that looks pretty cool man, from the turbo where does it go from there?
 
mad man- the exhaust hasn't been fab'ed up yet but when i get to that it will go to the factory location with 1.5inch piping into a 1.5 in or so muffler. The outlet side of the turbo is going to go straight into the intake port on the head, and the carb is going to go from the inlet side of the turbo to the left side of the engine....

xpitbossx- you sir are correct, ebay it was... it ran me about $150 USD or 191 AUD shipped.... its a kp31 from a smart car...

looking good man, this is going to be sweet, get some vids and shit.


ps those smart cars look so f$king gay
 
so i was warming it up today and the turbo was working awesome, i worked out a few of the tuning bugs and it was pulling strong... then all i got was blue smoke from the tail pipe. apparently my friend who made the gaskets for me didn't put a hole where the oil feed line was, so the intake oil seal on the turbo went after about ten minutes of very little oil flowing through it. so this project is being put on hold until i can either fix this turbo or get a new one. Im bummed out, i'll post if anthing changes :(
 
thats a damm shame mate.................who is this hardafaster tool,man he just babbles crap man no idea
 
thanks turbome 4 the info..... unlucky bout the gasket....it seems u no wat ur doin so im sure ur will hav it runnin soon!.. keep ur head up ur doin good!...let us no how it goes!
cheers
 
Sorry about the bad luck but im very interested in your combo. I plain to use this same turbo but on a little larger engine. How much boost did you see before it started cutting out? Also did the engine have to rev pretty high to make boost?

Thanks for the info

it was making like 2psi then it would just cut out, i wish i had video taped it, it was pretty good til it blew the seal. Im sure the setup would benifit from a bigger engine, i may end up with like a 110cc atc engine and then bored it to like a 150cc or something like that when i can get a new turbo that is... i will keep everyone posted. Thanks for all the support

does the smart turbo run a positive oil seal on the shaft? these days most turbos off EFI/diesel motors dont run a positive seal, because they dont need to.

with a draw through setup you need that otherwise the vacuum you get around the compressor when the throttle is shut will suck the oil straight into the engine. with blow through (carb or efi) the compressor will never see that kind of vacuum so its not an issue. most oldschool turbos like garrett T04's have a positive seal because most setups had a carb mounted on the front of the turbo in the old days

you might be able to get the turbo built with a positive seal. otherwise its EFI/blow through, which is a new can of worms :cool:


im impressed that a turbo off a ~600cc engine is getting spooled by a 88cc motor tho. nice work
