Hey, i have a non turbo 1994 SW20 Bathurst mr2. I was wondering if there is anything i can do to improve the power of the car??

basics as follows in principle.
1: hiflow K&N replacment panel filter
2: mandrel bent extractors into a hiflow cat and 2.25-2.5in exh with free flowing mufflers
3: camshafts starting from 264 dur hilift (gen3 na already have a 250dur IN cam) 
4: ECU upgrade to get the most out of cam upgrade, stock ecu should cope with 264's but prob not with 272-300dur cams.
5: rebuild engine with high comp pistons, port work and increase valve sizes.

Thanks a lot on the tips, I ran 15.3 at eastern creek, Is that normal for a standard mr2.

And be prepared to bend over and dish out over $7000 lol. It all adds up :/

15.3 sounds quick for an N/A, good work.
hard to get much more power out of an N/A, unless you're really passionate :P

i got 15.8 before lsd and rebuild. 15.3 is very good.

Ive got an 1995 bathurst n/a and have done a few mods heres a few things i recommend
 
Aries forge pistons
Stage 3 cams
Yamaha cylinder head
Port and polish
Ems stinger computer
Ferrari vales
After market air filter  
 
These are just a few things i have in my car and it goes insane :) ..
 

I always say it, but when there's a turbo engine that bolts directly in I don't see the point of working an NA motor. By the time you've got a full exhaust, decent intake, cams etc you could just buy a 3SGTE and still have more power.
If you're under restrictions of some sort, then put your money towards suspension. Springs, shocks, swaybar, bushes and tyres. I'd much rather a car with great suspension than an extra 40kw.

^what he said
Whiteline front swaybar made a HUGE difference to mine. Negated the need for overly stiff coilovers.
