ok my car as of now is the stock 305tbi i want more pep and whatever else there is. i have 500 dollars to spend on some mods but i cant go too crazy into things such as heads/cam. i already have a dynomax catback and a gutted cat. i also have 245 width brand new tires.

 

I would have to say Headers.

 

thats it just headers i was thinking of more than one thing and i want the biggest gain i can get because my car is awefully slow.

 

Headers.


Maybe get some heads off a TPI 305 and get them ported. Or you could invest in a new air cleaner/intake manifold.

 

the biggest bang for the buck is a new set of gears. when i had the 305 in the T.A. i put 3.73 gears in and WOW what a change that made.

 

bah i like gears and all but i dont like them after experience. my cousins car is an 83 crossfire i swapped a 350 into and he has an open diff like me but previous owner put in 3.73 gears and i was driving it last saturday and just tapping the gas spun his tires which actually makes him slower than me since he spins on launch and i dont and he doesnt even have anyother mods except flowmaster catback.

i think im going to get a set of hedmen headers with a y pipe and get an open element intake since dual snorkel flows less and is rediculously priced.

 

Sounds like a good enough plan to me, more air in and out is the whole goal of performance.

 

how are the hedman HED-68481's sound for my car? then do i need a drop base open element intake to fit it under the factory hood and what size filter to use to clear.

 

Thats my settup and it is not loud, but sounds very well.

 

i actually think im gonna go tomorrow and get an open element 14x3 from pepboys probably since i got free gift cards. then ill prob order edelbrocks TES shorty headers and y pipe with the ti tech coating. then i think ill be partially satisfied for now.

 

go for it

 

Get full exhaust

save money

4th gen rear

save money

1.6 rockers

save money for when something goes wrong.

 

4th gen rears will make your tires stick out farther (just for his info if he didn't know) about 1 1/2 in out on either side (a lot in other words).

 

I would avoid the eldelbrock headers, I do believe they are only 1.5" and the collectors are very small. If you're on a budget go with the headman's and their y-pipe. If you want to spend a little more money, or possibly save money have a custom Y-pipe made by an exhaust shop. The Headman Y-pipe goes from 3" and then into a single 2.5" pipe at the cat. It is mandrel bent, but this is still a restriction I would have the shop come off the headers with 2.5" pipe then go down to a 3" or even a 3.5" pipe if you can get it. If you really wanted to make a nice Y-pipe you could stay with 3" pipe off of the collectors and merge them into a single 4" pipe.

 

if i got a rearend id prob stick with thirdgen i really dont want my wheels out farther i dont like the looks of it but i dont want gears YET. how big of a gain do those 1.6 rr get? better than headers and y with an intake?

 

The ONLY thing that will benifit him right now in that is the air cleaner. Keep your money, don't blow it on the TPI heads. The factory intake is not that bad either, especially with a 1" open center spacer on-top of it.

I would look into an EBL, a Moates Burn1 and AT29C256 flash chips. Dialing in your current combo will definately make a difference. I have seen 25 RWHP hide in the stock GM programming on TBI cars/trucks with STOCK engines!

 

Yeah good call. People have seen(and shifty has repeated many times) that 1.6r's can take can take off .2 in the 1/4 and add a mph. Iv'e read every single page on the TBI board(or around it 150-160ish) and it seems that people have had good success with them cause the cam is so crappy.

But I'd do full exhaust first no matter what your'e doing. Maybe some 2055's with either a test pipe or high flow TPI cat, and a nice 3" catback.

From what I understand Exhaust and tuning will get you GOOD progress on a stock lo3.

 

how much is it for all the burning equiptment?

 

It's a little over 200 for the equipment and misc stuff like chips(cheaper if bought used). You do need a laptop, but it is where most of your gains will come from.

If I end up buying a camaro I'll get into chip tuning so it'd be nice to see someone such as yourself try to take on chip tuning. I think the gains and benefits of chip tuning is undoubtable, it's just that it,(from what I understand) can be difficult to learn.

If you're up for the task I think chip tuning would be the most economical mod you can do.

I'll shut up now.

 

would the chip burning also work for the 83 crossfire? im only asking cause then id split the cost with my cousin cause hell want it too.

 

If you swap over to the later style TBI ECM you can.

 

could a tbi ecm run a crossfire injection system? i wouldnt think so but i dont know too much about it.
