Hi, New Here. GTR Tech/Tuning questions if i may...
Hiya,
Im very soon about to buy a Skyline (well, after TenOfTheBest, what choice have i got? If u cant beat em, join em! lol).
But firstly i have to decide which model- im drawn towards the R32 but the ATESSA system was uptated thru the years, are the later versions noticably better (will they give a big advantage when doing full bore standing starts in a 500+bhp car?)?
If they are much better, can R32s be upgraded to the later spec ATESSA at a reasonable cost?
The RB26 engine itself didnt vary at all through the R32/33/34 models right?
The turbos/Intercoolers did, but they will be changed anyway so no matter.
Is the engine managment more sophisticated in later models? (Not better mapping, i mean a different, uprated ECU)
Apart from the clutch (which on all big power modded cars will need to be uprated), how does rest of the std transmission stand up to big power and full on launches? (i understand the silver R32 at T.O.T.B. had a std transmission?) You got the gearbox, and front, centre, and rear diffs right? Or is there more in the transmission due to the ATESSA system (which i dont fully understand, does it work by a computer controlled secondary clutch in the centre diff which varies the power to the front wheels? If so, i guess this clutch also breaks yea?)? Like i said- HELP! Need tech info asap!
Also, what kind of power is achivable with a std bottom end? (with obv cams, headwork, bigger turbo (s), intercooler etc etc)
On the BIG power engines- 600/700+bhp examples, what compression ratio do they run?
And also, does anybody use an aftermarket stand alone engine managment, like a MOTEC system etc, as i only ever see people running F-CON V and APEXi setups etc where u still have the airflow meters in use, and id of thought (as on most cars), the airflow meters are a restriction if anything.
Also, is there anywhere where i can read a DETAILED tech spec on the 2mental Abbey Skylines at T.O.T.B?
I was most impressed by the way the Skylines launched, none of the other 4wd cars (and obv not the RWDs) was anywhere near as fast off the mark, even if a car was as fast once rolling, a skyline would be about a mile ahead due the the incredible ATESSA system!
My current car is completley stripped and 420bhp so id say its 400bhp per tonne at least, so id want same/more bhp/ton in a skyline, which isnt so easy as they weigh, well, lots, so as much help as people can give me, ill be happy to have.
Thanks in advance for all my questions, but i need them answered as i MUST have a big power skyline, the 2 Abbey Skylines have completley changed my opinions on cars- 420bhp and RWD is not enough for me now...
Cheers, Steve
