kpr's kp60

edit: thankyou new page

since no one wants to play this little game.. seems i was a liar when i said 8.5's wont fit on the back

so i kinda fixed mexi on the front, and lowered it a little more. sounds easy, but i had to cut the adjustable platforms off and re-weld them down lower. as it was maxed out. also, it only looks like this on one side, so far

[kpr]

So, i managed to get this drive-able with the 03's all round. rubs a little up front.  but good enough for the track.  Exhaust is almost due for rebuild again, since losing half of it in sparks. light weight version is on the list.

edit: thank you Seedy Al for the streets.  I also hate you for selling me a pair

Took this down to mackaz this morning. chucked it on the wheel alignment machine, to get some numbers.  didn't adjust anything other than front toe.  

toe on the rear confirms what is going on with the diff. left side has always sat further forward in the wheel arch.  chassis or diff link issue by the looks. as everything on the diff itself  measures up good. not sure how i'm going to go about fixing it yet. but should work out good once its sitting straight, looking at the total toe number.    camber is close to spot on. not bad for a square and tape measure!

 

front needs a few adjustments, but have some good caster numbers over stock.

quick vid from today

 

 

[kpr]

Few more vids brother took.  i was having trouble getting over the hill !

 

 

^At the end,  was the end. diff broke.  thought it was one of the welded axles. but pulled it apart tonight  and has broke the right side gear/spline. (not sure what you call it)  in the lsd. guessing it didn't like the camber or possibly because the axles weren't engaged as far as they were last time.  or just the raw 4age power

[kpr]

cheers to all these dudes, for the sweet pics

Everyone likes some destruction.   There is meant to be 2 parts in this picture not 4.  Not 100% sold  that the camber mod is responsible for the broken bits.  if the axles were engaged into the side gear another 5-10mm it wouldn't have broken.  unsure if the shaft has broken at the same time. almost looks like it has been broken for awhile, but hard to say. actually i dont know what to say when hilux diff breaks, behind 4age- cheap shit clutch and t50 box.

Boring update.

Got new lsd. trd G code irs center.  done the small mod required to fit it in the live diff carrier.  same center as i run in the trueno, some pics here of the adjuster mod

 

//oldschool.co.nz/index.php?/topic/24594-kprs-ae85/page-2#entry677656

 

the whole diff  center ends up offset to the drivers side, its not just the crown wheel flange that is offset.   kinda worked out ok, as the right axle ended up the correct length.  left was too short, but again managed to grind welds off and press axle apart to lengthen. better than having to lengthen both sides!

 

seems i also broke the gearbox on  the same lap.  doesn't downshift  into 3rd anymore.  sadface

 

found  this pic on brothers camera,  do a skid bro

 

[kpr]

Another boring update.   But you can feel my pain by reading this text.

 

The final list of broken stuff from hampton downs:

 

LSD - as above

Gearbox - replaced selector hub/sleeve. seems these are made of cheese as the brass synro ring itself was fine!

Clutch -  checked this when engine/box was out,  center of the friction plate was a few clutch kicks away from flying to bits, cracks and bits missing- cheers to my mate rangi i had a replacement within 20 mins!

Throttle linkage- yeh that was broken too.

 

Everything had taken a good beating over the years, just happened to let go at the same time, i hope. Seems you just can't stop the torque of a good 4age. no really...

 

Anyway its all working again, ready for some more beating. Another day at hampton on the 6th, unsure if i will go yet. was going to make some more changes first.

[kpr]

making new ali exhaust. isn't pretty and stink phone pics. but thats not the point

 

its 2"  tube with 45mm (was spose to be 50mm but had a mare) flat welded down the center.  which works out around 3" ish.

 

 

rather than making  mufflers/reso's then welding it in place. i made the whole system then are putting reso's where they will fit. drilling all these holes was extremely boring.

 

 

outside of muffler started. 

 

 

reused the slip joint  that was on the rear muffler.  to change from stainless to ali.  this is thick wall. 

 

[kpr]

This aluminum exhaust isn't going to plan.   sounds ok out the back, but is raspy and noisy as a shit in the car.  Its pretty much the same as the stainless system, muffler and design wise.  Seems most of the noise is coming from the section between the extractors and first muffler. some kind of harmonics going on.  At  the moment i've chopped it off just before the first muffler.  Will put the old stainless section back in here tomorrow. so the first ali part will be straight into a muffler.   If this doesn't work the whole lot is going on the wall of shame.

