If you've got the a8 motor (99-00) 5g then you'd be well worth a tune as that could see you an exta 30-40bhp.

If you got the a5 motor (97-98) 5g, then I'd be with these guys and probably not worth it. Put some ATR cams in and with a tune you'd be looking 220-230bhp.

Excellent, thanks for the advice guys, I will reset the ECU this weekend and let you know how I get on.

What sort of money am I looking at spending on ATR cams? Am I right in thinking that ATR cams + Prelude Type-S cams are almost identical?

yeh they are the same, i bought mine from vtec direct, its worth contacting them, i will be selling mine soon but aother member on here is after a set and he put dibs on ages ago!

Thanks 4thgenphil, just been on to Vtec Direct and it doesn't look like they have any real Prelude stuff for sale. How much did you pay for the cams new? Did you have anything else done when you put the new cams in and how much of a difference did it make?

they werent new but from a fairly low milage engine, i think a7's tend to eat their cranks before you have issues with top end on them so there is more heads and cams that bottom ends

i also fitted an atr inlet mani fold and fitted a s200 and had it tuned, i got 230bhp @ the fly but i feel it had more potential if a different tuner did it !

i contacted vtec direct through accordr.org

^^^^ this
That's how I got hold of the a7 head for my build. He's prob right about the tuner too, phil has the same numbers as me and I'm on 10:1 instead of 10.6:1 compression. Bennyboy had similar work done with 11:1 compression and got 244bhp using the same tuner as me.

just a quick note on resetting the ecu. they never reprogram themselves, all that happens is the long and short fuel trims reset . this is calculated from the closed loop running of the car using your o2 sensor to monitor fuel mixture. the base map ignition table is the same, just the adjustments are reset. it will learn these as you drive not on idle.

Hi guys, I have managed to source some ATR cams. After these are installed, would I be able to take the car for a tune right away? Would they just remap what I currently have in place or do I need to source a new ecu?

No knowledge about these things I'm afraid
