ok so... is it worth to Turbo Surge the Rb25dett...

have a mate with an s15 thats done it an has had it 4 ages an hasnt faced any problems... my mate with an R34 so far hasnt faced any problems but then again a lil early to say... so basically...

To Turbo Surge or not to Turbo Surge

That is the Question

well... hmmm does it do any damage?

all ive found out so far is that it makes a "flutter" sound.

ummm uses lil more fuel cause it reads the air that comes back in and... possibilities of popping due to running rich... so anything else? i.e. turbo going "BOOM"? because it spins one way an then when u let off the throttle it goes the other... otherwise thats all i know any "bad" results from doing such a thing?

mmmm lets discuss.

^.^

High possibility of stalling when putting the clutch in.

Also good chance of killing your turbo as it only has a Nylon based compressor blades along with much higher possibility of developing air leaks on the various silicon joins/lines.

hmmmm so in other words not a very good idea

lol

turbo's do not spin backwards.

The sound is just the air being bounced off the closed throttle plate and chopping against the air still coming out of the turbo.

My bov is so tight that it flutters under nearly all conditions other than full boost with a quick lift off.

what bov you have???

Some ARC thing, came attached to a piece of pipe that I used to get my bonnet shut after the 30 went in.

The problem was, at idle, it was PUSHING air OUT the bov.. I can only put that down to the undersized turbo spooling from idle.. it wasn't making positive pressure but certainly positive airflow at idle! I mean, you would expect it to be a VACCUM leak at idle (i.e. sucking air IN).

So to stop it blowing air out at idle I had to tighten the bov pretty much as far as it would go.

    • 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?
