Yeah Jason we played with the profec on that - did a few half pulls to try and get it on harder, but it made stuff all difference. I settled on a setting that gave the flattest boost curve for ya.

I thought about cranking the boost up some more for you but it's hard to say when enough's enough. I could have spent all day on the car, but you have to weigh up what the gains will be versus how much the customer is prepared to pay, if ya know what I mean.

If ya want us to push it some more, just give us a call and book it in. Happy to help. Just remember though that it wont last forever when you start stressing things out!

Have you any experience with cars that have been under your care for a good period of time and know that all the support systems were there, no silly spanner work or temp/detonation issues occurred...subsequently got a good feel for how long they live on the street at say 320-350rwhp???

LOL i ask because i have been on a mission to see if my little RB20 will start to breath or struggle at a bunch of track days this year...so far so good...and i so want to wind another 2-3 psi into and get it up to 19/20psi and 250-255rwkws:)

Im waiting for a new turbo that will hopefully allow me to get those numbers with 16-17psi...will see how it all goes, car has to live thru Sandown in 2 weeks time:)

Cound'nt of said it better myself Glenn.The tune before was to hardcore I think as it had way to much knock!

You did a mint job and I'm loving it!!!

I'm thinking maybe going the stock exhaust manifold? as a crack looks to me starting in the china one.

I reckon it would be worth a go with the stocker back to back to see what difference it makes.

Roy, no one with an rb20 in WA is making anywhere near the power figures your talking about as far as I know.. Fair few on 300-320 but thats about it.

Thought id post in this thread as i've been reading it for some time now, And i jus finished a bit of work on my car,With results im fairly happy with 219rwkw @1bar.

Car feels very punchy and im sure it will keep me happy for atleast a couple of months.

Pointless thread i know, But it feels good to finally make over 200

Details of the setup PRO_32? Thats good power on 1bar:thumbsup:

As for WA, was kinda hoping that there may be a car in your Prod Car/Street car class running an RB20 in the series...lol piggyback some feedback from a few seasons of bashing around Barbagallo with a big turbo on it.;). (Cant recall the name of the series, thought it was street car but no sure)

Our involvement in the street car scene has been with an SR20. We run 430hp at the treads in all-day-race-trim.

nobody here runs an RB20 in that area.

All of the high HP rb20's I've done end up dying because they were 150,000k's old before the mods started, and as they generally end up in drift cars, they get absolutely belted stupid on the road.

I reckon it would be worth a go with the stocker back to back to see what difference it makes.

Yeah, and graft a big ext gate onto it...........

Roy,

what is this new turbo you are waiting for?

you can PM me if u don't want to mention it here.

Hey guys just bought my R32 from Japan.

Car mods as follows:

TD-06 turbo with external waste gate (50MM i believe)

bigger injectors (with extra injector for high boost)

GReddy injector equaliser control (is what i've been told it is)

aftermarket ECU

electronic boost controller

upgraded fuel pump and swirl pot

adjustable fuel regulator

GTR intercooler (replacing stock intercooler) want a FMIC

3' dump from the turbo into rear muffler which is standard at the moment, with extractors.

GTR rotors and calipers (is what i've been told)

irridium plugs and upgraded ignition coils

rods and pistons have been done as well as bearings (is what i was told)

set of race springs and HKS front and rear strut brace.

Apexi air intake with modded CAI /Heat shielding (thanks to SAU thread)

button racing clutch and locked diff (want to change diff)

Have not dyno'd the car yet as im still getting it on the road and everything sorted out. When i do i'll let you know how it goes.

Talking to the tuner yesterday and he said if didn't have a couple of hundred kilowats after driving it he said he would eat his hat :Pimp2:

Can not wait to get it on the road although u have been re thinking it as a daily driver now!!!

