That is correct it did, and stock. The list I checked were for current production models, which in all honesty makes the F20 feat even more impressive.The highest current HP per Liter N/A engine is the Ferrari 458 Speciale of 132.7.

Regardless, rarefied air as far as N/A engines go.

Looking forward to seeing the results. Do you have an instagram to follow along on the build?

Sorry, I don't have an Instagram account. I plan to document with pictures and videos.

I know Dynosty put a little video together when they tuned my car last year because I think it was the first N/A Z they had tuned over 340whp. Hopefully the results warrant another video from them this time as well.

What’s 370 to the wheels? ~435 to the crank? I’d be happy too

1 x JWT C2 Exhaust Camshaft Set - 370Z / G37 (VQ37VHR) () = $749.00
1 x VQ35HR / VQ37VHR Timing Cover O-Ring and Seal Kit () = $120.00
Include All Extras
1 x OEM VQ35HR / VQ37VHR Water Pump (B1010-JK20A) = $67.00
1 x OEM VQ35HR / VQ37VHR Oil Pump (15010-JK20D) = $196.00
1 x Boundary Engineering HR / VHR Billet Oil Pump Gears () = $399.00
1 x Z1 VQ HR / VHR Oil Pan Spacer () = $135.50
Include Ultra Grey RTV
1 x MOTUL 8100 Oil Change Bundle - 5w30 () = $99.94
Additional Quarts 1 Quart
Filter Type NISMO Oil Filter

Starting the tear down this weekend. Hoping to have the car delivered to @Dynosty by the end of the month for a re-tune. In addition to the JWT C2 Cams, since laying down the 341whp/271whp I have added the following:

-Z1 Ported Lower Intake Manifold
-Z1 Race Intakes from standard Z1 Intakes
-Z1 2-piece lightweight rotors
-Dewla Intake Guide

Trying to keep my expectations in check, but would be really excited to eclipse the 370whp/290wtq marks. Would put the HP per Liter around the 118 mark in between the Audi R8 (117.3) and the Ferrari F12TDF (122.2) which are the pinnacle of N/A Engine benchmarks.

go E85 you'll see more power
not sure how many miles are on your car.. might want to look at doing the timing chain while you have the motor tore down

also just be aware you need to pull the transmission and the secondary oil pan to get to the oil pump out..

Thought hard about it but it just isn't that accessible where I live and didn't want to have to worry about it when I go an random drives/trips in the vehicle. Also, just want to see what the car will do on pump 93.

Why can't you do both? I've got a pump gas and an E85 map. I didn't spend big money for the flex fuel kit, so I do have to manually switch maps, but it's about as much trouble as setting cruise control. No reason not to if you're already in that deep. I got some GTR injectors for cheap and just had them put those in while my car in a state of shrapnel.

You make great points and I really have no argument against. I typically try to do things right the first time when modding the car. However, it's also my hobby/toy and am constantly adding or trying new things as I desire. It's not really about the money or being economical, but more about what I want to do and when. I also enjoy doing the majority of the work myself or with my dad on the vehicle. It's my release from being CEO of a company and having a wife and 4 kids. So it's possible I go E-85 down the road, but just really have no desire to do it right now.

Not having to run your tank to near empty anytime you want to switch fuels is the downside of uprev, having the ability to run a mixture of both fuels and a gauge to tell you the content and having the ecu automatically adjust timing according the the E content is worth the extra time and trouble of the install. Putting your hard earn time and money into something done right the first is a must. Plus staying NA and not have a supper aggressive map you could probably get away with it and be fine.

I don't have E85 local to me, but I know roughly where the stations are. It is a little trouble, but I try to plan the gas based on the distance if at all possible. Like for ZDayz next week, I'll be leaving the house with about a 1/4 of tank to get to an E station and fill up there. If it's too far out of the way to hit another 1, I'll just default back to pump 93. Sorta sucks, but I knew going in it would be the exception, not the norm.

production engines only right? I know of more than a few spec race engines that do well into 150hp/l
