What can I do next?
 

Well I've gone auttocrossing about three times this season and have imprived my time consistantly. Yesterday I was aroung 1 second off the leader. I want to see what mod I can do excluding serious motor work and for less than 400.00 the mod should give low end power enough to take a second off my time. Below is the list of what is already done to my RX check it out and let me know if anyone has any ideas... Thanks..:stickpoke


RB Headers
High Flow Cat
Cat back W/custom suppertrapps to add backpressure (Belive it or not I had a friend time me with and without them and they actualy help)
Flex a Lite Black magic radiator fan
Underdrive pully
Apex I Intake
Tokico 5 Way
Tokick Springs
Mazdatrix Strut bar (the one that connects to the firewall)
Mazdatrix engine torque brace
Corabu Racing seats (make it feel faster:spank: )
Interior is stripped no radio nothing( who knows why? I think it makes it look moe like a race car:sperm: )

Get a set of racing slicks...

Tires are a good idea!!

Racing school, if you haven't already.

If you are autocrossing, Low end torque should not be an issue. You should be in a gear (2nd) at high revs for 99% of the time anyway!!

2nd gear and high reves is where i'm at that's not low end but i figures if i had more low end off the line then i'd shave something off my time. As far as slicks go should i be increasing my rim size as well, Im on stock 15's in my 91 rex , and which slicks are best

Try a set of 4.30 final gears. Cost might be a bit more than $400, but will help with accelleration. You can find more info here: http://www.rx7.com/cgi-local/2catalog.cgi?cat=2&part=6

Set of race tires, 205/50/15 and a set of shocks and springs

SUPERCHARGED REX
 

is it possible to put the gears into an automatic? is it a noticable change or minimal? Thanks.
