Nice! How is spool? <br /><br />Sent from my GT-I9505 using Tapatalk<br /><br />

haven't picked it up yet, ill grab it tomorrow , he just checking over cold start in morning.

[Dale FZ1]

So an improvement of 30hp in the top end but a bit of mid range loss?

Can you get an overlay of the torque curves posted up please.

[methz]

sorry dale I don't like to post dyno graphs, as my tuner ramps the car up different to avoid horrible wheel spin and the graph seems laggy if that makes any sense 2 you? so dnt want to start a shit fight.

but on the road it comes on a lot sooner then what the graph shows.

and old tune was actually 442 at 22psi. now 485 at 22 lost around 30hp in mid at 4500rpm but obviousily gained 40hp up top. pickup car this morning so see how it drives soon.

peak power went from 6600rpm to 7200rpm

hey i've had a search of this thread and googled but didn't find what I'm after, most of it seemed to be about the rb20.

I have an r33, daily driver auto on stock ecu and stock engine, and it's staying that way, although an safc neo ready to touch up the tune a little once the turbo side sorted. Usual 3in exhaust, hiflow cat, fmic, metal intake mods. I've been looking at the TD05 18g with 10cm housing and antisurge cover here

http://www.ebay.com.au/itm/Kinugawa-Turbocharger-Bolt-On-3-Anti-Surge-RB20DET-RB25DET-TD06H-25G-T3-10cm-/281245773483?pt=AU_Car_Parts_Accessories&hash=item417b8deeab

what are people's thoughts on this on the rb25 and running around 13-14 psi? Like I say not looking to change engine or ecu or run any high boost so don't need anything that will flow more than what I need, really after response (esp being an auto) and a turbo the 'right' size rather than room to make more power I'll never end up using.

I notice it's also about $70 cheaper from the kinugawa website rather than ebay, is that a marketing thing, or any catch there?

also the bullet-nuts they sell, while prob not a big difference it does look like it would be better aerodynamically (and they look sweeeet)....people's thoughts on those, and use aluminium or steel?

I really don't know too much about these so very keen on people's opinions and experiences. Thanks!

[Lithium]

If you aren't changing the ECU then don't change the turbo - it'd be folly to put an 18G onto an RB25 and try and run 13-14psi without tuning.

[hardsteppa]

Oh that's interesting, are you meaning that it will be flowing alot more than stock at that psi, or its too low for the td05's efficiency range and would need to run higher boost?

[Dale FZ1]

More the fact that the airflow characteristics - mass throughput - will likely be very different to what the OEM turbo does. So fuelling and ignition changes are needed to suit.

The age old problem with the OEM ecu of hitting rich/retard will also raise its head. Simply adding a FMIC, free flowing pod inlet, and 3 inch exhaust can be enough to give problems in that area.

Nistune could be your answer.

TD05 18G could be a reasonably good match but the HG options seem to have been proven a very good match. No reason to ignore the Kando unit though.

Thanks Dale. I do have the safc neo but of course more just for tweaking rather than redoing the tune. So plenty of ppl seem to run hiflows ok on stock ecu, guess the td05 is a different story tho. Pity, cause these are such a great price! And so much good feedback on their product.

[methz]

I ran a highflow on stock ecu on 17psi, motor lasted a few weeks....

[Dale FZ1]

I'd think of it as very much in the league of a lower end high flow unit. And yes the price is a draw card.

If you can modify fuelling and ignition with the SAFC then that should do the job nicely.

[hardsteppa]

Thank you. What are your thoughts on the antisurge housing for it?

[Lithium]

If you can modify fuelling and ignition with the SAFC then that should do the job nicely.

You can't - S-AFC just modifies the load signal from the AFM.

In other news, local drags next weekend finally - looking forward to seeing how my mates S14 Silvia goes with the antisurge 16G setup, getting some ETs and trap speeds should clear up any dyno difference doubts. It will be running 19psi on E85.

[methz]

what kinda mph are you hoping for?

im also hitting the strip on sat night at willowbank, hopefully can get atleast 125mph

[Lithium]

Awesome, good luck. I'll be lying if I said I wouldn't be disappointed if it went under 115mph, but it's really hard to say beyond there - it's got a really difficult to "read" seat of pants feel, its surprisingly quick though. I'd kindof like to see around 120mph, but realistically anywhere between 115-120 would be well respectable for such a basic setup I reckon.

All the SAFC does is intercept the AFM signal and move it up or down, with this your fuelling may change but so will your ignition timing as the ECU will think you are under less or more load dependant on tune. Funnily enough though i have a Super Ignition timing converter for sale that could work very well for you

[hardsteppa]

Lol thanks for offer...and sales pitch... But i'm ok. Yep i know about the safc/timing, or more impotantly, so does my tuner.

Anyway lets get back to the antisurge thing, ppl use and recommend?

LOL I guess we can talk about ECU's after the worst happens, if you prefer.

The general consensus on anti-surge is that you don't need or want it. Factual evidence to its pro's and con's are not readily available, but I believe the aforementioned is the opinion of most.

Be it myself I would be confident that a TD05H 18G 10cm would not necessitate an antisurge housing on an RB25. However, it should be noted that while an 18G flows a few pound less than a 20G, an EVO 3 spec 16G6 flows only 1lb/min (10hp rule of thumb) than a 20G, and is a perfect match for the TD05H turbine.

SO, again, be it myself I would be opting for the below unit in a 10cm (RB25, use 8 for 20) as the replacement to a highflow:

Wanting to get some advice on internal or external gates if someone could spare a few minutes.

Have just had my RB20 tuned with the following:

Stock RB20 internals

Z32 AFM

Bosch 630cc Injectors

Walbro Fuel Pump

PowerFC

GTR V-Spec II Coil Packs

Standard exhaust manifold

Chinese front facing plenum, standard runners

Generic looking FMIC

3" exhaust, pod filter

Kunigawa TD05-18G Anti Surge, internally gated.

15psi spring (I think)

Turbo Smart bleed valve

here is the Dyno graph, all looks reasonably normal

The problem I have is that it shoots to 15psi pretty quickly, then it sort of sits there for a bit until around 6 - 6500rpm then goes to 19psi. It just seems like the IG isn't really doing its' job, is it going to be worth spending the $500 or so it will cost to go external gate?

[scotty nm35]

The external gate does more than just control the boost though, it also flows better in the top end improving power/torque output. It's a great mod if done correctly, and perhaps hidden for defect reasons.

If you just want to control the boost a little better, you will need to die grind the existing wastegate for better flow, or get Hypergear to weld on an enlarged puck and machine it out.
