hi, i am currently getting my engine rebuilt and putting it back into my r32 gtr and need to know if i can put on a set of -7 turbos without changing anything else like ecu, injectors, fpr? the simple reason is i dont have the money to do any further mods at the minute and would like to get rid of the old turbos - the only other mods done to date are ported cast manifolds, cat back exhaust and pod filters

Nistune is the best ECU for what you need. Checkout their website.

yeah i've looked at it but was wondering will the car drive ok with the stock ecu if i leave the boost at factory level for now (the restrictor is still in place so 8/9 psi limit) so i can drive it around for a while before changing anything else

if you havent bought the -7 tubos yet, id swap em for the -9's; new design, more efficient and same response with a better top end.

A mate of mine has a racepace built motor with -5's running the stock ecu until he has enough money for an ECU and it was run on the dyno with safe AFR n Knocks etc.

But best tune asap to get your full potential, power fc is great as its plug n play

I agree, the -9 seems to be a more efficient turbo.

The stock ecu is quite capable of running with those turbos, the question is how much boost u want to run, because it will start to get a little lean in the low to midrange with increased boost levels.... a problem which can be helped a bit if u have an adj. fuel pressure reg. to bump up rail pressure a few psi.

      You guys need to live a little! Nothing keeps the blood flowing like lying under something that could collapse on you at any time! The vast majority of the weight of my car is out of it. There's zero attached outside of the interior of the car. It's pretty much full interior but once I take the front seats out it's just the dash and some of the boot contents remaining. I would guess that as it sits it would be already well under a tonne, even less without the seats.

      You'd be better off digging a pit and standing under it to shoot it.

      Troubleshooting - motor wont turn over

      The easiest way would to be ignore the oscilloscope, grab a multimeter, and make sure all the main connections are right. An oscilloscope will give 99.9% of even technicians so much grief, as they have no idea what things should even look like on an oscilloscope. Which is also even more likely for someone who's first ever major work on a car is this If the battery volts are dropping down so low, the LDV will reboot the ECU, when it does so, it will drop out the start circuit. If this is occuring, the battery voltage should also come back up. Give it a few tests, even simple ones like when you're attempting to crank it, measure voltage from the engine block, to the negative terminal. You might find you've got really bad connections somewhere. My guess is the "new" motor has something like a shit starter motor, at which point, you can swap the starter motor from the old motor, to the new motor. Before I did any of the above though, I'd 100% confirm the battery in the vehicle. Most jumper packs are absolutely useless, especially if a battery has a bad cell for example. Also the new modern "jump packs" if you don't know what you're doing with them, you won't even get them into high current stage. So go back to basics, check the battery, especially with a known good one as a replacement test. Check ALL the wiring, this includes where they're bolted onto the battery, and bolted onto the starter motor. Check all the earth straps are on. Measure your resistances across your earth straps. A good check here is to measure voltage across the earth straps while you're trying to crank it. If you're seeing voltage, you've got high resistance joints! Oh, and once you've done the above, check the battery over again.
