Aren't the ke70 strut tops a different bolt pattern, did you have to change the lower arm too? Or did they bolt straight in?

Just a quick question... what discs and calipers can I fit to my ke30 as an easy upgrade as the standard discs are tiny! and with the new 5k the will be a little small. I don't want to change struts and have heard early Celica or Corona discs will fit straight on. Has anyone done a conversion in their ke30/55 and can recommend an easy upgrade? Cheers

Measured with calipers and they are exactly the same, both fill with oil via holes, so both hydraulic. It's just the internal you can see are different, one has a spring type design the other is an oil filled piston type. I wonder which is better or newer?

All from 5k's

Hi all, in the middle if the 5k build at the moment and I have three different types of lifters. Does anyone know the difference between these two? Which is better? New version? Any ideas which I should use? They are the same overall dimensions but obviously the internals are different.

True that, go the K series! Do you think 10.7:1 with a 261deg .417 lift cam, flows and twin carbs will work ok on 98ron? Or is it going to ping like crazy?

oh yeah, 1.0mm over size bore. So his will fit.

Yeah I have been chatting to him, what brand are those ones? hes away till thu and thinks they are Hypatec but then with the cheap price I found online for the Hypatec $105 he thinks they may be Endurotec

I'm a little confused about which piston to buy. I am looking at the Hypatec and the Endurotec for my 5K. From what the company website says the Hypatec sound better quality, but they are cheaper than the Endurotecs? Has anyone used either of these, or know which is better quality? I can't get into the shop to have a look at them side by side to compare. Hypatec® is a high quality performance piston. Hypatec® pistons are all manufactured from 11-13% silicon alloy combined with T6 heat treatment to create a piston that is stronger than many other pistons. Plus, every Hypatec® piston is manufactured utilising state of the art CAD/CNC diamond tipped machinery. The end result being a piston that can withstand the severe loads associated with today’s performance engines. High silicon alloy is the preferred material for most cast pistons because it provides greater strength and greater scuff and seizure resistance. The silicon acts as small insulators, repelling the heat created in the combustion chamber, allowing the combustion chamber to retain its heat, creating a more efficient combustion process while the piston actually runs cooler. Hypatec® pistons are heat treated using the T6 heat treatment process. This is a specialist process which is performed in two stages. During the first stage the piston is heated to 500°C for 9 hours and then water quenched to create a single phase alloy. The second stage involves heating the piston to 180°C for 10 hours and then allowing it to air cool. As a result, the alloy hardens to form a copper aluminium crystal, CuAI2. It is the formation of these crystals that give the alloy its strength. Hypatec® pistons are manufactured by original equipment piston manufacturers. Because Hypatec® pistons are developed directly from the needs of engine manufacturers, the latest design features are used in many Hypatec® pistons. These developments include; anodizing, alfin inserts, ceramic fibre squeeze casting and gallery cooling. They are all original equipment developments and are included in the Hypatec® piston range for the aftermarket. Endurotec® pistons are sourced from various world class suppliers. Make no mistake, these pistons are not seconds or factory rejects and are all manufactured from quality eutectic alloys with T5 heat treatment that are basically the same as many other premium brands. Every Endurotec® piston set comes complete with comprehensive fitting instructions including piston to bore clearances and are presented in dynamic Endurotec® livery.

Thanks for the thoughts guys, I think I will get it balanced. I think I would regret if in the end if I don't. On another note Hypatec or Endurotec pistons? from what Precisions website says the Hypatec sound better but they are cheaper? I was talking to another guy who is selling some on Rolla club and he also said Hypatec are better. Seems a little starnge at half the price of Endurotec? Anyone seen these side buy side? which is better quality?

You getting any detonation with that comp ratio? sounds way high?

Free air delivery

They go for $399 when on sale

190L/min, 2.5hp, belt drive, twin cylinder, 50l tank, 24month warranty.

How much did that cost you?

Yup, cheers. All good info, Definately going to do it once and do it right. Those little one just won't cut it. Cheers for all the info, I recon I will wait for the Stanley $699 model to go on sale, hopefully before christmas. Seems to have pretty good reviews and suitable specs for my needs. Thanks again

Hi all, was going to start building my 5K this arvo as all the new bits have now arrived, but I'm still not sure if I should have the crank, flywheel balanced. I'm going to balance the pistons and rods myself more for experience and to have a bit of a play rather than performance. This is not going to be a race engine, 7000rpm max. No track days or anything just a weekend car. From what I can work out, yes there are benefits to balancing, smoother at higher revs, very slight engine power increase, longer life of engine. Still not sure if I should bother with bottom end balancing? K series are supposed to be pretty good from factory. Any ideas? Cheers

Yeah, I've found a few around $450-700 I think buying one that will last is a good idea. What brand is yours? SP air look ok, Scorpion? Spears and Jackson at bunnings $495 200lpm 2.5hp belt drive

Have you seen this? http://www.ebay.com.au/itm/V8-LSD-DIFF-Complete-Drum-axle-centre-custom-Drift-drag-project-ke30-ke55-ke70-/171177340027?pt=AU_Car_Parts_Accessories&hash=item27daf6ec7b

I'm guessing most if not all of you have an air compressor of some sort in the garage for either the odd job or all the time. Can anyone recommend a brand or size that works well for them. I need one thats going to allow me to do some painting now and then, DA sanding of panels, some grinding and use smaller tools too. I see super cheap have a special on their 2.5hp, 120lpm, 40ltr tank Blackridge compressor, would this cut it for the tools I want to use? I'm guessing probably not but not sure as I havent bought a compressor before. Any advise would be appreciated. Cheers

they wouldn't last long! haha Done, big socket+little socket+hammer+gentle massage.

does anyone have any tips for removing and refitting small end bushes. Will they tap out with a punch? or do you need a hydraulic press? havent done this before so any advice would be appreciated. Cheers.

Yeah, its not an extreme engine just something drivable for sunday cruises, and I want to keep it looking factory as possible with the carbs and air filter. I will get it on the dyno once its all done, and we shall see!

So I'm rebuilding my 5k, 40over, wade 169 cam, double valve springs, 10.5:1 comp ratio, factory twin sprinter carbs, a little bit of porting and combustion chamber clean up, some bottom end balancing, flows and 2inch exhaust So what are your estimates for hp? just for discussion, might be interesting topic. What are you guys getting from your K series engines? I think i might get 100+ maybe 110?

Cheers mate, yeah I think i will just go ahead and do the swap. Its not a massive mod and bolts staright in so I reckon I should be ok.
