The crank and rods look ok? I hope.....

so far so good. the crank is packaged up and will be headed to the great state of texas today for some armondo magic...

Huh, I wonder if the bottom end was ever done, or just along the line somewhere it got a top end with those abortion cylinders.

Those main bearings look pretty rough. When I did my engine at 111K miles, my old bearings looked pretty much exactly like the new ones I put in.

The #1 main bearing looks a bit grim indeed

Did you guys measure the crank at all before shipping it out? I hope CCR takes good care of you & turns it around in a timely fashion as they say. You gonna cross drill it?

I did not, but I'm confident it was measured. bob, the owner of RMG has CCR's attention on this & all his projects when it comes to armondo. he helped with getting one turned quickly when I did my spec motor a few years ago. although, armondo was a mere 15 miles away then.

so, 1st gut punch was experienced today. there's has been very little good news as this motor has come down, but this by far is the worst news yet... after gathering case dimension info for the cylinder bore seat we've found that they have in fact been bored out to 105mm:(:(. this greatly limits my P&C choices to say the least as is. there are calls being made to a couple Porsche exclusive machinists to see what shimming could be done to bring them back to the 103mm to accept the standard 3.o/3.2 P&C packages. one of the cylinders, #1 I believe already has some sleeve shim in place to about the top 1/3 of the bore seat = about 1/2". interesting that it was not the leaking cylinder that was cracked for those of you following along.

ive spoke to don at ebs that has a nickies big bore cylinder set that should snug right up to the 105mm case seats. to be accompanied by a couple of JE piston sets ranging in CR from 9.5 to 10.5/1. obviously the 10.5-1 ratio is way too high for pump gas for a street hot rod so I'm looking closely at the lower set at 9.5. the big bore set described is more expensive than the standard mahle fare, even in euro form. but, I'm suspecting the case shimming would make the BB set seam cheap...

1st gut punch, and a photo moratorium has been implemented until further notice. "notice" being when a solution/plan is determined. appreciate dan letting me get a drink ir 3 into me before I was to share today's bad news in thread. I was so sick over this I could not eat all day, and cried a lil during my customary lunch time couch nap...

couple things--

*if,, iiiir WHEN I get thru this the suspension work & IROC bumpers will have to wait.

*when I'm reving a 3.4L bigbore motor will the shinny, sweet, one of the "checked boxes" SSI 1.5" HE be inadequate? :mad:

I'm a glass half empty guy on most life matters, but ive got a great team on this unfolding disaster and I'm staying in a half fool state of mind. I just keep imagining how fun this car will be as it's developed and ultimately driven, fast.

From the looks of the crank the engine was grinding it's own bits for a while. Good luck man.

10.5 is ok for pump gas as long as you twin plug it. Not trying to spend more money for you. Just saying that 10.5 is capable of being supported by pump gas. It's typically the compression limit for 93 octane. Like Walt said, twin plugging is fairly cheap if you forego the distributor and use the old Electromotive HPV coil board setup. Works good despite not maintaining that original or vintage distributor look. I just hope your heads check out OK and you don't have to do much of anything with them.

Damn dude. Might be worth considering a replacement case that will allow you to use standard size spigot cylinders? Because this case right now is painting you into a corner of using machine-in cylinders which are big money as you know. Not to mention your main bearings looked pretty grim. So you may find that the case is begging for a line bore of the mains. I know main bearing misalignment is less prevalent on the aluminum cases. But given what you've found so far in this engine? Wouldn't surprise me one bit to find it's an issue. Just food for thought and not trying to be a Debbie Downer. Better to find out now instead of later.

So if you do a cost comparo, it may be cheaper for a replacement case and good used cylinders. If you can source a set of decent Carrera KS cylinders on the cheap, have them re-plated by EBS for either 95mm or 98mm pistons. Boring and re-plating isn't a whole lot more expensive for 98mm vs. just stripping and re-plating for 95mm. Should be just under $200 to do 98mm instead of 95mm. And 95mm vs. 98mm pistons is a non-issue in terms of cost difference.

Do you need heat and that's why you're planning on using the pretty SSIs? If no heat needed, I say don't bother with the SSI. I've got a set of 1-5/8" George's headers that I got for really cheap and I can pass that bargain on to you. They're a little rusty but still solid. Just give your local media blasting buddy a case or two of beer and then you can paint them yourself with some VHT or whatever? Get a set of the extension pipes from Marty at MSDS for $98 list (I recall he gives Pelican members something like a 10 or 15 percent discount) or find a set of used ones cheaper.

Keep CoryM in mind for your IROC stuff in the future, yes?

thanks for the time & consideration KT with some thoughtful suggestions.

not interested in twin plugging. my spec car ran on pump gas from the chevron station up the block I toted up in cans as to not have to pay track fuel costs.. I'm sure you are aware of the motor requirements in the class as you were very helpful with that build. in fact, as I recall you have a team shirt? ;) that being said the euro CIS P/C and stock cams in that motor worked with a dizzy recurve, so I suspect the 9.5-1 will work single plug.

We're having the case looked into, over & again before it goes back together. but, if I chuck the case and look to start over a new plan could be in order. all ive got is some used heads, a crank, rods a big runner CIS system, a brand new on engine oil cooler, and those sweet SSIs..;) before I go that route I will scrap this motor with a part out and look for a decent 3.2 I can plug in. I missed a local motor in the classifieds that sold last week that seems cheap about now....

the SSIs, the IROC body work were tongue in both cheeks..... I'm so far from that it sickens me some. I will be driving the car with the shotty OE bumpers for the foreseeable future.... insult to injury? still owe the great state of CA sales tax on the purchase.... screw me & then screw me harder...

gunna go meet dandy at the shop to scrape sealer off my question mark of a case this sat while he fiddles with his truck.. I'm looking forward, and possibly for a 3.2..

