Save the forced induction . Thinking about doing LTs,throttle bottle, and plenum. Is it worth it.

TB and plenum won't net you much.

LT's (depending on the rest of the exhaust) could get you 15-20rwhp......but would cost about $800-$900 (maybe more) including labor.

So, you would spend about $1200-$1300+/- for about 25rwhp.

He could save some money by doing it himself. What about suspension mods, or are you interested in gaining HP?

I hear LT's are a major pain in the ass to install. Most people end up dropping the K member.

Thanks guys, I could do the labor myself . I did my own gear install ( I'm a mechanic by trade )
Basically the only thing on a car I would be scared to get into would be an automatic tranny. I was thinking the long tubes would be more of a supporting mod for a vortech kit down the road. Currently I have an offload x pipe to some weld in flows. For suspension I have cj pony parts 2 inch springs, bbk caster camber plates,and mm full length subframe connectors. Believe it or not the car hooks pretty good on the nitto 555s. So I don't really know if I wanna do more suspension parts at this time . I'm open to suggestions ! I thought the TB and plenum might be a waste, but they are just so easy thought I might try. Maybe do headers and cams instead ? I don't want to spray it at this time because if I got every thing I wanted for a nitrous set up , I would like about 1500 doing a vortech kit ( kit tune bottle heater remote bottle heater ect )

Longtubes would compliment a vortech greatly, also longtubes are worth every blood sweat tear and penny, they give the car such a grunt definetly a must even to a stock car

I am interested in this also. What brands LT's work best? I was just looking at macs. My next question is what about clearance? I have read if your lowered they hit. My prochamber hits now lightly every now and then. I did help a guy a couple years ago put on a set of equal shorties. It was a pita! Is there a write up on long tube install anywhere? I am also a mechanic. but on construction equipment. I will be doing this on jack stands also. My idea is I need to replace my transmission soon. So I figured while it was up, it would be a good time.

MAC is u at the top. I run a full MAC setup (LT's, mid-pipe, catback) and couldn't be happier. I am lowered almost 2" and clearence is a concern. I've had th LT's for long enough that I am able to judge whether I will clear or not just by looking. You learn to take speed bumps VERY slowly (and at an angle if you can). Honestly, clearance isn't a problem anymore. Im not sure if there is a write-up anymore, but an LT install is pretty straight-forward and easy......it's just a complete pain in the arse! I did mine with floor jacks, an engine brace, and dropping the K-member (easiest route).

Thanks! We are supposed to close on our house mid July, then I will finally have my garage. Sounds like I will make a go at this. Now I am preety sure I have read that Lts need to be removed to pull your trans, but not all need to. Do the Mac's?

I didnt notice anything with plenum and TB. Skip that IMO.

Thanks I was thinking I would be better off with out for now. I want macs but the ceramic pacesetters are very tempting. I am thinking of giving them a try.

Macs do not have to be removed is my understanding. Not sure about pacesetters. ( I've had them on ls1s, (fit great, buy the way I've also heard horror stories on gts). I just want my LTs to fit right the first time with little or no mods to k member, floor pans, or stearingshaft.

My friend got the BBK 78mm and he swears up and down that it made a big improvement on his GT, I guess we will find out at the track though if it helped... I have read that the 78mm is a little overkill for a Mustang with stock heads and cams though.
