I have a R31 skyline with a RB30E NA, and that thing pisses on SR20DE manuals.. And i dont have much mods on it, just exhaust, pod, timing etc.. I know its a skyline forum, but i would go with the silvia if the car was going to be NA. Better power/weight, a bit sluggish as well, but not as sluggish as a 1500kg NA 2.5L :D

im not at all biased, my mait easily has one of the nicest looking silvia's ive every seen, it will out corner my car neday. but just doesnt have the feel of my car on the road. It is also the NA CA18DE and well lets just say its a joke.

ok cross my heart...

Cold morning...

@ 3 lane hwy...

@ light; goes Green

we took off

Silvia was faster at the take off about a 1/3 length...

then as soon as I hit 3k rpm and over in 2nd and I was pulling infront of him, just saw him pass my right hand view mirro...

there was two people in the car in skyline, there was only driver in silvia....

we both backed off at 4th gear 4000rpm... :(

*this was happen @ private road*

cheers

ya know u ask this question in a silvia forum u'll get a different answer. alot of what is said here is biased and thats no shit. being a fan of both silvias/skylines i think the sr20de is rather good and would go alright. as for people saying they piss over ca18det's in rb25de's well then i think someones pulling their chains. cause a good driver of a turbo ca is not slow thats for sure

mm definately go na rb over na sr (105kW & 178Nm or 117kW for s14 sr20) or ca (100kW & 159Nm) (cough laugh)

power isnt the only figure to quote here guys, you gotta think torque aswell - the rb 25 shits all over either of the 4 cylinders just cos its got the extra 2 cylinders - 142kw and 231Nm of torque means it is not a slow car -sure not as fast as the turbo- u'll get a manual under 7 sec with mods - and whoever is quoting 1500kg for a 33 i think is a bit off - i'm sure mine doesnt weigh anything like that - otherwise i wouldnt be able to whoop vs commodores with a totally stock car (not nemore tho) which weigh in at 1430kg would i?

u also gotta consider longevity - the rb 6 is gonna rev for longer than a ca 4 and probably as long as an sr (before i get pm's telling me the sr is 'bulletproof') not too mention value holding - as soon as the 15yr '89 model silvias come over next year cya lata silvia values

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
