Always cryptic with your words sir. They mentioned in the blog there would be a stock ECU option, and Solidsnake11 was running it with ECUTEK. I already have ECUTEK, so should I hang onto that and my stock ECU, or should I get the Haltech? They said to save the stock throttle body from the FA20, but I have pretty much recycled or tossed all the other sensors/parts, so if this is an option then hopefully I didn’t toss other things that are needed.

They also mentioned there would be a base tune on the Haltech to get someone down the road to a dyno tuner.

It isn't cheap, but it isn't all bad. For just doing a straight swap, apples to apples, someone would need a K24A2 engine and their kit and misc parts. A used FA20 engine goes from $2500 minimum, but averages around $3500-4500 from what I have seen on eBay and places. If someone sold their stock engine then they could have some cash to get the swap kit. Even if the rest cost $5k, they have an extra 400cc motor with the potential to add boost to 450whp, which is 100hp more than the stock FA20, and if the engine explodes then a new K24 engine is $750 and not another $4000. Moreover, the platform is much easier to build for NA or boosted power. Piston and rods and basic builds can net 700+whp. Headwork is far easier and probably cheaper on the K24, so apples to apples comparisons, there is something to gain, but it will take money beyond the swap to reap most of the benefits. If all someone did was add the RSX oil pump, installed the VTC gear and headers and E85 then they would be into some decent NA horsepower and have a more reliable engine to take to the track, IMO. This is almost like adding a CARB kit FI boost levels to the FA20, but with 150lbs less weight. Here they show similar mods as I just mentioned hitting around 250whp.

It's never cryptic. It's just enough info for those who care to research on their own, or dig deeper on their own accord.

A guy had a K swap, running on a FA20 ECU, dual injected, boosted, with full VTEC control. Brilliant work.

Oh I recall, and it has been mentioned here. "Imagine if it had been standardized..." dot dot dots made me think you were referring to something in the works, as it 'there is more to come', but I see you were just saying, 'what if?'.

KPower has mentioned a stock ECU option, but I don't know if their solution is the stock K24 ECU without CANBUS, or if it is the FA20 ECU with a K24 piggyback ECU setup, or if it is something similar to what Solidsnake11 did--an adaptation of the FA20 ECU with ECUTEK. I don't think it will be the latter, but anything is possible.

Is it better to go with a K24z7 or the K24a2?

From what I read you can't use a K20 head on the K24Z7. So it ultimately depends on your build goal. I'd also imagine the Z7 is going to be more expensive.

Recommended options from Kpower are the K24A2 or K24Z3.

The K24A2 is what KPower is using for this kit from what I have been told, but they may support the K24Z7 in the future like they do for the Miata. The engine mounts are different, so that would be a critical consideration.

I think the K24A2 will ultimately be better for NA power. The A2 has individual exhaust ports instead of a headifold, and it has VTEC on the exhaust and intake side. It is about half as much money too, as the K24Z7, but more expensive than the K24Z3 ($750 vs $1500+/$350).

The K24Z7 has 11:1 compression vs 10.5:1, and it has stronger rods, from what I have read. It comes with the 50 degree cam, so that doesn't need changing. The exhaust is probably cheaper, easier, lighter and better for packaging, whether we are talking about a NA or turbo setup, but the K24A should still out flow the K24Z because of the exhaust runners and VTEC.

The K24Z would be a good, basic turbo motor. The K24A or K24/K20A Frankenstein would be a better NA motor.

Thanks for that info. Turbo is definitely the route I want to take. I guess wait it out a bit more. O really like the K24Z7. Lowering the comp is no biggie either.

What do you like about it?

I know all about the advantage of the Ks. I have owned a FA5 (along with a long list of Hondas) so i am well versed of their potential. I love high revving Honda engines. But if all you are doing is a swap in stock K20 or K24, i am not sure if it make sense as it's quite expensive to get minimal gains. But once you start modding the K, the power and reliability gain are tremendous. I guess it depends on how far you are willing to take your build.

It's a dream of mine to K swap my 86. I do love the chassis but I will wait for the verdict of Gen 2 before making any final decisions. Have to crunch some serious numbers first and figure out insurance options. Not sure how well they will take to a Honda engine swap, if they will even insure the car afterwards.

I got some more clarifying information.

The initial release will be with the Haltech only, and KPower said they are a Haltech dealer, so they will sell the Haltech with or without the swap package and vice versa, but that their Haltech unit will ship pre-configured for their harness, so don't go buying a Haltech unit beforehand, but if you have one already or can get one cheap, that will work, but it won't be as simple.

They also said the OEM ECU option is not replicating what Solidsnake11 did, using the stock FA20 ECU. They would be using a Hondadata Kpro along with a CANBUS emulator. They have used ECUs there with Kpro installed, so it isn't necessary to source a stock ECU when buying an engine. I asked if the emulator would allow for all features like ABS, TRAC, ESC, and they said that is the goal. I don't know how much cheaper this option may be, but because it requires a used ECU, Kpro and an emulator, it may not be much different than the Haltech, and I'm assuming the Haltech will be superior.

I also asked about something I recalled from an earlier conversation, which is that they are using the front timing chain tensioner cover for an oil return, which makes it far easier than having to tap the pan. While this isn't on their site yet, they will eventually carry it they said:

www.2nrs.com/products/vented-tensioner-cover

Here is a picture of the stock tensioner location and the product. Seems like a no brainer, so I picked it up.

The OEM ecu/translator option will be needed for anyone that needs to pass emissions tests that scan for OBD readiness, standalones don't support that. If you don't need that, the haltech will definitely be the better option.
