Your thoughts,

While riding my bicycle home last night I had a brain wave, whether it being from lack of oxygen to it or something.

I am lead to believe (from information in this forum) that the series 1 turbo cannot be safely boosted above around 12 psi. This seems to be the weak point in the engine system to allow more boost as the usual way to increase boost would usually be a larger or hiflowed turbo. Would it be possible and economic to add another series 1 turbo (as it is relatively cheap 2nd hand) to the system so that both turbos do not have to work as hard to increase the boost to say 18-20 psi? Can the internals of the engine handle that?

Obviously, the following would need to be in place; larger intercooler, air intake, exhaust, upgraded fuel pump and injectors, and an engine management system.

What are your thoughts on this system, possible costs of the added turbo only, and any other constructive thoughts?

Mike

I think what your thinking of is like the system that those race trucks use where 1 turbo feeds boost into the 2nd turbo's intake thereby increasing the final boost the engine recieves, really wouldn't work on stock R33 turbo's though, and not practical for a street car.

Another idea would be to setup a 2nd turbo after the dump pipe of the first so that both turbo's recieve all the gas flow of 6 cyclinders, hence no extra lag but double the airflow, similar to the Supra twin turbo.

Yeh,

Like I said, it was one of those thoughts that may not have any substance as there was a lacking of oxygen from riding my bike. Just a thought tho'

A 4dr GTR would be great as the cars I buy are required to have certain criterias to be filled (due to the wife's demands) and 4 doors is one of them. Luckily boot space wasn't, but now is. Looks like this cars here to stay.

You can get 4 door GTR's but they cost a bomb. If you're after more power, just sell your old turbo for around $500 and buy a new Garrett for around $2500. It'll work out to be around the same cost as adding another turbo (assuming that's even possible).

Also, for some reason insurance companies don't like twin turbos put onto cars that didn't come that way from the factory. My insurance company don't care that I've got an aftermarket turbo on, but they wanted to be sure that I didn't put a twin setup on. They don't actually care what the single turbo is though! Can't wait until I can afford a T88 ;) For some stupid reason they seem to think that going from single to twin turbo makes it insanely powerful. I didn't bother telling him that it's often the other way around.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
