Vq35hr Conversion

[T04GTR]

how do you change the title of a topic?

[Duncan]

Good to see this one moving along Dave.

Not sure if you can change the title, just let me know what you want it changed to...

[T04GTR]

VQ35HR conversion posibly.

[Duncan]

title updated, and moved to the builds section

[NXTIME]

LOL...Drunkan..I don't think he wasnted the title as exactly "VQ35HR conversion Posibly"

"VQ35HR into R32 GTR Conversion" would be more appropriate

[T04GTR]

lol. for exact title swap.

remade passenger header in a stinking hot garage this arvo.

obviously you're going all out (which is great) but considering all the modifications. is going VQXXHR really worth the extra cost over going just normal DE?

[T04GTR]

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.

[Duncan]

fine. so I am too literal.

[Leroy Peterson]

Interesting info.

I'd heard mixed things about the HR motors and the additional complexity when going standalone ecu. Wasn't sure if it was worth the extra cost of the motor itself.

[T04GTR]

passenger side header all welded up and stress relieved.

[zebra]

noice!

[Nismo34R]

Looking forward to seeing more! ?

[T04GTR]

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..

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

Nice work with the intake manifolds.

Are you planing to run water to air with that setup.

Regarding the exhaust manifolds; the merge collector spring retainer, will that not leak under boos boost pressure?

[T04GTR]

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?

[T04GTR]

no room, also shortest piping possible.

after some inter-netting, it seems to be the norm with inbuilt inter-coolers. if it is lazy, i can always re do it.

dump pipe finished minus sensor bungs

Epic fab work and workmanship. Keep the excellent work and updates coming.
