Yep. Got some things in the works for spring.

LMAO, if you don't know the history on this build or the person that is responsible for it, you are sadly mistaken. If it gonna get done this build has a better chance than any so far.

Someone just rebuilt an NA engine to 13:1 and did 403hp on E75. Of coarse it had supporting mods. Still haven't figured out why he didn't upgrade the exhaust cams. It was on SOHO's Instagram.

The car on Soho's page had C2 cams... stock headers though

EDIT: I was incorrect, the owner chimed in and actually has Z1 headers. Awesome build and results either way

And a stroker IIRC

Whjaxn17 · 11-05-2020, 11:44 AM

BC 92mm stroker crank

13:1

JWT C2 cams

Z1 headers

Z1 intakes with upgrade

OEM GTR injectors

and "all of the full bolt ons available from Z1" which I assume means ported upper and lower as well

403whp/314wtq on E75 - it was run out to ~8,100rpm on the dyno, but actually peaked right around 7,600rpm

That stroke motor power comes on sooner vs the stock compression motor. Very interesting too see the difference in power delivery. This Jun cams seem like they love the higher Rpms. Be interesting to see if 1slow were to rev out to 9k.

Best comparison we have for now

Elmo370z · 11-05-2020, 04:42 PM

The striker motor makes power earlier in the power band which is cool to see, 1 slow torque is further to the right. I’m impressed with both overall, I wonder if a good set of long tubes would make a huge difference in the mid range

Elmo370z · 11-05-2020, 09:43 PM

I knew this was possible with the right parts when I started this thread many years ago, stock intervals or built.

It nice to see the other 400+ graph was wondering what it looked like when Soho was talking about it and still pulling at 8500 is impressive. Mine starts to fall off at 8000 but 8300 she starts to drop hard so we set it to 8200. It was a long day and 25+ pulls he lifted early after peak on the last run/posted graph. I wish I had the ability to do writeups like Rusty and several others that make this forum great. But alas I tried and they turn into run on crap like this lol.
