So a decision has been made and the process has started. My choice was between the Honda K series 4 cylinder engine and the Honda J series 6 cylinder. I finally picked the K series because I think it fits the car better and is actually lighter than the Miata engine it replaces. The fact that the guys making the K series Miata swap kit are about 15 miles from my house was a big factor in my decision.
http://www.kmiata.com/home.htmlI don't need most of there parts, just the manifold adapter, engine adapter plate and flywheel. I don't need there sump/oil pump setup as I don't have issues with steering rack clearance.
My plan it to get the engineering done first, so installing the engine, getting the exhaust built, check for hood clearance. Once I have the basic engineering done I will order the flywheel. So I have ordered the S2000 manifold adapter and the engine adapter. I already have the manifold adapter and the engine adapter plate should be here by Xmas.
I spotted the engine for sale locally on Ebay for $1600. A 2007 2.4 Acura TSX engine K24A2 with 70k mikes. It's probably the most desirable of the US supplied engines. 205bhp @ 7k stock. I made an offer and ending up talking to the owner about removing some parts I did not need to reduce the price. We came up with $1350 is he removed the intake system including throttle body, exhaust header, PS pump and AC. I just wanted the alternator, starter and the engine harness and the power harness. When I went to pick the engine up I was surprised to see all the parts still attached. He said he had not had time to remove them and he had a dinner date with his wife he was not going to be late for, so I could have the complete motor for the agreed price of $1350. So I hope be selling of the parts I don't use I can get a couple of hundred dollars back.
