twin turbo honda

[dboi1107]

here are some questions i cant find a answer to.. do any of you know it?

well why is it so hard to turbo b series engines?
what makes it hard to turbo cars in general?
if you can turbo a integra shouldnt i be able to twin turbo some b seris engines?
whats the difference between a ECU , FMU , Stand alone, Race Chip, and piggy back computers?

thanks

1.It isn't that hard. It just takes money and patience.
2.Same as #1.
3.Yeah you probably could, BUT I wouldn't recommend it. You'd have to ask someone else about how to. I just believe it would be a waste because a bigger single turbo makes more horsepower at the same boost level as two smaller turbos.
4.An ECU is your car's Electronic Control unit it controls your air/fuel mixture and all the electrical components of your car. An FMU is a device that changes the fuel consumption of your engine, usually used as cheap way to trick your stock ECU to accept boost. A Stand alone system sorta takes over for the air/fuel regulation of the ECU and allows you to control all aspects of the air/fuel mixture. A race chip I'm guessing just upgrades your stock ECU chip to allow more air/fuel to make more hp. A piggy back pretty much does the same thing as a race chip, but it's plugged into the ECU(and is probably a lot cheaper than a race chip)

you dont recommend it? why not? well let me make myself a little more clear, what i meant was a sequential set up. like a small sized turbo kicking in at rpm lets say around 2800 or so then the fatter one to cut in and take over a lil later thats what i meant, so then it'll be more effiicient and more HP but then the engine probaly cant handle too much any way rite?

Well I guess that could work if you wanted to spend the money on it. And yes, the engine could hold the power as long as your kept the boost around or under 8-9lbs. After that you would have to strengthen your internals.

twin turbos make no sense in an inline 4.

[tran_nsx]

with money u can basically do anything, but as far as a sequential turbo setup in an integra, it's just too much of a headache. why try to play around with two turbos well all u need is really one. there's aftermaket turbos that can create +550hp and this is just from the turbo itself. to help reduce lag just spray some nitrous, but main reason why people don't use a twin turbo setup i bet is because of the amount of room not available. in some single turbo applications, in order for the turbo to fit correctly, the removal of some engine components is a must for proper fitment. hope this helps.

Shit if you want to spend that much money, buy a Supra Inline-6 and rip out your rear seats/trunk than have a welding and auto shop build you an engine compartment and mate the engine and tranny to your rear wheels.

how the hell would you fit two turbos in the engine compartment of a honda anyways. It's a tight fit as it is with just one turbo

Twin turbo's have been done already. It's even on a D16 motor.

well there is about a million ways that you could put two turbos on a honda motor but you just have to do a lot of work that is way it is pointless. So i think if you are wanting to do a twin turbo setup cause it will be different, well be really different and get one turbo and then hook up a supercharge to that. Get that to run nicely and then i will give you a pat on the back

the point of a twin turbo system is to use two smaller turbos so that you reach full boost quicker right. He doesn't even hit full boost till 4000-4500 rpm, so what was the point of doing all that work??? I give him props for the fabrication and everything, but that was completely pointless. Might as well have gone with the t3/t4 and had the potential for some huge power figures and quicker 1/4 mile times.

[doug294]

I agree. A lot of your twin turbo car awners will often opt for a larger single turbo.

alrite thanks everyone i have learned. 4 cylinder not worth twin thanks agian for the suggestions.
