totally can see this. i was almost thinking the OP should use a larger custom size griffen unit. they make custom size radiators for NASCAR and other odd shaped custom apps. like you have pointed out. he'll need more than these import specific direct fit units can support. heat is such a bitch with these.

personally, i'm just like you. stock ITR engine-drivetrain with a 2.5" modded edelbrock header. no heat issues or problems breaking axles or trannies.

before the OP makes any alterations to his setup he needs to look up or contact the member (zygspeed) on HT. the guy has a full track assault built turbo charged ITR, and the car is disgusting to say the least!

one point that is certain is the turbo in the OP setup is too large for the power band desired on a track (road course). IMO a gt28rs is the perfect insta-spool turbo to have for a b series honda that is being built to raise hell on a road course.

cooling is going to be your biggest problem, so be prepared to get a nice radiator, nice fans (spal) and maybe invest in some heat wrap or thermal coatings on the DP and exhaust housing (like swain tech's white lightning coating).

just some ideas...

crish rado turned his drag scion into a road race car by adding a huge front spoiler and other things

thanks for mis-information, they are not even close to the same car.

I can't make any comments about the specific setup, but the na civics and crx's that I run with will kick my *** all day long. I drive an '04 WRX in STX and I can't come anywhere close to the times they can put down. Much of it is the driver but it does have something to do with the 10" wide R-Comps they are rocking.


On the other end of the spectrum, I had the opportunity to see a 90's BMW M3 that was turbo'd on a road course and on an autocross track. He had a monster turbo and was only able to get into the boost on a couple places on the autocross track, even though it was a relatively open design. I believe he was much happier with the performance on the road course.

No matter what you do, racing is just to darn specialized.

Ken, why don't you have the best of both worlds! Save the 2000 Si the way it is for the 1/4 mile or 1/8 mile on some events that'll be held in the near future. And get yourself another car or shell and built it for ONLY the Circuit, you know what I mean. So, if there's an event for the 1/4 mile you could take your Si, and if there's an event for Time Attack, AutoX, etc., then you can take your Road Race car.

listen to this guy if you think non boosted is boring on track.

actually just build a decent N/A motor if you REALLY need power on track. this guys da is a BLAST to drive on track(and was pretty fkn fast at expo9 n/a).

Only problem with this suggestion is that Ed hasn't finished the car, let alone tracked it. Not that I doubt his planning, but that doesn't show tested and proven effectiveness.

I'm guessing you just aren't aware, but as someone else said they are two completely different cars. The time attack car was built specifically for that, not changed from the drag car.

I don't want to come off as critical, but what exactly the heck does this have to do with the OPs situation? Your WRX is getting beaten in STX because it handles like poop in comparison. That is only made worse if they're running Hoosiers and you're running street tires. Please keep in mind the actual question when responding to a post.

As others have mentioned, the biggest hurdle in a turbo track car is dealing with heat. You'll need to go to extremes to handle it, so be prepared for that. The second biggest hurdle is going through expendables, also as mentioned (brakes, axles, etc). What that means is: beef stuff up appropriately (stock Civic brakes won't do the job as one example), and bring spares.

It really is something you should research before jumping into (which is exactly what you're doing, so !). As a beginner, the suggestion to swap out your turbo stuff for an NA engine is a GREAT one. It is always a personal choice, but if you want to make yourself faster, ditching the turbo is the way to make that happen in the quickest way possible. The power of the turbo stuff will hinder that learning process. If you have the means, you could always keep that turbo engine in the garage for a year or two from now, when you actually will know what you're doing.

Aside from all that, you'll need to realign your ideas on the kind of power that makes a track car fast as compared to what makes a drag car fast. Don is putting down ~300whp, and is a friggin' monster. He also has the experience to control the car. More than that is really just silly, and would need A LOT of work just to put the power down.

EDIT: Also, all the suspension talk is not entirely necessary FOR THIS TOPIC. You'll be fine on what you have for the time being, though it's not ideal. No matter what, it has very little to do with your engine setup for now. Someone (Don?) suggested an LSD, which would be 10000% more important than different shocks, springs, or swaybars when related directly to a turbo.

Good Info. This is something Im looking into at the moment, and I already know the turbo kit would have to go, as I would prob kill myself with 450+whp on a track

More seat time is what Im seeking.. drag racing just happens too fast..
