Evening. Yes thank you very much all here in one piece! Drop me a text or something 07827814633 I need to send you some monies!

Removed the old one tonight. Bit of a bugger to get all that off in situ!

Hopefully I'll have some time at the weekend to get it on and start getting the car back together.

It does have a 99 spec Y pipe on it from what I can tell.

I was only asking as that silicon joiner is 95% responsible for secondary boost problems and tiny stress tears can be hard to see

Doz_FD3S · October 26, 2017, 08:51:01 PM

Yeah that's true. Other than a load of stale old vacuum/boost lines the only parts that I've found to be faulty are:

-Stock blow off valve,
-charge control valve,
-fuel system purge valve.

So hopefully this ccv is the last chunk of the puzzle and sorts it out and I get some reliable twin turbos!

Once this is sorted I'll get all the fluids changed, new plugs and hopefully have chance for some good drives before winter sets in and the roads start getting gritted.

Keep an eye on that boost gauge mate as 0.8bar is quite an increase from the 0.68bar it should be as standard for the factory ecu. The colder weather will no doubt increase this further. The standard ecu had two safety functions it uses to try to prevent you running lean, one is the rough as toast fuel cut which feels like you hit a wall. The other is more subtle as it will adjust your ign timing and this is shown as your boost drops off as you climb higher up the rpms.

Working properly you should have 0.68bar to the limiter

Really though the standard ecu is too slow to react and is the cause of many dead rotaries. There are many good ecus out there now and i would recommend putting one on your shopping list

Doz_FD3S · October 27, 2017, 08:26:53 AM

Yeah good shout. Once I've got the turbos working properly I'll record what the boost is doing across the rev range and see if it's normal or not. If not I'd like to understand why not and see if that can be rectified. Understand breathing mods will naturally increase boost slightly but I wouldn't have thought a mazdaspeed cat back and a panel filter would have that significant effect.

Yeah as Neil says...light WOT..really get ready to get your foot off the gas...these cars do not like detonation at all...
Have you had chance to look at your ecu case?... knightsports sticker / redom sticker usually indicates some tuning in japan.
Text inbound.

Yeah I'll have a mooch once it's back together as I can't get the pass door open the way it's parked in the garage at the mo.

Will go steady on the first drive & keep an eye on the boost. Hoping everything is normal!

Any update on prognosis mate?

I'm on it now. Just changing the last few vacuum/boost lines I can find before I put it back together. Taking some time as without the various ancillarys off the engine it's a right pain to get to!

Hopefully have it back together today if not nearly there.

Got a video of the boost I'll see if I can attach it.
