Another 944 Turbo Engine Rebuild Thread

Who said I won't install a dual port wastegateWait a minute, you won't install a dual port wastegate but you're going for a max power boy racer Japadoodle doo rear wing?
Installed the original wastegate just to get the car up and running and to allow me to drive it this year
Plan might be to install the standalone ECU over the winter which will require fitting a dual port anyway...

That's a very nice rear spoiler, where did you find that? You might want to fit a front splitter as well though, if you plan on exceeding 160, ask me how I know

It was an american guy living in Germany on Instagram, he has a crazy looking 16v Turbo based on a 968 engine. He had several of those spoilers for sale and had them made locally in Germany as far as I'm aware. Not long after I bought it though his Insta profile disappeared, which I thought was strange as it wasn't a scam as I received the spoiler...That's a very nice rear spoiler, where did you find that?

Looking at getting a front splitter, just not sure which one to go for yet, Club Autosport, Pro9, and a guy on Facebook supply them.

I thought about making one out of marine ply, and mounting it between the front airdam and undertray. The 944 turbo is quite neutral regarding front lift at high speed as standard. Introduce more rear downforce and that could change.

I would have thought that about kongsodoken, then he took an angle grinder to the bodywork on his car.Wait a minute, you won't install a dual port wastegate but you're going for a max power boy racer Japadoodle doo rear wing?
Time for another update!
Been a fair few ups and downs recently, and I will admit I did almost shut the garage and leave the car in there for the forseeable future!
First off I removed the rear spoiler and hockey stick trims in preparation to fit the carbon rear spoiler. Spoiler alert I couldn't fit it so the original one went back on, I also had to spend time repairing the fixings on the hockey stick trims. I ended up using JB Weld, now this might be a bad idea as it might be too brittle but I've got a roll of black gaffer tape in the car in case I need to stick them down in an emergency.
Looks like I may have been scammed on the carbon spoiler, after speaking with someone else who makes spoilers, he was also offered the same spoilers and was told by the seller that there was an issue with the fittings. Basically the uprights have had the tapped holes made in the wrong place so the hinge doesn't line up. Being carbon fibre, it isn't just a case of drilling and tapping a new hole with a helicoil either. Going to take it to my engineer friend and see what we can come up with, either modifying / making a new hinge or modifying the upright.
Good news I've now done over 500 miles since the rebuild!!!
Bad news I've been fighting a problem which I believe is air in the cooling system, I'm hoping this is now almost sorted.
The car spewed coolant on the floor 2-3 times now, so I've probably run it up to temp and bled it over 5 times. The last few times I left the bleed screw open for longer than I had before (didn't want to make a mess), and I did see air bubbles rising from the radiator into the reservoir tank.
I ended up replacing the radiator fan switch (which possibly made the issue worse adding air into the system), the old fan switch tested fine in a pan of boiling water, so lesson learned. I also ended up snapping the radiator bleed screw, interestingly though I found that BMWs of the same era share the exact same bleed screw only it's black instead of blue! Little trick to get the broken bit of bleed screw out, heat up a flat blade screwdriver until it is very hot and stab it in the remains of the screw, and voila!
I did find one other problem which might have not helped with the coolant spewing over, the right hand side radiator fan had an intermittent connection caused by a loose/broken connector. When I tested the fan relay and switch, annoyingly this all worked, it was only when I unplugged the fan and noticed there was something wrong with the connector, you can see where it was arcing. Temporary fix with some spade connectors and insulated tips, and new plastic connectors ordered.

Next I got around to installing the replica Cup 2 wheels and Yokohama Advan Sport V105S tyres, I think they look great. Ride seems to feel much improved as well, although the steering now feels very light (and the front wheels need rebalancing, a job for next week).
More bloody bleeding, you name it I've tried it apart from the vacuum fill (I used my pressure tester to push the coolant through as well).
500ish miles time for an oil change and switch to Valvoline VR1 Racing 20W-50, the oil still has a little bit of the Liquimoly assembly lube in it hence the colour/texture (it is a moly-based lube).
I got so paranoid about the air in the coolant I got a headgasket tester, the fluid stayed blue though.
My A/C has stopped working, only leakage I've found is the body seals on the compressor unfortunately, a pity as the compressor was working fine, just the seals are no good. So managed to get a good deal on a new Denso compressor which is supposed to have newer type seals for the newer refrigerant types.
And finally just for you Stuart, picked up this bad boy on sale.

Re the spoiler, I've posted on here a few times that I worked for Lola in the 90's. One of my jobs was building the carbon fibre tubs, and sometimes the tub inserts that we screwed the suspension mountings into, weren't where they were supposed to be. Then we drilled a hole, and pumped some stuff in to replace the missing inserts. Not sure what it was, but it set pretty solid. Also I think the holes in the later bridge spoiler hatch glass may be drilled in a different position. Finally what offset do those Cup reps have, they seem to fill the arches more than my genuine Cup 2's.

I used to run a set of those, pretty decent and they supported a good selection of more modern tyres.The replica Cup 2s are Mille Miglia, they fill the arches better, but you can see the casting isn't as good quality as the genuine wheels, they are slightly heavier as well. I'm still looking for my ideal wheels.

I quite like the 18" Carrera wheels, but that design needs big front brakes to look right IMO.The replica Cup 2s are Mille Miglia, they fill the arches better, but you can see the casting isn't as good quality as the genuine wheels, they are slightly heavier as well.

They are one of the wheels I've been looking at
I might have a pair of those somewhere
need to find out what my mate is doing as he was supposed to be stripping the paint off them for me and removing the slide plates (someone already had a go before I got to them and rounded the bolt heads).

Another Turbo that I thought about buying, until I had a drive in it. Always liked the wheels, though I think spacers may have been used. Not too heavy for 18" wheels either.They are one of the wheels I've been looking at

Ahhh Wuf - I remember that car, used to belong to Rick.
