looks the goods lee

mid range looks good!

afr's are perfect, wouldn't expect any less from Martin.

Feels strong from 3500 onwards exactly what i was hoping for. Martin done a top job.

[Ryanrb25]

Sounds very simular to my last setup lee....good fun setup

Now, my boost starts building around 3500 and feels strong at 4200 lol...

[Martin Donnon]

This truly is an exceptional setup, and something I would do to my own GTS-t if I had one

251rwkw on our Mainline would be somewhere close to 280-290rwkw on the old one it replaced

All this with a stock airbox (only K&N filter panel) and a truly stealthy install. Very, very nice, and should be well capable of an 11 second pass when AIR reopens

when AIR reopens

inside information?

Cheers Martin i was purposely heading down the stealth install route the way us enthusiasts are hunted down these days by the boys in blue. Open the bonnet and nothing looks too out of place to the untrained eye. Definately very happy with the way everything has turned out thats for sure (back pocket a bit lighter for it but).

I would be happy to crack a high 12 some day to me thats a quick street car. Cheers for all your help in getting it to the way it is now.

[whatsisname]

haha, just razzing ya.........looks like a very good effort.......and welds don't have to be pretty, just have good penetration (well that's what my Dad says, he's a boilermaker)

Ahh, so many great potential one-liners in this thread, I'm spoilt for choice!

Nothing wrong with some good penetration... boom-tish!

And Joel, ignore Pete, I think your Mum doesn't a fine job with a welder

Now, back to being serious for a moment.

In my humble opinion, when chasing power levels at or above the 300rwkw mark using the RB25DET, it pays to bypass the internal wastegate options and go straight for a correctly sized external gate and piping to suit. In the long run you are more likely to get the result you're after with less hassle, and in some cases you'll actually save money that would have been spent stuffing around trying to fix boost control/creep issues.

I learnt the above the hard way.

So, would anyone like to buy my internal gate Turbonetics 0.63 T3 Stage 5 housing with enlarged internal gate outlet? It's good for 350rwkw on an RB25DET... and does a reasonable job of controlling boost

Ryan, it sounds like your Garrett (I'm assuming Garrett - can't recall exactly) 0.63 has the same response as my 0.63 Turbonetics - they're much the same design, so it's not unusual I guess.

Lee, nice result, mate. Got to be happy with that power and response. Upgrade the cams, add some more boost and there's a little bit left in that combo' still to come - up to 280rwkw on the same dyno.

[Ryanrb25]

yea it's a garrett..

Im heading towards selling the turbo and getting a GT3082r.

so much less headfuuk and will be able to keep my setup as is, eg Dump, manifold etc...all the while keeping it as stealth as possible.

[whatsisname]

If I had a dollar for every time I've heard of someone having to redo part or all of a new turbo set-up, I'd have at least $2 so far... in this thread. You and I, Ryan

We tend to start out thinking we can save a few dollars by not upgrading a certain part (i.e external gate in this case) only to end up with an overall result that falls short of our expectations. We then go on to spend more money, trying to get a better result, only to end up forking out for the part that we skipped in the first place.

You've got to laugh though, because we all do it at some point or another.

[Ryanrb25]

yea meh, as long as i get what i want at the end of the day, doesn't phase me. lol

Whatsisname, you think a gt30 front wheel and cover with the .63 would kind of eliminate enough flow to keep boost levels at a sensible level?

[whatsisname]

That's the spirit And much the same way I feel having learnt the hard way too.

I think a GT30 compressor combo' coupled with 0.63 external gate rear would be just fine. It will be responsive, will still make solid top end power, and with the external gate will hold boost without any creep issues. I wouldn't expect big 300+ numbers though - the GT3082 would be the choice for that if the latter is your ultimate goal.

[Ryanrb25]

so many options...hehe thanks for the info..will keep you posted.

[Cubes]

Ryan..

The GT3076r with the .63 IW rears still boost creep.

I would expect the GT3082 to be worse as the comp wheel is larger and pushes more air per revolution; in turn more exhaust gas has to bypass the turbine wheel.

But why the GT3082? You really can't make use of the comp wheel unless your start playing with better fuel and at the very least a .82 preferably 1.06 turbine housing.

The .82 rears appear not to experience creep issues. In my case and also another mate (Lithium here on SAU) who I helped out to get his .82 IW together, both of ours are fine - no creep.

The .82 IW GT3076 on the rb25 comes on strong around 4000rpm.

Dangerman4 who runs an the GT35r .82 IW has zero issues with boost creep but in the past similar boost drop issue I am having. He remedied his boost issues by fitting a stiffer actuator.

His 1bar actuator was fairly useless, then jumped to 18psi which allowed up to 24psi now soon he's fitting 24-25psi actuator for god know what boost levels lol.

Lee, nice result, mate. Got to be happy with that power and response. Upgrade the cams, add some more boost and there's a little bit left in that combo' still to come - up to 280rwkw on the same dyno.

Thanks Whatsis i'm happy thats for sure. Cams will definately be on the cards down the track more so for mid range than anything else. Nearly all the parts were bought off this forum and definately all the research has been from SAU so i guess i have all you blokes to thank . I originally was going to go with a 2835 but future plans are a forged RB30 bottom end (when the 25 starts to get tired or throws a leg out of bed which ever comes first) so the 3037 should be good for 300rwkw give or take.

[dangerman4]

my gt3582r-iw dump design,

on a highmount ETM manifold.

lives on 24psi / 320rwkws daily with no boost issues

[SLED]

far out, with all these nice looking dumps around, I'm contemplating making a decent pair of bellmouths for myself

[Ryanrb25]

Please tell me the motor is built lol

I've decided to Mod my manifold to house an external gate, keeping the .63 rear with the gt35r from cover and wheel...I really like the power delivery with this one. I can flat foot it off the line in first and it accelerated enough just before it breaks traction and that's what i wanted.

Thanks for your info whatsisname, Ill keep you posted on how it all goes

I'm looking to run 11's aswell in my ER34... I may have missed it but, is the 3037s being installed low mount?

I was looking to run either GT-rs or 2835, will i get approx. same/enough power to run into 11's?

Thanks

3037 S uses standard exhaust manifold with custom HKS dump as will the 2835.
