1994 Rx7 LS7 Build. And The Journey Begins
« on: July 31, 2015, 10:50:06 PM »
 
LS7 will be the main motor not the LS3....Change of plans


Well everyone here we go......I am jumping in this and never looking back. I got my automatic FD a couple years ago but now I am finally pulling the trigger. I decided immediately to do this when I bought my wife a new 2015 Mustang GT Premium for her birthday. 430 ponies in that thing felt real good and made me so jealous...... But nothing like my buddies LS2 procharged GTO.....That thing rocks....

So my end goal is an 416 LS3 forged and magnum 6 six speed. 8.8 Explorer rear end with 3.73 gears. Long tube headers and 3" exhaust. Ported intake and heads and I think I can get to 500 RWHP. I will need everyone's help on this as I am not the professional wrencher but good with tools and following directions. I have read a bunch so far so I am following a couple people already to get some ideas. First off is selling all the 13B crap and rear end. so here is a couple pics just to get the ball rolling.

I already pulled the front radiator, inter cooler, bumper and all the other crap up front. So no turning back now.

I know you haven't gotten that far yet, but maybe someone else can chime in, but how hard is it to swap an auto car vs a manual car?
Is it worth it?

It's not hard at all, you swap the brake and clutch pedals and can either plumb the clutch into the brake reservoir or use a separate one.  The wiring doesn't change much either.  I bought an auto for my swap because it was a lot cheaper back on '05 when these cars were really popular.

I agree. Some people make it sound too hard bit if you really want to go all out. Here is a link on a step by step procedure. I think it is overboard but it gets the job done. I am doing a LS swap so don't need to modify engine harness just use an F-Body harness and I should be good.

Update. Well I got the 13B sold and will be ordering the complete Ronin Speedworks LSX Mount Kit Supreme with the 8.8 Kit. Getting the 13B out was a PITA........

Question: Will this kit be good for hood clearance on an LS3 with a Fast 102 Intake? Or will I have to settle for the 90?

Have you tried heating the bolt and letting it fully cool?  PB Blaster maybe...

Is the bolt seized in the bushing? Did you try heat?

Never tried heat yet. I pb blasted the hell out of it. What it looks like the bushing is coming out with the bolt. That is not good.

It is a good time to replace bushings anyways. I would try some heat on it. Pb blaster prob won't to shit. You are bending the crap out of the upper mount.

Try to get a breaker bar with a impact socket. Try to break that loose.

This may sound ODD but try using clean brake fluid on the area. My mechanic buddies swear by it when PB blaster does nothing. Be careful with brake fluid, it will eat paint if left on too long,
