Will my early B16 crank fit in any B20 block? I have a b16 from an xSi integra, and I'm wondering if there is any B20 block that the crank fits in. I'm sure i know the answer already, but this may be interesting.


EDIT: WHAT ABOUT A DART BLOCK???

 

that is a stupid question, there would be no point at all in doing this. dot waste the time or money

 

THAT is what I expected everyone to say, but there is a point to it. I want to know if it would fit.

 

yes

 

77mm stroke!
DART Block? yes.

Think about the possibilities here: use a short stroke, with a long rod, on a max bore Dart block (remind me of the max bore 87mm or something???).

edit: I ASSUME THAT YES MEANS YES TO BOTH B20 AND DART BLOCKS.

 

yes

87 max, yes, still a dumb thing to do

 

i say just let him do it and if something messes up thats on him

hahahaha, what is there to mess up? Put the right rods in it and it will be great, just think about the possibilities.

^^^
plus, if you bore to 87mm thats your last chance, when you wanna rebuild youd have to resleeve. 85mm so when you rebuild, you can just rebore to 85.5mm, then 86 then 96.5 and so on...
Boring to 87mm is also retarded.

 

hes probably thinking FI. NA, gimme stroke... on paper it seems to make
sense to de-stroke a motor and add boost. alot of toyota tuners have had
similar success with the MR2 I-4 to the effect of large HP numbers. I dont
have any first hand understanding on how a boosted motor wears. I can
only imagine that under large stresses, the cylinder sleeves would ovalize
sooner based on the amount of pressures inherent. Im not sure what he
plans to do, im interested in any combination and how it would ultimately
work. My question to him is, is he doing this because he thinks it will be
cool, or because he is following a model that has been successful in the
past...

Saying it was dont in the past is a mistake, it is done every day. I just have not seen it in this application.

thanks for thinking.

 

oversquare engines breathe better under boost inherently... thats what my first instinct was of what you were going for. most boosted engines built that are factory motors are oversquare in nature. honda is typically square or undersquare on its I-4s. I love the K20a2 for that reason... 86x86 is a beautiful thing... and stock. the closest thing to that is the B series 81/81.4 B17a... drop in 81.5 pistons and you are there. hehe. I dont know all the benefits of engine building... I have read this and that. I have an ITR block in my GSR and like it just fine. making it square would take alot of work... 87mm?... YIKES! holy frankenstien budget batman... if you are NA and reducing your stroke... I dont understand that reasoning.

 

I seriously doubt that I can afford to do this anytime soon, as it would require me to purchase an extra vehicle on top of money limitations. ON the other hand, I may be able to just put my B16 crank in the B20 and use a custom rod just to get started on the project and find out what problems I may run into. Over square is not the only thing I'm thinking of. There is the added bonus of the more favorable rod to stroke ratio, which has been something I have thought about since 1998 when I read an article in Hot rod magazine about a destroked 400cid SBC. I know I'm not the first to think of this, and don't care to be. I think I may have said too much, as people will argue with me now that I have opened my mouth, so I'll shut up now. I really hope you guys are right about the B16A crank fitting in the B20 block. I know there are some differences in B16 cranks and B20 blocks, which makes me wonder Does the b16a crank fit all styles of B20 or what?

 

you dont need a rod stoke ratio that high! i knew it was comming to this...let me guess.. you wanna rev to 11k+!?! and your gonna do that on stock B20 sleeves?!? and what cams are you gonna use to make power up there??? at the very least you should use a B17a crank!

you are wrong

EDIT: sorry I was thinking about this, B17 cranks are not the easiest to come by or maybe I would try it. I have seen the same guy crawling all over the classifieds looking for one for a long time now. Also I really don't care to rev anything on 4 wheels to 11k or 12 or whatever else you can think of to flame about. This is so typical...

ok thanks for explaining...change your name...your making mine look bad....

 

So a rod similar (sames specs, maybe not a factory rod) to a B16B rod would work with this kind of set up right?
