We are currently running 88251 cams, but are getting another set of those cams reground to a genuine toyota mild permormance setting, should be somewhere around 270 degrees at .1mm lift (280 degrees total duration) I don't know the specs for sure. 10.5mm ish lift too.
THis is costing $120 for the pair, but is not a cosworth (welded) type regrind, so new shims will be required, but at $5ish each, its no big deal.
We are using these with 9.7:1 pistons with a mild port polish 88270 head and old style 40mm solexes.
The carbies will probably be a restriction, but regency are not our friend, so an efi conversion is off the cards.
DO NOT TELL REGENCY that you've got efi gear on a non efi block, it will cost you thousands to get it legal.
Just tell them that the whole lot is EFI, and hide the computer behind the glove box and say that its all 18rgeu gear if it isn't.
Anyway, I've been told by someone who seems to know what he's talking about that changing cams with an AFM set up screws with the efi big time.
The AFM and computer don't cope with anything other than stock.
You could go for a UNI chip type thing, which can be used as a piggyback to your stock computer to readjust it to suit the change.
The better option is to go for a MAP sensor set up, holden (yes, yes, I know ) camiras have a MAP sensor and can be used for an 18rgeu with better cams.
With low compression pistons, higher duration cams may lose quite a bit of bottom end benefit. usually, from what I've noticed, people take the compression up as they take their cam dration up, that way they don't lose too much active compression (and bottom end) while reaping the top end benefit of the higher duration cams.
If anyone think's I'm wrong, please correct me.
Guy, if you want any 18rg help, don't hesitate to PM me, I'll give you my details on request. We've rebuilt one of these suckers, so we know a little bit about them now.
