Spoon Sports Ecu related advice required

[Zen]

Just purchased a spoon ecu and about to fit it in my facelift ek9. I have all breather mods sorted.
I'm aware that more mappable ecu's exist but I have no interest in these so please, none of the....you should have bought this or that.

I've searched this forum and the following questions remain unanswered.

With the increased rev limit at 9000rpm what engine parts could or should be changed to increase reliability?

What parts would see me making more power after 8400rpm with this spoon ecu?

Thanks

valvesprings and snap-fit retainers are all that are really needed.

Some will opt for a stronger timing belt from Power Enterprises/ Toda/ GReddy. They are all good. Just depends on what color you like...

Spoon cams will probably be the next option if you want to make more power above 8400rpm... but yeah..I'm going to say it anyway.... Hondata/Crome would have been the better option since you're looking for power.

Power = running bigger cams + compression + bigger injectors than what is available from Spoon....where the Spoon ecu can't handle it.

RagingAngel you don't think factory CTR springs/retainers can handle 9000rpm? I'm currently going to 8900rpm on my setup with stock CTR head with just new guide seals and a 3 angle valve job... your making me

I didn't say they couldn't...

he asked what parts would help increase the reliability

I don't think you have anything to worry about blinx unless you're running some weird combo of huge lift/duration cams with your turbo haha.

I know for maximum power I should have gone for a standalone ecu but really want to stick with spoon or mugen parts as they are widely accepted as quality and proven even if not "the best option".

I'm real happy with the performance of the car now but want to be as close to 100% sure that the reliability is there. If whilst replacing parts for reliability I can squeeze out a little more power then great .

I too would like to know if factory CTR springs/retainers can handle 9000rpm?
I've read that the "B16 is oversquare with the shorter stroke so it 'should' be able to rev higher and more freely than the B18" for example.

Cheers

Check the graph I have attached.

It is a directly from the Spoon Sports N1 endurance car that was purchased by A&J Racing before being sold to my friend in Chicago. The motor is full Spoon prep B18C with NO cams nor camgears as that is not allowed by class rules but does have the intake, 4-2-1 TWO piece header, throttle body, 2pce head gasket as well as a catch can and custom titanium catback as the stock fuel tank has been replaced by a fuel cell.

It also has a Spoon ecu.

Car in current guise:

And from about a year ago:

The thing to note here is that the spoon ecu is running ridiculously lean at some points and despite having more or less the full Spoon catalog of parts, the Spoon ecu is not even fit for its own setup.

I do not have the current graph but it has since been re-mapped with hondata (or was it crome?) and it makes even more power and runs even MORE reliably.

This for me certainly solidifies that a static ecu has no place in today's current depth of tuning.

Regarding the stock springs/retainers, they are fine if you are using the stock cams and you're revving up to 9000rpm.
