Hey guys n gals

Just wondering how much power a stock gtt triptronic gear box can hold without going bang. I've done a few mods and am about to up the boost and am just wondering how much power:

A: I will have with these mods aprox

B: How much power the stock triptronic can hold

C: how much more boost should i wind in.

Mods so far are pretty basic

FMIC

turbo back 3 1/2 inch zorst

pod

Curently running stock boost, but looking to run around the 12psi mark (stock turbo)

Sorry if these questions sound a bit newbie, but i'm still a bit new sto skylines, i'd always been a 180/ SR20 person lol

I killed mine at 228rwkw. I went to the track a lot. Heat kills them so do a couple of things. Be very careful when it's cold - no boosting or highish revs. It takes longer than your engine to warm up too.

Put a transmission fluid temp guage in your car. Cheapest safety device ever. I just used an oil temp guage and plumbed it into the send line to the transmission cooler. Keep an eye on the temps and don't let it go over 100 degrees.

Another thing you can do is a valve body upgrade from MV automatics in Adelaide. About $350 plus fitting. You take yours out and send it away then get it back 2 weeks later and refit. I did it myself in my garage without much knowledge and it was a c**t of a job but it was possible.

The valve body increases the speed of the shifts which decreases the heat created.

You could try putting Redline Racing ATF in. I put the High temp ATF in but a, it was too late for mine at that stage although I didn't know it at the time, and b, I should have put the racing one in. The racing one has no friction modifiers and every other fluid out there does. The friction modifiers create slip to make the shifts comfortable. Slip = heat = death.

Also I don't believe you need to replace the standard R34 auto cooler. If any R33 owners are reading this - you do need to replace it.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
