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.......

...Poncams should arrive later this week :)

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 so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.
    • Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up
    • Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.
    • We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
    • This is mine, works a treat for the cars, suction is good, I use the Bissell clean and protect stuff I have found giving it a good spray and light scrub with the soft brush on the head of the nossle for carpet, and a rub with a microfibre for cloth seats and cloth door trims, prior to another quick spray before vacuuming it up works the best @GTSBoy You would surprised on what it gets out of carpet and seats that actually "look" clean, I recommend that you test drive yours when you have a little time to kill, then post pics of the muddy looking water that I believe you will find
