VQ35DE vs. VQ37?
I have heard that the 35's did not really like boost, and the bottom-end was weak. Is the new 3.7 stronger? Are these TT kits "running on the edge" of what the engine can handle at 450whp, or is this a safe level of power for DD'ing the car at on 91* pump gas?
I read the FAQ, but it seemed a bit dated... |

on a DE engine? better turn that boost down a few bud, that bad boys gonna pop soon. I believe the recommended boost pressure on the APS kit was 7 lbs for a grand total of 350-400whp, which APS deemed as "Safe".

IIRC, Sharif had his '03 350Z boosted around 450whp+ with stock internals and never had issues.
350Z_2nr, is yours daily driven as well? How many miles have you put on it since you had the APS kit?

Like any engine, definition of safe will vary from engine to engine.
From a few 350z I know many guys are running just below 450rwhp and have been for upwards up 30,000 miles or more, with little to no issues (just normal maintenance). Though there are guys who try to run the same thing and run into issues, it comes down to prep, good shop (or install really), and taking care of the car properly. I would not say the 3.7l is any better or worse, but experience of the past has given a lot of what can/cannot be done to the current engine (3.7l).
