LT5 swap into 89MY L98?

[widebodyzr-1]

whats required to make work? i have engine w/harness and will be converting my ZF to longer shaft.

can my existing electronics (dash, CCM) be made to work?

any response appreciated. thanks.

btw - long ago i had the ZR-1 wide body installed; me and Bill B. *might* be the only 2 to have done this. maybe not...

There is a gentleman named Leon who has done it to 2 narrow body corvettes (1992 coupe and 1995 convertible)

You need to modify the engine harness. I can pass along his info if you are interested

His next project is a 1993 ruby convertible LT5

appreciate the response, thanks. yes, please PM me the contact info.

what would be different between Leon's conversions and myself is that i have the older style dash/wiring harness. would my harness require modification as well? i thought i saw someplace recently where an actual 89 ZR-1 prototype dash was for sale. i'd consider installing that, if i could find such a piece.

What about my CCM? anybody have any thoughts?

An 89 prototype dash would be very pricey. (most prototype stuff is)

He is a class guy and can custom make your wiring harness (like he did for 2 others)

thanks a bunch; i'll reach out to him.

looking at this ECM schematic, it's not clear to me how the CCM comes into play:



need to keep digging...

Your 89 does not have a CCM

i must be confusing acronyms then...

CCM is the body computer.. it controls the dash ( basically)

ok, so really basic question.

is the CCM located under under the passenger dash on the ZR-1? where the non-ZR-1 vettes have the ECM?

thanks.

NO..

Now excluding prototypes etc for a moment and concentrate on production only..

84-89 Corvettes had the ECM behind the 'bread loaf' on the passenger side of the dash. They also did not have a separate CCM, all the fuel calculations etc were handled by the LCD Cluster itself

90-96 (ALL: non-ZR-1 and ZR-1 90-95) had an ECM and a CCM.
the ECM is located above the battery. the CCM is buried behind the Radio in the dash.. the CCM controlled the LCD on the cluster. so any function of that LCD on 90-96 was handled by the ECM.

If you install a LT5 (best to go with production parts) I would suggest a 1990 or 1991. you would need to try to interface the engine harness with the 89 wiring going into the car at the driver-side bulkhead and passenger side pass-thru. You will also need to add the second fuel pump and wiring for the key if you choose to have full power as an option
