Porsche 944 N/A

[Rannem]

Sounds like a healthy goal!

Wich WG are you going to use?

And where did those lovely OZ's go?

[sumpcracker]

Im using a standard wastegate from a 250, i expect i will shim the spring though, as boooost is wanted.

The O.Z were sold, i just could not keep them nice, i use this in snow/salt and it makes a lot of brake dust. They were not laquerd and i was cleaning them daily. The Azevs are much easier to keep nice.

[sumpcracker]

I have enough bits to get on with it, ive started to strip it, the head would have been off today but the stupid design cam box has sunken very tight allen bolts, which were stronger than my allen key, so I now have to drill the head on one.... tomorow job.

Front is stripped, bumper/bonnet/valance/badge pannel and manifolds & ancilarys are removed.









This week i have also got a full exhaust system genuine turbo (£100) the rear part will be modified though.

[sumpcracker]

More bits.

This is a 250 turbo S clutch kit- (omg another £200)


I need the clutch to take the extra hp (this is good for well over 300 hp), the new fork is wider to fit over the bigger relese bearing. The flywheel is larger in diameter than the N/a this is needed for the bigger clutch. Also there are more timing teeth, so this is needed to use turbo managment.

Also have a mercedes sprinter intercooler, not sure if I'm using it yet. (free)



First of the bling bits ! aqua blasted my inlet and throttle body

(all was stripped and reassembled)

Before-


After-




And stuck the sump in the degreser tank.





Also I have removed the blanking plug form the balance shaft case and tried the turbo oil feed banjo bolt in it, whey...




Plan of action...

1. Remove head - inspect bores (if block is FKD dave has a good spare)

2. Remove bottom end from car, fit clutch and pistons using original rods and bearings (disturb less as possible) refit bottom end.

3. Buy headgasget, refit head & manifolds fuel rail ect (and exhaust if it has turned up > )

4. By this time I should have the cash to collect the remaining parts which are all small jobs, engine loom & ECUs, j pipe and AFM maybe cooler and pipes if I don't use the one I have.

[sumpcracker]

I have AFM from an S, its the same as a turbo one in diameter and the plug is the same, anyone know if it meters differently?

[sumpcracker]

Wastegate came today (not shimmed yet)


Also did a bit more blasting today, though the cam box was de greased and painted as I didnt was sand in it.

[sumpcracker]

I have bought a standard used exhaust to get it on the road , rear section is dansk. its a full system with the waste pipe fitted, should save a lot of hassle , I can mod it later..



I said no blingy exhausts, but this has a blingy tail pipe..



Removed head, bores perfect and block is groupe 1.

[carter]

I really **** the 944's...

But you've changed my mind. Significantly. So much so that I'd consider buying one someday.

Excellent work.

[sumpcracker]

Thanks man.

Got it out in the end, (single gararge not ideal)





Clutch off,now to fit fly/pistons/clutch/sump.



Thats not an oil leak btw, its spilled oil.

[sumpcracker]

The price of all the exhaust gasgets came to more than a Lloyds director xmas bonus, so I bought a sheet of exhaust gasget material, the joints on the crossover pipe and gate are important as boost can be lost here.



Speaking of boost, I have 4.5mm shimmed the wastegate and got a bleed valve & line.



I fitted the rear exhaust section, its going to have to be played with as it sits too low and pokes to much



Engine back in and being built up, the head isnt bolted yet (waiting for gasget) just laid on to cover the block.



Manifold is on though,



Ive blagged an afternoon off, so I hope to get under it and fit the starter/exhaust front and whaterver else can go on without the head.

[thuggie]

love them 944's

[sumpcracker]

Problem time.
I paced the inlet on to work out the hoses(vacum coolant and boost) very simple as I'm deleting the fuel vapour purge system, cycle valve system and venturi system.
As I placed the intercooler in it was obvious it was not going to get any air fed to it.
See-




The turbo cars have a bumper slot like this-




I have no desire to fit a turbo bumper anymore.
My thoughts were to take advantage of the 5 digit plate and do this-



As you can see, the frontal aera isnt massive but its very deep capacity.

[OSSHWA]

Just read the thread from start to finish. Excellent progress you have made!

[sumpcracker]

Thanks man, very nearly there now too.

[Rannem]

I see you have bumped into the same problem for cooling the intercooler, as i did when the turbo engine was fitted in my -83 944. The result was cutting ventilation holes in the front plate.. Not ideal, but efficient!

Anyway.. Like the progress alot! I know how hard it is to do such fixes in a single garage..

Are you running the kkk26/6 or the kkk26/8 turbo?
