I am finishing up a b18b1 swap in a gsr body and need help with these last couple of hoses and where they go...the engine was converted to obd0 but I converted it back to obd2 and am using a gsr throttle body




and also this hose from the thermostat




Also can anyone verify that I got the heater hoses from the firewall in the right location..

block the vacuum ports on the throttle body, OBD2 B18B doesn't use those. The fitting on the bottom of your TB is for the coolant bypass, your IACV also has the same fittings and the small fitting near behind the thermostat is also a coolant bypass hose. They should all be interconnected together though I don't know the correct routing off the top of my head.

ok, just checked a diagram for the coolant bypass. looks like routing is from the thermostat fitting to the fitting on the IACV nearest the solenoid, then from the other IACV fitting to the rear most TB fitting then from the front TB fitting to the fitting on the upper radiator hose casting connected to the head.

your heater hoses look to be connected correctly as well

ok I got it all but what about the nipple on the water pipe under the intake manifold?

where does the nipple on the water pipe go because I am using both ports on the iacv already

1 wrong section...2dual throttle body by chance do you mean ITB's ? there would be 4 no such thing a dual throttle bodies on a inline engine

hi, i dont have any info for your swap but im looking for info on the b18c1 swap from a 96 gsr into my 96 ls trim tegi im doing, and i need to figure out where some connectors are going for the harness and cooling system, i took a video but its kinda doodoo but these pics give an idea.

but its two coolants inlets/outlets behind the engine and under the air intake, ones on the thermostat and idk which is in or out, two below that near the rear trans mount and fire wall, a hose to a box behind the engine with a red 90 connector and a vacuum line on the intake manifold/throttlebody.

some connectors, two above the alternator grey and green, one above the throttle body black w/blue insde, and one by the connectors that go to the ecu grey w/white inside.

idk if anyone can help me figure out which goes where or what im missing for connectors



need to know where these three go .


the two inlet outlet pieces, and this hose i put on what i think is a vacuum line connector, hose comes from the main coolant hoses on rad.



the grey and green connector above the alternator, no connectors near it



this connector on the main three connectors going to ecu thro firewall, no other connector for it, dont know if i need a new harness piece that goes thro the firewall



these two down here for cooling i assume, bottom one runs under the intake to somewhere i cant see rn
