Twin Turbo Honda!!!
Ok, so call me n00b again, which I am. I know not to do it, but I am not really sure why. I mean I know it has something to do with it being such a small engine and all, and that it is 4 cyl. But I really was just curious as to exactly why? I am sure several ******** will call me a dumbass, but whatev I am just trying to learn some ****. I did a search for twin turbo and nothing honda came up lol.

Re: Twin Turbo Honda!!! (naler62188)
dont quote me on this but i would say not enough exhaust flow because each turbo would run off of 2 cylinders....
the question is why would you want to do this?
i have seen one before but i think it was mostly for show and the "because i can".

Yeah, I thought it was something like that. I was just wondering.

lol I know that, I was just wondering if some turbo wiz would be able to explain what the deal is in technical terms. I just always heard "You can't twin turbo a honda" and never heard why.

Re: (naler62188)
you are not going to see many if any at all because there are no really advantages to be gained. think about space requirements, money, and reliability.
putting 2 turbo with a .48a/r on a 1.3 or 1.6 motor is going to be doggish because the motor now has to power 2 turbos, when it had problems turboing 1 turbo before 5500 rpms

Well I havent seen too many v12 swaps in hondas, you can try that too. but in all seriousness a 1.x motor just doesnt have the exhaust energy or volume for twins/ the only 4 banger i would even consider twins on is the ka24de as its 2.4 Litres and makes plenty TQ.

Re: (Boostage)
Twin turbo is a lot more practical on V style engines. Trying to spool even a T25 with .8-1L is rough, not to mention you don't exactly have a lot of room in the front of your engine for all the piping.
With a Honda, you can make more power with a better powerband using a single turbo. The end.

What..?
To the o.p., the reason why people don't twin turbo 4 cylinder motors is it is more complex and expensive with an inferior result. In the book Maximum Boost, there is an ls1 with 8 turbos, done solely as a (pointless) excercise in engineering. A properly sized single or twins would outperform it.

Re: Twin Turbo Honda!!! (95dxsir2)
two t25's or 2 k03's off of a VW would be good for about 400whp
but its would just over complicate things, but would be unique

in my very first post i said that it would be a waste of space, money, and time. the OP then asked for techinal reasons and i gave them.

from experience. cars areN'T the only things with motors that can be turbocharged
think outside the box.
twin GT12's
EDIT: thanks rorik

I Almost took that as signature material..but the one I have now is better..
The reason why I said "What..?" is where did you get those arbitrary numbers?
Obviously, we both know that you can use multiple turbos on anything from a lawn tractor to a chevy big block, they just have to be sized properly.
You sure have your own way of saying things, and some weird ideas. lol. Not saying they're all bad, but, whatever. Like the timeslip having rates of acceleration printed out instead of trap speed/e.t. You are learning things though. I read a lot of your posts and you know more than you first did when you joined h-t.
I still wonder if you can explain the effect on pressure ratio across the compressor with a restrictive intake filter vs a non restrictive intake filter..and why you can never have a filter with too little of a restriction..I'm sure you remember our first "disagreement", where I clowned you over saying you could lose boost with an air filter that was too large..

Don't you mean Aren't the only things?
To actually contribute something, I just remembered that volvo has used (maybe still does) twin turbos on their inline 5 cylinder motors. I know this because I remember a salesman telling me that at a volvo dealer, and I though it was bs, so I went and looked at the car. I was like.."ok..but why?? Why not just a gt3076 or something?" Obviously, the saleman couldn't answer that..

Re: (rorik)
so it started off me just curious, but now i am kind of intrigued. so lets just say for s and g i want a twin turbo B18. What do I do? What turbos(lol) to use? When will they spool and fun stuff like that?

Why? We know you're not actually going to do it, because it would be an exercise in counterproductivity..for lack of a better way of saying it..
I wouldn't recommend it even if someone gave you 2 little turbos.
T'd oil lines/return lines/, 2 manifolds+2 wastegates or a retarded log with 2 turbo mounting provisions and 1 gate, 2 downpipes merged together, 2 charge pipes merged the same way, etc, what a mess!

depends on how much power you want to make and other factors of course.
but just to be stupid im going to say try two GT12's or GT15's i dont think you will choke them because you are using two turbos.

Re: (tony413)
Well I was just thinking about 300 or maybe even a little less, nothing too much(I know I would kill myself ). I don't really want to drop a ****-ton into it but I know if I were to do this it would be rather expensive. I have no I dea how expensive though. I don't know how much alot of **** costs actually. Like how much to sleeve it? idk

you will not need to sleeve a block untill 500whp and thats just my personal preference. i would estimate that you would probably spend around $4K-6K on a budget.
if you can keep the build very very simple and get second hand parts and maybe some free stuff you might get away with $2k-$3K

Re: (tony413)
The only thing about being on a budget is that I want really good quality stuff. But if I could get two turbo and everything I need for 4-6 grand, I'm totally doing it. I don't care if it is counterproductive. I think it would be funny/cool as ****.
