Hi Guys,

I just bought my first Skyline and now I'm agonisingly waiting for it to arrive. (R33 GTS-T Type M)

Now I know how cars work but I don't really know much more. I'm not a mechanic.

What I'v been thinking lately is

How do I icrease performance without using bolt on mods?

Such as bigger turbo's, increase boost, intercooler etc etc.

Basically, I want to slowly build my car as genuinly fast and the first things I wanna do are make changes to the inside / strength / power of the existing engine and then once the engine is strong enough I will bolt on the bigger turbo's etc etc

The first thing I thinking of is CAMS and possibly head gaskets...that sort of thing.

Can I get a top ten list of non bolt on mods please guys?

I'm also open to people who oppose my point of view and thinking...as I said, I'm not a machanic. (Maybe the engine is strong enough to handle all the bolt on mods straight away)

Cheers,

Sam

As sumo has said, depends on your power target.

the stock rb25 internals have been pushed to 250rwkw time and time again by numberous members of the forumn. If that is your goal, then turbo + support systems are sufficient. A stock motor that is properly tuned will last a long time like this.

On the other hand, if your power goal is 400rwkw, then you'd need to do support systems, turbos + engine work.

K&N Panel filter in the factory airbox.

Full 3" Exhaust (including front/dump/cat pipes)

You can/should do those to start with and you won't even need to lay a hand on your motor. Expect those to increase power by around 30% to begin with.

Absolutely no point in modifying anything inside your engine if you don't have a larger turbo to bolt on as well (and it sounds like you are far from that) and even with a larger turbo you most likely won't need to modify anything at all inside the engine.

The engine is strong. Strong enough to go well into the 200's RWKW before you need to do anything other than bolt on.

Personally I couldn't wait and went for the bolt on's first.

I probably will not reach the limit where I do need to crack open the engine.. but who knows. Maybe one day.

Cheers and thanks for all your help guys. First thing on the list...Power FC. ooohohh can't wait!!!!!!!

Now I'm gonna go and put myself in a coma so when I wake up my skyline would have arrived. This wait is killing me :D

hmm rb26 heads on rb30 block...then when you feel like upgrading then bolt on the goodies

yeah i agree with Ryosuke Takahashi, if you want to build a tuff engine first than build an RB30DET, then start piling on the bolt ons :D

    • Old Son, did you re-use the Holden ABS in the new shell or try a different module?
    • Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.
    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
    • Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
