I'd be interested in your build intentions. Is this for a racecar? Do you have any diagrams of your intended build with location of intake, turbo and other ancillaries? Rear mounted cooling has been done but as far as I'm aware it was only in the Orca series cars. Cool project but I wonder if the desire to have the closest proximity of turbo to motor isn't by virtue of a knock-on effect, creating other dilemmas such as rear mounted cooling setup? Perhaps I've misinterpreted your intentions?

That being said Alan, I think sometimes I forget this is a custom job and on top of everything yall have day jobs as well. I know I really appreciate all the work being done; Sometimes it's just hard to contain the excitement of how awesome this swap is, and that we have the opportunity to do exactly what you're doing. Usually whenever I see threads like these, it's a one-off job & the fabrication is too complex to follow for anyone else who wants to do the same thing.

Rear quarter window regulators on a Porsche 944? Better sell some blinker fluid with it.

Lol, sorry. We didn't realize that he was referring to the glass. I can assure you that we are not spam. We're a general regulator rebuild shop responding to multiple threads for window issues. On some Porsche's there are rear quarter panel regulators, but this was an honest mistake.

Intake manifold: waiting on the second prototype, which was cast by a different supplier. In photos, it looks much better than the first one. It's not quite to the quality level required for a production run, but will be better for our dyno tuning than the one on Mike's car (runner ports line up better with cyl head ports).
Coolant flange: I'm working on yet another iteration to make it easier to find off the shelf hoses that will fit up without adapters. We will be cnc machining the next prototype out of 6061-T6 instead of 3d printing. The carbon-filled nylon did not hold up as well as we had hoped.
Tensioner & crank pulley: I have received the "lipped" tensioner pulleys from iAbed. Mike and I plan to install and dyno test his car again soon to see if that does the trick. Mike's still waiting on delivery of the TTRS crank pulley. We're going to try to dyno test without it first to see if it is even necessary.
Thermostat housing: I have billet adapters from iAbed that let us install 1.8t thermostat covers (the part with the rad hose barb on it). The clocking of the adapters is not quite right, so I owe Issam some dimensions to change the design a little bit.

Overall very exciting. Do we have final pricing for the oil pan assembly yet?

Sorry, I don't have final pricing yet for the oil pan assembly. Still shooting for under $1000. That includes the modified upper pan, complete lower sump with trap doors, complete pickup tube assembly, and hardware.

Got it. I think that covers everything for the NA build unless there's something I missed. I've been stocking up parts little by little over the past few months, I think all that's left now for me is everything listed above, RTV, VW valve cover sealant, and the ECU / wiring. Any news from PE about electrical kits?

We don’t have a final number yet. Still some tuning to do on timing, and the intake manifold we’re using now isn’t great. But the highest number so far was 172 at the wheels on a Mustang dyno that notoriously reads lower than other brands. My guess is we’ll pick up another 10% with tuning and the next intake. So if that’s true, it would put it around 190 rwhp on the Mustang dyno. We will also do some runs on a Dynojet to see the difference.

PE has been busy getting ready for SEMA since we left. When they get back, we’ll finish up the tuning (hopefully with the new manifold).

Hey All,
I've been cheering for this project for years, still following it weekly now. Fantastic work Alan & Mike, I'm properly impressed! Very good show on youtube, too! Cheers for the entertainment!
Congratulations for getting the swap done! _Huge_ accomplishment and very nicely executed!
* Can you really run these engines at 8500 rpm on stock internals? First post says so but couldn't find any evidence of this myself.
* Your dyno run is really low on torque, even the stock engine on the IE site was over 150 wheel torque. Is this because of the intake manifold? Or maybe not enough back pressure from the "exhaust"?
What torque do you guys expect on the NA build?
* Could you please start the next dyno run at 2000 instead of 2500 rpm? That region is pretty important for my normal driving.
* Is there a known place for good head work for these engines? Would it even make sense? After all, the stock head flows just as well as a Lindsey stage 2 and you keep making power at 7000 rpm at the moment.
* Are you planning a supercharged version? Do you see a way how/where a charger could be mounted? It's very hard for me to guess anything from the pics and videos.
* Will you be offering this as a crate swap kit?
A 230 hp / 200 ft lb (both crank) NA engine with an 8500 rpm redline would be a dream!
Keep up the great work!
