B20 vs B18c5

[Gogeta195]

Which is better, B20 or B18C5?

Why?

What are their statistics?

How much do they usually run as far as money is concerned?

as for the B18C5.........
1797cc (1.8L) DOHC VTEC
197hp/134trq

DO NOT GO TO STREETIMPORTS!!!!!!!! I got my engine from them and THEY SUCK!!!! I've had more problems with my engine than I know what to do with. As far as the difference, the B18C5 would be more reliable and have probably more torque than B20 depending on how you build the B20 and what trans you use. The problem with your question is you can build a B20 Vtec to do a lot it just depends on how you build it, but if you build a mild setup it will most likely cost you less the the B18C5. If you want a daily driver I would go with the B18C1 or a B16A there both really good engines and put out a lot of hp. Its up to you though

Stock USDM B20b

Compression 8.8:1
Horsepower: 126hp @ 5400
Torque: 133lb-ft @ 4300

This motor comes WITHOUT VTEC, comes out of a CRV.

Stock B18c5

Compression: 10.6:1
Horsepower: 195hp @ 8000
Torque: 130lb-ft @ 7500

This motor has VTEC, comes out of an Integra Type R.

First off let me start with saying you are comparing apples to oranges here. I dont know if you are talking about CRVTEC or just the plain old CRV motor. Either way, this motor has far more potential IMO when it comes to tuning.

Why you ask? Because the B18c5 is a B18c thats already been worked. Think about it, Honda built this motor to be good out of the box - its very hard (note EXPENSIVE) to mess with perfection.

B20 on the other hand was never really meant to be a tuner motor - however being that Honda motors are so easy to swap, any idiot with half a potato chip IQ for a brain can see the direct benefits. The old term theres "no replacement for displacement" holds true even to Honda. Look at t he torque numbers - 133ft-lbs @ 4300 RPM vs. the Type R's 130ft-lbs @ 7500 RPMS! Your making more torque in the CRV motor before the Type R even engages VTEC! Whats this mean? Even stock for stock, you could take a Type R swap off the line... However if both motors were stock, the Type R would eventually real you in and pass you.

For the price of the Type R swap, you could build a hell of a CRVTEC swap (B20 block w/ VTEC head) or hell turbo the sucker! Either way CRV is the way to go. Let me know, ive got plenty of motors to go around! :smoka:

So what if I took a B20 longblock and a B18C5 head and put them together? How much horsepower/torque are we talking then?

What about cost?

[zippeay]

The head will probably be a lot, why not just get a B16a head or a GSR head, the only difference I think between the B18C5 is the cams. You'll have to research the head not too many places are gonna sell a B18C5 head, but I'll bet your gonna pay out the ass for one

More displacement means more torque, therefore a b20 would have more torque. The b20 also has lower compression and is stronger so it will be more reliable. A B20 with B16 head and GSR transmission would be your best solution.

Alrighty,

So what kind of modifcations do I have to have to make this whole scheme work together? As far as lining the head up with the block, getting the transmission to line up with the block, it all sounds kind of difficult. But I guess this is not something easy. As far as the engine is concerned, what do you think the output hp/tq would be?

[zippeay]

Do a search for CRVtec and there are a ton of sites that go through on how to do it step by step, but if you don't shit about cars I would even mess with it. Find a shop and have them do it, it will cost you more but it will probably be done right. As far as transmitions go all B series trans will bolt right up to any B series block, hence a B16a trans will work B18C will work, got it??? Good luck

[Prelewd]

Neither, just build a B16 and be happy with the money and headaches you save. I don't believe you should frankenstein hondas, they are harmonious the way they are. It's your time and money though.

B18C5 head is a B16 head which is better for valve clearance in a B20VTEC setup, but produces slightly lower compression due to the dome. It has more than just cams over the B18C1 head. It has a mild port/polish, better valves, and improved springs. That's why you get the extra 200rpm on the redline.

Cool I didn't know that, you learn something every day, thanks

alright a B20 would take a type R for like the first .5 sec. of a race stock a B20 is best matched with a B16 head and most common but you have to route the oil which as a couple things of machining to do and the intake manifold produces a little better top end power B20 the sleeves are weak so those would need to be replaces you would need a block girdle which takes a little time to install. you would probably want to raise the compression a little bit cause that compression is not for performance engines on the type R you could also raise the compression a little bit and other then that it is small mod's like fly wheel adjustable cam gears, cam pulleys and stuff like that. the B20 doesnt have very much aftermarket support considering it belongs in an SUV

Are they on crack!?!?!You do realize that,tha tmotor goes for about $1600 less than that right?And 11.1:1 cr?You really shouldn't post shit like that.Sleeve it,new rods,pistons,etc...get the dowel and oil lines machined in and go crvtec,here is a link with more info on a crvtec build up.

:flash: for 6gs you can have a nice awd talon tsi, godamn thats too much for a b18c5 4500 should be the most and thats even too much for a 4 banger
