I've done some research and recently a deal came along for a LSD that comes with a 3.9 FD. I've been toying around with the idea of going FI. My initial plan is stay NA for a high rev monster. Anyways just seeing what you FI cats think about going FI with a 3.9FD. Would you go SC or Turbo and why?

If i went SC route with 3.9FD, can i replicate the torque feel of a turbo car? My goal is not to have a dyno queen. A nice 400hp and near 400tq is enough for me. I find 400hp is probably near max one should have for daily city driving with a mixture of freeway too.

 

I have 3.9 gears, Tilton Rally clutch and Turbonetics ST kit...

Im nuts tho...

Normal driving is fine, I burn tires ever 3K..

1st gear is a litte tricky..all others great..

How much is this LSD package??

If your thinking of doing FI soon and dont plan to track race I would forget the LSD combo for now and use the money for FI..I dont have a upgraded LSD and do well on street...

Im thinking this package LSD thing if a known name is about 1500-2000 right?? thats a nice chunk for a turbo kit...

If I did this all over again I would have just got a upgraded LSD vs 3.9 gears

 

I think the LSD helps tremendously for traction IMO

I had the full NA setup - tilton clutch, UR pulley, 3.9 final drive, JWT cams, crawford package, etc etc and a nismo LSD and 295 michellin PS2 tires and had more than 100% traction.

Other people ran just intake, tilton, UR pulley, 3.9 final drive, HF cats, exhaust with toyo 295 tires and no LSD and would always say they don't have enough traction. One guy said that he didn't think 295's were wide enough to get enough traction. Now maybe that's just tire choice, but I noticed that having the LSD the car stopped fishtailing like crazy and instead of having to try to control it to go straight, it just simply went straight where you had the wheels pointing

I returned your PM about my vortech and 3.9 setup. It works pretty well I think
