that's especially true when talking about LSx engines. They are pretty light.

The real problem with the V8 engines is how heavy they are, it's where the weight is. The center of gravity is so much higher than a flat 6. There's also the issue with length. The V8 sticks even more weight behind the rear axles than the Porsche engine. The Subaru engine however is actually shorter than the Porsche flat 6, and the newer 3.0 Subaru engines have variable valve timing and are even shorter than the 3.3 I'm using.

I dig it... Hope to see you out on the track soon. :)

Not to derail this discussion when talking SBC engines..BUT..

If you do the math..the cg is not "so" much higher for a SBC V-8 than a Porsche flat-six. Certainly not enough to worry about. The extra intercoolers and claptrap on the Turbo places the masses rather high too...and we don't often point out handling ( only) differences between NA and Turbo cars on this basis. Just not enough to worry about and the same with the SBC V-8. Plugs are easy to reach too !!! :)

Wrong too is the assumption that the SBC is very long. All dimensions ( X-Y-Z) are fairly compact, even relative to the Porsche flat-six.

Nonetheless, the Suby 6 you're doing looks mighty fine and I'm intersted in the outcome.

Great Swap, and very nice work so far, I am watching this as I really like this swap. Very interested in how this turns out.

I started looking at this and the wheels started turning.. The wrx guys are buying high $ pistons and rods so their used stuff is cheep, you could really easily swap the pistons for the low compression wrx stuff and then the right turbo, intercooler and a megasquirt.... lets see 400+hp and all the same reliablity....

Very cool project, I can't see why people would even think about deriding you for your powerplant choice. It looks authentic(ish), sounds like a 996 and should run great. Anyway great work and look forward to seeing more.

I look at it this way: Like a cable/satellite channel on TV.

If you don't like the programming then change channels.

Maybe you should have included in the title, "purists, don't read this thread"

BTW...... If you decice to make the engine mount and headers I would be interested....

I don't think that would work - the WRX is a four-cylinder. Perhaps it's the six with two pistons chopped off, though...

What does this 3.3 weigh?
nice fab work! and looking forward to hear how the car runs

I don't have an exact number on the engine weight, but it should be somewhere around 350lbs without the clutch and flywheel. I will get an exact measurement the next time I pull the engine.

The 3.3 engine, internally, is essentially a six-cylinder variant of the EJ22 found in the first-generation Legacy and Impreza.

Not a whole lot new lately (I've been busy with a few side jobs). I ordered some Tarrett solid motor and tranny mounts, a MOMO wheel and knob, and some stainless brake lines to replace the old, cracked rubber lines. I also finished fab on the radiator and fan shroud, and pressure tested it (it held 20lbs with no leaks). The coolant "manifold" was also another thing that I finally finished up and mounted. Now I can finish up the aluminum work for the radiator shrouding and start on the fuel tank. Here's a quick run-down on what I have left to do...


-Fabricate custom fuel tank with factory 911 sending unit. and plumb fuel system

-Finish radiator shroud and wire fan control system. Plumb cooling system

-Send gauges out to be converted for water temp, and numerical oil pressure.

-Wire in engine management harness to engine and gauges.

-Mount battery in smuggler's compartment

-Throttle cable (custom)

-And there's a bunch of little things to make the car road worthy (change brake lines and flush fluid, re-pack CV joints and install axles, ect...)

It's getting close :)

Great looking fab work! Very nice. I am very curious to hear what the flat 6 Suby engine sounds like with the shorty headers and short exhaust. Great project.

Later,

Finished the aluminum duct work for the radiator. I still need to finish the fasteners and a few detail things, but this is basically how it will look. I left enough room behind the rear of the shroud for easy fuel pump and fuel line access. The space for the fuel tank is going to be tight, but I should still be good for about 13-15 gallons... even though it doesn't look like it in the pictures.

I also added a few supports to the engine cradle that tie everything into the chassis through where the rear bumper support goes through the rear frame rail (I always that this design was oddly heavy duty for what it does). Works GREAT! Now with the Tarrett motor and tranny mounts the powertain is nice and snug. I also welded on a few tabs for muffler supports so the weight of the exhaust isn't hanging on the headers

the porsche purist debate seems to come up alot, not sure why, after all, porsche spent 40 years modifying the 911, so why can't we? most 911s probably have a non standard mod anyway, it makes perfect sense, and is totally in keeping with the ethos of the car.
imho anyway.
people on this site shouldn't have to defend mods.
personally i'd like to see someone stick a V12 in the front of a 911!

Is there any new updates on your project?

I'm working on the fuel tank and trying to finish up the wiring. Imm trying to get it running no later than December.

excellent workmanship. a word based upon experience....there will be a tremendous amount of heat in the luggage area...unless properly insulated, sealed off, whatever...all seeking to enter the cabin via the numerous openings in and around the dash. porsche did not seal this area very well at all.if you havent i would suggest that you remove the dash cap and insulate to reduce this tendency... if you have already cited a solution in earlier posts please excuse me !!! did you consider passing the air through the radiator and upward over the hood as opposed to underneath the car?

Subscribed. BTW - is there still a way I can subscribe w/out posting? I couldn't find the link to click - I seem to remember one in the old forum.
