Hey... How are ya Macka... :P I sure do remember those threads :D

Adam they were the stock turbo's I was talking about.. :D

The RB20DET is a smaller motor hence it consumes less air hence less rotation speed for the same psi compared to a RB25DET. :)

I'm surprised the RB20DET Turbo has lasted this long actually. Its getting close if not already passed 1 year since i've been running it at 16psi.

Awesome result! That's the first 12 I've heard of on the stock turbo.

I also run around 1 Bar on my stock turbo and I've had no problems. I think most ppl are just a little conservative with their turbos. In my experience, the S1 turbo is good for 1 Bar, but ppl just like to repeat what they've heard about them failing at this level. They may not last as long as one at stock boost, but that's just a fact of life when you turn up the boost. I've given mine many a spirited run and no blades have come off (yet :D hehe).

That said, there's no way I'd run this boost on the racetrack. Guaranteed turbo failure.

S1 stock Turbo's are only around the $500 mark anyhow I believe, not going to be a -huge- repair bill if something does go wrong.

When I was trying to get a good VG30BB from JMS I asked them how much a S1 R33 Turbo was and they told me $800-$900. :D

Great time! Have you had the turbo off the car?

Mine came off and had a modified front wheel, and the ceramic rear wheel was changed. You might have gotten lucky too!

Excellent times none-the-less!

Not the 16.3 one either.. :)

Yeah 111+mph is better than a few upgraded turbo GTS25t's!

My turbo has the potential to get me a bit quicker over the 1/4. 115.83mph on a 13.60 with 2.667 60ft shows this. The larger the turbo & the harder it comes on boost the trickier it becomes to launch successfully, unless you have very very good traction :)

The nice progressive power delivery of the stockie makes it much easier to launch, or more to the point even with a so-so launch the car will still be quick over the 1/4. Take our 60ft's in my 13.0 @ 113 & Matt's (BOOSTD) 12.9 @ 111 - I actually have a quicker 60! (2.238 vs 2.247) But where Matt's turbo would recover quickly from the bogged launch mine would be still spooling up.

The Microtech can probably do the same task? But as I like my old HKS EVC I've never bothered to look into it. Lazy bugger ain't I :)

Ahh I like the challenge of doing it the hard way :)

I have had the turbo off, because no one believed it was stock when it produced 218rwkw, and yes it is dead stock... go figure. It does have a fuel filter the size of a Milo tin and a bocsh motorsport pump(installed after last dyno) and I must say the high flowing fuel system did give it a noticable increased shove into the back of the seat.

Power FC indicates injector duty at 99.8% and my Stock A/F meter runs out of resolution @ 5000rpm. As you can see there is nothing left in it. Thinking about a Z32 A/F meter and adjustable fuel regulator- has to be more tuning to be had up above 5000rpm.

What power were u making before you did the fuel system?

Im on 203rwkw with the stock ecu and stock turbo but have a malpassi fuel regulator sitting ready to be installed/tuned. Hoping this will give me those extra few rwkw that I want.

I haven't dynoed it since I installed the pump, but, it did half my detonation levels. Must have been running alittle lean.:confused:

Hello all just like to get a few things right.

the TD-06 I used was from a VG30ET, yes pretty old school but worked very well, it uses an actuator and bolted onto the standard Manifold, starts making boost from 3,000 and really starts to kick in at 4,000. It is not a 600+ hp Turbo either, td-06 19C. It made 302kw's @ the wheels at Tilbrooks Dyno Center running 1.2bar boost. We couldnt go more as the standard manifold was restricting things. The $1,800 for the Turbo was a bargain , 11.3 @ 122mph is testiment to that.

tOOK bOOSTD for a drive in it today, I'm sure he will confirm what I said.

    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

    • Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
