Very nice! The car is definitely coming along nicely! I really liked what you did w/ the ducting. Maybe I missed it, but how exactly did you secure the the ducting itself? For both the intercooler and oil coolers?

Ryan

The radiator / intercooler ducting is two pieces. The bottom piece bolts up to the frame rails from underneath. The upper piece just rests on the top of the intercooler but is pressed down and secured in place by a bracket that bolts the the front cross bar (part that the horns bolt up to). Any place where the ducting touches an intercooler, radiator, or frame rail I have used foam in between to ensure everything is air tight and to also prevent wear from metal on metal rubbing.

The oil coolers were simple as the Setrab coolers have brackets with mounting holes at each corner. I simply bolted up the ducting to those locations. And like the other ducting, I have used foam at any contact point.

wow. the car looks really sharp. nice clean setup. well done.

This build has primarily been focused on suspension and cooling modifications. There are two areas with the engine that I needed to address. Fuel and exhaust.


Previously, I was running 850/1300cc injectors. While these provided more than enough fuel I have never been satisfied with the 850c primaries. I decided to pick up a new set of OEM 550cc's for the primaries and upgrade the secondaries to 1600cc's. Instead of using resistors for the secondaries I picked up a FJO injector driver.

Onto the pics:

Exhaust.

I decided to get rid of my old JIC canister style exhaust for something more quiet. I went with a Ganador Ti exhaust which I picked up from RX7Boutique. I also replaced my custom mid-pipe with an RX7Store resonated mid-pipe... The result was a significantly quieter car which was much more plesant to drive :) and im saving weight at the same time :icon_tup:

I also wrapped the down pipe and mid-pipe to reduce heat.

Wow, That's a really nice looking setup. You going to wrap back to the canister on the catback?

You will like the FJO. A word of advice on the install. Put a 10a inline fuse on the power wire of the FJO. It is typically wired into the ECU power for ease of installation. However, the EGI fuse is a 30a fuse. Though it will protect the ECU, the FJO is more sensitive.

Mine fried due to a bad alternator plug popping my EGI fuse. FJO would not reimburses me. Thought I would pass on the knowledge.

I had planned on it, but ran out of heat wrap... I will get around to it eventually.

Thanks for the tip! I had actually installed all this back in the Fall so I had it running for a while before I put the car down for the winter. I will definitely wire in a fuse before I drive it again in the spring.

Hey John, how did you attach the fiberglass adapter to the brake shield? Rivets?

Correct, it is riveted in place on the shield and it actually has one of the three mounting bolts passing through it to keep it nice and snug in place :nod::icon_tup:

Note: rivits not installed yet in this pic

Awesome, thanks for the additional pic. So did you have to take the hub off to mount the plate?

JhnRx7 02-20-11 08:58 PM

Update!

I have been collecting parts all winter, and now that it is starting to get warmer out Im really getting motivated to get the car back on the road.

My collection of parts courtesy Ray Crowe as well as my full SuperPro kit I got from allrotor :egrin:
http://farm6.static.flickr.com/5012/...47a5a17f_b.jpg

New tie rod ends to replace my old worn ones.

New pillow-balls and SuperPro's all pressed in with help from Scrubby Bubbles himself! :)

I also picked up a caliper rebuild kit from Ray :nod::icon_tup:

Original condition of my calipers:

Here is how bad my old inner LCA bushings were :blush:

Great work. How many miles on the chassis? What kind of grease did you use on the bushings?

Thanks. Chassis has about 105,000 miles. As for grease, I just used the standard white grease that was provided in the SuperPro kit. I have read that it is probably not the best, but I have a couple friends who have been running SuperPro bushings for years and have not complained of any noise or binding issues after using the supplied grease.

That's good to hear. Based on a tip from another member here, I went with the Energy Suspension grease - it's super tacky stuff, you can't get it off

Yzf-r1:

I had read about that grease in another thread. I would be interested to see how it works out for you, but we won't really know for a year or two :)

Gordon:

The job was really not nearly as hard as I had expected. Removing the rear suspension arms is a simple task which takes maybe 15 minutes per corner. The actual pressing of the bushings goes much faster if you have done it before or have help from someone who has. I had help from Scrub who has done a few sets and to complete all of the rear bushings including the diff carrier probably took us about 3 hours. Factor in some more time for cleaning and reassembly and the whole process can easily be done in a weekend assuming you have your own press.

yzf-r1 02-21-11 02:24 PM

I think it definitely helps to have to have two people to tackle this job (esepcially someone who has done it before), or just break it up to multiple weekends if you have the time

dvo 02-21-11 02:31 PM

everything looks great!

purerx7 02-26-11 10:30 AM

Car looks great John, glad you finally replaced that midpipe.

Thanks Brian. That midpipe was the very first thing I purchased for my FD when I got it up north haha



Update!


I got a care package from GoodfellaFD3S last week!
http://farm6.static.flickr.com/5054/...64a3fac0_b.jpg

IRP motor mounts, RE Speed filler neck, and a set of Rotary Performance toe links.


I spent 12 hours down in the garage yesterday wrenching on the FD trying to get everything back together....

All that is left to do is refill fluids in the motor, and install my midpipe and exhaust back on and I will be able to fire it up for the first time since November :egrin:

I love watching this build come together! I am so envious of it. Looking good John.
