Hello everyone... I’m new the forum and just bought a 964 engine from LA_DIS with 75K mile on it. I bought the engine back in February of 2012. I put the engine on the engine stand tell September or so. For the past few months I've focused on body work and paint. I’m at the point of installing the engine. I started with a compression test and the engine is hard to turn over. Is there something I should do to condition the engine? This is the first HIGH compression I've worked with could this be the reason for hard turn?? I know the LA_DIS has a good reputation with you guys and most Porsche folks, so before I panic what should I check or do. ?

Take the plugs out and see if it's still high-effort?

Rotate the engine so that one set of cylinders points up; add a teaspoon of motor oil to each and roll the engine over. Repeat for other side. Still high-effort?

They have a **** reputation with me and many others .
They screwed me over and then lied and lied and lied .
They had a person on their team sign up for an account on this site
and that person was found out .

Hi Jebarco Hairston, engine looks very clean - is that your work or did you buy it like that?

I see that you've gone for the single top pulley, backdated oil lines and power steering blockoff - I presume that you are transplanting the engine into an older car???

I went with instant-gs conversion kit for the 964. Steve over there is the greatest..

Thanks everyone ,, This weekend I plan on removing the plugs, add some oil to the cylinders and trying to rotate the engine. Wish me luck!!!

c didy

yeah. definitely do it with plugs out, at least one from each cylinder.

He has his lovers and his haters same as LA Dismantlers!

While your engine is out of the car you may want to modify the bracket for the air conditioning (presuming you are not planning on running it). It's a really simple mod that cleans up the engine bay nicely, I'm pretty sure Timmins recommends it or sells them already modified. Couple of pics of mine here:

I see a G50 lurking behind your engine so I presume you're transplanting it into an '87 - '89 car. Lots of good info on the website above for this if you have problems or want to see how others have done it.

Im using a rebuild 915 transmission. This engine is going in a 75. I didnt get a chance to work on the engine this weekend because of work,, stay tuned.. @Alex ,, I do see a lot of posts on here for conversion,, gold mine of information,, thanks everyone..

Update:: I send a email to LADIS friday about the issue ,, and they where prompt on calling me back (called back 9pst ). So Im hoping i can get to the engine in the next day or so we can see what the issue is.

Update:: So I removed the plugs and added oil ,,nothing. I removed the sachs clutch / pressure plate and walla the engine turns. So the issue was the bolts that hold the pressure plate to the 915 /964 conversion flywheel was going threw and up against the engine. I added some lock washers and torque to specs.. Thanks Todd from LADIS for calling me back and calling me back at the doctors offices. I also purchased the high torque starter and should be installing the transmission and starter this evening.

I feel like a idiot.. No ring gear,, of course it would do that. Can someone tell me what ring gear I need to order for my 964 /915 conversion???

Hey don't beat yourself up ..it happens to the best of them..well maybe smack yourself once or twice on second thought!
You should be able to use most any 915 starter ring gear the one that originally came with the car will even fit and do the job I believe the diameter of your clutch and flywheel to be 225mm so you should be ok, Bert
