I recently upgraded the lot from a bitza set up that started with a split dump on the standard turbo, then a front pipe added on later, it was good for 212kw but limited due to the 2 1/2" dump and the turbo at it's limit, mind you after 18 mths @ 16 psi it was still good, then at some stage I noticed it wouldnt boost above 15psi, Dan (3lit3 32) reckoned it was the studs snapped on the manifold, he was right but not quite as I had cracked the manifold as well. So I got a turbo with dump and a second manifold and installed the lot myself, and after a delay due to dyno comps, I had noticed that the cat was only 2 1/2" and with the bigger dump, the exhaust note quite louder as well, Right Price installed a 3" cat and resonator for 400 and I was off for a retune last night, it made 312rwhp/232kw @ 14psi easily, the turbo is a bit laggier but seems to be more gruntier down low, if that makes sense, the exhaust note is alot gruntier as well but the resonator took the harsh bark out of it. my next step will be the injectors, 500cc should do me.

Nice Terry...

I cannot wait to put my new hair dryer to the test...

In the mean time welcome to the 240rwkw club (well close enough).

Its at this stage you will find out how good your clutch really is and its easy to tell how good tyres really are...

I reckon the louder exhaust note comes from the larger turbo....as it has a larger discharge area?? Cause I changed nothing in the way of exhaust parts when I did my turbo and it came back heaps louder! Anyway that is neither here nor there! Good work Terry looks like it would be a fun drive now! I always love reading other peoples modification stories!

I should really write up my story some day! However I think there is a bit more necessary and unexpeceted work to be done before my story is over :O lol

And I hear you on the tyres point Col! All of a sudden I found out my old tyres werent that good! :/

Looking (and no doubt going) really good Terry! 240rwkW should make a nice, quick daily driver, any more and it gets impossible to put power down. I hear you guys on the tyres, after the last bout of mods I did on my old 33, the tyres I thought weren't too bad suddenly couldn't cope.

Nice curve on the graph too, it stays above 280rwhp for a fair chunk of the range :rofl: A set of cams might keep the power climbing for even longer too :)

With this wet weather lately I am finding the grip a bit loose with that extra power, the tyres were OK before, but now, a tap of the pedal gets me spinning too easily :blink:.

what turbo are you running now? they are decent numbers you are getting,very good. :)

The day I got mine back half throttle in 3rd would have me looking out the side windows instead of the windscreen lol...it is fun for a while :(

Nobody can identify the turbo, GoFastBits said it was probably a HKS prototype, it is a BB and has american threads in it, Dan reckoned it be equivalent to a high flow and Peter Woodward my tuner said it looked like one off a Rotar. Beats me, it goes good and the BB spool is goooood.

Yeah it looks to be something equivalent to a GT2535 - SB8032.

These are rated at around 400hp. But the results would suggest a bigger turbo just from the boost you are running...You are probably right about the HKS Hybrid copy thing.

    • 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?
