individual throttle bodies

[SWAPJUNKIE]

it was a 316 that had a rubber mounted single barrel carb.

Didn't the e21 have a carb'd m20? Can something from that be used? I know the displacement was 2L I have suspicions that the carbs might be too small. But something should work.

Yeah the E21 320/6 had a downdraught carburettor, no where near as good as multiple sidedraughts, or even multiple downdraughts

[Hadrian]

Show me where to get an m20 triple side draft manifold.

Easiest way would be to cut the standard manifold ~6 inches and weld some straight runners onto it. Then weld some DCOE/DHLA adapter plates onto each runner. Then you could drill some holes for vacuum if needed.

I have no interest in running carbs on my m20. I eventually would like to run ITB's but I have no intestions of doing that much work for it. I have seen the m20 triple dcoe manifolds on ebay before. When I find one priced right I will get it and run ITB's from these guys: http://extrudabody.com/index.html First I will do this on my e21 with an M10 I am building. Dual side draft manifolds for the m10 are easy to find these days.

TWM makes THESE .

They used to offer carb manifold too but it looks like they sold the carb stuff to THESE GUYS .

[mcgrath]

nothing for the M20 though :( I contacted pierce a few years ago and the only six cylinder manifold they had was for the m30.

Not you if you are turning an Eta into a drifter

I'm looking into it but the cost far outweighs the benefit. You can extrude hone an intake and use a BBTB and get just about the same results.

First you have an eta motor - ditch that and buy yourself an IS motor - or drop ~$5,000 for a decent motor build (you can easily spend double that). You'll realize quickly that what you want is more easily acheivable with a turbo, m30, 24v or other swap. You don't want to drift in an eta - you don't want to do anything in an eta other than get really good gas milage and drive easy.

Get:
High Comp pistons
bigger valves,
cam
ported head
BBTB & extrude honed intake
extra oil cooling
exhaust
pusher fan (delete the stock fan)
Heated wire MAF conversion
chip or standalone
crank from your eta or other 2.9, 3.0, 3.2L stroker

Build it then learn to drive it then learn to drift so you don't put $20k into a wall....

oh i can drift the piss out of it right now im just getting ideas in my head im trying to sell my jeep and im proly gonna drop all my money on the 30 and i got 2 m20 motors i just cant decide if i want to fix one up or say screw it and go with an m or s50 and im kinda leaning more toward a procharger setup i know someone with a kit that i should be able to fab up and make work. Has anyone done a procharger yet? any other ideas id love to hear.


Oh yeh ne one wanna buy a cj-5 with a hardtop which almost impossible to find.

[92 mtechnic cabrio]

this thread is full of wishful thinking

[homegrone30]

hopes and dreams are all i got with no $$$

Show me where to get an m20 triple side draft manifold.

went to google and found this in a for sale section of a forum after searching for "M20 DCOE manifold".



As for getting some carbs I'd suggest going to a junkyard and looking for some 240Zs or going to forums FOR cars of that type. You're bound to find someone on the boards who took on a project car they can't afford and need to make some money quick. Or if all else fails.... Ebay. They have plenty of Weber, dellorto, SU, and even some Mikuni carbs for a decent price.

[swimstarguy]

I've been thinking about putting carbs on my m20 as well. The hardest part about building a stroker is tuning the electric gizmo. No worries with a carb. I can handle that well enough. Junk yarding some Webbers sounds great to me, but don't they have a problem with lateral loads? I've heard that side draft carbs run lean or rich, depending on the direction of the turn, when you sustain lateral g's for a bit. Not so with downdrafts.

Has anyone found or heard anything about that or m20b25's with carbs other than rumors?

[Ryosuke]

Dellortos and mikunis are the only carbs I've really heard of having that problem from load shifting. Webers were designed to replace those models so I think they should be superior in performance. I didn't mention this earlier but I think it would be really cool (read: not practical but different) if someone ran a slide throttle type carb setup akin to the FCR carbs that are used on some toyota 4AGs.

Anyway, I may do a carb setup on my M20 depending on what happens later on. If so I'll be sure to do a writeup :)

a moderator should change the thread title to "outdated technology"

Dellorto DHLA are modelled on Weber DCOE. DHLA came after DCOE, so going by your logic DHLA should be better than DCOE.
