Topic: 22R - 22RE Heads - whats the difference?

[Toyoballs]

  :yupyup:I'm going to start my EFI conversion today but read in one of the threads here something about 22R and 22RE heads being different If so - whats the difference I've got a 84 22R that I'm converting and am going to use a LC Stage 1 EFI cam with new OEM rockers

Also, Idon't think this block has a boss on it for the Ping sensor to thread into any Idea's that'll work
I'm also going to try this without removing the head  :sonic: Do it when it's cold and loosen everthing before the head bolts are and I should be in like flynn

i think you would just need a efi intake, but to be sure you might want to ask marlin, or carl at LC since thats were you'll get your parts

[brainlessfool]

drain the water too, 22r and 22re heads are diff.  but not sure if it will keep you from putting on a efi intake, don't think so but?

[Toyoballs [OP]]

Thanks guys, I've had the cam and rockers and a donner vehicle for a couple of months already and have done a bunch of research.  so now it's time to do the job. Through everything that I can find, the head is the same just a different cam, dist, intake - etc but as far as I can tell takes the same head - I wanted to know what u guy's though being around Yota's WAY more than me. I'll ask Marlin or LC tomarrow... Thanks Again

I'd like to go toy EFI on my 83 too. don't think theres any problems with putting on the intake , just never realy looked into it. let me know if LC says it will go for sure! thanks:thumbs:

 :flamer:Here's what I found out so far # 1 - Tool required

[Toyoballs [OP]]

  :nerv:Just kidding
My 1984 head is going to work It's casting was setup and drilled for the EFI manifold But not all 84 heads were   If you have an older 83 - 84 engine and want to do this conversion you'll need a EFI head off of a same year Supra - they were EFI

 :headscratch:The difference in intake manifolds in this photo EFI left and Carb Right

[Toyoballs [OP]]

  :greengrin:Pretty clean for 140000 miles on engine - eeehhhh Bad news is my timing chain needs replaced - one of the guides was broken up - thats life

[brainlessfool]

go duel chain!  who's header is that? the air injecsion set up looks sweet!

[84runner]

So how do you tell if your carb head is drilled for a EFI intake?  And were is your beer in the tool pic?

[Toyoballs [OP]]

 :eyebrow:It's a Downey header I got it off of ebay for $180.00 never used :psss:He said it was chrome but I think it's ceramic coated I want to do dual chain but I will have to change my oil pump and front timing cover :unhappy:

So how do you tell if your carb head is drilled for a EFI intake?  And were is your beer in the tool pic?

:psss:On the photo above with my finger pointing to one of the bolt holes in the casting, if you look close you'll see other holes too that were'nt used for the carb manifold but will be for the EFI I've got a 20R head also and this side is cast much different
Buy the way I  got this 20R head and a Offen intake with a holley 4 barrel (I think it's a 390?!?) I might get rid of it, whats it worth???
PS: Being from the home of Anheuser - Busch I most defenitly consume allot while working on my Yota's - I think I drink enough to pay for Jr's tires on his Bud car

[Toyoballs [OP]]

 :thumbs:Well Fellers, Tomarrow I'll make this ordel solved
I did, by the way, decided to remove the head not trusting the gasket  I took it to the loval machine shop for recon They say my heads in great shape Hummmm - thats not what the doctors say so while I'm waiting for the head, I'm changing out the wiring harness in my rig from carb to EFI Please = don't try this at home kids

[Marlin]

To mount the knock sensor, get a 12x1.25 nut and weld it on top of one of the pass side 10x1.25 motor mount bracket bolts, (they have a 14 mm head). Reinstall the bolt and install the knock sensor. The wire is long enought to plug right in

:bowdown:Thanks Marlin, I wasn't looking forward to epoxying the sensor to the block - great idea

[84runner]

That wireing just looks like to much fun, I might have to do one myself. Make sure and take the time to soder the wire, cause the but connectors don't always work that great. If you know what I mean.  Are you doing a full swap of the harness from tail light to head light?

:eyebrow:Wiring don't scare me none No splicing if I can avoid it Replacing entire harness with 87 4 Runner harness- yea just a few extra wires, but I'm not going to diecect it

[Toyoballs [OP]]

 :smack:Oh yea, above photo, the EFI wiring harness on right - Carb harness on left
This photo is EFI wiring going into trucks dash

NICE

[Marlin]

I remember having to hole saw a new hole in the firewall on the passenger side for the EFI harness?

I've heard about that twice so far, where did you have to drill the hole at? There is already a hole about 3" dia. on the passenger side where the harness runs through along the out side of the fender well and back in by the battery for the main fuse box plug ins.  But I still have the 87 donner 4 Runner, I'll take another look at it's fire wall to be sure. I striped the harness from it in mid summer and my memery is as long as  

[84runner]

Well it looks like I can bolt an EFI intake up to my 84 carb head too. I just might have to look a little further into this

 :eyebrow:Well heres what I've learned so far...
The 84 head should be cast for the carb and EFI intake manifolds i.e. mounting bolt holes.  
I think I can run a Dual timing chain on this engine also with only changing the oil pump crankshaft drive dodad. My wiring harness is almost installed and so far I did not have to cut or drill any holes - the harness came out of a 87 4 runner and it's going into a 86 truck cab eeerrrr whats left of it anyway.  the 84 engine has pop up type pistons in it. the head is different from that of a 86 22R head - different combustion chambers - look more like a turbos head.
If you do a carb to EFI swap - Get a complete donner vehicle so you can have all the brackets EGR valve and plumbing - wiring harness and computer, just make sure your donner is all there other wise you'll be a junk yarden like I did - that's kinda fun too

Photo of wiring harness going into truck along with   YA THATS RIGHT A TILT STEERING :yipes:

[84runner]

Looks like you got your donor right next to it.  I might be following in your foot steps cause I have  a blown head gasket

[Toyoballs [OP]]

Nope, thats my buddy's 85 4 runner we're doing leaf springs, u-bolt flip kits, cross over steering w/IFS box and then installing a complete fresh 22RE rebuild - he's going to put Marlins dual cases in it next.  

 :sonic:I just got my cylinder head back and got a dual timing chain on order from LC today - got most of the wiring done but I want to clean and throw some paint on my inside fender wells first. I'm also in the process of installing a exo roll cage. we're ordering a M-Tech bender tomarrow. I'm fed up   with this HF bender, going to use it for a boat anchor or try and convert it to a press. I'm also working on a new fuel tank setup and making a anti axle wrap bar for the rear. whew...

[4.3 headache]

hey Toyoballs!! wish i had a digi-cam to show you what putting a complete 01 chevy blazer harness behind toyota dash looks like!
  I swapped in entire hrness & steering column  out of blazer completely eliminating toy harness

[84runner]

Like a I said it looks like you got a donor right there
