Just been doing some research. Looks like the 1st gen pulls 93kw stock.

Power Output (EFI) 93 kW @ 4800 rpm, 205 Nm @ 2400 rpm

after 17 odd years, surely this would drop a little bit.

Just wondering what I could expect after upgrading to:
M9 Heads
Extractors
RamPod Filter

thanks.

Also, I was going to do the bigger injector mod, but was told that all its going to do ius use more fuel and have no increase in power.
This was told to me by the RPW team and Various wreckers. What do you all reckon?

I want to hit some high KW for a 1st gen... cant turbo tho cause got nowhere near enough cash and thats a no-no for p platers.

thanks every1

i was bored one day and was searching thru the forums and i saw some1 say they had about 60odd kw with a webber on it. i was surprised. thought it would of been more. so i wouldnt think they would have much these days

Webber is only possible on Carby 1st Gens. Its much harder to mod the EFI 1st Gen, and Robbins, yours is EFI buddy, so dont even look at carby mods.

mine was just an example on how much they lose over the years

Not a huge Tech head on the 4cyl's or anything but with those mods you will see very little gain.
Tehy will all help, but probably the best thing you could do would be a manual conversion (cause the auto soaks up what power is there) and even installing a piggyback ECU and having it tuned will yield awesome results

Be sure to take it to the 1/4 mile for a test and tune!:bowrofl: :nuts:

Adding a piggyback or standalone ECU will do bugger all for you without proper supporting modifications. If you're just running standard gear and you put a new ECU in, you won't see any gain.

You only get out of an engine what you put in, so if you add extractors, you won't see much gain unless you free up restriction on the intake side of things. Things like cams and valve porting come into play here too, the better the flow, the more efficient the input / output of gasses is from the combustion chamber.

All a standalone or piggyback ECU really does is command the engine to do things, which is why you'll see gains if you have extensive modifications, because your stock ECU only delivers a stock timing map, stock fuel map etc etc.

You may find that your stock ECU has leaking capacitors too, it happened with my TR's ECU, so it went into limp mode (hence 20 second quarter mile time). As others have said, convert your car to manual, the auto sucks. A lot.

oh snap haha was half right the other day cos peak torque is at 2400 rpm (acceleration which counts for more than power seeing as the 1st gens don't have that long of legs, well not lots of top end power anyway).

yea next time i will be fully right hehe. the only bit i was wrong about was the power quote but the torque comment was spot on. so like i said no real reason to go over 3000 rpm cos ur not actully getting there faster (torque being ur acceleration). like putting on a k+n filter and saying u can feel the power difference when in fact it's just a placebo (sp?). anyway who cares i supose now i'll go back to my corner:D

well all im saying is that over 3000rpm i can still feel that its got more and im sure theres plenty of first genners that agree.
and if you dont believe me do a 0-100 changing at 3grand, then do another 1 changing about about 5... see which is faster.

I agree, torque and power are the same thing ( kind of ) you can't just say drive with the torque because the 2 are very closely related. Shifting at around 4-4.5 would be best as the astron has nothing over 4k.

if the motor is old rebuild the bottem end rings etc will see more gains from that than any mod, stuff like cai etc on stock internals wont do anything massive extractors tend to give a little more torque down low dumping in more fuel doesnt mean more power. with my mods i still use the stock injectors

do you know what the cost of replacing the bottom end rings is? how old an engine we talkin, cause i have around 230,000kms on mine. maybe i should work on rebuilding parts of the engine b4 things like CAI and extractors? whats a rebuild cost (around)?

Ring up some engine rebuild places and find out mate. best way to go about it.
