well i put an F20B in my eg this past summer along with the hytec rep. header and aem intake... and made 178whp, 135tq on a chipped p28 w. neptune...

looking for some insight on what would help me get to 200 NA before nitrous...

on a side note man am i glad that my computer has decided to let me back on H-T ive had to search here through proxy's and it ****ing sucked lol

here is a pic of the setup


looking for the perfect h22 cam that is streetable

 

pro1 or pro2 cams

 

I made 200whp/156wtq using Pro2 cams and Pro Series valvetrain with my H22 stock block after the Hytech Rep header. Your torque is a little but of course we all know that the F20B lack a bit of torque.

You mentioned you have a Hytech Rep header but your picture is showing that you have a RMF Long Tube header??

 

Where can 1 find the Hytech rep header I'm G2b

 

i made 185hp and 135 tourqe with my stock f20b with the same rmf header. Did your motor come out of a five speed ? what trany are you running ? balance shaft removal kit would get you 8hp. Your motor has type s cams if it is a five speed motor . The up side to that is it comes with type s springs and retainers there realy good . Ive been running my springs and retainers out of my f20b on skunk2 stage2 cams for years. I have pro2 cams on them now no problems at all . It comes with 11.1 compression and if its a five speed motor you dont need to upgrade springs id threw in a set of pro2s and call it a day. What exaust you running?

 

wouldnt that header hurt your power some on a stock motor???

 

Just do the essentials: CAI, Intake Manifold and TB, cam gears, header (I have the RMF Drag Header), catback and chip. You have the same RMF 4-1 Drag Header like mine. That header is suppose be worth 10 to 15 horses (See Included Dyno) by just installing it with no additional tuning. I will be installing mine in March. My completely stock F20B put out 185 and 145. With a CAI and catback it now puts out 192 and 153 (See Included Dyno) on the same dyno. I live in Tokyo and the dyno is a Super Autobaccs dyno that is very well maintained and constantly calibrated. With Skunk2 Stage II Tuner cams (very streetable) and all the other bolt ons you should be able to hit 200.

Really didnt know Type S springs could handle Tuner Stage 2 cams.... I always believed they could. Thanx for the confirmation. Now that I know, I will purchase titanium retainers and cams only.

Did you get dyno confirmation of the 8 horse increase on the balance shaft removal?




Private Label MFG. RMF 4-1 Drag Header--Untuned

 

BTW.... What RPM where you/are shifting at with the Type S springs? I plan on shifting around 8500-9000 RPM.

 

remove the balance shafts and get the euro R intake manifold and pro1 cams and u'll be around 210 whp easily.
mine made 203whp with a cheap e-bay header.

 

lol rmf, hytec, kidd racing, **** there are so many i dont even know what it is anymore lol

thanks for all the comments guys, i see the dyno graph says its on a dynojet, which reads a little higher... mine was done on a dynapack, which was calibrated a day before my tuning so my numbers are exact, there was another F20B with less mods that made 190 on the same dynapack but was way out, lol it said a d-series was making 300hp on an ebay 57trim and 10psi, which we all know would not happen!

yeah my tuner recommended the pro1's i thought about a skunk2 mani and just bending the firewall back a little and moving the brake lines down a little bit.

the car is also running the LSDmotorsport 6 puck clutch and pressure plate. rated at 380ft.lb. so i think i am good for a while there.

yeah wishing i would have the same tq. as an h22 lol looking to pick up a wet nitrous kit here before march and hit the dyno again and then get some track times. im currently running the h22si tranny

 

If your looking for a set of budget cams you could try the blox B's. I tuned a stock bottom end h22a with them with stock port head, SSR header, and euro r manifold.
Made 236hp 165 ish TQ. It was H2B though but still even through an H trans should have been around the 215 HP mark.
Ran 11.80's @115 in a 2150 LB EF hatch.
Good Luck

 

thats really good, i dont set my goals very high but i was hoping for like 110mph traps with cams and nitrous... my best trap last year on the h22 trans was 95mph

 

i just got off the phone with summit racing and ordering my nitrous express wet kit. probably going to order wheels and cams here before the end of the month.

 

anyone else have any F20B dynos to post up?

i believe this motor has a lot of potential with a 75 shot, providing the tuning... my goal by the end of this upcoming drag season is to hit a 12.9 at least on nitrous.

 

I will be dynoing my F20B again in March. Sittting at 192 and 153 presently. With the addition of a Private Label 4-1 Drag Header, intake manifold and TB, custom ECU, cam gears, Blox B cams, plugs, wires and a voltage/grounding system I hope to reach 225 and 165.

 

great ideas from everyone.... im supposed to be getting my delta regrinds back here shortly i got a 272 regrind. so since i already have the dual valve springs i will just get some titanium retainers, and take it to 8500-9

i also picked up an rbc manifold to do the qsd adapter plate setup..

how hard is it to do the kaizen speed BS eliminator kit? i guess im asking how hard is it to pull the balance shafts out? and is it worth it in a daily driven car?

 

i reveed my f20b to 9,000 but ive never reveed my h22 past 8500 as it doesnt make power past that . Yes if you look ther are tones of dyno charts of atleast 8hp from just the balance shafts plus it increases oil pressure. I have heard up to 15hp but i would bet closer to 8 wheel hp.

Ive checked spring pressur and the exhaust side of the f20b are the stock intake side so only the intake side of the type s valve train is upograded . however i have been running the same stock f20b springs and retainers on my stage 2cams and pro 2 cams for years no problems . Make sure you check all your clerances like you should do in any cam installation.

 

Im also making 252hp on the rmf dragg header so i wouldnt change it its fine .

 

what is your list of mods... i would kill for that kind of daily driven all motor power in my hatch

 

replace stock f20b head with a stock 98+ h22a head you will pick up power due to the bigger valves in the h22a head also some pro 1 cams. you should easily make well over 200whp.

 

I would be willing to bet that the 1mm bigger intake valve wouldnt make 2hp diffeence on this size engine if any at all so dont waste your money right now . If you want to pick up a h22 head and have it ported and polished so you could sapp them out later that wouldnt hurt. As he stated the f20b does have a 1mm smaller intake valve so if your going to put money in having one ported buy a h22 head . The 1mm smaller intake valve on the f20b wasnt because the 2.0 litre needed less air .The f20b actually makes peak hp higher there for is probably real close to the h22 in the volume of air it needs . They actually did it to help it revee higher . I am not sure how that works but i did alot of research on this motor tears ago and that was what was stated by honda.

 

Some good info here, any advice on putting a F20b manual head onto a H22a4 bottem end? Reason i ask is this is pretty much all that is available in my country, i dont have access to H23 or Type S h22 motors and headwork is very expensive, thank you.

 

I'm willing to bet your wrong about a 16mm difference not making any more power all through the power band. Your also incorrect about the engine reving higher due to smaller valves. The engine revs higher and easier due to less mass on the rotating assembly thus being a shorter stroke motor which lands it in between a b18b and b18c crank which have 87.2mm and 89mm strokes. you can make any engine rev higher and faster by reducing the mass of the rotating assembly, knife edging the crank lighter pistons, rods, valves. a short stroke motor will make more power than a long stroke motor cause you have more dwell time up at TDC.

 

take the cams out of the f20b head and use them in the h22a4 head. the f20b has smaller valves and is very similar to the h22a4 head.