Yes with that turbo it wudnt be a daily driver!! Thats for sure lol

But will make alot of hp and once you learn to drive it be good for the drags itd think

Sounds sweet

well i will turn the boost back to 0.6 or 0.8 bar for daily driving and running around. and when i head to the track or go drifting i'll wind it back up again (as it takes about 5 seconds to change :Pimp2: )

had it at the track yesterday to see what it was like actually, no trouble driving the car, but i can see i will have trouble keeping tyres up to it if i keep the boost where its at the moment :innocent:

i have no doubt it will produce the goods, just have to get the time to service it, get it on the road then dyno run to see whats its doing, tune it and then its back on the dyno to see what it produces.

Will keep you all posted but i hope to post back up in the next couple of months with something over 200rwk's :matrix:

lol i was thinkin huge ass turbo = lots of lag??

And rb20s arent the best engines off boost!

There is minimal lag actually. It has a electronic set up for preset boost at rmp as well as the EBC. This unit also controls the fuel for the extra injector.

And as for RB20's not being good on boost or off i dont think you will find a better motor for rev range.

Different tuners so i have to overlay the plots myself:)    

People always say too small an A/R exhaust hosuing chokes up top end, well the 8cm makes more power everywhere...makes me think whether the 6cm housing will give it more midrange without impaciting on top end...i suspect 6cm may be too small:confused:

TD06_Plot.jpg

LOL..at 4,000rpm it makes exactly double the power and is on full boost:)

Hey Roy, just a few questions, u have a rb20 with a td06 20g right, and u made around 250rwkw,

what psi did u use, what other supporting mods do u have, did the tuners say the turbo had much more left in it rwhp wise.

    • You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?
    • Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
    • Could be correct. Meter might be that far out. Compare against a known 5 ohm 1% resistor.
    • @Murray_Calavera  If I were an expert I wouldn't be in here looking for assistance.  I am extremely computer literate, have above average understanding on how things should be working and how they should tie together.  If I need to go to a professional tuner so be it, but I'd much rather learn and do things myself even if it means looking for some guidance along the way and blowing up a few engines. @GTSBoy  I was hoping it would be as simple as a large vacuum leak somewhere but I'm unable to find anything, all lines seem to be well capped or going where they need to be, and when removed there is vacuum felt on the tube.  It would be odd for the Haltech built in MAP to be faulty, the GTT tune I imported had it enabled from the start, I incorrectly assumed it was reading a signal from the stock MAP, but that doesn't exist.  After running a vacuum hose to the ECU the signal doesn't change more than 0.2 in either direction.   I'll probably upload a video of my settings tomorrow, as it stands I'm able to daily drive, but getting stuttering when giving it gas from idle, so pulling away from lights is a slow process of revving it up and feathering the clutch until its moving, then it will accelerate fine.  It sounds like I need to get to the bottom of the manifold pressure issue, but the ignition timing section is most intimidating to me and will probably let a pro do that part.  Tomorrow I'll try a different vacuum line to T off of, with any luck I selected one that was already bypassed during the DBW swap.  (edit: I went out and did it right now, the line I had chosen did appear to have no vacuum on it, it used to go to the front of the intake, I've now completely blocked that one off at the bracket that holds several vacuum lines by the firewall.  I T'd into the vacuum line that goes from that bracket to the vacuum pump at the front of the car, but no change in the MAP readings).  Using the new vacuum line that has obvious vacuum on the hose, im still only getting readings between -6.0 and -5.2.  I'm wondering why the ECU was detecting -5.3 when nothing was connected to the MAP nipple and ECU MAP selected as the source. @feartherb26  I do have +T in the works but wanted to wait until Spring to start with that swap since this is my good winter AWD vehicle.  When removing the butterfly, did it leave a bunch of holes in the manifold that you needed to plug?  I thought about removing it but assumed it would be a mess.   I notice no difference when capping the vacuum line to it or letting it do its thing.  This whole thing has convinced me to just get a forward facing manifold when the time comes though.
    • Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
