That's another idea, they're the same right? With the exception that it's cable clutch.

And they're available.

Downsides to a cable clutch setup? Periodic adjustment required, so check it at oil or belt changes...?

You can still get new ones at the corner store...and the pedals will bolt in

and the mechanism...

would be nice if Integrated Engineering did a "reverse" intake manifold...

So I'm guessing LSD isn't a must with this swap as it is with a LSx engine, am I correct thinking this? I was pretty set on a v8 but now I'm not so sure. This is definitely very interesting to me... Will be watching this build closely. Also not sure if u already said what turbo are u gonna use exactly. Is it the C2 kit for the 07k? If not any idea which one? Thanks and good luck

I'd say LSD is a must...I'd even say it's a must with the stock 951 engine. I've got a S2 LSD trans that I'll be running. The shorter ratios should help with the higher revs.

Turbo isn't decided yet, I'll have to decide on my power goals. I won't be using the C2 kit, it'll most likely be a custom tubular manifold from Iroz. Turbo most likely will be 35r sized similar to the UrQ setup for around 600whp if I do E85/race gas. Pump gas will probably limit me to 500whp. My 968 is going to be a street-legal track car that's completely gutted (including lots of undercoating) so probably to the tune of 2500-2600 lbs. So 500+whp should be a riot. Even if I do a 35r on the stock internals and limit it to 400whp.

Eh, it'll be about the same price for a sheet metal intake that's built to fit.

As mentioned LSD is a must if you're going turbo, but if you stay with normally aspirated then you could have 200whp and get away without LSD. I've got an S2 so the higher rev capacity of the 07K is an advantage compared to an LS1 - which really needs a 951 or 968 box. Other advantage is no need to modify the brake booster/master cylinder.
Most other things need the same amount of work. No disrespect to the LS1 people, but the 07K meets my needs better.

Cheers,
Mike

I see... I figured the torque being lower with this engine, the none LSD 951 tranny would hold up. Can't wait to see this happen, very exciting.

LS1 engines are actually getting passed over with all the GenIV LS2s, 3s and L99s now becoming available for not too much money...
it also seems like there's not as many LS1s available for sale as there were a few years ago.

then there are lots of engines getting built that can rev pretty high...

with the right cam set up, my 388 c.i. LS7 would be able to spin up to 7,800~8,000 safely.

Oooooooh, cool, LS1's are collectable? Speculator's paradise? Wonder how many I can buy with my bitcoins?

just kidding... got a lot of respect for the LS-powered crowd, I shelled out for Greg Sloane's book.

Cheers,
Mike

The non-LSD tranny will hold up, but your tyres won't...
