I dunno bout that. It looks like... well... ass. It seems a shame to do something like that to a pickup that appears to be in pretty good looking shape.

 

Very cool.

He has a point about the carb being more "user friendly", no needing to mess with injectors or computers, just switch to a bigger on or bigger jets.

Not the prettiest exhaust in the world, a little too square to get optiumum flow, but talk about a money saver.

I would be curious to see how it does on an otherwise stock 22R. 9.0:1 is still pretty high to run a turbo.


oh crap...now I'm dreaming about doing this to my 78 celica once I'm "done" my pickup. A 20R with only 8.4:1 should be a good recipiant for a low boost turbo.

Darin, sorry about not getting back to you, but I'm kinda swamped right now. rather large buildup of work to get done before I can go hunting this weekend. But I'll get in touch with you as soon as I can.

 

love the pvc intake ... also it sounds like a tractor is that a good thang ?

 

A budget job that works is all that matters, I would be interested to know the kind of power your getting now too!

 

I'd say that another point that matters is how reliable it's going to be.... I don't think it's going to be very reliable...

 

Probably not, but it aint my truck.

 

tell me the pvc is in there for a mock up, and get a intercooler in there

 

I bet it rips... haha

 

Well, for the 4lbs of boost he's going to be able to run with 9:1 ompression, is an intercooler really needed?

 

Maybe I'm carb-retarded but I thought in order for a carb to work correctly it requires a certain amount of vacuum? I thought this is why when they supercharge a carb motor the blower is between the carb and the manifold? Seems to me that this thing will probably not do much more then idle. I suspect if it can actually build any boost as soon as it does the engine will buck and sputter badly. In fact I think he even says it "Doesn't like high RPMs", and he was running it with the turbo oil drain going into a bucket. Wow!

I just don't see how you could pressurize a carb and it wouldn't jack things up big time.

Not to mention fuel pressure. The fuel system on a carb motor is designed to squirt into something that is under vacuum not under pressure. So not only would he be more lean just from the additional airflow (assuming he could actually get the engine up high enough to create boost and more airflow then stock seeing as how it now has to suck air through the turbo before boost builds) but his fuel pressure would have to squirt against the whopping boost levels he will generate reducing its effectiveness greatly causing a lean condition, at best!

But honestly, I'd be surprised if that was ever an issue. I think the second it starts to build any boost the motor will sputter and won't be able to build any more boost simply because the carb can't work under pressure, only under vacuum. No gas, no RPMS. No RPMS no air. No Air no boost.

I didn't read all of it because it was starting to make my brain hurt, but from what I could tell he tried an EFI system but he had one bad injector and tossed out the entire system??

If I'm wrong, please educate me. I'm really more of an 'injectors and tuning' guy anyway..

 

Carbs can be either blow through or draw through. Vacuum or boost is irrelevant, what is relevant is the velocity of the air passing by the jet. The higher the velocity the lower the pressure generated in the nozzle of the jet. It should theoretically work. Though I still have to read up on carbs and turbos....

 

omfg - now im looking at his turbo manifold....i think im going to cry....yeah that = BAD

What the hell?? the oil lines are hoses?!?!?

EDIT:

Ok ive NEVER turbocharged a vehicle before but ive been doing tons of research on it and our family owns 3 turbo diesels that I keep up and running. (and modding one)

His turbo manifold = POO! First off IF you make turns you do them gradually not make them at 90" angles. Next you do NOT use headers. Headers are ment to scavange cylinders, a turbo header is desinged to keep the exhaust pulses hot and fast moving; ie they do the exact opposite of each other! If you fabricate a turbo manifold you use plumber's weld el's on the flange and keep the turns gradual, keep the runners separate until the turbo flange. And the whole point of individual runners is toe keep the exhaust pulses separated and he shoots himself in the foot there too! And you KNOW that turbo is a divided scroll hot side...ugg (sarcasim)

Next up is the oil supply hose, wtf is that crap?? Sorry but this is just ghetto fabulous....top rail of a fence???

