PSI Performance 1155cc twin.

It began life as a 1085. The previous owner punched it to an 1155 refreshed the crank and sold it to me.
This guys shop was spotless and emmaculate. You could eat off his floor. He took care of his equipment.

So do I.


FULL PSI 1155cc twin engine is listed for $5k.
I have $11,300 into this engine (not counting carbs and pipes).
They sold for $7400 new.
I now have about $11,300 into it right now after buying 4 extra pistons and a new crank that Bruce snapped last summer (LONG story).
I listed it originally for $5000.
I have it for $4750 right now without the 4 new pistons I just bought.

This isn't a top end kit for a Cat bottom end. IT's a full PSI cast case and billet crank. NOT a cat bottom end.


Comes with:
Recoil and water pump assembly.
Full ignition and CDI, wireharness, ETC.
Huge powdercoated torque plate
2 sets of pipes. Custom secret SLP twins and "stock" psi twins. One set of PSI silencers made to fit either pipes.
Mikuni TM40 flatside carbs bored to 42mm
Turbotater ported (this engine RIPS) and runs right with the turbo'd dragons at 9-10 lbs boost.
Filters on the carbs with new prefilters...90° elbows to stand them up.

This engine will pull your arms off. It REALLY rips. Turbotater (Wayde Johnson) knows his stuff and REALLY woke this engine up last year. IT's NOT a PSI lemon. I've had GREAT luck with this engine and anything that kept me down was self-inflicted. This has been a GREAT engine.

It's just time for me to go into a new direction.

I guess I'll have to get out the vid cam and throw down some marks or drag races.....

OH........I have THIS vid from 2004.
It's a short rack race REV with a Crankshop full race 1000cc twin.

The porting and new clutching/pipes have been done SINCE this vid was taken.
I think we were both short on r's that day though.
Not a GREAT clip, but thanks to Spud for filming it.

Still for sale.

I have the twin to your engine in a ZX and the engine is going to be fore sale maybe. Just bought a 05 900 efi motor to replace it with and take it to attitude for a turbo if things work out. BUT have you looked into putting the efi system on the 1155 and then turboing that the bottom end i have been told is based on a cat will be making some calls to see. My motor has 40hrs on a fresh rebuild welded and balanced crank and do not want to give the motor away. Wil kep you posted if it is possible.

This engine is a Polaris based PSI built bottom end.
