No you cannot just shove another turbo on and wind up the boost.

1. Get rid of the MINES computer

2. Get a Nistune

3. Then do a turbo, injectors, Z32 AFM upgrade

4. Forward facing plenum gives almost next to no performance benefits if any. Some say they lose power and torque. Make your engine bay look better yes.

5. Skids

Forward facing plenums do give some perfomance advantages, you reduce the heat generated at the top of the engine bay due to the intake intercooler pipe.Also shorter pipes means its a bit more responsive since it doesnt have to bend and travel twice as much just to get into the cooler. id agree with everything else kitto has told you.

she runs really well atm.bit of lag,have a manaual boost controller under the bonnet was wondering how it would go if i screwed the boost up maybe to 15psi...?

Nistune. Your at risk destroying your engine as it is. Just because it runs 'well' doesn't mean the AFR's are in check.

MINES computers are known to not have good tunes in them to suit Australian conditions.

how much do i need to spend to get a reliable afr meter and what brand?

Just get a tune dude. Nistune and get rid of the MINES computer!

An AFR gauge is not going to help you at all, none, zip, nudda. Factory 02 sensors are narrow band. If you hook up an AFR gauge to it is going to give you nothing but false readings all day every day.

The only way to have some what of an accurate AFR gauge is to use a complete wide band setup.

But thats besides the point. You need to ditch the MINES ecu and get a re-mappable ECU and then have it tuned.

Yep - searching always helps :)

Forward facing plenums do give some perfomance advantages, you reduce the heat generated at the top of the engine bay due to the intake intercooler pipe.

You'll find that @ 7000rpm and the airflow going on - that really is not a major factor in a road car when using its performance.

Peak hour traffic, yes, but performance has no place there.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
