How do I know if esprit is HC?

Hello

I have searched the forum for an answer, and I have not come up with anything.

I own a 1986 lotus esprit, and was wondering if the engine is HC. The decals that I have seen on some cars that say HCI on the side have been removed by previous owners.

Post up your engine number, someone will be able to tell you i'm sure.

Mark , the second character on the engine number (stamped R/H rear of block above the starter) should either be an A (for HighComp) or P (HighComp/Air Conditioning)

Also the valve covers, inlet diffuser and carb plenum should all be bright red (like a Ferrari Testarossas)

I could be wrong here, but isn't the HC motor easily identified because it's got red cam carrier covers, plennum, etc...? While non HC motors are black?

My motor number starts LP and my engine bits are red. Does this mean I have and HC?

The HC turbo didn't preview until October '86 so its a pretty firm bet if the date code part on the engine number indicates a build before then, then its not a HC. There must be very few about since production of the Stephens cars followed on the next summer.

Clay, the Federal spec HC engines all were in fact HCI (fuel injected)

If yours is carburetted (as per a normal Federal 83 Turbo) it might be that someone has installed a HCI engine but retained the Carburettors.

The block number signifies its a HC block at least.

Well it is definitely a HCI!

The engine number is LP910860223028

I am pretty sure it was built in February of 1986.
