Precision Billet Turbos


Recommended Posts

not suprised, being auto...my 4294 with a .91 T6 housing wasn't any laggier than a 3540 1.06 on a RB30 single cammer really with a auto

only a split second was a 3540 better and then the 3540 got fiercely trodden on...

agreed that drag+auto = a totally different ball game when it comes to response. its got very little in common with response on a street or circuit car.

have had a 3076 on an old school 4 pot feel as responsive as a T25 SR with the right cam and stall combo. easy to do, just useless around a bend.

I had a 35r on a 6boost mani, I changed to a new 6boost mani and 7175, and it is more responsive In every way, makes more power earlier, power doesnt drop off, and builds boost on the tbrake significantly faster....

Must be moving on from older technology that did it...

Tossing up between a 6262, 6266 and 6466 on a stock capacity RB26... Looking for good response and 400-450rwkw on moderate boost 20-25psi

T4 0.82 divided rear... Want most of the boost all in by 4000rpm

Also is everyone just going journal bearing or running the ball bearing? I don't mind the extra cost if it's worth it

Well after Jez's result on his standard 26, it'll be hard to go past the 6262. He made 402 at just over 20 -21 psi IIRC.

I've seen some photos of the 66mm cea turbine next to their older stuff... I'd be highly tempted as the aero looks great.

Question in my mind is 62 vs 64 compressor in terms of lag. Id be tempted to just go a 6466 for the headroom, coz u know u will end up with a dirty 30 lol

When I was comparing my 6466 to a 6262 a few weeks ago, the angle on the blades looked a little different but also the gap between the blades on the intake were signicantly more of the 6466. Both were CEA's

Hmm thats indicating its more than just a change in trim, the 64mm comp must have a way bigger exducer than the 62mm so its more or less an entirely difference turbo.

Like comparing a 3076 and 3082 I guess. Same stuff, different application entirely.

A link to a page with comparison to old tech 65mm wheel (I think the 62mm turbine is same tech) and compared to new 66 CEA turbine:

FYI both 6262 and 6266 are rated as 700HP items. I'd be chasing that 66 CEA item, better tech is where its at.

Finally got the 5558 in today, can I use any 3" v-band flange off ebay (exhaust/dump side), and what oil line/fitting did you guys use - do I just go to Pirtek/Enzed or get an ebay jobbie - re: Kando lines fit? I am not sure if you just connect the oil line to part way in the existing line or get rid of existing and new one straight to block? thanks :)

    • So next year I am looking at upgrading from my VE SS bomadore ute to something more refined.  I wanted to stick with a V8 but not anything German or Australian, either a coupe or a sedan. So if I wanted anything newish that limited my options to either the Lexus RCF which I quite like. But with the price they demand and a kid on the way a 2 door coupe is probably not going to be the best idea. The next best thing would be the ISF but the newest models are 2014 and commanding over 60k and even the older 2008 models in ok condition starting around 35k is kind of bullshit. So I figured if I could not have the noise I could perhaps make do with easy power. Enter the infinity Q50 or Skyline equivalent. The price difference between the 300 and 400hp models seems a bit crazy. Right now there is 300hp Q50 one on carsales from a dealer with 61km for 27k drive away. If I wanted to get a 400hp Red or 400R car the prices seem to start at 43k From my limited research it seems that the only differences are that the 400r/Red Red runs more boost and a more aggressive tune. There are are turbine speed sensors on the turbos. Has 2 pumps for the water to air intercooler. Runs an engine oil cooler. I'm guessing that the exterior trims might look a little more sporty as well. I had a lazy look for upgrades to bridge the gap on z1motorsports They have kits that upgrade the water to air heat exchanger as well as the coolant pump which should give a non Red/400r better intercooling temps than the stock Red/400r. I added an engine oil cooler with a thermostat as well to try and make things as close as possible. Obviously the ECU is going to need a tickle. Having not done much in the way of research they also sell a ECU flashing tool with pre loaded tunes that are supposed to boost the non Red/400R by 100hp which adds 1k USD to the cost. The total cost of the parts @ the current time including shipping and taxes worked out to be $4350 AUD. Personally I would rather get the car tuned on a dyno which would probably add more cost Assuming the worst that you got a workshop to install the new parts I would guess no more than 5 hours would be required in the worst case @ 5 x $150 per hour = $750 So the total cost could be around $5100 So for easy number 5k + 27K = 32k I guess that would leave some change left over to swap out the open diff and fit a LSD Any thoughts?      
    • Right, not sure why I thought it to be a lean spike. It might be fixable with modern card-style hot film MAFs which have some design features to avoid counting reversion flow but I've never tried it myself.
    • I did not realise this, I'll contribute more and earn my stripes and retry later. 
    • I'm only going to hassle you for posting links to images. It's against my policy to click links that could be some nasty payload. Sadly, you need to make 9 more posts before you can just stick the images directly in a post, unless @PranK sees this and bends the rule for you.
    • Hello,new to the group, I bought a R32 from auction recently, wondering if anyone knows the cars history, seems to have the usual go fast bits on it, plan is to do an engine swap- add 2 extra cylinders and 1 extra turbo. https://www.dropbox.com/scl/fi/i4rjmlzubjbwjtguh6f4s/IMG20241011140744.jpg?rlkey=q0lumm251377vknbqktfwrycq&st=7scvwx4e&dl=0 https://www.dropbox.com/scl/fi/ro24qmwzlczzlfsr4y05x/Screenshot_2024-10-10-10-49-23-90_9a2f5bb2149dae94cd1e190effc09b33.jpg?rlkey=oyguh26ttshlf04ccp48odf4v&st=xloae97b&dl=0   New to forums and posting pics, if links don't work, take it easy on me, 42yrs old and I tune carburettors!!
