But isnt that the point. The original poster is talking about shoudl he throw a 30 bottm end in his car. He hasnt talked about changing cams, turbos etc...so he is simply moving his power brand down 500-700rpm. he is talking about track days, not competition and just wants to do them reliably. You then talk about people with a normal budget...well a built 26 bottom end needs pistons and bearings, std crank and rods can do the job for a gob of power. If its an R32 sometimes there are bonnet clearance issues etc. An RB30 bottm end is going to most likely needs rods as well as pistons...need sump adaptor, more machine work for the head studs,. mod dump and cooler pipes....If you want to spend the extra cash and have the extra headroom for future power mods with bigger turbos etc..But the tone of the original post suggests to me best stick with the 2.6L. He said it was responsive as is. HBut he also said budget isnt a concern sooo... present both side of the discussion

Meh...Mitsubishi have not built a good car since the GSR Sigma

Fatz had them on his GTR running 324mm Brembos. They needed a spacer to clear the offset....not sure they would clear radially though with 343mm Measure the min ID of them and I will throw my Alcon Mono 6 over my 343mm rotor and get a diameter for you

Some 17s ... not all 17s. Based on my experience with 343mm setup and CSC calipers, AP CP5555 and F40/50 calipers and 343mm rotors thinhs like AVS Model 6, Work XD9s, 57 Gram Lights, CE28s etc wont fit inside 17" wheels. Teh CE28s fitted but not enough clearance Things like Weds, LM GT4s, TE37s etc will do it easy. I have not tried them but people seem to enjoy some luck with Enkei RP-F1s etc If you want to guarantee fitment inside a 17" wheel then you need to go 332mm rotor

I am not even going to be up there to make sure everyone is too drunk to drive back Monday morning

Yeh...for me it comes down to driver briefings. Traffic management is always a tough thing. And quite often its the so called experience or quick guys that are absent minded when on their slow laps NEMO https://www.youtube.com/watch?v=pZJ6VAfIHu8

I will say it. The AWD does make it easier to grab a lower gear and rag on it out of exits. But I understand your point. I am yet to see where having an RB30 makes the car measurably quicker on the circuit. I would be very interested to see someone that kept the same turbos and head but only changed to an RB30 bottom end whether they would be quicker at the track...I think the lowst revs I pull at the track is Sandown turn 4 and I am still at 4,200rpm in 3rd....so easily able to grab 2nd but your point about drivability means I try to hold 3rd. If the RB30 is still ahead of the 26 at 4,750rpm when the show is all happening with boost in its guts and can hold on to 7,800rpm then I guess the RB30 is the better option.

Thought the main one that is covered in Option mags/dvds was November

Note sure you can charge for oil downs etc. The cars by nature are ticking tiem bombs sooo. But if you wan to put in far more robust pre-event scrutiny weeks out where the scrutineer can tell you things like - unsupported oil coolers - oil-water-electrical lines through panels with no grommets is a no-no. - no overflow for cooling systems - exposed coolers and lines/harnesses in wheel arches - questionable integrity of aero and fitment of panels etc etc then go for it. From my perspective anyway most oil downs I have seen could have been pipcked up before the cars went out...typically not from rods out the block

They put the one they made in a Nissan box and showed the scrutineers. Not like any one knew what the cars had back in Japan anyway.

Something I have noticed , and it was easy for me as only running a 2L RB20 with TD06 I gave away displacement and sometimes power to cars but give or take had the same gearing. You come out of a corner at a certain speed...not a certain rev. So if cars both come out of a corner at 70km/h and a car with an RB26 makes its power from 4,500rpm to 8,500rpm and the RB30 makes its from 4,000rpm to 7,500rpm....well my money is on the RB26 being quicker irrespective of torque etc etc Especially if it can hang on to a gear longer. Thats assuming you have simply thrown in an RB30 and running same wheels and gears. If you cant rev the RB30 as hard as you can the RB26 then I dont think you can automatically say the RB If you go RB30 and drop a gear ratio and you can use the torque to push you along then so be it. And for those talking about reving an engine to the moon. A) its fun. WAAAAY more fun then changing gears at 6,000rpm like you do in a say a typical V8. Hell my Cossie has a limiter at 7,200rpm and I really miss the extra 1600rpm my RB20 gave me. B) you got a shorter stroke or if you are lucky and have a narrower bore and lighter piston then revs dont hurt an engine more then a bigger engine pulling less revs. At the end of the day its the metallurgy of the crank, rods and pistons and how you oil and cool the thing. I agree that you want to make as much power with as few revs and boost as you can make....but do the numbers on stroke, piston speeds and rod lengths etc before saying revs are bad.

Why does it have a circular opening in the flange to the turbo ? Seems odd? Also, the fact that the GTS-R and Gibson manifolds are tube not pipe, means the resonance from them will be different. If you want MAX banshee than tubular manifold will be the pick. not one out of pipe bends

Ahhh ludicrous speed! The result of ludicrous ;power. Love it!

Sux to be Felix Da Costa right now....but he has hurt his rep with a scrappy year in WSR. Hope fresh fish smashes JEV Imagine being 19 and a GP3 driver getting pushed into F1

Ouch...looks a pretty bad accident. Nice of the guy to stop but not sure it was the smart/done thing.

So the ARK R32 GTR that missed lasts years event has gone to the graveyard of cut up cars? Alos, I have seen pics of the black Supra, Gorilla Ind or something. Always liked the car as it was quick and still looked like a street car....any idea how it ended up eating wall??? Major damage ?

Good work! What is your best PI time? Do you agree with the theory that generally if you do a 1:42 at EC then you can do 1:43 at PI. Generally about the same or a second or so slower at PI?

There is nothing wrong/ to worry about re oiling with rwd RBs

NOICE!

I can see how that could have been a highlight

Testament to do how strong they can be when you give them the right gear and tune them well. Credit to you and the posse working on it!

So this is what GTR oweners do with their Fridays when the rest of us are at work! You are dead to me!

Is it still the std headgasket and original motor? Your cars always kick a55! Glad you are an R32 owner and dont fiddle with 33s

Do you know what housing flange - A/R it is running? There is not a lot of space in the Sierra engine bay so prefer to run internal gate and smallest frame turbo...hence why the 7163 seems an option.
