Jeremy's interpritation of a nice 3rd gen

1. Straight body, no rust at all.

2. Engine that runs strong, and throws no codes. Doesnt leak any fluids

3. Tranny, and rear end seem to be in good condition

4. Paint, it can be a little faded, cause its an old car, but it has to BE ALL THERE. No chips, or missing paint.

5. Interior, the same it can be obvisoly not new, but no extensive tearing or cracks in the dash.

6. SOund system doesnt have to be top of the line but it needs to work

7. T-tops are gonna leak, but I would rather not get monsooned everytime it rains since I live in Florida.

8. Any power acessories the car has needs to function, and while not a must, I would pay an extra $300 for cold AC in a heartbeat. Its damn hot down here 10 months out of the year.

I think if one is patient you can get that for upper 3k or lower 4 pretty easily. At least down here you can anyway.

The 305 TBI is not just the higher end RS motor, it is actually the base IROC motor as well

locosteelersfan

Are you sure about that. I think all IROC's have TPI's..
Is yours not a LB9?

DarthIROC

I know you can get some carbed LG4 IROCs but Ive never seen one with a TBI motor in it

Dave89IROC

nope, it's the base 305 TBI (LO3), all I have seen is that it is the base motor 88-90, it replaced the carb motor(LG4) as the base, rarer, due to the fact that most original buyers opted for the higher output TPI, also, I think that most, if not all, of the option packages came with the TPI


91-92, it only came in the base firebird and the RS

I have seen Formulas from 91-92 with the LO3 as well...

locosteelersfan

But are there T/A's?

kiztope

TA's with the LO3? Honestly dont think so.
I really have never seen a Z with an LO3 either...

I know your mainly intersted in the L98 but I wouldnt count the LB9 out if you came across a good deal. I got mine(car in the sig) w/ 88k for $3500. w/ minor mods I had mine into the 14's.

Bone Stock - 15.6
Flowmasters 40 series muffler - 15.3
tune up Accel cap, rotor, 8.8mm wires, NGK plugs, Nitto's NT555R, removal of some belts - 14.9
Homemade ram air and bumped the timing from 6 to 10- I'll let you know this weekend.

As you can see, if you get one that is unmolested, and w/ low mileage, they can easily beat some L98's.

Rage, a 7/10's increase equals about
70rwhp. Think you may just be getting
more use to the car I mean I wish I could
buy a muffler and plugs to get that.
I'm not being a smarta$$ but those mods
wouldn't get you anything near that type
of gain.

Rage

Never really thought about that, but maybe your right. But, when I bought the car it had been setting for two years, and it really needed a tune up, but I just took it to the track and came up w/ 15.6, so just a tune up was badly needed and if it would have had a proper tune up to start w/, it probably would have done better to start with. But I dont know dude, Tires can get you 1 or 2 tenths, muffler can get you 1 or 2 tenths, ram air is another 1 or 2 tenths, removal of belts and a timing adjustment will get you 1 tenth or so, I dont know, It seems right to me, but maybe your right.

locosteelersfan

You also seem to be "stacking" the mods.
Meaning you can't just add up all the advertised
gains and say I now have this or I now can run
this.. I doesn't work that way and No ram air
is going to give you 20 hp or 2 tenths. The ram air systems
really don't do much under 100mph and you
aren't even trapping that.

You are right about the ram air but if he is using the design that I think he is then it would work very good for CAI, considering

1. the engine is getting air from outside the car, not the air in the engine bay.

2. the air boxes on 3rd gens are very restrictive and by cutting the bottoms of them off relieves a good deal of this restriction.

doug791

where to start where to start. Youre right to a degree but the point youre making just goes to prove him more right. The power increase you get from a "Ram air" or glorified CAI is exponential. With his current setup he may get a 20 hp gain with the system. Once he puts a new intake on it may turn into a 35 hp compared to the same setup with factory induction. So the more he tunes his car, the greater the gain will be.

You also said ram air doesnt do much under 100mph which is horribly wrong. You cant ram air at automobile speeds it doesnt happen. What you end up with is a very good cai system that will help you all through your power band.
