No not at all, as If your were to build an all motor @ like 12 to 1 cr on a 4.5l i feel you would be around 400 whp and prolly 300 tq. Which it a very very fast car. Yes larger injectors will be need as with exhust.

This stroker kit is on my grocery list...

Sh!t, that sounds soo awesome. I know an N/A stroker Z motor isn't the "best" bang for your buck for making power, but there's just something really cool about staying n/a and doing something that radical.

follow up ? for jnaut, would 12 to 1 cr be run on pump gas 93 octane?

Will have to remember this when I get my GTM 4 stage next year

Yes, I feel it would be with the dynamic timing in our ecu. Yes u r correct... being able to say "yea its n/a, making that power." What else is awesome, if u have a warranty issue as lone as its not the engine itself, they would never know. U can't see in the engine hahaha score for the consumer

Shoot, if 12 to 1 is acheivable and safe w/pump gas, a 4.5l stoker that could rev safely to 8K would be sick! Honestly, if it could for sure make 400whp or so with 300wtq, I think I'd def go this route over a TT setup. It'd be perfect for track days since the excessive heat generated by a TT setup wouldn't be an issue.

Yes, i totally agree for track set-up. Less chance of issues, plus exiting a corner is more consistent. I keep you in the loop, as I have a customer contemplating the idea of a stroker kit in his 370z.

Hey Jason look at the piston & rod kits, is that everything I would need?

From whats in the picture , what else you need you will get from nissan.

NewYorkJon34 · 05-22-2011, 09:42 AM

What else would I need? I could search and see if GTM sells it

jnaut · 05-22-2011, 09:58 AM

nope, nissan only. unless u want head studs.

NewYorkJon34 · 05-24-2011, 11:01 PM

Hey Jason, Rods & Pistons? or stroker kit?

oleg · 05-24-2011, 11:33 PM

in for more info, this is really sweet if 400hp is potentially possible on n/a

I dont think yall understand that these bad boys have been out for more than a year and Sam is the only guy in the world with pistons and rods for a 370z. Got to love how GTM is mostly exclusive to Nissan and does not set his focus on a ton of different manufactures of vehicle. This keeps us 370/nissan guys with a plethora of fresh product. Some companies want to sell it all and leaves the choices limited. Im pretty sure if you could convince Sam that adding a shark fin and laser beam to roof of the Z made nice power gains, he would produce them for us all

Brazilbro · 05-25-2011, 12:00 AM

I liked the same thing about AMS when I had an EVO. I like it when a company focuses on one thing and does it right!
