1996 240SX RB20DET

[Chevvy123]

Alright! So I bought a 96 240sx that has a rb20det swap in it the other day. I was told that the car has 550cc injectors(idk), and a front mount intercooler but was stock otherwise than that. First thing I noticed was the obvious boost leak. So I found and replaced the coupler that had the gash in it.

Moving on from that, I found some company named Twisted motion that sells a few parts for the rb20. Any info on them or experiences would be great. Anyways, they have a bolt on turbo that I'll get just to try them out. Its $400 bucks so it's not that much. I'll be needing a coil pack upgrade as well. Whenever I'm on long trips, if I turn off the car, it won't start until it cools down.

A few things on the car do not work.
--temp gauge... It just always blinks red...
--boost gauge... Does nothing at all
--A/F gauge... Also does nothing at all...

Otherwise than that it's a great car.

Future upgrades
--turbo(of course)
--brakes
--MAF
--Limited slip diff

Cant think of anything else at the moment. Cheers!

So for brakes I will be going with the Full big brake kit from Arizona Z Car. They have a 6 piston caliper for sale that's only $1400 for the fronts and $800 for the 4 piston rears.

When you say it wont start after it's hot? the car won't crank? or it cranks but won't fire over?

[Chevvy123]

It doesn't crank or anything. All the accessories and whatnot work, but the starter doesn't engage.

[Yellow4g63]

Did u get the starter tested yet? Sounds like its going out.

[Chevvy123]

No I Haven't gotten it tested as yet. I figured it might be the starter that was going bad. I'm trying to diagnose a few other electrical problems before I move on to that. Like my temp gauge... The red warning light just keeps blinking, and it doesn't show anything. The boost gauge just doesn't move at all... there is a signal going to it, so I'm not sure why it doesn't work....

[Yellow4g63]

What bring gauges?

[Chevvy123]

Brand? Greddy

[Yellow4g63]

Auto correct fail. Check the wiring, also look for the map sensor to the gauge. Hope your not missing the sensors.

[Chevvy123]

Yea I'll check it out in the morning, But everything should be there. I didn't trace any of the wires, but a quick visual inspection showed that they were all there.

[Chevvy123]

Checked everything for the gauges... Still nothing... Moving on... I'm trying to change out all the split and or cracked hoses on the rb20, but I can't find the hoses anywhere.

[Yellow4g63]

post some pics of the gauge and the sensor locations.

You can get a new starter from autozone for like $70 no core, but they might have to order it.

My friend has been building my RB20 project slowly, cuz I work all the time. But He came across a Canadian guy who found a matching part for the US guys who need rb20 starters. Its actually a starter from a nissan forklift, they had 3 different brands when I went up there, I got the most oem looking one, and it seems to bolt up fine. I won't know how it cranks till next weekend when I put it on the engine hoist and put the flywheel,clutch, and trans on the block.

The part number he found was 23300-00 h10

Thanks Breadbox, I got a new starter so its fine now. I think I might have burned out the clutch on the car. I was at the track and did six perfect runs... On the seventh run, corner two, the car backfired and started blowing smoke... and stopped.
