hey all,
i just bought a 2003 GT 5-speed about a month ago, as i have been converted from the torqueless hondas im used to toying around with. i would of liked to get an 03' cobra or mach1, but the funds were basically not there, and i couldn't pass this deal up. any who, my question is this. i have been reading alot on here, and on other forums, and have came to the conclusion that i definitely want to go forced induction. so far my car has aftermarket clutch, udpulleys, k&n cool air, and steeda short throw. i just ordered the magna-flow magnapack cat-back, and am getting ready to order a catless x-pipe. i plan on buying a kenne bell by next spring, and also some 373's. i was originally going to buy some bbk longtubes as well for my exhaust set-up, but the more i read and how much work they are its really not worth it. what do yall think? on a stock motor with a kenne bell and a upgraded throttle body and exhaust, would headers really be necessary at this point, or could the money and time be spent better elsewhere such as suspension like i originally planned. this is going to be a streetcar, and i wanna take it to the track on the weekends. is there any other supporting mods you all would consider other than suspension? i will be going with the kenne bell 2.1 intercooled by the way.

and what do you all think about the H&R's super sport springs with some blisteins, cc plates, and mm lower and ford racing up control arms??

thanks alot everyone!!

buy forged internals or your gonna have quite the mistake on your hands.

our engines will hold the power, but not for very long. buy some forged internals and itll be BETTER, but not perfect

Welcome to the forums.

Your gonna need forged internals you cant just trow on a 2.1 KB and not do anything else. And why would you put it on without suspension work

And the Long tube headers are a must they will be much better than shortys. Even on a stock motor they are better than Shortys

go to the kb website and read it,you can put a 2.1(9 psi intercooled) on a stock motor with their tune and be just fine,I know I have one and beat on it. don't take anyone's opinion that does not have experience or have owned one. longtubes give you about 2rwhp with a kb,again read their website. They have dyno tested exhaust. anybody that has PROOF to discredit what kb has on their website,Lets see it I would like to see it.

Now I am sure once you go beyond just throwing on a kb on a stock eng exhaust helps, the research I came up with is that shorty's actually help more than longtubes on a kb car. there are a lot of websites you can search for people with kb's and what did or did not work for them. learn from their real life r&d and not speculation or theory

man dont listen to this crap, your engine will handle power just fine as long as you have a good tune and keep it maintaned properly. i would not suggest you run anymore than 9-10 psi and dont go over 450 rwhp, but this guy makes it sound like it you make any power at all, its just going to blow up. well thats not the case. i would also suggest that you get a tune on dyno tune, and not using a simple tuner that gets sent with a preprogrammed tune. every car reacts differntly to the same mods, and do you want to risk hurting something to save a couple hundred bux.

anyways youll be fine as long as you keep it toned down and dont try to make huge power. 9 psi will be fine and you can always build a little bit of safety in the tune by running a tad rich. also your engine as long as you take care of it, will handle the power for a long time, but you must limit your rpm to around 6000 with boost on the stock internals.

on a stock motor with that kb, there is no need for any typoe of headers at all. that kb has the potential to make more power than his motor will hand even without headers. so dont worry about them and spend the money elsewhere. again you do not need fordged internals to run the blower. but you must get a good tune

thanks for all the replies guys, more are welcome. i have been reading on KB's wesite and it doesn't appear that any aftermarket header is worth it. from what their dyno tests show, and what they say. this is very interesting. at 9 psi the kit makes 405 hp, and this was only with aftermarket mid-pipe and cat back. everything else was stock. there is a tone of useful information out there. i just wanted some more personal opinions from here.. thanks

the 405 hp they claim is with a 12.5 a/f and 23 deg of timing. (avail on their fllip chip).the tune for 93 is around 11.1 a/f and timing around 16, realistic hp is around 380rwhp. very nice engineered kit,very complete,just need spark plugs

+1, our engines will hold 400-450 easily. And if its going to be a street car, i recommend that you dont go much higher than 450. If you want it to be fast, you're gonna have to do suspension, with that much hp, its gonna be impossible for ur tires to grip 1st though 2 through some of 3rd... i recommend lowering springs, shocks and struts, upper and lower controll arms

[Drick]

Why do a blower ad make 400 HP without ay suspesion work. You will put 6K i the motor and none in the suspenison. Sure you will have alot of HP but you wont be able to get it to the ground

[limited]

don't forget guages, a wide band,boost and fuel pressure guages.important and expensive part of forced induction thats often not budgeted for.

[limited]

suspension is important for any build,but just a good set of tires goes a long way. The kdw's I have on mine,with just lowering springs hook pretty damn well. I don't have traction issues unless I want them

[35th_Anniversary]

Billstein shocks/struts
H&R ss springs
Urethane spring isolators
Camber caster plates
MM rear lower control arms
Ford racing upper control

He has already posted what his suspension set up will be a couple days ago...

this is the Gospal! i have a 2.6 and had to go heavy duty on the internal stuff but at 9psi you should be OK, but if the motor has a lot of miles on it 100k+ you will start getting blow by somewhat quickly.
