Got this r31 silhouette flood car to rebuild.

[25RBGT]

New reg arrived, no use hooking it up rail is coming out with injectors.

Sort out this bumper over next few days, finish restoration on headlights. 
post results of both shortly

You should throw rebuild kits at the injectors while they're out...they pretty much need it anyhow at this age in life.. 😃

Yeah mate, I’m not 100% how much damage this water has done to the crank and internals. At the moment my mate is sending me whole inlet man with injectors rail to bolt on. 
in the future it’s gonna get a decent amount of boost prob around 400-500hp so this motor is just gonna get it on the road and registered. 
see how it goes. Stage two turbo is still a long way off.

Fits many of the circa 1980s Bosch injectors. The gauze screen eventually gets (partially) restricted with fuel deposits, new base seal & Oring (they go hard), and the spray hole in the plastic pintle cap erodes after decades in service.

For the numbers I want from my rb30 I’m going a different ecu and it will be getting new injectors at some stage after it’s in the road.
But for that price, they will 100% be getting a service while they are out. Thanks mate

It's a fun job...did a little write-up here --> https://forum.r31skylineclub.com/index.php?topic=159279.105

FTR, smoothed the idle out and the rb30 was more responsive...manifold vacuum at idle came up a bit (likely the base Orings leaking), and spark-plug colours evened out. An interesting little test, is to grab an eye-dropper/pipette and put a couple of drops of petrol in the old gauze filter, same again with new ones...see how long it takes to drip through 😃

Thing is the results are inconclusive because I replaced the injector connectors and fitted the intake runner spacer at the same time...but when you see & test the old gauze filters, there's little doubt this would've pushed fueling a little bit towards the thin side...

....washer bottle cap, still available last time I checked.
