VG30ET Swap
14 Attachment(s)
I realized I haven't posted this car up on here before, and I feel like this crowd would appreciate these shenanigans.
I'm President of Texas A&M's Society of Automotive Engineers, and one of our student projects (along with Formula Hybrid) is competing in the Grassroots Motorsports $20XX Challenge. So everything you see here is built by (largely unskilled) students for less than $2011. This car was originally intended for the 2010 Challenge, but some severe logistical issues (read: Not having a shop or tools) led to a delay 'til the '11 Challenge. The car itself was graciously donated by a member on here (I'm sure he'll stand up and identify himself). Here's a picture of the car when we picked it up, along with the car and our old Civic in shop #1. Attachment 189237 Attachment 189238 The car was cleaned up, and we dropped some components in to see if there was enough room. Probably not, but we decided to press forward anyways. Attachment 189239 The car then moved to shop (actually a giant lab not meant to be an automotive shop) #2. Attachment 189240 The first motor ended up being a bust, so we yanked another motor out of a (probably) healthier car in some guy's driveway. Attachment 189241 The engine itself fits rather comfortably in the engine bay, width-wise. It'll probably be poking up through the hood a tad, but that's not really a concern for us. Attachment 189242 We added some hardpoints in the transmission tunnel for a mount for the VG30DETT transmission. Attachment 189243 The mounts were extended down to the subframe, which was then reinforced. Attachment 189244 We picked up some used GC coilovers and possibly blown AGXs that we'll be running. If anyone has some stiffer spring rates that they want to trade, we're open to ideas. Attachment 189245 We got an old Cobra racing bucket off CL that didn't fit, but we widened up the tunnel about an inch and shortened the rails a bit. Attachment 189246 I cut away the front crash structure and welded in a length of pipe I found lying around, and we hung an eBay intercooler off it. Attachment 189247 Amazingly enough, it fit completely within the stock bumper. We'll probably be adding some speed holes in the top half of the bumper to increase airflow across the heat exchangers. As mandrel bends are simply too baller for this build, we've been experimenting with some unorthodox materials and procedures, and I think we've got a concept that'll work. We've used galvanized fence pipe cut into pie bends, and it matches up with the exhaust ports rather well. Don't worry, we're not going to actually weld the galvanized metal, we soak them in muriatic acid to remove the zinc before we weld them up. But yes, it actually works. We'll see if I can make an entire manifold out of it, but all signs point to "Probably." Attachment 189248 We're hollowing out the stock upper intake manifold and relocating the throttle body to the front of the plenum to make it more conducive to our packaging. Attachment 189249 We took apart out engine and threw some fresh paint on the block, then reassembled it with the old bearings and some fresh rings. Should be enough to last through the GRM Challenge. Attachment 189250 We painted the engine bay with appliance enamel from Walmart the other day, and should be dropping the motor in pretty soon. http://a8.sphotos.ak.fbcdn.net/hphot..._5094333_n.jpg That's about where we sit at this point. We've got a lot left to go, but it's nothing compared to how far we've come. You haven't lived until you've convinced a state organization to pay for something like this and give you somewhere to do it. Let me know if there are any questions about our antics. |

Awesome.

9 years until retirement... then some property big enough for a nice-sized shop and all my build-whatever-the-fuck-I-want dreams come true.
|
Much win. I need to find an excuse to go see the GRM challenge this year.

YUS! I always wondered if the 300zx tt engine would be a good candidate, I wish I had the money to try this on my own

VG30ET = 84-89 300ZX turbo. SOHC design, single turbo, not quite a cramped as the VG30DETT which was the DOHC and twin turbo from 90-97.
I'm surprised you guys didn't try to find a short block VG33E from a Fontier and have a 3.3L. http://www.xenonz31.com/vg33eswap.html |

Good to see another Nissan v6 swap going. As long as it doesn't taper off into a v6 coffee table build this'll be good. :giggle:
I'll get back to mine at some point.. if it wasn't for the cost of using my old miata... mine could have been a GRM build also :p AND I don't have a team! grumble grumble. |

I guess I didn't really clarify in the first post, we're not using a true VG30ET, we've got a VG30E block (with the higher compression) that we're turbocharging. We picked up an old Turbonetics T3/T04E off Craigslist that should work fine. |
Oh that looks like fun. Crank up the boost and forget about the extra cams... who needs em?
|
this would be something where a cowl hood is accepted.
|
WHOOP! Lookin' good Ags!
I don't have anything big to donate like Rob...but I have a few parts on the shelf. Also have a Momo wheel I'll donate. Let me know by Tuesday am as that's my last final day and I won't be back that way all summer. |

Looks good, but I didn't know that the et would take much boost. I guess it was the stock turbo that wouldn't take much boost.

When you guys picked you the car I know it didn't have any fenders on it, but I have some spares you are welcome to along with an old hood that is not presentable but good for mock up of cutting the hole and some FM sway bars for the 90-93 that I would let go for cheap.
I have a couple stock steering wheels around here that you can have for inspection purposes for your personal car. Let me know if there is anything else you guys need as I probably have it. |
I definitely will. What are the chances you've got a pair of headlight covers?
We've got a set of your daisies at the shop, still. |
