weber 32/36 or 38???

[awhotrods]

I need a new carb for my 82 22R, and want something that will improve performance and driveability but will still run on the con.  What is a better setup for high angles? 32/36 or a 38 carb?  Also, who makes the best adapter?  Redline or Downey?  Thanks

[mr4x42u]

I think the 32/36 would be a better carb,,but you will also need a pressure regulator,,(a good one) and lower you float a bit as well as vent your over flow out of the air cleaner so extra fuel won't dump into the carb..why are you replacing the toy carb??

[awhotrods]

my stock carb isn't working too great, and its not adjustable.  I have a cam and header, so I would like to get a better carb also.  It would also be nice to eliminate the rats nest of vaccum hoses and wiring for the stock setup.  The reason I'm not sure which carb to go with is I heard the 38mm will flood out on inclines, where the 32/36 will work better.  I also have heard that the downey adapter is better than the redline, but am not sure.  I really need some guidance on this. 

[mr4x42u]

well I would go 32/36but like I said,,with out doing the otherstuff posted above,,its going to suck..the stock carb is ajustable,,The mixture screw is pluged at the factory and capped off,,you have to knock the cap out to ajust the micture..

Honestly if it was me,,by the time you spend money on a carb,regulator,adaptor,and what not you could get a throttle body injection system for a few dollars more..holley,eldebrock and I think a few others make nice little tbi systems that are basic and cheap with all the benifits of fuel injection..there about 500bucks give or take..
a new carb it 250$ a good high quality regulator is 100,the adapter is 25,,,all prices may be high or low but you see my point..check out jegs on line,,they havve all kinds of cool stuff that will work..

[awhotrods]

so who sells a tbi kit, and where can I find one?  Its looking like its going to cost around $500 for the carb setup, so I might consider the tbi.

[yoderboy]

its hard to beat the factory efi IMO

[79coyotefrg]

from what ive heard if you want performance go with a weber, if you want hi angles stay with aisin,  LCengineering makes a modified aisin for racers,  maybe that would be a good compromise

[79coyotefrg]

a stock 20R head on a stock 22block with a 32/36 makes about140hp

if i  did the major rock climbing i might go with a modified toyota efi on a 20R head,  but trails and mud and just all out HP   is what i like

[kneedownnate]

Glen,  wow, didn't know I was runnin 140 horse!  I had it figured at a lot closer to 100, give or take,   Nate

[79coyotefrg]

nate sometime when its  warm  at least 70 degrees check the humidity  and then run a compression test,  i bet you'll have 185 or better

[79coyotefrg]

i know befor mine ate the valve it was at the very least 160-170

but understand your real power lies above 3500rpm

[79coyotefrg]

i talked with Carl at LCeng  and he said my problem was not notching because at 7000 rpm my valves floated a bit which caused the impact, and destruction, 

i'm getting the dual springs from him , haveing 22valve seats and ss valves installed in a 20 head,   with my LC stageII race Cam and porting,    the custom 1 1/2 headers , 94mm pistons , crank scraper, recurve spring for dist and open kernel "splitfire" HOT plugs    i  should be at 185 +

[79coyotefrg]

Glen, wow, didn't know I was runnin 140 horse! I had it figured at a lot closer to 100, give or take, Nate

you are running a header and 2 1/4 exhaust right,  if not thats what you need for the 140

[kneedownnate]

yea, close enough

[awhotrods]

I talked to a guy over at LC engineering, he said they sell the 38mm carb to all their rock crawler customers.  He said I would not like the 32/36 and it would offer no gains.  I have also heard from somewhere else that the 38 will flood out and run bad in a rock crawler.  Who the hell do I listen to??   

[Thumper]

I would listen too the people on here more then i would some salesman from lc i hate lc parts there 94 mm kits and crap suck a$$ and they dont stand up too there products my buddy bought about 2500 bucks worth of crap from them and i do mean crap the 94mm kit the pistions suck and crack or burn a hole or like his shatter apart and ruin everything! the only thing he liked was the adjustable timing gear.
i would stay away from them, and would listin too people on here more then them because all they wanna do is tell u ya the 38 is better because its 200 bucks morethen the 32/36 so its more money for them.

If your wanting a 32/36 ive got one that comes with the chrome filter crap on top and the 22r adapter plate and the plates been smoothed too flow better. ill sell it all for 175.00
ive got pics in the for sale section under weber and hp for sale.
thanks

All I can give you is what I've seen inmy own truck. 83 22R weber 32/36. now I don't get it up on end like some do, it's my DD. but I take it up 4X4 roads hunting ect. never had a bit of truble with my carb. and it runs better than did my stock carb.
as for power, I can get the vac. gage down to 0 at any rpm I want. and if you can do that its hard to say if you'll flow more
CFM just cuz the hole's bigger.  as 0 vac. is preaty much max out on draw. I've got the LC's max size pistons,mild cam,over sized exh valves and a header. I trun it about 4800 max.  now if you go higher then this maybe  a bigger carb would help.
butt unless your realy smoking I think the 32/36 it enuf carb for a nicly built 22R.  my

go to    www.jegs.com  and look for fuel injection ..your going to want somthing around 450cfm ...

it is hard to beat the toyota efi,,its a great system,,off road soultions sells a stand alone wire harness for 350 that makes this set up super clean,easy and fast..you could go this route for an easy 500 bucks...if your good at wireing you could save 350bucks right there..
I just like how simple the tbi is over the toyota tpi..Its alot more easy to work on my truck with out the tpi plenium..

