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?

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
