Hi guys,

Quick question... im after roughly 230awkw on my gts4.. will a stock rb25 turbo get me this ? i know about that ceramic shit but if the ceramic wheels replaced can i achieve good results without going and spending a couple of grand on a new turbo ?

just asking coz theres one for sale for 100 bux with a dodgy actuator on another thred.. might grab it if u guys give me good feedback ?

cheers guys!

would this be a direct bolt on to replace my rb20 one? also for the time being is this a beter turbo untill i get it high flowed and stuff? ill be puting my rb20 actuator as the one on it is apparently not holding boost so what do u guys recon for 100 bux should i grab it ?

If the turbo itself is good and its only an actuator thing then it is pretty cheap. Do a search for putting 25 turbo onto a 20 :D

Straight swap, you will just need the turbo elbow with the turbo. Everything else will bolt straight on. If the turbo is fine and its only the actuator than that is a good upgrade for $100 assuming you can swap the turbo yourself. To put it into perspective, i sold my stock turbo for $250.

Quote seller "A little in and out on the rear housing turbine, but no shaft play side to side "

so all i need is the turbo elbow and I'm set i really wana do the install myself as i really wanna learn about it all and want to give myself the experience not afraid to attempt it... am i going to need gaskets n shit ?

The turbo sounds to be in good condition if the seller is telling the truth, for $100 worth the risk.

Yes you will need a T3 exhaust gasket that goes between the manifold and the turbo. Your dump pipe gasket might be fine if it is a metal one, however replace it anyway since it is all apart and the gasket doesn't cost that much. You may need some washers, bolts or nuts if some need to be replaced. Good to hear that you want to do it yourself, it's the best way to learn and you will learn a lot from doing this. Just follow the instructions on some of the threads on SAU and if you have any questions while doing something ask some one to make sure you don't have to pull it all off again. There isn't much that can go wrong so go for it.

      Boost level and torque curve

      By Lithium · Posted

      There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done.

      I am impressed with all this level of adjustment. I didn't expect all this possibility

      Boost level and torque curve

      By Lithium · Posted

      Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.

      so you can decrease or increase the boost depending on the diet as you wish?     by acting on the wastegate?

      That's torque and power, it's all from a single run.  The boost curve is "held back" from it's peak target in the 3500rpm to 5000rpm range from memory, so it ramps hard to something like 18psi then climbs more progressively to 23psi nearer 5000rpm.   It makes the torque (and power) ramp more "natural" and less hard on parts and traction, it doesn't feel artificially held back.
