  1. What's your obsession with heavy duty valve springs? My standard ones would handle decent revs. Why put extra load on the valve train when it is not required?
  2. Oil catch can. Used to stop oil fumes from the motor being sucked into the intake.
  3. List of things to do to convert your KE20 to 5K power. - Pull 3K from engine bay - swap your manifolds, accessories, bolt ons etc from the 3k to the 5k to keep things simple. - drop 5k in the hole that the 3k came out of. Depending on the year of your gearbox, one of the bolt holes may not line perfectly up but use of a drill will solve that. Easy conversion. Anyone with a little mechanical knowledge should be able to do it in a day. Drop in in and enjoy the torque that 1.5l gives you :)
  4. I've already answered this twice, but yes....... As long as the extractors you have are for a KE70
  5. Check the tail shaft bolt spacing on the diff flange, there may be a difference. Try to get the tail shaft for the Borg warner diff as well to eliminate any issues.
  6. Shot peening is usually done to increase fatigue life of components. The compressed outer layer helps prevent fatigue cracks from forming if I remember my metallurgy course correctly :) For your extractors, try Jet Hot Coatings in Castlemaine, www.jet-hot.com.au As for the rocker cover, timing cover etc, they are alloy and with a bit (well a lot) of elbow grease and a decent metal polish they will come up a treat.
  7. Any K series extractors for a KE70 will fit. KE10/20/30's have slightly different bodies so may need mods to fit around steering/body parts. OK, going to try and dig into the memory banks on my 5k set ups. These definitely were not wild motors so don't be disapointed. 5k number 1. Vehicle KE35 daily driver. Jap import 5K. 3k-b manifold, air cleaner and linkages. Ran standard 3k carbies (x2) as they had bigger venturies/jets than the proper 3k-b ones 4 into 1 extractors with 2 inch exhaust. electric fuel pump and cooling fan. No engine driven fan. 5k electronic dizzie set to 15 deg btdc initial advance. Pulled engine due to a noise (all the symptoms of a cracked piston, noise even disappeared when plug lead removed). Found nothing. Got an engine builder to check it out, and took the opportunity to shave head. Made it into a different engine. Wished I had of fitted a cam as well to this one at the time..... Great motor, lots of torque. Towed a camper with this car, did it with ease. Brakes were another story though...... 5k number 2. Vehicle KE20 club car. second hand 5k cost $100 bolted into car, sounded great until warmed up when it developed a knock. Pulled out and fitted new bearings. Ran 3k-b manifold set up again modded carbs and aftermarket air cleaners. electric fuel pump and fans again 4 into 1 extractors and 2" exhaust again. Fitted the Wade 169 grind when doing bearings. Closed eyes when looking at everything else - called them racing clearances :) This was basically it. Standard head, etc. People would not believe me at meetings that this was all that was done to that motor. It was still enough to knock 3 to 4 seconds off the time it took to do a run on the Ballarat Autocross track when compared to the original 3k. Lots of fun for a car that cost me sweet ^%^^ all to build, probably less than $600 including the cost of the car. Always had plans to do a stage 2 motor. Do the head, up the compression, bend the diff to get a little camber and toe in but kids came along.......
  8. Yeah, got old real quick. Ended up mounted on rubber isolators bolted to the spare wheel well. Took a couple of goes to get it quiet enough to live with. Did try a Holley red pump under the bonnet but removed it as it wouldnt self prime. Got sick of sucking fuel through the line to the pump.
  9. When running factory twins, I felt it had a better top end after I fitted an electric pump. But it was a noisey little bastard pump though...... not helped by mounting it under the rear parcel shelf.
  10. Honestly can not tell you. That motor was built back in the '90s sometime. Handed the head and block to a local engine builder and told them to up the compression as high as we could run on pump fuel at the time. When we reassembled it, stock rockers, pushrods and lifters went back in. This motor was a Japanese import motor and was a factory flat top piston motor.
  11. Honestly, the Wade cam was nice and drivable with good pull from down low. We also had a 4k with a big cam that was almost undrivable. Would spin you around once you hit 3600rpm in a corner. The 5k was also quicker over the eight mile....
  12. The 5k we upped the comp on was a flat topped piston motor, so a head shave. Shift light would of been on at times in those vids, so at least 7500rpm ;)
  13. I'll try again. Ran a Wade 169 grind. Lift was 0.269" Ex opened 75 deg closed 36 deg Inlet opened 41 deg closed 70 deg. Lift at TDC number 1 inlet follower 0.055" Used standard 5k valve springs. An earlier 5k ran a standard cam, but with the comp raised.lots of torque from that motor. Could go up hills one gear higher than before. There are some YouTube videos of the ke20 in action if you search my username. Any KE70 k motor extractors will bolt up to the 5k
  14. I call bullshit on this As someone who ran a 5k'd KE20 motorkhana car for years, there is no reason to convert to solids. Hydros easily copped with over 7500 rpm, even went off the tacho at times 8000+ rpm. My combo consisted of a reground cam - a Wade 163 grind from memory, a factory twin carb manifold with modded carbs, extractors and a home made exhaust (2" system that went under the diff), and electric fan and fuel pump. Pretty basic stuff but enough to be within 1.5 sec/km to an STI spec WRX on a dirt autocross...... and seconds ahead of a 4age powered KE35 on the same track.
  15. Love the chrome bonnet vents. Reminds me of my first car :)
  16. Did the tacho instead of the clock thing in my KE35. Even went to the trouble of painting the needle the same fluro orange as the standard gauges
  17. We used to a thin smear of gasket goo on both sides of that plate (or plates with the twins) to eliminate any small leaks
  18. mums metal coat hangers made great welding rods while making exhausts for the motorkhana car ;)
  19. Your braver than me. Messin with the missus's stuff.......... :rant:
  20. Ke35 with twin 3k carbs (not 3kb carbs) on a 5k would run around the 9-10 l/100km high cruising depending on fuel quality. Would empty a quarter of a tank real quick at 160 km/h though (under controlled conditions of course...... ;) )
  21. Or track down a 5K and enjoy the torque :)
