lowlancer Posted November 11, 2008 Share Posted November 11, 2008 Basically they're shit and you'd be better off with a 32/36 weber jetted to suit. Quote Link to comment Share on other sites More sharing options...

fuel Posted November 11, 2008 Share Posted November 11, 2008 they wouldn't be off a GTO if they're from a 4G32. Most likely Mk1 Colt GT which is FWD - do all the water lines route up right, and is the manifold on an angle to suit RWD? Quote Link to comment Share on other sites More sharing options...
rwdlancer Posted November 11, 2008 Author Share Posted November 11, 2008 Basically they're shit and you'd be better off with a 32/36 weber jetted to suit. not enough money for these.looked around for ages and a manifold would be hard to find. these twincarbs were 70bux all up so mean deal i thawt Quote Link to comment Share on other sites More sharing options...

lowlancer Posted November 11, 2008 Share Posted November 11, 2008 Get an adaptor for your manifold, relatively cheap, and a decent 32/36. Bang. Sounds like you've made up your mind anyway I've talked to many an internet dude about those. Basically there's nothing WRONG with them but you won't get much power from them, or sound if that's what you're after. You'd be wise to rebuild em also and that'll be tricky partswise. Meh, up to you. Quote Link to comment Share on other sites More sharing options...
rwdlancer Posted November 12, 2008 Author Share Posted November 12, 2008 What is a 32/36? a single carb? i had a 2 litre ex lancer carb on it before hand. the engine sounded it wasnt getting enough fuel.theve already been rebuilt and cleaned up pretty well.i started up before and its definatly alot louder and sounded way better.maybe i should just rebuild the 2 litre carb Quote Link to comment Share on other sites More sharing options...
lowlancer Posted November 12, 2008 Share Posted November 12, 2008 Yeah it's a twin barrel downdraught, manual secondary throttle, unlike both your options which open the secondary throttle (s ) on vacuum. I'm pretty sure that's all correct but feel free to correct me anyone Adaptors are on trademe for cheap, you'll just need to fuck around with the throttle cable and probably the tuning, but nothing major Quote Link to comment Share on other sites More sharing options...
fuel Posted November 12, 2008 Share Posted November 12, 2008 those twin carbs are off a RWD car due to the location of the thermostat housing - but they're off a chain drive motor (so probably something like a Colt 16L etc), and I'm pretty sure they wont fit on a belt driven motor such as the EX Lancer 4G32, think it's the distributor position which mucks it up as the chain drive has the dizzy in the block while the belt drive has the dizzy in the head right next to the manifold.

rwdlancer Posted November 13, 2008 Author Share Posted November 13, 2008 well they fitted on sweet.got the car started by pouring petrol dwn the throat and sounded much louder.but i dnt thnk they were getting any fuel. so just chucked the sweet 2 litre carb back on and gna leave it at that Quote Link to comment Share on other sites More sharing options...
Burabuda Posted November 14, 2008 Share Posted November 14, 2008 yep they are junk. mine are junk. secondaries not operating; sputtering start ups, etc. i did some research, and realised they aren't worth bothering over exception; good if you got a low mileage minter as a show or museum car i still have 'em on my gto, and the whole motor's coming out, so i'm not bothering changing them Quote Link to comment Share on other sites More sharing options...
fuel Posted November 14, 2008 Share Posted November 14, 2008 they're real similar to the carbs found on twin carb downdraft toyotas - ie 2T-B, 3K-B etc - both Aisan carbs. Quote Link to comment Share on other sites More sharing options...
Guest ganja_gorrilla Posted November 16, 2008 Share Posted November 16, 2008 so would a single weber 32/36 be far better ( power and economical) than my factory twin downdrafts? wat about putting 2 webers on there sinse i have a twim manifold alreay?

rwdlancer Posted November 17, 2008 Author Share Posted November 17, 2008 i was thinking of doing the same thing with my twin carb manifold but using 2 2litre ex lancer carbs instead.think it would work? Quote Link to comment Share on other sites More sharing options...
Ogre Posted November 17, 2008 Share Posted November 17, 2008 i have had both the 32/36 and the same twin downdrafts on a 4g63, both on same engine.Twin carbs and the downdraft where the same power wise.twins revved alittle better, songlehad more low down power, bust still revved fine.twins sound alittle better.I spent like $600 on the twin carbs, rebuild etc and they where still pretty crap. i seriosly would bother with them, although some twin downdraft webers on the twin mani would be mean.ida's even (fuck knows what they are called) Quote Link to comment Share on other sites More sharing options...
lowlancer Posted November 17, 2008 Share Posted November 17, 2008 Look, just put on a a single 32/36. They sound fucking awesome and work well. Quote Link to comment Share on other sites More sharing options...
