Itr intake manifold

[delsol9000rpms]

Hey guys i have an ITR intake manifold with no TB.... so heres the deal.. my current motor is a b16a2.. i was just sussing out the install tonight and would just like to know a few things.. before you ask... yes i did search

first thing.. theres a sensor on the back of the b16a2 manifold. i think its called the vaccum solenoid?... the ITR intake manifold doesnt have this so i would like to know whats the go and what i have to do etc... heres some pics so you know what im talking about

THIS IS THE B16a2 MANIFOLD

next.. i have the ITR fuel rail and FPR etc... and i noticed the fuel rail between the ITR and b16a2 were diffrent.. just wanted to know which one would be better to use out of the b16a2 FPR and fuel rail or the ITR FPR and fuel rail..

if i should know anything else then feel free to enlighten me

thanks alot guys for your help... if i was unspecific anywere just let me know.

cmon guys doesnt any body know anything..? im sure heaps of people have did this upgrade before how did they get around it??

also... what is the maximum size a ITR manifold can be bored to suit a bigger TB?

first post changed... anyone kknow anything? any info is better then none

evap purge solenoid valve,just tee off a vac point somewhere else & screw it to your firewall & leave other end conected to charcoal canister.

use b16 FPR,unless u can get it retuned to the higher pressure,but better off with the B16 one,both fuel rails are up to the task.

dont know about bore,maybe 65mm-67mm before u start hitting idle passages?

/\ What Jason said.. :thumbsup:
Around 65mm is about as far as you can go with the std ITR intake manifold for reason stated above.

when you say tee off another vaccum point do you mean Integrate it with another vaccum hose etc? as for the fuel rails and fpr if there is no bennefit i will not waste my time or money tuning it for that... although it will be retuned with the new manifold an TB.... next ive got to get a TB,, ive been told if i use a 65-68mm TB it wont be affected by the fact that the Manifold bore is only 64mm??

thanks alot crxer and Adrian... much appreciated... the manifold is already bored to 64mm so i wont bother boring it anymore...

cheers guys

i reckon with your set-up go 68mm... port matched the manifold inlet... Im running 70mm skunk2 t/b on our b16a in the EG, there isnt much lag, depending on what combo you use..

Its make a nice power curve with no kicks..

can you use a throttle body which is bigger then the port of the inlet manifold?

[Benson]

Yes..!

thankss :) great help from all you guys much aprreciated

yes,just tee off another vac hose,close to the intake manifold if there is no spare port on the manifold for that solenoid valve.

both fuel rails are adequate,talk to your tuner about the fpr if u are not running larger injectors than standard & trying to push a considerable amount more power/revs out of the motor.There is about 8-10psi difference between the 2 regulators.As u have prob worked out it is very easy to just change the fpr's over at the time.

yee well atm its not being starved of fuel or anything... i dont really see the point of puttin it on to be honest.. waste of time and money for me.... no pointt upgrading my fuel system if i cant get anymore air into the engine...

do you think its a worthwhile mod?

[CRXer]

sorry,i dont know your engine credentials & your tuner will be able to give u better info on where your injector duty/duration is running at,so just take it with you when u get it tuned,i dont think u will be changing it however.

well we willll see what happens ayy thanks alot for your help again mann...
