Hi guys, need advice, I can get a series 2 rb25det apexi power fc at a reasonable price, I have already converted my rb26 dett to a single turbo setup,when I look at the pinouts of the rb25det and rb26dett, they are fairly similar,my issue is the rb26 uses pin 106 for fuel pump control module and pin 6 for electrical fan switch; rb26 has two fuel pump control modules whereas rb25 had one.how do I go about this any further? Rb25 doesn't use electrical fan relay switch.

What do you call a reasonable price for the apexi fc. You can pick up fc's for600 ish fairly often on ebay for rb26/gtr's And let someone with a s2 33 buy the other fc.

Sa as in South Australia? No import tax on australian ebay matey. Im talking 2nd hand gtr/rb26 ecu, s in Australia. Postage should be 30 bucks max aussie wide with insurance.how much is this fc gor the the 25? Can pm if you dont want to make it publc?

Well still theydont weigh a lot so postage shojldnt be to bad. My opimion and suggesrion is forget the r33 rb25 pfc and buuy the one flr the gtr rb26. Be much easier in the long run trust me.

will work fine, just run 1x o2 and 1x AFM and you'll be fine. Just depin the intake air temp sensor on pin 36 as the RB25DET S2 pin goes to a idle switch or so which the S1 and RB26 doesn't use

    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
    • Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.
    • Got the front subframe and suspension in.    
    • If it's cold in summer, then no issue. If it's cutting out every few seconds and you're not reaching your target temp, then there's an issue. One could be the pressure switch and the other issue could be the temp probe inside the evaporator.
