I am getting ready to turbo my 1.8L engine. And I already know that you can't turbo a 914. But, what i would like to know is what are good cars to get turbo's off of?

I am looking for a small turbo that will spool quickly. Looking to run about 7 to 10 pounds of boost.

What turbo'd cars will give me a good turbo to use? I have been looking for ones on ebay, but don't really want to buy one there. I don't mind buying a used one, so going to the junkyard and getting one is definitely an option.

Which turbo?

I would think something matched to your displacement, a VW Beetle turbo or an audi TT they both are 1.8 or 2.0's. Your going to have to do something about getting it more fuel on boost and retarding the timing. (IMG:style_emoticons/default/confused24.gif)

Check out the other turbo T'4's on this board.

I'm not the guy with the answer but I do know it isn't quite that easy. An early 944 turbo SUCKS ass. They have a lot of lag. When the turbo S came out the hot side was changed and the impeller was also changed, giving it a much quicker spool and adding some additional power. The turbo needs to be spec'd and matched to where you want the power much like any other engine component

I think i have read all the turbo stuff there is on this site, lots of different setups and ideas. I plan on a draw-through setup, not blow through. Blow-through is much more complicated, and i won't be running high boost, so no need for an intercooler. So....draw-through seems to be the best setup for me.

You planning on running carbs and a turbo? side draft carb and turbo?

I sold a Garret Turbo off of a Chrysler 2.2 (from a daytona...) to someone about 9 years ago to use in a 914, IIRC they had pretty good results with it.

There are several tricks to get a turbo to spool up quickly, too. Not sure how good of ideas some of them are...

The one that comes to mind is having a granger one-way valve with the adjustable pressure spring inside. Put it inline between the pressure source and the wastegate after setting it to the pressure you want your turbo to be spooled at.

I am considering using my corvair turbo and side draft carb setup some day. They are not too expensive to get. Used on a 2.7L engine originally.

I would look in the junk yard for a turbo from a Mitsubishi Eclipse.

That is me thinking outloud. I once considered doing a carb sidedraft setup.
I cant help you with that though as i've never done it.

Just wondering iamchappy, thats all.

I plan on running carb and turbo. I don't want to have to run a side draft carb becuase i have a nice set of EMPI HPMX 40's that i might be able to use. If the setup works better with side draft i would run a side draft, but if i can use one of the HPMX's or maybe even both(that would be cool, kind of like a four barrel carb) that would be the best since i already have them.

Right now i have found a guy on craigslist that is selling a turbo kit from lowbugget.com, comes with turbo(garrett T3) and other goodies. I would highly modify that kit to work, mainly i would use the turbo and the exhuast piece that goes to the turbo. The exhuast is actually made for a VW bug, but i would cut it up to use some of the flanges and tubes. The exhaust piece would be modified to run off the 914's exhaust.

I think this would be a perfect match for your drivetrain, it has a little lag but when it kicks in it should give you the extra power you are looking for. (IMG:style_emoticons/default/biggrin.gif)

My 2.0/4 is CIS injected and I changed the 944/ K-26Turbo that was on it when EvilEd built it to a NOS K-26 that was used on a few different Audi's like the 5000S 2.2

It spools up much quicker than the 944/K-26 right at 1800 rpm's and keeps pulling up to 5500 rpms were my rev limiter is set.

You also have to think about your ignition and putting a timing retard control on it so you can retard your timing under boost.

My set up has very little lag and the power is very linear, smooth and Fasssst!! (IMG:style_emoticons/default/driving.gif)

That one should kick in at about 90,000 RPM's and be good up to about 200,000 RPM's. (IMG:style_emoticons/default/smile.gif)

If you you want to run a significant level of boost you may want to run a J&S Safeguard. Knock sensing timing control that trims timing on each cylinder individually.

Hook the motor to the impiler shaft and use it for thrust.
