Hey people, haven't been on in a while and want to get back to sorting some stuff out for my silvia. Semester is coming to an end soon (it couldn't come any damn sooner....ugh engineering problems) and I can finally get around to modding. I have in stall a new intercooler from a S15 specR. New and better fuel pump and hopefully a new tune set up done by a friend of mine and some software i need to buy. BUT when i bought the car the previous owner threw in a set of 300zx calipers and told me that it was already running the discs (yet to fully verify). Was just wondering, are there any difficulties with throwing on the 300zx calipers, i only have the front two, will it cause any imbalance or anything like that? (rim clearance should be fine, im on r32 gtr rims). Thanks in advance!
So i took the my s14a for a good drive yesterday (first real test since building it) through the hills and started to get some pretty bad brake fade. Before heading out, i did have some brake issue with the brake pedal needing to be pressed all the way down before engaging the brakes. I had bled the brakes twice before but still felt like it had air in the system? I've checked for leaks and all is good. Rotors also look good, look recently machined. Also when pumping the brakes, you can hear air being pumped like from a bicycle pump, is this a normal sound? Since yesterday the brakes squeal like a b*tch when pulling up, even just daily slow driving once heated up. Trying to figure out how to fix this problem?? Im running: ABS removed BMC44 master cylinder S14 (4 pot) front brakes (drilled rotors) R32 GTR (2 pot) rear brakes (solid rotors) Unknown new pads all round (came with car) Penrite Super Dot 4 brake fluid Also I have been bleeding the brakes from the calipers only thus far, furthest one to closest as usual. But a friend has told me to try bleeding from the master cylinder first so ill give that a try when i get a chance. I've never had to do this way before but is this the right method, bmc first, then calipers as usual?
I'm getting to the point where my S14A is fairly complete and I want to improve some of the existing key parts, it's just going to take some saving between each one. Usage of the car is 1 lap street sprints up to 5 lap circuit sprints. It's still street registered and full weight. I haven't done a while lot of events in the car, upgrades won't be at the cost of seat time. Current mods are listed further down, the 3 next major outlays I'm choosing between are: Coilovers: Upgrade HSD 7/5 coilovers to KW v3 6/4 coilovers. I've chosen these over the Koni/Bilstein options for a few reasons including no binding issues with Z32 uprights, but mainly because I can just order and install vs sourcing parts and assembling konis. Net cost approx $1700. Calipers: Upgrade standard gear to Wilwood Forged Superlites with 310mm 2 piece curved vane rotors. These are quite a bit lighter and replacement rotors/pads are cheap. Will help with temps and fade resistance in longer sprints, not so much the 1 lap sprints. Cost approx $1000. Diff: Swap S15 HLSD 4.08 ratio to 1.5 way 4.3 ratio to improve traction through and out of corners. Approx $700. Current mods: Engine- Currently 230rwkw, needs a tune to get around 250rwkw. Not enough E85 availability here to change over. Cooling is good (typically runs 68-73 degrees), engine is reliable (forged internals, all quality parts and accessories). Wheels/tyres- Nitto NT-01 255/40/17 on Enkei RPF-01 17x9+22. Better semis would be worth a few seconds but I'll upgrade these when the current set are done. Have ordered a tire pyrometer to assist setup. Driveline- S15 HLSD with 4.08 ratio, Exedy clutch, standard tailshaft and flywheel (will upgrade these to lightweight items next time clutch needs replacing) Braking- Standard calipers with A1RM pads and DBA solid face rotors front, TRW pads rear, braided lines, master cylinder stopper, will make some air deflectors Suspension- HSD HR coilover 7/5 springs, Whiteline swaybars, strut bars, all adjustable arms (Neotech & GKtech) except LCAs, have ordered subframe risers, awaiting GKtech knuckle development to correct front roll centre Interior- Bride fixed back bucket seat, Power FC & AVCR for monitoring, have ordered lap timing gear Aero- CWest wing, vented bonnet, will fabricate splitter/undertray/air dams after next event Stolen pic from last event (awaiting originals from photographer)
