Almost done, if there is such a thing. It's on the road though, just need to figure out what I am going to do about a hood.

Lexan is a interesting option. I did find some FG hoods out there, but they are fairly expensive. I had a spare stock hood in storage and figured I would give it a try. Had to cut out the bracing above the throttle body, but otherwise fit perfectly acceptable for me. Just have to paint or wrap it, but very happy with how everything came out.

You know, it's really interesting. I have been driving this car for a long time, 15ish years I think, on the street and on track and it's just so different with this engine. The turbo motor was no slouch, but it was a total On/Off switch. Which can be a lot of fun at times, but for most "normal" driving, it absolutely sucks. It had around 8:1 compression and off the line with a big turbo, I would get smoked by minivans. It's just so nice to have torque everywhere all the time. It completely changes the character of the car. I do miss the hit of a big turbo, but I am very happy with the V8.

I tracked my 944 Turbo for 12 years before LS2 swapping (first season on track after the swap was last year).

It is weird having torque everywhere, you build so much speed, but it doesn't feel like anything, it's like a weird gradual push and then you're arriving at places way faster than you expected on track compared to a turbo 4.

That's interesting to hear. I guess I won't really know until I go back to the tracks that I have run in the past.

I completely understand - I've driven a turbo-four as a daily for several years. The only good thing about it was how far it stretched a gallon of fuel - I found everything else about it to be thoroughly "MEH..." I MUCH prefer the instantaneous torque of the V8 over the "hit the gas, wait for the damn engine to build RPMs, & spool the damn turbo, & THEN the car finally starts moving!"...

I bet you are still getting mileage in the mid to high 20's on the highway.

That's a good question, I haven't checked yet, so far has just been local street driving. The turbo motor was pretty thirsty when pushing it, but the stock tank is pretty big, so never that annoying. I know some guys will swap in a taller 5th gear from a naturally aspirated 944 to bring the RPMs down and save on fuel on the highway. I am not sure how much of a difference it makes, but must be worth it to some people to go through the effort. Might be worth looking into at some point down the road.

What a great shot! Sure makes me jealous of the euro bumpers. You're running a 265 square setup now right? 265s on 10" rims all the way around seem like an excellent setup for these cars.

Sorry dude, accidentally posted on your thread instead of mine, deleted and moved it.

Yes 265 square on 10”, what a nice balance it gives.

I’ve got a friend with a euro rear bumper for sale, let me know and I can put you in touch.

No worries! Thanks for the heads up on the rear bumper. I am in pretty good shape on that end of the car, I have a GT Racing FG bumper on the car now. A front would be really nice though. Would love to get rid of the U.S. side marker lights.

Finally got around to installing some hood vents. Hoping these help with the temps for now. Going to a bigger radiator in a few weeks.

It was a fun project. I traded a guy some Porsche parts for these. He drew them up and cut them out of 0.080" aluminum on a water jet machine he has access to.

Cutting the hood was a little more challenging than I expected. I ended up using a dremel to cut the corner first and then using a jig saw for the long straight runs.

Hey 9sec. To answer your question, this is where you can find the manual. http://944hybrids.pbworks.com/w/page/1147189/FrontPage

However, be warned, this guy has a history of taking payment and never sending the manual. I don't know all the details, but have heard plenty of cases where people have gotten screwed to the point that the guy's last name has become a verb and people refer to it as getting "Sloaned". Again, I have no personal experience with this guy, I got my manual from someone else, just wanted to give you a heads up.

If you can find a manual for sale, I would go that route. But a great amount of the info in the manual is in the wiki link above. Also, the forum link below is really good as well.

I see that you don't have many posts, but welcome to send me a PM anytime for more information.