 

More of the broken stuff. cheap clutch.  served much abuse. happy i checked this before it flew to bits! can see the cracks and missing bits if you look closely

 

 

Oh and  chucked the fins on one side, to see what it looks like. 

 

 

[kpr]

Changed  front section back to stainless as above, and its fixed!    Still a little loud and bit of a drone in car.  but raspy vibration is gone.   Once last last muffler finished (ran out of fiberglass). should hopefully cut out the rest of the noise, back to how it was before.

 

Looks pretty shit, got cut up so many times i gave up caring.   if you are looking under there i fell sorry for you.   Have also gained some ground clearance. along with some weight loss

 

 

i really need to kill those weeds.

[kpr]

The silly aluminum muffler ended my day early yesterday.  lasted till half way through the 2nd session, then collapsed halving my wrath of power.  open headers was insanely loud, so didn't bother going back out, to get kicked off in the first lap. 

 

brother did get a few vids before it broke.

 

[kpr]

first up, got some fancy  180sx raybrig headlights.

 

 

 

seems to be a slight problem with the muffler, (excuse the poo poo welds, i have my reasons)

 

 

lets chop it off see whats going on

 

seems to be a slight blockage, hmm cut some more

 

that doesn't look too good ^.   oh shit

 

the rest of it seems to have disappeared.  its either stuck in the rear muffler. or stuck in some poor bastards face at hampton downs

shortly after this i had to go to a&e and get a few stitches, this aluminum exhaust hates me. 

 

 

 

 

[kpr]

Soon i will find the sweet spot to change  to ali.  This is the latest.  Sounds a little bit stink again, since first muffler is smaller. If i ever finish that mid muffler, should be ok.

Also jammed in a cusco gearbox mount in, to replace the sloppy 30 year old ae86 one.

 

 

[kpr]

pretty much taking the piss now.  

 

no actually i did cut it up again.  harmonic vibration is the bland of my life.    finished  the rest of the mid muffler.  still had the buzz in car.  the first reso wasn't taking enough out, so the ali section after was getting its buzz on.   turns out i could squeeze 3" round from here back.   so latest version:

 

 

yes, it has all the metal's  now.  stainless -> mild -> aluminum   

 

 

no more bizzz,   but  im sure this isnt over yet.

not bad for stock cams and going through a hilux diff.   ballpark blacktop 20v 4age power, which is what i was after.   rpm on graph is a little off,  revs a bit more.

 

ingredients:

 

diy ported small port head

weak factory small port cams

blacktop throttles

extractors

roughly 12.5 -13   compression

whangarei magic

 

[kpr]

overlayed on the old big cam setup,  red lines that go off the chart, are current as above.  (old engine would not work below 3500rpm at full throttle)  20kw more at 3500rpm.  15kw less at peak.  more interestingly  peak power is about in the same place, and seems to hang on just as long.   aim is to try hang onto most of that 20kw down low a and match the 105kw peak.

 

 

[kpr]

New stuff.  Cams  from Rob!        Wheels arrived from japan also. brought these about 2 weeks after selling the old ones.   they are a bit more aggressive.  14x6.5 +4  and 14x7 -2,  ideally i want to match the 7's up with another pair 7-8" wide. 

 

 

way less aggressive than what i was running on old setup,   but will hopefully fatten it up a bit.

n/a geek cam post:

 

Got these cams in on Sunday.   Had to reshim the whole thing, as the valve clearances were  all well over  0.3mm. (should be 0.2mm inlet and .25 exhaust). Wasn't due to the cams though, was the same deal on the factory cams.  which i had suspected anyway due to the sweet rattles when cold.   Dialed the cam timing, to the recommended settings on the card.  well no i didn't, was spot on using factory marks!   would have been straight drop in if the valve clearances were right to start with. 

 

robbed the toda cam gears back off the truneo, and threw on toda cam belt i scored for 35 dollars, off trademe

 

just finished running in the cams, then done a couple of full power runs up the road. first dialed 15-20% more fuel into the map from 5000rpm onwards, to make sure its on the rich side.  feels pretty lazy down low, but wants to keep pulling hard past 8700 limiter.  more so than the old setup with 300deg cams!  and.. still starts to go a little lean right up top with near 20% more fuel. which is good  news.  yes it also sounds 20% more awesome.   will likely play with  cam timing to pull the power back down in the rpm a bit, but will wait till have a decent tune on it first.   would be sweet to dort around over 9000rpm. but my setup is a bit peasant spec for that
