Hey what's up everybody. I need some feed back on the simple bolt on upgrades I will be doing this next week. I have a 1985 RX7 with a 12a. I am going to be throwing on a couple of cheap simple power bolt ons. I will be swapping the exhaust to a Racing beat street header feeding into a stock cat, then 2 inch piping into a cheap azz generic twin tip straight thruogh muffler. I will also be swapping the stock air intake can( the blue one under the hood) to a racing beat power pulse intake. I will also be removing the air pump and instaling a block off plate on the intake manifold. The motor is a stock 12a, it's a new motor, with a freshly rebuilt stock Nikki carb. The car runs great, perfect dialy driver, I am just s little bored with it so here come the cheap upgrades. Now my question is should I retune my carb at all???
Will I be hitting a lean condition at top end or to rich at low end. I don't drive the hell out of my car often but somedays I just have to. On the days I drive hard I rev it to about 8k+ rpm's. Pretty high I know but it still makes power even without having a port job. The carb as it is is running slightly richer than it needs to. I figure if I have to I can drill out the stock fuel jet holes and throw in Holley fuel jets if I need a lot of re tuning. We do the holley fuel jet swap all the time on our streetport cars but I have never run a stock motor before. Tell me if there's anything you all think I should expect. Thanx a whole bunch

wow.. im not an expert in these things but have been an fb owner for more than 2 years i think..
um.. dont over spend on mods u may not like.. remeber gas prices are going up and i think yur main priority irght now is to make it run as reliable and as good as possible.. rebuilding the carb is an excellent idea.. as for the motor? how many Ks has it done?

if u are bored with it,... work on the body.. improve it.. make it shine.. then the interior.. make it nice and comy.. dont over spend on the engine as u will end up in a money pitt.. trust me..

dont over spend.. just make it run beautiful.. orginal.. oh spend money on suspension and steering.. oh oh.. and WHEELS BABY!

then if u really have some more cash to spend.. buy a security system.. like an alarm it works good too when yur locking and unlocking yur fb since it is central locking..

also restore the AC and heater.. i dont care wat people say.. its better to have it..

oh.. sound system..


dont spend too muhc on buying a better engine for it..

like a 13b.. or a 20b..

make it as original as possible but reliable and mint..

trust me its also a good investment as it will have a better re-sale value.. specially with these old cars..


unlike lets say.. a supra.. u do that up.. u can sell it for more since its a fairly new car.. when people buy old cars they want it as original and untouched yet reliable and engine rebuilt..

sorry for the double post.. accident on the enter button
