How did the power go with the richer afr's? Didn't drop too much?

Na i got some cam gears aswell and shaun managed to keep the power pretty much the same.

Awesome turbo those td06-20g's. On the std exhaust manifold or a nice highmount (Troy style)?

I'm to poor for the highmount, so standard manifold for me. Also keeps the cops away.

also sorry how much r the td06-20g???

Got it for 1200

Here's my dyno sheet. Got a bit heat soaked after a fair few consecutive runs and dropped 5rwkw.

Dynosmall-1.jpgTurbo Tune's dyno is very new and apparently very accurate.

Calculated when I get full boost again, I get it by 3000rpm :ninja: So 200rpm earlier than what I said before! (edited that)

(calculated using gear ratios, not what the gay tacho says)

Everything will line up on the RB25 turbo to R32s except for the quite early models which have different size banjo bolts for the water lines (7/8" instead of 15/16" for the RB25 turbo)

They are in completely different leagues. The TD06-20G is rated at 450ps (I think) where as the HKS GT2530 is only rated to 320ps.

2530 is only capable of around 220rwkw, where as TD06-20G can pull over 260rwkw

My HKS 2530 is making 230rwkw and that is through an auto box, with only an SAFCII (so Power FC = no timing or other adjustments).

Yes, as Evil34 said my R34 Neo turbo is for sale $450. Perfect condition, no shaft play, will bolt-on.

I disagree with Joel's statement - the R34 Neo turbo is basically lag-free! Even though the 2530 is rated to be extremely lag friendly, the Neo turbo definitely spools up earlier!

I also have an all-in-one front/dump pipe to suit for that bit of extra grunt $200.

For an afternoons work in the garage a very nice upgrade that will see you around 180rwkw without any tuning and stock boost. Mine was 177rwkw before I pulled it off at stock boost.

yeah she goes pretty hard - the auto loves it too! Took Munro for a drive in the other day and he was pretty impressed :)

Oh yeah, if anyone is interested in Skyline bits I am selling my turbo and lots and lots and lots of other (mostly R33) bits here (click)

I disagree with Joel's statement - the R34 Neo turbo is basically lag-free! Even though the 2530 is rated to be extremely lag friendly, the Neo turbo definitely spools up earlier!

Andrew you missunderstood my statement. :)

The R34 GTT turbo DOES lag more than the R33 S2 turbo. No if's no buts.

The reason Nissan was able to step up the turbine housing on the Neo motor without having increased lag issues was due to the head running better cams that pick up low end torque, improved VCT operation and improved ecu mapping.

The R34 GTT turbo is a great turbo don't get me wrong. BUT for the RB20DET the R33 S2 turbo is THE best turbo out of the nissan RB turbo line up.

Saying that the R34 GTT turbo may make ever so slightly more peak power than the R33 S2 turbo. BUT as I mentioned earlier, on the RB20DET average power is what accelerates the car quicker to its peak power. :D

ah yeah mate my bad, you are correct. Also the nylon impeller is what counteracts some of the extra lag from the larger housing. The Neo turbo would be fine on an RB25DET in an R33 though. More top end power too.

finnally installed an RB25 turbo to my RB20 after seeing it reccomended alot. definately feels laggier, but i rekon alot of that will go by putting a decent exhuast back on (went from 3.5 staright through, to stock). up high the difference is massive, boost is smooth and really strong once u get the RPM a bit, alot stronger than the rb20 turbo up high.

So what ya'll saying is that the vg30 turbo is too laggy on the rb20det motor

what turbo are you talking about

The jurnal bearing t3 style vg30det turbo?

or

The ball bearing t3 style vg30det turbo?

cause i have heard about some good setups with the vg30det ball-bearing turbo

I have had a stock silver -top RB20 turbo, a VG30 ball bearing and an RB25 Neo turbo on my RB20DET. I distinclty remember loving the VG30 when I put it on because it gave a fair bit extra kick; but it comes on far too late. I drove around for many years with this.

About a year ago I went to th RB25 Neo which is a massive improvement over the VG30, the car feels just as fast but with much less lag; having said that I would prefer less lag from the RB25 Neo to the point where I would go to the Series 2 R33 RB25 turbo next time just on peoples' say so.

^^^ The R34 Neo turbo is by far the most responsive turbo of any Nissan oem turbo, as it has a lightweight nylon impeller.

If you were going to change to a Series 2 R33 turbo expecting less lag, you would be very sorely disappointed.

Holy thread revival Batman

My current RB20 with a VG30 turbo feels a fuckton nicer on the street than my old RB20 with R33 series 2 turbo, so much torquier. Being 2 different engines it could be any number of things but all I know is my current car pulls way harder in low rpm than the old one, with a supposedly laggier turbo :(

    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
