putting a 3.3 in my SC - Page 9

The owner of SDS, Ross Farnham, has his SDS system configured for a turbo 3.3
Subaru engine which he will use to drive an aircraft. He would probably be a good guy to work with. Here is a link,,,http://www.sdsefi.com/aircraft.html

Yeah, I forgot to mention SDS. I am actually seriously considering them when I do go to turbo charged because they are familiar with EG33 specifically.

kcpaz · 10-21-2007, 01:45 PM

while searching their web site, I found this little piece of info...

EG33 long block, no accessories or intake manifold- 265 lbs.

So with an alternator and intake manifold, we are probably righ at 300lbs.

I think the 3.3 fully configured weighs in just north of 350, as the 3.0 is said to be 350. Nice thing about the 3.0 is is that it's a little lighter and shorter which would help with balance. Less weight hanging off the rear end.

Still, like you say, the 3.3 is less expensive which matters for most of us.

Ross is a very interesting guy, he spends quite a bit of time a Van's Aircraft forum. He is very knowledgable and friendly, and posts often.

By the way, how about one of these instead of a turbo system? http://www.rotrex.com/

if I were going to do forced induction, I would definetly go with turbo power. It's simple and efficent.

I double checked the weights of the 3.3 and I think you about right at 350lbs. Outback Motorsports (Out Front Motorsports now) says that the 3.3 Subie weighs the same as the Honda V6's and I know those are 342lbs with no clutch or flywheel. They also say that the 3.0 is about 75lbs lighter than the 3.3 but that seems a little optomistic.

Some descent progress this weekend. I basically finished the cooling system (accept for one -20 fitting that will be here on Monday) and fuel system (accept for the vent hose on the fuel tank). I also removed everything in the front of the car so I could do some serious cleaning. It's amazing how much of that 30 year old dirt was there. While I had everything out, I took the time to clean and install a fresh air system, and the hose that will feed hot air from behind the radiator, into the center vents. The only thing left to do under the hood is mount the battery, and install the cover for the smuggler's compartment. In the back, I only need to mock up an air intake and then the engine/tranny are ready to be pulled so I can do some of the same cleaning, and install the flywheel and clutch. Then the only major thing I have left to do is the engine wiring and a little wiring for the chassis. Obviously there are a bunch of little things that won't seem too glamorous in pictures, but I finally feel like I'm getting close!

That is a work of art!!!!

Blanco · 10-28-2007, 08:41 PM

Very nice. Interesting.

There is a gent here in Atlanta, GA that has/had? a Suby powered 911. It was a cool ride.

I really like your work.

rrnixonjr · 11-02-2007, 05:06 AM

Have you heard of this company? http://www.ecutune.com/

They make a chip for the 3.3 engine.

kcpaz · 11-02-2007, 07:26 PM

Yeah, I'm on an SVX forum where the owner posts frequently. I will probably buy a stage two chip when I go to forced unduction if I can't afford a stand alone system.

..Just a concern about your decision to go with a front style cooling sysyem......

Specifically, do you imagine what the result would be with a rear location
for the rad(s) - so as to alleviate all that fabrication on the bonnet area and removal of the fuel tank of previous 21 gallons ?

With talk of forced induction - and weight balance concerns - it appears you had to choose the bonnet end of the car.

kcpaz · 11-04-2007, 05:33 PM

Yeah, the weight balance was a huge part of the decision, as was the future of forced induction (I will run an intercooler in a turbo tail later on). There is really no extra room in the back of these cars for a radiator, and even if there was, it would have to be a horizontal design and those types of systems can be problematic... specifically when it comes to getting all of the air out of the cooling system. I had also considered linking multiple smaller radiators in series (kinda like the 996/997 cooling systems) but that would involve even more permanent modifications to the chassis, making it less of a bolt-on alternative, and would also make it harder to return back to air cooled later on if someone wanted to. The fuel capacity is really my only concern. I am hoping that the extra weight in the nose might actually help with handling, but I won't know exactly how much weight has been transferred until I get in the scales. Also, remember that the engine will be a bit lighter than the stock 3.0 so that may help too.

As for the smaller fuel capacity, in the future I will build a version of the same fuel tank, only with an extension that will cover over the smuggler's compartment. This would require a remote fuel fill through the hood, but it will also add a few more gallons to the tank.

Anything new? More pictures? Hope the project continues to go well.

jwernquist · 11-14-2007, 05:50 PM

Thats a cool project. I had a 94SVX-LSI , I absolutely loved the car, my wife drove it daily until she rear ended a truck fractured a trans cooler line of some sort and fried the transmission on the way home... I wasn't going to dump 4500$ for a trans at the time. Those 3.3 Subie motors were great engines. Unless you had to get parts for em!

I like the idea good luck on the project.

Things are going great! I have snapped a few pictures of the recent progress, but nothing earth shattering. I pulled the engine/tranny so I could install the clutch/flywheel package. I also had to remove the fuel rail x-over hoses so I could weld on some -6 fittings. I did get the ECM mounted in the chassis but the pictures I took kinda sucked. I will have to get some better ones in daylight when all of the wiring is done. I made the manifold for the throttle bodies and the air box for the air filter and MAF sensor. It mounts where the oil tank wend and draws air through the existing hole (I guess you could call it a cold air system). I sent the oil temp gauge to North Hollywood Speedomoder to get the gauge converted to numerical values so I can accurately calibrate the fan controler and keep an eye on the water temps. I made an aluminum cover for the smuggler's compartment and a tie down strap for the battery. I'm waiting for some terminal connectors to come in the mail so I can re-wire the battery. Here are some of the pictures. Again, nothing all that exciting, but it's progress. If all goes well, I should have the thing running by the end of this month

kcpaz · 11-14-2007, 06:19 PM

oh, I also sent the motor mounts and tranny mount out for powder coat, and I had to make a custom alternator mount to slightly raise the alternator so I could fit a stock VOD sending unit under it. I worked out great because I needed to uncrease the alternator belt length anyway because nobody makes a 5 rib serpentine belt in 29 or 30 inches. With the custom bracket, I was able to fit a 32 inch belt just fine.

rrnixonjr · 11-15-2007, 05:10 PM

Thanks for the update! It looks awesome. Can't wait for the next installment.

ianc · 11-15-2007, 06:02 PM

Continually amazed at the workmanship...

Awesome work!
I am really impressed with what you have done!

As for not being a P-Car ... well after Porsche went water cooled, I don't see what the big difference is besides the label on the engine and that you have a different feel than what comes out of Germany.

I realized a while back that my previous VWs were water-cooled and not technically a VW because they weren't air-cooled. But who says that now about Porsche or VW?

hehe, I am still a purist but dammmmmm it's still a flat6 a boxer !!!

Dude, keep up the good work!

Awesome project.

I haven't started my bastardization yet, but I picked up a pre-bastardized '66 912 for $500cdn (complete car (mostly in boxes) with a rebuilt 1.6L also not in the car) ... 225 fronts, 295 rears. I don't know what the PO had in this thing, but I DOUBT that 1.6 could get 295 turning

I figure I can sell off all the Porsche stuff I don't use to pay for the whole car. Rebuilt 1.6, 901, wooden steering wheel, webers..etc.....etc....etc...

I'm gonna try to use a WRX motor tho (will need alot stronger tranny then the 901)

I'm not sure if you mentioned it, but I read somewhere that Porsche helped Subaru design their H4's, so maybe that will calm down some of the "Purists"
