Default ??? LS vs. CRV

I have a feeling i am going to get flamed, but... why you anyone swap and LS when for about the same money you can swap a CRV? The CRV comes with more hp and torque I thought, but maybe i am wrong?? Reson i ask is i am about to swap one or the other, and i don't want a b16 so please no one start in on that.

dunno,

maybe cause most LS/VTEC's get done on integras already with B18's

just a thought?

because the crv is just now starting to increase its popularity.

but its easier to do an ls
there is no such thing as a complete swap with a crv
no manual trannys, cant use the ecu.
and you cant use the stock intake manifold.

1. So do I use the LS ecu if i decide to swap a CRV?
2. Later down the line what ecu do i use if I CRVtec it? gsr? itr?
3. Does the ls ecu "just" work or... does it work well cause its seems that it would be not be shooting enough fuel (1.8 vs 2.0)....or should i just go HONDATA?

I'm not going to get mad, but Tinkerbell doesnt know sheit about engines if you think putting an LS-Block on a VTEC head is the same as a GS-R's engine.
The block is much bigger than than that on the GS-R's head, my friend swapped out his block for the LS and saw a good gain in hp and a massive gain in torque (relatively, 1.8 on 1.8, but it was on the butt dyno )
The issues between the two engine swaps: CRV costs much more, but will gain you more power due to more displacement. However, it's a low compression block, (B20B) the (B20Z) in Japan still has higher compression, but it's still stupid low in performance terms. The problem with these two engines is that they are not designed for high-compression, high-revving applications. More than likely you will swap the rods and pistons and have a 9k+ revving engine, and as many crv/vtec owners will tell you, this engine has alot of problems. I've talked to guys that have simply destroyed the whole setup or had a bunch small problems, you're in a world of **** with a CRV/VTEC if you know little about cars and try tuning it. But than again, many have done the swap, seen massive gains and 0 problems.
The LS block is the engine designed for higher-revving, high compression applications, basically, it's stronger. True, it does not give you the same gains as a 2.0 crv but its hands down more reliable. It also costs 200/250 vs crv's 800/1000 for the block.
You can re-sleeve the CRV-Block, get even more gains and reliability, but for that amount of money you could have a re-sleeved LS block and saved yourself alot of money.
You will of course have to buy a VTEC head for this swap, I would reccomend the B16 head from a 99/00 SI, or a GS-R, but the b16's head flows a tad bit better.
Sorry for the long post, flame away!

I have never personally seen a manual crv. But I have been told by several sources that they do exist, but are very rare.

Oh, and the crv is probably the most expensive swap next to ctr or itr. All those little things you have to buy add up very quickly.

I've been carless for over 6 weeks and am just now starting to see the light at the end of the tunnel.

The LS block and the CRV block are indentical, except the crv has 84 bore and LS 81 bore, so i don't see how you think the LS engine is designed for higher rpms or is stronger.

Yeah, i'm in that same boat. I'm going to buy a B16a2 swap so i'll have all the little crap that I do need. All i'll need to do is swap in my built B20 shortblock after modding the head, sell the B16 tranny for a GSR tranny w/ LSD (should be pretty easy) and i'll probably end up spending less than if I tried to source all the little parts seperately. That's what i'm hoping, at least.....

I've actually read that the crv block has more webbing around the cylinders, or something to help make-up for the loss in cylinder wall thickness. So supposedly, it's actually stronger. z-10 motorsports is supposed to have a block girdle that makes the b20/ls really strong. They can be built strong, just takes different parts.

Yes, there are CRV 5 Speed, Manuals, because I OWN ONE =P

Also, the CRV's Cylinder sleeves are much thicker then the LS. Although the water jackets are smaller
