Rb25det Into Hr33

[BigGameHit]

Hello guys

Just last week I wrecked my ECR33 drifting at the track.......... fast forward a few days and I have a new HR33 with my old engine set.

the only difference I see is the small junction box above the ecu location on the HR33 only has one spot for the big plug and that's it. The small clip next to it reminds me of the body wiring loom for the s13.. this was blank as well when removing the HR33 engine harness.. I cut the small clip that fits into that location on the HR33 off of the ECR33.... If its similar to the s13/14... that is just for your gauge cluster.

basically my injectors which worked before the swap are not clicking when cranking or turning CAS by hand. I have not check spark yet as it was getting late and had to go to work in 3 hours. I am getting plenty fuel. Ill try another CAS after work.

anyone done this swap and if so what were any issues if any?

ps

running PFC not issues at all after the crash.

did you swap everything from the one car to the other? complete harness? or you are trying to patch in?

[BigGameHit]

there was nothing to patch. swapped the entire engine with harness over and every plug was plugged up. engine ran fine before the swap. the only thing disconnected are the grounds and power source amongst the obvious things to remove the engine.

no spark at all.

I used 3 CAS, 1 set of coil packs and 3 ignitors today.

been reading up on possible relay issues.... I directly powered and grounded the relay still nothing. Ill figure something out... events are coming up fast.

So your engine and loom is from a series 1 but is the donor a series 1 or 2? The power feed for the injectors is different and the series 2 doesn't have relay to switch the coils on like the series 1. The power feed to the switching side of the relay is missing in the series 2 loom.

no sir my engine is a S1. I fixed the issue about 2 hours ago

I had to power the injectors and cut the thick white wire on the relay next to the ecu and hook power up to the other wire not connected to the relay.
