Was told 270hp was about the max out of a tdo4l.

Hi man.

Thats original what I thought as well.

I had one split on a weld at the back @Paulmblew one to bits as well.

Yes love a challenge, was surprised how different the 2 magnum 2 frames are. The green one was for a early Z motor the red one had a GSX 1100et motor .

The id marks on the cams don't help as Mr suzuki had more than one cast & then ground to spec of model, but some have stamps on the end usauly stamped by tuners re-grinding. You need to measure them realy. Seem to remember @fatblokeonbanditDid a little study of his own on them. There is a link some where to the temporary site with a spec sheet for the cams.

Yes it would but the flange will have to be cut of & repositioned to clear the front wheel anyway so the world my oyster, well turbo choice is.

On a mission from Hamamatsu lol Yes it's addictive, plan on a upgrade for the Harris build going to leave the Scratcher alone this next year as it is so much fun to ride.

Am running a tdo4l turbocharger of a suberu variety which makes 260hp on a 1216 b12 based engin. Question is what would be the best turbocharger to fit to say reach over 300hp, as the tdo4l is at its just about at its max, recommendations pleas.

Think it is a tial or a copy of a tial.

@Goo'Roothought my WG spring was 8psi turned out to be 15.9psi. You could cut a bit of the spring.

Had a look at you tube out of curiosity to see a busa engin been stripped down & indeed the dots go at the front. Just reassuring my self realy lol.

Well spotted, last one I built I put the dot at the back did over 100 miles with it like this untill @colinworth79pointed it out to me, whipped the top end of turnd the pistons round & all was good. Apparently the gudgen pins are slight of centre.

Split the crank cases this evening gears, dogs & crank look good, every thing looks alright apart from the black sludge in the bottom crank case. Got some busa pistons & rods of another site member Had a set of b12 barrels that I wanted to use as the sleeves are 1mm thicker than the 1127 sleeves. I dropped the barrels of for a re-bore at the local machine shop the other day. Got a call of the this morning to say they were ready. Also got a 2mm spacer plate in the post.

Got a gsxr 1100L motor of another site member a few months ago this is going to be the power plant for the Harris. Pressure washed all the crap of it, dried it of over night then started to strip it down. Plan is to fit hayabusa pistons, rods with a big valve flowed head, gsx 1100f cams & 2mm spacor plate.

How did you get on with this, any Intresting results to report.

Air mixture screws on carbs maybe.

Copied it of Lee's first one but I glued the logos in.

Not cheap but is top quality, got it of @Jay_111Lucky 7 Moto.

Don't worry about it, will be ok without it.

Fitted some b12 carb rubbers & carbs to the dummy motor then the simple plenum I had. It will need altering a bit but it doesn't look as bad as I thought it might. Going to run the boost pipe from the turbocharger under the side of the engine where a normal frame cradle would have been.

Can not remember which tubes are diffrant, but it is only the L shaped bit that is usual brazed onto the tube that needs altering. All it does is stop the oil from blasting straight up into the engine from the oil pressure relief valve, not difficult to modify.

Simple one works fine on my set up. But may be a better designed one would be even better.

After lots & lots of head scratching going to go with the blow through turbo. Engine is now positioned to the front of the frame this will give more room for the pelenium. Turbocharger will need re-positioning a bit so it don't hit the front wheel.

I have a blow through kit as well for a b12 I could modify to fit. Just liked the idea of fitting a draw through kit to this 1980 Harris might have a rethink.
