Would be interesting to see how much KW you pick up with a larger exhaust dump pipe from the turbo ,

any one know if they run the larger VG30 ex housing on the rb25engine for the Siding turbo up grade ?

Looks good should be happy with $$ you spent on the turbo

My boost was holding perfectly at 16psi with the turbotech controller. I amso have a 3" split dump from the turbo back to the cat.

Cubes, Live edit can be used as a good ground for a base tune but is not accurate down to 1/2 of an afr by any means, especially when you start changing the injector size.

but it is a good starting point.

CEF11E,

Live-edit... How well does the afr display reflect real world afr's?

In most cases not even remotely close for the open loop stuff.

The closed loop stuff should be fairly close assuming the inj and maf are calibrated correctly.

Well I have placed an order with Slide, on a recent trip to the sunny Gold Coast I left a VG30 turbo with him to be MAX FLOWED.

When it comes back it's going on my new L28ET engine, which will be interesting, or hoping so.

Will let you know what it looks like, as he says it will be back by about 26th November.

Cheers, D

Got my Sliding Performance highflow for a AWD RB25det Stagea, received just now

Looks wild !!! Been bored-out to the max! Getting installed on Monday, dont know when the safc & sitc will be re-dyno tuned tho. So I'll keep it under 10psi until its tuned.

Hopefully get the exhaust cam gear wheel installed at same time. And my brake upgrade, time permitting.

this is going to sound like a dumb question (and it may have been answered in the middle few pages. i read the first 2 then skipped the rest), but what does it hit full boost by on the rb20, and what does the stock rb20 turbo hit full boost by?

turbotech boost controller = designed/sold by a guy on these forums for about $35... also retailed by DrDrift

works a bit differently (Better) than a bleed valve... brings boost on faster etc.

sounds great, i want one.. who do i contact to purchase?

cheers

simon

look for one of my old threads called I found a good cheap boost controller for $22.

it is in the forcen induction section and there are about 100 pages of info on it :) the guys name is Mark and his email address is on the first few pages.

Cheers :)

I am working thru my spark issue and turns out I was wrong about the plugs I was using. I had a set of NGK BPR5EIX-11 plugs!!! supprised it didnt miss at 10 psi!

I have just bought the wrong plugs by accident... BCPR6EY-11 Do'H!

The plug height is shorter than the BCPR6ES. they are in the car untill the weekwnd when I will get the bloody correct plugs this time gapped to 0.8.

lol No the rb20det turbo is off it has been running a vg30det turbo for some time. :)

The VG30 is better but still lacks.

These turbo's are cheap, but I really want to throw on an int. gate gt30 .82. and ram as much boost as I can (20 odd) in to it.

A gt35r would be nice but is a tad too laggy on the 3ltrs especially when they need a plenum to make them rev hard. (as we recently found out on a mates car)

BUT... I really am getting tired of driving a car that has a decent motor but crap turbo on it so it very well may see a vg30 max oversize slide turbo thrown on the side. See how things go. :)

I am currently having issues with coils but have had some more time to test.

I have leaned out the tune to 12:1 and put in new plugs and gapped them to 0.8 and am now running 18psi. after 1/2 hour the one of the coils starts to produce missfire so new coils are on the way but the car REALLY moves.

I would estimate there is at least an extra 20rwkw increase taking it to around 230~235RWKW and boost feels like it is coming on much quicker. it starts to get up and go at around 3600rpm.

this is still with the 2.75" exhaust. I really have to say this is a great turbo. I don't care if it is bush bearing, it is a better match to the RB20 than a lot of turbos that cost twice as much. I am really happy with the performance and have pushed the little RB20 as far as I think is realistic for a daily driveable car.

I couldn't be happier.

Cheers :(

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
