65458, Hmmm injector sizing.....for 2.4 swap, bank #1 Posted by BlueMoonEclipse, Feb-18-04 12:02 PM
Ok now many of you know im doing this swap (hopefully sooner than later) now my fuel setup from vacumm to 1psi boost should be controled by stock ecu..using its stock curves...for which i had hoped to use 20% bigger injectors to compensate for 20% more displacement...stocks are 235cc if i remember correctly...closest one i find are 252cc which is under 10% increase...next size up is 315cc just under 35% increase (way too much) ok so..i just need these to idle correctly and run at close to stoich before the EIC + second bank + 1:1 fpr kick in at 1psi (oh yah and i really am looking forward to see who will sell that knock stimulator for 1psi to make open loop kick in)
Im leaning on the 252 ones would be close enough for the ECU to compensate while in closed loop (should be an easy 10% adjust for it)...??
Suggestions? Flames? Rants? go ahead ..this is whats keeping me from being able to size bank #2 and calculate Preliminary fuel use

I bet 252's would be good. Stock injectors at stock pressures left me a little rich at 0 psi boost on a 2.0. 252's with a slightly higher fuel pressure would probably be perfect at 0 psi boost on a 2.4. However, there is only one way to find out.
