Hi people

i am relatively new to forums so bear with me if i get some stuff slightly wrong.

I am currently building a 30det with a 25de head. I have gtr valve springs i am going to slap in(cause common knowledge is they float, according to my research)

I have full rebuilt the bottom end, crank collar, n1 oil pump, degalzed, new rings, polished and rebalanced crank, new bearings all round, new waterpump.

I have just managed to get a 25de head the other day, looks good but am going to take it to the engine shop and get it checked out to be safe anyway, can't imagine anything more worse than slapping it together and wondering why i keep chewing through head gaskets.

I have done everything else to motors bar one thing: headwork.

Now my question is this : the head has come with 20det r32 camshafts, and i am wondering if they are going to be any good, or if there is any much point to having them. I have looked up the lift specs:

http://www.tomeiusa.com/_2003web-catalogue/e090_camshaft-specs.html

the cam chart seems to say that the only difference is the exhaust cam. Its lift is .5 more and its degrees is 8 more. Is there any real benefit to this? or would i be best to just get some 25de cams and chuck them back in?

am i wrong or am i reading the chart right? cam work is something i havent dabbled in before, never been brave enough so any help is appreciated

thanks guys

      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.
