really well done

Ryan_Cunningham 07-23-2025 12:29 PM

ECU Doctors has them and recommended Bosch part 0 261 204 376 with Driveblock removed. My research shows it’s for a Tiptronic 3.6. They said it should be an issue because the ECU can sense if it’s a Tip and a Tip has its own ECU.

Anyone know for sure if it’ll work ok with my 915? They said if there are any issues to send it back for up to five years and they’ll make whatever modifications that are necessary.

For transmission durability, I guess it depends how you treat it. I too heard people cautioning me about the 915 but I haven't had an issue nor do I know anyone with a 3.6L that has grenaded their 915. I did go with an '84 euro 915 (not my stock magnesium cased one) and I didn't add an LSD hoping to stress the transmission a little less, maybe having a little wheelspin here or there on one wheel. 911s get such great traction anyhow and I don't track this car, so the lack of LSD is hardly noticeable.

There is a lot of torque going thru the cwp in the lower gears, w/ a 3.8 RS at wot in 1-3 I could make the trans weep

The original mg. /44 was better in this respect as it came stock w/ a steel girdle stabilizing the si/o shafts, I also went w/ a /67 for the trans cooling feature but recomens adding a steel girdle here too.

There are some minor differences between the tip and manual but a tip ECU will work

on a 55 pin DME I think that it is pin 44 that activates tip coding

Awesome. Thanks Bill. It’s an 88 pin but I’m just going to put you on speed dial until my swap is done.

Thank you both! Drives amazing but now I'm thinking it might be time to see what a modern Porsche race car is like. But sadly prices of modern GT3s are so insane that may never happen.

trans is still #42

I think that you need #56 & 82

the tip has a different way to control idle from the manual, I think I recall a TPS and stepping motor on the throttle

Getting closer… soon to be IROC tribute. Hope to be running next week after ECU comes back from specialized ECU. Then off to paint, wife got to choose one of the IROC colors, she chose Magenta, will see if I can commit to it soon enough. 1982 chassis with 1989 930 turbo G50 torsion tube and trailing arms grafted in.

That exhaust looks exactly like the one I bought from Fabspeed, and I do mean exactly. If so it's great, best I've ever heard including the ones I've used on my 993.

Only nit is that the tips are a little weal, appearance wise

As is typical, it looks like you were probably right. Unless we can find a way to move the exhaust higher I think I'm going to have significant ground clearance issues. I'm not so concerned about the heat exchangers, but the I'm fearful the exhaust will hit on any speed bump or leaving my steep driveway.

Congrats man! It's in there. Mine is tight like that too. Zero clearance on the vram to go higher.

Your fan scavenge thing is cool looking. Haven't seen that flavor yet. I heavily modified the rennline CF tube on mine but it leaks at the bottom where the exhaust side and it meet at the tin opening.

It's far easier to make room above than to fab a custom exhaust which fits up higher.

Is that the new version of Fabspeed on yours?

If so let us know how it sounds, i love my 3yr old console version.

Haha, thanks. It’s taken WAY longer than anticipated.

Any issue with your exhaust bottoming out on speed bumps? Thinking about raising the rear 10-15mm and trying to rotate the exhaust to get a bit more clearance before I just pull it all out and buy a new tin.

I want to start this thing!

I had to mod the heating connection where it went through the tin/cf, I used some silicon tube from a turbo intake. To join the upper and lower sections On this one I used the oe RS plastic tube.

Ok I feel like a luddite.........CWP?

AlBackus36 08-18-2025 11:42 AM

After looking at the pictures of the varioram at the 'proper height' with the package tray modified, it would appear you are committing to a partial engine drop to get the intake off the car? I can still get the manifold off the car at the Timmon's height.

Anyone here with the TPC supercharger instead of the Rassant intake? Anyone tried both?

AlBackus36 10-18-2025 11:48 AM

Can we talk about the 3.2 cross bar and console again? Is the top of it at a different height than the 3.6 cross bar? Anyone ever measured the difference? What is stopping someone from simply removing the spacers and lifting the aft end up the 1.25 inches the spacers force it down? This has been bugging me.

The 3.6 tin is sized to complement the lower position of the egine, both the tin and mount prevent a higher . ie stock engine position.

w/ a vram a modified package tray is more desirable than the droopy drawer ghetto look

which can be ameliorated w/ a custom, read expensive, exhaust setup.

just my opinion but since I've had 964, 993 vram & 993 non vram the 993 non vram is the best compliment to the 915 and early chassis. The vram has what I call a Camel hump torque curve, the cammed n-vram is more like a pouncing tiger. You really don't miss the lower rpm vram torque, and you can appreciate the higher rpm tiger torque curve. a 3.8RS is very hard on the 915 in the lower gears.

AlBackus36 10-20-2025 02:58 AM

Thanks for the pics and insight about the different motors, Bill! I could've sworn my 3.6 tin was all 'inside' the engine cutout, but now I'll have to go look again. If it is, the only thing stopping me from going higher is the V-Ram.

Joeaksa 10-20-2025 05:57 AM

Here is an "old school" version! Forgotten just how old this 3.6 setup is but it came out of Bill Verburgs car at least 10+ years ago and no idea how long it had been running with him! Only change from when I got the motor from him is the B&B exhaust system.

Joe that's a 964 aluminum console w/ the 964 crossbar, It requires the 1.25" spacers discussed above.

For some reason I thought that it has the aluminum console w/o A/C but I guess not.

You'd have a problem using the 3.2 console because of the crank damper w/ 3 sheaves.

AFAIK there are no single sheave dampers available these days. At one time there was a 964RSR damper w/ single sheave available but no longer.

Bill, thanks as usual for the info. I had forgotten the status of the engine and it seems for good reason!

I did some research and realized that its been longer than I guessed at. I installed your old 3.6 in the 911 in 2003/2004 and its been running nicely ever since!! Really surprised that its been 22+ years! Guess time flies when you are driving a sweet 911!!!

I believe that this is a photo of your engine as it arrived here in Phoenix in 2003.
