Hi guys,
I m currently in the planning stage of a bolt on turbo for a 4g15 efi engine on a proton wira. Im still in the designing and idea stage,just want to bounce some ideas about and see if its feasible and what are the modifications that need to be done.Im hoping more of you senior members,especially those with experience in turbos to give me some constructive comments.
Here are the parts im able to source if i decide to go ahead:
-TD04 single fin
-GSR intercooler
-Turbo manifold
-Intercooler pipings
-Exhaust downpipes and other connections
Ive friends in workshops who are willing to get the piping work and other connections done for very minimal,what im concerned in is the fuel supply requirements.
What i dont know is the stock 4g15 engines fuel pumps maximum pressure and the injectors max cc.
Besides that,whats an appropriate AFC that can be used effectively for tuning.(Currently looking into SAFC)
Please bear in mind that this is still in the planning stage and im just trying to gather as much information as possible.I dont really want comments like change your engine or dont waste your time as ultimately this is my decision,not yours and Im intrested in a BOT,not swapping my engine.All others are welcome to discuss,help,give constructive comments and learn together.
Thanx guys.
Forgot to add, intially im looking for a modest 0.3bar of boost.Sounds pathetic,but i wanna learn to walk before i can run..
(Any one with a BOT 4G15 who is willing to spare some time to show me his setup will be treated to some Starbucks and hailed as god
)

)yeap, all the setup u mentioned feasible...
dont forget ur BOV... u need to stand out from the crowd and be noticed when u have a turbocharged engine... heck, even tiny L2s blowing their BOV a few times in a vr short stretch....
btw, ur car is svdo rite??... safc wouldnt be helpful here i guess.... couldnt think of alternative fuel computer now which can "piggyback" ur svdo, unless u willing to go for standalone ecus... hehe...
compression ratio... ahh... as we all know forced induction engines need low compression... perhaps u can source for thicker head gasket... of coz if its made of metal would be definitely better.....
as for ur fueling... i would recommend u to get uprated injectors such as mivec injectors.... good to upgrade throttle body as well if it is allowable (since urs is svdo, i dont have much info on upgrading it)... oopss....
i think ur oem fuel pump is manageable... get a fuel pressure regulator as well....
as for boost level, try be conservative and run it at lower boost for sometime and see whats what... if everything goes well, slowly increase ur boost level moderately...
bot 4g15 mmc quite alot and i would say rather easy project.... but svdo, i'm not sure...
