Honestly with a non turbo engine I would focus on making it handle better. Springs, coilers, swaybars etc.

these threads should be deleted how many do we need its beyond a joke

We should make a NA upgrade starter pack.. with air filters and headers.. Sell them and advise of the 0% power gains..

Listen to these boys because even i was a little ignorant, cai, exhaust and head work will only result in about a 10kw gain probably even less, i'm working in something to give n/a's abit of an edge for not as much $$$ but thats abit far from now >.<

Complete forged rotating assembley, high compression pistons 12-13:1, ported heads, oversize valves, uprated springs retainers Camshafts with lots of lift and duration. Adjustible cam wheels, Custom extractors into 2.5" exhaust, Bosch 044 fuel pump, 550cc injectors. Autronic SM4 computer. Tuned on E85 with a 150hp wet nitrous hit.

Should do a 12 or 13 second 1/4mile time. Be an absolute pig to drive, you would have to rev it out to 8500-9000rpm to get decent numbers to at least keep up with mods modified factory turbo cars..spent 10-15k and maybe get a fast fours feature if you change your name to FLAWLS

hahahahaha

That post should be sticky'd and labelled "NA guide to unreliable and expensive power."

Listen to that man, he speaks truth!

Best engine upgrade to an NA IS an engine upgrade.

Or just live with the NA until you sell and buy a turbo.

Can't push shit up a hill...

When my brother was on his Ps, he n my uncle (engine builder/mechanic) did up a (stock 100kw flywheel) NA 1.8 4G93P with regrinded cams, forged oversized pistons, raised compression to 12:1, lightweight flywheel & pulleys, played with AFR, custom extractors into 2.25" exhaust and to managed to get 100kw @ wheels n do mid-low 14s with 2 sec 60ft but only after smashing 2 diffs n 3 driveshafts I the process... After that he realised its not gonna get any quicker n decided to just build a turbo track car...

Everything was done free through favours and being a guinea pig as no1 in Oz did it to a proton/Mitsubishi 4G93P but would have cost at least 5k to do...


End result was quick off the mark due to light weight bcoz racecar strippage but had no top end to keep it going... On the street it would give all the Honda boys a good scare n a few turbos

If u wanna blow 5-10k by all means but that is a lot $$$ that can be saved for a turbo conversion...

Do once n do it right!

Hows this....

We have a FG XR6 as a work ute (Im sure I've told this story before) that we also use as a play thing.

I had it on the dyno running some numbers with the bonnet down and the dyno fan on (car is bog stock).

Opened the bonnet, removed the air filter element and lifted the air filter intake so it would take cold air directly from the dyno fan and it made an extra.....wait for it....



..........that's right..........







.......2Kw.


My VS makes an extra 1.5Kw if I fashion a cold air scoop out of cardboard.
