Aren't your fingers numb for typing all them goodies wisely chosen? IMO, I would just state "I put in $**tload into the FC" to make it simpler and less strain to your fingers! Great choices, btw!

I want to try Jacob plug wires next!

-8AN feed & -4AN return! Sure sound like you don't anticipate fuel deprivation to your injectors. My setup is -6AN feed -4AN return, good 'nough for my app.

Interior upgrades I have chosen; Personal steering wheel and Nardi mahogany for a special occasion, I have chosen VDO mech gauges.

So, did you swap diff mount? That's the only ones I didn't swap... one day.... one day heh

Awesome choice of arsenal, if I may say so, BoostedFC!

[BoostedFC]

I want to do all poly mounts eventually. I almost got a Nardi wheel. I'm really thinking about painting the car black, re-doing the wheels in gold & have the lips black chromed. I actually want a more classy look. I need to find a set of buckets in bad shape, so I can have them reupholstered in black leather with gold stitching along with the shift boot & e-brake.

[1stGenNa4Now]

Sounds like a crazy rx7 Is it fast? It takes a little more tunning with fuel injection am sure. Top speed redline?

[black rocket]

I'm trying the best to have a stock look, exception to an air intake slot I fashioned at upper bumper. Black is nice but 5 min of gratification after detailing is always disappointing...

[BoostedFC]

Etimated power somewhere around 340 before the 150 shot of nitrous. Top speed well not sure how accurate the speedo is, but 150 mph was where I let out. Never have had the car above 8200 rpm. This car is not for speed, but more just so I can say I did it kind of thing. It holds it's own when need be. This car has power steering, AC, full interior & a bunch of stereo stuff. I actually most the car was done back in 1999, it was considered pretty quick then LOL. I need to get my turbo car done when I get another job. I'm shooting for lower 600 hp in a stripped & gutted 88. Trying to stay competitive with a couple of my friends & thier 650+ awd's

[BoostedFC]

Have been screwing around in the garage over the past week or so. I have been taking down some measurements so make a small lip for the front, a set of side steps & do a rear diffuser set up for the Mariah. I'm also waiting on a friend to bring me two different brake set ups to see if I can maybe adapt them to my FC. One set is Baer & the other is Wilwood, I'm thinking my real problems will be finding the right rotors. We will see soon I guess.

[project7]

Good luck with the brakes, I'll be watching to see what you do there. So far, my best course of action is a set of Powerslots out front with stock fronts on the rear, no clue which calipers yet though.

Quick q about the hood, did you do that out of preference or was there no other option? I'm thinking if I run into clearance issues with my setup(which I'm almost positive I will) that I'll try moving the scoop from one side of the hood to the other.

[BoostedFC]

Were you planing on supercharging or turbo charging? I had no issues with clearance under the hood with the supercharger kit until I decided to alter things & add components of my own. This hood will be swapped back to my turbo car & the hole will be patched. I plan on making a cowl type hood similar to the newer GT500

As far as the brakes go the stock 4 pistons up front are nice, I'm just fiddling around. I plan on using the factory front 4 pistons on the rear with larger rotors like Higgi from another forum & one of the two caliper set ups from above. I may just do the Evo brake swap, not exactly sure at this point.

I have a few plans other then the exterior & brakes I also need to attend to (interior)

[project7]

I'm blown with a Camden and a Holley 650 up top. I saw your fi setup and I'm curious about it because it sounds like you're making more power than I'm hoping for, by quite a margin.. That hood will look pretty awesome with the Mode 6, can't wait to see it!

[BoostedFC]

Do you have the 5" or 7" Camden, how much boost, what motor, what port job & are you running any kind of charge cooling? What kinda of numbers were you looking to make, I have spoken with guys that made in the 250 range. I could never get any specifics on their set ups though except they were running around 10psi, but don't quote me on that for I'm not too sure. Also I have only estimates on my own power 340 is a goal & should be attainable since I have seen an all out set up right at 300 in the past with a carb

[project7]

Don't quote me on this but I think its an s5 t2 block with n/a rotors, fairly large street port, unsure blower size or boost yet.. Bought the engine as is but it is newly built.. I didn't dictate the specifics. I've plans for a meth injection setup and no charge cooling currently though I really want to. What did you do for yours? I haven't seen any specifics from anyone running a blown rotary and this is my first boosted application.. I'm on the wrong side of clueless..

[black rocket]

According to the set-up you have you are running 9.4:1 compression rather than normally applied lower compression TII rotor of 8.4:1 ideally for forced induction application.

This particular set-up, as you mention, will be squirting methonol/mix basically to cool occurrence of detonation heat using pump gas.

Have you thought the set up thoroughly as when, not if, your meth pump or nozzle fail as you'd be squirting at every boost (turbo) constantly with s/c? Just curious.

[project7]

Well, like I mentioned, I got the engine as-is. I could maybe shoot for some t2 rotors but that is kind of a big set back if it becomes a requirement. I mean, is detonation a guarantee if I'm running slightly higher compression? You'll have to pardon ignorance, like I said, this is my first foray into the world of boost, and rotary engines in general.

