Sorry if I missed it, but why stage II instead of III? Does John not make the III anymore? Isn't III higher than II, making that the "mother of all turbo kits"?

ehall

well the Stage 2 should spool up faster on a 2.5ltr, with head work. It should really hit hard, and pretty early. The Stage 3 will have more up top, and spool slightly later. It's really a matter of where you want to perform the best.

That said, I'm not speaking for either of the John's.

porshhhh951

exactly correct.

The stage 3 is a great unit but, alot more up top sacrifcing a little on the low end. I want a street turbo that has similar spoolup charactristics comparable to the 26/6 but, that can deliver alot more up top.

Its my understanding the stage 2 is good for around 400 at the wheels which is about the most i'd ever want outta it. I'm not looking to be the next special tool. The car will see 18psi and pump gas 90% of the time.

well see what it makes for power but, im more or I should say equally concerned with power deliver and how early it kicks in. After talking with john this was decided to be the best course of action for my car and my plans.

Well I would think that even VR would be surprised if the StageII reached 400whp at 18psi on pump, but I can attest that having been in JET951's 2.5L with the SIII kit, you really are not penalised by lag and it holds boost to redline so I wouldn't be worried about that turbo on a 2.5L IMHO

porshhhh951

400 wont be possible on pump gas.

i'm hoping for 350ish on pump.

nize

i'm actually going for 400+ on pump.

porshhhh951

yeah it'll be interesting to see your numbers.

my stage 2 is a smaller unit than what I could have gone with but, my motor is stock displacement and its a street car anyhow. I'm not so concerned with top end power as I am driveablity and powerband. However I think we got the size right I should be able to make decent power on the big end too.

time will tell I suppose. Regardless its just a stock 2.5 with a head/cam. Nothing special about it.

Not quibbling. It will be just fine you bet.

We took my car to 18psi today. 345hp. It's getting better the higher I go. Its really proving that 440hp is the sweet spot. I'm out of injector at this power though!? 1600's going in on Friday. Do I get an award for the largest injector? Anyone?...... no? yeah. I didn't think so.

With your head work and cam. I can't see how you wouldn't get at least 360. at least.

porshhhh951

what injectors are you running right now?

95ONE

1000's.

I just did RC engineering injector calculator... It's dead on.
It says I would run out of injector at 340 whp at 55psi. with 1000cc using a bsfc of .86 (E-85)
- 80% duty cycle -

It also says if I want to go to 500 crank hp. (They all use a 14% loss) = 430whp
I will need 1300's

Soooo 1600's it is.

bigdeano

So much for that 4 cylinder fuel efficiency haha.

porshhhh951

are you running stock fuel pump?? and at what fuel pressure are you using.

am I going to run outta injector/fuel

im running a 044 fuel pump,83lb injectors, 3.0bar fuel pressure.

95ONE

If you're running gasoline - you're fine. Plenty of fuel.

Just did the RC worksheet.
80lb injectors for what you need. - 3bar fuel pressure. 80% duty cycle. 400crank hp.
