turbo 3.8 v6 or swap to (turbo??) 4v dohc 4.6 v8???

Ok, so I'm looking to make 600-ish hp. Is it cheaper to do the 4v dohc 4.6 v8 swap or shuld I just work on my v6 and turbo it. Also which wuld be more reliable at that power range? Thank you.

if you're still wanting 600 then the 4v is the better option...

Ya I am. I want to be competative in drags as well as dominate in the corner races. Not all boys will put down money on corner races. But most in my area r just itchin to drag race (even though its not my fave style).

there's a large difference in how the two types of competition are setup. building for one will hurt the overall performance in the other...the middle ground setups don't really dominate in either but just perform ok

Oh ok. I didn't realize it wuld make that much difference. So if I build my car for as u put "corner carving" and I have say the 600-ish hp I want and I drag race a guy. If he's got 500-ish he wuld whip me?

yes if his setup is built for drag...and 600 is a lot for corners...right now my sixxer can keep up with my friend '01 500 hp cobra on roads like hte dragons tail all because of suspension differences and how we're set up. heck i'll leave him behind if i start out in front (its a double yellow so no passing)

hp can mean nothing if it's not being used to the fullest on the ground

Well first off, let's say this...
The driver mod is the most important.
Secondly the suspension for dragging and corner carving are different, in a corner carving situation, the better car would be the lighter 3.8L mustang or v6 for that matter. We have a very good base for a cornering machine with the v6, you don't need power to corner, unless u have lots of straight aways...

By driver mod u mean basically the driver that's best at the kind of racing that's happening, correct?

it's as intense as it gets...after each new suspension mod i drive 3 1/2 hours to run this road all day long. and each time i get faster and faster on it.

Lol good.
Well... Let me share..
For a fully built 4.2L Stroker
8.8 rear end
Tranny upgrade
Stall
Tuning
And blower of choice(5k)
I was looking at near a 10-12k build... That would put me near 550 rwhp maxed out...

With a 4.6L DOHC swap... Your looking at an expensive engine 3-5k alone, look into about 1k for the tranny, then the time to swap or... Have a shop swap, plus the IRS or solid 8.8... The build could be near 7-8k then power adder and supporting mods to get to 600 HP would also run you another 3-4k so in the end... Both end up pretty expensive... And I know... I hate hearing this term myself...

"Just buy true car with the right engine"
Or
"Just but a v8"

But in all honesty it's true... Very very true...
The v8 platform is cheaper to mod because it's more acceptable to mods, more parts available and not as much custom work(which jacks the price up being custom)

If you do this v8 swap you have to tell your insurance you now have the v8 engine or you could be in trouble for insurance fraud if they ever find out, it's a ****ing hassle...

I say enjoy the v6, maybe drop a few grand into her, make her QUICK but not FAST, and make her a cornering machine...

But do what you want.
Those are my opinions.

Just practice makes perfect pretty much. Launching isnt easy but neither is cornering.
Early apex turn late apex turns ETC...

This a track or city/county road? Also u shuld have stock about 205hp@3g/230-ish LB@4g. That's whag my research has showed anyway. U have better ports than my car, better heads, etc. Atm I'm making 145hp@3g/215lb@4g stock.

when i sold my GT for my sixxer i thought i'd regret it, but i've enjoyed the car..yes the power loss was a huge hit to me when it came to going to the 1/4 at Beech Bend, but i feel it shifts weight better in the corners which is what i enjoy more

you're talking crank horse power...in the modding world we use rear wheel hp...

if you're sitting at 145hp stock then you're around 110-120 rwhp stock depending on your transmission

btw my '04 is rated at 190ish stock crank

as for where that is..it's a public road between TN and NC...however it has become basically a free road course lol. just remember the cliff sides have no guard rails so if you're car cant handle it and skids you will go off. i've seen it before

an m90 swap would be a good swap for you...would give you a bit more kick and a decent street car. got any pics of your car as is?

Re: turbo 3.8 v6 or swap to (turbo??) 4v dohc 4.6 v8???

sounds good...if you want to make the car handle i can really help there lol..and usually do it for a budget

let me grab some pics of some things to look into

---------- Post added at 02:02 AM ---------- Previous post was at 01:51 AM ----------

here's some cheap ways to really improve your car

-used rear sway bar from a 94-04 GT


-SS brake lines (i got my Goodridge Gstop lines from Mossmuscle.com)


-rear shock tower brace made from spare tubing (i used a used s197 panhard bar with a bit of modding)


-you can also cut your stock springs to give yourself a lower center of gravity...oem springs shift weight nicely so it's a great mod
-get a used strut tower brace off of a 94-95 GT
-full length sub frame connectors are great too..AM has them on sell right now
-also when doing SS lines i reccomend swapping to Hawk ceramic pads all the way around and all new brake fluid...in fact upgrading to 5.1 fluid is a good move if this car will see heavy braking action

and then just have some fun hitting the corners

Pic of drivers door happened while I had the car. A woman backed out of my parents drive way and hit it when it was parked across the street. Hood pic buddy broke a pice of fiberglass off and hood blew off going down the interstate. The previous owner b4 me hit a deer (doing bout 90 we figure from the damage). It hit right drivers side. Destroyed bumper,fenders, there's a hole in the windahield from its antler, and as u can see if flipped off and smashed the passenger door in. Also he spray foamed the drivers side headlight in. Idiot... I'm finding out abuse he did to the cae every day I gotta fix something. (Trans chipped drom jumping. Shocks broken, etc)

this is not the car to ever see 600 hp i hate to say it..something tells me it's got enough damage in it that it's gonna twist in half under that much power

before you build the car i'd fix the outside and go from there.

Already doing that. I have a new hood on it and am shopping junk yards finding the body parts I need. I had my cousin who has been refurbishing cars for 40+yrs look at my car and I had him check to see if there was any chassi or body damage that wuld hinder handling and power b4 I even put 100 in it. He told me the k-member (I think) got tweaked slightly from the deer but other than that everything is solid and for me to bring it by when its time to paint.

well if you decide to get a new k member (which you're gonna want if you decide to go with that much power) i'd look into a tubular k member...it was a pita install on my friends car and getting his coilovers back in check took a while too, but he was happy with it in the end

Oh ok. Ya I've been looking at suspension mods off of american muscle.com and looking at the magazine. Also the high hp wont be started until I have all suspension done, body back to stock, and I want that irs in. That irs is an 8:8 rear right or does that have anything to do with each other? Also I was told the best gears I want r 3:55.

i don't think you can fit an IRS correctly into your body...not 100% on that though. i know there is an axle length difference between and sn95 and new edge...which is one of the reasons why when a 99-04 guy looks for an 8.8 they tend to stay away from sn95 GTs unless they run a spacer to widen it out.

Then ill either stay with my rear suspension. What does it entail making ur car a 8:8 instead of a 7:5? I found a kit to do it for $75. Also if I'm wanting a corner car what gears do I want?

You'll need to swap the rear end. The 8.8 gears won't fit in a 7.5 rear end or everyone would be doing the kits

as long as it's out of a 94-98 it's a straight swap...if you get one out of a 99-04 you'll have to swap axles as well or your tires are gonna sit out about an inch further..not bad with stock wheels, but when you add on wider tires and wheels that can me it'll sit out of the wheel well.

you could also just run a tlok and gears in your own car's current rear. im sure the rebuilding aspect would do wonders on that car
