see how the EF-block . 72mm EJ Piston in action. Running 5th Gear

Spec-
660 Block
EJ 72mm STD Size Piston, + Skimmed 1mm Top
Stock Turbine 0.8 Bar
Stock ECU
No Fuel Regulator
Mivec Injectors

lag maybe due to uncontroller AFR.

last week my engine head crack due to overheat, change to NA 12v head + 2 Speed radiator Fan, today set to 1.2 Boost
the overheat problem is still the same, the engine temperature increasing very fast when using aircond or when the turbo always on, do you facing this
problem detomaso? or any suggestion from expert here sweat.gif

l5...performance just nice...fc is way better than l2...digital boost controller will cost ya around rm 500-2k...

but L5 spare part is kinda pricey too.

For the sake of L2 spare parts compatible with Perodua..

Is it better to go L2s Turbo halfcut or L500 Turbo 3 cylinder halfcut?

Is it possible to get L2s halfcut then use L5 dashboard?

which is cheaper to maintain?

lastly i got the solution oledy sweat.gif , the problem comes from my SQV BOV, my BOV rosak and the hot air leak out from the BOV and blow the radiator with the hot air instead go to intercooler doh.gif

after change to new SQV the temprature around 2 or 3 dot

but when blast2 using aircond the temp going up to 55%, but still maintain, may be due to high boost

0.8.... see the vid.. i go pull 5th gear.. temp remain the same..

pull 5th gear means longer time to take compare pull 4th gear.

L5 spareparts is more hard to find. As I was told by those mech. L2/L2s may use kancil parts but not L5. BOV really helps on reducing engine temp? As I haven't got the bonnet with scoops.

Get your facts straight, increase cc wouldn't always increase torque, yes, most of the time it would, but it will depend on the design of the engine itself, in the case of the Mira EF series engine, the bore is bigger than the length of the stroke, so the bigger you increase the bore, the higher the powerband will become, which is the same case as F1 engines which have bores bigger than the length of the stroke thus their powerband is on the top most of the rev range.

That is why I mentioned the 850cc ED series would be a better choice to be rebored and fitted with bigger pistons as it's stroke is very long at a length of 81.0mm(compared to the original bore of 66.6mm, bigger bores from Daihatus EF 68.0mm, Mitsubishi 4G13 71.0mm, Daihatsu EJ, which is from kenari/kelisa 72.0mm and if not mistaken, Toyota 2E 73.0mm), all of these, it will never reach the stroke length of 81mm, even if u take a 81mm piston, I doubt there's enough space on the deck for such massive overbore.

This is where most people don't get it for hybrid engines, You don't even need to rev that hard to make more power anymore, same issues and arguments going on all along wif the B20B, the K24A, the 7A-"G"E, and various other hybrid stroker kits. Most just don't get it that they no longer need to rev as much to get to the peak of the power band(which is actually a good thing, as torque builds up from much lower revs and thus, better drivability).

Believe it or not, but any properly done up(as in installed properly, with the right parts, not like "properly done up" as in going all crazy with one-off bits and pieces) 850cc with only 68mm Daihatsu EF turbo pistons(basically built up like any Daihatsu EF except using the 850cc ED block wif the matching 68mm pistons) would beat the heck out of any 660cc block running even the biggest piston you can fit, on the street, or on the track. You never find those guys running 660 overbored blocks to have problems with the clutch burning out due to the massive torque but there's always people with 850cc simple hybrids having that problem.

Well... I guess I better STFU then, guess that's what happens to most of the know-hows in the forum, they always get tired of even trying to explain and juz STFU instead. Maybe you know better, as you probably built a lot of overbored Kancil turbos by yourself before.

Good luck to the TS in his search for power then. thumbup.gif

lol... 660 with oversize pistons cant beat 850T? lol... what a funny guys here... dont just say anything if u already done it bro... wub.gif ... looks like u have post with a lot of kinda infos of various cars here... sure u otai in mods .. maybe u know better...

sorry to say but u re wrong .. totally wrong!!!
nowadays 660 also can match up 1000T, but in a very hard way... whistling.gif
if u go to drag strip, pls count how many cars use 850?? i wonder you can keep your other hand in pocket to count it!!
lol...


hmmm, even thou this is old thread, but i want to put it right... u were wrong!! icon_rolleyes.gif


dont just easily put all things on engine... dont forget we have gearbox!
