Author Topic: EFI on a 20r head? (Read 3468 times)

Tice · « **on:** Dec 28, 2006, 03:38:11 PM »

Has anyone here done it or heard of someone/place that makes an "adapter" for that? I met a guy a while back that was working on an intake for the conversion but he has since moved to AL. I'd like to make one but don't think I have the patience!!

i think Marlin or WillyMammoth would be the only ones that could do it

Well than one of them needs to make one for me now!!!

I wanna run the 20r head on my buggy but don't wanna lose the EFI. I'd go propane but the wife wont let me spend any more money!!!

An EFI hybrid motor is definitely a dream of mine, or better yet EFI hybrid turbo'd... Anyway, if you're not allowed to spend the money it would cost for a propane conversion, then I would assume you won't be allowed to spend the money it would cost for a custom intake since that would probably end up being some serious dough. You could always try mechanical fuel injection. Some guy over on pirate has put together a kit using VW parts. Good luck, whatever you decide.

just get your 22re head ported and polished with some oversized valves and dual valve springs
ive heard somewhere that chevy valves fit in a yota head, but im not for sure?

Dig up my thread about this subject, in project research I think, and look toward the bottom. There's a good link there for it.

Also, I just today found this for using vw/audi injection, and while it looks a little cobby it seems to be fairly well built. http://www.zuksoffroad.com/products/MY-T-FI.htm

It wouldn't be done right now, in a few months when my head "goes to hell on me" and I have to fix it.

She'll let me spend money for that. She knows about the propane kit but says there is nothing wrong with my stuff now so why "fix it".

I was more or less looking for something that someone has done them selves. Thanks for the link.

Thanks. I couldn't find to much in the search. But I give up easily!!

That link that nate posted is essentially the same link I gave, it's just the one a gave him was a link to the thread that the zuks offroad link was in (if that makes any sense). Anyway, just thought I'd point that out.

yotakid88 · « **Reply #9 on:** Dec 30, 2006, 03:42:09 PM »

you could have a intake setup the used tbi insted of injectors. you would just have to have a spacer/adptor made or you may be able to find one.

kneedownnate · « **Reply #10 on:** Dec 31, 2006, 12:04:36 AM »

Yea, but where's the fun in tbi? I'd rather a muti-point type setup, but I like a dash of trick with my function.

It can/has been done. A guy in Tacoma has done at least this one:
http://smg.photobucket.com/albums/v368/OldMage/20RE_head/

He elected to weld up the 20R head and port it to match the 22R manifold, but I believe the 20R and 22R bolt patterns are the same. I was thinking it might make more sense to make a 1/2" thick aluminum adapter plate to use between the manifold and the head. I wouldn't want to go from the square ports to round inside that half inch, but you could probably go about halfway, and then port the head halfway to square, to make a nice smooth transition. If you bolted the plate to the head and then ported them together to match the 22R-E gasket opening it would be nice and smooth and probably wouldn't bit into the head enough to cause any trouble. Then get longer manifold studs, trim the 20R intake gasket to match the ports, and away you go.

I know "the guy". He has some funny ideas (no worse than mine), but is not a crackpot.

Tice · « **Reply #12 on:** Jan 04, 2007, 02:13:12 PM »

Thanks man,

That was exaclty what I was thinking of. Using an adapter plate or wleding up a whole new intake runner to fit the 20r head. I just can't weld aluminum!

Does anyone know if the bolts are in the same place?

te51levin · « **Reply #13 on:** Jan 04, 2007, 03:47:47 PM »

I'll order a 20R gasket and compare it to the 22R-E one just to see what they look like.

Tice · « **Reply #14 on:** Jan 04, 2007, 04:18:06 PM »

Not a bad idea.

I'll run down to the local parts store and just compare the two.

dcg9381 · « **Reply #15 on:** Jan 09, 2007, 01:28:39 PM »

Because the 20r head ports are round, I'd think it would be relatively easy to fabricate up an intake manifold for it... Might talk to Tim @ DOA, I thought he did a port conversion, similar to what oldmage has done also.. probably cost prohibitive.

te51levin · « **Reply #16 on:** Jan 10, 2007, 08:22:08 PM »

It wouldn't be too hard for someone with the ability to weld (preferably aluminum), but I think I'd much rather modify the existing manifold - weld the ports down to a round shape - or just make an adapter plate. I compared the two gaskets today to see what is the same and what is different. I don't have a 22RE manifold to look at right now, but as long as coolant flow and volume through the tall rectangular outlet betwee ports 1 and 2 is not absolutely critical, I don't see any reason this wouldn't work.

The red area is the port shape difference between 20R and 22R. Not too radical, really, and practically zero at the roof and floor.

kneedownnate · « **Reply #17 on:** Jan 10, 2007, 11:21:48 PM »

So should I pick up an efi setup on the next 1/2 price day at pnp? I know a guy who's really good at tigging aluminum, but I don't think he'd be cheap!

Edit: I know somebody else who's fairly good and has some more metal working tools, maybe could grind it smooth? You remember the guy in slc who used to have that austin mini?

te51levin · « **Reply #18 on:** Jan 11, 2007, 12:13:54 AM »

Yeah, definately - in fact, if they are cheap enough, grab one for me too. I never get to the yards anymore. And I definately don't want to run a carbonator on that truck if I can help it.

Is it bad to stockpile parts for a vehicle you don't actually own yet?

Tice · « **Reply #19 on:** Jan 11, 2007, 02:24:55 PM »

They look damn close. I'll have to take a look at my manifold this weekend and compare. I think the port between 1 and 2 is for the thermostat. Right? As long as I can make them match up it'll be fine!

I got a friend that can weld anything, he is the welding instructor at the college! Might have to swing by his place this weekend too.

Thanks for all the info te51levin!!

Nope I dont think that the thermostat area!

Yeah, I went out and looked at it after I said that. I'm gonna find an intake for the re and have a friend weld it. Then I'm gonna start grinding on it.
