1Y power increase estimate and other questions too

[blunt]

Right just seen someone say the 1Y and AAZ are infact the same engine, oil squirters and all, just the LDA and manifolds are different, is that true?

right so far im thinking that ive got the original 64bhp back  :lol:  had to remove the cat and the EGR system completly, it was jammed open so dumping all the lovely hot and used exhaust gasses back into the intake  :evil:   what can be advisable to get some more ponies unleasehd without messing with the pump internals? within reason that is

whats the most restrictive part of the 1Y manifolds anyway, exhaust or intake

Neither is restrictive. You just need turbo for it

na, no turbos, kinda liked the idea of a eaton m45 but i dont quite know how to get it to fit properly yet, need a design in my head but cant come up with one without making brackets for water pump, power steering pump and supercharger aswelll.
