Author Topic: 20R on propane (Read 17164 times)

I have a 20R that I am contemplating on putting in my samurai and using propane, but I am wondering if any one has any idea how much power this setup would make?

I have also been reading on the 20R/22R hybrid and it sounds like this would work pretty good with propane, Would there be any problems with having the head shaved down for higher compression to utilize the high octane of propane?

If I am going to do a motor swap I would like to ATLEAST double my current power(65hp)
but I want good low end power too and I was just basicly wondering if this setup is for me

thanks

hey jeff,

the 20/22 hybrid with 10:1 pistons and propane would make that sammy skooooot

Hey, thanks for the card!

Also anyone know of any toyota cars that used aluminum blocks that would adapt to a truck tranny and be a desent canidate for a swap? I really wanna stay light here

They are 10:1 on a stock 22R? so that would make them like 12:1 with the 20R head?

putting on a 20R head doesn't raise your compression. that's a common myth, the big advantage is that the intake ports are of a better design that yields better throttle response and high end horsepower.

the 20R only has about 8.4:1 compression on it stock compared to 9:1 like an early 22R or 9.5:1 like a late 22R. i'd build an engine with 10: or even 11:1 pistons if it's gonna be a propane only mill -- propane is something like 110 octane so you'll have no problems with pinging.

stock 20 is 8.4 or stock early 22 is 9.1 like kyle said, but when you shave the 20 head like mine is and put it on the 22 you can get 9.5 :1 or 9.7

to gett more you need some popup pistons, from like downey or LCeng

up to 12;1

I love it when people say Toyota and horsepower in the same sentance. It makes me chuckle. Toy motors were not made to be real horsepower monsters, they were meant to last a long time and be reliable. Propane would be a good setup to run more compression, but you better be keeping off the streets! I was considering propane but realized it wasn't worth it for me.

if you only knew my young friend

from toysport.com

The 22RTE Turbo engine was based on the later model 22RE (short block /tall head). This is a similar but entirely different block and head. The block was drilled with different oil passages to accommodate the Turbo oil requirements. The cylinder head's combustion chamber had a different shape. The piston was dished. Advertised horsepower was 145. The factory set the boost at 5.5-6 pounds, but completely stock internals survived boosts of up to 17-22 pounds, with proper fuel injection modifications. This is a testimony to the bulletproof bottom end design. Nitro / Methanol fueled dragsters, producing in excess of 1100 HP- used the original (modified) crankshafts and TOYSPORT pistons

In 1985 Toysport raced a 22RE Toyota Celica GTS in the Macao Grand Prix. The original plan was to use an 18RG, but since the vehicle had US serial #'s (from Toyota Motorsport) we were forced to use the U.S. engine the 22RE! To the entertainment of the other Toyota Teams from Japan, we qualified at the last minute, in the last half of the grid. The other Celicas (with their Twin Cams) were all in the top 6 positions. At the finish the Toysport Celica placed 3rd- behind 2 BMW Motorsport prepared 6 cylinder BMWs! This is the highest finish achieved by the 22RE in international racing competition.

From 1984 to 1989 Toysport prepared a Spec-Engine for SCORE / HDRA Toyota private entrants. The winnings from the Toyota Contingency Program testify to the racing capability of the set-up. The engine package kit is still available, as complete engines. This set-up won National Championships for Toyota in Class 7 and Class 7 4WD. The carbureted engines developed 185-195 HP, but consistently out ran the 239-240 HP Ford engines in the same class. The secret is in the torquey characteristics of the power band. The limiting factor of this engine is also its strongest point. The long stroke limits RPM capability to about 6200 maximum, but the bottom end will take a lot of abuse. The crankshaft is forged.

79coyotefrg · « **Reply #14 on:** Dec 21, 2005, 09:15:45 AM »

The 22RTE needs forged pistons for any serious performance upgrade. The CT26 Supra Turbo (not the MR2/AllTrac) can be installed with minor fabrication. With boost controller, upgraded fuel delivery, 3" exhaust system, and intercooler- the 22RTE will put out in excess of 350HP, at about 25 psi!

wa4x4 · « **Reply #15 on:** Dec 21, 2005, 09:22:42 AM »

For about 3,000 miles. I like toyotas because they learned a long time ago how to make a reliable car with good mpg. Not 400 hp. I drive a car daily with over 240hp and I love the power, just with AWD.

kyle_22r · « **Reply #16 on:** Dec 21, 2005, 09:58:30 AM »

if toy engines weren't made to put out power, who broke the rule and invented the 18R-G, the 7M-GTE, the 4A-GZE, and the 2J-ZE?

my hybrid will outrun a lot of things, but is still a very reliable mill.

im right there with ya Kyle, i can spank butt on most any S10 or ranger and at freeway speed, i can go from 70-90 in the distance it takes to pass a bigrig

Whats that out of?

So if I wanna run a 22/20R I should have the head shaved and get like 11:1 pistons?

About how much are pistons?

Would it even be worth it to do all this and not rebuild the rest of the engine?

wiseco 12:1 pistons are a bit pricey, aroung $100 each, you can get Plenty of power to fly in that sammy with a stock 20R head on a stock 22R block, easy 100HP right there, compared to the 1.3 sammy at 60HP

Sorry but it's hard for me to think of a wheeler toyota as fast at all. When was the last time you guys saw upwards of 130 in your trucks. I rest my case.

wa, i broke the speedo cable on my rig twice

79coyotefrg · « **Reply #27 on:** Dec 23, 2005, 09:22:24 AM »

thats the main reason ive kept my truck low , for interstate running

i kept my 4.37's for that reason too, if i need lower gears i can add a nother case

kyle_22r · « **Reply #28 on:** Dec 23, 2005, 02:27:15 PM »

i don't necessarily consider having a high top speed fast. in fact i don't go much over 70 on a dry warm day in my truck since it's scary at that speed.

however, acceleration is king, and my truck has a ton of that.

Well we are not saying fast compared to your sports car just fast compared to other toyotas.
Besides I dont consider your car fast anyway, my friend has a modified STI pushing close 400hp that would make your WRX look like it had a 22R and push 170mph but that is different standards, there are also tons of cars that will make his car look like a toy, I rest MY case
