No worries Steve, thanks for that it was a lot of useful advice and info..
Im now uncertain what path to take the old 18Rgeu, on the search for more power.
If i went to regency i wasnt going to tell them about the internals! when i bought the motor i was under the impression that the motor was a complete stock 18R-GEU, but only after finding bent valves we noticed the domed pistons. I am not sure where they are from, but while looking at the lower part of the timing cover there was an -88250 stamped in it which leads me to beileve it is an 18R-GU(88250) with the efi(88270) head. still uncertain.
All the EFI is Factory 18RG apart from the AFM(22R-E), and fuel pumps. Analog fuel-only ECU, electronic dizzy, and spring-type flap AFM.
Hmm maybe i wont mess around with cams at present, better to keep it as economic as i can at the moment anyway. I may continue and save up for a custom turbo kit map sensor etc, but it may end up costing more than an S15, GT4 or similar front cut... 
One reason i brought up this topic is because my car suddenly died whilst driving at low RPM a couple of weeks ago, was at about 2000Rpm in 4th and then POP! out the intake side.. ecu auto cut off.
Couldnt work it out because was still getting plenty of spark and fuel, just wouldnt start and sounding foul.
Once home took off rocker cover and crank, to find that the exhaust cam is not turning!
Steve, u may be able to remember the short timing pin/dowel that aligns the cam to the cam gear, This small pin either snapped or dislodged itself from the press fit. But i fail to see how it could have moved or fallen out becasue the large washer on the front of the cam gear covers it almost completely.
We have tracked down another dowel which will probably fit, but im just hoping no other damage would have been caused to the block/internals.
Did you use new valve springs in your rebuild Steve?
anyway,
thanks again for the advice!
keep u updated on how it goes,
Guy
