Greater thickness than 1.2-1.3mm is to drop compression. 1.5mm gaskets drop compression. Multilayer steel would go with your build. ACL seem reasonably priced, however in "Premium"gaskets there appears to be satisfaction with Cometic. Tomei and other gaskets seem pricey. If you've bored 20 thou convention is to use a 87mm gasket.

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      Hi. This is just my curiosity because iam sure the tuner figure something out...but either way i want to ask. The "problem" is that the Nistune ECU (Stagea FW and RB25DET NEO from Stagea) sees many times the speed than the speedo does(he says the speedo show 120 km/h - correct speed and the ECU shows like 510km/h ) I told him that this car/tranny getting speed from rear diff. If iam not mistaken the RB25DET NEO "need" to see tranny speed sensor? (my tranny has the plug for it). So couple of "question" If he connects/wire the speed sensor to the tranny...are the signals gonna intervene and if...what if he disconnects the rear diff one and the speedo stops working? Or the "new" sensor from the tranny "take over" and will not going need the one from diff? As i said i know he figure/get that done...iam just curious to know what are the solutions 🙂

      Your IACV is set to idle too low. You need to adjust it via the screw Duncan mentioned. From memory it should be 650rpm with the valve electrics unplugged. What is it trying to idle at with the IACV plugged in?

      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)?
