99 spec engine - how can you tell?

[dreamers]

Finally about to buy my first rx7. It\'s meant to have had a 99 spec engine replacement but there are no receipts etc. for the work.

Is there any obvious way of finding out by looking at it by the untrained eye? I am gonna buy the car anyway and budget for a rebuild but just wondering..

your help would be appreciated as always

I didnt think the actual engine was different, just the turbo pack.

Not sure how to identify though I\'m afraid.

I am not aware of any differences on the later engine, turbo pack was upgraded on the 99 spec cars I dont think anything else was, sounds to me like a bit of a sales ploy, if its in your budget and it ticks all the right boxes go for it but I would be a bit suspect on the engine seeing as they are as rare as hens teeth in the 1st place, maybe he meant the engine was re-built then???

Out of intrest is it just the Loom, Sensors and Ecu that are Diffrent on the 99 spec engine?

i think but im not sure that the 99 speck had a black box instead of the rats nest under the uim.

The rats nest is the sequential turbo operation, so i would have thought that would still be there unless its been converted to Non-seq.

I read somewhere that the rats nest was integrated into a black box moulding too.

Ok, has anyone got a Pic?

Simple solution, ring Andrew at Jimmys, he has a Spirit R. He will be able to tell you.

Called him - no real way of knowing unless opening up. I will take it up to see him when i have it.

Thanks for your responses all

Looking at it (i may be wrong) but it looks like it has all the 93 ancillaries, it may be a 99 Block though???
