Will a RB20DET head work on my RB20DE+t conversion? I am currently running the 'DE' head. I know there is a difference in duration between the two. The reason I ask is, I am considering a cometic head gasket @ 1.3mm to help reduce my 10:1 compression, I'll have the head off anyways so would it be beneficial to swap to the 'DET' head instead?

Only if you want to run high boost and its more than a nice daily driver with a lot more mods.

For a daily driver I would value the off boost response from the higher compression around town and up to 7PSI for that extra grunt when you need it.

If your looking to go all out it would be worth changing the head and the gasket and run 20PSI! LOL :)

(AS long as you have the supporting mods inc. ECU and dyno'd!)

    • I thought it could be an issue because the standard plate was flexing when stressed. Maybe the original gear set will hold a bit better without flex? Last time on the dyno it made around 670nm at the hubs. Now it have bigger turbo and better intake but have not been on a dyno yet. The car is being used from family trips to drag race events. So the shifts can be a little violent. It is grinding if I shift to fast so was thinking I should overhaul it soon.
    • From the factory on RB26s there's a fitting on the intake manifold collector/"plenum" that provides pre-throttle boost signal. That's how they did it back in the day, I figure it's fine to replicate it.
    • I would be surprised if that wasn't the issue. It's probably telling you, that even if you remove the plastic liner, you may have some other clearance issues that may occur too in some scenarios. IE, tyre to guard. It looks like someone has already rolled the lip, but you may still have issues in the future IE, turning and hitting a bump etc. The fact it changes how bad it makes the noise when you are going backward vs forward is highly indicative that it's the tyre rubbing. They do make a terrible sound, even if you're only pushing a project car that has a liner hanging down on a tyre!   Has the car been lowered? If it has been, what is the measurement from the centre of the wheel hub to the lip of the guard straight up?

    • Mark's a bit smarter than people give him credit... He'd convince the person that is to become dead, to drive him to the forest first. That way his car has no evidence in it, and he's free to dispose of their vehicle permanently how he sees fit too...
