For a hunk a crap engine they sure sound nice. This sounded so nice for what was a modded factory engine.

Grand-Am Rx8's FTW Some more, plus the Reily MKXX

Single plane crank V8's just dont do it for me

This is why quite a few of us are skeptical, Of course a demo car is going to have brilliant results, you also said the boost held dead steady at 31psi, when it was the dyno MAP sensor maxing out. I can understand you are trying to make a product you sell look better than anything else, but we are the ones that need to do real research if we are to give you $2000 for a new and relitivly un-proven turbo. Guys selling Ebay China turbos have great dyno charts as well, but we never get the full story in their advertisments. I don't think E85 is that hard to understand, Uses more fuel, makes more power, costs 2 Grand to set the fuel system up, Costs 5-600bucks to have it tuned, Cant get E85 in the middle of bum f**k Idaho, long term it will corrode fuel systems unless you spend more money on making everything Alcohol proof. Can you see why some of us don't want to use it? Guess not because oh look it makes 400kws It must be the best thing since sliced bread.

Considering that you can get a genuine 500rwhp with standard RB25 cams, I dont think it is worth it at all unless you want more than that. As for the Neo vs R33 setup, the ports are the same, valve sizes are very similar if not the same, only advantage between say a 256deg 8.5mm lift cam for the Neo would be slightly more agressive ramp rates on the lobes, and thats if Tomei even bothered to do that.

Where the hell did he get an RS500 in 1992 in Aus!!@!@ Mebbeh I dont wanna know lol!

Use the bolt holes that are already there Might need to be a little creative though. I have also seen aluminium brackets welded to one of the covers

I think this also, so you burn ~30% when just cruising, but wind the wick up and gain say 40rwkws over 98, you now have to add fuel for the extra power, so despite gaining more power you are going to use a bucket load more fuel at WOT on E85 than you would being in a less powerful PULP car. Anyway this isnt a fuel debate its about the Precision Turbos. Which like I have said they make plenty of power. But are they suitable for the average Joe Stock R33? For a standardish RB25 I still think It would be hard to pass up an Internal Gate GT3076 (preferably in HKS GT3037 Guise)

They also had to change the turbo after every round if they were lucky enough not to break one during the race. By club level race cars I mean cars not designed to do 1 or 2 hot laps a session. If that SR20 didnt break, would you have taken it to EC and done 10-15 laps flat out running 33psi on a 30deg day? I sure as hell wouldnt. To me a car lasting a couple of dyno runs and a few passes down the strip doesnt mean an engine is proven reliable on E85. So now the Journal bearing turbo is different to the ball bearing one? how so? Different wheels/housings what? A bearing type wont effect power output by more than a couple of KW at the most.

You can still use the S1 RB25 coils with the X6 box, will just need some wiring done, or if you want to use to coils you have, make a couple of brackets and mount the on the intake side of the motor or on the cam cover.

Its through Shannons, a couple of guys in the NSW club have it

Just to add, I feel that a modern turbo should not need 25-30psi to make decent power. Just seems a little "old school" to me. Like the Group A sierra's needed 35+psi to make 550hp using the TB34 group A turbo

I can think of quite a few, lots of cars run a 3076 (not quite 570hp I know) and plenty run GT35Rs. What I was trying to get at was how many do you know of that are running 30psi? Justin's 5557 RB25 result doesnt give me confidence, but that is just 1 result, once there are a heap I can guestimate average power, Eg there are heaps of GT3076 RB25 results showing circa 300rwks at ~18psi on a stock RB25 The 5575 made a touch over 250 at the same(ish) boost level. But who knows the next guy to do it might make 350 at 20psi.

Keep the "rolla for shopping centre car parks or if the skyline needs work done. Plus you can get limited usage insurance on the skyline.

Any reason the main hoop sits so far in from the pillars? or was that part of the old cage? Dry sump setup looks good, but I am very suprised the car didnt have one already?!?

Oops I though I read Twin cam 30 lol. Bah, read it anyway lol

Just use a bit of Stereo amp wiring and bolt from the engine mount to the strut tower, but keep it away from heat.

Read the 300odd page thread, everything is covered in there.

That sound a little better Bit big for what I want though (stock 1jz)

So from what I can gather here, these turbos are great for drag cars or dyno queens, street cars or club level circuits cars not so much. Im not denying the fact that they make awesome power for their frame size, but the boost required to do so makes me think twice about using one. PJ do you have a dyno run of the SR20 5557 combo at say 1Bar to 1.2Bar (pretty common boost setting used in unopened RB's and SR's)

LOL @ 600rwkw circuit car! Marks car has I'm told around 520kw at the treads and it's is on struggle street putting it down with some of the best suspension/tyres money can buy, let alone having another 100hp. But you say that it will be mainly E85 to run 9.5-9.8:1 it would have to be ONLY on E85 you wont get away with PULP and 9.8:1 unless you rev limit it to 4k rpm and 2psi. Oh btw will this be 4wd (GTR) or 2wd? Doesnt say in the thread anywhere

^^ He runs the RE0xxx its a built factory Nissan Box out of some 4wd V8 sedan thing (cedric or similar) He runs 8's on it.

Needs less Nissan and More Alpina tuned 3.4L BMW six Nice car, lost its appeal to me when I saw the RB25 though

Now it looks how a Lotus Should!

Have a listen to the Panoz Roy!
