$2004 GRM challange, building an FC

some guy gave me an 86 with an 88 TII motor in it. car is in great shape except the guy tried to rewire the 86 harness to make it work with the TII motor. its a complete mess, but a good starting point.

anyway i need advise and some parts. advise first, i need to come up with an autox suspension setup thats fairly cheap, but it also needs to last after the competition as the car will most likely see more track then autox afterwards. im thinking koni/gc with 275/400 rates, but thats big money. anyone have a set used? also need sways, thinking about the eibach bars. i would most likely make some camber plates to save money, hows the stock caster on the FC? should i make camber/caster or just camber?

also how is the gen2 PS rack when converted to manual? is it too hard to steer? consider the car will be completely gutted, so it should be a few hundred pounds lighter then stock.

how hard is it to remove all the emissions stuff from the car? does the ECU care? what about the exhaust gas temp sensor, is it even the least bit accurate? could i use it to tune at all?

right now these are the big items i need:
TII aluminum hood (maroon or black)
88 TII engine wiring harness (both sides are trashed).

if anyone local to ATL has any of these parts and wants to sell them to me at a good price (keep in mind i can only spend 2004 bucks for the entire car) lemmie know, ill let you autox it when its done.

There is a noticable difference between a Manual rack and a rack that just had the PS ripped out, my fried just did it and its waay harder than the TII he drives with a manual rack, i suguest swaping them

the ecu doesnt care about most of the crap you rip off,

smog pump
most of the solonids
ACV etc

Did you get this car from someone on the Solo2 list?

A set of KYB AGX can be had for less than $400 new + GC spings a threaded perches $300 set. Sell everything you rip out and buy good tires.
275lb springs might be too soft in the rear for autox, those look like road race rates, I'd go up another 75lbs.
Good luck

the body is decent, a few dings but nothing bad. chassis is clean except for one spot below the battery is fairly rusted. should be easy to fix. everything seems to be there. the lower half of the intake manifold is trashed but i think i have one laying around that will fit. the injectors are trashed too, will most likely have to get new ones. other then that its pretty nice. ill be bringing it to some atl region autoxes once its back together...

Good luck, tell me how you do.

Been there, done that. It is FUN! We got 3rd place out of 59 cars. Our car was pretty fast in both auto-x and drags but last year the stakes were raised SERIOUSLY with the fastest cars running 11s!

so they give you a year to build the car, or can you use one you've already started on and built to the rules that you know at the time and then change it according to new rules?

woah man, that car is nice! how did it do on the concourse? im going to completely strip the interior and paint it gray, prolly the same with the engine bay. thats alot of damn polishing work too. looks nice, i am dreading that part.

the bad part about my car is the dash is in pretty sad shape. all of the nice plastic trim pieces just fell apart when i was taking them off. i do plan on making a little aluminum plate to house some switches and gauges (got some pretty trick ideas, hopefully they will work). if i have some money left over after im happy with the performance ill go junkyard hopping.

what did that car run in the 1/4?

there really arent too many rules. you can do whatever you want to the car, but you can only spend 2004 bucks. the car must be roadworthy and you cant remove body panels, thats really it.

oh yeah, whats with the dual belts for the alternator and water pump? i was thinking about removing one of the belts and chopping off the back side of all the pullys. is that a bad idea?

3rd place in the Concours.

[email protected] in the drags.

5th place in the auto-x. It was raining for the auto-x, we could have placed better if it was dry. We couldn't use our power on the course, we were the fastest front engine-RWD car there. 3 AWD cars beat us and one MR2 in the auto-x.

Dual belts on the alt help keep the water pump from slipping. Do a search and you can find the Dodge Caravan part number for the pulley, it is cheap.

My teammate did all the polishing, that was the most time consuming part of the project. The interior was stripped underneath the carpet, the dash was just a shell. Power windows and sunroof remained. No PS with PS rack, not recommended for auto-x IMHO, we did it and it was a bitch to steer on the course. For street it was fine.

The car weighed 2450lbs for the drags, 2500lbs for auto-x.

i think i will try to get a manual rack. my friend has a miata we are converting to Spec Miata and we took out the PS pump and its a bitch to drive around, great ratio for the track tho.

anyone have onna those in ATL?

jeff i was expecting to go a bit faster then that in the 1/4. i have heard rumors of 12's with the stock 13b and turbo, but i have been messing with 2nd gens for all of a week now and have never actually driven one, so i dont really have a clue.

I'd suggest leaving the PS as-is also.

Russ,

Yeah it seems with a 105.5mph trap speed we should have had a faster ET. On our fastest run the 60 time was 1.97 sec. I can't figure it out. If we had some $$ we could have gone faster with drag slicks, the TII diff is pretty stout. The TII diff mount isn't though, our rear subframe broke a few hundred miles after the event. Becareful with that.

All we did to the motor was a cone filter, full exhaust with 3" straight pipe off the back. Using a HP calculator based on ET we had 220rwhp, based on trap speed we had 240rwhp.

Figure ~16% drivetrain loss that was somewhere around 255-278hp at the crank. Not bad considering stock is 182hp. We ran 9psi boost, we had enough fuel for 10psi. In testing we ran 12psi but it was cold (35F) and the a/f ratio we to 13-14:1. Man the car pulled hard at 12psi.

Of course there are lots of people who show up expecting to go a lot faster than they actually do. Based on G-tech testing we would have been happy with a 13.5 which was our goal.

A guy I know from Detroit is bringing down a 10th anniversery RX-7 with a stroked 5.0 in it. I just wanted to give you a heads up as to what you will be against.

You will always see interesting things at the Challenge. I've put our Big Orange into retirement from the 03 Challenge and am going to bring some mutt of an FC for 04...we shall see what happens. Either way, it's tons of fun.

I love the challenge, it's a great event which i would love to do sometime, I'd probably do an omni though. My brother is obsessed with those things and i believe the local area auto-x champ won the challenge one year with one of his omnis. impressive car to say the least.
