Project 914n6 -> the infamous Nissan V6 swap, new motor buildup Options

[Chris914n6]

Logic, according to my brain...

In 2000 I installed a Nissan VQ30, 3.0L from a 97 Maxima. 190hp 205tq and it was great. Then things happened (rusted battery tray). Then it sat for a decade (recession). The engine now overheats the cooling system like a bad head gasket. Likely from aluminum erosion from sitting too long (other signs). Fixing that requires complete disassembly down to a short block.

Soooo....

I decided to move up to a VQ35, 03 Maxima 3.5L +80hp!!! (that's 42% more)

Here's the rub. To get the VQ30 to fit I moved everything forward 1.5". Renegade sbc trans blocks, shortened shift rod, small hole in the truck. To fit the VQ35 as-is I would need to move it back, likely to stock location, to clear the variable cam timing stuff. That means a new cross mount, new shift rod, redo exhaust, plus new harness and ms3pro ecu ($$$$).

Turns out the gearheads at Maxima.org like to upgrade too. They created a VQ30/35 hybrid. It's a VQ35 engine with VQ30 ecu, harness, timing components and accessories. I lose the variable cam timing but I get to reuse all my custom swap bits, which saves a bunch of time I don't have before RRC22. But it requires some new custom parts.

If one or more of our great fabricators has time and tools I'd love to toss email money your way. @mueller @tygaboy @mb911

First is the Throttle Body adapter. Replacing the factory e-gas with cable. I currenly have this partially drawn in CorelDraw and design is not absolute (still searching hardware). 96mm x 99mm. TB (red) bolts to piece_1 (blue) which bolts to piece_2 (green) which bolts to IM (yellow).

Second is cam gear adapters/spacers in steel. I need 2 @ 178* and 2 @ 180*. 4 total cuz 4 cams of fury. 6mm dowel pins look to be readily available.

Third is a pair of aluminum block-off plates for the VVT cam adjusters. 1.5" x 3.5" Also drawn in CorelDraw, which can be exported as .ai or .dxf. Actually I might make these by hand.

Been there with the back issues. I just had a injection 2 weeks ago that made my L5 issues worse!! I am pressing on regardless. The Boxster transaxle is turning out to be quite challenging. Do what you can. Take care of the back.
