This is the wrong approach. Take it to an auto electrician. We can't magically see what is wrong from here.

Holy 14 year thread dig batman.

Yes, but not road legal. I think the only Sparco seat that is ADR'd is the R100. Also, fixed back seats are not road legal in a coupe unless you remove the back seats & belts and get the car declared as a 2 seater.

I gave you the advice you needed. Watch the howto videos. Make sure you watch videos for the same series of hose & fittings that you are using. Use the correct tools. If you don't, you are making a failure.

Also completely unnecessary. They are a handbrake shoe. They don't wear out.

Buying cats "that fit" is not the only way to do it. The only way I have ever done it is to buy the cat I want, without flanges, then weld the flanges to suit the car.

Yes, but

And Slap, RB20s have an actual TP switch, not just a sensor. Idle is a binary input to the ECU. You can prove it to yourself. When it is idling, as you open the throttle (by hand, with your head above the engine), very slowly, you will hear the ECU double pulse the injectors just once. That's the ECU seeing the idle position switch input disappear, and is actually a good way to adjust the idle position switch on an RB20. The RB25s rely on the analogue from the TPS.

I will now quote myself. And thus, yes it is idling. It is not running on the main maps. And the original argument was whether the ECU added 15° to a static 15° for a total advance of 30°BTDC, which is not the same thing as the ECU using delta control to manipulate the idle speed.

You would be well advised to find a US importer of Jap stuff, or contact the buyers' agent type guys who live in Japan and source stuff to send back to peeps in foreign locations. Most of us are in Oz, and getting an RB to Hawaii from here would be more painful than direct from Japan. Japan also being closer to the source, must be a good thing.

Gents, When Slap is asking about closed loop, he's talking about closed loop fuelling. I suspect when Johnny Dose is talking about closed loop (in above posts) he's talking about closed loop idle speed control. So, talking at cross purposes. As has been posted before; At idle (ie, TPS closed, ~0.45v) the ECU is definitely in closed loop idle speed control. At idle, provided the O2 sensor is warm enough, the ECU will be in closed loop mixture control. But this often fails and the ECU will just revert to the idle fuelling map. At idle, the ECU does not change timing based on O2 feedback. At idle, the ECU adds AND subtracts timing from the base 15° according to its needs for idle speed control, but is aiming to run 15° and control speed with IACV wherever possible.

In that case, go your hardest.

Being LEDs, there's every chance that they suck at making light go on the road. They would also be a lot nicer with less shiny bling inside them. They would also draw the cops' attention (here in Oz) in seconds and earn you a defect. If it wasn't for all those things, I'd probably give 'em a try.

It's not too hard. The throttle is in the obvious place. The TPS is on one end of the throttle shaft and the plug is attached to that. You'll soon know if you've got the right one. Yes, but it is essential that the IACV is clean and working too. If you were to wind the idle down to 650 with the IACV stuck somewhere away from bottomed out, and the weather changed a lot, the idle speed could drop a long way. Or vice versa.

Having come from an S13, your Type 2 board is currently setup to run a CA18 or SR20 (or, given that you say 240SX, the truck motor that was in that). It won't run an RB25 without having the correct programming dumped onto it. Not just the maps, the entire ECU program (from an RB20, ideally, or even the RB26, conceivably). There is no reason to use emulators &/or burners when you actually have Nistune......

Yeah, I wouldn't be looking for anything more sinister unless the new #3 plug fails.

I don't know....it may just be me.....but this almost sounded like you were from Utah, or the Appalachians, or perhaps one of the cults. But welcome anyway!

Please don't tell me that there is a RogerSkyline. I couldn't take it.

High boost doesn't kill coils. It just exposes a soft coil's lack of ability to supply enough energy. Plugs don't die from dying coils. They may foul, but they don't die. The plug doesn't care if you're not feeding it enough energy to make a spark jump the gap.

I think it's not super easy to use the RB26 ECU on a 20/25. Whilst the 20 and 26 ECU are super similar, the fact that the 26 expects to see 2x AFMs and 2x O2 sensors and shit like that makes extra challenges that you don't need. The effort required to use it would be better spent elsewhere. Definitely worth checking the Nistune forum (or hopefully Dose knows off the top of his head) what the state of play is with that. I'm assuming the RB25 is running the original 25 ECU? So you can't use the Nistune board in that. You'd need an RB20 ECU to go forward, and as Dose said, you'd still be better off buying a new Nistune board, with the right program in it. Using the S13 one would require it to be redone anyway. You will probably find it easiest and best (although not necessarily the cheapest) to use a Haltech or other similar plug-in ECU rather than having to mess about with all sorts of additional needs to get Nistune working.

Now, or in the future?

Yup.

You don't need any pressure at all. Any pressure washer will do more than enough. You only want to wet the car prior to bucket&glove wash, then gently rinse it off. High pressure concrete cutter type washes are for boats and bro-dozers, not nice cars.
