quick turbo question for a stock 1600

[coolsnake88]

i have a chance to get a good turbo from a co-worker.. (from an eclipse)
i was wondering..when it starts building boost it needs more fuel right, would slapping a 600 or 750 holley or whatever be enough without messing too much with the carb? the way i see it, the carb would be big enough to deliver the fuel when needed as long as it was jetted right or is it way more complicated than that?
im thinking draw-thru

Turbos require a bit more than will this turbo work with this Carb. Go to shoptslkforums.com and start reading. You could actually use your stock Carb if you want, its been done.

Uh, no. There's no quick answer to your question other than the carb needs to be worked a little for it to be most effective in a draw thru application. I suggest you read MO Turbo Manx's thread as he built the same motor you are considering. Read and learn, it's an interesting thread - just ignore the end where Joel Mohr hyjacked the thread.

X1000 on the hijack.

He needs to get his own thread......


It would probably depend on where you live.

I am running a blow through on a stock carb so I am more familiar with that.

Draw through has some advantages IF you have a turbo that has the correct seals in that it might be able to be done a little cheaper. I doubt it would be much cheaper if you have to buy the carb and intake.

With the stock carb all you have to do is a little jetting and some orings on the throttle shaft and if you want to use the stock fuel pump (cheaper yet) you need to boost reference it and oring the fuel pump rod.

I learned a lot and am very close now but any turbo project is going to take time to jet correctly.
I doubt there are many "KITS" that are bolt on and go....

I have a build thread if you want to read it. It has all my trials and tribulations as it happened.

I like blow through due to the fact I have no problems with intake heat.

The turbo is blowing warm air into the carb at all times and you don't have to heat the intake with the exhaust.

When you have cold weather like my climate it is worth it. My driveabilty is excellent in all weather with no intake icing.

Do a bunch of reading.... it is not a quick study and there is a fair amount of fabrication and experimenting to get it right.

It is fun though. The pull a turbo engine puts out is exciting to say the least and many drivers get an eye opening when they try to get past me in a roundabout.
I am working on a new engine build right now and can't decide whether to stay stock or go to the slip in 88 mm barrels and pistons.

hmmmmm....

i know i have to play around with the timing and jetting.. but im not looking at anything serious yet.. just wanna push a couple lbs of boost to get a little more juice to climb dunes faster..
anyone heard anything about these http://www.lowbugget.com/2_barrel_and_4_barrel_carbs.html

Im going to second turbomania. Its a great book as it walks you both through side draft draw through and blow through setups. Its a little dated, and by a little its a got one hell of an 80's vibe, but the way it breaks the general idea and process is whats great. Its actually the book that is the basis for what I know about turbos today such as calculating efficiency to plot on turbo chart etc etc.

Buy the book, then buy the parts.
