ok guys im only new at this and i dont even know if i am in the right place but here go's.

i have a 1994 r33 rb25det s1 and my check light is on the dash...

the light comes on for a while then goes out for about 5 sec then appears again for a min or so then go's out for a couple sec and so on

i have done some reading and i have learnt how to bridge to loom to do a diagnostic, but the problem is the engine light dose not flash any codes at me when i do this

can anyone tell me why this is and how can i get the codes out of my ecu

this is my first skyline i have owned

any help will be muchly appreciated

ok maybe you arnt bridging the right pins, turn your ignition on and when you bridge the pins the engine light will turn on, keep it bridged for a few seconds and then release the pins and the engine light will flash your codes at you. The only alternative is to hook it upto a consult program an a laptop using something like datascan, you will need a special cable to do this

What ecu are you running? The consult port will only work with a standard ecu.

As for the port itself, it's called 'Consult' and is pre OBD2. You need to get a special cable and software to use it. Check this out:

that is a very good point, if you are bridging those exact pins in the picture and nothing is happening you may have an aftermarket ecu, some are a full replacement and some just change the circuit board in the original one, rip the passenger side kick panel off and have a look, if you see apexi or something like that on it then its aftermarket

      And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.

      No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.

      Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.

      2630s work perfectly well. There is something to be said for just using the 30 head, as it saves all the pain of the conversion, still makes tons of power, still sounds cool, etc etc. 2630 will obviously make more power again, but the differences are not stupidly big. It really depends on whether you're racing for sheep stations or not. If it's dead serious, then it's a 26 head. If it's just for fun, it could go either way. But the 26 head and the effort to get it set up, etc etc, is part of the fun.

      I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.
