yep exactly right.

yeah my ecu had been reset since the vf34.

yeah u def wont get the most out of the turbo, but it still is a big improvement over the td04. Lag wasnt too bad, kicked in round the 2,600-2,700 mark, could live with that.

prolly coz ur a bug eye owner

yeh its not as bad on the gc8's as compared to the later models. before that i also ran a vf28 on my other rex without a aftermarket ecu for over a year, then had a safc fitted which is a cheap fix. But anyway if you can afford it def get something like a link or autronic fitted n tuned. Will get the full beneifts of the vf34 then too.

Yes, a set of re-designed fuel feed lines with a central fuel distribution block (and return) with a good adjustable regulator (Sard?) is a very good investment in engine life balanced with bigger Kw.

Just be sure not to fall into the cheaper option trap of using -6 fittings and lengths of the matching braided hoses as these are much larger volume and you should re-calculate the line pressure to compensate.

In other words the 'known good' fuel pressure reading that you set may not be whats happening at the injectors.

Try to use lines that match as near as possible the length and volume of the Subi ones.

Best bet buy a quality after market product.

Lets see.....

MY00 GC8 with a dodgy Air Flow Meter plus an Oiled K+N APS CAI + factory JECS ECU = rattle rattle pop fart

At the very least either take it real easy or clean you AFM NOW!!!!
Your definatelty asking for trouble with a MY00 factory AFM plus Oiled filter. This has been proven many many times.

440cc Injectors will be fine.
Get a Walbro pump tho.
Only get a Sard FPR if you really want a bigger safety margin due to high duty cycles on your factory 440cc's at big KW levels without getting new injectors.

If duty cycles are extra high I would get bigger injectors now and don't get the Sard FPR. Ask your tuner regarding duty cycles expected with your setup!!

I would consider the parallel fuel rail mod for peace of mind though on a MY00.
