Hey, new to the forum. I have a 91 gt with gt40 heads, 1.6 roller rockers, and a f cam. Have underdrive pulleys and small stuff like that with 24# injectors. Anyone have an idea what intake would work best for me? Over the winter i am upgrading to 30# injectors and twisted wedge heads. Thank you
Im getting twaited wedge heads or something different than my gt40 onesGo pick yourself up an Explorer intake from a local pick n pull for $100 and call it a day. No need to spend money on an aftermarket intake when you're just going to be choking it through a set of GT40 iron heads.
Well, since your mind is set on it. I think it's a very good idea. AFR makes some really sweet heads too.Im getting twaited wedge heads or something different than my gt40 ones
I agree but isnt a procharger like 3500 bucks for these and still need bigger injectors and stuff..and also isnt it better to have better heads for forced induction? CuriosityWell, since your mind is set on it. I think it's a very good idea. AFR makes some really sweet heads too.
Though forced induction is a fun thing to ponder.
GT-40 heads would love a Vortech super charger. After you strip your engine down again to put $1400 TF heads on, $600 intake, $275 accufab TB with egr spacer, $100 ARP bolts, $100 gaskets, $400 for new cam, lifters, locks, springs etc....$300 for new stud mount roller rockers, $80 for new GSS340 fuel pump, $200 for new 30lb injectors (your 24's would be fine though), $300 for new PromM MAF to match your 30# injectors, and other misc stuff will be about $3,700. You will gain probably 70-85 HP with this to net you maybe 300 rwhp which is typical for this combo. You'd benefit from getting a tune to maximize driveability and HP potentialI agree but isnt a procharger like 3500 bucks for these and still need bigger injectors and stuff..and also isnt it better to have better heads for forced induction?

If you're set on staying naturally aspirated and going with aluminum heads then I'll just be quite about going boosted. Ultimately it's up to you what you want, i'm just letting you know another option that probably isn't any more expensive then the road you're already going down.I agree but isnt a procharger like 3500 bucks for these and still need bigger injectors and stuff..and also isnt it better to have better heads for forced induction?

So what would it cost roughly to go vortech?GT-40 heads would love a Vortech super charger.

$3k buys you a Vortech tuner kit, you'll need a bigger fuel pump, MAF, 42# injectors, and a tune as well. This should net you about 350 rwhp easily.

i picked up ~65rwhp (from 265 to 330) going from my gt40p/tfs1/streetheat combo to tw170/tfs2/rpm2. thats n/a. and with a kinda slow cam. the power potential is there if you don't sissy out like most people tend to (amazing how many people put too small of parts on and wonder why they're still slow), and pick the right components (and don't skimp on springs like i did). the newer tw11r's that are out now are even better than the old 170's for not much more $$.I'm going a whole different direction with what I think @Dan duffy should do with his moneySinking money in to Trick Flow heads will net you some HP but not a whole lot since you're already sportin' GT-40 heads. So it's not like you're going from stock to TFS which would be a bigger gain. With nitrous you have to fill the bottle and pray you never get a puddle in your intake runner and go BOOM!
My $.02 is add boost. You already have an OK combo so if I were you and had a few bucks I'd get a Vortech V3 kit. You'll have great driveability and 350'ish rwhp.
Those new roller rockers you have on your GT-40 heads won't transfer over (GT-40 is pedestal vs TFS is stud mount) nor will your pushrods. The money you save from having to buy all gaskets, new ARP head bolts, TFS heads, nitrous, all fluids, you could invest it in to a Vortech kit.
I don't disagree with anything you said however the OP did mention something about this car being a DD I think so I don't believe he should milk any combo to the max potential.i picked up ~65rwhp (from 265 to 330) going from my gt40p/tfs1/streetheat combo to tw170/tfs2/rpm2. thats n/a. and with a kinda slow cam. the power potential is there if you don't sissy out like most people tend to (amazing how many people put too small of parts on and wonder why they're still slow), and pick the right components (and don't skimp on springs like i did). the newer tw11r's that are out now are even better than the old 170's for not much more $$.
the better heads will make even more power with less boost (more cfm) if you end up going that way eventually, though if you do you'll be knocking on the b-breaking door.
Like mentioned before, @84Ttop is the man. He's a Vortech/Paxton dealer and his prices can't be beat from what I've seen.So what would it cost roughly to go vortech?
