karmagedon Posted April 23, 2009 Share Posted April 23, 2009 I've read the old mitsi engine conversion thread and there is nothing on the 4g37 in there. or even the 1800 4G37, that'd be different and bolt in like a bitch with the right manifolds etc off your 4G32 will this be true aswell for the 4g36? Would it just bolt in using the manifold that i have at the moment? What about the gearbox? will it bolt up to the 4 speed? Thanks for any help Dave Quote Link to comment Share on other sites More sharing options...
lowlancer Posted April 23, 2009 Share Posted April 23, 2009 Assuming you want to use the 4G37 (1800cc) with the 4G36 (1200cc) manifolds, is that right? AFAIK you should be sweet, ports should be more or less the same, possibly bigger on the 37 however. Gearbox also should be sweet. I'm sure Phil/fuel will point out something glaringly wrong though One question, why? Quote Link to comment Share on other sites More sharing options...

It would make sense for the 37 ports to be larger than the 36, however they might bolt up?? One question, why? well the 36 is just too slow all 1200cc of grunt just doesn't cut it. And at the moment I don't want to know a thing about ECI let alone anything else electronic, as my 7 is up to this stage and it's annoying the shit out of me. That leaves only 1 decently sized engine left : the 37. If that makes sense? Quote Link to comment Share on other sites More sharing options...
fuel Posted April 23, 2009 Share Posted April 23, 2009 Eliot you're forgetting 4G36 1200 is chain driven while 4G37 is belt driven - and they have different manifolds due to the position of the distributors between the two engines. You can drop in a 4G37 easy, may have to fit the 4G36 flywheel and clutch to fit in the existing gearbox bellhousing but they have the same crank bolt pattern so no sweat - then find a RWD 4G32 belt driven inlet manifold (EX Lancer, Sigma GL) and use that. You'ld be better off with a 4G63 in there though, the 4G37 really isn't a powerful motor and feels asthmatic especially up in the revs. It's mostly due to the camshaft profile they have. I guess with a better cam and some headers it will liven up the old 4G37. They're a tough motor too, not alot goes wrong with them. Quote Link to comment Share on other sites More sharing options...
lowlancer Posted April 23, 2009 Share Posted April 23, 2009 Are all 4G36's chain driven? I'm 99% sure my old old Lancer was belt driven? And karmagedon, I meant why the 37 as opposed to a 4G63? They're easier to drop in, no electronics to deal with bar dizzy wiring which is ridiculously easy and a couple of little things. Plus they can be already RWD Quote Link to comment Share on other sites More sharing options...

MACKAZ Posted April 23, 2009 Share Posted April 23, 2009 Nah certain some sigma 4g63s are carbied..... Quote Link to comment Share on other sites More sharing options...
lowlancer Posted April 23, 2009 Share Posted April 23, 2009 lol, no way jose Just good old carby fed broseph. There are EFI versions, but the one you want can be found in the old early 80s Sigmas primarily Quote Link to comment Share on other sites More sharing options...
karmagedon Posted April 23, 2009 Author Share Posted April 23, 2009 wow that above post from me had some messed up quoting. I guess in the long run that would be a much better upgrade then. With that then it seems I will need to following : Sigma Xmember Sigma 4G63 at the same time I suppose I can get the Gearbox and 'Box Xmember?? What about exhaust manifolds. Will the Sigma's work?

lowlancer Posted April 23, 2009 Share Posted April 23, 2009 Yeah you'll need the engine and box, and engine crossmember. Try get a throttle cable too, and make sure the box has the mount on it just in case yours is wrong (auto etc fuck knows). Probably worth getting your radiator recored or cleaned out too, and see if you can get the lot from a running car so you can check compression, cos it doesn't sound like you want to have to open it up. Sigma exhaust manifold will be sweet as for clearance, try getting some of the exhaust and flange after the manifold too to make it easier to fit the rest of the exhaust system Quote Link to comment Share on other sites More sharing options...
karmagedon Posted April 23, 2009 Author Share Posted April 23, 2009 awsome thanks for that advice. Do you know if all 80's sigma's are carburated? Quote Link to comment Share on other sites More sharing options...
lowlancer Posted April 23, 2009 Share Posted April 23, 2009 No, the next series changed to FWD and some versions were injected. Infact, some of the RWD series were injected, but not commonly. Quote Link to comment Share on other sites More sharing options...
karmagedon Posted April 23, 2009 Author Share Posted April 23, 2009 oh ok. So will have to make sure that it is RWD and carby. This is going to be a cool project for next holidays Quote Link to comment Share on other sites More sharing options...

OSM Garage Posted April 24, 2009 Share Posted April 24, 2009 Do the early Lancers run in to the problem of the shifter being to far back? Thought that might be a good idea to keep in mind when looking for a box I have a Sigma gbox xmember lying around if your keen. Just let me know.

lowlancer Posted April 24, 2009 Share Posted April 24, 2009 Yes. I don't know why everyone cares about that though. Get the angle grinder out, cut a 2" hole extension, done Quote Link to comment Share on other sites More sharing options...
P_Star Posted April 24, 2009 Share Posted April 24, 2009 yup, I just ended up with the angle grinder gear lever hole relocation after fucking about with L200 gearboxes and the like... a bit ugly but functional. The 63 conversion is a peice of piss... hell even I managed it lol... the project thread for that car probably went in the delete pile though I suspect Quote Link to comment Share on other sites More sharing options...
karmagedon Posted April 24, 2009 Author Share Posted April 24, 2009 yea I won't bother mucking around with different gearboxes. anglegrinder FTW Quote Link to comment Share on other sites More sharing options...
ProZac Posted April 25, 2009 Share Posted April 25, 2009 Just try to find an l200 box from a 2 litre 1980's l200 sport, should fit with one, with no mods. I've got one, wasent hard to find. Your car is pretty mint, would be a shame to go angle grindering it i rekon. Still, its your car, and if youve gotta do it to get some 2l awesomeness in there, go for it!
