New 5.4L DOHC Intake for Navi heads - Pics Inside!

DOHC330Mustang said:

The 5.4L DOHC Intakes have shipped to Modular Performance. I expect a week to get to MP, then a week to arrive at my (customers) doorstep. If you haven't ordered, I'd do so this week while the first batch supply lasts!

Regards,
John

Great to hear man. I tried to message you on aim this morning but you didn't respond...

I was wondering when you plan to start putting your engine together and drop it in?

It's ok about the aim thing. I was sure you were probably afk or something.

I thought you were talking to that guy on corral or modularfords about gettin those other spring setup with titanium locks/retainers? What is special about the ones coming out vs whats already available? I know your probably getting impatient with all these parts laying around and not able to get that baby in and running.

man this is sweet. so the engine itself is 2500$ (used),3700$(new). found navi heads for 850$/each. from there what else is needed? efi, either tec 3, FAST, or from a cobra correct? exhaust manifolds/headers will need some massaging. anything else? if thats all then doesnt seem to bad, or too expensive. as far as supercharging who cares, i can run nitrous until cobra killer makes one or go with a turbo. what components did I miss? sounds almsot too good to be true.

Yes the swap doesn't appear to be too bad...i can't wait till a couple of these guys get dynos. Basically you have to bend an a/c cable which is obviously no biggie, the intake problem is now addressed (atleast for n/a applications), Its close but a direct fit, Youll still need ATLEAST a cobra R hood and possibly a tubular k-member to drop the engine another 1-2 inches in the engine bay. Like you said you'll need to get a cobra exhaust manifold and shafe the flange a little (not to big of a deal)...did i miss anything? Wiring harness should be a direct fit from GT or cobra setup and computer will also work interchangeably.

dohc330, did you order the fuel rales they have now for the spider intake or you waiting? Is there anything else you need to get the intake part working properly?

Some things i've been wondering is how does the 5.4L australian and cobra R setup have 390hp. That would equate to 330-340 rwhp. Is it all in the intake or also with the cam profile or what? The navigator 5.4L supposedly basically the same heads but just breath better put out out pretty miserable power. I just want to make sure that its worth the swap n/a before i go supercharger on top.

turbo + 5.4L would be wicked power...and so will a twin screw + 5.4L. Thats the idea.

If you have navigator heads you probably can go to a junk yard and buy a crapped out motor and rip everything off to use the block. I plan to look for a good condition junk yard navigator motor. If you think about it you really dont need to buy the almost new engines. Your going to end up building the internals of the engine anyway in most cases...so whats the point? If the rods are damaged etc. it wont matter they are being replaced.

I would like to see someone writeup a comprehensive list with price ranges for all internals for this swap. That will help people see the total cost for gettin this setup running with this intake.