[kyle_22r]

never had a problem with LC engineering, myself.

tbi is pretty pointless on a 22R, since the 22RE manifold will bolt on to all but a few blocks.  if you're dead set on aftermarket fuel injection it can be had for less than a TBI kit, and can use the 22RE manifold.  now, a 20R is a bit different story...

[awhotrods]

ok, I just got a complete 22re intake setup.  all i need is the maf, ecu, and the harness from offroad solutions.  Anyone have any of these parts?

[kneedownnate]

Kyle,  if you have a story about making the efi work on a 20r head please share it, I need to know!   Nate

[bluetoy84]

I think you are making the right choice by swapping to EFI. I've had a Weber 32/36 and a 38mm and both were good carbs. But...
I just converted my '84 to EFI and it is one of the best mods I've made. Way more power than either carb and no more flooding on
steep inclines .

If you are planning on using off-road solutions' harness , you will need the complete efi system off an '89 to '95 22re including the engine harness . Give them a call and they will fax you a list of all the parts you will need.( it's a lot more than you think ) The best thing to do is find a donor truck and rob all of your parts off of one vehicle , so that you know everything will work together. Another thing you need to consider is, what are you going to do for a fuel pump? If your '82 is a shortbed I don't think the gas tank out of an efi truck will work. If I'm correct the 1st gen shortbeds had a lot smaller gas tank. You can use a frame mounted pump but i don't know what a good one costs. After you pay $400 for a harness plus all of the little things you didn't think you needed you might be out of some serious $$$$$$$$$$$$$

I would try to wire in the factory 22re harness  before I spent $400 on one from ORS. The harness they sell is very misleading , it does not include any of the engine compartment wiring. Check it out good before you waste your money.

If you decide this is more than you want to tackle , I would save my money and find a good Aisin carb. I wasted a lot of money on the webers and ended up going back with the stock Aisin before I swapped to efi.

Good Luck !!

I just like how simple the tbi is compared to the toy injection,,the tbi makes it much more simple to work on..But yea,,its all easy to do no matter how you go,,and you will be much more happy with the $$ you spend on injection over a carb..

[kyle_22r]

Kyle,  if you have a story about making the efi work on a 20r head please share it, I need to know!   Nate

i did some research on the subject, and came up with some ideas:

use a 22R head on it
pros - it's cheap and (relatively)easy
cons - the 20R already has 8.4:1 compression and you just made it even lower with the 22R head!

make an adapter and use an early 80s chevy cavalier throttle body and wiring
pros - probably unbelievably cheap if you can find one, very simple as only sensors were water temp and map
cons - you'd be using a 20something year old GM computer, ecu is probably not too fine tuned for truck use

go with weber TBI kit
pros - everything's included
cons - price($2000 or so), you have to fine tune everything yourself

[kneedownnate]

Pros; I already have a hybrid in my truck and you couldn't pay me to stuff a 22r head back in it, let alone willingly lose compression.  I also already have all the efi stuff, and presumably just need to make an adapter to mate the plenum to my head.

Cons; I'd be using something that came off a cavalier, and that just aint right!  Also, we've been using the weber tbi kit at work and I'm not totally confident in it's reliability yet.

I know there are people out there runnin the toy efi on a hybrid, I've just yet to be able to track one down to find out what I need to do, and I thought maybe juding by your response you mighta had some info on it.  Thanks though,   Nate

[79coyotefrg]

nate,   remember the 20R head has that extra water port for coolant flow thru the intake ,    wouldnt it be easier to fab injectors and a air plenum onto a 20R intake?

[kneedownnate]

Didin't know that, the efi stuff is still on the engine so I haven't been able to lay it on the bench next to a 20r manifold.  I might sell that engine and use my NOS Holley 4bbl manifold and a 390 carb if I can find a decent one cheap enough, but if not that'll end up on the hybrid in the 2wd.  I dunno if all that would be easier, but you never really know till you have all the parts in front of you and the time and funding to experiment,   Nate

[kyle_22r]

nate,   remember the 20R head has that extra water port for coolant flow thru the intake ,    wouldnt it be easier to fab injectors and a air plenum onto a 20R intake?

it would be easier to just fab your own intake.  there's some pics of a homeade 20R MPFI intake on SDS efi's site(i think).  basically made the main part of it out of a piece of 4" tube with a throttle body(mustang?) on the end, had 4 round runners that go to the manifold.  seems the hardest part about it is having injector bosses machined out of bar stock(they need to be chamfered and have an indent for an o-ring)
