Well I finally got around to getting a PFC so I could make the most of my setup. The turbo was sourced for $600 from Rigoli in Sydney when I killed one. I was told it was modified a bit. Suggestions are that a HKS 2350 (correct me if wrong, I am no turbo fetishist) will supply this kind of performance so for the price I am real happy. Since the turbine spec is unknown I will remain limited to 15psi max.

The build consisted of:

Arias Forged Pistons 1.0 mm OS (1300)

GTR rods with fresh bolts (400)

ACL heat treated race bearings (120)

Balance, clean and O ring block etc. including straighten of crank and lightening. (1100)

GTR fuel pump (180)

Malpassi Rising Rate fuel reg (120)

Standard head gasket (90)

Cam belt (90)

RB30 seals (60)

JustJap 5 puck sprung brass clutch (550)

Hybrid Monster FMIC (700) piping (120) new Mig welder (700)

Autohouse Tsukasaki PFC (secret)

Dump and front combo 3" with Fujitsubo "Jasma" 3" stainless system and racing cat also fitted.

Total of the critical bits was 4200 (4800 with turbo) . My labour was 25 hours.

It was running OK sometimes on the stock 'puter but I had to fiddle timing and TPS and idle so not optimal and I couldn't gurantee the performance without doing some changes that left it idling at almost 2000rpm.

I went to see Rob at Creatd near Broadmeadows for the tune, which was a co-effort (mostly Rob but good to see 2 pros working together) with Danny of Brusciani Racing as they have the dyno as part of a working arrangement for fabrication. Brusciani have probably the fastest street registered VL turbo in the country with a high 8 and they intend to hit the Calder strip tomorrow night (9 Jul 04).

The result of the tune was an awesomely driveable (4th gear dyno chart) 220rwkw non shootout mode with peak boost of 15psi, so there is margin for dyno-queen numbers on shootout :). Tunes like this can be had for a few hours effort and about $250-300 depending on the starting point. I also had the redline lifted to almost 8000rpm as the engine was built to take it. Power drops over 7000 but it is for the track where I can avoid gearchanges and just rev a bit higher between corners.

While there is nothing quite like doing it yourself, tuning is one for the experts and this dyno run was repeated time after time with the great AFR's displayed. I can absolutely recommend Creatd for their tuning and was impressed by the range of cars in the shop and the clever ideas that Rob can apply to your machine.

If the turbo eventually goes I will chase a bit more power with a brand name blower but will also do the injectors. Still have some handling to sort out. The quest continues.

The other change I am looking at is a set of GTR turbos and perhaps plenum and throttlebodies. I spent a bit of time yesterday measuring up and comparing and it won't be too hard at all.

Good pickup as always Enrico, thanks. Most of the runs were fourth and a couple in second and third. I do know this run wasn't taken to 8000rpm as the power drop was too great to try to improve. It's only there for track flexibility. A better turbo will make greater use of the higher limit I expect.

The good news is I don't have a hand controller so won't be tempted to fiddle :D

Pardon my cynicism but I expect that most turbo places would have no idea if they are honest, try to tell me it's crap to buy a better one if they are not honest and still expect me to pay for the privelege either way. I like the element of uncertainty and if she dies, I've got 3 other cars to drive until the twin turbo setup is installed. And why do that (TT) you ask? Because I want to.....just for fun.

Can't bag it till ya try it.

Why not :mad:

A few will flame me for this, but drags is all about hooking up off the line, time a car between 100km/h ->200km/h (or 60km/h ->200km/h) thats the measure of performance that impresses me. :)

Wait a week or 10 and my car may be ready, ill race ya for pink slips :flamed:

yumm-i .. looks very track capable and i am sure that is exactly what you built it for :mad:

great to see the prices laid out there for others to go by in future just as a general guide to know what they are in for :) 8000 redline huh? should scare a few sr20's with that one.

The 25hrs labour was obviously ontop of those prices?

The good news is I don't have a hand controller so won't be tempted to fiddle

:werd:

i think the 25hr labour was his own.

also in regard to 3rd vs 4th gear dynos, power is exaclty the same, as confirmed by the dyno on my bedroom floor.

Looks like a tru track warrior, good mid range, and phat curve, plenty of power...... for now :)

Geoff, do u have an exhaust side adj. cam gear. COuld be a great investment if u dont :mad:

Excuse my ignorance but are the AFR's abit sorta howya goin ? ?

Roy: Your thing is farken quick.... from 5,000rpm onwards :( Would take me quite some time to get used to that sorta power. I'd need someone to tell me what to do coz i'd be too busy hanging onto the steering wheel :)

Benm, tell me what u think is wrong with them.

Too me they look excellent, nice and safe, which is what geoff would need being he is intending to use the car on the track alot. a perfectly tuned car, if there is such a thing is not goin to have a flat afr curve, it just doesnt work like that.

so, id say no the afrs arent a bit how ya goin :(

Don't really know coz i'm still learning that side of things.

I was just of the impression that a nice flat afr would represent a quality tune (amongst many other aspects of tuning of course). I've seen some dyno charts that are near perfectly horizontal and others that jump up n down like mountain ranges.

Live and learn I guess. . .

Benm, i know whay you are saying and i think the dyno run may have been done with the car cruising at part throttle at approx 50km/h (closed loop 14.7:1 A/F) the floored it causing the ECU to go open loop where it seems to run mid - high 11.5:1 A/Fs which is where most seem to be tuned to.

Some other runs may be driven up to 50km/h , off the throttle, then gassed/floored causing the ECO to run open loop straight away. That MAY be an explanation.

    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
