Gday all z22sers. corsaZ22se vocky evocarlos Been a while since my old car was written off and ive posted here but the bug to get another Astri Sri is biting.... hard. I will apologise in advance for the long winded nature of this post.
I have my eye on this
https://www.carsales.com.au/dealer/details/Holden-Astra-2001/OAG-AD-16213396/?Cr=0
Took it for a spin today and the good news is no death rattle in site (or earshot rather) AND as far as i can tell it still has its original paint no accident damage whatsoever- rusty in places and underneath the carpet in the boot, front subframe and slam panel - which is odd because of the galvanised body so i suspect water damage sometime during the cars life.. Also noticed the engine was considerably quieter than my old Astra - not sure what to attribute that to - at first i thought it was the metal rocker cover instead of the plastic one my old car had but then i remembered that pre 2002 models have a precat whereas newer cars dont??? Perhaps someone here can enlighten me on that one
The bad news is 2nd gear is awful which myt not be so ( bad see below)
Planned mods are
1. Ported exhaust ports
2. Balance shaft delete
3. 6 Speed conversion
4. ported throttle body
5 de restricted intake
6. Sound deading over the rear wheel arches
7 Astra mk 5 torsion beam rear
8. skimmed head for higher comp ratio
9. remap
The car is to be a daily driver and the objective is to make the car smoother, quieter, faster and use less fuel than than new - im aiming for 170bhp and 6.0l100km fuel consumption on motorway with the engine sitting at about 2500 revs at 66 -70mph. Specifically my questions below are directed to those who have done the above mods
1. whats the m32 box like behind a z22se? I like a shorter shift rather than a longer throw and a smooth quick action, will the m32 do the trick - id have to say the only thing i dont like about mk 4 astras is the first to second shift gear change which is a lot slower than it should be and a bit notchy too
2. Does balance shaft delete and skimmed head improve fuel consumption noticeably?
Any input/comment into any of the above areas would be greatly appreciated.
Cheers
Patrick
