Problem is i cant afford it all the same time, hence asking about running the atr head with my current rob chip. i can only just about afford buying the head and the cost that will incur getting it fitted. but i could probably manage saving enough to fit a mappable ecu and atr Im and TB at the same time and getting a tune done down the line a bit.

Nos will be far far down the line so dont want to wait on doing the other stuff.

This is when I'd recommend saving

Then you'll reach your end target sooner

Personally I would get a couple of power runs done to make sure all is well to begin with (unless U have had some recent mapping and dyno time)

You can tell a lot from a dyno run. If anything you will know where peak power is and you can shift up from there.

Something I have noticed with mine though is that shifting on the redline doesn't keep your car in vtec

is it possible to get better times by shifting the vtec about?

Its a sound idea, but as i said the head is going cheap so i dont want to miss out on it, and dont want it sitting around not being used! so i guess i will pop the head on and then save to do the tb im ecu and tune all at the same time. that way it will still cost the same (minus having to gasket the im twice).

reckon i might get myself a lottery ticket or 6 this week....

You're not going to get much out of just fitting an ATR head without mapping it though. Pointless in my opinion without the other mods, or at least a proper tune on a fully mappable ECU.

yeah i realise that, its more that i can do the IM, TB and ECU myself (obviously minus the tune/mapping), but i will need help with swapping the head. so if i can get it on the car and running ok its done then, and i can do the rest myself as and when time and money allows.

Am i right in thinking that putting the head on and running it with my current setup isnt going to do any harm? just wont be running to its full potential?

It won't necessarily harm the engine, but just fitting the ATR head without a tune might actually loose you power. Remember more aggressive cams demand more air and fuel, hence why the ATR has a better IM and larger TB.

yeah i figured that might be the case, but its the convenience of already having the head on so as soon as im able i can do the rest of the work.

"necessarily"? thats doesnt fill me with confidence...

Also, what sort of price do the ATR TB and IM go for?

And what will i need in terms of ecu? as i dont know much about it.

That makes absolutely no sense to me

But it's your time and money

ATR IMs go for £100 to £150 normally (Usually with all the paraphernalia). ATR TBs go £40 - £100 I think.

A P28 or P30 running Hondata S300 would be your best bet.
