My plan is to turn it into a coupe and bring it back to a collectible Porsche

google "robbby" "jbweld" "blue silicone" "random blue paint" and brace yerself for a hugeheapinghelpofawesome...



welcome, and good luck!

making a lot of progress.....

been looking at rotisseries. and need to find some more storage space.....

[911tracker85]

cousin dropped by and helped me get the cam nuts off. and since I have pulled the PP/flywheel, had to improvise on a crank lock. per Wayne's book, backed off all the rocker arms too.

just getting started on the TB/WP on my Bro's 87 944S, and planning a full suspension upgrade on the 951, so work on the 930 will be pushed to the background for a bit.

What year 930 gearbox did you get? You'll need a short 76 77 gearbox to fit into a 911.

Others have attempted the same

930 trans in 911 mid year.

[911tracker85]

it is an 86, and yes I know it will take some work. have a good welder/body man. and working with Steve Wiener, Rennsport Systems to rebuild, regear, LSD and help figure out the fitment.

will get the engine / tranny rebuilds done and verify fitment before the paint.

PS. thanks for that link. think I had seen it and had meant to save that link for reference.

Awesome,looking good Bob. I think your engine lid would look good like you mentioned by cutting it out and using mesh screen. Easy way also to fix it. Lot of work and time to straighten out all those louvers and in the end you'll probably cut it out anyway. If the sun roof is something that you really want to do,go for it. Because after you'll be saying to yourself,shiyt,I should have removed the sun roof. I did that with my roll bars,thought about doing it and let people convince me i don't need them.I was already in there,had all the tools out and now I regret not welding front bars. If your handy with a welder you can easily build your own rotisserie. I can show you how I built mine with adjustment on it to work with any car.

[911tracker85]

well.... I am buying a good DP935 tail. I really like the one I have, looks right and different than the average 930.

when I get the new one, considering having someone make a mold out of it to repair my old one for someone else to use.

so far I have not learned to weld, think I will need to do that. others have noted how they built rotisseries from HF engine stands, etc. it will be a while before I make the decision to buy the rotisserie, but have decided I will. for $800 not sure taking the time and effort to build one is worth what I would save. can sell when done if I dont think I'll be doing something like THIS project again. getting too old....

update to the project.

well I kNOW the WSM assumes you already know a lot. am finding a few missed details in Wayne's book.

after removing the cam nuts, say to pull the cam sprockets, etc. and THEN remove the tensioners.

after thinking a bit, I believe the missing step is compress the tensioner and insert retaining pins. now you can get the can sprockets off as the chains are loose.

move along.....

[911tracker85]

while waiting for some parts for the 944S, went back to work on the 930.

once I get the case stripped down to just the crank and rods, shipping to Steve Weiner at Rennsport Systems to do the bottom end. along with the heads.

still has original divlar studs so they all come off for replacement.

[911tracker85]

thanks to KYCARGUY, I have a good DP/Kremer tail. will make a mold from it to ultimately repair the other one and sell someday.

930 work continues between work on the 944S, almost done, and the suspension for the 951 DE car before the first event.

[911tracker85]

during short breaks on the 944S project waiting for parts, got one of the heads off.

but now starting the suspension upgrade on the 951 so the 930 will have to wait a bit.

[911tracker85]

well.... getting back to work on this project.

got all the heads off the cam towers.

yesterday, got all the cyl/pistons/rods and head studs removed. as this engine was fully rebuilt in 1990, all came off easily.

need to check the ring clearance to see if it is likely I can reuse the cyl/pistons. they all came out looking good, but the feeler gauge will tell......

need to pack this stuff all up and ship to Steve Weiner for full refresh.

[911tracker85]

more progress getting the parts ready to pack up. everything came apart pretty easy, including the studs. engine had been rebuilt in 1990.

bolted the heads to a board.

I hope I can reuse the pistons/cyl, but will let Steve verify. measured the compression ring clearance. think only two are near the limit.

