Glad it's working out. Biggest problem for me is retraining my muscle memory as to what gear I should be in. The CD009 gear spread really works well in my opinion.

It's pretty much hidden. There have been a few install posts on ClassicZcar including the one I did. I suggest you give this a look.

I manufacture a CD009 conversion bell housing for the L6. I sell them through Godzilla Raceworks. https://www.godzillaraceworks.com/drivetrain/cd00a-swap-bellhousing-kit-for-l-series-engines It uses your existing clutch pressure plate and flywheel which is nice.

I run the Vintage Air Gen 2 Mini. I had all the other stuff already so I didn't need a kit just the evap/heater unit. It fits under the dash really well.

This is it exactly. The more lopey the idle the more I notice it. My aluminum flywheel isn't helping either. A steel one would have a more damping effect. It's subjective and a camera phone is not going to pick up a true recording. The next time I pull the transmission I'm going to put some DEI Floor and Tunnel Shield in. I think that would help a bunch. I hated the noise when I did the install but as AydinZ71 said it's a known thing and after a while it's not a big deal. I love having the 6 speed though so it's a worthwhile conversion to me. Back in the day they called the Muncie M22 "Ro

I’m sure OSHA would have no complaints with anything in this picture:) Now that I have a surfacer I’ve decided to play around with CC’ing chambers after I make my final pass. When I originally modeled the chamber in 3D I left a 1mm straight wall plus machine allowance for the builder. The reason for that was to create a known steady surface area if you wanted to really dial in the chamber volume. A .010” surface cut will remove approximately 1.3 CC’s. The problem is Even though there are seats in the head you can’t put valves in since the guides are not sized and even if you coul

You beat me to it It was a lot better than I was expecting and mostly accurate. I'm glad they kept the HybridZ origins in there and a link to the page also.

Is that built out of GPO3?

Ok well we know it will go to 3.4. Still a lot of questions though. Also the lack of actual pictures of the MRZ 3.4 DOHC makes me wonder. I will say that knowing MRZ's price points even if they offered a head like mine it would be pricey.

Nope. I saw that awhile ago and assumed that they were either developing their own head or had made a deal with OSG to buy complete motors. It also say's Nissan 3400 straight 6. Neither the OSG nor mine is a Nissan product so I'm not sure what is going on. I suppose they could be doing some sort of RB thing. Can you get an RB out to 3.4? I don't think the head will flow enough to feed it though in a NA application.

I am but as soon as I put bungs there I guarantee you someone will want them somewhere else. Also the majority of the builds are running Jenvey stuff and for the most part they come with bungs. And last but not least the casting works for both tilts depending on how I machine it. The bungs would over complicate that.

I think Derek's injectors are at the head I purposely have left that stuff up to others since A: I know very little about making power and B I know even less than that I do know how to make a casting though so that's more important in my mind. I did a search on production vehicles that make over 100 HP per liter NA and it's a pretty impressive list. Rob sent me a link to an article that came out. https://www.thedrive.com/news/41805/nissan-240z-roars-with-honda-style-dohc-head Links to and mentions this build thread which was nice.

Thanks Ben I'm glad some numbers on a 3.2L (3.18) are finally out. 100hp per liter is pretty decent from what I hear. Rob feels like there is still some more to be had via tuning but it's a street car so there is always a balance to strike. I'm just glad that for Zcar Garage it's now an itch they need to scratch.

I own one and the videos even got my blood pumping. That car is really amazing. Hopefully after this round of heads I'll be able to finally finish my 3.1 ish build. I will say that the sound is pretty much the same with mine. It's really great that now there are some real HP numbers on the head. It's an expensive head for sure but getting 350HP at the wheel out of a regular ported head wouldn't be cheap. The best part is that is the SEMA car that HAD the OSG head. Had..... Bwahaha

Looks great. I think you drove mine at Bill's if I remember correctly. That was with Rfactor. It's up in a pallet rack since I seem to have ZERO free time these days. How do you like the VR vs monitor?
