if i just run b20 which is obd2 and it dosen't come with a ecu....>>>... how do i make it run? no vtec head hear. I'm not sure but gust guessing here of the possibiltys:

Parts
1994-1996 teg intake manifold..... can i use 90 to 93
obd1 distubuetor and injectors
ls cable tranny
obd1 ls ecu?
and then convert my car to be an obd1 right?


I already have a B16a1 long block from hondamotorsonline..... but not sure if i want to run b20vtec.... maybe i'll just take the easy way and go b20-turbo(easy 13's)well easyer that b20vtec.... might just sell my b16a1......


please help

 

i have all the stuff you need to make that b20 work, all parts non obd
1. teg dist
2. teg intake manifold with fuel rail and injectors
3. pr4 ecu
4. wiring harness
5. alt.
6. and what ever else

 

soo... what your syaing is that i need all obd-0 parts right?
can i use my STOCK harness or the one on the motor, or the obd-0 teg harness?
what is the pr4 ecu? not familiar with teg ecu... sorry.


sorry i'm sorta hard headed .....

 

you definitely need to do a CRVTEC in that EF. my friend just built an LS VTEC for his CRX. he ran into a GTP in chicago, this guy was going 80 already and pulled away- my friend waited until the guy was like 15 cars ahead and he hit it in fourth gear--pulled the 15 up to the guy and pulled another 15 cars on him. i hear GTP's really open up at 80- the LSVTEC didn't even need to drop into third, just stay in gear and hit it. if you spend a little bit of money for machine work on the combustion chambers and some pistons you will have a fast ******* motor.

 

wiring should just be a multipoint conversion. the b20z has a knock sensor the b20b does not, but if you run a 90 teg ecu(pr4) than it wount matter anyway cause it will not reconize it. you can use almost any teg intake manifold, but i would just use all parts from a non obd teg to make it less complicated. i had a b20z in a 92 hatch bone stock and it was bad ***. if you can find one and afford it just put it in there bone stock and upgrade later.

 

damn that's a good kill..... what cool that your encourageing me to go for the faster motor combo, but i just hate when i'm all done and it doest run right. i can swap motors but never done anything like taking a motor completly apart and buping it together.

But if i do do b20vtec i'm the type that will take my time (really i mean take my time.. like a year or more) and build it right the firts time with only the best or close to best parts. I just want to b20 and use the motor alittle until i feel the time for the rebuild(b20vtec)
just need some help on how the hell to get it running in my car.

 

Actually.. I think if you can get ahold of a 88-91 Prelude ecu.. that would be slightly better for fueling. Not sure about wiring wise... It should be plug and play. The LS I know for sure will run fine wiring wise..

If you have an Si.. Then it'll be plug and play.. if not.. you'll need to do the necessary wiring modification to make it work.

As for the rest of the parts.. It looks about right.

 

1)So i can use my stock 91 si harness right?

2)What did you run? my friend had the same setup and only ran 15.0 flat?

3)The difference between the b & z is just the compression right...so that would mean just the pistions right... everyting else about the motor is the same correct?

 

You can make it run with carbs, but I'm guessing that's out of the question....

 

GTP? grand prix gtp? uh... if your friend was 15 cars behind... I am thinking the GTP turned off "race mode" and was just crusing...

you should be able to use your si harness might need to mod a couple of things, not sure.
i ran like a 53 or something cause i dont go straight i dodge cones(scca solo)
pretty sure the pistons are dif. b20b has 8.6-1 and the b20z has 9.6-1 both have 133 torqe the z has 146 horse and the b has 126. but you really dont feel a dif. between the 2 cause all you really feel is the touqe.
