Its wonderful for suprise adventure driving...seen as though you always end up in a field of pretty daisy's instead of the road you started on.

Have you not read all the posts saying that changing the plenum on a Rb20 is the same as setting fire to $$$$$$$$$$$$$$$ you WILL lose 20% power not gain any.

mebbeh...but I feel like drinking and or sleeping

i agree, these seem much better at lower boost than either the Presision Billet or GTX turbos. Espesially hte Presision ones, which by the looks of all the results i've seen dont come alive till 2Bar. The EFR turbos are designed with OEM in mind so appear to have a broader efficency range than the performance orientated GTX and Presision turbos

LOLFAG!

Some oil "should" have gone through the over pressure bypass built into the factory oil warmer, if you have removed that or a running an RB20 one you will be in trouble

Indeed roy. hers a question, Where does F1 go when Bernie goes? He's no spring chicken. So where does that leave F1? Will it be good or will it be bad for motorsport in general?

I quite enjoyed Superlap last year, waving the chequred flag at millions of bucks worth of cars was fun. But I Personally would not spend that kinda coin on a (pro level) car just for that event, I would rather a slower car and use the bugdet on door to door stuff. Not saying I would never enter a time attack event, If I had a car to do any sort of track days I would be a happy chappy.

Yet those people will happily what a "nice" looking turbo on the side of an RB25 with badly scractched cam covers with no coil cover and wires running everywhere. GTS-R style low mount manifold looks better than any turbo anyway

I ca nsee pro's and cons of having (next to) no rules - Building a car to be fast over 1 lap with no rules is a lot different to building a car to meet strict rules and beating the other cars within those rules ala Dunc running a 20 year old car against evo's and 6L commodores and winning I don't see the reward in doing 1 fast lap all day and winning a 2 day event. But I have always been a fan longer races (le Mans, the burgerring 24hr, bathurst etc) So to me there is more reward in being fast all day and night and winning. Time attack has its place, but is rather boring to watch from the stands, and would be even worse on TV

That reminds me, the 05 Mobil Sierra of Peter Brock was said to have had an extinguisher nozzle pointing at the turbo, was allegedly found by one of DJRs crew chiefs, but by the time the tech inspectors arrived the 05 car was behind a locked garage.

Bringing this back up, instead of whoring the GTX thread. Anyone rocking one of these yet? After seeing the somewhat dissapointing results of the GTX garrets I hope these are better, otherwise I'll be slapping a $1000 Ebay T67-25g on the 1JZ lol I think a 7064 would be mint on a streeter

I've come up with this after the 2011 supercab thread with teams somehow getting an extra few laps from the car without running out of fuel. So what have you seen/heard on the grapvine/read etc, and is it good or bad. Things like the Ferrari F1 4L "fuel cooler" Nascar teams filling the cage/chassis with wet sand so they meet minimum weight at Scrutineering, then over the course of the race it dries out and falls out the bottom of the car. Or in Snowy's case, running the R33 gearbox in the 34 at Targa. I feel that things like filling the car with wet sand is just blatent cheating, but running larger/multiple fuel lines is clever, or running a 5 speed instead of a 6 speed offers no real advantage. What do you guys think

Rated at something like 2000hp, so if a thin wall cast iron block doesnt, than a billet alloy one wont.

Mine would be (given infinate moniez) would be a Bullet cylinder heads Billet alloy block with a 90mm bore and a custom Billet crank/rods giving something like 3.6L, with a CNC ported RB26 head, custom cams, big titanium valves, Twin GT-RS turbos with 11:1 comp and running on E85, and of course Dry sumped...and if we are going a billet block, might as well have a nascar style billet sump with pump incorporated into the pan ala this

They used to do that in NASCAR, have a 2.5" "fuel line" that went round the car. When the tech inspectors were going to measure to fuel capacity the team would fill the tank with tennis balls so it came to just under what was required.

Imo, the .63 housing would hold back the new compressor to much, would be fine for a standardish street car. But It would be missing the full potential. As for the above dyno, thats not much more power than what a GT-RS can give but without the GT-RS response, or its the same as what most people get with a GT2835/GT3071. It isnt making 200rwks until 4750rpm. that might not mean much to some people but its rough guide I use to see how they would perform in the mid range. But like I said if you dont have HKS 2835 money the GTX3071 would be a very nice option, pehaps not as good as the X series could have been but meh.

Got any pics/videos Stuart?

I would rather that than a massive amount of turbulence pre turbo, and dubious longivity of the setup

Its probably knocking, if it were a valve hitting a jam pot there would be next to nothing left. So wait, tuner tuned car with No NVCS then hooked it up and ran it up on the dyno? and it made noises....yup sounds like it was pinging its head off to me. Also I'd find a new tuner if he didnt re-tune after hooking the vct up.

Why not just go a propper twinscroll setup?

Wait....Found a good pic of them, looks like a half decent setup Sorry about the thread jack btw lol

ooohh I remember them now, they have the funny old school wastegate flap thing that I wasnt a fan of.

Are they the new internal gate ones? I remember a thread about them not that long ago.
