svt versus standard zetec motor for turbo

i in the process of tracking down a long block to build for some heavy boost. i am curious if tracking down a svt block and head is really worth my time. i see svt has oil squirters in the block and the head is ported for performance and has vct. does any of this stuff help for a turbo motor that much or is it one of those things that you gain a couple hp out of the deal. i can have a stock head ported but i dont know about the rest as far as how much it helps. oil squirters will help keep the pistons cooler right?

This should probably be in the Forced Induction section, but if you're planning on installing forged rods and pistons, don't spend the extra money on an SVT setup. SVT motors are fairly expensive compared to Zetec. Now, if you are planning on using stock internals, then yes, SVT is far superior. The stock motors have handled over 300whp many times. 300whp on the Zetec is a lot riskier.

yeah i have found that the svt blocks are much harder to find and much more expensive and the only thing special is the oil sqirters and forged rods which i would be replacing anyways as far as rods go. i didnt know if the squirters were realy worth getting. how much will it actualy help with the longevity of my motor and the other thing is that i can find svt heads for realitively cheap. are they worth it. is the vct realy that helpfull in boost motors.

An SVT head will give you a lot of gains, but you would have to ditch VCT unless you wanted to run an SVT ECU and I *highly* recommend NOT using an SVT ECU. Run an SVT head with stock Zetec head gasket to get a little lower compression for safety. The oil squirters aren't really necessary from what I've seen. Multiple pushing over 400whp without them.

you know im curious. is there any benifit to using the svt rods opposed to say eagle forged rods. is the build any different on the svt say for longer life span. i want to build my motor not to just push power but to be able to drive without having to rebuild every 60k miles. i know things like the acl high performance main bearings can handle the heat and pressure of super high horse motors but they also wear out significantly faster than oe when dayly driving.

svt rods and std zetec rods are not the same length, or is it the wrist pin position between the 2 pistons is different?

No benefit between eagle, id go with eagle.

You can pick up the oil squirters from Ford for like $10 a piece and install them on the regular zetec block if you feel like it.

The only benefit to using an SVT head is the flow numbers. Using one without VCT will kill low end power. For what youd spend on an SVT head, talk to CFM, Massive, TS, or Focus Power, they all have ported heads.

Welllllp, just ask Pete, for one thing. He's tuned a couple of them. The inconvenience of taking 20 min to load a tune is almost enough not to use it. But then the other little idiosyncrasies that don't exist in the Zetec ECU are annoying.

There is nothing wrong with the SVT ECU , yes it takes longer to flash but other then that is as good as the ZX3

The SVT head will make no more power then the ZX3 Ford Racing head or a good ported head , My opinion is the SVT head makes very little more HP then the stock ZX3 head does
