![]() | Rear disk brakes for a 79 wagon??? | 1 | 10/29 02:05am |
![]() ![]() ![]() ![]() ![]() |
I know it's not a Honda. But I drive a '79 Toyota pickup with an odd 21-RU engine. It is too slow and I need some upgrades...what can I do? If I bore it out a little can I just add bigger rings or do I need whole new pistons? Or where can I get a weber carb for it? I need any advice to make it faster. thanks

21-RU? What the heck is that? 20R or 22R(Toyotas best engine from 76-92)is the engine you want in there.Toyota trucks kick ass!

That's what I thought, it's basically the same as a 20R, Even though it's a little weak in power, this thing can take a beating. My truck has been rolled, shot, crashed(repeatedly), is older then I am and has never given me a problem.
I just wish I could get a little more power out of it.

Heh, my dad's got an 84 SR5 with a 22R. Almost 400,000 miles on the clock. And it still runs great.

I have been looking and I keep seeing that more air is the key to more power. I was searching the web and found a small electric blower that puts about 1 pound of boost. This can be a significant gain. Because of the low boost, generally, no modifications are required. Carbs and fuel injection can handle it. Mass air flow sensor compensates in computerized vehicles. If I remember right it was about $300.

If you're not in an urban area, and you don't have to smog your pick-up, then play around with your exhaust system. If you can't run a noisy free flow system, then there's still a lot you can do. Is the catalytic converter old and clogged? What about the muffler? Free up the back pressure in the exhaust system and you'll gain some ponies. And Zippy has a good point as well- getting more air into your engine will help. Is your air filter clean? Friends of mine actually run without air filters because they think it helps give them a little extra push, but I personally wouldn't recommend it.
The most important thing to remember is to start with the simple inexpensive things like air filters and tune ups before you go throwing money after the problem. Fix all the basics and get yourself a baseline then work from there.

If you can find it....22RE(Factory 2.2 Turbo)They came in the 87'-89' 4runner and pick-ups..my brother-inlaw just got one for his 87' runner...we got the complete set-up for $1200.00 cad.

I'm currently running it without the air cover, I noticed a little difference there. Yesterday I took the whole exhaust including the cat off and replaced it with a cherry bomb, it's alot louder and I think that might draw some attention from the cops cause I live in the city. It has an O2 sensor so I think the air/fuel ratio is too lean and don't notice much of a difference.
Zippy, you talked about an air blower...Would it be possible to just make one out of an electric motor? And do I just blow it down the carb?
Thanks for the help - Jesse

I haven't actually done it yet, but I will before too long. I am going to supercharge my motor using a regenerative blower. I will get the blower from a leaf blower with a bad motor. The blower will be powered from a pully at the front of the motor. It will be a complete custom job but it should not be too difficult with the help of a dremmel, torch, tap set, and granger catalog. Yes, the system I mentioned in the earlier post is electric and relatively inexpensive. You can make one but remember it has to push a pretty good volume of air. If you don't provide enough air you could actually hurt the performance. For a custom job you actually have to educate youself a bit. I haven't done that yet. I am still in the conceive and scrounge stage of the project.

Check out this site.

I know this engine. They use it in Japan for service vehicles, and sell them to US for cheap. I had one put into my 79 SR5 Long Bed PU. Cost was only 700 bucks including the cost of the engine. I was not into cars then, so I had a shop do it. This engine is slighly smaller than the 20R but gets better milage. Rock solid parts in that engine. I had over 286K on it.
Can't add anything that others haven't already said. Good luck.

I've been driving it without the catalyst and muffler for a little while now and notice some difference. I only have a cherry bomb on it right now and you can hear me two blocks away. All of the pedestrians are yelling at me to slow down because they think I'm going faster then I am. I love it. I like this homemade turbo/supercharger idea. I might have to experiment with that.
Anyone else think this site should expand to more then just first gen honda's?
![]() ![]() ![]() ![]() ![]() |
No, just firstgenners and friends. Re: your cat, I want to mention that as a Geologist I recognize the importance of cats. If you want less exhaust restriction please go with a bigger cat and no muffler. Gives OK exhaust note, reduces back pressure, and protects the air. You can probably pick up a cat from a junkyard that was made for some big motor. It might take a bit for the cat to get up to operating temp but it will still work. You can buy bushings for the change in the exhaust pipe diameter at any parts store. Don't forget to leave on your airpump. The cat dosent do much good without it.

