How to make '00 VI work with 3.5?
I want a full 3.5 with a '00 VI, '00 Fuel Injectors, and Fuel Rail, full VI lower and upper IM. How would you make this work with a full 3.5 heads, and bottem end???

Keep the better designed aluminum manifold.

I thought Tilley was keeping his 02 IM?
BTW, the 00VI has yet to be dynoed on 3.5 heads, so we don't know yet. Tilley dynoed 226whp/205wtq with the 00VI, 3.0 heads and 11.5:1 comp. Then he dynoed 233whp/230wtq with the full 3.5 (better heads and all, but 1.2:1 lower comp). He opened a valve on the 3.5 and dynoed 238whp/223wtq.
Also one of the reason his top end isn't good, I think, is because he doesn't have the 3.5 ECU. Stock VQ35 cams stay a 240 degree lift all the time if they don't vary (in Tilley's case, they don't). But when you have the VTC with the 3.5 ECU, they vary from 205 degrees to 275 degrees. My guess is that this is to get the best of both worlds.
Also, he has a light flywheel, UDP, full exhaust system (with headers) and bypassed AC/PS, so I think he would dyno more, both peak and along the RPM range with the 3.5 ecu.

I would say with the 3.5 max IM nissan was trying hard to have low and mid range ...but with SR design he shifted that but...i cant go to wally world and buy his IM .Can you?? He has good hp but peak is nothing special.
If the max 3.5 IM was so good how come nissan doesnt use it on the sports car 350z?? Because stock for stock the 350z IM is better . My point is its prob not the best IM for the powerband im looking for.
I'am just testing the dek on the 3.5 if its no good for me ill try another IM...obi wan there is another

He has UPD, headers, exhaust system, lightweight aluminum flywheel... I was expecting something in the 240's.
Also, those are peak numbers. He hasn't posted his graph. No doubt his car must pull real hard, but it'd be interesting to compare graphs.
