The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

For a single entry that is very impressive.

(looks at T51R) :ermm:

Yep I reckon the PT6466 CEA is Precision's best moment, it basically always seems to deliver - the better the setup, the crazier the result. Looking forward to Scr48's result... should drive very nicely on a 3litre and obviously the potential is there for massive power, even the .84 will make a lot but if it ends up not being enough then going to a 1.15 hotside would allow for unrestrained silliness :)

I'm not 100% sure yet, but one thing I am not sure of is if someone puts one on a high flowing RB (ie, RB30 with aggressive headwork and cams) if they will flow enough per psi to keep the big engine happy - they seem to be keen on high pressure ratios for their power, but that might just be the cars they've been on so far. Thats the only reservation I have at all, and it may not be justified.

Man the precision turbos appear to be the best bang for the buck. I know EFR and VGT are newer but you can't deny living proof!

FP HTA are very real competition, the 6466 is a particularly good offering however - but from FP you have the "rest" of the awesome turbos. Some of the best value for money turbos I could think of for small/medium sized engines in order would be (some real rough and realistic E85 power ranges):

FP GT3076R HTA - For 330-380kw @ wheels

FP GT3582R HTA - For 370-450kw @ wheels

FP GT3586R HTA - For 430-500kw @ wheels

Precision PT6466 CEA - For 500-600kw @ wheels (basically it just seems to do so much so well!!)

FP Super 94 HTA - For 580-680kw @ wheels (same as above - but larger scale)

Those are my favourite considering price, reliability, fitment, spool and power.

the 6466 is popular with the Supra fans so there are some results for 3.0L motors but results on the RB26 are pretty hard to find. The general consensus from what I read was don't bother with the 6766 as the 6466 is so damn good and punches above it's weight.

Our set up still has more in it, I've heard these turbos love 35psi+ so when we get it to hold spark we will go back on the dyno to see how it goes.

You and me both! Hopefully Friday!

Capacity: 2.6L

Comp ratio: Standard

Cams: HKS step 1's 272 8.7 lift (I think)

Exhaust: 4" dump into custom 3.5" exhaust with no mufflers

Will be tuned on E85 from the drum, the car is not my daily anymore and for $2,50/L I don't have to worry about watching the fuel prices jump up and down.

Because I'm not sticking with RB26 and don't wanna upgrade ECU's again.

Will utilize some of the additional channels from the PS2000 in the future.

A couple of people have also asked why the Logger IQ3, it's for same reason. buying now to setup so I don't have to replace in the future.

My aim is just to have a bit more poke when I press the accelerator down, I'm not chasing a power figure nor am I looking for a world record.

So finally got around to getting my car sorted, only to run into more problems.

I ended up with a Platinum Pro BNR34 specific model, and 3.5" dump not a 4"

Everything else above was fitted and turns out should've updated the valve springs too, thinking the 272 drop in cams would be ok with stock valve springs.

After a problem with the CAS & Valve float when you add any boost the car will be getting some supertech springs & possibly a Ross trigger kit and heading back for more boost.

What I ended up with was 494hp @ 13.5psi

I'll post up the dyno sheet later tonight when I get home and take it out of the car.

Another upgrade I will look at will be updating the coils or fitting a CDI & pencil coil kit

The 6262 sounds great, spools hard but I can't wait to get some boost into it.

The goal is still 20psi, I have no real power figure aim but judging on what it made @ 13.5psi its gonna go close to or over 600hp quite easily.

I'll keep everyone posted,

Cheers

Took a snap of the graph from the 6466 on the RB26 that JEM tuned the other month.

Soooo much midrange for the power output.

That is crazy, still 2.6?

Paul, I hope you are going to plot this for reference :)

I've done a quick eye plot ;)

I'd love to drive it. Dyno only tells half the story.

Errr and I sold those exact turbo which I was gonna put on my own car :(

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
