i know the rmcdaniels is using the 95mm crank

and i know stock honda cranks can handle all the power you can throw at them but seems like it would be nice to have a longer stroke especially if it was a DD just to have some more umph down low

also could someone tell me what the stroke for all the b series motor cranks are? and are they all compatable with each other?

to use the 95mm crank would you have to have some sort of special block?
who all makes aftermarket cranks?

also anyone know eagle's homepage or the homepage to anyone else that sell cranks?

in the vw world there have been a few people that have use diesel tall blocks 100mm cranks and 20v heads to equal what i think is 2.2l basicly whatever 100mm stroke and 83mm bore equals

id just like to know more about honda cranks stock and aftermarket so all knowledge lended this way would be great

 

check out the dart blocks. They make a tall deck block for longer stroke.

Besides that, Not that many ppl use them either because of experience with billet cranks cranking or just exploding.

If you have a well built block it wont hurt just to give a lil bit more boost for the street.

i know the difference between the gsr and ls crank is only around 1.7mm i want to say, but dont hold me to it!

 

When guys are using OEM cranks in their hotrod 1000whp+ builds people tend to see no point in going with some monster aftermarket crank. It's generally a money thing.

I've seen big cranks work great in some motors, but when you're revving to a gazillion RPMs to get a powerband the longer stroke is not really helpful.

Comes down to the end user really, I like OEM cranks personally though.

 

It's also a rod:stroke ratio thing as well, that extra 6mm loads everything up in a not-so-happy way.

But like Aaron said, I have 3 LS cranks ready to go...all attained for under 200 dollars lol

That frees up LOTS of money elsewhere

 

its hard enough to get a car making power with a stock crank to give it more torque to add to the wheel spin.

 

say you had a b16 and you still want to rev really high like b16's can but would like more torque what would you do to keep a good rod stroke ratio and add some displacement? what crank will pretty much drop in a b16 for just a little bit more stroke and still keep it with a good rod stroke ratio?b17?gsr? can any of the b series cranks be used in a b16? if so which ones and would keep it so you could rev the **** out of it like you can a stock b16?

 

If I had a B16 that I wanted more TQ from, I'd get a GSR lol

I'm not a massive specific motor guru, so I'll let others answer the different crank deal. But I want to say the B16 is different.

I believe the best R/S ratio was said to be a B17 crank in a GSR? I think it was right at 1.75. But you're already there with the B16, so anything else is technically just hurting you.

Add a turbo to it or something

 

i don't already have any honda just planning on the future

on stock sleeves what is the safest to bore to and what would a gsr motor with the b17 crank equal displacement wise?

i've had a b16 before and i loved it because it felt like it never wanted to quit revving and i would like the same thing except with a little more down low

just wondering if it would be better to just use a gsr with a gsr crank or a gsr with the b17 crank

i wonder what kind of difference you would feel and if the plain gsr could safely turn as many revs as one with a b17 crank with a built head of course

alot of vw guys are taking the 92.8 stroke crank out of the new 2.0 vw and putting their 20v heads on and have a 20/20 but i don't want to lose any revs so im sticking with my stock crank and just getting a head built to the max while still have hydralic lifters if you went to solid lifter you could rev to a max of about 11.5k rpms but you have to adjust stuff in the head all the time and i don't want to deal with that and its about a 5k$ upgrade with the hydraulic setup maxed out its good to about 9k rpms but once its done you don't have to mess with it

 

Being as the GSR had more displacement it would be the way to go. As far as the B17 crank, I don't know the stroke so not sure where you'd be at there.

I take it with this being in the FI forum it's for a boosted car right?

I'm going to go on a whim and say 98.4% of FI setups will see no benefit worth trying something other than either a GSR or LS crank within either B18 series block.

 

definately going to be turboed

what can you rev a gsr with a ls crank or a ls vtec to with a nicely built head?

 

~10.5k

I hope that's enough lol

Note, that's given you have the turbo to pull until there.

