Rpm is a roller speed ratio that i have to input rpm It matches the log from the Nistune. When i get back to the shop i will take a pic with roadspeed

Why do u ask?

I just prefer road speed. Some prefer rpm but i look at road speed as i takes into account diff and tyres so better real world result in my eyes

And those saying go 10cm on a 2L i think you may make a peak number easier, it may even be a few kws higher; but the net result is terrible vs an 8cm on a 2l. Sure the RB20 is different to an SR20 but the result will be the same....no mid range and about the.same top end. If you are worried about.combustion effeciency and back pressure but in a slightly bigger.turbine or better flowing turbine in the same housing size. Seems that will give a better ovrrall result then putting too big a housing on a 2L

Thank you.

Roy i will get it for u this arvo.

Thanks guys. Since I know have the 8cm we will give it a go and change to the 10cm if needed. Id like to keep the boost to a max of 20psi.

Scotty I'll be running a tial 38mm gate, unless I should go the 44mm? Havent bought one as yet. A mate Rex Kelway is making the high mount T3 external manifold for me in the next couple weeks.

stick with the 8cm like roy and i mentioned. Roy's explanantion is on the money.

Go the Tial 44mm, safe option and proven to work with the combo!

Ive thought a lot about getting a Kando with the T2 housing and hanging it off the housing. Could potentially work really well.

I just prefer to go bigger, housing and gate. Less restriction is always better but there is of course that lag penalty. I have never driven a 300kw 2L but I can imagine it would come on late.

Split it and buy a 40mm Vband gate, realistically they should all work fine.

It was making 270rwkw on 18psi on the old turbo set up. Full boost at 3800 and peak power at 7700rpm. Drives very nicely for a 4 banger, plenty of torque. Positive pressure from just under 2000rpm.

Ill give the 8cm a crack and maybe grab a 44 mm tial if I find one at a good price. Was thinking about a turbo smart 40 but they seem to be a heap dearer than a tial gate.

Here u go Roy, is this what u were expecting fc4a2eb7.jpg

Thats helps loads. Thanks. I am assuiming ts on 98? Is VCT on? A friend wants my TD06-20G when i take it off in a few weeks and trying to find some results to show him to give him a reliable feel for what he will be able to get out of it

Yes this has VTC on and is tuned on 98 octane fuel.

So I was on ebay and had a weak moment...

...Poncams should arrive later this week :)

Glad i am not the only one that did that :P

But the price!!! So cheap!!! Hard to say no.......

256/8.5mm or 260/9.15mm???

This will be real interesting. Just remind me, do you currently have cam gears? Do a run before the cams go in and tune to get the latest and greatest run for reference. Or not....if its going to cost dollars or agro

Would be awesome to see the before and after difference... I've been searching and there is no real back to back comparisons i can find.....

I think the Type B 260's are the best for a Kando yeah? (I am only learning as i go and from what i have read they are best for Mid-large turbos??)

R33 RB25 only come in 256 8.5mm, I think you will find the 260 9.15mm are for the NEO solid lifter head.

I currently have an exhaust cam gear retarded 4deg, I'm under the assumption that with poncams 0 on both sides is the best so will most likely set and forget.

We have the before runs because nothing has really changed since the last tune, unfortunately it wont be a direct comparison because I'm also going from Nistune to Vipec (AFM to MAP) at the same time.

Hoping for a extra power everywhere above 4000rpm and maybe a tad extra down low :)

    • 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.
