Hey guys i am new to the website so hoping i put this in the right forum, but anyways i was hoping you guys could answer a question for me. I have a 2004 S2000 and recently i blew my motor so i found a JDM F20C motor that i am going to purchase, and this may or may not be a stupid question but was wondering if it would work in my AP2 without any problems or extra parts, because i know when putting an F22 in a AP1 you need an engine harness. Couldnt find any info on the internet about vice versa, so thought id ask you guys. Thanks.

 

Wrong. When you put an F22c in an AP1 you do NOT need an engine harness. 2004-2005 F22c longblocks drop straight into an AP1, with no modifications or extra parts needed. Ask me how I know.

Anyways, I'm not sure of the feasibility of putting an F20c into an AP2. However I do know the 2006s and newer had DBW, which is something that might present a problem. I'd imagine 2004-2005 would be easier... Not sure though.

The bigger question though is, why would you put in an F20c into an AP2? Just to save money?

 

oh okay haha, thanks for the correction

I think in Japan they had the F20C motor till the 2006 came out, so im hoping the F20 should drop right into a 2004, correct me if im wrong again haha and yes mainly to save money.

 

Check to see if japans F20c for 06+ came drive by wire, I'm not sure. The problem I see using a F20c in ap2 is the fuel map, it could be too lean. You my have to use a richer fuel map

 

f20c + ap2 i think is the best combo! only thing i wish on my s2000 had was the better trans (carbon)

 

the JDM F20 motor i am purchasing does have an amuse ecu.. think that makes a difference with the fuel map, not sure tho.

 

is there anything needed to install the f20 into the ap2?? or does it just drop right in

 

F22c running to 9k RPMs with AP1 trans is the best actually.

 

I agree, more power longer gearing

 

How do I get my f22 to rev 9K?
