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

A little? lol... A LOT!

I just wish I new where to start, it's got everything it needs to make a decent number, but it's knock restricted.

When jez tuned it last the exhuast was way to small, now that I've got a bigger system coming from jap and I made some 3inch tuned length front pipes into a 4inch merge. The exhuast issues should b over, so it's back to jezza's shop to c if there's any gains.

Strange thing is, I had a 4inch system made, and we chucked it on the dyno, only got 7kw gain with adding timing and boost.

C what happens, maybe we need to play with the cams, or something.

Depends what manifold you get.. The Full race one I have was designed for fitment on 33/34s. Tried putting it on my 32 and the compressor fouled on it..apparently full race have rectified this for 32s now

A/C didn't work anyway so I'm not too fussed, then again I may have wanted to fix it one day :s

I saw a dyno graph from a famous 32 on the weekend. It's now running a Precision single (6766 I think he said). The Precision shits allover the -5's for response on the graph, and from his times, on the track too! The 32 is still 2.6 as well so these turbos are obviously a good thing!

Correct! and yes WOW! it has me thinking the EFR's are on their last chance... :yes:

I've already emailed him to find out exactly what version he has on the 32.

The 34 is running one also, however he likes the one on the 32 better.

One thing he did say to me was to buy bigger than I think I'll need and I won't be disappointed, they are that good.

I would choose a Precision over an EFR any day. . .too much hype with the BW's. . .too many results to look away from Precision. . .sorry, but a 2-year wait on an EFR is ridiculous. . .

bri73y.. .do you have a chart for that r32 running the 6766? I'm running this on my FD. . .sounds too good to be true that it would shit on the -5's. . .

No sorry, it's not my car, although it has lived in my garage for a while previously. Damn should've stolen bits off it when I had a chance.... :whistling:

Any email back? The one on the 34 did look a little bigger but by how much I couldn't say. I'd love to know!

What do you think you will order for your car John? 6466?

Hey Joe, or anyone for that matter..

Is there any evidence that the Full Race Manifold is worth the cost vs 6boost & ETM etc being about double the $ ??

Will wait and see how Piggaz's turns out, as I also have a 2.8, been running a TO4Z for a couple of years on stainless china manifold, time to get with the times, with a good manifold and probably a Precision..

wouldn't the one Jez is running, with 30+ psi on a 2.8L with cams etc see 450-500rwkw ? with awesome responce .

Fixed, no need for new turbo :)

Well it made 436 on a 2.3 SR with 24-25 lbs of boost on the same dyno as i made 425 with -5's. It beat my setup low end and pipped me up top. I'd love to see what it would make with 30 psi!

If the 6466 is too big just rip it off and drop back 1 size. Little touch up and away we go!

Honestly mate don't know if the full race is better or not. Would need to do some back to back testing which would be a real pain in the ass as you would need to plumb up 2 different sets of gates.

If I had my time again I would probably just bought a 6 boost one for reasons such as

1. Cheaper

2. Quicker to obtain (each fullrace manifold is made On order)

3. If it cracked or failed in anyway would be easier for warranty

4. The full race is a bit of a nightmare plumbing wise.

Though I do like how the manifold looks and how it makes the turbo sit towards the front of the car.

I also had to cut a bit of the re enforcement out of my bonnet to fit the Massive frame of the BW

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By 180 wanabe · Posted

      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?

      Blow Off Valve Is Causing Car To Stall!

      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'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!!
