anyone ever seen a turbo'd toyota 4 cyl? pretty curious as to how that would work and if the engine could handle it.

The 22re engine came stock turboed for a while in 4Runners. It was named the 22ret, or 22rtec (CA spec).

If I were to take a wild educated stab at answering, I would say that the 22r can handle boost just as well, if not better than the 22re, except...you will have more trouble to get it to run good with the carb than with EFI, which might be your demise in the end.

did that 22ret engine rip? i've got a 94, i wonder how hard it would be to cram a turbo in there.

Not really, it was a stock turbo. Pretty moderate for a 22re, and definately on the low-end compared to boost today. People have modified their stock turbo setups to push over 200hp with not much trouble.

The cool thing is, 22r's are sturdy little motors and real easy to work on, besides the bunch of vacuum lines you have to connect correctly. So even if you wanted to try boosting it, it wouldn't be too costly and time consuming to build it up to a point where it could handle quite a punch.

I'd try searching the forums a little deeper, and if you come up with nothing, hit up google. I'll guarantee some results. There are many companies specializing in the destruction...uh...boosting of 22r's and 22re's.

there were turbo pick ups too 2wd and 4x4.

A turbo 22R has been done.. The most effective way to do it is via using propane (IMHO). You can do a draw through with a carb, but it's a bit of a hack and you can't intercool.

Like most mid-80s turbos, the 22RTE was very conservative. It's got very low compression and very moderate boost (7-9 psi) and a small turbo.

Turbocharging a 22re is a very cost effective way to get power out of it. I think it's the most cost effective mod you can do in terms of hp per dollar, if you're willing to do it yourself. To do it right, you need to drop the compression (22rte pistons), and run fuel mangement. Check out my webpage for more details, but at least one of these motors (Jeff Mosk) puts down 250 wheel hp in a reliable form...

Rick (www.fullboogie.net) who posts ocassionally on yotatech has an otherwise stock 22re (1994?) and he's doing 170 rwhp on pump gas.. Rich is an excellent tuner, however... And your results may vary!

I have done a Turbo 22RE conversion on my 94 4x4 toyota pickup. If you want more than 200 reliable horsepower it isn't going to be cheap, but the end result is really fun. I don't recommend turboing a stock 22re. Before I did a complete conversion on mine I just stuck a turbo on it and within 1000 miles I blew the head gasket running only 3 - 4 pounds of boost. However, built correctly, with the right fuel/spark/compression modifications the 22re can handle a turbo and produce a fun amount of horsepower. If you have any more questions about it just ask.

Rick at Fullboogie.net has had a great level of success turboing an otherwise stock 1994.. HE's the exception to the rule and he has to be very good at tuning.

A built turbo motor can put out 200-300hp on the street.. Web search "Jeff Mosk".

like dcg said, with good tuning, it can be done. keep in mind that if you don't lower the compression ratio, you should run less boost than a stock 22RTE because the extra compression will put you that much closer to detonation.

forced induction is fun, which is why i'm almost done gathering parts for my 7mgte swap.

More info:
The toyota bottom end is about as solid as they come. The rods and crank are good for more power than your driveline will be able to handle. Cast pistons are good for about 200hp, depending how who you ask.

Forged pistons are available, cost is between $300-$588, depending on brand and custom or not.

Your mileage may vary depending on how much you're playing with timing, but on a 8.5:1 motor, premium gas, I'm hitting knock at 9psi.
Someone emailed me today and said at 8:1, they hit knock at 12psi.

For reference, a naturally aspirated 22re is over 9:1.
A factory turbo 22re is somewhere between 7.5 and 7.8:1.

They really do respond well to turbos, but you need something to control fuel and spark. Simply bolting a turbo on - or buying one of those "this is all you need" ebay kits is a Very Bad Idea [TM].
