3.0 and 3.3 turbo crossover

Hi all, I recently blew my 3.3 turbo and was quoted 8k for rebuild, I was offered a early 3.0 for a decent price and have bought it. the 3.0 had a lot of money spent so thought it was worth it. It has SC cams a larger turbo and a 3.3 turbo fuel head, it has a few bits missing so i have decided to make one good engine from the 2. Firstly the 3.0 has a different distributer and was wondering if this can be replaced with 3.3 the reason i ask is I am changing engine loom and the 3.3 distributor has a wire coming off which goes to the spark box, the 3.0 doesn't.

Any help would be much appreciated

If you are changing the whole harness, I think you have to use the 3.3 distributor if my memory serves me right. What broke on your 3.3 motor? If the pistons/cyls are ok would you consider using those on the 3.0 motor? Not quite sure about fitment though..

Good point never thought of that, although this would mean more work than anticipated, would this be a worthwile?.

There is a fairly rare SC engine with the 3.0L short block and 3.3L heads. Ends up as 3.14L
Should be able to do the same thing here if desired.

Thing to remember is youre running a 6 bolt flywheel and 2.7 crank
To put the 3.3 P/Cs on you need to re bush your small end of the rods to fit the smaller wristpins of the 3.3
You have to change the whole intake if you want to use the intercooler
The distributor runs clockwise and the 76 930 used an 8 pin CD box, I dont know if it was changed in 77, its been a long time since I built a 77 930

Dizzy turn clockwise on 3.0, 3.3 turns counter clockwise, so no you can't use it

What means "blew my 3.3 turbo"? When you are around a bunch of guys with turbos, all of our engines are "blown" so the description needs to be a bit more specific.

The Porsche engineers probably considered your exact situation and therefore made it as difficult as possible for you to do what you want to do. If you mix the 3.3 turbo pieces onto the early 3.0 (really a bored-out 2.7), you will have a classic Franken-stroker. Electrics, distributor rotation, rods, crank - all of these pieces will cause you headaches as noted above.

I would sell the 3.0 with your parts on it to make it a complete engine and then find a '91-'94 965 engine. It would wake up your car and keep it more "stockish".

Good luck,

Mark

Ok ty for all the replies, I still intend to use the 3.3 wiring loom, I have the spark box so all is good that end, I am concerned with the green wire going to the 3.3 distributor, as the 3.0 does not use this will everything still be ok without using the green wire?

Regards

Plan B; I plan to use the 3.0 bottom end which was rebuilt with the addition of sc cams, I will remove the fuel head which is a 3.3 and replace with my 3.3 which I know is excellent, as I have already mentioned I will replace the 3.0 wiring loom with my 3.3 as everything matches, just need to know if the distributor will work ok as there is no green wire coming from it and will my fuel head work ok with the sc cams or will work need to be done there.

Thanks in advance

What is 930/# on your case? Is this a SC 3.0 or a Turbo 3.0? If it's turbo 3.0 motor the dizzy is #0237301001 or did someone change the gear on that dizzy. I think a 004 is a SC dizzy.

Thats one reason some use the RSR type 12 lead distributer ( Andial used it often as other 12 lead choices were not what they are today ) in the 3.0 turbo high HP ( old school) motors they built in the past, in case you wanted to go retro. Probably less problems and expence just to go to a later motor for the grunt you are seeking.

Just a thought, sell off the 3.0, part the 3.3 but keep the distributor. Then find a 91 or 92 C2 Turbo motor and swap it in but use your old distributor.

Or, sell the 3.0 and build up a proper 3.3 /3.4.

If you ever decide to sell you will have a very limited number of buyers that will be interested in a back dated 3.0T.

930's might just turn out to be the next long hood 911S and bump in value when the economy turns. If you go to Frankenstein it will kill you value potential.

Seems like a plan, unfortunately I do not have the funds, I have to make the 3.0 work for me, The two engines are comparable I have the dyno for the 3.0 and it shows peak at 347bhp. I just need to sort out the distributor issue and I am all good, much appreciate the advise.

started swapping bits today, took out both distributors noticed on the 3.0 it has a plug socket for the green wire, before i removed i cranked both engines and the distributors both rotated the same way. So can i put the 3.3 in instead, also noticed the 3.3 had 2 vacum hoses coming of it but the 3.0 has only 1.
