I made 270rwkw on pulp using the stock item.

Great response, no issues

There is a LOT of info regarding the viability of plenums etc.

However, in my opinion (as with after market exhaust manifolds) i feel the money can be spent elsewhere long before the need for a plenum has arisen.

Use the original plenum and heat wrap the piping from the cool side of the intercooler to the plenum. Works an absolute treat in keeping temperature down. Forward facing plenum IMO is really pretty pointless "wank" factor sort of execise. I would really only use one in the case of a conversion where motor height was an issue. However I have heard of the Greddy one making some minor gains but again its not really worth it for the price. As R31nismoid said money can be spent a lot better elsewhere

      Ahhh, I need the whole head unit. I definitely needed to roll back through and review your setup, ha ha! Neat setup they have going on. I just need a full double din head unit. But I want good and responsive. I might have to review what the likes of pioneer have out these days.

      34 de+t conversion using s2 stagea automatic transmission, engine harness and ecu

      By albyz34gt · Posted

      Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys

      Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?

      My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.

      There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.
