i got those gsr injectors.. for a good price..
as for the fuel pump,. got supra's also for good price..
now looking for adjustable fuel regulator for good price also.. heehe,....
the itb adaptor is being fabricated in subang industrial park... really burn my pocket. as for the trumpets... havent decided on making one yet.. it costs as much as the adaptor... ouch!!!.
Great to hear tat u r goin to install ITB!Tis is the things tat u need bfore installing ITB:
1) adjustable fuel regulator
2) walboro 255 lph in tank fuel pump
3) 390cc injectors
U might think y i suggested the 390cc injectors?It is becoz when u r using management to matter how big the injector is, it stil can control the fuel!Don't use stock injectors, when tuning a car, we must not try to use the management to push the injectors, tis is not a good idea! we must use bigger injectors n trim it down!
This is all i can suggest for the time being n hope it will help u....update us v d results after u have installed the ITB
Cheers
Yup gsr injector was good for 220hp machine,but if the setup is not radical mivec injector will do.
nice to c tat....il ov itb also, but its damn expensive, i guest all 2gather atleast 5k rite?
mine im still struggling with T&C :P and not much hav been done since i start my new job.
nice to hear from an itb lover!!!
As for the cost, maybe close to 5k tho well lets take a rough calculation
toyota itb =300
custom adaptor =approx. 1300(ouch)
bellmouth trumpet =440 (aluminium, no kidding)
ems+tax+installation+tune =approx. 1800(in my case its Megasquirt)
fuel delivery and such =approx. 500
total =approx. 4340
for me its a huge project.. i came in the shop with a 4g93 head. now ended up swapping with mivec block and head.. crazy ah? since the block is better in high rev than sohc 4g92block and the nature of itb in high revs. thats the reason i changed
well.. i do have time now.. using it to the fullest...!!! money can dig there dig
here.. hehehe
my worries are now on the tuning... well its still a long way there...
hope everything goes well.. only thing is $$$... where to dig sumore?????
hope this thread lives on and assist others like us.. with the help of our sifu's ofcourse.. (not me)

cheerio!!
Tuning is easy providing you have done these things;
1) head ported correctly
2) Compression is upped
3) Good cam setup
4) Good xtractor design.
If you dont port your head there will be no power, if using standard compression low RPM will bog down, if using standard cam power will taper off early, if u using mivec standard manifold engine will be not revvy as what (itb) supposed to do.
You have to expect these factor when installing ITB,,,,1) Super quick throttle response which means 1st and 2nd gear should be zaap & zaap redline,,redline.
2) Properly flow ITB will "maxed" out mivec injector 3) Your high RPM must climb faster than the mid one.
If you achieve those 3 attributes,,,meaning that your ITB design & tuning is damn "cun", if you happen to feel "sluggish" or termenung,,,that means you have to "redesign" the ITB length and size. Good luck
A bit of a secret here,,,example 200bhp ITB can always outrun 220bhp cars with intake manifold,,,reason is bcoz it can revs out faster than the manifold do,,,,get the idea:shades_smile: .

What do u mean by "using standard manifold engine will be not revvy as what itb supposed to do"? Do u mean the extractor?? Coz once fabricating itb,.. there wont be the standard intake manifold anymore.. Pls clear me up here.. Assuming its the extractor.. Im thinking of getting a 4-1 design.. what dya think?
