Maybe... does your turbo overboost during the vacuum issue?
New turbo never cheap... I've ask for a new RHF3 for my L5 engine and got a rm2xxx.xx!!! might as well get a new halfcut instead....
Not sure about L2 stock turbo (RHB series rite?) but normally my L2 frens will get a RHF series from L5/L6 3 piston engines... highest I saw for a halfcut unit was RM4xx...
to service a stock turbo might be expensive.... for my RHF3, I got around rm6xx service quote.. might as well get a hybrid turbo (RHF3 turbine housing + RHF4 turbo)... more power and it only add another rm1xx or so...
My advice to you is
- If going for the halfcut route, better go for RHF3 from 3piston L5/L6 (the cheapest)
- If going for recond route while maintaining relatively easy installation, get a hybrid turbo.... I think @ Tong Turbo you can get a hybrid turbo for L2s series; or
- Custom mod another similar turbo from other brand... TD025 from eterna twin turbo is a good bet, but you might wanna mod the exhaust manifold a bit.. or
- Go big! there's always TD04-09B + front mount intercooler hehe
normal la bro playing wif hafkat... last 2 week when my turbo broke, got it replace with L6 ones, all tested ok, no shaft play etc... but barely a week later white smoke again, already spent rm400 for that turbo
...now saving for RHF3 + RHF4 hybrid...
My Turbo Over boost during the vacuum issue? I’m not sure sir, I think maybe..
Because when I had the vacuum issue, even 0 bar it makes lots of 'kccingg' sound.
I think even it showing 0 bar, but actually its not 0 bar, maybe higher.. And I sometimes push to 0.7 bar (even when having vacuum issue).
I’m not sure of L2 stock turbo on what series are they, how to check?
Can I go the same option as you? choosing for RHF3 and RHF4 hybrid?
Please advice as i'm newbie on turbo :) really appreciate
