Sliding Performance Hiflow Picks And Installationon Rb20det

CEF11E,

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

[Cameron_Datto]

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

ive got a full 3 inch dump to tip exhaust, however jeff noticed that the wastegate wasnt flowing enough aand it creeps up in boost at high rpm.. either that or my bleed vlave is causing drama's

[CEF11E]

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.

[Simon-S14]

whats this turbotech controller you speak of?

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.

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.

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

Should be interesting how it spools on the 2.8ltr. Should be similar to how it would perform on an RB30.

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?

[Cubes]

Loaded up my old rb20det stock turbo at 1bar used to hit it a shade over 3000rpm.

General driving, second gear low speed out of a corner used to see 1bar by ~3500rpm.

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.

[Cubes]

The plugs u want are BCPR6E

v-groove and 0.8mm pregapped.

Not every one keeps them.. Coventrys/Motortraders do. They are around $2.80 each.

[CEF11E]

Thanks Cubes.

Are you going to get one of these turbos you haven't still got the stock RB20 turbo on your RB30 have you?

[Cubes]

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.

[CEF11E]

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

Are BKR6EIX's suitable for this application (slide turbo 18psi in rb25)?

[Tangles]

Glad you are happy Ceff11e - mate I cant wait until monday and the install for my Slide turbo.
