Something a bit tasty

Quick question - what made you chose the DTM v2 over the oil cooler version?

mango-smoothie · Post by **mango-smoothie** » Sun Mar 14, 2010 7:41 pm

the regular DTM doesn't fit the 356 replica. the hinge squishes the oil cooler hose when you close the rear hood/trunk. it sort of works, but goes from a $800 part to looking like you shoe-horned a cheapo part in there. it also squishes the hose ~50% (can't be good for cooling).

that plus i run a massive oil cooler/fan w/thermostat outside of my engine bay (by the tranny) to keep things cold in there.

made some progress on my valve train setup

chromoly pushrods - uncut - weight 15% less

i still have to cut off probably 2-4 more grams worth of material on each.

also managed to get more lift on my cam (more than i expected and is advertised) when i was doing the adjustments. fiddle here, adjust there, move this, shim that.

using shims (0.050"), 911 adjusters, and had to modify the rocker arms 0.060" (and bevel them) to work with the adjusters.

hopefully everything works

added up all my weight savings in the engine / rotating assembly.

not including the flywheel i had lightened and balanced, i shaved over 1.7 pounds and balanced to 1g instead of factory 5g.

including flywheel - i shaved nearly 3.5 pounds!

i wonder what difference this will make... :twisted:

found an hour of garage time today and made an EDIS bracket and new all metal MAP sensor reservoir. my old one was PVC and worked, but was on it's last legs from the heat. this one's built for the long haul now...

bracket goes nicely behind the shroud (below the fan inlet and beside throttle cable). It's sooo easy with the engine out

also detailed my IDF filters / misc plates. wanted gloss black instead of semi polished aluminum

built up oil pressure without plugs (~1 min), ran it @3K for 20 minutes

Very impressive. I have just built this 2056cc for my coupe. Quick question - have you used any of the original cooling tinwear underneath the cylinders or is it just the dtm and the aluminium pieces that surround the engine?

mango-smoothie · Post by **mango-smoothie** » Sun May 09, 2010 10:39 pm

yes - all the OEM cooling tin is there. actually there are only two pieces (one on each side) - but there are both there.

Who is the exhaust header made by ?

mango-smoothie · Post by **mango-smoothie** » Thu May 13, 2010 6:15 am

a company in california called A-1. There is a dude who works there named Tiger. no i am not yankin your chain.

it's a very expensive unit, but top quality. i think i paid $700 for just the header and stub pipes. i then bought a magna flow muffler 2.25" inlet/outlet on same side and fabbed up my own dual center exit (bought a few extra flanges from tiger with mandrel pipes came to ~$80. muffler sourced locally for ~$200

all and all an expensive exhaust, but sounds nice and has crazy clearance

Are you running breathers in your rocker covers?
I have been advised to drill the rocker covers and fit breather pipes up to an oil breather tank? If so any advice on where to drill the holes? Seems a bit odd to me as i thought it might affect oil pressure?

i did have the valva /rocker covers drilled and vented, but on this build, i decided to vent the head itself.

here is a shot of the placement:

i decided to do the heads and not the covers because of the angle of the vent hose, with the current placement, it's a much better fit to the breather box.
