twin turbo bseries

[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

Dont know why it is so hard to turbo a b-series. Never knew it was so hard. Thought those engines were bullet proof.

It is hard to twin turbo a be series because it would have only 2 cylinders powering each turbo. Unless ur b series has a displacement of 5 liters then twin turbo is up ur alley. Why? Spool time will be to far up the RPM range unless u have a small as t1 turbo or something. The exhaust from 2 cylinders isnt powerful enough to power a turbo. u see what i mean?

turboing a teg isnt the same as twin turboing a b-series. First of all turboing a teg involves one turbo and twin turboing a b-series involves 2 turbos. Plus a teg is a b-series... b18s.

ECU- Engine Control Unit...*mess with Rev limiter, top speed, etc... i think
FMU- Fuel Management Unit... I think
Stand alone- Computer only for that reason... i think
Race chip- Ebay... i think
Piggy back cpus- not sure.

Some stuff that i kno but i aint no expert at this.

It isn't that difficult to turbo an engine. That is true if money isn't an object. You can turbo anything if you have money to put towards it. It i true that bseries engines are strong. Especially the B16A1 and A2. Considering these have almost a perfect rod/stroke ratio. You can turbo any engine as long as the compression is low enough. These two motors as well as most B Series are a little high strung because they have to be efficient naturally aspirated engines.

A good compression ratio for turboing would be 8.5:1. Some nice strong pistons, upgraded fuel management, and some better timing would make this application possible.

You can twin turbo a car, but that takes a lot more thought. You can even twin turbo a b series. I believe Sports Compact Car has a project civic they plan on doing this to. Anyways, the turbos could be in a linear or bi-directional setup. For instance, in a linear you could have a small T1 turbo spooling a small amount of boost into a larger T3 turbo. Turbo lag wouldn't be as great as if you had two large turbos. The bi-directional method is what is in common use right not by big manufactures like Audi. Taking the small turbo and large turbo idea and plumbing both into a common tube before the throttle body. This application doesn't have much lag because the small turbo is already spooling before the big one begins spooling.

Some misconceptions, but turboing is possible. It is just a matter of $$$$

it really isnt hard to turbo a car. just a matter of time in tuning and the right supplies and combinations i would go with single turbo itf you are intrested in turboing a car with an LS motor (preferrably).... ohh yeah and a FMU is fuel management unit you hook your fuel return line to it and it will shut off the return fuel going back to the fuel tank and send it all right into the injectors.. a simple way of fuel management

Twin turbos on a four banger are COMPLETELY usless.

Of course they are, the question was are they possible. The answer is yes, twin turbos are possible.
