ATTN: Older Chassis with complete Sti swaps
Do any of you guys / gals autocross? After examining the latest results of the SoloII Nationals, I was left wishing there were a few Subies in the Street Modified category. It appears from the pictures taken during the event that it was rather wet at Nationals this year, and an all wheel drive setup would lend itself nicely to the weather experienced at the event. Sure there were plenty of WRXs and EVOs participating at Nationals, but I would think this particular class would be an excellent place for all of you people running around in the older 2.5 RS style chassis with full Sti swaps.
Most of you running around in these cars already have a large list of the mods as well as programmable E.M. to support them. Procure some dyno time and build a good tune for quick spool on high octane and that�d be all you�d need. (Other than driver skill and one or two sets of wide race rubber on appropriately sized wheels)
If I had one of your cars, I�d take it to Nationals in a heartbeat. This setup driven well could really turn that class upside down. :devil: Just a thought.
Edit Note: I'd like to see some people who own these cars to start competing in SoloII and go to Nationals with them. Considering the potential power to weight ratio, potential grip provided by the awd and ability to accept some reasonably wide rubber, and the fact that there are a lot of ways to lighten the car that Street Modified allows, it could all add up to some serious fun.

It's this new thing that Subaru invented with the inception of the brand new 2005 and 2006 STI the fastest tubro charg3d subAru's ever brought over here stateside!
You drive around a parking lot with cones, but don't hit them utherwise you'll be penisalized! :eek:
Maybe he's talking about swapping cars with somebody who has a faster or older one? :confused:

I tried to include a link in this post, but I haven't posted enough to be allowed to do this yet.
Sort of like drag racing for those who like to turn and brake as well. :) (Not trying to annoy any drag racers here. That's not what this thread is about. :p ) It's parking lot racing through a technical cone course for times. Cars are classed according to the modifications done to the vehicle. Cars compete for time against the rest of their class, running basically 1 car at a time. That's the down and dirty of the sport...
Cheers

hmmmmmmmm interesting stuff... but the 1/4 mile is all that really matters to me. No harm done though. :)

So how do you do the swap without illegally changing or modifying the front cross member? I haven't found an allowance yet to change the cross member and I haven't investigated how to do the swap without changing it. I guess I'm just lazy.

My crossmember met the big hammer. It's one of those "minor notching, clearancing, etc" things. The other option is run the stock NA crossmember and do a custom uppipe/header setup that routes the pipe like most RS turbokits do.
Honestly I'd rather run a supercharger if I had to design the car over again, which would negate all of that. However I'm going to run the car with the turbo setup next year at least.
As far as ballast, the gas tank in this car has some issues with fuel starvation, so most of the ballast is going to be gas in the tank. We'll see how much is leftover to play with after that.

Phil:
I am actually thinking about doing something similar long term and I am glad you are getting yours together. Can you go into a little more detail about your setup? I love the oil cooler where a TMIC sits. What is your goal for hp/tq and are you going to use antilag or just a small enough turbo to help power out of slow corners? What ecu are you using and how much of a pain is it to hook up all the wiring. If I did it I would want to go with a full standalone like the hydra to avoid the hassles of the stock wiring harness.
Good luck getting it together and I hope your garage is heated if you plan to work on it in a Wisconsin winter.

omg rofl ... great laugh after a long day of work! I had tears in my eyes. thanks guys. You're bastards ... but funny ones!
btw. I promised I wasn't going to change anything anymore for a long time. I was just going to concentrate on driving. Well times up ... it's been something like two weeks! I had a 2nd place last Sunday ... so, I'm getting the struts revalved, and then experimenting with extreme ride heights and bigger front sway bar.
btw. I converted my Suby to 2 wheel drive ... that would be Left Hand Drive:

That's an air/water intercooler, and the thing in the front is the radiator for it. There is a 1.5 gallon resevoir in the trunk as well. I'm using a TD06-20G turbo on the car right now. I'm using a WRX PnP Hydra ECU w/AVCS support. I ended up building my own wiring harness using just the plugs from a JDM V7 full harness. Wiring was time consuming, but not all that difficult. The car should make 400/400 whp/wtq pretty easily, depending on the dyno of course. It will only run on C16 gas. It's a 8.8:1 CR built EJ257 w/V8 RA heads and DPR cams.
That picture was taken in my garage (which is heated), I'll be okay. :)
Storm: Haha yeah I tried to take it in for a bad wheel bearing and they looked at me funny!

i heard another interpretation of this rule last weekend that if the replacement cross member used the same attachment points it was still legal???

| dwx | 10-28-2005 12:22 PM |
It's a gray area imho. Given the current state of SM and the guys that run it, even nationally, I don't think someone would protest a swapped crossmember. The one suspension attachment point on the crossmember is identical on all Imprezas. Under the letter of the rule however, it would be deemed illegal.
| speedyHAM | 10-28-2005 08:00 PM |
The large hammer method is the only way to make it 100% legal. You probably wouldn't get protested as dwx states, but why take a chance.

Right now I'm running the stock '98 EJ25 manifold with custom up/down pipes. It seems to provide a slightly better spool time compared to guys using turbo plumbing for some reason... probably because it's a little less convoluted. It also sounds different (better) than all the STi's I've heard :)
I stuck with the R160 housing with a quaiffe in it. The housing weighs less than the R180. The R160 hubs are also lighter... less un-sprung weight. The quaiffe will hold up to whatever I can throw at it. I've only broken 2 rear axles but those were entirely my fault (all wheel drive burnouts in second gear).
Right now with a half tank of fuel the car tips the scales at about 2750 with the cage. It still has A/C and all the power accessories. Lightweight bumper beams are definately in the near future.
DWX, are you using a spearco 2-230 air/water core? I've got the 2-231 one in mine but am looking at going bigger.
Car hasn't been on a dyno yet as I'm still getting the hydra dialed in but if I did my math right the car should put down about 360-380 on pump gas.
Right now the nut behind the wheel is need of serious upgrade to keep up with the rest of the car. Once I'm ready to start spending real money on tires to stay competitive there is an aerosim carbon widebody kit with my name on it. Should be able to run 285's under the fenders... then we'll see.

The core I have was made by Bell intercoolers, I got it from Chad Block as he had it made for the kit he is building.
Lightweight beams are not legal. I do have front and rear beams for my car and they would save 58 lbs of weight off the car. If I ever prepare the car for XP (they just renamed the new AP class to XP) I'll put them on.
I couldn't do much more in SM to either lose weight or modify the car. Custom control arms/knuckles are about the only thing I would like to do, but it's expensive.

The '98 manifold bolted right up with no headache.
I would have thought the lightweight beams would have been legal. They kinda made it sound like any bodywork/attachment points ahead of the vertical plane of the front suspension was pretty open. Oh well. Anybody know if the type RA glass is DOT legal?

I have a swap, locally it could easily dominate SM as it sets, even divisionally... but to truely make it nationally competitive, I couldn't drive it to work every day comfortably.
SM tends to always set FTD for fendered entrants and that isn't any small accomplishment. SM is probablly the worst place to run unless your budget is open ended.
Sure it may do well, but I'd rather run a 2.5 RS in STS or a WRX in STX or something with someone at nationals than end up in SM. Just my $0.02 Thought has crossed my mind to give it a try, but it just isn't reasonable at this time.
