Default High Compression EZ30r - NA -

Just been thinking about this idea I have. Has anyone done an all out NA build on an EZ30r? Say individual throttle bodies, larger cams, lightweight 14 to 1 pistons, proper headers with burns style collectors etc..


I am considering building this exact setup for the new time attack car. What about the 3.6 crank... anyone know if that crank will fit the EZ30r or would it just be better to run the EZ36r.

Does anyone think that 450whp would be achievable? And whats the complete longblock weight of the EZ30r?


Thanks guys,

Doug

3.6 crank won't fit without using a drysump, there is no way to drive the factory oil pump on it.

450whp NA...NO

But you should buy mine anyway.

Ill trade you for the Red shell and a Front Diff

I was thinking along the same line for a tight road course car after the current projects.
3.0 crank in a 3.6 for the rpm with high compression NA should give the Rotary geeks a run for their money.

i think those are some pretty high numbers to ask for from a all motor 6 cylinder.

only real way to get that type of usuable power in NA form is to go V8... i'm actually doing a high compression stroker build to my mustang hoping for a 10 second pass in the late summer

IIRC the ez36 (needs drysump as explained above) will still only make it a 3.2L...
also a very short rod ratio so some argressive cams will be needed to help shift the torque curve some to help reach the HP wanted, if possible....you'll be spinning really high to get that power or have to be ultra efficient. IIRC bigtime 350Z builds are in the 400-450whp range.

Think of cosworth at the shootout and that new TA team from CA that's making 450whp in their setup and the Z guys are blown away. I'm pretty sure that's a stroker VQ as well.

that's about right, I think Cosworth made around 420 with theirs in the shootout, no?
