I've been putting alot of time into my truck. (91 standard cab 22re)Frist I rebuilt the motor. Next got headers. Was really disappointed so I stepped it up and got cam from crane. Real big disappointment, I ordered a 280 grind and got a 260. This was a big pain in the you know what because I had taken the head apart and noticed as I was putting the dang thing in that it wasn't the right grind. So I made the call and they said they sent what I ordered and wouldn't send the right one I really ordered. I got stuck with the little one. Well think the cam was better then stock I pushed forward and finished the work. By this time I was losing faith in the 22re. A friend of mine told me that I might feel alot more gain in power if I got the K&N intake because I had the headers, the cam, so I need to get more flow. The intake didn't help. So the next project is to port the head. I have a junk head and started porting any help would be great.

welcome to YT.

the K&N CAI is mostly a waste unless you spend all your time above 3500-4000 rpm... and even then, better gearing on a stock truck would probably kick it.
it takes pretty radical changes to a 22re to make a lot of power. a cam and header might add 15hp or so. not that you won't feel the difference, you should, but it's not a lot. porting the head's not going to do a lot for you either, maybe a few more ponies considering the cam you have. you might be able to find a few ponies getting the air flow meter dialed in better for you, or maybe swapping in a supra afm.

you're dealing with a fairly long stroke engine so they don't like to rev high and head mods don't do alot to help.

im gona be honest with all the time and money ive put into mine i look back and say to myself why didint i just swap for a v-6, sorry bro

Gears.

TOYOTA 1

i know you just didnt say that

key word "fairly".... and i thought head work is half the battle when it comes to building horsepower/torque?

also,the 22re is capable of rpms well past the 7,000 rpm range..

i mean stock it turns 6k no problem and loves it.

to the op.. if you want any sort of good horse power out of a 22re, be prepared to spend a crap load of money.

abecedarian

yeah, I did....it is for many engines, but the engine is almost as well balanced, torque to horsepower wise, as it can be. Higher compression is about the only way you can raise the power without sacrificing the low end torque. The long stroke is what gives the 22re what torque it has.never said it couldn't or wouldn't. but asking it to do so and make power up that high kills the bottom end torque, turning it into a race engine.yup.

TOYOTA 1

i agree you cant really build good power @ low rpm's. unless its diesel.

TOYOTA 1

i agree, though high rpm's will fix that, i think he wants a race engine lol...

abecedarian

and what's a diesel engine have that a gas engine doesn't?
compression ratio.

TOYOTA 1

yes, but dont forget about the mile long stroke also! witch keeps them from building power @ high r's.

abecedarian

not trying to turn this into an argument, but diesel has a fairly slow combustion rate when compared to gasoline... that limits rpms.
there have been diesel engines that spin in excess of 5000 to 9000 rpms and nearly all of them use a pre-combustion chamber to pre-heat the fuel so it can burn fast enough for high rpms, coupled with a relatively short stroke. my 83 VW Quantum Turbo Diesel would spin 5500 rpms... smoked a lot, but would do it. cummins built diesel engines for Indy car racing a while back.

and lets not forget the venerable Cox .049 engine... which can run on diesel and rev to over 10000 rpms.

TOYOTA 1

argument? i prefer to call it a technical discussion

stroke has allot to do with rpm's, most common Diesel's have a long stroke witch also limits there rpm's correct?

10,000 rpm, ill bet it has a short stroke..

my point here is that if you want to build good horsepower out of a 22re, its gonna be done @high rpm's.. and without head work you not gonna do much!

ok my .02 is spent

abecedarian

hehe.most, maybe. but to say diesel engines' rpms are limited by long stroke is not always true. the long stroke does allow a diesel engine to more completely combust and produce maximal power, but it does not limit the rpms, per se. if the fuel can start combusting before it actually exerts force on the piston, rpms can be raisedyeah, the cox 049 engine has a piston not much larger than a pencil eraser, and a stroke to match.which agrees with me saying you're going to be making a race engine. anything more than 150-200 hp or so from a 22re, is going to be killing the bottom end so much you can't easily drive it on the street.

and people wonder why they didn't make 16v heads for them?

dave22rte

So finish the port job, put it back together see what happens

Diesel engine reving to 9780rpm.

Didn't know the Cox 0.049 could run on diesel.

dave22rte

I have a 22rte sitting in the shop complete waiting to be swaped. Good idea or no. I think I will still run in to the same problem. Disappontment with the prefomance of the 22rte 22re motor.

abecedarian

it can. not really enough lubricity in diesel though to keep it running very long, with the cox engine being two stroke, air cooled, and lubed by the fuel.

algranger

the 22ret will dissapoint you too. just swap for a 3.4 v6

abecedarian

you'll notice a difference between the 22rte and the 22re, but not much if you're using the 22re ecu.
in their own worlds, the 22re will produce more torque than the 22rte up to about 1500-2000 rpm, then the rte will be coming into boost and produce about 30% more horsepower.
you can finesse a 22rte to about 200 hp without major work, but you will run into some issues along the way, which amount to fuel delivery and mixture management.

have fun.

I have might beable to get a all=trac celica turbo motor with all the goodies. Can I put it in my truck with out cazy mods?
