3.2SS Turbo Build
 
Well I think it's finally time I posted my build thread. A little background on the car and myself. The chassis is a Signature Edition (however far from original, all I have that remain from the Signature Edition are the color, wheels, and steering wheel) originally owned by my grandfather who purchased the car as the second owner in 1978. After driving the car for a few years, he swapped the engine for a 1979 SC engine and pretty much left the car untouched after that. My father then acquired the car, with the intent of making the car his track car and amassed a pile of parts that never made it onto the car.

http://forums.pelicanparts.com/uploa...1531763556.jpg

Eventually, the vehicle came into my possession in 2002. I parked the car from 2004 to 2014 and did not touch it while I completed college and the early stages of my engineering career. In 2014 I decided to tackle the car and begin working on everything I had always wanted to do but could never afford. Luckily for me, I picked the perfect time to start the project as prices for parts were beginning to skyrocket.

I had always wanted to build a 3.2SS from the 3.0 and I decided to tackle that project first. Fast forward 2.5 years and I start the engine for the first time with CIS, quickly realizing there was still more work to be done. Shortly there after, I started work for AEM Performance Electronics and quickly decided to convert the engine from CIS to EFI using the AEM Infinity. A little help from Rasant Products with his EPM adapter got the project underway. I ditched the CIS manifold for a Carrera Intake, made my own fuel rails, wiring harness, and a few other items needed to complete the project. 1 year later, the converted engine makes it maiden voyage on a 700-mile round trip to Rennsport Reunion V without a hiccup. Power on the Mustang Dyno at the office resulted in 204 WTQ and 194 WHP. Not bad but I wanted more.

I have always wanted to turbocharge the engine and after talking with a few manufacturers, I decided to bite the bullet. I found a set of used B&B turbo headers that I modified for a T4 flange and a Tial 44mm V-band wastegate. Borg Warner supplied me with a S360 turbo and I utilized a prototype Evo X intercooler we had lying around in a scrap bin at the office (sealed charge pipe inlet and oulet so no debris was inside). I fabricated a few parts here and there including a brace for the turbo as well as the engine tin piece. A Turbowerx electric scavenge pump was utilized with a drip tank I fabricated. Chris from Wisecraft Fabrication in Orange County put the icing on the cake with a beautiful exhaust built to my request. I still have yet to dyno tune the engine at this stage, but will in the near future.

No critique here as everything is awesome........except the 915 trans.

Might have a short life behind that beast of an engine.

Fantastic!

I'd love to get a ride in this thing. I've been considering turbo for the last three months but have yet to pull the trigger.

9.5:1 seems fairly high compression with no knock sensors or twin plug. Any issues on hot days? Are you running a turbo tail to fit that cooler? Cheers!

Tippy 07-16-2018 10:50 AM

I'd admit, I got excited when I saw you mention an Evo X IC fits. Clearly you had to modify the inlet 90 degrees.

I did something similar. I bought a Treadstone V8 IC good to 1300hp. I had to lop off both the inlet and outlet pipes and reorient to match the 911 configuration, but it was well work it.

Correct, the left hand tank had to have the inlet rotated 90 degrees but overall not too much effort to make it work. Inlet temps are ambient all the time when moving, they will creep when the car is stationary but drop right back down once the vehicle is moving again. I was originally going to run non-IC but very happy I opted against that route.

Absolutely, any time! There is a knock sensor on the engine, works quite well (on the throttle linkage stud in right of this image):

I also run a blend of E85 and pump to help keep the knock threshold of the fuel in check. I also have an Elephant Racing widemouth cooler in the fender with a temp activated fan. I never see oil temps above 190F, even in stop and go traffic with an ambient temp near 90F.

I love the S360, I have the 0.92 A/R T4 divided hot side and see 10 psi by about 3000 rpm. I must say, the spool noise from these BW's is highly addicting and the turbo itself is a very robust unit. It is a very tight fit back there tho, but it fits...barely. I'm already contemplating upgrading to the S366 SXE for the 360 degree thrust bearing and billet comp wheel alone...

What a fun build. Probably a bit scary on those 6" cookies in back. Total sleeper with those matching sugar scoops and cookies. It'd be really cool if you could get a custom intercooler built that fits under the original decklid - I've seen it done.

Add bigger rear wheels and tires to your turbo trans wishes. :-D If you were really trick, you could buy 2 more 6" cookies, have them widened to 7" wheels with a 32mm offset. Then you could run a 225/50 in back.

Flynt 07-18-2018 07:10 AM

I love the stock look, down to the cookies. And true narrow body - not even Carrera flares!
Contemplating something similar for my purple '75.
I have questions.. Does the back step out on you when you hit full boost? Do you feel like the car is still "balanced" with so much power on tap? Do you have any brake or suspension upgrades?

If you're ever in San Diego I'd stand in line for a ride.

Hasn't been on the dyno yet, been sorting out a few minor issues and waiting for the exhaust to be completed. Have an oil leak to fix up and then I'll be ready for the dyno in the coming weeks. Goal is to be right around 350WHP or less. Engine is on a very safe and conservative tune at the moment. I estimate the power to be about 250-275whp at the moment.

I know TK makes one that fits under the duck and will tailor the design to your individual needs; however, I can't justify spending over $2k for one when I have something that works well and doesn't look half bad. Air temps never go above ambient with this configuration unless the vehicle is stationary.

I have a set of 944 7" cookies but would like to get them color matched before I run them. Surprisingly with the R888 tires in 205 width I do not have traction issues. I do plan to run a boost by gear configuration with the Infinity so gears 1-2 run off spring pressure (5 psi), 3rd gear sees 7psi, and gears 4-5 see 10psi. Currently, I have boost control disabled and am running strictly on spring pressure.

That was the idea! I love the idea of a total sleeper. Currently I do not have traction issues but I am running low boost and a conservative tune. We will see how it changes after the dyno session. I will be sure to post a video of the dyno once I get to that point.

As far as suspension, the car has Koni's, adjustable sway bars front and rear, stock torsion bars, and Stoptech Level 2A brakes in the front with matching pad compound in the rear but with stock rotors and calipers. I'll be sure to let you know if I make down to SD!

I'll be adding some Loctite to mine upon installation, just for good measure.

Heads are done with AASCO springs and Ti retainers, machine work done at Vellios Machine Shop. Also had them chamfer the heads for the 98mm bore. Not entirely sure it was necessary with the JE's but opted to have it done anyway.

'76 911S 3.0 08-02-2021 10:57 AM

Hi Lukas,

The engine is back together and getting some of the finer details ironed out. With the addition of the ring inserts on the exhaust ports I've had to ensure the mating flanges for the header are perfectly flat and that has been troublesome for the machine shop I brought them to so taking them elsewhere in the hopes it can get sorted. I have 2 flanges that are still not perfectly flat (verified this Prussian Blue and torquing the headers to the heads). Once that is all sorted, the headers will go off to ceramic coating and then everything can begin getting assembled.

I had the builder retard the mechanical cam timing just a bit from spec, 1.1mm vs. 1.26mm (964 cams) to shift the power band higher and keep the torque low to help try and keep the 915 in one piece.

Also had the waste gate run shortened up quite a bit as I am not concerned about it being located in the factory 930 location.
