Hello all



I have a 01 Cobra and I want to get some HP's out of it. When I bought the car, I actually never wanted a supercharger but now.... I only wanted to install some cams Stage 1 or 2, because I like this oldschool muscle car sound


I read good things about KB and I also like the look of the rootsblower. I thought I buy first the non-intercooler version with the maf & cai kit so that I get 6.5PSI of boost. But maybe I want more boost and buy a intercooler upgrade kit. On the KB page, they write 9PSI is the max boost with stock rods & pistons. So I thought I install forged pistons and rods, I think that would anyway better for the engine. But for the installation of the pistons & rods, I have to put out the engine?? If yes, that would be the best time to change the cams too.

Can some one recommend some cams which I can use with a supercharger? Stage 1 or 2 are enough.

And now the last question. Here in Switzerland, we have some strict regulations about car tuning, specially engine tuning. When I "tune" and want to get a street permission, I have to do some test at a test center. One of it, is a Emission test cycle. If I comply the emission standards of 2001, I get a permission paper. I know very difficult, but you can get very high penalties if you tune your car without a street permission for that. That's a bit OT, sry.

My question is now, I what way change a supercharger the permission of a car?


Thanks, for any help

a competent tuner will be able to get your car legal. changing cams to something fairly aggressive can make it hard and you have to be wise with your selection. if you have a local performance shop there and familiar with the modulars and tuning, then i personally recommend taking their advise.

I know a car tuner in germany (3hours from here) and he knows his business. In the mustang forums here I always hear his name. I also talked with him some months ago, because the cam install. He told then, that they will remove the heads anyway, so I think in that case it wouldn't be a big deal to change the rods & pistons. He also change the head gasket, bolts and they would also grind the valves or something like that.

I have to ask this guy, how much more it would cost to install the new pistons & rods. Last time he told around 2100euro for all incl. dyno tuning.

The heads don't have to be removed to do a cam swap.

I like the MPH Blower cams, when I was building the Mach I got my cams from them. Also, while the KB is nice and fun on the street you are somewhat limited. Have you thought of going with a centri blower or turbo? What are your power goals? What is your budget if you don't mind me asking?

[agent-orange]

@NA SVT
He told me, that it is easier when the cylinder heads are removed, donno?!

But if he would do it anyway, he can change also the rods & pistons.

@futureMACH1racer

Turbo is nothing for me, that's more for a rice burner :-) I don't want tune the car to much, max. 450-500HP. The problem is, when I tune it to much, I may have to upgrade the brake system. But so far I know the 01 Cobra has the same brake system like the 03/04 Cobra's?? My budget, about 8-9grand. But sell the car is not an option for me, because I live in Switzerland and here aren't many cobra's to buy.

The heads do not have to be removed to change the cams and it surely doesn't make a cam swap easier, but does add a significant amount of labor. In fact a cam swap can be done in a few hours without removing the engine. Also, changing the rods and pistons requires machine work and a lot of other parts. If you don't plan to go with forced induction you won't need forged internals.

Go with cams that use the stock valvesprings, it'll save you a lot of money without hurting power.

Ok, I have to talk to this guy, why he wants to put out the cylinder heads. What is the max. power for my cobra when I use the stock rods & pistons?

[futureMACH1racer]

To be honest if you want to go with a forged lower end, then I would just buy a shortblock from a reputable shop. Install a blower of your choice and be done with it. Stock cams, leave the heads alone, and enjoy the power level of your goals with stock drivability.

450, but even then the engine won't last forever.

[agent-orange]

when I want more?? Do I have to change the pistons & rods or something else too??

[futureMACH1racer]

The stock powered rods can't hold up much farther than that. I mean you could push that kind of power on the stock lower end but I wouldn't expect it to last forever. Ask me how I know?

something tells me that something terrible happened to your lower end... lol

@futureMACH1racer

Where can I get a forged lower end, do you know a good shop?? The problem what I will get here, is the transportation. I think that would cost about 1000$ or more.


Edit: Anyway, I will do this next year after the winter brake, but then the car gets repainted for of all.

Another question, what is max tolerance (HP, speed??) of the brake system? Minimun 390hp?

A fully forged shortblock is going to run you about $4000.oo Depending where you go. MMR has really good prices, as does DSS, Livernois Motorsports, CHP, to name a few...

[na svt]

this is the best deal around, and it comes with an aluminum block unlike those from DSS and MMR: JDM 302EF Stroker shortblock special!!!

[futureMACH1racer]

WAP Blocks have been known to split around 600-700.. No wonder it's cheap...

Arghhh...WAPs won't split at 600hp and for the intended power level that block will hold up well. I know people running them at 700rwhp and have been for a long time and they've expereinced no problems. This is one of those internet rumors that has been going around for years.

@NASVT

thats really a good offer. How heavy is this short block ~? 302ci that would be a 4.9l engine. What's the min. power I get because of that? So far I know, bigger engine size means more torque and more torque means more HP's, or is that wrong?

It's no heavier than a stock, aluminum block, cobra engine. What do you mean by minimum power? The power level is going to be determined by the heads/cams/intake combination andif this was to be used as a stock replacement it would make about 20rwhp/2-rwtq more than the engine it's replacing.
