turbo kat?

[katman]

Well I pulled apart a wiseco big block and found a set of 1328cc turbo pistons. I was told it was a 1428 13.5-1 engine but guess he was wrong. So I am going to keep my eyes out for a turbo for my katana.
Anyone know of the wherabouts of one?? I am going to keep the 1260 and build a turbo motor too cuz I'm power greeeeeeeeedy.

I have four sitting in my garage, turbo's that is. All rebuilder cores though.

I am just venturing off into turbos Dink so what make are they and do you have just the turbos themselves or other parts too?

Katman, the oil supply is too low a pressure to run anything but a Rajay. For a while Rajays were built under the Rotomaster label. Rajays have a very large bearing (bushing) contact surface and can stay alive with a lot less oil pressure if they are balanced real well and get enough oil flow. I'd be happy to help a fellow member with a turbo setup.

That stinks.

Assuming your asking used, I have seen full kits on eBay from time to time. Good luck.

With couple of tricks it's possible to increase the oil pressure above 30 psi which should be enough for any turbo. The first (widely knonwn) one is the GS750 pump gears. The second one is a restrictor plug on place of the oil pressure sensor. I have run ordinary modern Garret with this setup without problems.

Another option is to use some ball bearing turbo. They should survive with very low oil pressure. But they tend to be pretty pricey.

I saw a complete running (used and on the bike) turbo setup on ebay two weeks ago. It was on a older GS It was a Rayjay as I remember and he was asking $1500. I dont know if this is a good price or not. Seems a little steep for a used turbo.

I have a few odd turbo parts hanging around too. Keep us posted when you start and take lots of pics. Herman rebuilt my turbo a few years back and it is still running great.

At idle it sounds a bit like a tl1000 with race cans and a fast idle. Cruising along it is not much louder than a gs1000 with a yosh pipe. When I pass under boost I have been told it sounds like a harrier jet with a quick misfire. One guy I ride with is a jet mechanic...

The turbo actually takes a lot of the noise out and I have no plans of changing the exhaust at all.

[katman]

I was hoping you were going to say that. I don't want to use a pipe either. it looks way cool bare out back with not pipes but I don't want it sounding like a drag bike either on the street.

very good then. Thanks.

Have you got a pic of the other side? Is your Turb a RayJay?

[Kaptain Ketchup]

Other side:


Turbo is a B25 rajay. converting to an F compressor this winter yet and EFI. I will be selling the B side stuff and the modified HSR42 with a sweet carb-to-turbo adapter when I get into the EFI conversion. Turbo housings, pipes, and the manifold were coated in Shelbourne. Ceramic for the hot side and a material that dissipates heat on the cold side and the intake manifold.

[katman]

Looks great dude. I am stoked now...

I am going to be looking for a roller bearing turbo I guess with carb not efi.

Can you list the parts I will need IE: carb, mainifold, header, turbo, wast pipe and so forth? I want to know what the complete kit consists of.

have you made any mods to the motor?? studs or anything other than turbo pistons? Are the cams special?

[Kaptain Ketchup]

Blow/Draw through? I had a lot of work done to my motor. Quite a long list of internal upgrades and lots of time and money spent. 1100 turbo pistons, gs billet basket and 1100 ratio straight cut gears on trued/welded crank, kawi shim under buckets and lots of other head work, etc....

Some pics during the build.






Most of my build pics are over at

You'll need:
All the plumbing (exhaust pipes and boost safe intake stuff that sees pressure) and all related hoses/lines, turbo, carb of sorts, fuel pump, fuel regulator, wastegate, BOV (if running blow thorough), decent ignition, deep pockets....

[katman]

kool, What I meant was anything inparticular just needed for the turbo. I will check out your site.
thanks man
