What a beast. I've bought a coupe, complete, but in a million bits. Currently tossing up what to do. Modify and update to improve or stick with original. I must say you're committment is impressive. I'm exploring the possibility of installing another bike motor. A current 600cc honda motor produces double the original horsepower and is actually more compact. The trick is how to convert to rear wheel drive?

this car is being done right good luck to you

Leo, your car is looking great.The engine bay didn't require much alteration at all. Are you going to keep the interior original? I hope it looks like a s600 coupe that goes like a scoulded cat.

Have a look at this motor. They make kits to convert Hayabusa motors to rear wheel drive car applications. The also make a v8 essentially using two hayabusa motors. Hartley Enterprises

The H2 is designed to provide a rugged durable platform for those that desire to put a Hayabusa engine in a car type application. It has a billet case and sump, flywheel for mounting a clutch and rear drive take off, 60 amp alternator, 4 stage dry sump and starter. Rear adapter plates are planned for popular gearboxes. The engine is estimated to have a fully dressed weight of 140lbs and can produce 175 to 250 hp NA; and much more in turbo form.

The H2 BUSA engine is offered as a kit or complete engine. The base kit utilizes the Hayabusa crankshaft by using a special adapter for mounting the flywheel. A Stoker kit is offered with bespoke 72mm stroke crankshaft, with larger bearing journals, H beam billet rods and related pieces to allow building a 1.6 liter engine.

See the price page for more details.






Considering the interest in buggies and auto-cross, the engine was designed with an enclosed belt drive for the alternator and oil pump. Using a single belt instead of two belts shortens the engine length by 20mm.

This picture shows the belt drive with the cover removed. The pulley drive for the oil pump and alternator can be seen. The large hole in the front cover is to allow air to circulate through the belt drive and out by the alternator aided by the alternator fan. The large hole is shrouded by the pulley's shoulder so it is effective at keeping out large debris.







The engine lower part of the case is machined from 6061-T6 solid aluminum. The primary design objectives were compact size, stiff and robust and optimize packaging for 4 wheel applications.













This view shows right side of the engine and the 4 lb flywheel (140mm clutch). The ancillaries are all placed under the intake side to aid in packaging. It also keeps them away from the heat of the exhaust and gives plenty of room for that extra large turbo which will one day find it's way to this engine.












Dyno testing proved durability and power. The engine tested is over-bored to 84mm (1.4 liter) but otherwise uses completely stock Hayabusa heads and cams. On this run it produced 195hp with a very flat torque curve, but more is available with modifications.

The engine is very smooth. The bit of vibration seen at the end of the video was due to the the engine hitting the 11,000 rpm rev. limit.

I was considering the same type of swap on my 65 LHD coupe. Looks great!

looking good Leo. got it back on the chassis yet?

mine is way behind shedule and so much still to do.

franckcrx

Congrats, it's a very nice work you are doing, i will keep on following ^^

Ooooooh yes, very good. That is one beautiful build. It must be nice to lay out every wire and hose just the way you want right from the start. Keep up the solid work!

Bozwell

6PK 1000 belt, adjustable altenator bracket and idle gear swapped for the grooved one for a simple belt arrangement. but the alt is very close to to the uprite.



and i'm actually making the complete exhaust system at the moment so i know where to weld the brackets to the chassis. chassis weighs a ton with all the extra metal iv'e added.

i'm very jealous on how far ahead you are though. (even though it isn't a race) iv'e got lots of thoughts on the exhaust system so if there is anything you wish to ask send me a PM

I notice from the photos you are running a standard steering column. Since you've gone over 45%of the original motor capacity according to the RTA guidelines you must install a collapseable steering column. Has your engineer advised differently?
You're headers are very close to the steering column and inner guard. Could there be an issue with engine rotation under load?

Regards,
Peter

bump...more please!

Fantastic project. Car looks great thus far. I just picked up poor condition and engineless 1965 S600 so this is great inspiration.

Hi,
can I ask were did you get the POLYURETHANE 75 A body mounts from? I live in Australia.
