ok so I've seen a couple videos on Streetfire.net that have guys in the honda sections with "B20s"

Now i know exactly what a b16, b18 are and I've seen a few b19's for sale on craigslist. But unless people are boring out the cylinders more on integras even more than that i wanna know is the b20 from a different car? or is it just a bored up integra motor?

Quickie Version: B20 engine? Whats it out of?

Never was a vtec, available in early preludes

 
Rep Power: 0

they don't make a b19 what I meant was that there are people who bore there integras out to 1.9 liters of displacement, thus they call them b19's



in regard to the first response


The early gen preludes has b20s? **** You learn something new everyday. I wonder if you could put a vtec head on it and have vtec?

B20 VTEC is basically 1stgen CRV block with B18 head.

there was a B17 VTEC though!

for the list I still see its missing the honda pilot though on the v6 list.. but very useful could be a sticky

 
Rep Power: 278

Also, missing the new civic engines, I believe its R18A1?

Thanks for the list. Very comprehensive.

b20's are from the honda suv's

 
Rep Power: 0

Yes you can put a v-tec head on a b20 block....it is a swap alot of people do in hatchbacks

 
Rep Power: 360

u could also do a b16 head no? but to get the most you would get a b18?

 
Rep Power: 0

Small differences but basically the same power.

 
Rep Power: 360

thats what i figured!

 
Rep Power: 288

wow the d series line was older than i thought, maybe thats why its buletproof, the auto tranny however is another story.

 
Rep Power: 0

the b20 is a great motor out of the older preludes and CRV's. the b20 is great for N/A, but im not going to say the same for boost. now the LS teg motor is a great boost motor.

 
Rep Power: 0

I think it is so wrong 7thgen cant get b motors

 
Rep Power: 319

Before someone asks, no B20's in the old Ludes are not compatible with ANY other B series engine.

And that list is missing a few engines. Like the D15, non-VTEC engine in the 92-95 Civic dx/lx; B18B in the non Vtec teg, but I guess I'm just nit picking

 
Rep Power: 338

a bit off topic, but talking about Preludes, is the engine code for the Si and S models the same? One was carburator and the other was injection.

 
Rep Power: 319

yeah, I think the twin carb one was A1 and the FI one was A2 or something like that.... don't take my word for it though.

I had had the twin carb one

One a worthless Honda trivia note, the Honda Prelude was the last car to be sold in the US with a carburator.

 
Rep Power: 0

wow wait a second. are you saying that the base model prelude is carburated while the type sh of the same year is fuel injected?

 
Rep Power: 319

For a few years, yeah.

 
Rep Power: 338

actually, to the best of my knowledge, the 3rd generation Prelude (the last generation with flip up headlights) had the S model and Si model. S was carbed and Si was FI. Type SH was on the 5thgen only wasnt it??

 
Rep Power: 0

i just did some research and found that the last generation of preludes (2001 i think?) have no difference between their base model and type SH. both are listed with matching specs...whats the difference?

BTW

my source for this comparison was vehix.com

 
Rep Power: 319

They are the same, the faster one doesn't have a badge, but just a sticker that DOHC VTEC.

I believe the SH had a clutch pack LSD that had something like 25-30 clutchs. It was a rather scary tranny.
