TUNING THE NISSAN RB25DET (R34)
An excellent example of a factory RB25DET Neo (healthy engine with low mileage that was previously Automatic but was converted to Manual in the UK),
The RB25DET NEO engine would benefit from a set of fresh set of splitfire coils for future, otherwise the engine responded exceptionally well to a mild boost upgrade and tuning.
Next stop 400hp??? . Who knows what the owner will do next 🙂
Hybrid Turbos go well on these and would allow one to run 1.2/1.3bar comfortably seeing around the 400hp mark..
Something for the owner to consider for future

Steve and the art of making cars go really really fast
So as I have unashamedly plastered over many threads my GTT was remapped just over a week ago now. This was done by Steve from FC Tuning at Dynotech down in darkest Kent. After talking to a number of people I took my car to Steve in the end for a number of reasons, he is friendly and happy to discuss what you need, others have had good results and only said good things about him and since he does his work on Saturdays and Weekday evenings it meant I didn’t need to take time off work in the end. He was also able to fit me in a rather short notice which was nice.
The day came and off I went with Andy (armracing) for my 10:30 appointment. However this is where my car with its previous soft life of down to the newsagent at the weekends run around didn’t want to give up without a fight and Steve did battle with his mgihtly soldering iron and multimeter to tame the savage ecu. This did take a little longer than expected as one leg out of the 40 was being a bit of a sod. That along with a rather troublesome eve that was on before me did push time on a bit but if you don’t plan for this to take all day you are a bit of an optimist really.
After all of that we spent some time experimenting with different base maps. Started with a manual map but on an auto ecu that cause the hicas and TDS lights to stay on all the time so we burned an auto base map and off we went. I am not sure if all mappers would spend all this time getting the ECU board in place and then spend time experimenting with different base maps when time was dragging on as it was so that was nice.
We got it up onto the dyno and Steve started work on mapping the car. All the time he was happy to show Andy and I what he was doing which I am told is quite odd as most mappers treat their work like show magicians treat their tricks as if showing someone the secret suddenly stops it from working.
Anyway it was all going well until we discovered the plugs were too hot and the spark was being blown out above 0.7 or so bar. After a frantic plug changing session we started again and shortly after the car was ready to go. All in all the mapping itself took about 45 minutes once the ecu was done and the break for changing the plugs so udner normal circumstances the bill for dyno time would be quite small.
After the marathon 5 hour session Steve still charged what he said he would at the beginning which considering how much of a pain in the arse fitting the nistune board had been and the time spent waiting as Andy changed the plugs on a hot engine to some that ran cooler.
So if you want your car remapped and you can get to Steve I would recommend you at least have a chat with him as I have nothing but praise for him and his work and the fact that we literally had people queuing for him to do work on the day and how he is invited to all these strange countries like the one where they have mayonaise on chips means that people are willing to pay him to fly out and do the work rather than use someone local.
There was also some guy with Lithuania there but I get the feeling he lives in the UK and didn’t drive all the way to Kent just for a remap. Maybe I am wrong and Steve is just that famous
