looking to build a 670 turbo,thinking about buying a comeplete engine with a areo 53.want to info myself up as much as possible.looking for any old kit manuals or just info that i can buy on 670 turbos-thank you for help.
670 turbo parts/literature
- Thread starter the sled shop
- Start date
I don't think anyone has any manuals or instructions on the old 670's. we just use to through parts on them.
there was such a small amount of us guys doing turbo's on sleds at the time that we just had fun and there was no rules or history for that matter. i can sure tell you any thing you want or things that we did. I can also set you up with some parts but instructions are not out there.

Flat slides
Personally I would use a flat slide carb equivalent of whats on there. I would also find an end dump pipe off an older F-2000 chassis that housed a 670 instead of that horrible side dump pipe. I might just try that, I have a nice 670x, a pile of turbo parts and a big Aero 53. It would be a fun project.

rob that would be awesome if you could photocopy that manual-i would be very interestred in reading that.im not sure what parts i will need to build this sled up,i think just some clutch stuff and maybe a racepack-the package im looking at buying is an engine and a turbo kit all together and very complete (very sharp package) with a zx chassis end dump wrapped pipe.thanks guys for all this help,its real nice knowing there is people out there willing to help-that share the same intrest.
I would be interested in this kit your buddy has - if its complete and the price is right. Thanks,

I had an aerocharged 670 back in the 90's, ran the aerocharger 53 turbo with meth injection using a automotive windshield washer tank/pump and an adjustable mikuni powerjet plumbed into the charge tube. My memory is a bit skittish on the details this is what I seem to recall. I ran sea doo center crank seals, had a special extra thick dynoport end dump pipe made and used a crankshop .047 base gasket to lower the compression some(Im a flatlander). Even with reduced compression and 6lbs of boost it didnt like pump gas, I always ran avgas or better. We also played with the turbos vane controller by adding a spacer that was about 10mm thick to make more boost, seems like we got 11 or 12 lbs that way. It was a sick lake racer but a rotten trail sled, eventually I sold the turbo setup to a guy who was going to install it on a summit to ride @ high elevation. On the lake a buddy of mine said riding the sled was like time travel... thats where TT670 came from.
