dohc swap? in 94 ls

[Jamfish86]

sweet and simple i have searched this but iPhone sucks on this forum and wont let me do much. i have 94ls i have got 1g 2.0l with 43,000 original miles and a 5 speed ? miles. i have done all the simple swap stuff changed front mount and all that got it in the car and all bolted up. well i have been changing all the wiring around for the 1g ecm and power transistor and coils. well today i found a 94 gs sitting in salvage and i know the engine is similar to the 4g63 but i was wondering if i could just use that harness and ecm and run with it while finishing the other harness. i'm in a pinch cuz my 97 is about junkyard bound and happens to be my daily driver, so it pushing me to finish my project asap.

[Jamfish86]

So for turbo 7g guys, I picked up a 07 Pontiac solstice intercooler a few days ago and fits Like a glove minimal cutting and hacking just need to weld some brackets and trim lower bumper cover a little no cuttin impact renforcenment bar. If I can figure out how to put pics from iPhone Ill do so.

A GS has a 2.4 4G64 DOHC stock. its a 7 bolt with a 2g head style. that GS motor has 160hp stock non turbo. rebuilding that even to stock specs then turboing would yield good results. you could use the GS harness ans everything just have to rewire for a 1G style cam sensor as it has the 2g under cam gear style and then the crank sensor under the timing belt. also the GS uses a 2g knock sensor and coil packs.

as for pics, send them to your photobucket account then you can post them easily.

[Jamfish86]

Right on thank you for the reply and info. Hopefully I can pick up that harness and ECM soon

[Jamfish86]

do i have to do a rewire for the 1g cas or can i just get a 1g to 2g adapter harness since the gs uses a 2g style head or just make one that way i can make it look factory

[Galanttuner10]

you can rewire the same way a 95-96 car would have to or buy a harness from magnus, just be sure to email them at length to get the right harness

[Jamfish86]

Well I waited too long the junkyard that had the gs sold the whole car I guess I gotta figure out how to finish the rewire for the 1g ecu

[Jamfish86]

Ok can't get the car to crank over. I'm stumped, I can hit the key and it makes a grind noise. Idk what it could be im runnin a 6 bolt 4g63 that was originally out of a 91 eclipse with auto tranny,flywheel is from a 94 eclipse 6 bolt of coarse,clutch was ordered for 96 galant and the tranny is from a 96 galant 5 speed and the starter came from a different 91 or 92 gsx eclipse turbo 5 speed. All bolted up well even starter and everything is good parts so not question of starter being bad. Any input cuz I got me a gs harness and ECM on the way and well I wan2 hear this thing run

[Galanttuner10]

You need a 94-98 galant 5 speed starter plate and a galant starter preferably new. Is it a FWD 6 bolt flywheel as the AWD flywheels are smaller and could result in the grinding as the starter would be barely reaching the flywheel and grinding the teeth away.

[Jamfish86]

well i fabbed up my own starer plate using 24 gauge steel sheet metal and used the bell housing as a templet then bolted the starter and plate to tranny while out of the car all fitted well. do you know the tooth count on the awd and fwd flywheels so i can compare. and parts store says same pt# on starters are same between eclipse and galant as long as its standard

[Galanttuner10]

starter numbers should be the same. and do you have a stock flywheel from the galant as its the same size as a fwd turbo one. pictures would help a little as well.

[Jamfish86]

dont have the galant one as i bought car with no motor a tranny and i bought the 5 speed from jy that all ready had it pulled from car http://i1243.photobucket.com/albums/gg556/Jamfish86/72ae20e4.jpg

[QnzMostWanted]

ok, ur problem is the flywheel/clutch setup, the 63 NA on the 1g uses a different clutch pp setup than the Galant, u would need to get a 6bolt turbo flywheel, not an N/A one

flywheel for the Galant tranmissions should look like this:

http://i143.photobucket.com/albums/r132/Qnzfinest1981/166b_1.jpg

the NA flywheel is too small for the galant transmission (look at how the teeth are on urs vs the ones i posted), the grinding noise is the started not engaging on the flywheel, get the right flywheel and u will be all good to go

[Jamfish86]

i was under assumption that all 1g fwd were same and awd were diffrent, but i see diff now thank ya guys for help

[QnzMostWanted]

theres 1g FWD NA, 1g FWD Turbo, 1g AWD, 3 different flywheels

i was in ur situation not to long ago looking for a clutch for my car due to all the different setups, but i figured it out eventually lol

[mko]

All clutches should be the same, and IDK about the differences in 1g n/a and FWD flywheel. They should be the same as well.

[QnzMostWanted]

for the 1g there was a 215mm and a 225mm clutch, the galant uses a 225mm clutch, the 215mm clutch is a different spline count and wont work on the galant transmission

the flywheels are different in being stepped (turbo for 225mm clutch) vs non stepped (N/A 215mm clutch)

even tho my GS was non turbo, it came with a F5M31 which uses the 225mm clutch (same as the 7g) and the flywheel says 63DT (turbo flywheel)

[Galanttuner10]

maybe all 2.0 flywheels are the same and the smaller clutch is probably the 1.8.

