I'm betting it's a VK45 with some Zytek-style upgrades. The P2 class engines make near 600HP without restrictors, so yeah. :yum:

Did someone say Zytek? If I was made of money, I'd ask them for one of these, I bet it's a sweet engine for the Z: ZRS03 « Zytek Motorsport :) 275 lbs 3.4L V8, 530hp, 330ftlb tq, 9250 redline!

haha the FRRenault engine is cool... still rather have the VK45 though.

Whatever it is GTM is building, you can bet that it will be ridiculously costly.

hmm.. probably less costly than an LS engine/trans combo and all the associated extras to make them work in a Z

If at some point I say that my engine is blown or has a spun bearing or something, noone tell my wife otherwise!

I dunno man, these are the same guys that sell stroker VQ's for 24 grand.

You're gonna spend 5-7K on the LS and tranny, 500-1000 on a drive shaft and maybe 300-400 on motor mounts... a little on some gauges (can vary wildly depending on how cool you are) and after that it's all labor.

Labor is the expensive part.

Not when you do everything yourself. (Like me)

Comparing strokers to LS motors are a BIG difference. Strokers are very expensive for there not common for one thing. All the parts are custome made down to the block themselves. Not to mention the heads. There you have 10K+ in parts alone.

LS swap is not cheap either. I have several friends with kits. The motor/ tranny can be 9K-12K. Then custom driveshaft, harness, plus other odds and ends.

In the long run it's all costly. But more importantly is the direction you want to go. I feel the GTM V8 will be best bet. If you could find a blown VK for super cheap with the block in great condition would be your best bet. Avoid a lot of cost instead of buying a new bare long block for GTM. You wont catch me dead with anything other than a Nissan motor in my car.

Empty Nest Syndrome... Car is with the cage builder this week. :excited:

So I need to adjust my tune. Hoping to get an hour on the dyno when I go to pick up the car. I'm down about 20 HP from before I got the exhaust and changed filters.

The street logs I did showed me running pretty rich, as well as a rather alarming imbalance between right and left banks... There is some cylinder correction baked in to my tune, so I'm going to zero that out and see where we stand. That plus the engine speed calibration being off for my pulls (the dyno thought I was spinning to 9.2K RPM...) makes the graphs look truly depressing! I was able to do some conversions and plots using my old graphs as a benchmark... We should be talking about some serious power, assuming I can get the curves back to looking like they used to.

Here's hoping!

That was the price quoted to me by courtesy parts Nissan. It is possible that they gave me the wrong price so who knows, I gave them the part number night out of the nismo catalog.

if you end up ordering it and it happen its the right one . don't say anything online ! and let me know ;) I will order 2 ! hehe

Okay I will order it and see what I get, it sounds like the right one - we shall see!

Well, end of week 1 of cage build (was only supposed to take a week) and as of this morning, he says he's waiting on material and the dies for the bender to come in...

Well, ****.

So I guess we're waiting another week...or two... :-/
