Single Cam F-Series Weight?


Recommended Posts

Posted

Honda make two different F-series engines:

• the single cam, sister engine to the H-series which came in base model Accords & Preludes

• and the twin cam F-series (which shares parts with the K-series) that came in the S2000s

 

According to the H1 weights below, there is no distinction between the two and only the S2000 engine is classed:

 

All Honda/Acura All D-series Single Cam 1950

All Honda/Acura All B16-series Must use B16 Crank 2100 All Honda/Acura All B18, B20, others not listed 2250

All Honda/Acura All K20 & H series See sec. 9.3.1(h) 2400

All Honda/Acura All K24 See sec. 9.3.1(h) 2450 All Honda/Acura

All F/C- series 2.0 Liter 2700

All Honda/Acura All F/C- series 2.2 Liter 2800

 

Can I please have an official ruling that the single-cam F-motor falls under the "others not listed" which run at a weight of 2250...

 

Thanks in advance.

EDIT: Turns out there's also a twin cam F20B Accord engine. I guess I'd also wonder if that falls under the "others not listed" clause...

while that would be nice, I can easily make a h22 crank, rod, piston, and head fit my f22a1 block. I think that means it needs the same weight as the H22 at 2400.

 

We just need to designate the s2000 motor at the higher weight.

IIRC, it was our intention that those engines would fall under 'others not listed'.

That's all I needed to hear. Thanks Mike.

I believe we thought that the F/C designation would be 'known' as the S2K motors. While anything is possible, it would be very, very hard to drop S2K motor in another Honda/Acura.

Um, yeah. Hard to imagine there being much advantage to building a RWD, 2700lb. S2000 powered CRX...

Hey, quit jackin' my thread with rear-drive CRX crap.

 

I just wanted the officials to confirm the F-22 and F-23 get to run at 2250...
