Calm down.

Measurements over attitude would be more useful.

good to see someone putting some love on a DE... especially because the tq curve doesn't compare to most of the stock VE's out there when it comes to whp-tq comparo.

keep it up bro... it would be sweet to see a 250whp DE rappin VE's really hard and then driving it home

With the Tri-Y, when modified and routed this way, Primary 1 and 4 end up being slightly shorter by around 2-3" i believe.

The big tube Tri-y header has stepped primaries that are 1.75",1.875", 2.0" O.D.

The secondaries are 2.1".

Thanks for the sizes. Also, did you merge 1&2 and 3&4 or did u do the regular 1&4 and 2&3 pairing?

Sure I'll drop you a pm with my email if you want to discuss the DE itb setup.

Do you think it will affect it much if 1&2 are longer than 3&4 and they are paired that way?


Lets assume 1&2 are similar length and 3&4 are similar length, would you pair them that way or rather pair say 1&3 and then 2&4 to get one long and one short primary together?

Yeah as said, its paired 1&2, 3&4.

I dont imagine 2" is going to make too much difference. Its not perfect, but as close as i could get.

So i finally got around to modifying my Mazworx header, so it now has 10" shorter primaries and a smaller choke diameter.

Here is what i ended up with:

*I have also recently changed over to a VE head on this car. I'll start a new thread in the VVL section soon once the car is running.

what cams in the vvl head?
2012-06-16 18:22:23
Blood, i got hold of a 16VE motor, so i'll be using the stock 16VE cams and also 16VE pistons.
