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 :)

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.

      R34 Series 1 And 2 Front Reo Difference?

      By LjB123 · Posted

      Awesome to know. I have a Series 1, and When pulling my front bumper off for the first time i realised my reo/crash bar was a bit worse for wear, and was going to try pick up a better one soon just so i can replace it. Someone is selling a full series 2 front bar and brackets for a decent price, so was going to probably reuse my brackets and install the new second hand reo/crash bar. I also have a genuine Altia body kit to do up, spray and put on, and not sure if that will use the series 1 or series 2 brackets for the front bumper, so having both will be handy, and knowing i can drill holes out to make stuff fit between series is also handy to know!

      R34 Series 1 And 2 Front Reo Difference?

      By Kinkstaah · Posted

      I should also say that the while they are different the only parts that matter are the center headlight supports and center bar from S1 to S2. The center bar will work, but the S1 has holes that clips go through into the S1 bumper. So if you were super cheap you could simply drill the S2 bar. Same thing with the side/wings. They have slightly different 'clips' but can be made to work. The center headlight brackets however, cannot. This is also where the GTR differs, which has a different center bar, and different headlight supports (to either GTT system), it also has different 'wing' headlight supports which is what I am calling under the headlight. However those CAN be made to work with the GTT Reo for a GTR front bar by a small spacer and a drill/tapping a thread into the reo because the bolt positions are slightly different. So people only really need the center brackets to go between GTT S1, GTT S2, and GTR if you are happy to do some tinkering.

      rb20de neo +t conversion - boost pressure sensor needed?

      By GTSBoy · Posted

      If this, then this You can't really get away without it. There are hacks that you can do in Nistune, but things are much easier with the sensor than without it. If you're not planning to Nistune the ECU, then stop right now and add it to your plan anyway, because the ECU is going to shit the bed over the missing ABS and TC computers that it expects to see, and you need Nistune to stop it chucking all its toys over the side of the crib.

      rb20de neo +t conversion - boost pressure sensor needed?

      By kindaruined · Posted

      hey guys, so ive done a complete +t conversion using mostly stock parts on my rb20de neo r34.  Im wanting to know if a boost pressure sensor is needed? Seems like the engine cuts out when i try to do a pull and I have a feeling its because a boost pressure sensor is missing. I'm using a stock r34 rb25det neo ecu.
