It also has a very small bore size. It runs that 10.8:1 compression on regular gas, not premium. That 74mm bore makes it more detonation resistant. So let's assume that this motor is safe for roughly 9 PSI, so I need a turbo that will make about 10 Lbs/min at a pressure ratio of 1.64, something like a GT1548 or so would work well and make about 100 HP.

Old bike Racer I know has been doing it for years.. His very first turbo bike was a KZ900. Told me it took him somewhere in the neighborhood of 2 years of tinkering to get it tuned right.. His 500+rwhp Busa took him about a week to tune on his shiny new Dyno.

I helped a friend turbo a 2000 ninja 250 and it ended up being damn near quicker than my modded ZX6. We planned on using a 500R for the base bike but couldn't find one for under 1000 like the 250.

What turbo did you use?

The one I have for sale is a GT1544, I'd think it's better than the 1548 for this application. Besides better spool, it's air (and oil) cooled, with cooling fins on the bearing housing. The 1548 is watercooled; I guess you could run coolant thru it but that's just more plumbing & cost. The 1544 and 1548 are both around $525 new.

you gotta blow through a hat and have a FPR. kind of sucks if you ask me. can you stuff the R1 motor into the R6 frame? might be cheap and easy. I was in the GSXR camp for a while, and that's what a lot of the 600 guys did--put the 1L in their 600s. I rode a 750.

I don't blame TurboTim for not giving me the GT1544 super cheap (I really tried to low ball him.) So I decided to buy this instead. We'll see if it works, This would be far cooler if I purchased two of them... LMAO.

Nice. "Looks" to be the same thing as the GT1544, in terms of the turbine flanges, style & position of wastegate actuator, except the GT1544 wastegate bracket is seperate so you can clock the thing easily. And not as fancy casting on the turbine outlets though, 1544 has a tapered turbine outlet. If you can't find the flanges somewhere, I have a set (one set stays with the 1544 I'm trying to sell, the other set from the busted 1544 are sitting acting pretty in a box). Actually if you need anything else that fits that turbo (assuming it's the same), air filter, oil fittings, etc, let me know.

I assume it's chinese. Does this eBay ETDMotors have anything to do with ETD Racing?

In all honesty, I don't know why you got that instead of the one I'm selling. Mine would come with the flanges and oil fittings, air filter, plus mine is a geninuneie Garrett. Add in the cost of all the misc stuff, take off half, and offer me that. I would have taken it, especially for this project and the fact that you'll probably get it to work. But whatever no biggie I'm sure you can source that stuff cheap.

If you are successful maybe I'll do the same

EDIT FOR PICS: Flanges etc should be close, except the turbine inlet "triangle" flange is upside down compared to mine, and looks to be a little wider. Lemme know.

Weaksauce update:

Well I slapped on a set of 37mm Flat-Slide carbs and got the throttle adjusted right. These carbs came off my race bike, but they did the trick, Weaksauce accelerates fairly hard now, but really doesn't come alive until 8,000 RPM... Needs more cowbell and some boost.

For a 500 Ninja, eh, it's not too bad. Double the power and it might be fun... I had it up over 100 MPH tonight, so it's holding up ok in that respect... it's all functional.

Mark

PS - Tim, throw me a price for the accessories...

IIRC It was a GT2 off an old diesel Jeep. Spool wasn't too bad, but you had to get her wrapped up pretty high to really get some good power out of it.

This thread makes me wanna finish my turbo bike project... Too much work needed still though. Stretch the swingarm, modify the stock header, charge plumbing, Megasquizzle...

Honestly I would check on ebay to see if I could score some injection throttle bodies from an injected bike. I've seen 600RR, Gixxer, etc TB's on there pretty cheap. Suzukis been injecting their 600s since like 2000 so they're all over the place.. Just need to figure out how to remove two of those TB's from the mix... Or mix up a manifold to take 4 throttle bodies.

Now that I'm thinking about it.... Wonder if you could wedge a 600 I4 in there?

I sent you a PM before you bought that turbo with what the accessories run. If you need all of them, $80. If you only need a few things, make me an offer. I'd wait to you get the turbo to make sure the thread sizes for the oil fittings are the same. If all you need are the flanges, $40 shipped for both I guess.

I'd sell you everything with a turbo for $215+shipping.

I don't know how it would run on the stock carbs, but these carbs and a muzzy exhaust dyno'd at 60 RWHP.

I hate carbs as well. I bought a 1986 Yamaha Radian 2 years ago and spent months trying to get it working. That included 3 full sets of carbs, i assembled one good set with many new internal parts. Then once it ran I found out the clutch was bad and it didn't have compression in cylinder 3. Sold that sucker and got into the miata like I should have in the first place.
