CRVtec??

[94tegRS]

ok, I put up the post a couple days ago about the b16b or the b18c1. I was thinking about how much the GSR engine build-up would cost me and started to think of CRVtec instead.

but is it a huge problem that the b20 has no oil squirters like the vtec engines do? can you put them in.

if not then could I get the b16a block and get the stroker kit from crower for 2.1? liter of displacement, so id have the squirters

no the fact that it doesnt have oil squirters is not a huge problem. in fact if you know what youre doing, it shouldnt even be a factor in your crvtec buildup. ill tell you why. the only reason for the oil squirters is to cool down the pistons when the vtec engine revs up to its very high rev limiter. so any non vtec does not have this feature. but its not necessary especially with the crvtec. see this hybrid is able to generate so much power at low rpm's that revving past 7800 is a waste of an engine. plus revving the b20 block past that spells bye bye to the block. so when you build this hybrid, just make sure to build your cylinder head and exhaust system to achieve power at lower rpms then the high revving vtec engines do. this could simply mean staying with stock cams (type r cams are still ok too) and lowering the crossover point just a little bit to not ruin the power curve but to bring the power in a little earlier. then youll get all the power you will ever need before you hit 8000 rpm and your block willl be safe. i dont think it is possible to put oil squirters in either. never heard of it done and if it could be done it would require some serious custom machining.

about the 2.1 stroker, you have to understand this is not a bolt in and go kit. to make a 1.6 go to 2.1 liters is not easy. i dont know about the kit but im assuming it comes with a new crank, rods, and pistons right? that is a typical stroker kit. anyway it has to be close to that, but you have to understand something. for that kit to work you would have to clearance the crank case to make that big crank fit, which takes opening up the whole engine and machining it. this is a lot of work. and depending on the pistons you may have to bore the block as well, which is a lot of money because of machining just like clearancing the crank case. basically this wont save you any money and could spell disaster for your engine too. ive never heard of anyone using this kit and from what i know of stroker kits, they dont work well on any engines except for the VW aircooled beetle engines. even those have their downsides.

tell me what you think.

ive read on the internet about peole putting the b16 oil squirters on ls's but i dont know if its a bolt on procedure.

what i would do is take the blocks revlimiter, then add 500 rpm, then set your revlimiter to that, but thats just what i would do. say stock rev limiter is 7200, i would add 500 then set the rev limiter, so i would set it at 7700 rpm, but thats just me

i dont' know. isn't the whole fun about honda's is it's high revving capability? hahaha. personally, i really like the idea of the crvtec, but i've heard people having too many problems with it. sure people will always say "if you build it properly, it'll last blah blah blah", but yea. If the b20 was meant to have vtec, i'm sure honda would've gave us one. If you have a b20/vtec that runs 10's, that's FREAKING great. seriously. But how long is that motor going to last? Seeing how this guy seems to keep budget in mind (which most people do), i'm sure he's going to want a motor that'll last him a long time. Sure b18c's and b16's aren't going to always be in great condition, but i'm sure on average, they last longer than the b20/vtecs. just my opinion everyone. hope i didn't offend anyone....

if you read any of my post you would not have wasted your time on your last post. the only reason i know that people have problems with crvtec is because whoever did the hybrid screwed up. sure if i use the wrong distributor it will mess up. if i forgot to lube a cam it will mess up. but thats user error. not fault of the engine. you really need to understand how an engine works to know what im talking about. because as long as all the procedures are followed and done correctly, there is no reason why a crvtec shouldnt last longer then any other honda motor. the head fits on the block, the rest of the internals still work together fine, so as long as the person doing the conversion doesnt mess up, it will all be ok.
and about honda putting vtec on the motor, thats a stupid comment. why would they put vtec in a car not intended to race or needing that extra hp? i mean ever heard of an h22? thats even bigger than the b20 but has vtec. and really the only differences between the crvtec and the h22 is 0.2 liters and oil squirters. they may not have done it like that from the factory but a lot of our cars are not as intended. did the factory intend to have altezzas on all their cars??? did the factory intend to have exhausts put on their cars??? the list is endless. so dont use that argument again. everyones car here is "not as intended by HONDA"

If you read the last SCC or SS mags( can't remember which ) There were four civic with fully built crvtec motors. They were all laying down mid 12's, I think, and 130 pounds torque. If you calculate all the money it would take to do the swap and do it right you could buy a Type R motor with a pound less torque or an H22 for much less so the question is....do you get the bang for your buck???

[Redline_civic91]

talking from personal experience. YES YOU DO!!!! a stock crvtec could easily hit high 13's, seen it before, my friends have, and im hoping i do it to this weekend at battle of imports. i love this engine, so much stronger than most other engines out there, especially in our light cars it makes it even faster. everyone i know with crvtec(about7) hasv't had any problem and they've had them for a couple years now. some are even running nos through them. engine is still cool with it. i would definetly chose crvtec over any other honda engine.

[Redline_civic91]

oh and about those cars hitting mid 12's, my friend has a crvtec with only bolt onls i/h/e/cg and 50 shot of nos in a 95 ex gutted out with mw slicks that runs high 11's with only bolt ons!!!!!!

[edman24]

yah b16ej1 you must understand what bang for the buck means in this certain situation. yes the money put into building a crvtec could buy you a type r engine, but then what? in a crvtec, in unmolested form, each mod makes a bigger difference then the same mod would in a type r motor. for instance, the crvtec hatch i want has an insane engine and pretty much everything done to it. all together he spent about 7k in mods. and hes putting down 250hp and 187 lb/ft of torque, this is to the ground in an NA engine!! now 4.5k would buy you a type r motor. then you have about 2.5k left. assuming youre going all motor, 2.5k in a type r engine would never put out that much power. see what bang for the buck means

[B16EJ1]

I understand what you're saying. I only mentioned the Type R for the torque. If you wanted to hit the strip you could easily put out the same times w/ an H22. I've seen a four door hit 13's with an H22 w just bolt-ons. That's bang for the buck. Same results for half the price.

[edman24]

true, but which will respond better to mods????

crvtec is the correct answer :smoker2:

Its easy budy all you have 2 do is buy the 150.00$ oil line and run it from the oil pressure sencer 2 the back of the vtec head on the distributer side, ther is a hex screw plug simply take it out and put the oil line in thats it( dont rev past 8200rpm) on stock valvetrain

The crvtec swap is cheep and easy:
block=400$
vtechead=400$
gaskit=120$
oil line=150$
ARP studs/fastners=120$
I have the same set up plus turbo kit(10psi)(12psi 4th gear)1/4 mi 12.34 allday 93 EG HB full interior.

Oil line kits are only $25 not $150.

The biggest limitation off the LS/B20 block, in its revving capabilities, is the stock head.

Typical dyno charts for b20/vtec's.

Old thread, I know. Most people do not seem to be aware that the B16 has twenty oil squirters directed at the underside of the pistons. There are the four that tap into the oil galley which are being discussed on this thread and then sixteen more which are oil ejection slots on the sides of the rods. These slots would be very easy to add to existing oem rods or aftermarket rods.

These slots are also used in the BMW S50 engine -- they are differently aimed than the slots that one sometimes sees directed at the thrust face of the cylinder bore.
