b16a vs b20 crv
 

sorry for some stupide questions. and thanks for answering
what will be the safe boost for the stock internals of each motors b16a jdm and b20 crv . my fuel managment is safc with 450cc injectors. and my turbo is t3lt4e a/r 50.

and what will be the maximume hp at that maximume safe boost at the stock internals in both motors ?
iam still destirb which one i buy :6 ??? >:(

Re: b16a vs b20 crv
 

B16a would be safer B20 could only handle 8psi 250-300 hp range

Re: b16a vs b20 crv
 

since its a jdm b16a, you should be able to push 500hp at 30psi!!! :o

seriously go with what Loserkidwac said.....although theres always the option of buying both and putn the b16 head on the b20 and have a b20vtec, but you would still want to build the b20 block before boosting high!! that ---- would scream!! stock b16s can handle quite a bit of boost, probably around 15psi, so youll be in the 300hp range as long as you have a good tune it should last.

Re: b16a vs b20 crv
 

it is hard to me to bulid the engine because my country ( EGYPT ) has no internal or even turbo accesories. i bought mine from ebay. ok i will buy the b16a jdm and turbo it . anyway thanks alot for your answering

85mm piston
ported to ---- b16 head
uber large cams/valvetrain

Re: b16a vs b20 crv
 

Go with the B16, they are much stronger than the B20's.

Re: b16a vs b20 crv
 

Buy an LS. You'll hate not having torque with the b16. It'll be cheaper to just get a b16 head and then a ls block and do it that way. At least you'll have SOME torque.

Re: b16a vs b20 crv
 

If you buy an LS swap you will have a shitty tranny, shitty cylinder head, and shitty cams. He is planning on boosting, so torque really isn't that big of an issue, too much low end torque will just spin your wheels. Go with the B16 swap and then swap in an LS or GSR block later on. I would also upgrade the B16 cams to GSR or ITR as well.

If you want torque go get a RWD V8 car...

Re: b16a vs b20 crv
 

Haha, how is the ls a shitty tranny? Just because it has longer gear ratios? ::)

Did you not read the rest of my post where I told him to do an lsvtec? ::)

If you want torque, you want a fast car

Re: b16a vs b20 crv
 

I saw a destroked d15 so you can rev to like 12k

Re: b16a vs b20 crv
 

Listen noob, your not going to win this argument. The LS tranny with an LS/Vtec that revs to 8.5k is going to be so long you will be going 110mph in 3rd gear. That's going to make your car accelerate slow as ---- and it will just suck ass (I rode in Dave's car a long time ago with an LS tranny and in it and I could jack off like 3 times in between shifts lol). You want to keep the revs up as much as possible when your racing, thus why I say get a short geared tranny. Starting off the a B16 swap will just be easier, then if you really feel the need for more torqu you can just swap in a 1.8L block later.

Here use this and learn something buddy... http://www.autocrossing.com/cgi-bin/gearcalc.cgi

Listen noob... hahaha. I'm not here to ---- talk, just to discuss.

If you're going to be making any real power, an LS tranny will work just fine. Yes, a b16 tranny will accelerate faster (no ----!!!!1111omg), but I'm a drag racing guy and don't like to shift into 5th going down the 1/4 mile. I think you spent too much time on H-T?

Re: b16a vs b20 crv
 

What do you call real power? 300? 400? 500? Dude it all depends on the size of your slicks, how high you rev, etc... For the majority of us an LS tranny will just be too long, especially if your using a big slick and you will be if your making a lot of power. You won't need to shift into 5th with a B16 tranny if you plan your setup right.

I think I hate the LS tranny so much because it's very similar to my gay D-series tranny, 3rd and 4th gear are long as ---- with my Y8, but I don't have any other options unless I make a custom tranny.

Re: b16a vs b20 crv
 

I like to think of real power is anything that can get your car into the low 11's. That could be 300, 400, whatever.

You're right, there are different ways to achieve the same goal. Smaller slicks with the ls or bigger slicks with the b16.

I'm just trying to say that for a "street" setup (drag radials, etc), I like the LS ratios better with boost. I've found that with a smaller turbo (which most people run here), you tend to make boost and spin the wheels a lot easier with a shorter gear ratio. I've had good luck with the LS ratios, but I guess that's just me. I'm an underdog kinda guy ;)

Did you buy a Bseries yet?

Re: b16a vs b20 crv
 

If you spin wheels you should work on your traction (LSD, tires, suspension, staged boost controller, etc...) not get a shitty LS tranny. ;)

No I haven't went b-series yet. I'm working on it.
