D, that sure does sound expensive!! The thing id be worried about by going so big with the a15 is i would want it reliable for the future, by trying to get that much out of an a15 i cannot see its life being very long... and more so it would need constant rebuilds, im hoping to have my motor only needing a rebuild every say 2 years or so, maybe longer...
I know using webers is probably a pain because of the need for constant tuning, buttttt ive always wanted them so thats what im going to use haha.

I would have thought the same thing Nickmitty, the old 4 speeds dont have much meat on them. Im hoping to do the dellow conversion for the celica box later on down the track.
As for the turbo SC side of things, for now i would like to leave it NA perhaps down the track a nice turbo set up would be sick.

I like your thinking with not boring it too much Sikyne, does leave the engine with plenty more chances to rebuild, in saying that id still like to bore it out to 1550-1600. However if boring it to that means it really does reduce rebuild times hugely id be happy to go with the std bore size.
I was hoping to have the engine rev to around 7500-8000 rpm, i would have thought 8000 may be a little much, but i would be keen to get it up around the 7500 mark. In saying that if i were to aim for that rpm where abouts will my came begin to come on? As well as that would you recommend modifying my current wade 140 to be a little more suitable?
Also i have a set of stewart wilkins extractors which seem to be very nice, the exhaust thats on the ute atm is fairly new it has a hot dog about half way with a muffler toward the end width is 1 and 3/4 inch from memory.

Whats the cost on a set of arp bolts going to set one back?

And if i were to bore out the oval ports and match port a manifold would that be something to look at?
