how much to swap the rb20det into my series 3? a rough idea?

[180boi]

also it doesnt have to be an rb20det thats jsut what i found myself, havent much experience with turbo r31's i was previously a silvia guy, anyway 200kw on anything sounds pleasing lol and in the light r31 id be happy with anything making 140+

I'm pretty sure the comperssion of an RB30ET motor is 8.5:1.. but the RB25DET is 9.0:1 as you said.

RB30ET is 7.8:1, RB30E is 9:1.

Even on 98pulp they do tend to ping a tad with 15degree's static timing so they really do need an ecu remap which is possible with the vlt ecu's.

Or pull a few degree's out of it.

The cam specs are also slightly different.

Providing the rb30e bottom end is in good nick to start off with there's no reason why they don't push over 300,000km's.

Sky30 is a testament to this with the purchase of his s/h rb30e motor that did 270,000km's, pushed 240rwkw through it for ~20k then 300rwkw for another 20k and now 380rwkw. Strong motors providing they aren't detonated/leaned out or over-reved; its all in the tune.

I would do it; just be sure to run it up on the dyno to ensure its not pinging its arse off and it will be all good.
