looking at buying my old mans 33, he is old and fussy so i know its been well cared for, what more good reason to do it?

its a practically stock 95' R33 auto, it already has a microtech comp in it, and a cat back 3'exhaust and split pulse dump pipe, now i am plannin to add FMIC, 3"front pipe+3" cat, highflow turbo, injectors and larger fuel pump, could these mods see me too atleast 230rwkw and possibly upwards?

cheers mick

looking at running around 17psi i am sure the highflow would be in about the meat of its effeciency at this point. no way am i feeling down about an auto. got a VL turbo in the shed with 300kw thats a 5 speed and would much rather an auto in it,

boostd-its a 4 speed auto, how much power did you have to run 12.2?

id definitely get an auto trans cooler and a temp gauge installed next if you plan to be giving the auto a bit. the heat kills the boxes. with a shift kit/valve body upgrade they are unstoppable.

the mods you listed should see you into the 250's quite easily.

The 4 speeds are stronger from factory so u should b able to run that power without cracking the trans open...and a trans cooler would preserve it some more.

I did that time with 244rwkw a 2800rpm stall and cheapo chinese street tyres.

when your going around a corner and your not on the throttle much if the revs are going down it can change gears on you- so if your just just hanging onto the corner it will spin you out of controll and its pretty hard to catch.

what do you mean?

wrong...

my s1 r33 auto has never done that once in its life, and will only kick back in gears at full throttle, or if you drop down to below about 20kmph.

they are a very predictable trans and i highly rate them once there modded....

thats why i asked for it to be explained, it hasnt happened to me. it wont happen if you know how to handle the auto.

you can predict when it will kick down.

playing with the TPS can adjust the kick down (although you wont get 100% throttle), but not completely stop it.

i was asking about the track killing the autos from heat. does anyone have any tips besides a tans cooler and a temperature gauge?

Sorry, what I meant is if you are going sideways in a manual and slightly back off it will reduce wheel spin and straighten up in a controlled manner, however an auto on backoff lets off alot more on slight throttle decreases due to the stall convertor and causes snap back. Mine has a high stall which I'm sure makes it even worse.

what do u mean wrong, mine has done it before. what you talkin about u clown don't just come on and say someone is wrong maybe urs doesn't do it but i know personally of four cars that do

you and your mates car may need a trans service and some adjusting.

the skyline should never kick back a gear unless you want it too. as i said before either by flooring it , or by slowing down to around 20kmph.

If your trans is downshifting at speed with no throttle then you have some other issues that needs looking at.

as suggested TPS, fluid level etc.

it all comes down to practice.

with the auto you need to drive thru the slide and power out the other end.

while with the manual you can more play with the throttle and feed it on and off thru the corner.

both work well but you need to adjust your driving accordingly.

If your car will spin the wheels in drive then it becomes easier to control to a point , at which you get to much forward momentum and then that creates its own issues.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving.

      What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
