Hi Guys,

I know ive gone about this the wrong way but I found the turbo I wanted pretty cheap (HKS 3037 Pro s) so I grabbed it, so now I have no money to buy the programmable ECU I was saving for :headspin:

My problem is, once I finish installing the new turbo im not sure what I should do to get a bit more hp but without letting it lean out heaps and detonate and all the other bad stuff that goes with it :flamed: until I can afford to buy a aftermarket ECU and injectors etc. The mods currently are a large FMIC, pod, full 3" exhaust, MINES ECU(came with that from Japan) and running about 10psi, and with that set-up I was running about 190-200rwkw. So at that power the fuel pump would be not far off from being maxed out, right???

So a fuel pump is first, I was thinking a bosch 044?

Now what should I do from here, my thoughts were to get a rising rate fuel regulator and run only lowish boost 8-10psi?

but someone told me I could clamp off the fuel return line to feed the injectors more fuel, but wouldn’t that make the car run like shit down low? Could you rig up some sort of boost solenoid to shut off return line when on boost?

Or add an injector or two running off a sub injector controller?

What would be best or does anybody have a better idea?

As you can tell im not a mechanic, but I am learning. I like to do as much work myself as I can, so your help would be much appreciated :D

Thanks

Sorry about it being so long :wassup:

Hi ....luke, Mines ECU's are notoriously rich and retarded. So it would be be worthwhile fitting it all up and going along to your local dyno shop and having the A/F ratios measured. You may well find it is OK, not perfect, not producing maximum power, but just OK. On the dyno gradually increase the boost until you start to see some detonation or leaness, knock it back a bit on the boost and it will be OK until you can afford a Power FC.

Clamp of the fuel return line, shoot the person that told you that.

Stick the 044 in the tank before you go to the dyno, as above.

Extra injectors, controllers, YUCK. Save up for the Power FC.

Hope that helps

Thanks sydneykid thats put my mind at ease. I did not really like the idea of an extra injector either. would an adjustable fuel reg help get a few more kw or is standard one good enough to do the job? Ill need one when upgrade ECU anyhow, wont I? or not until I do the injectors

Ill slap the guy that told me about the return line tomorrow when I see him :slap:

if you install a 044 pump you will also want a higher flowing fuel reg. ive been told before the standard regulator cant handle the flow produced by the 044 pump which then make the pressure run high at low fuel ussage then when high fuel ussage return to the pressure set.

    • 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?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