Is it good to have some back pressure? I heard the the less you have the better. Also, what's an airpump?
![]() ![]() ![]() ![]() ![]() |
Back pressure is good. Some of the better guys could write a thesis on it. But in general, less back pressure puts your power at higher RPMs and more back pressure puts more torque at lower RPMs. But, the more back pressure you have the more work your motor has to do in order to push the air out of the tail pipe.
An air pump is a belt driven pump that puts fresh air into the exhaust stream. This provides oxygen for the cat to use as it oxidizes any unburned fuel and plays with the NOx and SOx and other gasses. Air inlets are typically on the exhaust manifold near the head.

OH..MY...GOD! Forget about the Leaf blower! Save your money and get a set of headers with 'full' exhaust, cam, dual sidedrafts (with aircleaners), and you'll be happier than now. And if you really want to be more happy call TRD (Toyota Racing Developement) and get a stroker kit, forged pistons, yadda, yadda..
And then if you just want to go nuts and marry it, Call Downey Offroad for a Chevy V8 conversion, put a B&M 144 blower on it and 2004R tranny, Heavy torsion bars, 4wd rear axle/springs with say, 4.56:1 gears/posi and a 500 gallon drum of water in the back to keep your tires from melting. And it all fits without anyone else knowing (except for the exhaust tone and monster tires out back!!) Well I guess you could think up an excuse for the drum...

Who in their right mind is going to make and sell upgrade parts for a truck that's older then I am?
![]() ![]() ![]() ![]() ![]() |
They're tons and tons of people! A shop here in Memphis is getting over 300hp from a 22r (and that's just with carbs!) These trucks are all over the WORLD from Malaysia to Canada to South America. And the engines are probably more prominent! And they were'nt just in pick ups. That little engine made Untold millions for Toyota. If you would go back and look at the Baja races, those pickups were raced from the beginning, with all sorts of High performance parts back when it (wasn't) cool to have a Jap truck. (I guess you were'nt around then... Are you younger than Our friend AndersEn?)
And I've seen early celica's that were built up and beating/supprising the heck out of people. You could get a very wide variety of rear gear ratios and posi units also. If it were not for my older brothers having accords and civics I'd probably be driving a early celica or corolla. (they certainly have more performance parts available for the early ones, and swaps are easier!)
![]() ![]() ![]() ![]() ![]() |
k, so where do I get these carbs?
![]() ![]() ![]() ![]() ![]() |
look up www.racetep.com and see if they have the manifold/carb or dual carb setup.
Fast Freddy's, or call weber and ask for the nearest dealer. (i'll do some lookin to)
It's all 'how much you want to spend! And even try looking up Grass Roots Motorsports mag, and look through thier add section for Toyota performance stuff.
It may take a little diggin but high performance stuff for them is easier to find than old Honda stuff
![]() ![]() ![]() ![]() ![]() |
Something else to add...
the cooler the air going into the carb...the higher the power...
I've been told that with each degree cooler the air is...its about +1 HP added. so try and get some outside air in instead of air from the engine bay which is prolley like 30 celcius or something...

once my dad and i had the idea of putting a gas powered leaf blower onto his civic (91 Si w/ B16A gsr rear discs and accord wagon calipers and rotors) we put the blower on the intake and took the hood off because we couldnt close it ;) and then we drove to the dyno... got 3 extra ponies but also 6 lbs of torque... the volume of the air is not important it is the pressure at which it is entering the intake manifold that matters
i.e. lbs of boost being the pressure
just a thought
![]() ![]() ![]() ![]() ![]() |
volume and pressure are the same thing in this situation...the more pressure...the more volume. The main thing is to get as much air in the combustion chamber as posible
![]() ![]() ![]() ![]() ![]() |
I haven't tested it but I figured a leaf blower could probably give near 5 psi at 200 scfm. The 200 mph blowers produce 400 scfm at essentially atmospheric pressure. Daniel, do you know the specs of the blower you used. You are correct, you can blow atmospheric pressure air at the intake and it won't do a thing. PSI increases the quantity of air entering the system.

