would this need to be engineered??

just a quick question basically out of curiosity, would one need theyre gtfour engineered if they decided to ditch the ct26 for smaller twin turbo's?
thanks for the response in advanced

anything that yeilds more power then stock standard i think is the rule, but you may need to conferm that somewhere. so anywhere when you get an increase in torque or HP you need one to conferm you brakes are up to the job.

With respect to turbo's, maybe more power at the same boost??

Rind some people around and ask, don't take one answer as i feel some people will say yes to get the money and not actually do anything. So get more then one opinion

With Victoria if there is a power increase of more than 10% over stock power then it requires an engineers cert.

that would not be the same as just boosting to some crazy levels would it? does 60PSI need to be engineered????

I think the engineer would be less concerned about increased power outputs & more concerned about positioning of said turbos/exhaust components, routing of multiple dump pipes and oil & water lines and proximity of these hot bits to surrounding components and flammables.

I've seen it done before, but twin turbos on a 4-pot - why?

thanks for the info guys, i spose i will have to make a few calls around and find out if any1 local would be willing to engineer it and such.

mrshin, i personally feel there is an advantage to be gained. either way, its different, and if u never do anything different, you never advance your knowledge or skill.plus ive always wanted a twin turbo gtfour

lol good idea or not ive always believed 2 turbos are better than one lol

bah
2 turbos are twice as many things to fail, twice as much piping... suitable only for V engines (imho

)

I have found twins never really seem to give as much power as a single one, but i still wouldn't swap my twins out for a single, love em too much

Twins are also meant to spool faster too but mine spools at 3G which is about where my mate 180sx does, so i don't think they help that much, i just like saying its twin turbo, everyone gets excited because they don't understand it makes little difference

i think the bigger engines can benifit alot more from a big single than small twins...i also feel a smaller engine can benifit more from tiny twins than a moderate sized single...although i may never find out, i may have been offered a dirt cheap gt28...ill keep yas posted if i decide to go the route of the twins...but at the moment just replacing my dead single with another single is looking alot less time consuming and costly lol
