Just skimmed through his build good lord.....I wonder how much he spent on it. But yeah I guess it does make sense that the engine is already an efficient engine stock. Funny thing is, I've never once seen vq37hr advertised as a good engine. It's always 2jz, ls1, k20, n54, etc etc...

If my budget was limited, I would probably just stick to testpipes/catback and intake - or save the cash for a used stillen SC or something. Seems they go up for sale all the time and you could be modestly supercharged for 4-5k, with a path forward (air-to-air intercooling, fuelling upgrades) for more if you wanted in the future. I have also seen used BP kits go up for sale in the 5k range.

How reliable is a Stillen SC? Last time I looked into their SC's they were giving people issues.

Generally no, can't mix full cbe with a different axel back. If it were me and cost effency wasn't an issue and I wanted the most NA HP I would do:
Stillen G3 CAI
Z1 manifold
FI LTH
AAM 2.5Mid pipe
AAM Resonated Short Tails
Ecutek Tune

So, LTH....Has anyone here posted numbers on LTH vs TP+Z1 headers?
