CAD models for the Porsche G50 are on grabcad if you want to mock up digitally, although I know that's not your style

FWIW, the 01+ Tips from the 996 are CANBUS and much stronger, like the NAG1. The '99-00 are much simpler but can only handle 350ish HP. I haven't actually seen any failures and know of 1 guy running one behind his LS. He didn't have any issues. I thought about using mine but I wanted another manual sports car so I'm swapping to the 6MT.

Surprised no ones pointed out the obvious yet, CUMMINS!
Roll coal, unlimited torques and make all the mpgs at the same time!
Someone mentioned needing some weight too.

The Corvair engine is reliable enough and can be upgraded to about 200 HP or so..Over that overwhelms the suspension and for sure the stock brakes...

|Beat95YJ||Will the LS bolt to the 4t80, or custom adapter?|

|Realsquash||I'm sure you could figure out a way to make the car hinge in the middle to get to the engine. You are very crafty with the sheet metal.|

^ haven't ruled anything out. The Northstar is about the same weight and power as a LS4 though it is a bigger package.
One drawback of mid engine r&r is that it has to come out the bottom of the car.
|09-15-2019 08:04 PM|
you don't fix the motor, you throw it away when it puts parts out
|09-15-2019 07:49 PM|
The Northstar has fallen out of favor over the years. It is a perfect example of an engine that was slightly over-engineered for its own good. It's finicky, high-maintenance and expensive to repair if anything breaks.
It is convenient that the 4t80 comes with a Northstar though.
Maybe a 5.3 ls4 with a *small turbo. 600 hp with an auto that could handle it.

|bdkw1||LS is narrower across the heads than a northstar. Should be an easy fit.|
|09-15-2019 05:17 PM|
actually, on second thought, probably more commonplace than LS4s making big power with the bottleneck of the trans taken into account
oh and the car you buy to get the better 4t80 comes with the all-loominum northstar already
|09-15-2019 05:03 PM|
Porsche transaxle and turbo LS would be sweet, but the impala setup really seems like the way to go for what your looking to do with it.
|09-15-2019 03:50 PM|
|Realsquash||Northstar is more interesting than an LS swap and I think they are decent engines. I don't think you're going to turbo it to a zillion HP, but this car is a roller skate already.|

Here's a Corvair with a 4T80 and a Northstar.
Can't find any pics of an example with a 4T80 and a 5.3 LS4.
|09-15-2019 01:54 PM|
|65Chevy4x4||Yes do it|
|09-15-2019 01:11 PM|
|JR||How it sits in relation to the rear axle (LS4 in place of the Northstar).|
|09-15-2019 01:03 PM|
Thinking about a LS4 out of a 2005-2009 Impala SS FWD.
They originally came with a 4t65e transverse transaxle but a better choice would be to modify and use 4t80.
It's an oddball set-up but would put the Gen IV motor just in front of the rear axle, have a stout 4 sp auto and relativity speaking would be dirt cheap to do. A few bolt on mods bring it to 400 hp. Not enough, add a turbo.
The 4t80 came behind Northstars, but I'm not interested in that motor.
