Struts

One other thing. You should really consider doing the Koni/GC setup in this car. It really improves (transforms) the handling of the SVX. A good time to do it would have been when you had to replace one of the struts.

And a bigger all aluminum radiator.
Removal of the 5 fan relays alone is worth 1/3 of an ounce.

Thanks guys,

I'll try and answer the questions.

1) Transmission - the 6MT will be in my hot little hands next week.

2) Shocks - definitely getting upgraded. Using DMS which are upside down, 50mm Bilstein-based coilovers. Fully adjustable (16 clicks of bump and 4 clicks of rebound).

3) Engine - the maths I've done says the EG33, with cams, compression and an standalone ECU, should get past 300hp. With some aggressive porting and flow work and more revs (9000rpm) it would get closer to 350hp, maybe more. The engine has 240hp stock...that's a pretty big base to start from.

I worked out I can virtually remove the bumper support, and just run the inner liner...it might mean we shouldn't lean on the bumper too much, but it will be fine.

My last rally car, a Celica GT4 (all trac to you I think), had 200hp at all 4 wheels, and weighed more than 3000lbs. I won a few rallies with it, so if the SVX can get to 3000lbs in rally trim, and have more than 200hp at the wheels, we'll be on a winner.

It sounds like you are on the right track. I don't know what to tell you as far as better cams, but engine management and slightly more fuel will definitely brighten up the engine. If your going to go through all of that expensive engine work, you might want to just slap in a turbo instead. That is what most race folks are doing with this engine hear in the states. The dune buggy guy I spoke with said the engine held up very well.

As far as winning races, it sounds like you could do that with the stock engine and all the other mods. A lot of that is the driver. You will be suprized at how this car responds to some stiff struts and springs. Really transforms it. I have never cornered like I have with my SVX with the Konis turned all the way up. A little hard on the but though.

Keep us posted.

Chuck,

My rules don't allow turbos. I have to keep the stock manifolds, but virtually everything else is free. Thank goodness the SVX came with twin 60mm throttle bodies.

The shocks I've run in th past are pretty firm. You usually can't bounce the car when you lean on it, it's rock solid, but at 80mph on the dirt, between the trees, it rides like a sports car.

Well in that case, it will be really interesting to see what you come up with. I think your goals are realistic.

Matt,
Is there a way to test if the brakes will stand the pain after you remove the dust plate. I will be real interested to see how much of the problems we get with SVX brakes are related to the cool.

We don't have any bumper supports on ours. It sags a bit but strap ties will hold it up. Besides it makes it easy to remove when you snag it. You'll be hard pressed to be under 3000 but maybe 3100 is a decent spot without a driver and co-driver.

As for the cams, every engine builder I've talked to says do that absolutely last, up the compression first.

Definately going the right way on struts. Don't waste your money on the koni's as they aren't a good set up for harsh punishment. Street and track days they're okay but they aren't for a race car let alone a rally car. How much did that cage end up costing you? Ours is set for this winter.

The people on this board seem to have some very good succses with getting diffrent cams to shift tghe power band up alittle, and getting the stage 2 ecutune ECU so the engine can aculy read the amount of air that is coming into it at those RPMs.

Bill,

I've attached pictures of the towbar. Including the Hayman Reese part number. Not sure if it's still available.

So I hacked out the middle section of the bumper support. Probably only saved me about 8kg, but it's worth it. I left the foam in there, and surprising there's a more traditional bumper support panel (for other JDM Subaru's) sitting on top of the heavy US crash one. So I left each end of the US crash support panel there, and bolted it to the JDM part...should be good. (Note to self, take more photos to explain my work).

Tony, I'm not sure how we'll be testing that. From my perspective, I know there'll be problems if the brakes fade. If they don't, then I'm not so worried.

Brakes setup is proposed to be 4 pot WRX calipers at the front, with the rotors machined down to size, and possibly the 2 pot WRX calipers at the rear with a vented disc (instead of the standard solid disc)*. Backing plates will be removed to assist cooling and Ferodo DS3000 pads fitted.

*Unsure if this will work of course.

Painting the cage has begun.

Matt you shouldn't have any braking issues at 3000lbs using standard SVX brakes aside from too much braking in the front and the need for a proportioning valve to keep the rear end stable.

Did you read what I said? I said engine builder meaning building an engine not just a portion of an engine. You don't get 300hp out of computers and cams. Hence the reason why we haven't changed cams yet plus computer chipping is a no-no for non-ricer classes.

Matt,
Thanks! Can you take a picture of where the hitch actually bolted into the SVX's frame?