[BoostedFC]

Well on the compression NA could mean different ratios depending on what yr rotors you are using. I am using the 9.4:1 from a S3 13b, then you have the 9.4:1 S4 rotors which are slightly heavier then the S3 & S5 rotors & lastly the S5 rotors are 9.7:1. For the turbo rotors the are 8.5:1 for the early models & 9.0:1 for the later. Running higher compression does not mean failure, it means tuning has to be more spot on & the use of higher octanes. As for the blower measure the case in between the end plates (ribbed section) it will be 5" or 7". My set up has a water to air aftercooler for charge cooling, smallest blower pulley Camden offered, larger diameter main pulley, port matched the manifold & a bigger fuel system then most of what I seen guys running on the Camden. I do have an Aquamist water injection system, but it has been taken off & may not go back on.

[black rocket]

tuning aspects, yes indeed otherwise you will be facing serious damage to your engine.

[BoostedFC]

When it comes to higher compression ratios & boost or nitrous the need of a quality tune is key. The RX8 has a factory compression ratio of 10.0:1 & with moderate boost levels they do fine. I know of piston motor guys that run high compression motors on boost as well, it's just more common to drop the compression & raise the boost to make more power allowing for more tuning error to a degree. They generally run high octane fuels or meth injection.

[project7]

I'll have to measure the blower when I go back down to the car. It is about 2 hours away, but I'm hoping to get down to it sometime in the coming week. I'm fairly certain the rotors are from an S4 block.

So Boosted, why are you thinking about leaving the water injection off? I was suggested the meth injection from a guy with a very similar setup to mine on the club forums. I'm really interested in your aftercooler setup, it's something I want to do but I'm not at all sure where to begin on that.

I do plan to ensure proper tuning before I'm finished with this thing, but I am planning to daily drive it for a little while and I'm kind of concerned with it being a carburetor application, the tune can vary depending on the weather.. I'm thinking a swap to efi may be in order but it will be sometime down the road so that means the carburetor is going to have to suffice for a bit, at any rate.

[BoostedFC]

I just have too much going on in there at the moment & the aftercooler should be fine by it's self. Before the cooler I was dependent on the chemical cooling. I get a lot of my ideas for things on my car from the V8 drag racers, an old friend of mine who built old school drag cars had a 468ci with a 8-71 blower. One day I was poking around in the shop & I noticed there was a large aluminum piece mounted between the blower & the manifold, it had hoses running to it. I asked him what it was & he told me it was an aftercooler made by Superchillers. After that I was determined to get one, so I took some measurements, drew up a few pics & sent them to a shop recommended to me by a friend. The cooler system consist of the cooler, pump, hoses & radiator with electric fan for the cooler. I'm going to have another friend add some small tanks to pack ice in for the track. My cooler is the reason why things don't fit under the hood anymore, but it's fine (function over looks)

[project7]

Do you feel that a more traditional intercooler would be as effective? I ask that because I am half-tempted to try rigging up a top mount from a t2. I've already got the hood, but not sure how much room I'm going to have to play with once it closes.. Probably not much, but possibly enough?

I'd love to see some pictures of your engine if you have any.

[black rocket]

I personally not a fan of TMIC only because of heat source being right underneath. FMIC, if mounted properly it will give it a chance to cool forced air in spite of catch on road heat.

Chargecooler, on the other hand has steady cooling effect and, thus much higher in price.

[BoostedFC]

Yes you could actually run a air to air intercooler if you feel like running a shit ton of piping. I'll see if I can find some engine bay pics, everyone wants my secrets! LOL

[BoostedFC]

Well here is a pic. Things are apart & out of the car right now, but the basic idea is clear.

A mess!

[black rocket]

Nice wiring! ...and plumbing and everything else! I always catch myself trying to view beyond the frame to see further... I hate that.

[BoostedFC]

I am in the process of doing a wire tuck & delete.

[BoostedFC]

So today I decided to start my initial tear down. I pulled the power steering, A/C pieces & intake manifold, blower throttle body ect. The car has been down for some time now so I have also decided to pull the motor for a rebuild & new porting. The idea is to clean things up in the engine bay & freshen up the motor. The power steering & A/C will not be going back in, considering that I never really drove the car all that much & don't plan on changing that. Basically just a weekend car during the summer. Next weekend I plan on pulling the motor to set aside till I get the rebuild kit. I most likely will start pulling the interior & stripping down the paint on the car. This will be a slow process as there is other things in everyday life in which come first. I will update things as I go & try to get pics up.

[black rocket]

That sounds nice. Work on cars while dealing with everyday life... what a concept!

[BoostedFC]

I need to go buy a bench grinder with a buffing wheel. I might polish up some of the dull parts.

[project7]

Good stuff. What strut tower bar is that?

[BoostedFC]

The front is an Autobacs strut tower bar.

[BoostedFC]

Well the search for a non power steering rack is on. I have been tossing this idea around for some time now & I figured I would get rid of the PS & AC since they are not really needed.

[shannonspeelman1231]

man i hope its runnin when i get to va its so pretty man its just an awesome car i hope my turns out that good
