250 turbo engine into a 220 turbo

[Dave MGT]

Just a quick question to see if im right in saying a 1989 turbo s engine will go straight in a 1986 220 model. The engine will come complete with the turbo and clutch etc. and I will be getting another set of chip anyway.
Just wanted to check porsche didnt change engine mountings/brackets etc on later models...?

Thanks

Id want the ECU, and possibly the airflow meter too (Id Google for a list of which ECU went with which AFM and injectors - I dont have the list on this PC unfortunately).

By the way, what sort of price have you got an engine for, as Im looking myself?

It should slot straight in. As far as I am aware the differences are:

Turbo - bigger hot side
Different injectors
Different DME and KLR chip

I think the Turbo S also had a two piece crossover pipe to aid removal for things like clutch changes. Later DMEs also had a different chip receptacle on the motherboard with more or less chips. Can't remember which way around but they are not interchangeable. Probably worth checking that out.

I was looking at the one on ebay 65k £750

24 Pin Chips on early cars, later ones have 28, the early cars will run on the later units though, my 220 had a later DME (28 PIN UNIT)

Not saying the one you are looking at isn't genuine, but don't you just hate the fact that you go to buy a second-hand engine, and they are all low mileage, yet none of the cars in the scrap-yard they came out of ever are?

Nothing you can really do apart from try and look past the parafin reconditioning, and try and judge what sort of shape it really is in., Fortunately in general it is something I left behind when I started playing with German cars rather than old Vauxhalls (er, yeah, ok, some bits of them were probably German I know)...

 

[944 man]

Not a bad price if its a fit engine.

Re the comment above: the magic number apparently, is 75,000; with sub 69,999 being the ideal. That mileage was believable in 1995 (though seldom true even then); but its a joke now.

What used to get mme more was the 'require your engine in return, scam.

Id still be wanting any engine bought to be turnkey btw..

More or less a direct swap. 24 pin DME can be easily convert to 28 pin. Just get a correct program. I haven't notcied any difference on 220hp vs 250hp KLR proghrams. Injectors are the same on both engines.

I tried to buy the car that this engine came out.

The mileage is considered to be genuine but the car was totally rotten and it was a damaged repairable.

 

[944 man]

Pretty good provenance: buy the engine turnkey and youre away! If you decide not to go ahead OP, then Id appreciate a PM letting me know where the engine is.

After discussing this particular engine with the owner (and the previous owner), I ended up buying it - complete with turbo still fitted , power steering pump, air con compressor , alternator , fuel rail / injectors , bell housing / clutch still fitted and tdc sensors , wiring harness, water pipes, oil cooler and pipes.

I also bought a few other bits & pieces for my road worthy Turbo. Not entirely sure if I'll need the engine but I don't think I can go to far wrong having it sitting in the garage under wraps until the restoration project is up and on the road.

In relation to the mileage at 65k, I have the stamped up service book to 50k and the last 7 years MOTs stretching from 52k to 65k plus a bundle of other paperwork relating to work done which corroborates the mileage. I also have the clocks from the car and many pictures of the car (inc interior) prior to breaking. Of course, none of this guarantees the mileage is definitely 100% accurate but it does suggest that, if it isn't, a succession of owners have gone to some work to fiddle the mileage on a regular basis! This is unlikely.

I also have the bill of sale which makes interesting reading. Merlin Cambria sold it for £42493.79 in Oct '89 and Mr Morris traded in his 1 year old 911 SE in exchange and received £37100 as a trade in price!

So would you sell the engine then?

 

[simkin911]

If it turns out to be surplus to requirements then I would sell it in the future but I haven't bought it for resale purposes (if you know what I mean). Gives me the option to look out for a cheap turbo that needs a new engine ([]) !
