not direct fit on the 370z, you need either an adaptor or a whole new intake manifold.
couple years ago I did that adaptor and you can see how much bigger the maxima 09 TB is.

the oem intake manifold inlet are about 63-64mm and could be bored a bit bigger but there isnt much meat around and its in plastic.

You will be require re-pin the driver plug for the TB.

I wanted to bore out the stock ones but I think I read somewhere that most go is like 68mm but I could be wrong. But for the money someone could get two maxima TB. I already have the upper plenum ported. How much did you spend on the adaptors? And what do you mean by a re-pin? Thanks for the pictures and info

that 68mm is the outside mesurement pretty much on the intake manifold inlet.
I wouldnt go more than 65mm....
keep it mind, its plastic.

I spend 10$ on the 2 adapter that I machined at work and a couple hours.

The 370z as you know has 2 TB and they arent interchangeable.
the plug arent pinned the same from both side.

Like I said if I remember correctly its the driver side that need to be re-pinned like the passenger side.

that was my secret mod at the time just before I blew the VVEL and then well it was put on hold. Never tried the setup.

Also make sure the oil passages in the crank are designed for higher rpms. I have seen the GTM ones in person and the method they used was the most direct at higher rpms.

Yes, he could have easily hit 400whp. The only thing he didn't do was get into the heads. He had a stage 0 long block which meant he only had upgraded rods and Pistons...

Elmo370z · 12-26-2014, 09:47 PM

Damn wish he had more funds to complete the project.

bullitt5897 · 12-27-2014, 11:16 PM

It's not that scary if you have a competent shop. That has been the number one issue with this mod. Most that are installing the cams are not installing them properly and are not following the service manual instructions... 1slow370z installed his himself...

Elmo370z · 12-28-2014, 12:33 AM

My main question with these cams, will they be ok with the stock manifold.

Elmo370z · 12-28-2014, 06:58 PM

Yes, its 62mm right? I want someone to make a intake manifold

Zoren 370 · 12-28-2014, 07:22 PM

Synolimit does boring and polishing of intake manifold.

Not really sure of the size of the Z1 TB but it looks like they just made the butterfly bigger.

bullitt5897 · 12-28-2014, 07:48 PM

The maxima throttle bodies will only be beneficial on a custom intake like the GTM built one for 1slow370.

Didn't see this posted. Pretty much answered what I needed to know. Thanks

Elmo370z · 01-15-2015, 07:53 AM

what are your thoughts on increasing the bore and shorting the stroke? I'll have a spare motor soon.

What is the objective .... not sure what benefit you are chasing.

Elmo370z · 01-15-2015, 10:37 PM

I want a mean NA motor. Just toying with the idea, I know that alot of exotic cars make big power with larger bore and shorten strokes without the aid of forced induction.Is it feasible with out motors?

1slow370 · 01-19-2015, 07:02 PM

Look at our bore/stroke, do you really need to go more oversquare? Just get stronger lighter internals and better oiling . Then change everything else
