Though another thought came into my mind, if you are to swap anyways, why not start off with a lighter chassis. The Kswap has been done to NA/NB chassis for a few years already and they weight in @ about 2300lbs! Those are also awesome chassis from a driving perspective.

How much does an old 240Z chassis, with drivetrain, weight?

Stock weight for 1970-1972 ~2300 lb. I didn't do any real light-weighting to my '71, with bored/stroked L28 swap, 5-speed, R200 diff, roll bar mine weighed ~2300-2350 lb. with ~1/2-tank of fuel IIRC. With a full tank and me in the car weight distribution was slightly rearward of 50/50, ~49.8/50.2 again IIRC. With big cast-iron I-6...

My complaint about the FA is in regards to track use. I wish it was more reliable or could build more power NA. I would be happy with just the reliable part. I don't like wondering if this is going to be the day this motor kicks out it's rocker arms or is going to spin a rod bearing because it's oiling system can't even handle the lateral G's street tires can generate in certain situations. It doesn't help that it is a nightmare to work on.

I would consider the swap if my motor went, and if I had an itch for something different. Maybe someday.

Sell '13, buy lightly-used '15+ (or '17+), track away and don't worry. As much...

Crash safety regulations? Have you seen the 370Z engine bay? The hood just barely clears the engine. You don't need 2-3" in between the two for pedestrian safety. You only need .8" as a minimum per regs from 2012 at least. There maybe new minimum bumper and leading edge of the hood regs that a S2000 wouldn't pass but the engine height to hood wouldn't be the issue. Its mounted lower than a current MX5.. |

Here is a good thread talking about dyno numbers from mostly bolt-ons like a CAI, header, aftermarket intake manifold, pump/E85, etc with a stock TSX K24 aka K24A2. Like I said, the FA24 will probably be pretty close with the same modifications. I couldn't tell you which motor will be more reliable on the track. @CSG Mike would have a better idea. https://www.k20a.org/threads/stock-k...27-188.109698/

Im a rsx type s owner. The k20 (type s) head flows better than k24. Most k20 and k24 owners do a hybrid build. A k20 head with the k24 block for bigger displacement and torque with a 8k-9k rpm rev limit. Most k20/24 builds can push 350hp all motor reliably. Sent from my iPhone using Tapatalk |

The K24 has a 87x99 bore and stroke, so relatively speaking, that is a long stroke. The 2AZ, aka the Scion TC's 2.4L, has a 86x96 bore and stroke, so slightly shorter by 3mm. The 2AZ motor might be higher and be less compact than the K24 or not; I don't know. Regardless, here is a 2AZ installed in a FRS against the stock transmission:
