I wonder if they can get an AJ30 to put out 300hp.

I was watching his videos a while back, tracking his progress. He had a few setbacks as he didn't upgrade the clutch and LSD from the outset. Predictable, but at least it was sorted in the end. Looks like fun now with circa 320bhp

that thing Canoeing goes. what a decent v6. unlike the usual low power stuff people use here, KL etc. The AJ jag engines do better but still only c. 250bhp from memory without major work.

Hmm, interesting. Sounds like it needs a lighter flywheel & a stronger clutch though.

To be fair the LFX is a fair bit larger than the 3.0 Jag unit at 3.6 litres. Dropping in different pistons can give you more cc in a J series, so another option. Although going for a UK engine and swap kit would certainly save you time, money and hassle! If you are going to go forced induction I guess a smaller engine isn't a big deal anyway.
Loads of cool options whatever. I'd like to see a K24 with a mental NA build over here. The power figures can be really quite shocking. If you can handle wearing ear plugs everywhere |

yeah keeping an eye out for blackcat's K-series conversions. Have a mk2.5 RS that could make a nice host for one...

Back when I was looking and researching all the cool options were import only. So whatever I went for was going to cost. At that point it was down to things like sound, for me. As much as I considered a K engine for a while (low weight, great tuning potential) I decided... Do I really want to spend thousands of pounds to end up with another four pot? Sounds a bit harsh when you say that, but it is a consideration.
The right V6 can be a sweet spot. Better sounds than a four pot. Much smoother. Very similar weight on some due to alloy block v cast iron Mazda. Less to go wrong as you have no forced induction plumbing, heat, belts or torque spike going through the transmission. But way less weight than any V8 conversion out there.
However... If there was a UK option for a Honda K series swap that would be an excellent choice. No international postage or import tax for a start. There are loads of 2.0 Type R engines about. If you could do this more economically it would be a great option.

I've seen figures of about 4000gbp thrown about as a ballpark cost for the Blackcat K20 swap (if it ever hits the market). Once you add an engine that is about 60-70hp down on an ajV6, but about a 1000quid more expensive for a decent one and it just wouldn't make sense. The kits would have to cost less than half that to compete (unless you already have a shed filled with Honda parts). The 949 racing K20 miata was sobering in that respect. 20000$ invested for 213whp that any TD04 swap costing peanuts will produce..thats a lot of money for imho not enough of an improvement. Also have a read of this thread: www.trackjunkies.org/topic/4599-shukas-tt3st3-k24-miata-build/Its a very cool build, but after seeing the trouble he's had with the swap kit I'm not convinced that the K20/24 is that much more reliable than a turbo BP for track use. Same goes for the LFX swaps. All of them end up having shifting and clutch issues...not a problem if a new gearbox is cheap and available at your local junkyard, but a non-starter in Europe. Its also not a question of not-upgrading parts as the aftermarket clutches seem even worse. |

It's not cheap to do anything properly. As said somewhere else, a proper turbo build on an MX5 will be £8k. Not for bolt ons. But if you rebuild and forge the mazda engine so it will last. Don't forget a supercharger or turbo on a Honda engine can make a lot more than the mazda too. So if you compare like for like... how about +500bhp with a honda four pot. Thats the potential. Some go over double that in USA.
Swaps are not about competing with bolt on turbos. They offer a completely different solution. If you want to be different, thats a route available. Cars which are a bit different will always sell for more money down the line as well. Look how much Flyin Miata V8 cars command as one example. Sometimes up to ten times a typical MX5, from ads I've seen. When 99.9% have either a bog standard car or a bolt on turbo kit the market is flooded with those sort of cars.
Ages ago I saw an example of an old cortina or something. Back then it would have been about five grand as it was clean. But a dealer sold it for about 18k as it had an S2000 engine swap. There will always be buyers for something a bit different.
Not that we do this for money or getting it back!! Just saying... I don't think these kits need to "compete" with bolt ons.

Massive turbo boost v no boost... Great lap. Respect to both drivers. Great stuff 😎
