Told you already that some faggots are profiteering from this, though alot lambs willing to get slaughtered because they want to save trouble for gathering parts.

Yes plenty 2.0 NA boosted with 240 ATW, but it's not usable as it can only go straight and slow shifting, the clutch cannot take the heat
4B11 high compression mod can only get close to 170whp, max rev 7.5k, as far as i'd seen. It's really all noise and not much of omph, may be i being pampered by the 260whp 1JZ so i barely feel anything on 170whp NA. LOL
Oh you meant turboed 2.0 4b11 NA like what you're planning. Yeah then sure can.

170whp is just normal, like my Mark X only.

Yeah lol ... once you go turbo you very hard to go back.
Not true... I have been exposed to 1JZ RWD, 4G63T AWD, RB26 AWD... and I'm still in love with B18c, K20 and the 6 flat plane porsche 3.4L NA... my god these engines are awesome. Not necessarily the fastest but the way it runs is just intoxicating.
240whp means around 280-290 at the crank, or over 140hp/ltr! If race engines sure but street K20 can really reach that high meh or just exaggerated dyno numbers?

Some more this is Mitsubishi 4B11, not known for high rev NA power like K20.
250WHP or 300 crank has been done to K20's la. But to be fair it's most of the time no more 2.0.

Oh you thought i wanted to N/A mod the 4B11 to 240 ATW ? I don't think its economically possible and i personally think the car would not be street-able. I just bought a cast iron turbo manifold with T2 flange, build looks very sturdy, so any T2 type turbocharger that i could get ? So far my info is T2 turbocharger may refer to Garrett GT25 o GT28 turbos.

If stroked/bored to 2.4 then still much more feasible cuz 125hp/ltr which is similar to stock F20C in S2000 but if stay 2.0 I think it's too far fetched for street cars.

Hi all,

I picked the Garrett AR60 M24N-1, unplugged from a RB25DET because it has the best condition and quite rust free. The shaft and fin looks pretty intact. I think this turbo is a Garret T28 and capable of max boost 1.2 bar. For my settings, i will run at 0.6 bar to see if any engine trouble. Car will be tuned using RON95 as this is daily driver. I am targeting 200 whp for daily driven. Since i am on budget, i am planning to use KKT Compact 32 for the management < alot BOT owners run on this ECU. What do you guys think ?

Aiya... learn from my mistakes la. Don't go for unknown, unsupported, unverified ecus that no one has heard of or tuned before. I made that mistake with Spitronics and haven't stopped regretting.

If you have "a lot" of owners who run this ECU without problem i hope you are good friends with these owners because I do not agree with this ECU. Incidentally why not spend this money to get your standalone ECU for the BMW-1JZ. that would have a WAY bigger impact than your turbo 4B11. Hell, the BMW gonna be faster too and a nicer drive I'll bet.

It's from Thailand, got one Kelisa YRV turbo with 1 bar boost using this ECU, running on automatic gearbox, personally i seen it. Looks pretty stable if you ask me.

BMW is a different category, its made for leisure driving so with 260 whp, it's plenty good enough. Turbo 4B11 on the other hand, its my daily not-boring ride.

It's like I said - unsupported, unknown, unverified.

If you have a tuner who can tune the KKT inside out then go ahead. However be warned every tuner will say they can..... until they can't. Which was exactly what happened with my Spitronics. 3 tuners and none could even get it done right, when I said "right" i mean running condition, not even being OCD here. All of their tunes were half assed in some way or another.

And then there was the 60 deg ignition timing fiasco from the 1st tuner wtf.

First time I heard this ECU.
GT28 should be suitable for your target output but not sure if 0.6 bar is enough to reach that, seems very low boost.

I heard you. I am also got option for more common Emanage Ultimate, my budget is within RM3K so not able to reach standalone ECU. Will do more research on KKT, few have suggested this to me and recent years they gained popularity in some grass roots motorsports.

Yeah target HP is one thing, another thing is the feel when its on the road afterwards, if the feel is good, slight lower HP i wouldn't mind.

If you're gonna go standalone with 3k, why not look at Links Atom used? A used unit could be about 1k+ then tuning from a tuner might take up the rest of your budget.

I tried looking for it, but couldn't find any for now. I know this ECU is very capable too but new one is headache, cost almost the same as my BOT kit :smokin:, well if anyone got any lobang to one unit let me know. Otherwise, i might try another route which is use Evo X ECU.
