Help with 2 problems please

[Paul D]

Right firstly been to have a drive of my silvia tonight im picking it up tomorrow.

1, when turning the steering lock to lock or at slow speeds i can hear a twang noise from the springs on the front of the car. Its got coilovers fitted but not sure what make etc and they're a hard ride. If WD40 is sprayed on the springs it goes off for a little bit so is it ok to slap grease all over where they sit?

2, when accelerating all the way up the rev range the boost gauge never goes above 0.5. Its had a hks evc fitted but i think it has just been unplugged for the sva. Can the boost level drop with all the other parts left on? If i find the wires and plug it in do you think it will solve it?

Apart from these 2 little niggles the car is amazing, money well spent and well worth the wait:nod:

Apart from being messy, non-abrasive grease won't do any harm

What does it boost on WOT at around 4500 in 5th/6th?

i only had a quick go of it and didn't get up to them speeds i'l find out tomorrow on my way home and post it up.

Is it normal for hard coilovers to make noises when turning its as if the springs are jumping or slipping?

if the evc has ben unpluged its problem gone bak to standard boost which will be at 0.55bar untill u reach about 5.5k revs which will boost about 0.7/0.8bar....try that first then see how it goes...

Peak boost should be lower than 5500rpm. From my experience (and I had over six months of struggling with peak boost issues), its 4500-5000 in 5th/6th.

Your suspension issue, my previous coilovers (Tein HA's) didnt make nosie when turning, i replaced these with Apex Coilovers, the front passengerside has the same thing, when turning lock to lock the spring jumps round and 'clunks', i got on to Apex and they have sent me some new mounts for the top of the spring to seat into, which spins freely when twisted, so should solve the problem.

Mine clunk too. Coilovers generally make noises to remind you they're there

Seems like the aftermarket stuff gives out lots of noises lol...

1) Aftermarket clutch - judders
2) Aftermarket coilovers -clunking
3) Aftermarket exhaust - rumbles
4) Aftermarket LSD - cracking
5) Aftermarket fuel pumps - whirring
6) Aftermarket injectors - ticking
7) Aftermarket hi-cams - rough idle

There is a reason why manufacturers fit the stuff they do... :nod: Mind you, the whining 6MT is quite distinctive, as is the steering wheel and roof lining rattle...

 

[gunner93]

Yep even the rear wheel bearing has this slight whirring noise on mine... not sure if its normal or worn out. :wack:

I like numbers 3, 5, 6 and i guess i'd like 7. The rest you can keep along with the steering wheel

Well i fixed the boost issue now. i was busy doing the pigeon mod today and found a split pipe so now problem solved.

Thanks for the info on the coilovers its a sign of relieve cos i was worried about them. I havent had a chance to grease them yet but will do at the weekend.
