I'm about to boost my n/a 34. Intercooler etc is sorted and fab work.

Q1. Do rb25 turbos and rb20 turbos use the same oil lines ? Because I have a set of speedflow braided oil feed and return lines an I want to know if they will bolt straight into rb25 turbos.

Q2. How would an rb20/25 turbo go if I get it rebuilt with a billet wheel and high flowed with a kinugawa adj actuator ?

Q3. Cost vs cost, which is better ? ^ that or going straight out and buying a kinugawa TD06 20G ?

The plan is to only run around 10psi as the n/a motors have higher compression values then the 25det neos. To pair with this, I'm just going to run the factory low mount manifold with a 2.5" twin entry dump, greddy type FV BOV and drift boost tee.

What's my best option ? Cheers guys. Kinugawa TD06 or rebuilt rb20 or 25 turbo with billet wheel and kinugawa actuator ?

Not much. Picked up a GREDDY FV BOV, permaseal gaskets, factory turbo manifold, twin entry dump and boost tee for $180 and I already had speedflow braided oil feed and return lines.

Looking at $400 for a return flow cooler with piping, $1k for a nistune install and tune then I'm looking for an op6 turbo or something similar.

You running factory non-det injectors and fuel pump?

If you're buying injectors and a fuel pump I'd sugest going straight for E85. its perfect for the higher comp motor and you will make more power on that small turbo

    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.  
    • Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
    • There is a warning that "this thread is super old" but they ignore that anyway...
    • With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
