  1. bumpers. still rolling the 2k? or had the 4k upgrade?
  2. have done a half assed tune with the new cams. waiting on bigger injectors as current ones are maxed. but seems to go pretty decent. is gutless till about 5500. then comes on strong and power is on the rise, all the way to the limiter. (8300 at the moment) with a fresh block, more compression and a few other tricks. should go pretty sweet. sold the forged internals for my fwd starlet. and brought these for the 4a instead: 1mm oversize bringing it out to a massive 1627cc. 11.3:1 compression ratio with stock gasket. should be near 12:1 with trd head gasket have a silvertop block getting built at the moment, with the above pistons. arp rod bolts and balance. so should be good for some more revs without flying apart. will give head a tidy up when its swaped onto new block.
  3. got some new cams, tuning it at the moment
  4. might look into an air box setup at some stage. the filter will do for now though, can allways remove when racing ect.. if its loosing power havent had the car on dyno. but going by where ive added and removed fuel from the map. seems close to what the calculations were. im using a smaller collector outlet than what that site suggests. was something about the firing order of v8's witch required a bigger collector. than evenly spaced firing order of 4 cylinders.
  5. for the mounting points. in general, if you lower the lower arm mounting point on the diff. you should gain some traction. but will increase roll steer, witch will make the ass end loose and sloppy. ha. top link will have similar effect.
  6. been trying to make this air filter fit. remote mounted brake and clutch reso. moved engine to the passenger side 15mm. kinda have enough room now. new trumpets. 2 more to go.
  7. at the moment im running 275lb in the front, and 250lb in the rear. i wouldnt go too soft in the rear if your going low. else you'l run into issues with it boucing off the bump stops. i had that problem up intill i put the 250lb springs in the rear. before that i was running a progressive rate spring (think it was rated at 200lb) that was out of my other car. didnt quite feel right and would do as above. going to the 250lb springs it didnt seem to loose any traction. harder rear springs will compensate for the lack of rear sway bar also. so with a rear swaybar. possibly go a little softer. would go 200lb at least with 250lb fronts.
  8. having the springs closer to the outside of the car would be another advantage
  9. turreting the rear is actually real easy. i was surprised how well mine went. i just used some 4" exhaust tube. drilled the top out of the standard towers with a 100mm holesaw. lined it all up and welded. only tricky bit was the tophat part. only because i made up my own spherical bearing setup, so had to do a bit of machining. although you could just use something off the shelf or a standard tophat off something. depends how far you want to go really i guess. in my first comment, was more meaning get some decent shocks and springs to start with, even if you dont turret the rear. the usual short stroke kybs probably wont be good enough to handle the spring rates you'l want to run at the track. saves buying shit twice. as for the stock rear binding up. if you release the tension on the bushes. it doesnt bind at all. just need to loosen and retighten the link bolts when the car is on the ground, at its new lowness. but yeh in saying that, i'd love to change mine from the trangulated setup, to a proper 4 link setup with watts or panhard.
  10. i say go with a mean suspension setup first time. done mine about 3 times before i was semi happy with it. have a rusting kp here if you need bits off it.(doesn't have much worth taking though) can send you the rubber brake lines. but dunno about the metal line if you need that. plus i dont wanna crawl in the mud
  11. have to agree with this. when the kp was 4X100 i had stacks of burnout tyres, but lots of gay rims.
  12. almost done. just need to attach to exhaust. trying to decided if i want to try a megaphone setup or not first.. fuck my ears hurt anyway. complies with current exhaust laws
  13. keen for trackday. rarity, i only got a t series one.
  14. just out of interest. can you adjust the ignition curve at all? or is it fixed to what they have programed ?
  15. shit, i just have too much time on my hands i think aye. ^ you have the mean base to start with. your p&p looks far better than mine. FLAWLES you cunt, love the epic widebody race style. i have some bluetop cams here, if you were looking for some for your smallport. cruising at puke was doing some try hard d1's onto the back straight on other laps. think i was going slow, because someone spun.
  16. finally 4 pipes the same length that fit! looks like some fool has tied my headers in a knot
  17. at the moment its got a fat lazy power band ( or lack of it). trying to move the power up the rev range a bit. aiming for around 7k with the extractors. used this site a bit: http://headerdesign.com/ along what what ever else i could find. the straight part before the collector should let me shorten, or lengthen them fairly easy. if they dont do what i want. on the intake side, i pretty much tried all different lengths and hoped for the best. will play with the intake side some more once the extractors are finished. mean, thanks for the comments,
  18. ripped them apart countless times. almost there now still sussing out no# 4, will be a bit diffrent than in the pic. as its too close to cas. plus run out of bends.

    yeh i've always liked the blended into a flat plate method best. the turbo inlet manifolds ive built have always done it that way. maybe slightly off topic. but, if your going to be messing around with different trumpets at all. don't just try a few different lengths and go with what feels best. need to retune the afr after every change. makes huge difference to tune. tried some shorter and different shape trumpets on the kp the other day, this happened to afr: http://www.starletcentral.co.nz/images/kris/afr1.JPG use to be flat 12.8'ish afr

    where do you guys get your heat wrap from. i've used a few different types, and been pretty disappointed in how long it lasts for the price, one lot kinda rotted and fell apart. another went hard and shattered like glass. haven't noticed any corrosion tho, heat painted extractors before i wrapped them, seem all good hpc gets my vote too

    in the combustion chambers, id remove any pointy bits. deshield the valves if required/ possible, but try not to cut out the squish areas. ports. tidy them up. check for bumps behind the valves where seats have been machined, 4ages have some nasty ones there. in the exhaust ports, you can possibly sharpen the divider into a point, were the gasses from each valve merge. match to manifolds etc. wouldn't bother fucking with it too much more than that unless you find someone that really knows there shit about that particular head. inlet runners. the usual bell mouths, large radius will be better. rolled full 180 degrees, or 90" blended into a flat plate seems to be a good argument.... taper is all good. doesnt need to be much 1-2 degrees. no one likes to give out secrets on this, so do some shit and hope for the best.