[911tracker85]

well time for an update.

unfortunately for this project, I have mostly been working on the other cars.

but in between continued the tear down.

got the windshield pulled and the tub almost stripped. almost have the wiring harnesses pulled.

just sent Timmy2 (Dennis) an email it is time for us to link up on having him build a full set of wiring harnesses.

after checking the ring clearance, found two at/above the wear limit on the compression ring. fortunately a local Porsche master mechanic/friend has a set of P&Cs from a 3.4 upgrade project I am buying. only 24k miles on them and all in exec shape.

also got a set of front, raise spindle stuts and F/R bilstein revalved shocks from the same friend.

I am retiring end of Sept and have pulled back to part time until then. so anticipating more personal time to do more work on this project.

hope to be posting updates with progress.

[911tracker85]

in between other projects, DE track events, and the endless 'honey do' list, have been getting in some work on the 930.

been disassembling the suspension parts, cleaning, etc. should be getting a box of parts in the next day or two.

finally about to ship off the case to Steve Weiner at Rennsport systems to fully rebuild.

but for today, off to the shop to finish a AC compressor swap on the 944S and get the 951 loaded in the trailer to go to 944fest at Nelson Ledges 8/3-5.

will post more when I have the pics of the work.

[911tracker85]

OK, here are a few pics.

going through a lot of parts I had already bought before I decided on a full restore.

then pics of some of the suspension parts I cleaned, blasted, and painted. going to have the front A arms done in PC black.

just finished replacing the AC compressor in the 944S. and about to start preping the 928 for a paint job.

off to the 944Fest at Nelson Ledges in two weeks in the 951.

and planning on getting into more work on the 930.

next up is cleaning/painting the oil tank.



the two P&Cs are the old worn ones from the car. I blasted the outside and painted. I got a new full set of P&C, well slightly used 26k miles. need to epoxy a bottom on the cyl for beer mugs. seal the little oil holes in the pistons and they may make a good double-shot glass.







new turbo tie rods for the SC rack. and wheel bearings.


full set of fuel lines from Len Cummings, plastic tunnel lines not shown. along with the new fuel pumps, filter, and accumulator.

[pkabush]

Nice. Your cleaned and painted parts look great.
I’m going to be embarking on a similar project soon. I just put down a deposit on a 77 tub.
I just happen to have a spare 930 motor and trans. ;-)

[911tracker85]

I still need a 930 trans. otherwise, I think I have most of the stuff. sending out the case to Rennsport systems for rebuild, then the heads. then need the rebuild kit/gaskets, etc. etc.

still have not decided on color.

good luck on your build. will look for your thread.

[pkabush]

Thanks.
There was one in f/s section awhile ago. I don’t recall the price but it seemed to be a good deal. I think it was rebuilt and as far as I know he didn’t sell it. It wasn’t a early model (short b/h) but those are getting pretty hard to find without giving up a kidney or your first born. IIRC it was at a shop that was capable of shortening it.

[911tracker85]

time for some updates.

first is to say I sold my 85 911 that I had owned for 27 yrs recently, along with the 87 944S. too many cars sucking up my time and now that I am retired this 930 is going to start eating money. I would never have sold that 911, my first P car, if I was not building this 930.

actually I have been working on parts. some cleaning, bead blasting, etc. in between work on other cars and the challenges of life.



getting ready to ship the case and heads to Steve Weiner at Rennsport Systems now that I have the funds. already have the heads bolted to a board. will also be sending my P&Cs, got a used set from a local Porsche master mechanic that only had 26k miles. he had done a 3.4 upgrade. my P&Cs were in bad shape. also rods, rocker arms, etc. for refurb and to allow Steve to balance the rods to the piston as much as reasonable.





had the A arms powder coated. installing new ER rubber bushings and new ball joints.





new ER sport rubber rear training arm bushings.



and a set of RSR raised spindle front struts with F/R revalved Bilsteins from the same guy as P&Cs. they could accommodate coil overs but not planning that. keeping torsion bars. toying with idea of using mild coils with a compatible set of torsion bars. but keep reading how this can make it harder to set up the suspension. we'll see, but definitely not planning full coil over.





new wheel bearings and races installed.


got a replacement pedal set. ironically the only place I have found rust on this car was the pedal cluster and floor area. I was going to refresh but just cannot get that pin out to disassemble.


new turbo tie rods on refinished steering rack.
