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

    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
