anyone ever hear of a b18 transplant in an accord? i know that it's a reduction in displacement but has it been done? does another cam really make that much of a difference?

 

Yes it will be sick to have more hp and less torque than the stock motor
















....

 

I've been working on compiling the wheel hp/torq dyno graphs of several engine types. One such graph includes the stock Accord F23 Vs. a B-series. The problem with a B-series in an Accord especially a 5th gen or newer. Is its weight. the F-series actually makes way more hp and torque before 6-grand then any B-series. The B-s work in Tegs and Civics b/c they are way light cars in comparison. Better to build an F or swap for an H in an Accord then to ever comtemplate B-series. However, a fully built and turboed B may have promise in an Accord if top end was your goal. A swap I have yet to see which would be killer around town is an F-series into a Civic or Teg. The F-Series and H-series are nearly identical in Hp and Torq until 5000rpm. Swaping an F into a Civic hatch should easily whip up on a B16 and maybe a stock B18C even, it would be a way cheap torq machine. Some European market Accord have 1.8l F-series non-Vtec engines. However, these engines run much higher compression ratios due to better gas then our typical non-vtec F series. In addtion, these engines still have longer strokes then B's which equals better torq.:thumbup:

 

yep I think an F22b1 into a civic would be pretty sweet, only problem is you still have to pay use special mounts like you would for a h22.

I think those Euro-accords are actually smaller than USDM ones so they do have less weight.

I agree about the power F v. H series. There isn't a big difference till VTEC.

 

I was really very surprise once I graphed the results to see the F and H so nearly identical before the preludes vtec kick. The Accord and Lude don't even share the same bore or stroke. A fully built Accord F-series that could handle say a 7-7500 redline on high compression would really be an Awesome torque monster as Hondas go and would likely perform better around town then a stock H-series.

Yes the Civ/Teg crowd would need the special mounts but Vtec F's are so cheap they may even be able to get one for free so I still think it would be an Economical swap over a non-Vtec D or B series for power to start with.

 

i believe this has been done to a hatch and is worth it if you have an Fmotor lying around....don't go put and buy one just for the swap...

 

I think we need some picks of this motor in a hatch!!!

another interesting trend I have noticed is that D-series mock B-series before Vtec just like H/F series model before Vtec switch.

Ok so what? Well D's modified with High comp-ratios and full port work can out perform on the dyno stock B's by a far margine.

Taking this into concideration is it wrong to theorize a fully built High compression (10.5-11:1)SOHC VTEC F22/23 could out perform a stock H22 the way a D16 SOHC VTEC outperforms a stock B16 Vtec? In teresting to note b/c of the D-series longer stroke low end torq is better then that by a small margin of the B16.

These graphs can be constructed from actual wheel dyno graphs from Import Tuner and JG Engine Dynamics web sides if anyone cares.

 

with h22's and f22's sharing the same literage, what's to prevent someone from picking up type s pistons and rods? or even just pistons?

a part's list of swappable internals might be in order... cause i have 2 spare f23's laying in my garage, both with pistons so if i can make some power on my f22 by swapping those out then **** lets get to it...

 

yeah boy!

sorry... got lost and had to get in on it...

 

i dunno if anyones mentioned this, but if you own a 3rd gen accord then the common swap to do is a b16 or b18. However yeah, 4th gen and up, I'd say h22 is more practical.
