This project is taking longer than I thought, thanks to climate and my aversion to crawling around on a cold floor. however that being said. The vision is taking shape and I've sent the LS1 motor off for some work including mild porting and rods and pistons along with a cam and springs. The heads and cam are ZO6. The brakes are 02 tt 996 and i have a 030 front sway. The reason for this post is ask for opinions on springs and shocks for the beast. It is a road car but definately not a dd. Most likely it will be tracked and with a bit of luck spank a few vettes and 911s. Definately an outlaw though as i'm led to believe PCA won't want it around their events.

Don't know much about spring compression forces or suspension types for 968, but obviously it will have to compensate for any mass change/distribution..ride height, etc...



I was over at the 928leathershop the other day admiring a 928 lt1 conversion...I was surprised how well everything fit.



Have you posted pics here? (search never works for me more than once per log in...)

I wish I had pics. The car is still in storage and the motor is getting worked over. It started as an economical performance car but as everyone knows there is no such thing as cheap Porsche. At this point I've decided to go for the ultimate street monster. BBS 10" x 16 rears.

I've seen a couple of other 944/968 V8 conversions and they were truly a sight to behold. I'm impressed with the quality of workmanship most of these guys put into their Frankencars.



I'd really like to go with a turbo conversion with the stock motor and push 300 PS but it looks like for the same $$$, a person could build a medium/high performance aluminum Chevy V8 that would easily produce 400 PS.



If my stock motor ever goes flat line, I do believe a V8 might just take its place. I'm VERY interested in following these conversions and listening to what kind of experiences you all had as you went along. Seems like a slightly massaged aluminum Chevy V8 would be a no brainer for a replacement motor. But that's just me talking. Parts are cheap as crap and readily available.



Don't get me wrong, I'd love to see a Porsche 5.0 sitting between the shock towers but the cost to purchase and modify one to make the same power as a Chevy looks to be prohibitive.



You've got my attention, that's for sure!

Being located a few miles from Detroit, if my 4 banger dies, I would consider v8 power....inexpensive(per ft pound), strong, easy to get a hold of, and plenty of tuner shops in the area....

not a simple question - much of that is subjective and use specific - but to start:



corner weigh the car with the engine and all of its accessories and such installed (including chassis stiffening) - then you will have a front to rear bias and new numbers from which you can determine a multiplication factor for spring rate



then, go for a ride in a 4 cylinder 968 with a suspension you like



then crunch the numbers



then add 10-20% to those numbers to accommodate torque shift



that would be a good start

Woodie, give Scott Mann a call or email at Renegade Hybrids.com. He was out here conducting a PCA Driving Instructor Certification class recently for PCA (Pete Trempler could not make the trip) and we discussed the LS1 968 conversions that his shop has done in Las Vegas, Nevada. Scott will be able to make some recommendations based on experience. He has a 968 conversion underway in his shop right now. Good luck, Bob Blackwell. (just waiting for my four cylinder to need a complete overhaul and the V8 will replace it).

Great advice. My thoughts were toward Flash's suggestion and get the thing on the road and do the assessment from there.

In my coversion, Im using 300 lb/in springs front and 28mm torsion bars rear. I was using Leda shocks valved for the regular 951 and the handling was very neutral. The weight balance between the 951 and the conversion is very close to the same. If you are going to track it, maybe your springs and dampers have to be stiffer.
