opinions on changing to CRV block for B16A

[J-MuN]

hey guys,
was jus pondering on the idea of changin my current 1.6L B16A2 block to the CRV 2.0L block.. have heard of that idea but dont know much bout it... i'd like more power and was just pondering bout this idea.. have been recommended to go the turbo kit (cough andy!) but was just wondering the pros and cons on changin the block... and the cost differences...

cheers

forget the crv block. pssssshhhhhhhhhhhh!!!!!!!!!!!!!!!!:D

[J-MuN]

ouch.

Do a search... When I looked into it, i was told b20 crank is no good for high rpm, so you will need to source one from another motor. B18C5 crank is best. You might need to run an oil line for the VTEC? Bottom line is get somone who has done it before.

I was thinking of the CR-VTEC motor for my sol, but really the sols are just too heavy for NA. It's not like the mirage at only 900kg odd. IMO the CR-VTEC combination is really at home in the more lightweight eg models.

nothing like a hybrid!good luck :thumbsup:

it's relatively easy to do and requires few parts and should give you noticeably more torque.

BUT there is no way you will be able to rev it out to 8krpm without spending $$$$

ah k...daiyum... wat bout price wise?... gonna cost less than turbo kit?...

I think you will find it is pretty much even depending on how far you want to go with either. Dollars per kilowatt the turbo is always going to be cheaper, but the CR-VTEC has the capability to be alot more tractable than a cheap turbo kit.

in what way?

[PhatSol]

in what way?

By tractable I guess I was really meaning the throttle response and low down torque. A cheap turbo kit means air-air intercooler, non BB turbo, etc... Due to the selection of cheaper components, the lag and throttle response of such a kit would be far from ideal. Whereas the CR-VTEC is free from turbo lag and should have excellent throttle response, plus a significant torque advantage from the extra cubes (till the B16 hits boost).

nothing wrong with the b16 julez..

Comming from a Mitsubishi background of course I have not had much hands on experience with the Honda stuff, which is why I started my first post with "do a search" and used "IMO in the last sentence. Having said that though, I have had my share of "real life experience" with various diffrent Mitsubishi motor combinations. How about, instead of making weak flame posts, you contribute to this thread?

no1 is flaming bud, just making it clear that ur advise is from what you have read on the internet.

so did ur mitsubishi spin sideways when it hit boost?

No problem, I was just hoping you would contribute because I am genuinley interested in what you have to say. I do not intend my posts as advice, only as personal opinion. Also I would like to add that most of the stuff I read is not on the internet, it is in books.

Lol no :p

I never went down the boost path in my own car. From experience with other 4G93t and 4G63t powered FWD lancers it really did not suit my application. I was working on the developent of a NA 4G15 motor (mitsubishi equilavent of a D series). Never finished it before the car was gone. The stroker short motor is still in my garage :(

[PhatSol]

Serioulsy Pornstar, tell us how do you think the CR-VTEC will stack up against an equal cost turbo kit?

[SiR JDM]

Yea andy... fill us in

I know you were considering the mugen b20 block back a few weeks ago over your boost setup..

enlighten us with your experience =]

I personally think the crvtec is nothing compared to a b16a turbo. I've seen 3 of those Frankenstieners with a fair amount of work and they dont even come close to a b16a on 6psi.

That mugen b20a isnt Vtec, and the only reason id take it over a turbo is the special WOW factor that mugen engines seem to create. for street, drag and even circuit, Id prefer the turbo.

I know tinkerbell and a few sydney people disagree with me, but every high powered frankenstein bottom end that isnt built sleeves pistons and rods, end up failing under high rpm. That is my own personal expereience, Ive seen 3 of them fail in front of me.

A turbo is much more reliable, more powerful, and in the end makes more power for much less cost.

Seeing as Chuck (aka ALLMTR) ran CRVTEC in his 3rd gen Civic and produced a 12 second Civic on a budget, I'm taking all these turbo > CRVTEC posts with a pinch of salt. ALLMTR's motor never failed and neither has tinkerbell's, nor have the dozen odd people I know in the US that have this setup. There's a lot of myth around the frank swap and it's based on people not doing it properly.

JMun - PM people who have actually done the swap and get their thoughts.

[pornstar]

or you can see how nicely chucks motor is running in the crx down here and compare that to a turbo b16a.

shall do...thanks guys for your opinions....
