Hey Ben, Congrats man thats very nice power !! RB20s still rock ! 12 years on

One suggestion though, turn boost up a little higher say 1.3 - 1.4 bar.

On mine from 1.2 to 1.4bar really starts pulling hard @ 1.4.

cant wait to put the Rb26 cams and pulleys. Gotta do the clutch first tho..

yeah i plan to get it on the dyno again next week before WSID on wed night, I might just do one power run on high boost, but i get a little scared, this is my everyday driver so i need it to run reliably :(

But like i have said before, i need to have a dyno print-out with over 300rwhp and my name on it. just so i can say i have over 300hp

what does everyone else think about running around 1.4 bar? on a stock RB20 with std headgasket? i was considering running the 1.2bar when i race, but for everyday i only run between 0.8 and 1.1bar.

MRK25T you need to let it open up, these turbos are designed to run highish boost to reach their efficiency peak @ 1.3 - 1.4 bar...  

theres a shitload of power to be had from 1.0 - 1.4 bar...

The next owner can boost it more, I couldnt afford a new engine if it blew so got it tuned acordingly. The tuner at Procar did a great job with the car, it is very smooth. Notice how straight he got the AFR.

They are a great turbo, much better than my high flowed standard turbo.

yeah the A/F ratio is awesome on yours! i need to get mine like that.

was it Paul who tuned your car? he was very helpful and knows his stuff, he showed me some stuff on a 900hp NA V8 he recently built! imagine having an NA 900hp engine!

I really need to invest in a PFC! anyone got one cheap for me? hehe

yours will pull some awesome numbers once the boost is in mark.

No, a specialist tuner came in to do my tuning at Procar.

WHo was the tuner mark? Dont be shy.

Paul from Procar will tell you. He doesnt do any joe shmoe off the street. He tunes the car only if you are sitting in the car with him the whole time and explains everything. I dont know cars, but I did a fair few units of physics in my science degree and it all made sense to me.

The car is no longer mine, sold it this afternoon.

      To be fair passengers who aren't silly and have been in proper fast cars have often been pretty impressed once you hit 4th gear

      I suppose that's true. Barring almost any situation, I'll never sell so what the market does is kind of irrelevant to me. It's possible I'd make most of my money back. That spreadsheet I mentioned? Maybe I could make back more than what the car's total costs thus far are, but the parts and all that is possibly a different story... Thanks for reading. It was certainly a good moment and just makes the ties to the car that much stronger. It's exciting that the option will be there to bring it over, however I have some plans with a shop that may end up keeping the car there longer, not sure. Coupled with the fact I want to move there and haven't solidified any path yet. So in a way, it feels like I'm in a limbo state that is uncertain; time will tell.

      No worries, everything worked out in the end. I just wanted to make the point that it doesn't matter where it comes from (I.E Australia), it can be broken or improperly built. I would still purchase from these companies in the future. B2R - Not certain how that finished, this was on a car I wired a few things and street tuned. I know the owner ended up shipping the motor back to Australia for investigation. Hopefully some of it is covered under warranty.  Turbosmart - I always pressure test everything that goes on my car. It's a habit from my career in oil and gas. I run two 40mm's and both had major leaks from the actuator to exhaust portion through the shaft. I returned both, they shipped me back two and one was leaking and the other had a 38mm top (40mm gate with 38mm actuator cap, no idea how that happens). Eventually after a lot of back and forth I found myself with two non-leaking gates. I believe this happens a lot more then people would like to believe but you would never know if you don't pressure test them prior to installation. Crank Motorsport - Issued a full refund and let me keep the seat rails. I turned them into scrap metal for other projects. GKTech - Shipped me out a replacement and asked that I modify it as per my idea and that they would do the same for a future revision. ATP - Can just needed a large shim to bolt up properly.  Haltech - They started an actual proper Beta channel for firmware's a few months back and stopped using the general public for testing. I'm now much happier.  Speedtek - f**k Speedtek. I would love to watch them burn.

      I've got a Turbosmart wastegate, ATP catch can, many GK Tech parts and Haltech everything. Everything's been perfect, sorry to hear your experience wasn't the same
