time to get on to the 72 fixed up , the engine does not turn over and most likley a dropped valve. It is a 1.7 as per year running carbs ...
so do i bother rebuilding the thing or should i just by a replacement from the states for a plug and play. note i bring in 911 parts via sea freight so shipping no issue

you don't have a good shop in NZ to do a full rebuild?

I think many times a plug and play engine is a crap shoot. many have engines that have been - quote - "rebuilt" - but they don't have all the details on what level of rebuild was actually done.

that said, you could get a freshly rebuilt engine from

mcmark -- http://www.originalcustoms.com/
or
raby -- http://www.aircooledtechnology.com/
or
others

and would be fine but you would need a good budget.

Is there anything else i need to do for the conversion. I was told at a show that the cams and heads are different between the 1700 and the 1800 is this true,http://www.rctophobby.com/fr/rc-helicopteres/achete-par-marque/esky.html, and that the crankshaft is the same.

what is your budget?

what would you guy charge to rebuild your 1.7?

do you have a particular horsepower requirement? thus the desire for a worked 2.0.

do you plan to run carbs or fuel injection?

lets see some pics of the car : )

The heads are different. The valve sizes in the 1.8 heads are larger, and the register where the cylinder fits in is different.

The cam should be the same. The crank is the same, the rods are effectively the same (different in detail, but they fit the same way) and the whole bottom end is either identical or is at least interchangeable.

The pistons and cylinders are different between the 1.7 and the 1.8, as well as the heads.

Can't answer anything seriously until we know budget, and some idea of performance goals.

Budget 5-7 k to get the car back on the road

I'm planning on selling a freshly built 2.0L with modified 1.7L heads, with less than 1 hour run time on it.

The engine is complete with all the tin (powder-coated), flywheel, alternator and ignition system all in place. It does not include intake manifolds, carburetors or an exhaust system. $2,300. USD (plus shipping costs).

If this sounds like something you might be interested in, PM me your email address. I can provide you with the build sheet/specs and pix ...
