b20b w/ b16 head? questions

[90.DB1.TEG]

ok i have a b16a and wanna swap the block out with a b20b with high compression pistons...not sure of the piston ratio....but i have stage 2 crower cams (63402) part #...with crower dual springs (84163)part #.. and manley valves with a port and polish & 3 angle valve job and aem trutime cam gears on the head...would this be a decent setup? estimated hp? and would it stand a turbo in the future with just arp studs and rod bolts..?? thanks for any help!!!

[gunsup0331]

depending on how you set it up you can make upwards of 200whp
hi comp pistons pretty much nix any turbo dreams though

Shouldn't this be in tech.


What comp. are you wanting. Are you going to stay with an 84mm bottom.

[90.DB1.TEG]

sorry this was my first thread other than commenting on others?

[Mr.Burner]

Sounds like a potential 200hp build

[gunsup0331]

got any flowbench numbers for that head? tell me what pistons you are gonna run and ill tell you within 10hp how much itll make

[90.DB1.TEG]

i got the motor the way it is but i got all the reciepts for the parts and some papers on lobes and durations and clearences ect. and one dyno sheet sayin it was 153 WHP.. but not sure what you mean? ima noobie so to say lol

[PENTAGRAM_OF_EVIL]

What does it say on the papers.

[90.DB1.TEG]

^^not sure if it has been bored to 84.5 or what not when the previous owner put the high comp pistons in...i do wanna get the block resurfaced,and honed? but i dont wanna end up havin to by new pistons? (possible?)..the motor already has had a vtec head so i dont need the conversion kit either..and when i get the motor, is there a way to tell the size and brand of piston? sorry all the Qs and thanks again..

[PENTAGRAM_OF_EVIL]

Do you just have the block??? And most pistons I have seen will say some thing on the top.

[gunsup0331]

post up all ur cam specs

[90.DB1.TEG]

^^buyin a complete b20b block on thursday with high comp pistons...or so the guy says...but i do believe him...he said hes not sure what ratio though...he is goin b18b ls/vtec... wondering if theres a way to check the comp ratio? i believe they are aries though

[PENTAGRAM_OF_EVIL]

Have him send you pics. Does he have pappers on any of it.

[90.DB1.TEG]

pics of?

the motor ive seen.. but it still has a gsr head on it.

[gunsup0331]

those arent crazy aggressive cams but should push you to around 200whp with at least 11:1 CR, proper supporting mods and a Locash tune.

[90.DB1.TEG]

i almost think he said 13: somethin but dont quote me on that lol...but 200whp is decent right? and would upgrading from 0bd0 to obd1 and a hondata s300 be worth getting since turbo is out of the question??and what size injectors??and i have a oem fuel pump as well..is a walboro fp recommend on this swap?

[90.DB1.TEG]

^^supporting mods as in rods? or would i be able to get away with just arp rod bolts??

[gunsup0331]

fuel pump no but its not a bad idea to buy a new one since yours is the smae age as the girl im boning
ARP yes

I meant bolt-ons, like a 3" intake with vel stack and good filter, good header or knockoff of a good header, aftermarket or type R intake mani, aftermarket TB, hi-flow cat, bigger injectors, good cams (yours are fine)

13:1 means you are gonna need e85 or race gas.

[90.DB1.TEG]

lmao...haha.... i have a stock throttle body of some kind but its been ported by the same shop who did the headwork but i dont have the papers or specs its just has the same stamp from the speed shop thats on the head..i have a p75 intake mani with a STR fuel rail and fpr reg.. know nothin bout the injectors?? no idea what brand or cc..DC 4-2-1 ceramic headers...3" ebay "cold" air intake with a spectra filter 2.1/4 exhaust with cat and resinator{dam az emissions} and a pr3 ecu with mugen chip..and the head work previously explained.....any mods that should be changed or upgraded?? and i do remember him sayin that he did run e85 but its not needed.. either way i have a gas station near that sells e85...but is there a way to tell the compression ratio on the pistons?? i really wanna know that before i jump into it not knowin.

[Agent Smith]

you can measure the CC's of the pistons to determine compression ratio...

compression test the motor, ditch the POS AEM trutime cam gears, go get a retune from Joe, DONE.

[90.DB1.TEG]

ok i now have got the block and it already has a block gaurd and arp studs which i was happy about but realized that he had a b18 GSR p72 head will the studs work on my b16 or are the different?

i have it all together running in a 90 integra 4dr and it doesnt seem to be that big of a difference than the b16a that i pulled any tips in ways to get more horse power or is there something i can do that would help? called locash but they need me to do the obd1 conversion but too broke now..just lookin for any suggestions for a obd0 car?

[PENTAGRAM_OF_EVIL]

First glad to see you got it together, but if its not tuned i would not drive it at all. And as joe said obd1 and hondata.

[ek9typer]

Get rid of the sorry ass LS tranny .

[Agent Smith]

You need an pbd0 to 1 conversion harness, chipped obd1 ecu, and $450 to pay Joe to tune the car on Neptune.

Also get rid of the ls trans, it kills the power band of any Honda. Get a gsr or b16, if you have the funds add an itr LSD...

[90.DB1.TEG]

eeek.. been drivin it and got jusk under 2k miles...is that bad? and i called built by notorious they said they could chip my ecu for $50..good or bad idea? and yea plan on gettin a b16 cable i blew mine and bought this one off craigs for $60 lol..def plan on converting to obd1 asap though...just wondering how bad is it to drive it. and can i get by with a basemap chip from notorious for now...thanx for the input

[Dead Bird]

have them chip and tune you

[B16-Integra]

Get rid of the sorry ass LS tranny .

X2. Get a B16 or GSR trans

[90.DB1.TEG]

just converted to obd1 with a p28 and locash jumper harness...just wondering what the extra little pig tail is on the harness? my guess is a 02 sensor but im not familier with 0bd1 at all...also throwin a engine light but not sure how to check codes...im sure there is alot of searching i can do but any advice not from some thread over 5 years old...
it is runnin a little better but still need hondata and a locash tune...and a better tranny lol...

[90.DB1.TEG]

would it be safe to drive it as is or is there a cheap and safe way to still use this as my dd untill a tune without damaging anything?

[adam]

checking the codes...
http://check-engine-light-codes.blogspot.com/2006/04/honda-1990-1995-obd1-code-retrieval.html

[rIcHiEe]

x3 on LS tranny get a gsr. on the b16 you will fly threw the gears

[90.DB1.TEG]

Code 20 Electric load detector
Code 21 V-TEC control solenoid
Code 41 Heated oxygen sensor heater
any ideas on how to fix?

[honduh_head]

get the chipped ecu and stop driving the car as is.
