03 GT Single Turbo Question

[TransAxle]

Okay just saying, that you made a FULL custom turbo kit, on a mildly modded motor....i am curious but if you alreayd have full length headers on the car would you have to change them or would they work with a custom kit? Also i see alot of sites that say you have to have a tubular k-member kit on the car along with caster camber plates? Is that neccisary or just a sales pitch. I KNOW it can help but i am asking is it REQURIED?

thanks

[SpectorV]

your headers will go bye bye they simply wont work with a turbo kit, it takes custom ones in every mustang application ive seen.

The reason they say you need a K member is it makes for more room, ive seen some that dont require this, some do... its a choice in how they make the kit.

[TransAxle]

okay cool thats what i figured, i alreayd have the turbo back custom exhaust thought out and everything just checking to make sure i dont need the k-members!

Well make sure you post pics / updates as you go.

You can take the stock manifolds and turn them around backwards to use as headers.They work trust me i've tried it

[rydog]

mine are stock headers flipped around and the collectors cut of and a a 3bolt flange welded on

Ummm what? Better power? I would like to see the numbers if I may... Any kit can be faster than another, but do it with the same boost and same turbo and same motor with the same mods on the same dyno... I think you might just end up not making the same power.....


Another thing though, that kit comes with EVERYTHING save for a tune. Full stainless, tubular setup, the works.....

Yupppers, my boss did the same with his. Just got some FRPP headers and turned them around.

already now about the headers! also my kti will have the look upa show engine, with a shit load of power to back it up! also this comes with a two stage tune, one for low boost and the other for higher boost! using a gt40 turbo i believe we decided on! but the numbers where looking at right now is around 525rwhp with around hopefully 600tqr is what where hoping for the tqr!

but i will hopefully have it done before october 1st is my deadline so hopefully starting around mid september...right now just getting all the parts and getting everything ready for my car to go down and get it all done! once it starts i will start a thread for the progress of it!

What kind of transmission are you going to use and have you replaced your axles and diff to handle the power?


And I'm really not trying to be an ass at all, but you did avoid my question about how is it going to make more power?

Can't wait to see some pics of the buildup in the new thread!!!

the hellion kit is only rated for around 450hp on the stock system! but the system is good up to 850! my kit will be cheaper look the same and be more effect for less money!

also the rear end will be rebuilt prior to this to make sure it can handle it! the axles will hold the power just fine! a friend has a 02 gt, mild built motor witha 2.8 big bore KB on it and still has stock axles on it! the transmission will also be rebuilt with a better flywheel and clutch prior to this! unless i can find a good t-56 tranny someone wants to get ride of for next to nothing!

Several things.. If your buddies car ever hooks, those axles will snap.

The flywheel and clutch are not a part of the transmission. I'd recommend a TKO500 or 600

The hellion kit is rated at that because of the stock fuel system. If your car is still on the stock fuel system, it won't be able to make any more power than the hellion kit......

lol 500rwhp minimum is all i am gunning for! but most likely it will take a 255 fuel pump, probably up to 39lb injectors and get some better fuel rails!

but naw man you would be surprised at how much abbuse the stock axles can take! hes dd his on 10.5 rimes with 315 nitto 555r's he hooks real well!

also most likely i will jsut rebuild the hell out of the stock tranny becuase my brother has a tko500 with alum driveshaft in his and its a pain in the ass to get those trannys to install on 99-04 gt's. Need custom bellhousings and custom tranny mounts new shift and all theys other parts gets to be quite expensive. So i will probably jsut settle for stronger clutch and flywheel with a rebuilt stock tranny!

I did a quick skim and didn't see it so forgive me if I missed it but are you planning on doing this all with a stock bottom end?? I can see maybe not uprgrading the rear because the power isn't there instantly off the line like with a fully built NA car or even an SC'd car, but there is always the possibility of a snap.

BUT

There is no way you will be able to do this with a 100% stock motor. A stock 4.6 cannot take as much pressure as a stock 3.8. I believe the current average for the 3.8 is 10, and for the 4.6 is somewhere around 8 and 8 psi will not put you anywhere near 500rwhp. N2o on the other hand is a different story, a stock 4.6 can take a much higher shot than a 3.8. Again, forgive me if I missed your engine mod list, but if you don't already have one, you will need it.

[TransAxle]

lol the motor is not stock it already puts about 260/290 at the ground...which isnt much but trust me the 8psi is going to be dd for race time it will be between 12-14 and this is with a stock bottom end!

Higher octane fuel for race time maybe?
