running pretty lean. In the mean time I'm poking around and working on getting the speedometer functional. I have confirmed that I have a good connection between the sending unit and the gauge cluster as well as a good connection within the cluster. Oddly enough I'm seeing a steady 4.5v going to the speedo. I am off to do some more diagnostics now. DOHCStunr did give me some advice as to what may be wrong but I'm going to dig around a bit before hacking at my wiring. Wish me luck!

remember, the speedo is all about frequency, not voltage.

if you moved the speedo half a tic forward there wouldn't be any voltage i imagine.

In fact you were right. I went through all the diagnostics for a 2g DSM speedo system and checked everything. I also switched back to the M/T speedo sensor from the Talon. After doing some diagnostics and confirming that everything was working ok I gave up for the day and drove to work. That is when the speedo randomly started working. It was very jerky and slow to respond though. So this morning I pulled the speedo plug off the tranny and looked at the connection. The tongues inside each of the connectors were pretty depressed so I pulled them out of the harness and bent the tongues back out to make better contact. I'll see if that resolves the problem.

I was in contact with Alan To regarding my bad JAW 1.041 unit. I shipped it back to him on Monday and will get a new kit sent to me when he gets mine.

I also have a set of Koni Sport shocks and Ground Control coilovers on their way. I found a complete set used on DSM Tuners. They have the hats and everything. It is exactly what I was after, a $1k+ suspension slightly used for $450 shipped. Right now the rear tires are rubbing the fenders on big bumps due to the FWD shocks in the rear lowering it slightly. It'll be good to get it raised back up to factory height and get my alignment done too.

I'm still waiting to be able to tune but I've been driving the car around for a while. I am absolutely loving it. All the work was definitely worth while. I can't wait to get it tuned, get the new suspension under it and really let loose.

That is a killer deal on that suspension setup. Koni and Eibach make a great pair on our cars. A buddy of mine had a 94 GS with Koni and Eibach Sport springs. It rode like a dream!

[SPD_FRK]

You have done a great job on this man. Glad to see the DMV gave you a break, I have had my share of fun wth them and have yet to deal with them on my Galant.

It would be really cool if you, Ivory8G and myself could all meet up somewhere in the middle for some fun...I'll be dead last of course lol.

Took the car down to an Albuquerque DSM club meet this weekend and drove up Sandia Crest road with the guys. The Koni's were great and the car handled wonderfully. I did have some overheating issues though. I don't have a problem normally so I suspect it was just the heat and long climb. With the car tuned in right and a little duct work I think that'll disappear.

A few other kinks: my A/C doesn't work right yet. I need to rewire the system as the dash button doesn't trip the A/C clutch right now. When I ran a jumper cable to the clutch the lines didn't cool down so I think it needs to be charged too. Just one more wiring project to tackle. Should've just gone with the 2g harness and an Evo ECU but I'll make it work.

[phizzalot]

That sounds great eclipsh...If I find a good deal on some rear parts I may not be able to stop myself from buying them, now that I see yours up and running :)

my buddy has a 95 shell hell give me for 400 with the whole rear end but im broke, but no1 wants it so i think next spring this will be my next endeavor

Of course this will only work with OBD 1 7G and 1g turbo ECU's.

Well I got the tach in the Galant working today. I decided I want to use the LED displays from the JAW as a HUD unit (mirror off the windshield). I gave using the tach out of the Turbo DSM another shot and it works. I must have had some wires backwards last time. So I combined the face plate from the Galant cluster with the electronics of the Talon tach. The bolt holes on the rear of the gauge cluster are not the same for the electronics so I had to custom mount the electronics and then run jumper wires to the correct holes. I used the face plate (#'s) off the Galant too. I double checked the RPMs on the Tach VS my logger and it is dead on. The redline is different but it works :)

[Spartan251]

post up some pics of that cluster. HUD unit in a g would be interesting.

[eclipsh]

Wow, been a while. I haven't put any work into the HUD system, I've been too busy with school and work this fall. Last Friday I had a surprise while my wife and I were heading home from my parent's house. Something seized with a horrible metallic screech while I was going 65mph. I dove for the side of the road and killed the engine. After digging through my glove box for a flashlight I ducked my head under the car to see if I still had a drive shaft and to look for puddles. Everything looked normal. Thinking that it might be the engine I grabbed a wrench from the trunk and pulled my timing belt cover. The belt looked fine. A quick crank of the ignition and the engine fired right up, happy as could be. I gingerly put the car in reverse and backed further off the highway, turned the heater back on and called my parents to come pick us up.

The next morning I drove the pickup my parents had lent us the night before down to Uhaul to get a car transport. A few hours later the Galant was up on stands in my garage. I started out with draining the rear diff since memory indicated the noise had come from that direction. No shrapnel and plenty of fluid. From there I moved up to the transfer case. The drain plug was wet. I pulled it out and watched as a slow trickle of oil fell into my drain pan. A few seconds later something heavy thunked it's way into the pan. Turns out the plug never got tightened up all the way or worked its way out and let all the oil go. My transfer case was toast.

Thankfully I got a spare when I swapped my 1g DSM for the 2g donor so I set about pulling the transfer case out and installing the new one. While I had the g up on stands with the exhaust and drive shaft out I spent some time bending the heat shields further out of the way and grinding the center flange on the exhaust down. The result is that I now have a bit more clearance in the tunnel.



Turns out it was probably a good thing the t-case went. As I was poking around I also found that both front wheel bearings and a couple ball joints were in bad shape. In my rush to get the car build I didn't realize the condition they were in. I'd seen a torn boot but forgot to check for play. It was bad enough I decided not to drive the car until everything was replaced.

I decided I'd give Mitsubishi a call to see if I could have the ball joint recall performed on my g. As it turns out the Galant had the ball joint recall service back in '01 so I was out of luck. However, when I built the car this spring I switched the knuckles and control arms from the Talon to the Galant and vice versa so I could keep my 5 lug hubs and wheels. I decided to go check my donor Talon and see how the ball joints on it were. They were in great shape, just one little nick in a dust boot that doesn't go all the way through. So I pulled the knuckles/arms off the Talon and with a few blows from a 3lb hammer knocked the hubs out. I should have my new hubs any day now and will put the front end of my car back together as soon as they show up.

I should also mention that the drive shaft held up great as did the custom mount. I couldn't see any signs of damage to either one.

[skrap]

Im glad to hear that it wasnt any major damage!!!! I would love to eventually pull this off. Your build thread made this seem very easy. IYO how difficult was this build? Also you should make some videos of you driving inside the car and also a vid of you driving down the street with the camera outside the car!!!

[beam514]

how the hell did I miss this build?

good work! sucks about the diff. but at least you had a spare

[DOHCstunr]

Sprinkle a little DSM pixie dust on a 7g and boom you lose a transfer case. Oh well, at least it was a simple fix.

Yeah i was under my car a while back and just took out the heat shields all together. I didn't really see a point in keeping them.

Needs more pics! lol.

[Shadow19]

Man im so intersted in this its not even funny.. I wish the JY had a donor 2g AWD!
