202 EFI engine

[zohpm]

On the weekend I bought a VK 202 EFI engine with 5spd and all the stuff needed to whack it into my VH. I was just surfing through another Holden info site and realised that it seems the EFI engine I just bought used to be carburetted. The engine I bought starts with VL.... and according to this site that means it was a carby version.

So I guess my question is, where there any internal differences between the carby and EFI versions? Anything that would make it not run as well as it should seeming it used to be a carby engine?

Thanks,
Matt

I think the only internal differences was a slightly better flowing head and a slightly different cam.

I'll go check the donk in PEAKN6 to see wat the engine number starts with...I'll also check the spare EFI block in the shed....just incase they had both numbers.

Ok well the engine numbers on both our EFI blocks start with VL......so u might be ok. Oldholden might have them around the wrong way......I'll go back outside to check the engine number on our black carby donk.

The number on our black carby motor starts with VL as well. So I'm thinkin that most of the carby and EFI motors started wth VL, and if VK is even an option, maybe there was a few. It's possible that originally our EFI donks were carby's.....but I doubt it. I think u should be right....I'd say ur's is a proper EFI, I rekon the info on oldholden would be a bit out.

We got a blue 173 and a blue 202 in the shed, but they're a different prefix again.

I'm sure someone else would be able to set us straight.

BTW....the manuals behind the EFI motors go alright! We did the conversion in PEAKN6(VH) a few months back......was easy as....the biggest headache was putting the new fuel lines in...it's not hard, just a bit annoying laying under a car getting them in right...altho if ya got a pit or a hoist it would be easy as!

Thanks for your efforts. I was told that the engine was out of a VK Calais and does appear to be (or atleast the EFI setup is) because the cruise control setup is on top of the engine.

Another reason I thought it might have been a carby originally is because of the 5spd box. To my knowledge 5spd boxes only came on carby versions and the EFI engine's torque killed them.

According the oldholden the prefixes for your blue 173 and 202 would be VD *snicker*, and VL respectively.

the EFI only had an auto trannie. chances are that if it was out of a calais (and it was an original motor) it would be EFI not carb. i beleive all the 6's in the calais were EFI? (correct me if im wrong) hope this helps.

Yeah I found out that VK Calais 6cyl where EFI and auto only. I guess that's why I'm kinda sceptical as this one came with a 5spd. Figured someone might have grabbed an EFI setup from a Calais and whacked it on their carby motor. And on the subject of the engine being an original Calais EFI, all I got is the word from the guy who sold it too me.

Guess I should just shut up and get it in my VH.

If ya suss out our site Home of the KERR BROTHERS! we have a section on the EFI conversion....hasn't got much info, but might help out.

[zohpm]

Yeah thanks I'll check it out.. I bought a VK workshop manual today so I have some info on paper. Oldholden's Holdenpaedia has some useful info too.

Had a closer look at my engine today and looks like its was a blue engine that's been repainted black. Any of your black engine blue underneath?

[DANNY8]

Nah haven't noticed anything blue-ish. We're pulling the EFI motor out of PEAKN6 2morrow coz we've got a new one to go in (blue 6 which we're putting the injected gear on, suss out '83 VH commy wagz' thread in the members rides section), so I'll take a closer look then.

Sounds like a blue engine that someone has painted black. You usually see this with red engines that people paint blue or black, so that it looks like the original engine for rego etc.

There is no real difference between the blue and black motors. And there is no reason why the EFI setup on a carby engine wouldn't work.

As u said, the difference is slightly better head flow, a different cam, and someone told me once it was a slightly better balanced crank?

I run a blue bottom end, with an black EFI head with the EFI gear. The conversion is pretty straight forward, but there are somethings i might do differently if i was to do it again.
