ok my friend Jay has a 91 camaro RS 305 TBI auto

his current mods are headman headers true dual 3 inch exhaust no cats to dual glaspacks and dumps before rear axle

373 posi

underdrive pulleys

smog pump removed

drop base air cleaner

high performance igniton wires and plugs

he stil has the stock tranny with no mods to it

and everything else is like completely stock

he was asking me what cheap mods he can do to it to make it just a little faster but not nothing to where it is a hot rod

i told him throw a shift kit,stall converter,corvette servo (i have no idea what this does, or if it really really help any, i just know i had one put in mine)

maybe a chip and a dyno tuning

he doesnt want to have any forced induction or nitrous so that is out of the question and he wants to try to avoid new heads,cam,intake,throttle body


any suggestions, i really think tuning that tranny would help some

he wants to get the car to about 9 second flat 1/8 mile time ish maybe a little lower and he is now at a 9.8 so throw out some suggestions please and thanks

 

with the 305 .. 9 flat in the 1/8th is out of the question without a power adder.

 

cam an stall

 

spray the piss out of it

 

The 305 TBI system is hard to work with because they don't make a lot of stuff for it. A stall converter and some better tires will probably do the trick for what he wants though. If not, theres not much else you can do without going carbed or TPI.

 

2200 stall

Eddlebrock makes a TBI intake manifold that is comparable to a good 4Bbl manifold.

Get a small cam 210/215 .490 range, there are a bunch that can be had for less than $200.

150 HP N20 plate system. The TBI system should allow for the placement of a NOS Sniper plate.

That could get your freind into the high 12s. But realisticaly a 350 swap is his best bet.

 

Spray it 'til it pops, then grab yourself a 350

 

+1

 

For the most power increase I would suggest the radiator cap swap mod.

 

The car is on nitto dr's.

So realistically it's 40-60rwhp away from his goal if he gets a bigger stall.

Tell jay to quit fucking around and get a 350.
