Performance upgrades
so im trying to debate on swapping a 3.5 with 6spd tranny in my 4th gen since there more aftermarket support (but heard it a pain in the A$$ and cant find a full write up ion how to do the full swap) or keep my 3.0 and build that?
but havent found much of a support in finding aftermarket upgrades, please help want to make reliable 450whp
also have to replace flywheel due to 1336 code chipped flywheel
so if 3.5 swap is better rather wait and do that then spend the money on another clutch and flywheel
PLEASE HELP!!!!

I know akeems maxima from Canada (street outlawz) is 350+ whp on stock 3.0 with 00vi and supercharged at 12 psi. You can use 3.5 heads on a 3.0 to have lower compression and boost a lil more
Your best engine options are:
VQ30 with 00vi
VQ35 with VQ30 timing
Get headers
TUNE!!!
I wouldn't bother with a 6 spd either.
As for your CEL code, the flywheel has a timing ring on it. The flywheel is probably fine.

I have a full 3.5 swap ready to go, just no time for it 
hopefully spring break.. and yeah 450hp needs some rethinking.. for street use and street "applications" you should stick to a lower number...

There is really no point in building a VQ. Stock motors with the right bolt ons make plenty of power to destroy transmissions or drive shafts. FWD cars don't make the best of high horsepower. 300 FWHP is more than enough.

VQ30 with 00vi

300whp would be nice as well just cant find a supercharger for it ive been looking

3.5 matted to a 5spd tranny is veddy naice... dis what my max has... if you want 300 whp there are ways to get it without fi... but the amount of money you would spend on cams, pistons, itbs, e85 conversion...etc... you could just buy a supercharger and get there cheaper...

Doing the full 5th gen OOVI swap (injectors, LIM, fuel rail, 5th gen TB or Pathfinder TB, and 4th gen IACV). Or you can do what I'm doing and get a full DEK swap for pretty cheap. Then sell parts off your DE motor or sell the DE all together.
Ok, here we go.
1: Its not a honda, you cannot just go full wiring harness, ecu, gauge cluster swap, it doesn't work, I personally spent over 4k trying to make it happen, it can't unless you are a wiring genious.
So our option is to do a hybrid swap, where we "trick" the car into thinking there is nothing different with the engine, this is accomplished by leaving all the timing components (read: the stuff that makes the engine run) and adapting them to the 3.5 block. There is a guy on here who makes the adapters, you can also get them from JWT.
Basically you take out the 3.0 block leave the oil pans/timing in tact, apply the timing chain adapters, which require intimate knowledge of the timing chain system, then install the 3.5 block. With this done your car's ecu will not think that anything is different since all its sensors (for the most part) are still reading everything just fine. You can delete the vias, and the egr with block off plates from NWP, and get some spacers from them while you are at it to bump the hp of the 3.5 up quite a bit.
VQ35 engines have variable cam timing. The 4th gen has no way of controlling this.
It is far easier, and cheaper, to swap the timing components than it is to do a full ECU swap. NATS for instance, its a *****.
Can you get a full running 3.5 into a 4th gen? Yes. If you are asking if it can be done, then you most likely do not have the means to get it done.

it amazes me how people wanna do big jobs on their car but are too lazy to research or read. I was the only guy in jacksonville man enough to take on a two 4g63 swaps in a mirage because I read and did my research while the majority of people paid to have a shop do a basic b18 swap in a civic.
