sweet as...i ben lookin a turbos but bugga that i looks abit costly!! a nice cam,cold air,aftermarket raditor etc...advice?

Full rebuild of your engine.
Balance on bottom end.
Professional porting and gasflow on cylinder head.(Double valve springs and decent size valves)
Higher compression.(for street max 11 : 1)
Performance cam.
Throttle body direct fuel injection.

That would be my dream A15 before turbo.

Injection all the way. !!!!
I would suggest for the A15, to leave the cam if your on a budget, as on the a series you have to pull the motor appart (not just the head) leave that for when you do a full rebuild inc pistons etc. Go with some nice fine tunning like said below, electronic fan, electronic fuel pump, electronic dizzy and max air flow. then start on the head work like a gasket match for the inlet and exhaust. This opens the doors for some nice mods, like larger valves, double springs etc

i got 32/36 webbs.....wots better quads or fuel injection?

Depends on the tune & boost level. The pistons aren't really designed for it, but they will cope ok as long as you dont get too power hungry on the tune.

BTW: if you are planning to boost an A series on a budget, the A14 is the engine of choice. I considered going back to A14 from A15. The A 14 can take E15ET pistons without too many mods, giving you 7.5:1 compression and plenty of valve clearance. In the A-15 the E15ET pistons come 3.5mm out of the top of the deck (A14 is only 1or 1.5mm which is easy enough to get around)

The other bonus of A14 is that if you increase the comp for NA by shaving the head, it won't cause you too many problems when you go to boost because the bowls in the E15ET piston are huge (23.5mm)

yea thats sounds bout rite.....if mine is all ready gota 5speeder n retunnled....should a ca18 drop stright in wif a maddat crossmember?

He broke things himself
Not a fault of the components
User error maybe

Hahaha... sorry Michael

I'll rephrase
Boost too much on a stock old engine thats not built properly it will break
Boost a built engine with the right pistons and fuel supply and it should last

Hmmm tell that to 1200rc!

yea cheers....how relieable is it tho

Don't sell the A series short
They last with boost very well

Rarely do they see a failure of any of the factory components
