Hi all,

RE: Nissan 1995 Skyline GTS -t Series 1.5

Can you install a boost controller yourself? Like a hi - low switch? Or can I install a bleed valve? What is the difference?

What else do I have to modify to make this run properly and not dangerously, apart from a boost guage. Someone wrote in the forum that if you boost the car over 9 psi you have to change the computer, Is this correct?

I was looking to boost to around 10 -11 psi. What recommendations do you all have?

I am willing to give it a go myself.

well, you can go well over 9psi in the gtst with stock ECU is no worries! im running 11psi no worries, actually might go up a bit soon! installing the boost controllers is pretty easy, if your refering to making one yourself, then it can work but not guranteed to work as good!

do a search for boost controllers! should bring up what you need

Craved: what year is your car? Depends on your factory ECU.. 95 model and newer stock ECU's seem to be able to adjust better for higher boost without leaning out or requiring aftermarket fuel adjustment.

Its also not a good idea to go much above 10psi with the stock cooler, as you'll probably get detonation. There are many variables and there is no fixed figure, but I wouldn't be going above 9 or 10psi with just the standard ECU and/or intercooler without risk of badnesss.

You can use something like a S-AFC to increase power further, but really once you get to that stage you will need to put it on a dyno and tuned properly.

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
