Hi Guys. Ive got a s13 thats going to my weekend car. Mainly used for motorkhanas, hill climbs and a bit of track work. What size semi slicks should i use. Theres a nice deal on kumhos on another popular import site. Ive got about 140rwkw, tein flex suspension, s14 brakes, and its lightly stripped. Ive currently got 17X8 and 17X9 wheels so im thinking 225/40 and 255/40, but is this a bit excessive for my power levels. Should i buy some 32gtr wheels and run 225/40s all round

well there's not such thing really as too much grip for circuit or hill climbs. khana is a bit different though as you may have trouble sliding the car around cones etc with 255 semis and 140rwkw. the idea of some 225 or 235 16s on the 16X8 32 GTR rims is not a bad idea. tyres will be cheaper, should still give you good grip, and you'll be able to rotate them front to rear to extend their life a bit. and 32 GTR rims are nice and strong and not too expensive either.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
