if im upgrading the cam i have to upgrade the fuel injectors right? Any suggestions on size? Do i need to upgrade the fuel pump too?

 

You should be fine w/ the stock pieces unless you throw ported heads and long tubes into the mix.

 

check out your other post.

 

injectors support a specific HP level. Nothing else. If you upgrade a cam and that adds 50-100hp you may just want new injectors but it's completely probable that you don't. more details on the car, the cam and the current setup and we can be more helpful.

 

well i have....
shorty headers, x-body off road w/no cats, 75mm throttle body, CAI, upgrading the cam, upgrading coils, and possibly intake manifold...should i upgrade the injectors now?

 

like we said... no. THere's nothing there that's going to make any more power than stock.

 

and dont bother with the coils or intake manifold upgrade ona 2v motor you will gain little and spends LOTS!!! spend your money elsewhere.

 

w00t!

 

so when i upgrade my heads i should upgrade the coils, injectors and intake manifold then?

 

oh yeah, when i get back from iraq im swapping out the shorty headers for long tube...i dont like the shorty ones at all...

 

The problem w/ the manifold and coils is that they are very efficant from the factory. You use to have a single 40,000V coil for all cylinders instead of individual ones for each cylinder so you get the idea on how good they are. However, injectors may need to be upgraded, depending on how much power you are putting out.

 

with all the new parts i was given an estimate of 300-325...thats after the long tubes are installed and the cam. I have other upgrades too though, i mentioned above. But the cam is the biggest upgrade besides the long tube headers and the stlall converter im putting in. im thinking about taking out the 4.10s and putting in 3.73...bad idea or good?

 

leave the 4.10's in. You'll probably fall short of 300rwhp but it should be fairly close. Leave the coils alone. Stock is fine. Stock replacement if you need them only. Injectors as power requires. Until you put in a power adder 24's are more than sufficient.Stock 19's are usually fine.
