Ok everything I read on here says not to expect much more than 250kw(335hp) on stock rb20det internals and still be reliable. What stuff needs to be changed out first and what order would you get it done in or would it be best to do everything all at once? Head gasket? Pistons? etc etc Is about 1.3 bar boost safe of stock internals?

i have a 230 rwkw RB20 mate and its been going over a year now of hard driving, plus i have seen another half doz with more than 200 rwkw and all are fine.

who cares if the motor is more than 10 years old, its how many km's its done that counts, if its geting up there in km's, a quick freshen up might be in order,

im going for 250 rwkw in a few weeks so ill see where the week points are.

      New Honda prelude at Goodwood

      Well, in the same way that you can't tell any SUV from any manufacturer in any size category from any other one, "sports" coupes now all look identical. Stand back and squint your eyes and the Supra and the 400Z and the GR/BRZ things all look the same. I was just thinking last night, when sitting behind a Subaru CrossTrek, that I have no idea what it is, how it differs from an XV, or a Forester, or an Outback, or anything else Subaru offer, and I couldn't tell if it was supposed to be small, medium or large. I contrasted that to the good old days, where a HQ Kingswood had familial similarities to an LJ Torana, but there is no way that you could confuse them, and how a bit later, the HX Kinger and the concurrent Torana and the Gemini all had familial similarities, but you still could not confuse them. Ditto the ugly Fords and Chryslers of the era. But now, a RAV4 looks like a Kluger, looks like a Yaris/Cross/whatever they're calling those stupid f**king things, looks like every other Toyota that's not a Camry/Corolla sedan.

      The Prelude doesn't look that bad without all that lens distortion in those pics. Makes it look disproportionate when it isn't. Actually I kind of liked it at the Osaka Auto Messe earlier this year.

      Ethanol Content Sensor - Always at 11%?

      Pour in the highest octane, non-ethanol fuel you can get and see if the readout changes. If it's dead bang on 11% then I would question the sensor. Another quick test, just take it out and run normal (in an american accent) gas-o-line through it and see if the sampled ethanol or lack of changes.   United E85 here in the land of drop bears does vary a bit, I've had as high as E87 (could be water in their tanks too, who knows)

      Yep. And if you ever do, you'll just have to deal with it then.

      E10 is pretty tightly regulated in percentage. Too much and engines can't adapt. Every incentive is against them to have too little ethanol though. The more ethanol the higher the octane.
