hello from greece

i have a euro ee9_b16a1
i had a built gsr about 190whp about 13.522-167km/h@1/4mile - street tires-full int

i moved on the b20 world... (i hope i didnt do a mistake)
its a stock sleeve block which i (YES I AM STUPID) bored to 84.5mm, i didnt know much about those sleeves ... when i did that
anyway i installed a type-r crank 87.2mm,mainly to reduce the side load-rod angle to those weak sleeves
i have eagle rods , je 10.6 pistons , a milled stock port gsr head so my c/r is about 11.1-11.2
i choosed that, just to give those sleeves a chance... even if i have to use milder cams n stuff.

toda b cams
block guard
skunk 2 pro ima
crower cam gears
ferrea springs-retainers
dc header for b18c
2.5inch custom ss exaust
decat
stock pwo obd0/ bre tuned (properly.. mucho exprerience)
type-r intake valves
acl bearings -loose clearances
b18c oil pump
b20 water pump
hks spf with custom intake insulated pipe
70mm bbk t/b

i havent been on the dyno yet
the car is street tuned at 12.9 afr wot / max 27deg map ign adv
i always use 100ron gas
cams at 0,0 i ll play on the dyno

now to the questions..

what should i expect with this setup..
i mean , WHAT is holding me back? to reach above 210whp(i dont think i ll go over 200whp )
the shitty for this setup dc header?
the stock maxed 230cfm gsr head? (i suppose)
the toda cams specs??
the low c/r?

maybe major factors are the p72 head, and the dc?
am i right? should i invest on those, what would u do?

the car feels much faster than the b18 , especially in the midrange, but i have the feeling the top end is about the same..
i hope thats the cams just been untuned..

i appreciate any recomendations

sleeves are goin to go

i ve already ordered a sleeved block, so i dont care too much..
i just experimented to see if less sideload, and lower cyl pressures , will help the b20 be reliable..

B20,s are fine as long as you do not overheat, or detonate them, just like other Honda,s. CI sleeves will take more abuse. Just do not abuse them.

You should look into some rc injectors...maybe 310's or bigger.

thanx..
forgot to add..
i only trust honda - keihin
so i got obd2 prelude h22 injectors, bypassed resistor box, and got a walbro 190 lph pump
with the stock 240 inj and the walbro, after 7800 the afr was going abole 13.7 , no matter how much fuel i was adding..
inj above 110%
