I'd multiply the amount of money you want to prep it by 2.

Yes. As long as there's no alchy going in you're good.

At least. You're not counting all the suspension, wheels, tires, engine work, diff, weight loss, and other misc mods to get it "right"

With the Accelerated turbo kit you could hit ~400WHP on E85 with a pretty linear torque curve, running to a 8000RPM redline (65mph), 2500lbs easy.

Who has 15K to loan me so I can prep one for SM? (Who am I kidding, 25K)

Haha I would almost take you up on that one! But my wife would kill me.

I prepped a marginally competitive SM car back in like 03-04, I know what needs to be done to the car. I'm not budgeting for breaking the motor a couple times or wear items like tires. And even 20K would be on a budget, no triple-adjustable Motons or anything like that.

But I think it's a great starting platform for a SM car. With just removing the junk from the trunk and 1/4 tank of gas the car is around 2640lbs and I can think of at least 100lbs more which could be dropped without any real effort. The minimum weight would be 2480 with a turbo and 275 tires. I don't think even with the turbo component weight it would be difficult to hit that. Fitting 275s on the car isn't an issue.

Of course once you factor in the cost of the car, it would be a lot cheaper to find an old Evo and run that. But hey maybe 3-5 years down the line, if SM is still around.

Where is the 4-seater version? Not sure how this car wouldn't be in SSM.

The BRZ has a back seat. Not usable by anything but small children or very small adults, but it exists with seatbelts so it is SM legal.

SM build is slowly coming together! Gonna go into SM t2(street tire class) next season.
I'd say I have about a $3000 budget until next season starts.
I have 17x9.5 +38 rpf1s gold coming in from the group buy this December.
Can't wait!!

So this is a dyno plot of a BRZ with Crawford's turbo kit versus a GT30R STi kit. The BRZ is the one making a lot more torque. In fact in another post they show it's making 250lb-ft at 2200 RPM at 5 PSI. The speculation is this is being done with a twin-scroll turbo and a built block, but still a 2L displacement. They haven't really released many details. Would be a hoot to drive in SM, but might be a little hard to control.

Looks like an evo dyno plot.



...ok granted an evo doesn't weigh 2500lbs (or whatever).

Im pretty sure its because the brz/fr-s heads and intake manifold runners are HUGE! Way bigger than big port jdm heads. Also direct injection helps.

Yeah it's just a more efficient setup. The dyno plot above was done with a VF37 turbo and a built block, I'm not sure if it was still 12.5:1 CR or not. They eventually made right around 475lb-ft peak, but that's not at the wheels so around 380 ATW (20% loss or so). That's still plenty for SM in a 2500lb car. So tempting but like I said the wife would kill me.

My wife is so happy I got rid of Godzilla--she's given me clearance on a hairdryer kit for the FR-S. I want to run it in STX in '13--but oh, the temptation to just do it NOW! lol

Quick question... Does a TD04 19T upgrade put you into SM class on a 2005 WRX? Buddy of mine is trying to figure out his class.

I am in SM with a 2002 WRX because of a VF43- (wish I just protuned my TD04 now!) but I was wondering about the 19T since its the same turbo as stock- just modified...

Thanks!

I would say the opposite. Why not get all the gains of SM with only a .001 sacrifice over the ASP guys.

Yes. Unless the turbo is totally stock, it's SM and beyond.

^ Thanks I was thinking it would be SM. What about P&P on a stock turbo? Does that modification bump to SM even though all stock hardware is still present?

Yes, that also bumps. The rules are free to download from the scca website in a nice PDF.

The problem is no one has really done a "to the limit" SM build on an STi. Cams and bigger turbo's tend to move the power band to places that aren't as friendly for autox. If you do it right, then yes, you'll be faster than ASP. The real problem is the ASP guys have had a lot of time to develop their cars and they don't have any option to change out other parts. When you have a set part to begin with, it makes the equation a lot easier to deal with.

This is more or less how I look at it, with a sprinkling of my thoughts above. ASP is very fast nationally, and SM has fallen for a few years so the 2013 PAX is just a reflection of that. At the local level I think it'll be hilarious to try and explain how the regular ASP guys should be as quick as SM cars
