After a weekend of hard driving my faithful s2000 may have finally blown something in the engine. I've had her for three years, she's a 2004 in a beautiful silverstone grey. I'm trying to decide to rebuild the engine currently in her, swap it out for another one with hopefully 30-60k miles (135k on her now) or swap in an f20. Will the f20 bolt right on to the f22's transmission? If i do need a new engine whats a good website to source one from? I'm not looking for it to be built, i want used 30-60k miles. No more than 80k, I'm brand new to the forums so if there's a thread already for this i'm sorry for the double post! Thank's gents!

Yeah the f20 will bolt right in, but without a ap1 ecu your only going to get 8k rpm out of it rather then 9k. You can swap in ap1 ecu with a little fuss, but regardless the F22 is a better motor all the way around, I wouldn't do the swap.

Engine swaps are fraught with problems and changing to a different type makes it worse. An '04-'05 engine is what you have and what you should fit.

There are two generations of the F22 engine. The '04-'05 and '06-later. The last is DBW with a unique induction and fuel system. You have the earlier version.

I would bet a swap with a used, low-mileage, bone-stock engine will be 100x more reliable than a rebuild.
Because, aren't F-series very difficult to rebuild?
I've seen many professionally rebuilt B-series and H-series back in the day ('90s) last not more than 30k miles (and these are supposedly much easier to rebuild than F series). Rebuilds always spin a bearing or develop rod-knock somewhere down the line, unlike oem stock.

Get the low mileage F22. I went from an F20 to an F22 and I will never go back. I don't miss the misfires and oil burning.

The drop in trq of the F20 will also be noticeable. Remember the 04+ put on about 80lb over the ap1. Swapping a F20 in that chassis is a general downgrade in all aspects.

hahaha is this first hand experience of the "fraught with problems" or of what you've seen on here?

When my F20 took a dump in my ap1 I swapped in an F22 no problem and would never go back to another F20. Its 100% bolt in and go, nothing to swap, nothing to convert. I even run the ap1 original ecu to the car and enjoy having the added over rev with the F22 power plant.

Like all f20's missfires and burns oil ....

A f22 is simply a superior engine over the f20 because it makes more hp and tq. If I had to swap an engine in to any s2000 it would never be an f20. This is coming from me with a 2002 ap1 with a stock block f20 with 130,000 miles making 600whp.
