zupmanZ28

today marks the start of my twin turbo Z prodject, im going to the local pick your parts yard to search for turbos. Is there any cars that have better turbos than another? Cars that i should stay away from? Thanks for the help, even though it'll probably be too late, im leavin in about 20 minutes....

IF it were me I would look for an early 90 turbo eclipse or 3000GT or stealth.

Eclipses, Stealths, and 3000GT's are not only too rare to find in a junkyard, but too small to be of any use even if you did.

Look for Ford Thunderbird Turbocoupes..the manual trannyed ones have bigger turbos than the autos. Look for Mercedes turbo diesels too..they are usually decent sized. Some Dodge 2.2L turbo cars have decent ones too.

Look on the turbo housings for markings. Something like "A/R .48" or ".42" or ".63". .42 is the bare minimum...maybe even too small. Ideally look for 2 with .63 stamped on the turbine housing, and .60 I think it was on the compressor housing.

Don't be afraid to raid turbo diesels too. Things like VW's, Mercedes, and off road construction equipment. The A/R is a good place to start, but also check the flow ratings on a turbo map chart. Garrett is the biggest name in turbos. Rebuild kits should be easy to find for those.

Well, nothing today. I went just looking at cars as candidates to be torn down, this was about all i found:

0 eclipse, talon, or 3000GT cars

3 Subaru turbos (looked tiny)

4 Chrysler 4 cyl. (im assuming 2.2) turbos,

didn't see any Mercedes or Volvo turbos.

Im gonna check a couple other yards before i go back though, the guy working there was a complete **** towards me, and i have a feeling if i did go there and get them, he'd charge me an arm and a leg for them. If i do go there though, it looked like the Chrysler turbos were gonna be the easiest to get off, so those will probably be the ones i get.

What about Supra turbos? I know ive seen a couple of 80's stly supras in another yard near here, would they be alright?

What about a Porsche Turbo S blower from an 88 944? theres one on eebay right now in pretty good condition.

I was up at the local yard yesterday (gotta get a door for a '91 Escort) and I took a look at the chrysler 2.2 turbos, luckily there were a ton of them because those things are TINY! It would probably take at least 4 (one for each 2 cylinders) just to make 10# of boost on a 350 LOL!

I didn't think of Mercedes, good call.

One thing you gotta look out for is pricing, the pick-your-part I go to sells every part seperate, if you just scan the pricelist it looks like "turbocharger $36.00", but when you get to the counter it adds up to about "complete turbocharger unit $100".

Still, with a $150 rebuild kit you could buy 2 used ones for the price of one new one.

Well, round two starts tomoroww, im going a bit south to another yard i know of. They have alot of ford stuff so im hoping to find a couple turbocoupe t-birds, and pull everything even slightly turbo related i can find. Im begining to lean more towards moving my radiator foward and bringing the crossover pipe in front of the car too... this is becoming a bigger prodject than i had hoped, owell.

Oh yeah, does anyone have a web address or a phone number for "the carb shop"? the carb is gonna have to get pressurized and theres not a chance that im gonna even try to bother to mess with it...

There isn't really much of anything on thier website you can use except thier phone number to call them.

The guy I talked to was very helpfull, but of course tries to press every little upgrade I didn;t really need. He quoted me something like $900 total...when the mods to pressurize the shafts was about $150 I think.

Can't you build a custom box around the entire carb then you don't have to worry about pressureizing it. Or would that be even a bigger pain? Or would that not work? Seems I read somewhere you can do that then you dont have to make any modifications to the carb except for jetting of course for the extra boost )

zupmanZ28

good point. Would enclosing the carb do the same thing?

Hey cant you use a turbo off of like a turbo disel truck, like a ford or something? becuz they should be all the same like set up wise but also they'll be larger.

yes http://msvorinich.itgo.com/oldindex.htm don't forget to turn on your popup blocker first.

How do you guys think a pair of the dodge 2.2 turbo's would work on a MAF 305TPI? It's actually in my 2wd K5 Blazer, but same deal. The only mods are bowl blends, and L98 cam. I built it to be my economical daily driver/tow truck, but I've been wanting to "get my feet wet' w/ turbos and thought this might be a good way to start...

thanks, later, justin...

I have a turbo setup I'll sell you. $2000. Comes with everything. I couldn't get it tuned right. Carb too big I think. And I got a new project to work on. A 1957 Ford Panel Van. Boost comes on fast to. As soon as I got into it I'd be at 5 psi and it would fall on it's face. I don't want to buy another carb. The costs have gotten way out of control. I have a lot of post with pics to. Do a search for my username.

bhaas - I've never met anyone who could get a good tune on an Edelbrock carb w/ no boost, none-the-less w/... just my $.02

B4Ctom1

I used to absolutely loathe edel carbs, then I tuned a few with a WB o2 on a dyno and man are they easy. The biggest problem is without the WB o2, you are forced with deciding weather it is the cruise or power that is too rich/lean. Most people guess rich when its lean, or guess power when its the cruise or vice versa to both, but that can be the case with any carb.

Man, that sucks... I though that in one of our original discussions on the thing you were talking about just getting it running with the carb and then swapping to FI...

either way, it sounds to me like you're just running out of gas... good luck.

bhaas

I know. I have run out of gas a bit. I was thinking about it tonight at work. I started this and never finished it and that's been bothering me. And actually it wouldn't take that much to get back into it. I just gotta brace the headers which I already started but ran out of wire. And about 2 hours putting it all back on. Came off in about an hour. I'm soooo close and giving up now would bug me for quite some time. But this panel van is too cool. Ad all I think it was on my carb is that it was wayyyy too rich. Or my carb is too big. Anyway. I get 5 days off next week. So I may put it back on. Will let you know.

Well, maybe set it aside a little till you’ve got more motivation/ideas.

FWIW, looking back at some of what you’ve written, I’m leaning towards that you’ve got it too rich NA, and it’s going lean under boost. I’d be very shocked if it’s going rich under boost causing it to lay down, since it should still run OK below 9:1 (N2O kits are usually jetted for about 6:1), which would be close to 50% too much fuel. The only way that is happening is if somehow you’re building up too much boost in the bowls and forcing the fuel out suddenly.
