I daresay, that some of you are quite generous in suggesting the prices you have! I would like to offer these units at or around the price-point of the types of engines being used in various vehicles. For example, for use behind an LS7, or built LS3, I would like to have a suitable transaxle for around $15,000...about the same price as the engine. I don't mean a marginal unit either, but a transaxle fully capable of handling the...

Bill - I would happy to discuss this with anyone, I understand where your friend is coming from I believe, but that might have been a misunderstanding of what I was trying to get across, I am not sure. Still all and all I do not profess to the end all authority on any subject, and I would be happy to continue discussion on this or anything else. Thanks for the post.

I should also add that there is a 924 turbo with a highly modified Grand National engine (3.8L v6 turbocharged) and a 944 with an LS1 with a Magnison supercharger both with over 550 ft lbs of torque at the rear wheels using this transaxle without any issues. The LS1 car is raced at the drag strip often as well. The guy with the 924 destroyed a few 944 016 transaxles before he got the 951 (944 turbo) transaxle.

Howard has a good point. $20K baseline is not unreasonable, perhaps a tad low by the time it's all said and done. I am an exception only because I had a lot of "free" assistance. 430HP LS1 with a 930 LSD gearbox for less than $15K. This includes modified front dress, oil cooler, filter & pump for the gearbox and milled bracket & slave cylinder for the clutch. An oil cooler for the engine and all associated...

Here is a interesting website. Good pictures of internals of a Renault R21 and information on upgrade parts along with link to D bells webpage. P.U.K. Esprit Racing No personal interest here.

Guys, I am sure most of you know the attached documents already, but just in case some of you do not....