How about look for a standard 3.0 case, and sell your enlarged spigot case to someone who wants to build a big bore?

with the info shared here my existing case will not be a hot commodity. if I can find a case for the right price I would consider that. I am actively surveying the classifieds for such an option. do you or any other members of the Midwest mafia have any cases available?

So now I confused. I thought this was a hot street build. This is going to be another SP911 racer? Sorry for the dumb question and being out of the loop. I wasn't aware you dumped the 996TT and came back to the air cooled clubhouse

Souk,

Do you remember what the scoop is on that "spare" 3.0 case Chris has on the shelf? I vaguely recall it may have been machined for nonSTD bearings, which is of course a no-go due to the redickerous cost of over/undersize bearings

I do not know the status of the case, Kevin.

Toby, my thought with your bored out case is that it gets checked, and if the only thing non-standard is the spigot bore you could sell it. You then replace it with a standard case so you can go back to 95 mm p/c's.

I have two 3.0 cases, but one is a motormeister core that I have not opened up. So it's a major unknown. The other case is one I bought to replace the motormeister case which has some damage that can be repaired by a good TIG welder. Timing is bad or I might have something for you.

I thought I saw a 3.0 case in the classified not too long ago.

hot street motor. just referencing the spec motor for compression v. octane offered out here. the smog exempt status of the 75 tub of the new car is what's appealing to me. the goal is a spec911 like car for the street.....

the turbo only lasted 10 months. did not care for it one bit. way to insulated of a driving experience, and it had to be driven stupid fast to really make it fun. stupid fast for the street anyway, and I had no plan to track it. was a good experience in that it made it very clear ive got older aircooled desires ingrained deeply..

You can go up to 10.3:1 on pump gas. That's what the Euro 3.2 engines are rated at. But if you go aftermarket pistons, make sure to get teh wedge dome style that allows the single spark plug to avoid being shrouded by piston shape (like typical symmetric JE pistons with valve reliefs)

But if you're going with carbs i'd be cautious and not go that high of a compression ratio on single plug. what cams are you going to use in this eventually? Carbs + hotter cams puts you in a different style of piston and here we go again with what comp ratio works with your cams and pistons. Vicious cycle of decisions.......

Welcome back to the glorified lawnmower engine club!

I may have to take the motor from my mower for install into my car if this keeps up....

so, after the week spiraled in a hellish nightmare of bad news I believe we are back on track. put out the word to some old PRC friends that are shop affiliated, owners or retired Porsche techs doing things on the side in their retirement. the beating of the bushes was fruitful in that I found a 3.oL case that I will be collecting later this week at a very good price. have one with around 110k miles that according to my savior is in great shape. compared to the MM turd I found buried in my motor compartment this is very promising.

still moving forward with things as the shipping & receiving portion of the build is underway. crank found it's way to texas and CCR will hopefully have it headed back early next week after pulling plugs to clean, cross drill and hopefully only needing a polishing. as bad as the bearings looked the crank as I'm being told did not look too bad. it looked good to me of course.

before the case was sourced I spent sometime Saturday at the shop hanging with dandy while he serviced his truck I scraped glue from the MM case. great exercise in patience, but was too slow to make it my day job according to dan. time well spent none the less... some of my work

with the new case headed my way more of this is in my future if not cleaned already. for what I'm getting it at I don't care. as slow as I was at it I did not gouge or scare the case by petting the bunny too hard. my work even passed dandy's high standards...

rod were dropped at ted of german precision front porch, the heads were packed and headed off tomorrow as ted hasn't the time. he will be allowing me to use his blast cabinet for tin & such in the coming weeks. I have also taken KTL up on a cam tower as one of the two that came off is not fit for reuse. thanks KT!

this will be costing me waaay more than expected, but in the end I will have a new motor that I should keep until a dirt nap comes my way. it's a good feeling to start the plan to build things up, instead of jus bad news tearing things down.

I know this is not the right forum, and will be posting in the classifieds, but I'm on the hunt for a sound 3.2 oil pump. if anybody here has one id be happy to discuss via PM. thanks in advance, and on we go!!

As Souk suggested, I have an extra 3.0 case if needed.

Toby,

964 pumps can also be had for a good price. A bit bigger pump (much bigger scavenge side) like the 930 pump and drops right in for the most part with just some minor massaging of the case webs.

Just need to make sure to use the little spacer shim for the vertical pressure relief valve in the engine case per the parts diagram. All told it's a very nice upgrade for no additional cost over a 3.2 pump and MUCH cheaper than a 930 or GT3 megabuck pump. Blackbyrd always seems to have a handful of these 964 pumps in his collection of used offerings for a very reasonable price.

not a fan of blackbird. his reputation for delayed shipping is not something I want to get into around the holidays....

im trying to contact glenn yee MS to see about their refurb unit opportunity as suggested via PM last night by a member here.

Understood. Good call by the way going with the 3.2 or later pump. Seems to be some occasional occurrences of the SC and older pumps are showing some failure of the separate screen/venturi plate. I had that happen to me. Whereas the pumps with the integrated venturi & screen seem to be bulletproof in that regard.
