"EBM"
Yes, I have the original D16Y8 SOHC VTEC EX motor.
Yes, GSR fuel injectors fit into our engines. I don't know how much more fuel they flow - but the GSR engine is a 1.8 liter, and ours is 1.6 - so I figure it's flowing more fuel. They cost me 100 bucks total off of one of my friends that took them out of his motor.
PORT MATCHING THE INTAKE MANIFOLD...
(the EX t.b. opening is the same size as the EX intake manifold... so when you get a larger SI throttle body - you have to open up the intake manifold so it is the same size as the SI t.b.'s opening... if you do not - then you will not benefit what-so-ever because you will not be flowing any more air.)
1. Un-attach your intake from the EX throttle body.
2. Un-attach both sensors, throttle cable, and coolant lines from the EX throttle body and unbolt the stock EX tb from the intake manifold (only 4 bolts)
3. You will need a new factory SI throttle body-to-intake manifold paper gasket. You then slide this paper gasket onto the intake manifold. Trace the inside of the larger-diameter SI gasket on the intake manifold(this is the line that you will grind the opening out to - it's only a couple of mm's larger)
4. Stuff the intake manifold with rags to prevent the metal chips from getting down into the head.
5. Bust out your dremel tool - throw on a carbide bit- and get to grinding. Keep grinding the opening larger until you reach your marker line.
6. Pull out the rags and vacumn the out any remaining metal chips or dust from the inside of the intake manifold.
7. Put on the new SI t.b.-to-i.m. gasket on. Put on the SI t.b. and bolt it up. Re-attach the two sensors, throttle cable, 4 bolts, and coolant lines. Re-attach intake. The EX AEM rubber intake-to-t.b. connector is a tight fit - but it will fit. You're done.
Over-all a very very simple mod.
You say "no one has the same future mods as I want" ... well what exactly are these mods? I'll try to help you out if I can.
