Dude. I've said this multiple times. I still make and sell the heads. I have 2 in stock right now. I sold 3 in 2024 and one so far in 2025. I also sold one of my new KN16 4 cylinder heads this year as well.

I agree and I brought that up with him. He had a ton of ITB experience with Megasquirt so I deferred to his expertise. The only complaint I have is when I'm low speed lugging through my neighborhood it really starts lugging. Other than that it runs great as far as I'm concerned. I tend to have my foot in it most of the time though. DOHC and ITBs under load makes for some sweet music

Meh, he's a paid supporter of the site. I figured I'll give him his moneys worth

I have two heads in stock as I type this so the head can actually be purchased. I can't help that you can't afford it. That's a feature not a bug. For the very beginning my goal was to provide the components so that talented engine builders could make the decisions on the types of components they wanted to use. Based on what I've seen and taking the pricing of the relatively simple L6 head as the baseline I highly doubt it. I'm not really sure what I did to put a burr under your saddle but you remind me of the guy that starts a fight in the line to get into the club because he can't afford the cover charge. Just get out of line and go somewhere else.

My tuner has me setup with speed density and a separate idle table. All in all it does fine but the reality is until I build my stroker I have way too much induction for the displacement.

I feel like Megasquirt and ITBs on my car is like a game of whack a mole. Getting it to work under hard pulls isn't an issue but getting it to be tame in normal driving scenarios can be daunting.

I commented on a post about scammer groups and said that if we were still on forums there would be better control of this. Since there are 9 bazillion S30 groups it hardly got seen and the one comment was "forums are too cumbersome" I go there because that's where the customers are but I'll be dammed if I'm going to answer stuff that I know for a fact has been documented in detail on one of the three forums. The answer to every question I see should be "google it"

Man that is so cool. Not as cool as a DOHC though. 😀 I'm for sure going to do this mod at some point especially after seeing how responsive it is. Great job!

On the stock tank? Yes. I haven't started the poly tank install yet. I'm convinced Nissan added the vent on the left side of the tank to deal with the situation. There is no other reason for it to be there. You have to be in just the right climate and usage for it to be a problem. Cool morning fill up, and then parked in the sun all day. There is a real potential to form a vapor bubble there and it expands at a greater rate than liquid. Since I have that plugged the vapors path to release is to force all of the gas that is in the upper section of the tank out if it can. A proper check valve system in the vent line to atmosphere would probably solve it but I'm not crazy about having a pressurized tank. I've just finished testing some polyurethane tubing submerged in gasoline for a few weeks with no sign of degradation. I have a plan to use that as an in-tank vent line. I'll post pictures when I finish it. I also ordered a Tanks Inc. 6" backing ring and I'm going to machine my own custom top plate to provide the inlets and outlets I want.

Not much action here but figured I'd throw it out there. Vintage Tank Solutions vent question For those who are running one of the tanks how did you handle the vent for the fuel neck. Blocking that off means that the tank has to vent through the incoming gas and can be problematic. Just curious what others have done. Thanks, Derek

On the plus side this is the most action this thread has had in ages.

I started typing a number of snarky responses and have settled on Wow what a shitty thing to say.

Congratulations you have finally gotten a "I must have that" out of me. Great job.

Ouch. That means I'm extremely old now I'm wet sanding and buffing my Z and let me tell you I'm feeling all of those 65 years.

I've sold 22 heads.
