Worth it or Not?

[gwiedner]

So I have all the mods that are in my signature....basically all bolt ons...I have a 75mm throttle body and I wanted to upgrade my stock MAF and injectors then get it tuned but will it even be worth it or should I just keep my current set up with the stock MAF and 19lb injectors? If a tune is recommended would I have any problems with smog other than having an offroad x pipe which I switch back to factory for smog every two years?

I'd say the TB is overkill, but probably won't hurt anything, so I guess use it as you already have it and it'll be there to support future upgrades. Stock injectors are good for over 300 hp, so there's really no need to upgrade with your setup. As far as the MAF, you might consider getting a '94-95 70mm stock unit with an adapter or just cut off the flange like I did; you can get these MAFs for cheap on ebay, mine was like $40 shipped, and I think I just saw a 70mm '93 cobra MAF for buy-it-now for $30 (and it's calibrated for 19 lb. injectors, supposedly). As far as the tune goes, I don't know if you really need it right now (though it couldn't hurt, but they aren't cheap), in fact I'm wondering if I should tune my car after my h/c/i swap or just wait 'til I get better heads.

Hope this helps.

70mm '93 cobra MAF for buy-it-now for $30 (and it's calibrated for 19 lb. injectors, supposedly).

'93 cobras had 24lb injectors.

not gonna do you any good, and id watch out buying used electronics...

wait till you upgrade the heads and do the injectors at that time. As far as a tune goes, i would just play with the timing and fuel pressure.

thanks for the help guys since the gains seem like they would only be marginal Ill probably wait and put thatmoney toward something else

Yeah I know, but suppsedly this one is calibrated for 19lb.ers; however I've heard that the cobra MAFs can go either way depending on which computer you're using (or of course if you reprogram the EEC).

Come to think of it by the time you drop all that money on injectors and a tune, you could probably get some decent gt40 heads (of course if they're "P" heads you'd need headers too); I saw someone I think on the corral selling BNIB assembled gt40 heads for $400 each, don't remember if they were P heads or not.