[QnzMostWanted]

1.8's used an even smaller clutch
200mm for the 1.8
215mm for the 2.0 N/A
225mm for the 2.0 Turbo
225mm for the 2.0 AWD

tho the AWD had a smaller flywheel by 1/4 of an inch

if ur using a Galant 5spd from a 7g the transmission code should be F5M31, the flywheel setup for that as a 6bolt is the same as the 1g Turbo which also uses the F5M31 transmission....the other flywheels like the one he has on his setup is for a 1g NT DOHC which uses the F5M22 tranmission which has a smaller bellhousing and a 215mm clutch

[Jamfish86]

Yeah mine is a f5m31 from 7g

Thought I'de post a pic of when I saved it from junk yard and how it sits now.

[QnzMostWanted]

yeah so once u get the right flywheel u will be good to go

right now ur clutch wouldnt even disengage on that setup because there is no room for the clutch to go

[QnzMostWanted]

pics need to be fixed, but i was able to see them, im surprised u revived it from a JY, good work

[Jamfish86]

Think I got e'm fixed, it was originally a parts car for my 96 as I smashed a deer scootin down the rd at 70 mph then after I got it home I quickly realized it was in far better shape than my rusty smashed up 96. So began searching about the swap and well here I am now, needin a little help from you guys who know more than me about dsm's. I really thank you guys and tgc because know one around here in mid mo. knows much about this stuff either.

[Jamfish86]

Dose anyone know where to get a gs ecu I bought one and it's not same as one he had pic of its got to be a obd2 one cuz it has 4 plugs. Guy hasn't responded back to me yet maby he jipped me or maby just sent wrong one idk but tired of dealin with him(NOT a MEMBER here) local mo. Junkyard guy

[Galanttuner10]

Sometimes they end up on eBay. If you find anything that seems right post up the part number and I will make sure it's a GS ecu

[Jamfish86]

Yeah I look but never see e'm, isn't the number md304189 for dohc?

[Jamfish86]

i went up to kcmo and kcks this last week to a you pick it junkyard and got a bunch of goodies real cheap like stainless exhaust of 2g,turbo mani,resistor pack,turbo 1g throttle body,side mount ic for 100 bucks then today i got my 5lug conversion with disc rear,turbo mass,broken p.o.s 2g bov, piping, resistor pack, and bunch of other odds and ends for 50 buck cuz there smashing the car

[Jamfish86]

Got my flywheel, got it in but I haven't figured out the mpi relay yet. Although I did use the fuel check connector to jump fuel pump and got it to start! Thank goodness. Not far from bein road worthy now

[w/oarctic7g]

So did you end up with 1g or gs ecu?

[Jamfish86]

The 1g EPROM

[Jamfish86]

This how she sits now

[Jamfish86]

its running now,had 1g Ecu pin 110 hooked up wrong. Its holding real good idle but when i give it a little gas she hesitates and seams a little choppy. But i still don't have pins 63 and 66 hooked up,both supposed to go to mpi relay. Any thoughts?

[w/oarctic7g]

It looks like they both should go to the small black/blue at mpi.

[Jamfish86]

I'm not sure, i know that when the ecu pin (110 ig1) gets power it pulls 63 and 66to ground which is pin 8 of the 1g mpi relay.

[w/oarctic7g]

The GS ecu pin 38 has the same function at mpi #6( battery+ key off then 0-3v key on) and the 94-95 sohc doesn't seem to use it. Can't imagine the function being different of the mpi. idk

[Jamfish86]

Yeah i just put them on the mpi ground nothing changed. Also i managed to do something wrong with the maf. Im using the 501 out of a 8g but car all stupid when i have it pluged in,without it runs and revs up fine just got high idle. What's a better maf? I used this one because its round and connects to intake pipe easier.

[w/oarctic7g]

I have had good luck with my 7g maf's with a $10 round filter adapter not sure of the benefit of the 8g or wiring differences. Try leaving the iac at the throttle body disconnected, on cold starts you may need to hold the throttle for a few seconds is all.

[Jamfish86]

I just used it because that's what I had at the time now I have that and a 2g turbo one. But I figured that the 2g would make it run funny untill I buy a new turbo and injectors.

[Jamfish86]

So its been awhile since i have posted. The galant was running like a top for about 2 weeks then my water pump failed me and got hot and blew head gasket. So now its tear down time again but the good news is i got a steal on a 1g laser $500 and was loaded with goodies such as big 16g turbo,all aluminum radiator,turbonetics boost controler,nice 17's with new tires,eprom ecm,and all kinds of gauges. So now i have everything i need for a decent 4g63t galant. The 1g was boosting 20psi and would sit your ass in the seat. But i like the room in my g more than a 1g! Lol

[Galanttuner10]

Sorry to hear that. Good luck. I would still rather a 2.4 but if you go to 2.0 enjoy it
