Got so frustrated with 86' 951 (interior parts falling off, spindles/hub issues, oil leaks, tranny problems etc. etc.)... I gave up and bought a 93' 968.

Having invested heavily on the 951, I am thinking of swoping some usable parts to my 968 (turboing). Cost effectively. (I hope to sell my 951 at the end of the day)

Need some advice on what is the best option for me:

Good condition and removable stuff "in" my 951:
- Kokeln DME&KLR chips with LR MAF V
- Kokeln Club Turbo V with LR Dual-Port Wastegate + LR BOV
- Big Reds (Front) + all other accessories (SS lines + adaptor + MBC etc)
- Cat-Bypass, Customed Muffler
- I/C moded and hard pipes
- New piston rings, head with many new original engine parts replaced.
- Idling setup coverted to late 951.
- 17" C2 wheels + spacers
- M030 struts & springs
- 2.5L Motor

Things that are F*&K in the 951:
- Tranny w/o LSD
- A-arms, trailing arms, spindle
- every single interior part, YES.. everyone.
- Body.

I keep most of the old parts and should be able to "transform" the 951 back to its stock condition.

The 968 is immaculate stock. Considering the parts that I already have now (951) and if I do a 968 Turbo conversion, what is the estimated cost? Can i still use the same MAF? Turbo? I/C?

Sorry for the long thread. If you were me, what would you do?

Yes, you can use the MAF, turbo and IC but not sure if the turbo is a good fit for the 3.0. Check with LR on that as the engine would be 20% larger with different flow characteristics.
Ideally, you want a 2.7 head as it bolts on directly. You will also need to lower your compression on the 968 motor to have reliability. So it will require dishing your pistons and shorter rods. All in all I would say it will still cost you in the neighborhood of atleast $6-8K to get it all to work with some of the body mods required for fitting the intercooler.

6 - 8 K sounds reasonable.... btw... what about electronics/sensors?

Do I ditch the 968 DME?

RajDatta

Yes, unless you have some fond attachment towards 968 electronics, no need to run them cause your triggers will be moved to the flywheel like a 944 turbo. 968s have one of their sensors on the cam pulley but you will be using a 2 valve head so no need for this. Use 944 turbo dme/klr setup and clutch and torque tube. The trans can stay 968 and you will be all set. The reason it will cost you less is cause you have most of the parts from your 944 turbo otherwise add atleast another $5-7K.

Tks for the help... 968TurboS

Just a few more questions.

Any good source for the 2 valve head?

What about the Intake Manifold? 951's or 968's?

What about the Head Gasket? are there any available source for WFHG on the 2.7NA head?

RajDatta

Song, you have to look around for the head. The 2.7 NA head is a direct bolton.
951 intake, exhaust and everything else. You will have to port match your intake as the 2.7 head have oval ports compared to 944 turbo round ones.
I am using 3 piece metal gasket from Performance Developments and it works well. No need for Oringing head and no need for WFRHG. Any 104.5mm bore head gasket will work, be it an S2, 2.7 NA or 968.
Let me know if you have any further questions.

And feel free to post here first before you tell everyone else about all the great parts you may be getting rid of! It reads like the best christmas list ever! I call dibs on the turbo and chips! lol

As for the 2.7 ltr head, they seem to be getting harder to find. Have you thought about trying the 16 valve turbo route instead?

Regards,

Songzzz

Yes. Maybe 16V is the better option, since i need the intake for selling the 951 at the end of the day.

However, I am still worried as to how the 16V head is going to work with the 951 DME/KLR and ofcourse the triggers etc.

Sent an email to Powerhaus, hopefully they can think of something.

Songzzz

Got a quote today... still in a choking about it...

Figure it would cost at least 10K..... bump!

hmmm... just wondering if there are any.. japanese pistons or rods that i can use....

RajDatta

I know how to make it work . What is it that you are looking at? 16 valves, simple: go to an S2 head, get SFR to build you a hybrid 968/944 turbo intake manifold, no variocam to worry about, change your clutch housing and torque tube to 944 S2, change your timing belt tensioner to S2 and you are set. You can run this setup with 96 DME or you can go the DME/KLR route using 944 turbo electronics.
All you have to do is ask

RajDatta

Song, I hope we get 1st dibs on all the parts . I could definitely use a few from your list.
There are ways to do it cheaper. Trust me. No custom stuff required. You need to know what are your goals as far as hp/tq are concerned. Song, i have a spare 2.7 head that will be coming off my car if that is what you need. It is currently in my car and setup for turbocharging.

Songzzz

968TurboS... you are Raj, arent you?

Yes. I am definitely going the 8V route and would like to have your 2.7Head. Price?

How much did you pay SFR for the customed Intake? I can send in 968's manifold for the job but not the 951's.... cos it will be needed for the sales of the 951.

List of items to buy (correct me if i am wrong):
- 3.0L forged pistons for 8:1/8.5:1 ( i would prefer 8.5 though)
- Forged Rods
- additional of DME + KLR and harness
- I/C and customed piping
- Additional 951 Header + exhaust
- 2.7 NA head (head job required?)
- Hybrid Intake
- Modify block for turbo oil line etc..

A list of extra parts that I might end up with after the project... any offers?
- 968 DME + harness
- 968 Exhuast Complete
- 968 Intake Manifold
- 968 AFM
......

I am looking at 400 hp with lots of low-end torque....

RajDatta

Yes, thats me .
No need for custom intake if you go the 2 valve route. That is only needed if you want to go for 4 valve head.
Head is fresh and was recently off and verified for tolerences and it is within spec, so no rebuild required. I am currently running it in my car.
Now that you know who I am, would you care to share who you are ?
Also, send me an email directly.

inthe exhaust side. you can take the 951 exhaust headers and ewld on the flanges for the 968 "cheapest route"

im building a 16V T with all new custom parts. the cost is considerable.

try to use as much of the stock parts as possible to keep your cost down.

also the blocks are almost the same. (for the sensor conections) I am dissasembling my 968 engine and relating everything to my 944 944s and 951 parts laying around.

you will get ALOT more flow from the 16V head then the 2v head. but i did hear a roumor about changing the valves. humm.. I have not changed the valves on any other turbo project.. so why should it be different for the porsches.

mike.

STOP ___________

I have just dissasembled (well a few months back) 86 944 T I have alot of the necessary components laying around. intake manifold.. exhaust. and the like. ask if you need anything. 719-492-3229
