More!!!









Mounted my FPR and started Running some little -8 lines

How many moneyz was that intake? Looks killer!

[stbrn19]

The intake is a precision metal craft intake, i think they go for just under 3k new. I wasn't baller enough for that so I got mine used

Fast 90 is 6 and 5/8" from valley cover to high point up front.  Just measured one

[stbrn19]

Got my cam, put that in and buttoned up the front timing area, need to leave the front cover loose as im going to most likely put the returns to the turbo in it. 
Put some DEI sleeves on my fuel lines and played around with my fuel line routing under the intake manifold









Made a stronger mount for the FPR

awesome build!

So took my car over to brooks racing (a few suites down from my work) to have some subframe connectors and a trans mount fabbed up.  I'm extremely pleased with the results.  Subframe connectors tie into the rear subframe mounting location and terminate just behind the front subframe (but does not tie to the front subframe).  The trans brace acts as an h-brace for the subframe connectors.  An additional h-brace will be added later that has a drive shaft loop.






When I got the car back I did a few things I had been putting off;
-Massaged the firewall so the rear fuel line fittings will fit
-Finished the rear fuel line Y and put heat sleeves on it
-Installed a throttle body
-Mounted the coil relocation brackets
-Stared at the car for long periods of time

Back from the dead...
Played around with a few things, Been going back and forth on how I want the cluster/gauges to be.  I ended up modifying the stock cluster to remove the factory water temp and oil pressure gauges (which blow, and my oil pressure sending unit is broken).  Put some cheapy gauges in but I have used this brand previously with good results.
Dissassembled the cluster and started to dremel the cluster to make room for the new gauges:


Test fitting the gauges after removing the gauge faces:



Cut up the back of the cluster to make room and ran the new wiring through:




Random shot of fitting the lens over the oil pressure gauge:



All fitting and lenses drilled for the button:



Shazam:



Pretty happy with it so far, i'll have to see how it is some day when i'm driving the car again...

when do you plan to have it ready to drive?

[stbrn19]

I'm undergoing some rather large changes in build plans yet again.  When I have something significant to update powertrain wise i'll spill the beans.  Hopefully it will be moving under its own power within a month... It may take longer (and most likely will).

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


Here is the car as it sits, I have spent a ton of time on it the last few weeks and its getting close to being ready to fire up and break in.
The progress highlights:
The hotside




All wrapped in DEI titanium wrap





New wastegate sitting in its new home



Radiator position



New intercooler Treadstone was nice enough to send it to me custom dented...




IC mock up

[stbrn19]

I got a tig welder like 7 months ago and was busy with work and a little unsure of how to use it, I got it out and watched some youtube and read some basic theory and started playing.  Heres day two trying to weld up some IC piping.  It could be better but i think it will work.
First weld on aluminum tube






Need to bead roll the piping, wanted to keep the couplers to a minimum.

Have tons of crap left to do but wanted to share some progress.

[N2v8fcs]

I like it!

[stbrn19]

Thanks man, I'm hoping to make some more progress this weekend

So i'm not happy with the radiator fitment.  I modified a hinson to fit as good as it could given all the crap in the engine bay but that left less than enough room for proper fans and hung down very low to the ground.  Being in Phoenix, AZ where its hot most of the year I needed all the help I could get.  I have had my eye on a few peoples builds in particular mefarri and 1point3liter and decieded to just order the Howe's radiator with the 24x15 core and move everything as far forward as possible.  Having the pictures and wealth of measurements helped to save me a ton of time, thanks guys.  I had previously cut out my front crash support ?(whatever it is that ties the two frame rails together). Once I decided screw it and ordered a radiator, I cut the additional front cross beam that the hood latch mounted two.

Before:

After some cutting:



Made the first part of the new structure to tie the frame rails together here are some pictures thus far.


The bar where i left it tonight:





Need to weld some tabs on it to keep the hood latch and wait for my radiator to see how it will all come together.


Also worked on my downpipe and got it pretty much wrapped up  have it terminated near the starter and need to figure out wth i'm going to make for my exhaust.  Don't have any pictures of that.  I'm trying to get a feel for the using my TIG.  The aluminum and stainless that i have done so far went fairly well.  The mild steel cross bar welds were less awesome and it was harder for me to do with the little radius narrow bar.  O well still need more seat time.

Also the hardware is just to test fit it i ordered some oddball flush head bolts to deal with the whole clearance issue.
