when you have seen both motors apart, yes.

forced induction is not really that much differance in cost once you include a new intake manifold for the de,but having said that, there is a crapload more bits "off the shelf" for the de.

bearing diameters are all alot bigger.

heads flow just as well as ported de heads out of the box. and the crank is much better,less harmonics and the block is alot stronger. with the nismo oil pump im using they are reliable to 8500. so nismo says.

one thing that needs to made avialable is 3d printed rocker covers with a re-located oil filler cap, and replaceable spark plug tube seals. same for the de really.

im also suprised that the full on drag guys still use the de as a base. (billet engine block) when the design of the hr block is way better for main bearing support. and if made billet they would be nothing stronger.

making some headway with the intake manifolds.

not much room to work with, between being to tall and wide and keeping the overall volume as tight as posible has been a challenge.

this version was way to big in volume. not planning on making 3000hp..post-19586-0-73439500-1451449157_thumb.jpg

this version was all i could come up with with the available space.

finished the intake manifolds apart from the balance pipe. and supports also the water to air pipes (i haven't worked out where to put it yet.)

each maniflod with the intercooler is about 4L. about 1 liter larger than i hoped but what can you do...

the charge pipe from the turbos will be a short 2" 90 and a 2" to 3" 90 degree reducer.

the water pump for the heat exchanger is a jabsco cyclone 32gal/min.with 3/4" hose. il be using 1" hose. i chose that over a Johnson cm90 because it flows more at the same head and is more compact and cheaper :)

How come you chose to run them straight off of your plenum instead of run the plenum size you wanted and have the heat exchanger seperate?

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
