930 pump is a good one. Shame they don't make it anymore and instead its been superseded by the 996 Turbo pump (not a bad pump either).

Good on you for taking apart your pump to inspect and re-sell to someone with visible proof of assurance that it's a good pump. Like you saw in my bearing shower thread, a thrashed pump could EASILY be passed off as being just fine. From an outward appearance my 964 pump that ingested bearing bits looked just fine. The pump spun smoothly with no indication of internal damage. No visible damage to the rotors when looking thru the ports and no debris in the pickup screen. But inside the scavenge side of the pump, the precision machining was wasted.

Thanks KTL.

So I got off the phone with Charles @ LN. Had a real nice talk on the phone. Wanted to confirm shipping my cylinders off. Talked about specs on the pistons and what to expect with the replating. Took all the info for my build to make the custom 10.5-1 FSR pistons for the build. Talked to me about his R&R rods for a bit too. I looked at them early on but the price difference between the Pauters and the R&R was a the breaking point. Apparently they are trying to make a set of the H beam rods for the later 996/GT3 crank engines but in the 993 stroke. They should be ~25G lighter then the I beam rods they make now at ~547G. Does anyone have any pros or cons on R&R as a performance rod? 522G sounds like a nice light rod. Ive heard good things but not alot like other popular rods. Henry S. seems to like them. Hoping he chimes in. Seems like R&R are a Carillo rods +quality at the pauter price. Would love to hear some advice from other guys who have used them. Kevin ... you remember what your Pauter rods weighted?

Good call on the FSR. I intended to get that too but screwed up and didn't make sure to specify that when I placed my order with Charlie.

522g is indeed a nice light rod. By comparison my Pauter rods weigh 576.5g to 576.9g. Just weighed them last week. They're standard 3.0L rods, not their lightweight ones (520g), nor their special ones set up to use 2 inch NASCAR/Buick rod bearings (512g). Their 993 rods are 545g. So the R&R rod is a light one for sure.

Yep, I figure they FSR is only ~$30 more a piston. The OEM 993 pistons are FSR and its an added bonus they are lighter. I cant afford to do a set of Carrillos and it seems in the recent history they have slipped a fair bit in quality control. These R&R H beam rods seem to be the cats meow. I was pretty set of Pauter but Charlie said he would match the price which was BIG. Im sure either way Im not going to be stressing either rod. Tried to search last night but didnt find much on whos used them and comments of the rods. I did ask if I would have to clearance for the 930 oil pump with the rods like the GT3 pump needs with the H beam Carrillos. He didnt have an answer. I guess once everything starts coming together well find out.

Hello All ... Bringing this thread to the front. Got back from sea a few days ago. Lots of goodies have showed up in the meantime. A shout out to Charles @ LN, David @ Marine Crank, and Henry @ Supertec for working with me while I was away. Thanks.

So Just waiting on the last few items and my case to get back from Henry from shufflepinning and I should be ready to start assembling it. I was suprised to find out the JE 10.5-1 pistons were heavier then the Mahle stock 993 pistons. Maybe I got a lighter weight group, idk. I was very happy with the R&R rods coming in @ 479g. The FSR pistons were 468g and 565g with the pins. The pins were lighter then the stock ones which was nice too.

I have a question about balancing then pistons and rods. Is it worth machining the new JE pistons to reduce the weight even more to get them lighter or just deal with the pistons being heavier then stock. I am going to have the whole assembly balanced with the crank and flywheel. I would have the weight taken out of the skirt ... Im not sure if this is a good idea or not. I have seen a few build where guys have machine the shirt similar to the mahle RSR pistons. Here are the customary pics. Thanks guys.http://forums.pelicanparts.com/uploa...1394211554.jpg

Here are some pics of the piston machining that Im talking about ... Looks like some take it out of the middle of the skirt and others take it out of the sides.

I still need to take the sharp edge from the valve reliefs. I am excited to get this together and find the actual CR too.

Those aren't a ton heavier than the original Mahle pistons. I would say if they're all consistently the same weight, then removing the material to lighten them isn't really necessary.

The pictures you've got of lightening isn't really targeting the skirt as much as its taken out of the crown. Here's some of the typical lightening locations JE targets.

Those R&R rods are really pretty. Good choice there. Wow are they light.

Thanks Kevin. I was talking about where they "mooned" the skirts. I see the machining to the crown underside now ... missed that the first time. The only scale I have is +/- a gram. Im looking for a 1/100th gram scale to see what they are. I made a quick chart in excel with all the weights. They are very close. All the pistons are 467g, the rods are 479g except two 477g specimens, and all the pins are 97g-100g. I think I can balance them very close with just matching the pins. Im very happy with the turnout.

Oops I didn't catch the mooning on the bottom edge of the skirt- duh me stoopid.

I feel like i'd leave the skirt alone. That FSR skirt is already pretty narrow. Pin boss is a big hunk of metal on the piston but doesn't seem like there's any room to lighten it w/out getting into the braces. So i'd look at the crown for lightening.

No worries Kevin. Its a toss up. Is it really worth the extra weight savings or getting into harmful territory? And how much more $$ is it worth to drop for something that in the big picture is not that much more useful. I cant lighten up the reciprocating mass any more then this. Just want a snappy engine. Not a race engine but just trying to get it as good as I can get it now while everything is apart.

I agree- piston weight pretty much is what it is. If you were really trying to cut the weight, you should have gotten a set of titanium rods. :D

It'll be pretty snappy. If you want to be really snappy, you need to get one of these ;)

Clutch - 5.5" 3 Plate Carbon (Pot-Type)

Well ... touche, lol. I did the best I could with the $$$. I was surprised when Charles told me the rods where in the 480g range. Orig we thought they might be in the 520ish range. Ill take what I got at this point. I am looking at the Wevo Steetlight package. Seems to be a very good package and complete compare to its peers and $$ range. I think that comes in at ~12-15 pounds complete including flywheel, clutch, and PP.

I think I have plateaued right before the slope .... :D

Well see I wasn't too far off base suggesting that clutch! I'll be honest that I have a Superlite hydraulic racing clutch on the shelf waiting to go in the racecar whenever I get around to it. We'll see how unruly that tiny little thing is!

I think the Streetlite setup is a nice piece. AP Racing makes fantastic stuff. I'm sure that clutch housing is bulletproof.

Yeah, I looked into the KEP clutch like you mention a while back. The price of this vs the CF and KEP kit was similar or more. I talked to Hayden about it and they seem to be working really well. A few larger 3.8-3.9 rally motors have stressed the PP but they have a larger beefier PP for 3.2 engines or larger. Seems like the Wevo/AP racing unit will be good investment. Im curious to see how the superlite works out for you ... I couldnt imagine using that unit in a street car, lol.
