Installed the new engine into the car on saturday and it runs fine. Cars driving and seems to be working good, except.......

When you put your foot down the car boosts way to high, it hit 1.8bar when I put my foot down so have only done it once way to much boost......it drives fine if you dont put your foot down hard and its still got the boost restricter in it so it should only be hitting 0.7.......Any idea what would cause this?

Fane suggestes one of the actuators on the turbos?

Make sure the boost controller is connected..  could be a simple thing like that..

I dont have a boost controller it just runs stock boost through ecu atm. Pretty sure its actuator, am going to work on it this weekend, out come turbs and pipeing again.......

Pretty sure you can see if the actuators are working on the turbs without taking them apart.. you sure the stock boost controller is hooked up properly, I only suggest it as having no solonoid working will cause stupidly high boost pressures.. if not my bad and good luck pulling it apart again.. :cheers:

Cheers

cant believe you got all the way to 1.8

on a new engine?

How about backing off when it passes 1 bar next time, or even better when it just gets over stock boost

This doesnt help me solve my problem......

We didnt know it was broken, just put the foot down, doesnt take much time to hit that kinda boost, i watched it climb to rnd 0.5 bar i wasnt driving dad put his foot down then I told him to stop.

If you must know we didnt know what to expect or to do to fix it really which is why i've posted here. Now we know what to look for wont happen again.

    • 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.
