Mod for mod a silvia/180 will always be quicker if driven properly. people often underestimate how good the SR20's are. They are one of the best performance 4 cylinder engines ever produced. 12 years after they started production and there is still nothing around that is close to its popularity or performance, other than the S15 which has now been discontinued anyhow.

Just remember that because you might have 240rwkw and you race a 180/silvia with say 205rwkw, the silvia will win, mainly due to power to weight... yes a skyline will real in top end for sure due to the 6 cylinders and extra displacement but for street driving the silvia will be much quicker.

Do an RB20 conversion on your 180! Ive raced a cat back 180 with sr and beat it by around 3 car lenghts from 50-90kmh... The only mods ive done to it are an RB25 turbo (hardly a mod, just making up for a design fault), FMIC, turbo back exhaust and a slipping clutch! I also raced an R33 with FMIC etc and beat him much to his disgust :O In terms of looks, i have a 93 180 with 18's and it looks not too bad, even with stock bodykit

Before I got the Skyline I considered the 180SX. Even after getting the Skyline I considered selling it and getting an older 180SX ('92 model or so) at half the price just to get rid of some debts.

At half the price it would have been a bargain and given absolutely more performance bang for buck, and if I wanted to be financially sensible that's exactly what I would have done. But performance wasn't what my car is all about, and for the reasons below I decided to buy/keep the Skyline:

(1) I like the shape of the R33 better. It just appeals to me more. Entirely subjective.

(2) The Skyline's interior is better (mm... velour...) Not so subjective (most people would agree), though a lot of 180SX people get around this by upgrading the seats.

(3) I've always liked straight 6's better than 4's. I like the sound better, I like the smoothness.... I dunno, I just like them. Ever since my Torana days. Not keen on V6's (which ruled out the 300ZX)

(4) There's more room in the R33 (well, for the driver and passengers, maybe not in the boot).

(5) Climate control (again I hear some people get around this by fitting S15 climate control. I think?!)

The clinching factor though, is:

(6) My motorcycle will entirely hose almost any Skyline or 180SX you care to mention.

There are some exceptions to number (6) above of course, that pretty much being any car breaking into the 9's or 10's, or capable of better than 1:38 around Eastern Creek (I can't do that time but I know someone who has done a 1:38 on the same model of bike) but they are very few and far between. And there's no way I could ever afford a 10 second car anyway even if I sold the bike and used the money to upgrade a Skyline or 180SX, so I decided to go for the "nicer" car rather than the faster one.

I still like the 180SX a lot, and 200SX only slightly less, and I'd have no problems owning one. But I still prefer the R33, partly because my bike compensates me for my need for speed, but mostly because I just think it's a nicer car.

part a) ....it all depends on the car though really, and the driver, but mod for mod, the Silvia is faster, mainly because of its weight.

Just on power to weight...A silvia (1100-1200kg) with some 130-140rwkw (0.12kw/kg), should be an even match for an R33 GTS-T (1400kg) with some 175rwkw (0.125kw/kg). Both are achieved through similar mods...FMIC, S-AFC (or remap), 12psi or so of boost, and full exhaust

hehe, yup, I'm in both so i see the arguments going back and forward between the two forums on the same topic ;)

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      forgot to mention that when it does this it does not kill the engine, but I have not kept the pedal down long enough to let it, as I see no reason to beat up on it as its got to be something simple, small and dumb causing this.  And as soon as I let off pedal, the engine returns to its normal super smooth operation and rpms re-stabilize quickly, once below 4k.

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock.

      Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.