Can someone PLEASE ban this guy from ever stepping foot into Ace??

ps - I think the PVC will work but ewwww. No intercooler really needed as long as he keeps the turbo working very near to its most efficient island....or keeps the boost below 7 psi.


pps - and where is the BOV?? OMG i wanna watch the first time he romps it getting up to boost, then lets off of the gas all of a sudden!! lol

 

LMAO...
I am in tears right now...
I just watch that vid...
I would be affraid to even hit the gas pedal...
My fear is that it you explode...
That or just die...
Like when I forgot to hook my MAF back up...
Would turn over and then when I hit the gas slowly fall out...
and the PVC...
Thats jsut freakin scary...

 

LOL, he said 9.0:1 is high for boost! Tell that to the 10 zillion Mustangs and Camaro's that have cast pistons and come stock with 10.5:1 engines! They can't keep supercharger kits in stock for those cars, I know, I had to wait for 3 months to get the Procharger for my Mustang. I think his compression ratio is the last thing he should be worried about!

Darin, glad to see year your still turbo Toyota exploring! What a find that's awesome, no wonder I can't sell any of my kits, LOL! I was using stainless instead of......umm, plastic and glue! How is your MS doing, still working good I hope, I still don't have a tach.....oh well. I did test it with a stock truck.....it's broke, so I'm going to go with the custom Autometer instrument cluster instead of buying a new cluster from Toyota. For now the boost is still at 17 PSI and the rev chip is 6400 RPM, just so I don't break anything for now until I can see the RPM's it's turning, it seems to hit the rev-limiter very quickly in second gear, blazing the 31 inch mudders.

Maybe I should do a in truck video, it sounds pretty bad ass, maybe that will spark some intrest for some of these guys to get a turbo kit from me and a MS from you.....

Later

 

Rick,
I'm setup. Megasquirt is working with stock ignition and I've got it completely programmed for the 22RE. It's completely self contained, no extra wires. I'll sell a few of the harnesses and I'm trying to find someone decent to assemble megasquirt correctly - I've already flunked one person out. I'm not selling turbo kits - I will sell the electronics side of it - the harness and I've got a few spares forsale, but I'm not operating a shop that does complete turbo systems.

My turbo motor is complete and ready to drop in, minus the clutch, as I ordered one for a 22RE, forgetting that I've got a 22RTE flywheel:

Your kits are great.. People need to understand that you're selling a very modern turbo, capable for some pretty serious power - I think Jeff is putting down over 300 flywheel. Your hardware + megasquirt can mean big power, even for factory 22RE's.. You've obviously got your tuning right if your motor has survived 175+ hp on the street for over 10k miles. Also - they need to compare your costs to the stuff that LC is selling - they're find that you're priced very well and your headers don't fall apart.


I'd love to get a copy of your dyno runs... I refer people to you for the hardware to make these systems go - turbos, the exhaust manifold, etc - and as an example of what a properly tuned 22RE can do.

Also - let me know what injectors you're using and send me your timing/fuel VEX files... I'll probably end up providing megasquirt to some people wanting to do turbo 22REs.

 

I meant compaired to the 7.5:1 that Toyota provides stock...but yes, point taken.

if you want to sell kits, get with the times...mandrel bent is over rated, PVC all the way

 

why not crank up the boost, with a IC you should be able to run 7-10psi (i've ran 15psi on a mazdaspeed protege with the same comp.)

 

Saying that you can run X boost with Y compression isn't a static calculation. No offense, but it's probably bad advice. The timing between the motors may not be the same, the air/fuel may not be the same, turbo efficiency may not be the same, design of the head and combustion chamber may be different.

Rick is running the highest boost I've ever heard of on a stock compression 22RE. I haven't seen his timing map, but I'll bet he's running a lot of timing retard and significant fuel to accomplish that.


Bill is right - at low boost pressures, you typically don't need an IC... Best way to tell is to be able to determine what your intake temperatures are, however.
