Hey guys

I have a 1996 CE Lancer chilling in my driveway. I've converted the 4g15 over to a 4g93t. It's the lastest gen with the engine on the right side.

This is my gearbox F5M421-F8A7-AQ2944. FWD. Now I'm not 100% sure whether it's a N/A 4g93 or 4g92 Mivec box...

It all bolts up fine but none of my starters will engage the flywheel... too short and too narrow. The flywheel on there is stepped, which is half the problem. So I decided to try a few bigger flywheels that were flat. They looked more promising in regards to mating with the starter but they won't fit my bellhousing.. :/ Back to square uno

The flywheel on the crank now is 268mm diameter, this is sliiiightly to small to fit touch the starter. So I can't even machine down the step because it's too small.
I have another flywheel which is unknown, roughly <280mm

Does anyone know which starter I should be looking for? I could go out and buy an AWD 4g93t gearbox and lock it to FWD easy enough but I would rather not as their gearboxes are kinda steep right now.

Other than that, the only other problem I have is trying to fit the clutch slave cylinder correctly as it fouls majorly on the turbo's intake pipe. I daresay it would prematurely wear my clutch down if I just chucked it on as is.

I am reeeally desperate for some help guys. BTW I HAVE scoured the forums and maaaany more over the net. I'm not that guy :p
I'm just not finding this one piece of crucial info somehow... hmm

Thank you so much to anyone who can help me out here
 
I know sfa about those later motors. But if your starter plate matches your gearbox (sounds like it does) then you need a bigger flywheel (like you say) surely there is some way to get a listing of ring gears available and compare these to what you have.
Your unknown flywheel will be 6mm closer to the starter. Is that enough?
I reckon it will be about right.
I dont know how you could dummy it up to check clearance before pulling it all out. Maybe a square measuring out to the centre of bolt holes from the ring gear. Im using a phone camera to take pics where I cant get my head. Post a pic of the starter hole. You should be able to see if the ring gear is in correct place.

I dont think there is any different starters. But I got the starter plate, torque converter and srarter all from same car. Just in case.
 
Hey cheers for the replies guys. Yeah I thought that unknown starter would do the trick but it's actually too big for the bellhousing.. Sucks
I might try that parts world and have a browse through the flywheels.
Aw the engines already out too since I'm doing alot of work on it. Forging out an Evo4.5 to drop in it too. Still needa figure out exactly which gearbox to do the trick though. Will go AWD one day but for now FWD will have to do the trick
 
Yeah done that. I think I need something around 278mm. I'm a lil nervous about tryna fit that inside my bellhousing though
 
So dummy it up. Assemble clutch and flywheel, assemble onto input shaff. Push in till it just clears bell housing and straightedge across housing and measuse down to flywheel flange. This distance needs to be more then the crank boss sticks out back of block.
May as well check starter while its there. Bolt it up and have a look.
 
I'm thinking it's gonna be easier just to take the gearbox and engine into a parts dealer and sit out the back with their flywheels. Mock something up then buy a matching aftermarket clutch. Honestly it's not as simple of a problem as you'd think. I had 3 engineers from Mitsubishi all scratching their heads lmao was pretty disheartening to see really.
I'll let you guys know how I get on though ^ ^
I should do a build thread coz it's a pretty impressive one really. Just really back and forth atm though
 
Quick question. While I'm building the Evo engine up, I wanna play with some decent boost on my GSR. I'm getting forged H beams but I wanna know how much boost the stock pistons can handle roughly if you know? With a good tune of course
Legeeend
 
if you are going to mess with the stock piston and higher than 15psi, you will need to have very conservative timing as these pistons have pretty weak ring lands and det messes them up really quick.
 
Hmm I may just go to forged pistons aswell to save my skin then. Wanting 18psi+ on the gsr. Aiming for 25-30 on the Evo
Cheers guys
 
if you are going to go for forged rods and pistons...also get the evo main studs for the bottom end.

you will need to give the sump a whack at the very back to clear the studs but other than that ...straight swap and pretty much a bullet proof bottem end as long as you dont get a complete muppet to tune it.
 
Evo studs on the gsr.. Really? Hmm 1st I've heard on that one. I'll have a look into it though. Cheers.
I'm doing the tune myself. Emanage Ultimates already wired in, updated and good to go. Only time it will see dyno is for cam timing after I install nitrous and on-boost meth injection.
 
Buzzy. I'll have a hack at it. Yeah I've sourced some 3sgte head studs already.
Was just reading through your daughters forged 4g93 Brian. Did you ever end up resolving the tick? Was it anything to do with the Wiseco's?
Looking at some Wiseco's for myself. Only really want pistons so I can spray a 100hp shot. Being able to up to boost over 18lb is just an added bonus really
