Installed PAC1218 valve springs + Trickflow Cam ground for boost.
Should be ready to fire up pretty soon. Can't wait to see what this cam sounds like. I'm contemplating to get the thing fired up in the car naturally aspirated first just to check the health of the motor.

I'm envious of you. I can't wait to drink the Sloppy Turbo-LS Kool-Aid on my own fox platform sh**box project.

What did you end up doing for engine mounts?
Did you go AJE for the cross member?
Are you going with a KB Racing Log manifold (or equivalent) for the turbo hot-side or building your own?
Stock ECU or Megasquirt?

Keep going! Can't wait to see the finished product.

I am going to go with the AJE k member. It's only 280 bucks and seems like it is a bolt on piece.i can even use the stock struts which is nice. I'm not exactly going for a corner carver! I will use the AJE mounts made for their k member (68 bucks).

i will be using stock ecu with hptuners. Yesterday I picked up a stock ecu from a 2000 gmc 4.8 sierra. From the research I've done this should be the easiest pcm to tune and get up and going. One of my buddies bought the HP software so this should be a great platform to experience and learn with.



For the turbo kit I am still researching what the best way to go is. I'm in between ON3 kit and vs racing universal setup with a premade log manifold. I've still got a long way to go before I need to buy turbo parts.

Picked up 2 fox body rear ends 8.8's, one has 3.15 gears and one has 3.73 with a spool. I'm thinking of using the 3.15's what do you guys think ?

Pulled the stock gas tank out. This is a southern car and it still has a few rust holes in the trunk floor. Perfect for weight savings
Got the stock tank out , I'm still contemplating getting this thing sumped or maybe going with a fuel cell off craigslist. If I ever decide to do hot rod drag week or hot rod power tour it would be nice to have a full trunk!

Today I pulled apart both of the 100 dollar rear ends to see what I'm working with. The first rear looks like it has an upgraded Richmond 3.73 gear set
Second rear has 3.08 gear set , they should both do the trick for this project. If one blows up I have a backup !

Got the AJE k member all bolted up. I'm going with stock springs ( any input on how the stock springs will work with the iron 4.8? I'm also going to throw some new ball joints on the stock lower control arms , as well as some new struts from rockauto (40 bucks ea)

I'd say go with the 3.73s mate. Front springs should be fine with an iron block after all the old 3.3 lump is no lightweight

This weekend I ripped into my 4l80e with a buddy of mine. We installed the transgo HD2 shift kit and it was not too bad at all! I've never rebuilt a tranny or ever installed a shift kit so this was definetly a learning experience. The instructions were pretty straight forward and watching denmah's YouTube video on the install a few times really gave us confidence!
Of course we used all the firm shift springs! No slushy shifts here !

The harbor freight engine stand really came in handy
I'm not going to lie once you crack into this thing it's pretty daunting.

circle d spec'd me this 3400 stall triple bullet converter, damn this thing is a piece of art! It's quite funny when your torque converter costs more than the car !

I have a 5.3 in my Zephyr with 3.73's and I run out of gear really quick on 5lbs of boost. I'm going to be going to a 3.27 or 3.08.

Have 3.55 in mine. Going through the traps at 6000 at 130ish mph. Going to leave them in for now and maybe try some 3.27 next year

I spent an hour yesterday pulling out the stock 7.5 rear end, the fox body 8.8 with 3.08 will be going in next.


Here is after we dropped the stock rear out of the car



I'm waiting on stock lower control arm bushings to reassemble the front end.



Here's the old stock 7.5
