We are making an entirely new 8 qt pan in aluminum. To get the 4:1 collector right, it needed to stay on the right side. We also wanted to up the oil sump capacity. So the crossover needed to be moved back. The notched PPF will be reinforced. Hope it all works.

Cool. Obviously you're someone who has no issue with doing some fairly involved fab work, and I like the route you're going. It's one we considered, but ultimately didn't want to make the install outside of the scope of most guys. Can't wait to see the final car.

Shielding or moving the brake and fuel line? I've seen a v8 swap that routed the fuel line near the exhaust. Someone helping on the swap forced a redo on that front because that just doesn't seem like a good idea.

Car is a long way from done. That is one of the many custom things needed to be done.

Does the k20 fit on your NA without chopping up the hood?
I found a k20 locally with now im worried about oiling issues...
Its sump pump vs custom hood

K20 fits under the hood i do believe. K24 requires some valve cover work.

I wonder if anyone has done a stock/stock redline k20a2 swap and ran it on the track without having oil problems

Honestly where are these oil problems coming from, I would say that Kmiata has done a pretty good job of proving out their oil system.

For refference I'm running a mildly ported type s pump with a KJBuilt Spring, I get 30-40 psi hot at idle and 80psi on the throttle.

As far as hood clearance, I just started working on mine.

K24 with Kmiata modified valve cover. I have not cut any bracing yet, it will be very very close once I cut.

I think the oil problems come on the track on high reving k20s. How much was the modified valve cover?

links should hopefully work without hijacking the page

looked at Hytech's site just for funzies, it made me rage pretty hard with how terrible it's set up and no prices anywhere. There must be a good reason for it, but I don't like whatever reason it is

8 quarts?

Just out of curiosity, at what point do you say "eff it!" and try a remote dry-sump?

We sorta did. It has an external vacuum pump. Stock oil pump assembly is gone. The prime concern is with the pickup tube of the K series. That tube is at the core of the K series oiling issues. Some of you know basic formulas for determining flow loss through a tube. The K series plot rolls off then has a knee point where it drops to nil. That corresponds to a specific RPM with the stock gears, slightly higher with a blueprinted/ported pump. John knows the American specialist that designed the oil pump gears for Honda on the K20. The F20C pick up tubs is less than half the length so it doesn't have the issue the K series does. The kit lengthens the K series tube significantly. At lower revs, this can be made to work. At high revs, it will not. This part is not conjecture but something Hytech as a bunch of data on.

So we no have no pick up tube per se. Two separate dry sump style pick ups in a single main sump. That sump is located where the exhaust pass through was.

In the end, it's the time consuming expensive way to address high rpm K series oiling issues in a Miata. The standard kit would be far less attractive to folks if it had been designed like ours. But then most folks will put a K24 in and keep revs under whatever Kmiata tells you.

Vaccuum pump mount grafted onto K mount. ATI damper will have a mandrel coming off the nose for a gilmer belt driving the vacuum pump, I think.

Not to sound like a broken record, but I want to be sure our customers (present and future) know that we've successfully tested our oil pump setup with an unported Type S pump to 8200 rpm for 2.5 years with zero issues, on a stock block K24A2.

I'm certainly not calling John a liar, but there are lots of people in the K series road race community that run big rpm on stock, unported oil pumps for years. There are many drag race guys spinning the stock pump to 10,000+ rpm.

Emilio, you've got a killer setup going here. But I've also received a lot of emails due to this thread and I want to be sure our customers know of the thorough testing we've done with our setup on multiple race tracks.

That being said, I can't wait to see this car done, and I'm bummed I won't be able to see it at Miatas at MRLS!
