You'll never get what you have put into it obviously, but I'd say its closer to an $8K motor, if that. It's a niche engine for a small market as for a few grand more, a buyer can get a 3.6.

If that is a 930-10 ROW then you have 204 hp stock....with SSI's that you show probably 215-220. The PMO's probably give it some snap with the stock cam....I'd put a different cam in there with the PMO's and you should be in the 240-250 range.
It will also save you a bundle considering what you have done already.
I love my 930-10 as it is a sturdy as the US model with the extra HP....especially if you upgrade to a Carrera cooler unit to keep the temps way down (safety factor with the high compression) and use a good high octane.
Drop some weight from the car and it's a very fun drive.

Yes. 9.8:1 compression. No lambda control. Across the six years.

Stock engine is 20+ HP higher than US engines if bone stock.

PMO's will provide some HP but a big benefit will be throttle response.

Cams are the missing component. However, I don't know if the ROW SC's had the same cams as the US cams.

I do think this engine will bring a pretty penny as is, given a pro top end rebuild.

I say start at $12k as it sits.

I said $12k but that is not looking at other viable options, such as the 3.6.

Changes the playing field.

'78 &'79 ROW were 8.5:1 compression just like the US model.

I say 7-8k plus the carbs.

Shut my mouth. Looks like 81 was the big change for ROW. Thanks.

I can't find where the OP stated a year or engine number.....if it's a later 9.8-1 204 HP model I think he should just develop that a bit and save a great deal of money.
Either way he'd have a nice motor to sell...but might be satisfied with the 230-250 HP he could get there.

He said he think it is 180-200hp. From that I take it to be a later small port us engine.

I can probably get $3500 for the carbs as they sit, as they are virtually brand new. Maybe the smart money is to do that, then sell the CiS engine for 7-8k.

Leave it alone until AFTER mexico!

LOL todge. :)

the 930-10 82-83 is a large port @ 204 HP with the stock crappy exhaust set up.

Yes, Mike appears to be contradicting himself. I made my post hoping he would correct me if I am wrong since he's the only one who knows. I would expect this engine around 230+/- with the carbs and early exhaust.

Matt.
Wayne's 911 rebuilding book gives some figures for a 3.0 w/ 9.8-1 comp, CIS, 964 cam, SSI's should yield up to 30-50 HP over stock.

He's already got the carb set up so I suspect much closer to the +50...250/254 hp.

I think I'd try this route prior to an engine swap.

Me too unless you're targeting a specific racing class or hp/wt ratio for competition purposes. Especially after having just spent $8K on it.

OP- just trying to clarify, the bottom end has 40k on it (which was done before you owned the car and is missing documentation) and the top end is fresh as of October 2014?

I would start at $13,500 and go from there- any good 3.6 engine plus swap parts will run you $17k plus starting-

How difficult is it to do a cam install? I see a lot of WHY I should, but not any how-to threads. I'm looking for a 20/21 or 964 profile right? I might as well install to get some bang for the buck yea?

Consider purchasing the 3.6 before selling the engine you currently have. The recent prices I've seen for 993 motors that do not need rebuilds are staggering. Your enthusiasm may wane.

Another thing to consider is gearing and lightness. I have a 2500-pound M491 with a close-ratio 915 5-speed and a '95 3.6. It flies. When I drive my father's stock 993, it feels more like my stock '87 than my M491.

I've been looking for this as well. I have not seen ONE thread on how to change out cams. Doesn't look terribly difficult but, again, no threads. A how to, would be nice.
