4.1 stroker? Who's done it? Pros vs cons
#171
#172
I have build a 3.8 motor with Nissan GTR conrods and pistons. It eliminates the weaknesses of the 3.8 namely conrods and piston blowby (oil consumption). I have lowered the compression to 9.0 to 1 as I am running a RIPP on a ultra high altitude pulley. Pulley was homemade. The motor have been balanced internally as well. I did not go for the stroker option as it is already a bored out 3.3.
The advantage of the GTR conrods is that I have used the standard ones which the performance guys discards to fit high performance ones. The crank needed severe cutting on the big-ends which meant that I had to have everything balanced and the crank nitrided.
I am just strugging with some wiring issues as I have also changed it to a stick shift at the same time.

I'm currently running a stock 3.8 with stage 2 ripp supercharger @ 10 psi. Ripp long tube headders, 37" tires ats Trans. With cooler and torque converter 5.38 gears throttle body spacer screaming demon coil pack, 6" long arm lift. And $1,000s in extras. Currently getting 249 whp@380 torque. The #s you put out jerod5 isn't quite what I was expecting running 35"s. Are you using stock gears and did you get a dino pass before motor swap to see the difference between stock 3
