I have owned this car since I was 17 (22 now) and up until last fall it had the N/A 1.3l Rotary in it. At that time, I decided to swap it and put in an LS1 with a 236/236 Comp Cam, JTR long tubes, LS6 intake, etc. The setup made 402RWHP on 91 octane through a T56.

Well, I have always been into turbo cars and love the fun that they offer as a driver. Where I live, there aren't too many drag strips (Brainerd International Raceway is about 2 hours away) so most of my driving is done to and from work and to the grocery store. Of course, I still go out for some fun at night but the best times in my car are alone on the highway doing 30-100MPH pulls.

So, with that said, this is my quest to build a 700RWHP, 9 second daily driver that runs on gas that can be purchased anywhere (91 octane) and uses tires that can be used in the rain, if necessary (while it is a DD, it's a fair weather only car). I want to drive it to and from the track, up to my cabin, etc. So with that said, here's my build list. Please keep in mind that the motor has not been to the machine shop yet so the motor part of the list is subject to change. Otherwise, I have purchased pretty much everything else with the exception of the transmission and converter.

Here's the turbo kit:





Here's the rear end mount (it retains absolute stock mounting locations):



Here's a picture of some elses rear end in the mount (just so you guys know what it should look like):



Intake cleaned and painted:



Wideband/boost gauges:



FMIC mounted (I'll be taking it back off to repaint the front of the car):



Axles:



My DD is a Mopar by the way... an '05 SRT-4 that makes 340WHP:



Now that winter is setting in up here in the Northwoods, I'm going to start making some progress on the build.

Nice project man! Looking forward to the results. Did I read correctly that you want to run single digits on street tires?

Drag radials, yes.

Damnit man, thats a nice rx-7. I understand your quest for more power by way of forced induction. I will be watching this thread for progress.

damn, man... This car is SEXY.

Good luck with the build. It looks promising.

Awesome, what do you think the car is gonna weigh?

DavidPHumes

iTrader: (1)

Thanks man!

Thank you.

Should be right around 3,000lbs with me in it and a tank of fuel. Keep in mind it has full interior, stereo, power windows/mirrors, carpet, etc. It might end up being less, but not by much.

Nice!!!

Nice Rx7 is the the kit that was on FC with a red intake and valve covers?
where in MN are you?

gnx7

iTrader: (28)

great project. The FC generation ('86-91) RX-7's have quite a bit more room than the later FD's ('93-95).

This car will scoot for sure when done!

Thank you!

Thanks... it's been a long haul.

Haha, typing fail. If you have any questions let me know...

It's got a lot of clear coat on it

Nope, there's 2 other red LS FC's in MN, so probably one of those. I live up in Duluth.

Thanks! Everyone's so impressed by how much room is in the bay.

Alright, so I finally got the IC finished up (still need to do piping, but I have to get the motor in to do that and I still need to find an oil pan/windage tray/pickup tube):



The top is hard mounted:



I wanted some play in the IC, so I used these cut down rubber stops to help protect what little movement it may have (the IC pipes will hold it even more securely):



HID ballasts mounted way out of the way (don't mine the small amount of over spray ):



And a view from the back:

Some very small updates:

Got my roll bar today (AutoPower 4 point "race" roll bar). I'm having it powder coated black.

I know this thing probably doesn't meet NHRA rules for how fast I will be going, but as I said, this is 99% street car. If I can run a good solid pass and get kicked off, I'm fine with that. It will also be safe on the street as the top hoop is behind my head and behind the seat (the seat almost reaches the roof of the car).

I'm still going to take the girlfriend out to dinner in this thing (and drive it to work, and the grocery store, etc. etc.).



I also took the heads off of my 6.0 today. Found some major scoring in cylinder wall #3. This reaffirms my decision to put in a forged rotating assembly (I know I could get by with a hone and new rings, but what's the point of putting stock stuff back in if I'm going through all the work anyway?)

The motor looks like it was used pretty hard - lots of build up, etc. but other than the scoring looks to be intact (the scoring was really really obvious when running one's finger over it).

That's a clean *** car! I would love to do a LS3 swap in a RX7 or 240z one day... maybe when I'm done with the TA.
