Iv searched around and I really haven't been able to find much if any real collection of F series ALL MOTOR builds. Iv seen some impressive turbo setups but im after the NA's.

I love the idea of a built F, not a hater of the B's or the H's i just like the idea of goin a different route and would love to see some F series torque monsters! ... Anyone?
Im curious how well these engines could perform with a high compression etc setup, I know of Bisimoto but I'd like to see what the average person can do ha.

 

Have you checked the forums on Bisi's website? If not, you might want to check there for some builds. I'm sorry if I couldn't give you any more info.

 

nobody has really done anything exceptional with an F and shared the results online. I've seen approximately 170whp on F22 and F23 but nothing more. Of course, neither of those were really "built" just modded. Still, the lack of overall support makes it pretty frustrating to do. Bisi does make everything you'd need for an F22A, and has tons of followers, yet nobody has posted a great dyno sheet as of yet.

 

How about a 300hp NA Fwd F20c ? lol

 

Oh i know about Bisi, but i wanted to hear from some people from this site. I have seen Pirates G23 build (epic epic build from start to finish) and AFA's but i just done see alot of people posting up graphs, or maybe the crappy search is working against my search for them.

Either way i find it hard to beleive that theres is such a small handful of people who have taken to the F. I wouldn't even mind seeing some results of bolt ons, I just feel its always been an underappreciated foundation for a solid engine build. But thats just me, i myself have not really done anything to an F series but i still feel theres a lot of room for improvement with good potential.

 

bisi made alot of support for the f series. he currently holds the record for the fastest/highest hp n/a f series. pushing over 400hp!

F series are just not popular, but they have more potential then H series

 

more potential then the "H"???
really?

 

Ha i figured it would go like this, i wouldn't say MORE potential than an H but I think its just underestimated. Anyone have any builds or graphs they feel like sharing?

 

I decided from the start that I would stick with my single stick non VTEC F22B2. No graphs for mine yet. Here is the build list, all parts are on site. Saving up $$$$ for machine shop.

96' F22B2 block
Darton M.I.D sleeves
Wiseco slipper skirt pistons (89mm bore, 29mm compression height, .6cc dome)
Carrillo Pro A beam 143mm (H22) connecting rods
Stock 95mm Crankshaft
Kazenspeed balance shaft eliminator
Modified OEM oil pump
Remote oil filter & oil cooler

96' F22B2 Head
DIY port and polish
Regrind Camshaft
34mm Stainless Steel intake valves
30mm Ferrea supper Alloy exhaust valves
Bronzed valve guides
Ti retainers & seats
Upgraded valve springs (signals)
New rocker assembly (balanced)

96' F22B1 Intake manifold (slightly modified)
Set of Keihin 4 x 46mm throttle bodies
2 stage fuel injection
Primary fuel injectors - 450cc Peak & Hold
Secondary fuel injectors 240cc Saturated

Transmission
Currently 96' F22 5spd (Looking for an H23 5spd)
Fidanza light weight flywheel
Fidanza 3.2 4 puck Kevlar clutch kit

In the end this will be an 89mm x 95mm, 12:1 CR, 1.56 R/S F22B2 stamped block

I guess it's not really an F22B2 other than the stamp on the block & head. It's not like I spent $1300 for the block though. I should of went with an F23 block for what it's worth.

 

i have this build on my favorites (the ITB page you made) and love everybit of it. Im VERY curious to see what this could put down.

few questions though
What kind of cam regrind did you get?
Also any kind of flow charts on head? Just curious how well a DIY job could do, not doubting your work, just curious how well you did (thumbup)
And why f23? I was under the impression they are the same block but with a larger bore (which youve aquired) and a longer stroke (2mm) with 55 mains. You wanted more stroke eh?

 

I haven't had the head flow tested yet. It's in the redesign stage. The images I have up on my build page are of my ports being pretty much completely hogged out at the port entrance. I didn't do much more than clean up the castings of the bowl and throat. I am going to be taking my head and ITB manifold to a local shop to do some testing with different port designs. With both the head and throttles I can get 100% of how everything is going to flow. Also @ $50 for a junkyard F22B2 head. I'm not too concerned at having to use 1 or 2 for R&D...lol

Cam
Dur; Int-260 Ex-238
Lift; Int-0.39 Ex-0.32

The F23's 97mm stroke and the possibility of an 87-88mm bore on stock sleeves would be a nice budget build.

 

Very cool, I'm interested in those head results. but mostly the ITB's... :D

I agree with you about the 2.3 budget opportunity, but as for as stroke, do you plan on different rods or crank? (not really sure if they even make aftermarket stroker cranks for F ) they already have a longer stroke then bore, but just curious if there was a way as to up the Bore as you did, and have some more stroke to go along with it. Might kill the redline, but i think it would prove fun on the street. An F series oozing with low to midrange torque seems more fun to me

 

I'm keeping the 95mm crank paired with the H22 rods.

Yes there are 100mm cranks available for the F22. I looked into one a while back.

 

Oh and don't forget. My R/S with a 95mm crank and 143mm rods is 1.52:1. If I were to go with a 100mm stroke & 139.5mm rods it would be 1.39:1 I was always told the higher the ratio the better for piston reliability.

I'm getting the 139.5mm rods in keeping with using my 29mm compression height pistons. You would usually be using 138mm rods with OEM compression height pistons. That would be an even lower R/S.
