greddy twin build and beyond - 35vqde blog
4 Attachment(s)
I found a used greddy 18g twin turbo kit off the trusty internet a few months back and decided to pull the trigger…I think I got an amazing deal for the twins and the intercooler setup - everything but the emanage and the injectors…which I wouldnt use anyway bc I am running the haltech and deatschwerk 600s.
The catch to this purchase is that one turbo leaks and has very minor shaft play…so both turbos will need rebuilt…thinking of doing the 20g swap…additionally, I will replace all the hardware before the summer. taking this really slow (I'm still nuts deep in my weight reduction) - I don't have a ton of cash to throw at this and I need to upgrade a handful of items along the way. Which I will pickup and hopefully have everything I need by summer. I am going to modify the bumper and hood to allow maximum airflow - my main concern (after the turbos) is to dissipate heat. Large openings for the intercooler, radiator, oil cooler and side openings to move air up to the turbos and out of the hood. Here's where I'm at now: twin turbo kit C&R radiator - a used(although I dont think it saw track time) nascar stock (30"x18"x4") replica V2 front bumper heat wrap Attachment 451795 Attachment 451796 Attachment 451797 Attachment 451798 http://i1219.photobucket.com/albums/...f.jpg~original http://i1219.photobucket.com/albums/...8.jpg~original http://i1219.photobucket.com/albums/...1.jpg~original http://i1219.photobucket.com/albums/...3.jpg~original What I need: C&R radiator/oil cooler combo secondary oil cooler optional second hood hose line / fittings more heat wrap turbo sheilds 1 greddy BOV |
For the rebuild I recommend Blouch turbo. They did a very nice job on the turbo 996 billet wheel upgrade.

Thanks for the reference…they have a great website…
did a bit on the front bumper http://i1219.photobucket.com/albums/....jpeg~original wrapped the pipes and the x pipe Attachment 451799 |
Nice BUILD!!!! Keep us posted..:thumbup:

More cuts on the bumper…getting closer to final shape.

Nice work...just wondering about the structural integrity of that bumper...
|
The bumper fabrication is pretty kool idea in showing intercooler piping. It would be interesting to know the aerodynamic characteristic effects though.
|
Oo this is going to be fun!

spent my free time last few weeks getting my engine's front end off and getting the headers off…
The headers were easier to get off than I initially thought…the key was to remove the engine mounts and support the engine with the floor jack. Attachment 451801 Attachment 451802 I need a little lead time to have my turbos rebuilt so I am going to start fabbing up the radiator/oil cooler... |

had a little time to play around in the garage this afternoon…
the radiator propped up Attachment 451803 radiator & intercooler Attachment 451804 not sure how I feel about the bumper... |
Not the biggest fan of the bumper :/.

Are you planning on building air channeling ducts? Air will travel along the path of least resistance unless you force it in a direction. Having bigger holes in itself will increase air volume but will not necessarily provide better cooling.
I did that on my car which has intercooler, 2x oil coolers, condenser, and radiator stacked and noticed a huge improvement in water temps and oil temps. |
^+1. I think you've gotten a bit too concerned about overheating at the expense of aerodynamics and in the process you've lost cooling efficiency also. Air is just going to go around your IC.

Combined with the fact that it looks like ass.

thanks for the input…I have mixed feelings about the bumper aswell - I bought the bumper for $30, so if it shits the bed…not a huge loss. It's going to take a some money to get primed and painted as well.
@rcdash & suprasam - as far as air flow goes - I can see what youre saying some air will bypass the IC/radiator - which isnt the worst thing in the world(IMO) bc as it passes (on the sides & over top) it's flowing to the sides & top of the engine…I'm not sure if I posted this above but I intend to find a OEM replacement hood and add cut-outs to allow air to flow out of the engine-bay… I'm not against creating fiberglass ducts to direct air, I've thrown the idea around with a buddy who wants to create something similar on his car (volvo s60r)… |

With an aftermarket radiator, oil cooler, t-stat, etc, overheating isn't going to be a big issue. I'd invest in meth if you we're concerned, not to raise boost, but to lower intake temps. |

Word. Might also be worth looking into the pathfinder coolant mod and a shroud with high output fans.

James, you definitely don't need that large opening on the bumper. Think about the IC air flow capacity, it's approximately 50% of the IC area. Also, you must force air to go through IC core.
