If you do have a 2.5" exhaust, its not a problem. Make sure its mandrel bent, and free of restriction and itll probably do better some of those restricted 3"s out there cause theyre so loud. "Maximum boost" rekons you can easily flow 400hp (read more than 400, i think it was closer to 450 but i have left my book at home in oz so cant quote) with 2.5" and doubt with a 2530 or the other turbos talked about here will make this. People need to stop thinking 3" is the all and one all size.

I read the link before you posted it, it doesnt really answer my question. A locker will lock both up when decelerating hard (same as 2 way) will hook both up all the time when accelerating (like all lsd hopefully) but a locker wont go around a corner without letting you know about it....will a 2 way be also a bitch like a locker and if so, why not just weld your diff??

Whats the point of these LSDs if theyre so tight and you cant go around a corner without sounding like you have justed welded your diff? I have a locker, it does its job, but Im sick of chirping everywhere, chewing tyres and was hoping to upgrade to a nice lsd...but if theyre going to be like a locker whats the point?

So is a 2 way diff the same as a locked diff? Do circuit cars only use 1.5 or some use 2? Why is 2 way such a good drift diff and why is 1 way no good? Afterall, when youre going through a corner and dump the clutch, your accelerating... Is it because youre on and off the throttle all the time for example one point through the corner youre acclerating (1 way spins both) and then you back of a bit (in which 1 way and 1.5 way would revert to spinning one wheel???) and then back on, (1 way back on)...??

This cooler is 600*300*75 mate. Theyre a copy of hybrid, not apexi. Also, can get them for $175 from justjap delivered if you mention youre a nissan silvia member. Amazing how these coolers are bought buy everyone, and then sold as "whatever they want them to be". One place on the cold coast sells them for $600!!!!!! Haahahahahahah

Microtech's arent that bad!!!!! Walbro's are though. With that gold turbo and 25 psi are we making 360rwkw or 360rwhp? I hope the former. Dyno sheet? What has been done on the engine? What type of ign advance are you running on 25 psi? Sounds good.

Thats what I thought doug, I really want to get this sorted before i get this car back onto the road and head for the strip. Any suggestions into tyre sizes please, rim size and what tyre (street-legal) Thanks

Is it air-related? My turbo turbine got hit by a mud wasp's nest after I went for a bash against a GTR a couple of weeks after I had put a new manifold on (the bastards layed their nests in the exhaust ports of my fj overnight when I hadnt had the manifold on and I didnt check inside the ports... but i had a damaged turbine which whined when coming onto boost and it didnt sound nice. No burning smell. Glad I got rid of it though.

Is the gearbox from a 25det? Is it series or series 2 (ie push or pull type)? Can the yolk come with it? What is the reason for sale? The clutch, did you buy it new? It looks to have heeps of hot spots on the flywheel. Thanks

Just before you go taking the head off do a compression test. I remember once a 180sx doing this only at idle and it wasnt a HG. (never knew what it was)

Car is a street-registered 180b datsun. Aim is for fastest 1/4 possible on street tyres. Car has fj20 with about 400rwhp with another engine getting built for more power. I have modified the read end so it sits at 0 degrees camber with 9inch rims at the back which has currently 255s. They are 17 40s. (1) Should have I just run a 13 inch rim with a 225 street drag tyre with high profile??? High profile seems to make straigth line performance great. (2) If I keep these 9inch rims and go to a MT street drag radial tyre which is what I want to do, do i keep the 255 or should I move onto 275? Any other info appreciated without input about suspension as thats another story. Cheers

Please let me know if you have either and pricing for each and most impt condition and reason sale. Prefer gold coast brisbane area. I am on the gold coast. My car is off the road until i find one and thus is the reason for buying!!! Cheers

so what about this porsche then? Also enriched to cool valves down i suppose. It looks sweet Why is it i can never see flames from my gate? It vents to atmos...

This was posted quite a while ago in this section I think and I still like it to this day One thing I dont get, why are there always flames? Is there always that much fuel unburnt on load? (makes sense i suppose for a road turbo car running 12:1, dont know what f1s run).

How about stainless steel dumps, coating and wrapping? Ultimate I say.

Infinate....with an exhaust valve

Totally agree with everything below though I think the wolf is about the 1100 mark (that said it doesnt compare to the pfc and i would never recommend it even though i have one). My bad regarding cost and AFM + CPU.

