Engine Mod for 22-R

[87_Yotaman]

How can I get just a little bit more umph from my old 22-R?  I've heard a lot of different things and I want something that I can do fairly cheap.  Any help would be greatly appreciated.

Thanks

the best thing you can do is in the exhaust,  get rid of that mcdonalds straw  and run a 2 and 1/4 inch tube all the way back,  if in cali or a smog state get a big cat for like a full size truck,  dont spend extra money on a "hi flow"
the free er it flows the better  and a glass pack is best

besides that you going to need a performance cam,   www.LCEngineering.com  has excellent stuff

I forgot to add that I already have a 2 1/4 inch custom flowmaster duel exhaust and a K&N air filter.

do a intake mod..... improved my trucks performance a lot...... it means a new air filter though.....

[87_Yotaman]

What kind of airfilter is that?

[kyle_22r]

looks like something off a big block chevy.

typically a 22R is gonna be pretty wheezy because IT'S PROBABLY 20 YEARS OLD WITH 200,000 MILES!  a full rebuild with a good valve job(even better with oversized valves), redone exhaust, and a good cam will make all the difference in the world.

I have a question on this setup, do you have a body-lift? If I put an airfilter that tall in my truck it would get crushed when I tryed to close my hood. If you do you should warn that a body-lift would be required to fit that monster under the hood.

[kneedownnate]

Strange but true: I've gone from having a dirty, clogged up stock setup to having no filter or lid top(but only for about a year) to having probably the tallest one I could, with a setup like Jim's and had ABSOLUTELY NO DIFFERENCE in performance.  My truck has always been subjected to the same routine with every setup so if there were gains to be had I would have seen them.  I just don't think our little engines are terribly responsive to intake mods unless you have an actual need for that much extra air coming in.

Get rid of the dual exhaust, you need some backpressure with these little motors.

i do have a 3" bodylift.... but beleive it or not, i still have about 2" of hood clearance..... i have never poked a hole through the hood.....


that mod was actually told to me by a guy on yotatech that did it, and i dont think he had a bodylift... on a regualr truck you can pretty much do a double stack on it...... every little bit mroe of air helps...... sure its sucking engine bay air, but my engine bay is sooo open, that its getting pretty much ambient air temp when im moving.....

the filter is a fram, i jsut went to kragens looked up the part for the stock one, grabbed it, and started comparing it until i found one that was the same diamter and way tall.....

just a little bit more umph for fairley cheap.

call NWOR.  (even though i hate them) but they are the only ones i know of that have this.

it's a distributor mechanical advance recurve spring.  it costs like 12 bucks and gives you a little more umph.






if you want more power from your moter: first get a header. (LC is the best IMO,) then cam (enginebilder.com 268 torker is the best IMO,) then get a weber with the fancey air filter.  (this is power for rock crawling)

any more than that you neeed to tear apart your motor and spend some cash.

[jimbo74]

just something i relaized in refernece to someone saying the setup like mine had no difference in power, i have an exhuast on my truck, hi flow cat to flowmaster 40 with a turndown, and have tweaked the timing and bumped up the mixture screw

[kneedownnate]

Funny, cause the guy saying it(me) has a header with 2.5" exhaust(no cat), weber 32/36 adjusted nearly nuetral for power/mileage and stock timing.  My truck pings lightly under load, so messing with the timing is not wise for me, and having once advanced on it's own several degrees without a difference in power I can't see playing with it.  It wasn't an " I don't think it will work" comment, it's an " I know it won't" comment based on experience.  Obviously everbody's setups will yield a different return on performance, but due to the aftermarket skewing people's ideas on power, there's a lot more emphasis put on intake than needs to be.  Usually.  Some engines respond incredibly well to air filters, like a lot of american cars/trucks, but none of my toyotas has seemed to care very much what air filter was in it, or even if it's dirty.

if you are refering to the "distributor mechanical advance recurve spring," it does not advance your timing more. 

it advances the timing at a lower rpm.  it is essentually a softer spring that allows the weights to spin outward sooner.

you would have to modifiey the stops, that the mechanical advance weights hit at full advance, in order to bring the full advance up higher.

[kneedownnate]

No no, I know what you're talkin about, and will eventually order a couple of them.  I was commenting on jim saying he'd advanced his timing some.

This reply is a little late but,  You should save some money for awhile and install a MSD and the Davis DUI dist.  This little gem will let you tach out to 6 or 7 grand.  I love mine and I always wonder why I did not do it sooner.

[8D3TOY]

I did the double stack air filter on my 100% stock 210k mi. 83 22r easy mod cheap and a noticable pick up on power & a bit more mileage, no issues with hood clearance either.

No man, it is not to late at'tal i have been waiting for someone to revive a topic like this because i need help...i have a 1985 22-R enigine that has recently had the top end rebuilt because of a blown head gasket and a hole in the timing cover.  And yesterday i drove to Shelby and it was all i could do to go 60 mph and it took just under a half a tank of gas to drive 45 miles on the highway.  This is dumphounding me and any help would be appreiciated

Thanks,
Alex

[4inchToyotas]

wow..45miles for half tank, that's not good. Did you do a stock rebuild on the top end? even the stocker should be getting at least 75 miles for the half tank (I think). I'm getting almost 20 around town..but mine is a bit different than a stock 20 or 22r.. hehe

[79coyotefrg]

if thaT 85 block is actually a "tall" block {11.280"}  then add a 20R head on it but most likely it is the newer laser block with the shorter deck height  11.080   instead of the early 11.280
