If you are looking for a cheaper alternative to a V8 swap in your Miata you may want to consider a Honda J-series V6. Mini Tec sells a JV6 swap kit for $3,500 that will allow you to swap any 1999-2007 Honda J engine to any NA or NB Miata (1990-2005). Although the 3.2 L from a 2003 Acura CL Type-S with a manual transmission is probably the best option since you can use the stock ECU. The beauty of this kit is only needing to replace the engine. Mini Tec supplies you with everything you need in the kit and the transmission, driveshaft, diff, and radiator remains stock.

Hi
Does the mintec sv6 kit work in right hand drive application.
I contacted the company and they stated it will work.
What j series engines can you use with the kit and are any easier than others I was thinking bout the j37??
the easier ones are the earlier ones with cable throttle and manual trans.
Really interest in your Honda J Series to Miata swap kits. Would you mind listing what items are included in the kits. I’ve watched several videos about that have peaked my interest but I’m unable to identify exactly what comes in the kit.
Thanks,
Ken
Hi Ken. Mini Tec lists the parts of their kit in the link below. I also recommend contacting them directly for more details.

If I swapped my na Miata trans (5 speed manual) with a nb ( 6 speed manual) transmission, will the engine swap still work?
Will the 3.5 L J35Y6 V6 engine fit without problem on this kit? Any mods I have to do?
Do you have of these J series swap kits available for NC miatas? like a 2006?
I recommend contacting Mini Tec directly.
I’d like to ask if I can order the kit with an adapter plate to a different transmission? Preferably a Tremec t5 or t56 or cd009 or something that will hold more power
Hi James. I recommend contacting InlinePro. They offer an adapter plate for the CD009.

Is there a Miata NC kit for the Honda J series engine swap
Hi Reginald. I don’t know of one. You might want to contact MiniTec to see if they are developing one. The only other V6 swap kit for the NC is V8 Roadster’s kit for the GM LFX V6.

What transmission are recommended to replace the 5 speed manual in the NA versions. Those are known to not do well over 250 hp so if I did this swap I would want to update my transmission soon, as well.
Are there any single kits that have all the parts needed for a stock NB LS 2003 Miata? Also, can I swap the Honda J engine without needing to replace the wiring harness?
I have a 1995 miata and im trying to do an engine swap, what would be the best engine to fit in it.
Do you know if the 04-08′ Acura TL j32a3 works with the kit?
Hi Sullivan. MiniTec’s installation manual says the kit uses motors from the 2001-2003 Acura CL Type S or 2002-2004 Honda Odyssey. We recommend contacting them directly to inquire if other engine years will work.
If I j30a swap a Miata can I run the tock ecu?
