C5 Bellhousing to 944 Torque Tube adapter plate incorporates the C5 Hydraulic Throwout Bearing. The only difference between installing a SBC/LT1 or the LS/4.8/5.3/6.0 engines is the thickness of the pilot bearing adapter. You can literally switch the bushing out and swap in any Chevy v8 engine you want...

There is actually more room in the rear area to work on it than the 4 cylinder.....

So you lower the crossmember about an inch to make up for the higher height of the engine? I just lowered my car an inch all the way around so would that mean that my car would scrape on everything then. I think this is perfect for my little 924S.

I am also in the process of doing this very swap, but with a LS1 out of a 99 Vette. I am not a fan of the sub 10k swaps being classified as Junkyard Dogs. My install will have Just as clean, if not cleaner than 90% of current installs, and current inverstment is about $5K still need headers, engine sensors, coils, clutch disk etc so probably another 1K... and thats for my entire car, not Just the swap.

If you lowered your car, then you have a bump steer problem if you didn't install a bump steer kit....I'm not sure about 924S, but I also just finished designing a "NUKE-PROOF" Bump steer kit that uses 5/8" Teflon Heim joints and inexpensive Toyota inner tie rods.....1/2 to 3/4" Xmember drop is needed depending on car( They are all Porsche hand built and tolerances vary)
Puts the 944/911 Bump steer kit to shame....You have to drill and REAM your spindles to 0.625" (5/8")
Adjusts bump steer 3/8" up to 1.125".....

Inexpensive Toyota tie rod fits the 944 Rack perfectly and even has the catch boot machined in the right spot from factory......

If you're interested in a 5.3l, try to find the L33 High Output variant - all alloy block with 310hp and 325tq from factory. Also has LS6 heads. Swap out the intake manifold for one from an LS1, LS2 or LS6, fit a Z06 cam and springs, and you've got yourself a nice setup.

Do you make motor mounts for the LT1? I have been looking at the 5.3l LS motor just because its really cheap compared to a 5.7 which I would like to have just 300 hp for a while becuase this is a 924S so rubber is limited.

What I said was "There seems to be some junkyard dogs, and some really nice conversions that cost $15k-$25k." Naturally there will be some in the middle as well.

Anyway if your time is free, you are a good scrounge, and you can weld and fab you could probably build really nice conversion for under $10k but as they say in the weight loss commercials, "results not typical." Those people could also probably cut the front off the car and put on a tube chassis if they felt like it.

Default Lowlife?

No, you are just well informed. The plate I designed was actually mic'd and dial indicated from 4 different C5 torque tubes and the RH plate was off concentrically and burning pilot bearings and torque tube shafts and TT bearings.....

I have a quick general question for those with a good LSx engine swap.

I have a 951 and what I like most about it is highway passing ability. 60-90+ is just such a sweet spot for the car.

The V8 swaps are great for low end, obviously, but I'm wondering how they feel at higher speeds on the highway? And you've still got the HP to get up at 160+ mph, right?

Sorry for the ignorance, I've never even been in a fast V8 like a Corvette. The phrase "running out of steam" is sort of the impression I've gotten about torque-y V8s, though I'm sure it's way off base.

If you haven't driven one, the best way to describe it is, there isn't a spot that isn't sweet. A 100 MPH roll on will leave your tummy in the spare tire well.
