Hey gang, I’ve decided I’m going to tackle this embarrassing smoking issue i have when i start the car. The engine was completely overhauled about 2,000 miles ago, and it’s done it ever since. I wanted to wait to see if it went away but it’s obvious it’s not going to. I don’t want to say who...

For one of this winters maintenance projects I’d like to replace my radiator on my 03 Cobra. Any suggestions on which one to purchase? I’m looking at a Fluidyne on Lethal Performance but wanted to see what you guys and gals suggest. Thanks Sent from my iPhone using the svtperformance.com...

After swapping out spark plugs for the season I’m pretty sure i found my smoking on startup reason. My #5 cylinder valve stem seals are bad. Any way to replace without pulling the motor and removing the cylinder head? It’s the cylinder at the very front by the power steering reservoir on driver...

Hey gang. I recently upgraded my blower to a KB 2.2 from my ported Eaton , also i had my Tremec T56 overhauled and 26 spline installed while i had it out which means i also picked up a new 26 spline clutch disk and while i had it apart i also grabbed a new flywheel and stock OEM clutch cable...

Well after getting my engine completely overhauled and that brand new RMS started leaking, i changed it last winter and after driving it all summer now this one is leaking. WTH is going on here? Anyone else have this issue before? I have crankcase vents on both sides too. The seals i used were...

Hey gang, last night for the first time i noticed my battery light coming on when under a hard pull and close to top of RPM band. My alternator is a Mechman billet 240S with only about 1,500 miles on it. I refreshed my entire motor 1,500 miles ago and went fuel return also. I’ve never noticed...

Hey gang, this past winter in installed a Kenne Bell and a Lethal fuel return system. Everything turned out great and the car is a blast, however I’m getting a strong fuel smell now. Everything is tight and no leaks that i could see and no drips on the ground and filler neck gasket on tank is...

I’ve been doing research on how to set the spacing and from what i found you want the spacing between 1/4 to 3/8 from bottom of pick up tube to pan, but it’s never said if that measurement is from the edge of the pick up tube ( lip) or the screen itself . The screen sits a lot higher and i don’t...

I had my 03 Romeo engine completely overhauled a couple years back and i couldn’t be happier with it but i had him put an MMR oil pan on and it’s a great pan but i scrape everywhere with it, so while pulling the K member to do my Longtubes i decided to go back to stock oil pan . I found a brand...

So last year when i had my engine overhauled i had my builder put an MMR oil pan on it and i had just removed my K member to do my Longtubes and noticed just how much I’m scraping my oil pan . My car only sits 1.25” lower than stock being that I’m running the Eibach Pro Kit too. Another thing i...

I’m having zero luck trying to find a MAC H-pipe for my new MAC LT’s that i scored brand new off aBay . The only other option is a Lethal off road X pipe but all i can find on the site is catted, i don’t want catted nor does my state require them. Do you guys have any laying around? Sent...

Has anyone tried bolting a BBK off road H- pipe up to MAC LT’s and does it work? I’ve researched it to death and some say you can and some say you can’t . This winter i finally have gotten to getting my Kenne Bell on, my fuel system in, and my MAC Longtubes, however, i bought a used Pro Chamber...

Hey gang, by chance does anyone have MAC off road H pipe for MAC Longtubes for an 03 Cobra? I scored brand new MAC Longtubes last summer from a seller that decided not to use them , and he also sold me a shorty Pro Chamber that he had used that i also bought from him but it doesn’t match up to...

Would anybody happen to have a clear vacuum line diagram available for a KB 2.2 ? My car is also EGR deleted. I googled it but some of the diagrams look like my 3 year old son drew them with crayons and I’m not understanding them Sent from my iPhone using the svtperformance.com mobile app

Ok. I finally found some more time to get some work done on the Cobra with getting the new blower on, transmission/ clutch reinstalled, Longtubes and some cosmetic stuff. Since rebuilding my motor from pan up with all new everything, I’ve always had some slight blue smoke but only on startup...

I recently bought a KB 2.2 for my Cobra that i sent out to KB for a total overhaul front to back just for peace of mind . It got the works , new bearings, seals, gears, snout upgrade, hardware, polish , everything. While finding time to pull my ported Eaton off today which also just recently got...

I made a post before and I’m sorry if it is redundant, but i was very much hoping to get more info on your setups and opinions on my newly bought and refurbished Kenne Bell 2.2. I also then realized on past posts i and wasn’t very clear on my whole setup that i will have now after i install the...

Alright, my engine, trans, clutch, and IRS are all built with the best and by the best out there. Now for this winters final list for my 03 Cobra , it’s the fuel system, Longtubes, and the KB 2.2. I bought one used, sent it out to Carlos at KB and they did a complete overhaul front to back...

So, i just got my blower back from KB from a complete overhaul. I never ran this blower. I bought it lightly used and just wanted to send it in for piece of mind. My question is , the blower has a 3” pulley on it , how much boost will a 2.2 make with a 3” upper only? Sent from my iPhone using...