Just because an engine produces 369rwkw with an AFM doesnt mean the AFM isnt causing a restriction and that there is nothing wrong with the AFM as you say. Your logic is to look at the end result without a proper control (ie no AFM) which is nothing but inviable. Honda and certain toyotas run MAP. Have you driven a vtec-powered car? Youre always the first to say if its not needed than dont buy it. Well what about this case? The afm isnt needed and unless youre a track racer where a split second counts the AFM isnt needed at all. He can save himself money on not buying an AFM.

Screw the unicorn or whatever other animal you can think of. If an rb20 wants to beat any other engine possibly known to man it needs help, and the help it gets is from the hippo, dance dance dance boys and girls and the hippo PWNS you.

The brand i use is Exhaust gas technologies. BTW (sorry for not replying to your first thread). http://www.exhaustgas.com/ProductDetail.as...tID=&RepID= I just log with my lm1 innovate kit, but you can simply use the analogue faces or simply monitor voltage 0-5V with any instrument. If your a gun with jaycar stuff, you could get wawy doing this cheap. The sensors are the expensive bits costing 48 each american. Ill be in the states soon

I agree, but I started this thread for those who would like/can go one step further. There's no denying there's an advantage and for the competitive, every bit of torque and HP counts. That said, EGT sensors dont cost 1000s of dollars. For a few hundred you can have a system setup on a 4. If you get your car tuned by someone, then it shouldnt be much more expensive. The engine is a linear device and once you have a few load points tuned with respects temperature for each cylinder and overall AFR, youre away. Its not as expensive as you make it out to be. However, as I said, totally agree, for the average joe who just wants to fang his car, its not worth it, however for the competitive its something you shouldnt disregard. You mention a 400rwkw rb26, I know I would have my AFRs spot-on for an engine of this calibre, not only for power's sake, but reliability though you claim these engines are reliable with one sniffer, I wouldnt take the chance. This is not a motec system, just four EGTs with analogue faces, not that expensive.

When it comes time to tune a car, most simply rock to the dyno tuners, hand the key over and leave it at that. Most of the time youre happy with the result. But chances are, you are not getting the true potential out of your engine. Most tuners simply use a wideband sensor shoved into the exhaust and monitor collective AFRs. While this works, it is not nearly as effective as running one sensor per cylinder. Gains of HP and engine longevity i beleive are almost always had with one sensor per cylinder. I doubt that any inlet manifold distrubutes air evenly across each cylinder and hence we have the potential for each cylinder to run different AFRs. In addition, fuel injectors never flow exactly the same adding to another source of AFR variability. Youll often hear that cylinder number 4 goes on 4 cylinders and that is simply because I would say the inlet manifold almost always forces more air into this cylinder. So if you can afford it, get four sensors in there and get the maximum engine power and safety. Or you can go about it another much cheaper way. Simply fitting EGT sensors to each exhaust runner and getting them all to run the same temperature aiming for your 12 AFR or less if youre running big boost. I will be posting some results in a few months of my experiences and gains with such a setup (I went the 4 EGT sensor route). If anyone can add info it would be great. Also, I used Exhaust gas technologies sensors. Are there any cheaper ones out there on the market which are as good? Innovate have released a cpu that logs 12 wideband sensors but beware, its expensive. Look foward to your replies.

Searched and cant find an old thread on wolf3d showing what each load point corresponds to. Each load point is summed in the single column on the left starting from 0-107. Load point 0 = -80 and less kpa Load point 14 = -60 to -79kpa Load point 21 = -40 to -59 kpa Load point 28 = -20 to -39 kpa Load point 36 = -1 to -19 kpa Load point 43 = 0 to 2.34 psi Load point 50 = 2.35 to 4.69 psi Load point 57 = 4.7 to 7.04 psi Load point 64 = 7.05 to 9.39 psi Load point 71 = 9.4 to 11.74 psi Load point 79 = 11.75 to 14.09 psi Load point 86 = 14.1 to 16.44 psi Load point 93 = 16.45 to 18.79 psi Load point 100 = 18.8 to 21.14 psi Load point 107 = 21.15 to 23.5 psi Notice the positive pressure increaments for each load point is 2.35 psi. This is what I have measured on the street. Can someone confirm the above values are true? Thanks

Im with mattsr and cubes!!!!!!!! Give it some real boost. After all, that GT30R is only having fun at 22 psi and you have engine capable handling more now. Bring it on I have been watching this thread. Beautiful work. Cant wait to see the results. BTW where did you get the turbo from? I thought the "real" GT30R still werent available in Aus.... You know that you now have wet our appetites with pics , so we're gona want some audio clips when its done Ciao
