One of the most gorgeous set ups of all time right there.

Due to temps behind the wheel well, I would love to relocate the turbo WAY down the road to the area under the license plate, use braided carbon/kvlar as an air duct/shield and expose it like that. Thats item 10,003 down on the list haha.

Looking like it's coming along pretty good. I'd be interested to see how long the D2R CO's last. I've yet to see anyone report back on long term reliability on some of the Asian made CO's on the 996 particularly.

Hate to be a downer but I don't think you can get more than a few laps in with that turbo setup in a track environment at a time. Even the factory turbo's have a hard time sustaining multiple hard laps without having temp issues and such. This is one of the reasons why NA is preferred for track duties. For DE's, I'm sure it will be fine though.

Are you planning on getting wideband and EGT gauges? If you're not upgrading to solid mounts, even an aftermarket knock meter might come in handy.

Hopefully this will be wrapped up in a decent amount of time. I'm still following a couple other members and they're still not done yet.

Yes, I am getting a wideband and boost gauge. I would like to try and start the car in less than two weeks. I am dropping the motor this sunday and going from there. As for the track, yes, i know heating is a major issue. Cayman guys destroy their oil feed lines to the turbo all the time if they are not careful. I am currently trying to think of a good way to feed air into the turbos. Luckily I work at a place that sells composite material. I am thinking of making some sort of air scoop underneath the car that routes air to the turbos and then have it exit through a "Turbo Style" rear bumper. It would take some time to create from composite but I have already started designing an aluminum style one.

Personally I love the RUF CTR style NACA ducts on the sides.

Looks cool but not quite my taste, have you ever seen them on a WC 911?

I don't know who makes these scoops, but I've seen them on a couple cars:

Actually NA is preferred because it delivers power evenly and is easier to drive. Turbos don't having any issues racing. GT2 class Porsche's were all turbos until the RSR replaced them due to other manufactures like Lister making them uncompetitive.
Superchargers are harder to keep cool. Though I bet the Chevy engineers have figured a way around that with the new C7 Z06

Uneven power delivery was true awhile ago but no longer an issue with modern technology. I should've clarified on the turbo not being suitable for racing, I was pertaining to street based cars. F1 and Indy had turbocharged cars running on the ragged edge and driven hard but those were race turbo engines and you'd be lucky to make them last more than a race in some cases. It will be interesting to see all the new "M" cars with 6 cylinder turbos compete in various racing series like the Touring or GT World Challenge Series. I know the Nissan GTR in the Blancpain series went with a NA 8 vs the normal turbo 6.

Ok, So i dropped the motor, I am replacing the plugs and serpentine belt in the AM. However I am missing the oil feed line from the block to the turbo.



Do any other TPC users know the specs on that line? I called TPC but they are out at Sebring this weekend so that may hold me up. size, connection to turbo and connection to block, and length.



replacing the plugs, and then the injectors tomorrow.



Started attaching some of the exhaust manifold.

Also, some things I need to approach in the future and am curious because the TPC instruction don't mention anything about these...

These two things need relocated, did you guys just unbolt them and move them back? The picture A is in the way of the intake pipe/MAF pipe. Picture B is in the way of the intercooler.

Finally, Where is a good place to splice/hook up the power for the water pump? I am sure I can dig around and find one but if there is something better than what meets the eye I would love the know about it. I see where I need to start the loop into the pump but do I just run it right back into the same place indicated by the blue arrows?



so it would go Out that pipe, to the pump, then from the pump into the IC, then from the IC back into the inlet (end?) pipe...?

NineEreven

I am kinda curious because it seems as though the third radiator and IC are on their own "loop", Just trying to figure out how they suggest configuring it because there seems to be more than on way to do it. I thought the pump was only to feed the IC and you connection all three radiators in a chain up front. It seems that is not the case and that the 3rd radiator has its own lines run through the car. hmmm.

I bet you haven't seen those in any other car, because I only did one set.

But similar ones do exist, at least by RUF and 9ff. And one Swede has made his own version too.

NineEreven

I am going to do go center exit exhaust on a cup rear bumper, with one of these in the side...

not those EXACT ones but very similar

That Bisi build makes me happy in the pants... good luck w/ this build.

Tbred911

+1 !!

to date only porsche has the formula for turbo motors on the track... surprised to hear that Nissan went with V8 on their GTR... that should tell you something... I too am curious about the v6 turbo M3 coming out..

at the end of the day if you focus on cooling and monitor temps I'm sure you'll have a lot of fun keeping your sessions to 20 min max on hot days

good luck with the build

NineEreven

Thanks! I can only hope all goes well. It is a fun process but I am so anxious that I am starting to rush it. I need to keep calm and enjoy the process. Hard to do at times when the light at the end of the tunnel is so close.

Thanks, I have some good ideas on how to keep it nice and cool. Once my friends lift is finished being installed I will lift the car up and rout some cooling ducts to the hotside.