 

well thats plenty id be happy with 10k rev limit
if you can do that with that type of RS ratio

whats the max people do with b16's?

is the crappy RS ratio on the d's the reason you can't rev them? what can you rev a built d too?

 

I took mine to 9500 last season, no problems. However I'm sure there was more strain on things.

I know nothing about B16's really, IMO they are worthless to make power on haha

What turbo are you going to run?

 

its going to be a while im just planning for the future if its a d i'll probably run the 50 trim .48 hotside just because i could take it off my beetle and put either a s258 or s362 on the beetle

if i could find a crx or hatch or da with a gsr or b16 swap which is ideally what i want i may still use the 50 trim but swap in a .63 hotside or if the 50 trim isn't around by then the smallest ill put on a b series is a 35r or BW or precision non BB equivalent because the honda's gonna be my daily and the beetle is going to be my weekend warrior that way i could get the honda tuned for race gas and have some fun at the track and on the highway occasionally and id still have my beetle if i cracked a sleeve or broke something

i know it would make since to swap and have the honda as the weekend car the beetle as my daily but the beetle is very sentimental to me
i was raised by my grandfather and he passed away about a yr and half ago and its the last thing left from him of much worth so............i don't plan to ever get rid of the beetle

with the honda as a daily i'll be happy with 300whp out of the 50 trim on pump and i could do that with whatever motor is in the honda i pick up.............it would just take more boost to do it with a d

id eventially like to get my beetle up to 5-600 whp on race and then start saving up to do an AWD conversion.........can you say sleeper 600 whp AWD beetle haha

have you ever drove a turbo d with vitara's? i just wonder how it would be as a daily with such low compression can you do anything with a vitara setup to raise the compression do they make rods to up the CR to about 9:1 or is all you can do is deck the head and block to try to raise the compression?
im just thinking if your driving around with 7.5:1 CR its gonna feel like an absolute turd until your in boost

before i had my beetle i had a 99 SI and that b16 made me fall in love with high revving honda's......my grandfather was getting himself a turbo s beetle and asked do you want to trade your honda and get one too and i couldn't pass it up i love my beetle and since the model we got has the best manual tranny that VW or audi makes it makes for a good starting point that and a motor that you can put a set rods in it and its good to 5-600whp they come factory with forged mahle pistons people have made over 700hp on stock pistons its the only real major difference in a normal beetle and the one i have is the six speed tranny, that is the same as whats in the audi TT's...........the only BAD thing about the VW engine is the heads don't flow for sht and the cams are SUPER mild in stock form so headwork is uber important just for example a fully p&p head worked to the max will flow about 10cfm better than a stock k series head............sorry for the rambling

what do you think of this plan for the future?

 

i've also been thinking about trying a holsets on both cars since i can get hy35's and hx35's and the he351vgt for about free

if anyone ever makes a vgt controller for the he351 im definately going to try it out

 

I'm at work so can't really swallow all of that right now, but I can comment fast on the Vitaras.

FJT makes a longer rod to up the compression for the vitara piston, but I'll shoot straight. Start with a B-series lol

 

when you can try to read it and tell me what you think alright?

so you wouldn't build up a d for cheap if all i was wanting was 300whp or so on pump? i could do that cheaper than just the b swap let alone add on the turbo kit and what not after the swap

 

I have an LS crank in my gsr bottom end and I love it. I have revved it pretty high 10K rpms. Mine is a racecar that sees very limited street time, but i really do like the little more tq, a bit quicker spool, and a little more power i got from my old setup.

i dont see the need for a 95mm crank, when we have 200 dollar or less oem cranks available that can get you a full 2 liters of displacement

i dont think there is any other crank that will drop right in a B16 other than a B17, but im sure you have to use the B17 rods with it, you can use whatever pistons but the rods have to be from the B17.

 

big turbo = revs for spool and HP. Better off going with a short stroke motor for the better rod ratio to get peak torque at high rpm where you want it.

Displatement through bore is a better option or get a tall deck motor from dart
