PnP BP6D head with Tomei Cams and SUB conversion - prepare for sticker shock
 

SOLD SOLD SOLD SOLD


So I'm volleying between a bunch of things in life right now. Between job applications and surprise expenses, particularly my diff blowing, and property taxes this year I'm rethinking the direction I want to take with Smurfette. . I've had a reality check on my expectations and am, once again, on the fence of running this head I had built and stashed away for my last grand BP motor build.

Vlad already tuned this thing to be terrifying in 4th gear on street tires, and the only reason I'd run this head is for glory, but I care a little less and less about this these days. I have body work, a motor rebuild, and now fixing an OSGiken rear diff to worry about. More power is the last thing I need on the list. By relinquishing this head, it would liquefy assets to be used in more meaningful ways and get the car back on the road faster. I'm also trying to save for the KMiata trans kit, and this would be an ultimate chunk of that.

There is a lot invested into this head, so be prepared for sticker shock. It's more than your run of the mill head refresh, but less than a CNC Supermiata superduper head. This isn't for everyone, and the market that will appreciate this is small so please don't waste my time lowballing if you can avoid it. I've already lost money on this listing it.

All work, cleaning, assembly, adjustments have been done by Headgames Motorworks which is relatively popular in the Honda, Supra and Viper communities. They agreed to do this head even though it's not in their normal line of work. Check out their site for tons of pretty pictures: HeadGames Motorworks



Since my valves are in place, I can't take as awesome photos with lights shining through ports, so I did the best I could below:

If you made it this far, and are perhaps interested in saving you some dosh, and more importantly, time from waiting for parts and machine shops.....then let's talk.

For this fresh built / never installed / 0 mile VVT head for your wild motor build with all the components you could probably want to do to a head without going full custom,
I'd love to see $4300 for this thing.

Thanks for looking, and thanks for trying to get my Smurfette on a path to reliability.

Would there be a downside to running the double valve springs N/A?

No. Folks use heavier spring rates to increase their mechanical rev limit. Supermiata estimates that these springs will sustain revs to 8500rpm.

Now I need the miata turbo go fund me for science more than ever. Wish I had the budget for this but the car is on the back burner for a while.

I was hoping to use it as a direct comparison since the rest of my setup hasn't changed. My drivetrain is struggling though. I don't have a cage, and for a street car, I really don't need more power.

Any chance you'd be willing to separate out the head / cams? I have no need for the cams as I have my own set of bigger VVT cams waiting to drop in. Just lazy and waiting to get my headwork done at this point.

If you can set something up with vteckiller, he had expressed interest in the cams. Might be able to just cut a deal and relinquish the SUB conversion and shims with the Tomei if you plan on running stock stuff.

I personally would love to sell this ready to go. Things can be split after the fact if there's a second buyer in line.

would you sell the coolant reroute?

I'd leave it to whomever wants to buy the head and split the parts to decide. I'd like to sell this whole. If you're interested in the reroute, if vteckiller still has interest in cams, and albumleaf just wants the valvetrain/head...you all might be able to come to an arrangement. I'm not trying to be a jerk, but there's a lot more going with my car on that has monpolized my immediate attention. I beg your understanding as a fellow buyer, seller and enthusiast.

trade your a turbo manifold for it.

Let's talk ;)

I'm a giant ashole...

100% correct. so keep your crap inside and stay shut or I'll do you a favor

Ban me if this is the way the moderators run things

Happy to help out. Who else wants to test me?

Again, this is only going to be interesting to a small niche. This is probably for those who want an easy button to save time and a bit of cash, or literally have done everything else under the sun on a BP and can't go much further without headwork. Everyone is free to value their time and investment diffrently, what is right for you, may not be right for another. I appreciate any constructive comments, but I thought I was pretty transparent one takes the time to actually read the listing.

If folks want individual components bad enough, then it'd be pretty easy to step up to the plate and work out details amongst other interested parties.

You don't need to be modest. This is an awesome setup and anyone with an IQ higher than 2 will know it's value. Poverty ridden dumb n00bs who "built their car for under 1k total" need not apply.

Bump for seriously awesome part and a good/honest seller :)

ditto this

easy button on the head, which has few easy buttons. If I knew then what I know now, and this popped up, I would be sending an offer.

But hey when you want to turbo your car for under 1k you have to cut corners and just maybe have you downpipe explode:rofl:


Really though this head is awesome
