I have just brought a gen3 3584rs with a 1.15A/R 5 bolt rear and t51r mod front, 10spi actuator. (Only running internal gate on low boost, im running a 60mm progate at the moment) and ANTZ 1250cc bosch injectors ( won't be installing till its at the dyno, I have nothing to scale them) I still have head studs and oil pump gears to do and kelford 218b cams which I think im not going to use, but besides those things what sort power would I expect ? It's a healthy overly maintained stock FG F6 engine Link to comment Share on other sites More sharing options...

But in saying that it brings on boost around 2k maybe a little lower and full boost (12psi) around 2.5-2.7k. I haven't given it a hard time yet. Im hoping to have everything done and tuned soon. My priorty now is going through NZ LVVTA at the to get everything done for a modification certificate. so I am trying to do as many things possible so theyre on the cert dongle so when the/or if the cops pull me over they can scan it and all the modifications that the cars been certified for come up. Talked with the guy who's doing the dyno tune. I said I'd like a reasonably safe tune till I have built the other bottom end. Then we can push it he said we'll probably aim for around the 450rwkw mark give or take since it's a stock fg f6 bottom end still seems a little high to me but I'm not going to beat the hell out of all the time Link to comment Share on other sites More sharing options...

They almost all improve mid to top end, and normally shift boost threshold higher. Also, with a stock motor, most tuners are pretty hesitant bringing in boost too early Link to comment Share on other sites More sharing options...

It's fine though cos it's better for the engine, better for grip on the road and better fuel economy cos it will be using less boost for gentle driving. Plus you can always get hectic and send it to 600+kw if you are game to do that on a sbe lol Link to comment Share on other sites More sharing options...

And bring on boost better. Not keen on pushing that much I'm going to be happy under 450 I think it's plenty for now Link to comment Share on other sites More sharing options...

You'll see more variation than that from hot to cold weather. Link to comment Share on other sites More sharing options...

Tom Tucker Donating Members 669 Member For: 5y 6m Posted 26/06/24 09:56 PM Share Posted 26/06/24 09:56 PM Cams are worth it depending on goals. But they make tuning a lot harder, which is why you've had that experience with a tuner. Cam specs and timing introduce variables that require heaps more time to make the car drive nice.

I did a research and found why he was interested in tuning with cams.. haltech - live tuning. pcmtech - run the car up, turn it off, make adjustments, flash the pcm, run again. And repeat ... seems like pcmtec will add a ton of time during a tuning process then throwing cams into mix.. probably going to end up not using the cams to be honest. I'm a solo dad and I have spent way to much already and I originally was only getting it ready for a mod cert for suspension and wheels and it grew from there. The turbo I had to do the flapper was removed and welded shut the 3584rs gen3 at my cost through work with the t51r mod was only a couple hundred more that get a stock one Link to comment Share on other sites More sharing options...
