VK45 - Long tube headers, JWT S2 Cams, Manifold porting, TB

Finishing up what I hope is a solid NA build. This started off as a GB feeler thread and I finally decided what the **** and pulled the trigger - The custom built 304 SS headers have been the biggest holdup time wise but they are near completion and should be coated early next week. Really looking forward to having my ride back........

Following the build I'll need to re-do my UPREV tune but after it is over I'll be posting GB's for a couple of the parts if anyone is interested. The tech who is making the headers will be making both a version of the long tubes (max power but not cheap) and shorty headers which should come in under 2K and will provide plenty of flow just not as much as the long tubes.

The JWT CAM's may be available for a bulk order. They are actually the VK56 CAM's and there is a slight grind mod that needs to made to the end of each cam before install but its fairly simple for a solid mechanic.

More to follow.

Wow, those pics right there give me wood I'm jealous. I can't wait to see the numbers you make but, almost more importantly, hear how your FX will sound!

Re: VK45 - Long tube headers, JWT S2 Cams, Manifold porting,

Hah! I am really curious about the sound as well, easy enough to guesstimate the power gains but the sound (Db and quality) is an unknown. The 300 cell HFC's are on hand should the Db's get out of control but I want to hear it W/ Long tube headers directly into the Nismo system before we make any changes.

Re: VK45 - Long tube headers, JWT S2 Cams, Manifold porting,

Subscribed to three more weeks in the shop so builder can complete his patterns for additional headers should anyone want them. Man I really wanted this thing back......into the sixth week now and counting. Upside is everything will be done, headers will be in silver chromex not gold now that we have time - additional time will include GT Spec pan install, mid chassis brace, my second GTS lower brace, etc. HFC's will also be in place (not going to take a chance with the sound). I did see the intake manifold and it is amazing, almost looks like chrome.....I had them cut off the engine cover stand offs then reroute all the wiring around it. Curious to see how it comes out.

Told you to be patient

What's another week or so? You'll have PLENTY of time to enjoy it when you get it back. Sounds like a quality job

An over head pic of the bay (tubes and wires are still being routed) with polished manifold, both top and bottom half.
