THANKS FOR THE INfO!!!!!!!
not sure if you know about my setup. but im running HR HEADS on a DE BLOCK.
its called 09 Maxima motor. Its possible for RWD too.
checkout my website and stuff for info.
Im running a STOCK 09 maxima motor putting down 301whp 277tq
edit, ive always wondered why you never switched over to the HR moto for your race car.

Yeah i posted it a long time ago.

I think i originally had it in N/A builds but it got moved.
Ive got insane good ideas for the Z platform but i don't have a Z lol.

Who is taunting??? This topic of "shortdeck" block with HR heads has been thrown around over and over and over... Even the "Team USA", ARK R32 build using an HR block with CNC ported Rev-up heads has been discussed... I am just saying that Nissan builds this "mystical" shortdeck HR already... but why do it? The build requires an HR harness or custom harness plus the cost of an engine build with the correct timing covers, chains and timing components. The alternative is just do a full HR that is sourced from where ever with harness, ECM and transmission, about $4000 or less, plus install. Now as for the "proprietary" information... anyone that looks outside of nissan to see where the VQs are placed will find where the shortdeck HR is.

A FWD 09 maxima timing cover would work on a RWD block? Would a revup need a harness swap since it already has VTC on both sides of the bumpsticks? I'm guessing a connector or two may differ but that shouldn't be that much of an issue if that's all it is. An 09 maxima LIM would obviously be needed... I'm taking a stab in the dark here but the upper intake manifold may swap over from the RWD VQ HR's.
edit: Nevermind, forgot that the upper IM for RWD HR's use rectangular ports.

This! Ive got a set of HR heads, that im planning to port and do cams, for my 09VQ motor.
The swap from adding EVT on a older ecu car, the issue woudl be a system to run EVT. Haltech works good. On my setup Haltech is fully running my EVT system.
Maybe we should make a new thread.

this, porting is going to cost you velocity which kills low end and mid range, nothing on the street will benefit from ported hr heads especially when most people are scared to rev past 8k because of oil pumps. unless the ports are cnc machined from CFD software designs you actually risk hurting the flow on something that flows so well for its size already.
