Great idea for an IMS "blown" motor...even without the real high output motors, it would be a good solution...I would not mind a GM V8 in my 996...nice growl..
I "did" a Jag Chev some years back...350/350 4 bolt main with a 700r4 trans...very nice ( a lot easier with the JAG)

I beg to differ.

Everything has a finite life. I'm thinking my 115K mile motor is still worth around $4k? on a good day?

LS1 from a GTO i can pick up locally for around $1k.

Local guy does these swaps (Chavis Performance Engineering) and he quoted me well under $10K for the swap.

So lets say $10K - $4K... For around $6K out of pocket I get a motor that I can rebuild for considerably less than a 3.4 rebuild that'll have a couple more ponies.

I'm a purist at heart but my brain says that sometimes you have to cut the cord before its too late.

Tyler does good work and its really not a hard swap at all. I would even say its one of the easier swaps due to all the space thats available in the engine bay. No steering rack to clear, no crossmember, no firewall hacking...just drop it in and bolt it down. Depending on how integrated you wanna get with electronics, it can make the swap even easier (or harder). compared to the e36, I would say the 996 is the easier swap.

My car has cruise control but i'm not sure if I need it. I certainly dont "need" A/C but it is nice to have...

I've been passively looking for a motor but I think it would be wise to step up my efforts

The 996 is by far my favorite.
I emailed Andrew from Stuttgart muscle and he gave me $100 off the whole package I forgot to ask if the transaxle plate clears the sway par and cross member so I just emailed him to ask
i also spoke to Texas performance concepts and they said they don’t carry any kits for the 996 ls3 swap only for the older ones

So today I found a ls3 crate motor fresh built with comp cams diamond racing forged pistons arp bolts psi stand-alone with 411 ecu tunes by champion motors and tons more done to it for a great price
I’ll be going tmro to pick it up I’ll post some picks tmro
I’ll place my order with Stuttgart muscle tmro

anyone know if the renegade plate clears or that too needs to be modified?

Never mind Andrew just answered me so their new design does not touch the sway bar

I guess I’ll be placing my order now then Can’t wait!!

The one thing I'd be tempted to do is build a ls,, at 4.8L with really good spinning parts, so it could still scream like my 3.6..
Put kinsler electronic injection with stacks and use a old school 911 air filter setup.. something that redlines in the high 8's,,,
Basically a 305 sprint car engine..

Kinda of the point of a de-stroked ls3. Its a 4.8 crank and rods with custom but available pistons. Most say u r safe to 8k on hydrauic lifters. Im still specing out parts and buying slowly.

I bought my car as a roller but got the motor running for a few bucks so i have been enjoying it. I dont really have any history on the car other then it knowing the ims and a few things were done about 30k ago but with 200k on the clock im sure i will eventually blow it up.

I don't know about you guys but, I'd need A/C and functioning factory gauges to consider a LS swap.

I'm probably not doing a swap, but I was in Vegas in April and stopped in to see Renegade. They seem first rate. They spent a full hour showing me around and talking Porsche. I'm curious, why would you stay away from them?

I would love to see a post from someone who has successfully done it on a street car and registered it in a state that requires emissions inspection.

Anybody ever ran across a good how to make your Porshe piggyback a different engine ECU guide?

I suspect that a 996 is so CAN intensive for the gauges that your stuck if it has to look factory,

But one thing I read somewhere is the AC control on the 996 is actually fairly primitive.
Its not really integrated with the engine ECU stuff other than the wire to engage the compressor.
the dash module actually runs the thing for the most part, then there is the fan control module but that is
likely just a PWM for the fan speed driven by the dash unit,, the guy also said ther is a manual control that
we didn't see here in the us that just replaces the climate control in the dash...
