So I知 planning on building my motor first before I think of FI. What would be the best route to go im already at simple bolt ons with a bigger throttle body and ported upper and lower intake manifold with e85. I was thinking on boreing it and stroking it to 4.15L, head studs and cams. I知 not sure where to start I知 coming From LS platforms so this is a little new to me. I知 not sure of all stuff to be worried about. Basically the plan is to have it be able to reliably handle 6-800whp reliably and daily drive it.

 

Since you didn't say AWD, know that Infiniti did not offer LSD in the Q40. So if you expect to boost this sedan over 600hp some day, then maybe you should look to your rear end first.

 

it is a Rwd I have upgraded the rear a bit lot alot I forgot to add I already did a vr30 tranny with level ten torque converter custom drive shaft, braced and Z1 diff with all new bushings. I was looking at new suspension like SLP or something. Basically trying to redo close to all of it built up. I had a built 06 GTO I had built before It caught fire so sold the saved parts and got this to build as another fast daily.
