Mid Engine Cobalt

I didn't want to hijack this thread but here we are:

Our company's roots go back to when we posted our first Goblin prototype build log on a very receptive forum. Before that, it was just an idea between a father and son to Frankenstein a car together by using the leftovers from a Cobalt. If that forum would have been hostile to us, there is a good chance we would have stopped sharing anything on that forum and never would have seen interest in our car as a product instead of just a project. Who knows if any of you would have a Goblin if it had played out any other way.

That forum helped us out so we always knew we would benefit from having our own forum for people to share their progress, get help with questions and possibly throw out ideas they are working on. That is why we launched our first forum before we even had our first orders. And we are so glad that we did.

Many of you guys might not realize how big of an impact you have on the Goblin community and our business. Almost every single first time visitor to the shop and most guys calling/emailing us end up talking about a forum member or two by their screen names and telling us about how helpful they are or how awesome their builds are.

Over the years the forum has been sustaining itself as a positive environment without any input from us. However, we've been pushed over the edge by Mayor West and the many reports we've received from other users about his posts.

Mayor West's recent posts in this thread and many others have been needlessly inflammatory and are not acceptable if this forum is to continue to be a decent community. For that, he is temporarily going to be marked as a "Limited User." He will be able to view threads and add to his own build thread but he won't be able to post or direct message anyone through the forum for the next month.

We are not afraid to take more drastic action in the future to protect the forum.

Thanks. That was wholly the reason I suggest people go back and read through the time you guys spent on Grassroots. Its a great example of; in many ways what this forum has become as well and should continue to be.

I actually have read through it, I like seeing the changes y’all went through to get where you did. I will likely start a new build thread to clean the slate once I start. I am very happy to know that I can post here and get support. The negativity was luring me else where... I really want to work with y’all and hopefully begin making a goblin in the new year. I think I need to visit JBINTX again to make sure my head is straight.
If what I do can lead to progress for DF as a whole, I don’t care if they profit from it. I am in no position to try and produce a product like theirs. Hell, once I am done, I wouldn’t mind leaving it at their shop for a bit for them to comb over and use what I did to benefit others.
thank you and I really look forward to hashing over the parts list and a quote in the very near future

Okay guys!!!! You just lost my participation in Goblin building. Enjoy your journeys!
Good morning Dale, I really hope that you don't leave our forum.. I really enjoy seeing you on here and talking to you at the meet ups.. I am hoping that the problem has been fixed and that EVERYONE can post and feel comfortable doing it... Lets be kind and respectful to each other on here.. Thanks,

I hope I do this posting thing right

Just some things to share along this line of thinking and for others consideration. Call it a study in design, a proof of concept model. This will not be going into a Goblin, since I am too old for more cars and already have too many toys. This is a hobby and fun to tinker and waste time. Hope someone gets some benefit from this.

Yesterday, October 1st, was a very busy day. I went to the pick and pull and pulled this HHR (Cobalt similar) engine cradle, one control arm and a hub. Then I went to my shed and rearranged stuff and loaded up my 3800 SC V6 onto the transmission (these are from a Pontiac GP/Buick Regal GS). Situated the HHR engine cradle underneath and laid her together - with various wooden aides - to approximate location. Would / will not be hard to make up some mounting brackets to make it all hooked up. The pictures show it not quite level, since my wooden aides were just scraps I had handy. I have a computer to make the engine start and run, but need to make up a wiring harness and mounts. Then it all goes away -- experiment over / done!!

COBALT track width: Front 58.7 --- Rear 58.1
HHR Front 58.7 --- Rear 58.7
MALIBU Front 59.6 --- Rear 60.0
IMPALA Front 62.4 --- Rear 61.5


Everyone has talked about different engines being used, and since I already had one with automatic transaxle, I just did a mock up! Engine cradle with the one control arm and hub cost me 175.00$ at pick and pull.

Thoughts?

NAKED HHR ENGINE CRADLE WITH ALUMINIUM CONTROL ARM

NAKED HHR WITH VW TRANSAXLE CASE. THE 3800 V6 NA/SC IS 18 INCHES FROM BELL HOUSING FACE TO BACK OF HARMONIC BALANCER PULLEY. THE ENGINE CRADLE WOULD NEED SLIGHT MODIFICATION TO ALLOW OIL PAN OVER IT, BUT IT WOULD STILL FIT BEHIND THE GAS TANK. THE TAIL SECTION OF THE VW TRANSAXLE IS ABOUT 8 INCHES.

NOTICE THE TRANS MOUNT IS ON THE CRADLE SIDE (DOWN) THE MALIBU CRADLE IS THIS WAY ALSO AND HAS A MOUNTING BUILT ONTO THE CRADLE ALREADY, THE BACK OF TRANSMISSION IS EVEN WITH THE OUTSIDE OF THE ENGINE CRADLE TUBE..

ENGINE FRONT. THE BACK OF HARMONIC BALANCER PULLEY IS ABOUT EVEN WITH THE ENGINE CRADLE TUBE.

REAR VIEW. WOULD MOST LIKELY HAVE TO SHORTEN THE DRIVE SHAFTS TO FIT THE COBALT / HHR WHEELBASE. OR MAKE NEW LCA TO FIT FACTORY LENGTH DRIVE SHAFTS.

FRONT VIEW. PLENTY OF CLEARANCE FOR EXHAUST HEADER, SINCE THE FRONT EXHAUST LOOPS OVER THE TRANSMISSION AND JOINS THE BACK ONE (NORMALLY). EASY TO TURN INTO DUAL EXHAUST.

SIMULATED GAS TANK PLACEMENT SHOWING CLEARANCE. AND THIS VIEW SHOWS MORE WEIGHT DISTRIBUTION TOWARD FRONT / MIDDLE. AN LS4 V8 WOULD HAVE A LOWER GROUND CLEARANCE AND WEIGHT DISTRIBUTION WITHOUT THAT HEAVY SUPERCHARGER ON TOP, PLUS THE V6 IS AN IRON BLOCK. THE LS4 IS ALUMINIUM.

IMPALA ENGINE CRADLE IS ALUMINIUM WITH AUTOMATIC TRANSAXLE. IT IS BIGGER-- YES-- BUT ALSO NOTICE THE LARGE FLAIR-UP FOR CHASSIS MOUNTING POINT.

Haha, I am not ruling out a super or turbo charger in the future, I want to get it all together with about 400 hp and go from there.
Side note, there is a video of a twin turbo draken spyder making about 1100 hp and weighs about 2000 pounds. It runs a corvette transaxle and Erod ls3 from the factory. It looks very streetable somehow.
