sory for brought up dis old thread..i've used this td04-09 before but from different engine..from my digging up in the internet my previous td04-09 is from mitsubishi lancer 1.8 turbodiesel..difference from penagihdadih turbo was my turbine housing only 3cm2(based on code written on the turbo)..mine start spooling around 400rpm earlier than penagihdadih unit..
from there i got this idea off running the biggest td04 i can get my hand on and i got my "new" td04hl-15G from volvo 850..still not the biggest td04 but for me that thing about twice bigger than my previous td04-09..for my 1st experiment i just port my old 3cm2 turbine housing to fit the new turbo and the result is spool time become much2 sooner..in fact almost 1000rpm earliear than before..with this setup i was able to spooling around 2200rpm and reach full boost around 5k rpm..but the output is a bit dissapointing becos with this setup ,my engine only produce 90hp instead off 104hp while i was using that td04-09..but my torque seeing a good 2kg increasement..from 11kg to a 13kg..this was achieve with the same boost level around 1.2-1.3 bar of boost..
this setup seem the best setup for city driving but i sacrifice too much when driving on hiway..so for my next project i was thinking to upsize my turbine housing from 3cm2 to 5cm2 from mitsubishi 1.8 gsr..and all this question keep pop up in my mind...
1. what rpm will my turbo start spooling?3k,3.5k or 4k rpm?i targetting to spool around above 3k but not as late as above 4k rpm..
2. will my torque number increase or decrease with the same boost level before?honestly i scared with high number torque as i find out that higher torque do stress out my drivetrain(gearbox,driveshaft etc..)
3. i planning to use tubular exhaust manifold(banana)..will this effect anything?spool time,output,flow?will this thing be affected?
4. i also plan to run the highest boost as i can and from there set the optimum boost for my daily use..will my full boost rpm be affected as well?
5. do i need an ic upgrade?now using that ugly jasma thin intercooler..do i need to change them and use bigger or thicker oem intercooler?
hope someone can enlight me a little..tq
