my b20b dual sidedraft carb dpi nitrous build

i have an 88 accord hatchback dx, u can check it out on 3geez .com, will post some pictures later

here is my build motor goals and partslift first. i havent started building the motor yet, still gathering alot of parts and info. will post pictures soon, just droped camera to get developed. car will prob see some slight street action but not a daily driver, i might take it for a spin every once in a while.

* next to part means i alread have item
? next to item is asking is it a good idea / opinions

alot of the stuff sepecially the suspencion parts i have had new for like 3 years, this project was put on hold 2 years ago just pickiing up again. some of the things i brough back then was when i was in my younger days and dident know any better, but its money spen so i am going to use the stuff.

GOALS
250+ hp range
as much TQ as possiable
12 sec q/m range
8500 rpm redline (i want to be able to rev, we will see how high i can go)
i will mostly be running 93 octane gas, but can get my hands on 110 ($6 a gallon!)

HEAD
as of right now, i have a stock b20b i belive it says p75 head. i might splurge and buy the p8r head
heavy port and polish, with custom portmatched intake for sidedraft carbs
gsr valves & valve guides (if p8r head)
not decided on cams yet
retainers and springs
custom intake manifold to fit carbs
solex 40mm addhe sidedraft carbs* (just for test fase)
looking for some 45mm webber dcoes or solex mukini's
smsp header? 4-2-1? looking to run a full 2.5 exhaust with smsp 300 cat and 18" resionator (i been reading there thread in the all motor section)
direct port nitrous setup tapped into runners on custom manifold (shooting for 75 shot)
dont know what to do for cam gears. if i have endyne do the head, ill prob use all ther internal head stuff. if not prob crower

Block
b20b*
sleeved to 85mm
92mm eagle crank? Crower?
eagle long rods
pistons? endynes rollerwaves?
not sure with the crank/nitrous and redline ability, should i got with a compression rating in the 12's?
block gard?
Block Girdle?
mostlikely 7lb flywheel (prob get clutch and flywheel as package)

Transmission
90 teg rs tranny*
obx lsd (i dont really care about the axil problem, i think for the money ill give it a shot

Engine management (or lack of)
no ecu (carbs)
hot rod 21 circuit wire kit*
cbr coils*
msd dis2*
autometer oil pressure guage*
autometer oil temp guage*
autometer coolant temp guage*
a/f ration guage?
wideband o2 sensor?
is it ok to run no thermostat? (i have dont it before but dont see the use for it witout an ecu, fan will be hot wired
10 gallon fuel cell
fuel pump?
still trying to work out the distributor thing to get the timing correct with the coils

Brakes and suspension

upgraded to full 89 sei accord suspension/brakes w/ rear disc
ss brake lines
90 teg brake booster*
90 teg pedal setup*
90 teg clutch cable*
90 teg speedo cable*
aem big brake kit with modifications to fit*
suspension tec 2 in lower springs*
tociko blue shocks*
new ball joints*
new inner and outer tie rods*
new bushings*

open to any suggestions. plese dont be gay or post usless info. i know alot of people dint like the chasis or what i have done to it but i dident want to build my eg and be in the same crowd

adding some car pics, will upload motor pics later

there where pics here but 3geez.com went down and lost them

Re: adding some car pics, will upload motor pics later (h0ndavtec)

wow. looks... different.

I have to be honest with you.... I am not feeling the prelude conversion on that!!

most people dont like it, it needs a lil tweeking but hopefully when i am done it will look a lil better. i thred on a 1g integra front lip and a black momo plate and it broke up some of the blue, looks a lil better just waiting on a ne cf hood with the frille

Back to the engine stuff

i actually have a stock b18a1 i am using as a mark up motor for the carbs, the manifold, mounts, shift linkage, axils ect. everythnig is going to be pretty much custom. this was i can get all the wireing, and engine management dont while the b20 is being built.

Re: Back to the engine stuff (h0ndavtec)

Re: Back to the engine stuff (I Expletive Your Sister)

I wanna see the motor setup. The car is kinda ugly.

more pics

here os my b20b head. i noticed this head kinda looks like it was some how oil stained, i never really seen this before on any of the heads i have pulled apart, any1 know what happened?

here is the stock b20b crank. it has spun a rod bearing. i am not planing on using this but is it savable? any offers?

here is a close up of what the crank did to the block with all the heat

Re: my b20b dual sidedraft carb dpi nitrous build (h0ndavtec)

I'm a fan of keeping the OEM look on any car... but kudos on trying something different on the build.

Re: my b20b dual sidedraft carb dpi nitrous build (unbanned_evosol)

Sounds cool aside from the no ECU thing.....why would anyone want to downgrade and run with carbs is beyond me. You will never get 250 reliable whp without being able to tune the thing properly.

Re: my b20b dual sidedraft carb dpi nitrous build (nfn15037)

i am defenatly buying the p8r head

why do you consider the carbs a downgrade?
have you ever seen any1 setup with them on it?

where in boston are you from and who do you know, i am looking for a good machine shop to do some work for me

now why would you say some stupid shit like that, keep your negative comments to yourself.

now why would you go against someone else's own opinion....you post pics of your car, then you have to take the good wiht the bad, and right now dude is taking the bad just fine i believe, without your help

but as for the setup...how are you going to run the CBR coils on the SCI? I thought you needed someitng like a DIS 2 and run wasted spart, or the DIS 4 to run them?

and i'd not consider them a downgrade, carbs make more power than EFI

How do carbs make more power than EFI? I guess F1 and CART should switch back to carbs then, eh?

I have seen plenty of setups with carbs, mainly non-Hondas and most all of them are now running EFI. Why? Because it allows for much more accurate spark and fuel control.

PM me for some good machine shops around.

kinda wierd but if thats what u like, then its all good https://honda-tech.com/forums/images/smilies/emthup.gif

carbs make more power, PERIOD. Fuel atomization

if this car is going to mainly be a WOT car...then carbs are the way to go with n/a or nitrous

carbs don't make more power ant if the fuel atomization is better than why does it use more gas??? you dont want a restiction in your intake system and you want precise fuel and spark!

i havcent figured out the mds/coil thing yet, its going to be hard

What motor setups have two you made more power with EFI than you made with carbs?

I like carbs. My S10 (with 350) has given me new apprecation for the simplicity and power of carburation.

https://honda-tech.com/forums/images/smilies/emthup.gif for doing something different.

Don't know where you're at in MA but Jimmy at Britton's in Beverly does EXCELLENT work and very very reasonable prices.

one question: why an OEM clutch? or is that for a different project?
