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.

alright .. can i get somethingg straight ?

the guys at the silvia forum say they can beat a R33 GTST with their S13/14/15 180sx with sr20det

the guys at the skylines forum say their R33 GTST can beat S13/14/15 180sx with sr20det ..

i dont mean to be rude or anything, but which is the truth ?

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 ;)

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
