LS1 RX-7 rebuild/build 4l80e, Ronin 8.8 and turbo
« on: July 19, 2012, 02:39:12 AM »
So a lot has changed in the past year.  I have two turbo ls based rx7 builds.  The newest edition despite my best efforts still needs some love.  I decided I was not going to be happy with it unless I tore it all down and started over improving upon it (there were tons of things that drove me crazy or just didn't work).  Also the New (light blue car) is just rough inside;  Needs new interior trim, has a shitty roll cage needs all new chassis wiring, the turbo kit is a pile of shit, the motor is on its way out the door, etc. 

Long story short I decided to swap over the usable parts of the build into my other chassis and give the rough car the "racecar" treatment.  So here we are

Plans in the immediate future are;

Engine:
forged LQ4, JE pistons, k1 rods, stock crank
Modified hinson single turbo kit
243's with ARP studs
LS6 Intake w/ ported throttle body
Cam motion custom (baby cam) for turbo

Drivetrain:
Beefed up 4l80e
Billet converter with a ~3000-3200 stall
Solid 8.8 axle conversion

Redo the turbo kit using a Hinson hotiside kit and just go from there
I'm leaving the other build information for reference to anyone it may benefit and moving in this new direction.

Here are a few old pics of how the car once was:




Havent decided how crazy I want to go with weight reduction.  Leaning towards keeping the interior and at least a basic stereo..

In preperation for the lizard skin that ill be applying I started working on removing some factory stuff.
Made some more progress,  working on removing the factory sound deadening...






Still have a bit more around the transmission tunnel but I was out of dry ice and over working on it in the 105 degree heat

More to come

So started on the interior with alot of help from ray.. thanks bud :thank_you2:
Having an extra set of hands to mask everything off was priceless
Started by striping everything remaining out of the interior except for part of the harness which I wrapped up to protect it.





Then realized I only bought the heat insulation from lizard skin :suicide:
So ended up doing a mass loading rubberized coating as a base which the heat product will go on top of.
Went to work






Sprayed pretty much everything, floor pan, doors, roof, hatch, everything I could get to





Now need to wait for this stuff to dry then start spraying the heat insulator :laugh:
Then I have some more sound deadening crap to go on top that is very light weight and orders some new black carpet since mine is done.


More to come...

So kept working and applied the first coat of Lizard Skin CI





Some close ups.  It looked like a very fine spray on bed liner when I was cleaning up but felt pretty soft may change as it finishs drying






Going to take a look at it tomorrow and decide if I feel like doing another coat.  It shouldn't need it since I already made two passes and laid it on pretty thick.

Worked on the car for a while today, didn't feel like doing anymore prep and masking...
Was thinking about skipping doing the engine bay but ultimately it made sense to do it all now.  The bay is beat up and paint was flaking off in a few places pretty beat and weathered.
So started prepping the bay and masking.. blah


Sprayed the bay with some high temp flat black paint.  Did two coats.




Very happy with how it turned glad I didn't get lazy
The rest of the time I spent dicking around with the interior and putting a few pieces back in.  Got the headliner and sunroof stuff in, sun visors, and put most of the back plastics back in.
Laid out some crap

More progress, waiting on my new carpet to arrive. Needed to finish up all the sound deadening in order to be all ready to start on the carpet when it shows up (hopefully tomorrow)
So far I did a mass loading rubberized coating, then Lizard Skin the last step before the carpet (which also has a backing product on it) was another product by Raamaudio called Ensolite which is a sound deadening and heat isolator which is also fire retardant.
Big thing is Its very light so you can go crazy with it without it weighing down too much.


So began the slow and painstaking process of trying to get 100% coverage on all the interior where the carpet and dash / pain to remove stuff will be.


Start
first door was a little shaky never used this product before...


Second door

Starting the dash


Making progress



All of the car forward of the rear bins done



Ran out of stuff even though I bought more than the "recommended" amount for a small car, need a bunch more to finish but at least I did all the stuff that the carpet will cover.


Started making/modifying my brake lines for an ABS delete, going to see how it turns out before I deiced 100 percent if I want to eliminate it.




Alos started finishing up extending the Harness to relocate the pcm from the passenger kick pannel area.  Need to extend about 10 more hours and pretty it up.

So today got some speakers in the mail, along with my new motha fuckin carpet.  Couldn't have been happier about it either.  Went out and started tinkering with the speakers and fumbling with their mounting (for way too long) then did this.  The speakers are some fairly nice infinity's that should run well of an aftermarket deck.

Put in the factory firewall sound deadening blanket, then moved on the the carpet, its a cheap carpet that IS molded but you have to cut all the mounting holds and accesses.  Did not think it would have been such a pain but it was... Now its done.


Started doing this, cutting some backing to level out the mountainous floor pan design.

Kept doing that and triming until the carpet laid nice on it and then began the process of trying to cut holes for everything, seat mounting, restraints, etc there was a bunch of crap to do.  Took my time and kept chugging along.


Then fought with the dash for a while

Started trimming the overage of the carpet around the edges and finally called it a night, hands are raw and my back was pissed from hunching and contorting in the car a bunch again


more soon.
