fuel pump and injector

[lan evo]

what kind of fuel pump and injector suitable for my upgrade?i wanna put 272 cam and retain the stock turbo.

thanks

i think as long as standard turbo is retained,and only cams upgrade....the stock injectors&pump can handle.upgrading cams usually need to upgrade the ecu.and the fuel aspect,at least need adjustable fuel regulator to increase the fuel pressure.

upgrading the big cc injectors&high pressure pump usually necessary when use bigger turbo.

im not an expert anyway. ;)

what engine...

if just cams then no necassary to change injector unless ur boosting quite high....but then again b4 boosting metal head gasket n "so-on" mods have been done or not...if just cams no need change but if u wan to -+200 % of ur standard injector upgrade if ok....lets say from 510 no need to go for 1000 if ur not above 2bar...but can use oso 1000 its just u have to get a management to control it...if not...rugi minyak...or engine running rich kaw kaw....

fuel pump is adequate if the fuel pressure don drop too low...if drop very low then change to those "power" or "walbro" or Sard brands...those merc bosch oso can...but cannot fit lar...need mods not just PnP...

fuel pump, walbro or power 255lph = WHHHHHHHHEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE omg. suggest you try other cars with the pump, see if you (or your family/gf) can tahan

 

[antonio]

not onli that...ur pocket can tahan or not....bcoz it does not come cheap unless u own a gold CC

actually walbro 255lph if purchased online is <rm400 shipping included. the shops in sunway rapes you on the price :(

boosting 1.1 bar,got metal head gasket

i think bigger turbo gives more satisfaction than 272 cams.

the problem is big turbo needs more upgrades.especially the injectors,pump and ecu.

standard injectors,pump,cams,intercooler can support slightly better flow TD05-20G,just do the ecu.anything beyond TD05-20G needs serious fuelling&ecu upgrade to make sure the internals are safe.

search from www.google.com or from ebay

i think both turbo and cam upgrade should go together, they should complement each other. search other forums, there are a couple that have done lotsa dyno testing with cams on stock motors iinm

dolly.

if put 272 cams,so can pull easily too 7500rpm.but with standard TD05-16G,i think it cannot go high boost.which one come 1st when flooring the throttle...boost limit or rev limit?

boost too high = engine blow +turbo blow(sumtimes)
rev to high = engine blow (conrod,bearings may not withstand) :(

pathfinder, yes 272s will let you breath better up top, but whats the point if your turbo runs out of puff 1k rpm before the 272s get to shine?

td05-16G (big G) if you look at the compressor map is pretty okay for high <1.5bar boost, but this also depends on what rpm u intend to run,

and like you said u'd prefer to upgrade turbo as it gives mroe satisfaction, true, but how about lag? and if you put a big turbo that starts to shine at high rpms, and you dont have big cams, then ur killing urself again.

thas why i said, both go hand in hand

partly agree with cams not needing as much upgrades tho. if you go for hks cams then yeah thas all you need, since the lift is not as aggresive, can still use back the stock springs and retainers, but not true if you use cams from tomei/jun/pipercross etc. also, depending on rpm, might need to beef up the internals/ bigger/better porting headjob

 

[pathfinder]

that's why i only suggest the TD05H with 20G.not as laggy as TD06-20G. ;)
