they arent bolt ons lol Definitely not the ones Joe showed me thats for sure.

Those were my twins. . .I split the setup (twins/manifolds) and sold it. . .

Precision doesn't offer the rb26 specific turbine housings, you can purchase the 4828's without their hotside (-$100), but will have to buy the 707160-5 housings and throw them on the 4828's. . .as far as piping goes my plan was to fab up some hard pipes all the way. . .

Guys this tread is wary too long, maybe this needs to be closed and a new one opened as i know theres new precision turbos out so makes the start of the tread useless.

Anyways i currently have a td06 25g that puts out 320kw on 18psi full boost is around 4300rpm. I want a precision turbo equivalent but with more response as i feel the td06 is a bit laggy. Also on e85 i hope to get at least 360rwkw :DD so which precision would suit me ? I'm confused with all these numbers..

ALSO i want to low mount it for stealth

HKS 7071 :)

The two sizes relate to the "visible" size of each wheel, ie compressor inducer and turbine exducer. Puts things into perspective when you consider a PT6466 flows more than a T51R Kai, and even a FP Super94 HTA (aka, FP6768) is a fair bit smaller wheel wise while being capable of T51R SPL flow

Are you using compressor maps to compare flows and pressure ratios? .... :P

Haha I was wondering if I would be called on that :-P I'll eat my hat if someone can show an unmodified T51R Kai making more power than the highest power 6466 setups, but yeah I was perhaps making a tall call on the Super94 haha... In all fairness the T51R SPL probably has an outright edge, just there is a fair chance of 90pc of people who use them won't see ever make good use of it.

Highest ive seen with a T51R KAI on an RB26 was 603awkw at 30-32psi.

That's the one with the upgraded compressor that ran at JEM? But yeah, folks have gone over 600kw in Oz with 6466s - bigger numbers in the US but obviously dyno comparisons get a bit iffy :)

Aggroman - there are others that make that sound too :D But yeah, safe bet with a T51R.... it's one of the things that disappoints me with the Precisions, they all sound pretty run of the mill. Yeah, I let the sound influence my turbo (and other parts) choices :teehee:

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