Oh well,.... I tried!
![]() ![]() ![]() ![]() ![]() |
hey wwjessedo...howz your toyota doin now?
have you done anything with it eventually?
![]() ![]() ![]() ![]() ![]() |
Save Yourself some money and build a full race spec engine?!?! If I quit every time someone said it couldn't be done, I'd have to erase all my best accomplishments. Any innovation is met with nay sayers. A lot of innovations fail, but trying is most of the fun anyway. Were the Wright brothers wasting their time. I mean who in the hell actually believed you could make a flying machine. Everything on this site is discovered by someone doing something others would call a waste of time. Who would guess how easy it is to change engine parts between models. Who would believe you could overbore a 1200 block by 2mm. Is the idea with the 1500 crank going to work. Who knows but it is an interesting idea. I can tell you one thing, if you never try an idea nothing will ever be accomplished. If my idea works we could all be supercharged for about $200. So there!
Roger
![]() ![]() ![]() ![]() ![]() |
I need a motor to blow the air, I have an electric pressure washer. Can that be used to create any pressure?
Zippy, nice post. Didn't know about the boring over of 2mm. What's the idea behind the 1500crank?
I tried taking off the exhaust and catalyst but am putting it back on...I need the back pressure. When the engine is cold there isn't enough power to keep it idling properly.
Also, I never expected this post to get so big.
![]() ![]() ![]() ![]() ![]() |
the pressure in the pressure water is generated from when the turbine spins it spins the water pretty darn fast... but if you tried to use air instead it would spin freely (not moving anything)and not do anything
at least im pretty sure thats how it works
![]() ![]() ![]() ![]() ![]() |
(?)
![]() ![]() ![]() ![]() ![]() |
Yeah, water pumps pump water. The thing is you need volume and pressure for the air. A fan gives volume but no pressure. A compressor gives pressure but no volume. Only a few types of pumps give both. Do a supercharger search on yahoo to get an idea of what types of pumps are suitable.
The 2mm overbore is necessary to use pistons from a 1500 (74mm) vs the 72mm pistons in the 1200, 1300, and Goldwing motors. Putting the 1500 crank in the 1200 motor is discussed in a post titled Torque Monster (I think).
Natcho said to make sure everything else is ok before you start modifying the motor. Errol pointed out that there are proven bolt-on methods for getting more power and that you might want to try those first. They include headers, intake, carbs, and cams.

Another testament to Toyota quality. Today I took two truckloads of dirt, and made a ramp about three feet high. I ran my truck off of it and did a nose dive. The truck hit the ground so hard the rear bumper hit the ground. When I hit, I expected the window to break or atleast something to give in. It's also been in a rollover. I'm taking pictures next time I do this.
All insults aside, she still runs like a champ.
![]() ![]() ![]() ![]() ![]() |
hehe...why would you do that?
do you not want the truck anymore...hehe...
I bet it was cool though
![]() ![]() ![]() ![]() ![]() |
Yeah, it was great. Sorry, it's still my daily commuter car, so I still need it. I'm probably going to add another couple truck loads of dirt to it today.
On a Honda related note, I found a Honda 600 with a roll bar already installed, with two extra parts engines. Going to check it out today.

yippee .. back to hondas!
i was startin' to get a resentment !!
i'm trying to convince my girlfriend that a civic done up right can be JUST as cool as her 85 celica gts!! .. doesn't help that every time i'm online she peers over my shoulder to see a TOYOTA thread!! teehee ..
cheers
