Basically i want to know which production car came with the smallest turbo with an internal wastegate? It will be fitted to a 470cc engine.



Thanks

-Jason

I'm thinking 1.3L sohc suzuki swift

or

firefly turbo



or the primary turbo off a FD. but can i seperate the primary turbo off the turbo assembly on a FD, and also can i still use it's internal wastegate?

you may be able to remove the second turbo off the fd

it certinly doesn't look simple. Hrm... How big is the turbo? i've never held or seen one in person. How does the FD primary compare with a S5 TII turbo?

Both the primary and secondary turbos are the same size. They are Hitachi ht-12's. The TII turbo's are ht-(something largers). You can use one of them (fd's) on a turbo project if you wish. You will have to make a turbo to manifold flange as well as a turbo to downpipe flange. I'm sure you can mount the wastegate actuator on there somewhere and get everything to work. I disassembled a set of twins and am using one of them to slap on a crappy old honda and see how it works. I've had a lot of spare time on my hands lately https://www.nopistons.com/forums/pub...#>/biggrin.png

VW passat's have the tinnies little turbo ever.

One from a Volkswagen TDI should be easy to find.

Thanks for all the suggestions, but i'm looking to find the smallest turbo. The engine is only 470cc kawazaki Z400 with big bore kit.

yeah the 1.8t audi/vw/seat k03 is mighty small



the fd turbos are about 2x the size of an fc turbo assembled

3Si turbos are very small as well......

The chevy sprint turbo, but I doubt youll find one today. I have a intercooler with blow off valve from said motor...maybe dismanteled turbo. Funny I had these sitting in the garage for awhile now, I will go take some pictures https://www.nopistons.com/forums/pub...IR#>/smile.png to entertain you guys.

Here you go.

and another

nice... that kinda looks big still no?



anyhow will be going out to the wreckers to see what will make a 400 cc single cylinder go zoom

This is a turbo off some 3 cylinder car....can't remember the name to save my life. Here it is beside my t62.

Another pic beside my apexi turbo.

Chevy sprint or suzuki forsa 1.0Liter turbo.

3000gt has small turbos.

I'm thinking it was from the suzuki.

Forget looking at it next to you single for comparison.....look at it next to your thumb nail. The compressor wheel is barely bigger than your thumb haha



I'll ask Bryan at BNR and see what he says. He's pretty much rebuilt every turbo imaginable



STEPHEN

sounds like a bike motor



you know there were production turbo bikes, just get a used turbo from one of those. Kawasaki 750 Turbo comes to mind, check out 750turbo.com.

Dodge 600 turbo. Small turbo!

These are pretty rare right?

the smallest turbo i have ever seen was off of a mazda.. it was a older one.. piston motor.. what kinda mazda was it.. **** i seen it at the junkyard when i was rippin a rotary motor out.. the compressor wheel was seriously no bigger then a quarter. oh yea it was a old mazda mx-6.. the whole trbo was about the size of a pepsi can.

THe mx-6 turbos were t25 turbos with .48 a/r ratios



acura people and civic people use them for turbo chargers.

chrystler turbos t25's not sure of hte a/r

Suzuki Cappachino, 660cc 3 cyl, the turbo assy is about as long as a cigarette. litterally. Ask the guys in Japan for a Kei Car turbo, all the yellow license plates you see in Japan are emissions friendly cars with a 660cc or less displacement engine. Suzuki Wagon R, Honda Beat, Suzuki Cappachino etc etc. Just have them look around the turbos are everywhere

I would just get a bike turbo, they shouldn't be that hard to find.

smallest turbo I'd have to say.. Check out 85-86 nissan 200SX turbos... Its a t-25 I wanna say.. I've seen donuts bigger than that thing.. its cuter than all hell.. Fisher price my first turbo and ****..

If you know anyone on a college FSAE team, Garrett's giving out turbos that many teams use on their 600cc bike engines for their formula car projects. They're GT-12s and GTV-15s.. The GTV has a VATN exhaust housing that you could probably put the -12 compressor on and have one hell of a bike turbo. Ball bearing and variable exhaust..

Although I suppose you could even buy a new one from them...
