hey bro do you know how much difference does the 275 cam makes from the stock cam.

Depends man.  Intake duration can be 275 but exhaust can be completely different. same goes with lift. 

275/275 is mild. can be run on EFI apparently.    But It's useless without raise in compression. You'll probably lose low end torque with the stock head/block combo.

I can never get enough of this combustion chamber.....    Just beautiful. 



High quench MN47 head.

Hello Ryoskatekov!  I have an 83 ZX as well and I too have a set of 72 240z SU carbs.  I added you as a friend.  I currently have a built N42 head, with a stage 2 grind, MSA 6 to 2 header, and the twin carbs.  I've been reading and studying your pics, but would love to get some more info, as I'm going to attempt to at least get everything installed this weekend?  Still gotta order a few more things before she'll be running.  Thanks, Jason

What spoiler is this.

 Allright, It's been a year since I last posted my early mischief. I honestly can't believe the amount of stupid shit I made you guys go through. But we all gotta learn somewhere...

 I've had a few people ask me about the setup so I figured I might as well just post all the things that's been changed so no one tries some redicule shit like 38mm carbs on L28 and expect results. 

So I'm not sure if I posted, but the 38mm experiment was a disaster mainly because of the combination of utter shit parts choice. I ran it with the Z-N47 head that had voids, leaked coolant into oil, 38mm had leaks in the throttle shaft just like the 46. And the distributer was a E-12-9x running on fake signals which I doubt was on the right timing.  Oh and I had an exhaust leak. 

So after that happened, I re-did the whole damn thing over realising that I've made a huge mistake. 
-Z-N47 head was replaced by Maxima N47 in the picture a few comments above, 
-Flushed the engine with cheap oil. Despite the coolant-oil mix incident, the motor is now at 220k miles and has 200psi on all cylinders.
-274/274 Schneider billet cam.
-O-ring'd the 46mm and made Viton gaskets so the damn'd spacers won't leak. 
-6-2-1 Headers and a straight pipe. 
-Put on a nice and reliable stock airbox. 








I have the airbox on with the filter.  I think I took the photo because I was adjusting it or something.   The domes are from the 38s since the pistons fell at better timings than the one that came with the 46s. 

As for the looks, I scored this rare - discontinued MSA? Classic with brake ducts. 


I rolled with this look for a while... 



But then everything just went down hill from there.... 

Remember this pos? 



Well, It broke loose and came back out from the attic. 



Stanced. Perfect fitment. 10/10. Wow. 

 

 

 

 

I quit the shitty part time at the rink so I doubt I'll be frequent again. But whatevz. 

 

 

 

 

oh, and I've been experimenting with Z31 seats.

Oh, and a shitty camera phone vid from while ago.
