on page 90 of the 2005 solo rules for prepared classes it says intake manifolds are unresticted. I am running a 96 gsr in dsp. Can i run a type r style intake manifold?Considering it's single stage I will have to do something to the ecu so it doesent try to open the butterfly's in the dual stage intake (that part i will figure out). I am just surprised because the other cars in my class seem to be running stock intake manifolds.

 

"intake manifolds are unresticted"

You can use whatever you want as long as it doesn't violate any other rules (which would be hard to do). It's not super common to see people run something different (ITBs for example) becaue of the cost vs. benefit.

 

do you think it's worth it?

 

After all other worthwhile modifications are made it becomes "worth it" at some point.

 

but to stay in dsp the allowed mods are limited. I plan on port matching whatever intake i decide on and my exhaust plus a mild head porting. I have not decided on overbore pistons yet. I will have the head milled a bit, seems to be the only legal way to increase compression in dsp.

If you don't have your tires and suspension dialed in all that work will make your car marginally faster if any at all.

fixed it fer ya!

 

It says the intake manifolds are unrestricted, so people change to ITB's. What about changing throttle bodies? I don't see why it would be illegal, seeing how ITB's is essentially removing the stock throttle body.

 

Yes a larger TB is legal. Lots of places sell them, but I have never seen any real tuning info on the GSR motor with the limitations of SP. Any of the info I've seen includes cams, pistons, etc that are illegal, therefore the tuning info is basically useless. The possible increases are all going to be fairly small compared to driver, suspension, tire improvements and weight reduction. You may also want to wait until next year when all the 94-01's will be on the same line. Maybe they will also move the Bimmers out and give the also-rans a chance. If that happens, there is a much better chance of serious development being done by nationally competitive people.

 

I would have put the 90-01 NOC's on the same line instead of 94-01 and 86-93. Hell, since the Type-R is on there, it should just be 90-01 Integra on one line and 86-90 Integra on the other line.

 

Heh, it is kinda funny you bring that up since at the ASCC meeting tonight there was discussion about how that Focus running in DSP has multiple illegal parts.

 

Focus? I'm from WA. I think you've got the wrong dude.

 

Not you, the topic starter.

Although that is true Nate I was trying to make the point that when setting up a car, more power doesn't do you any good if you can't get it to the ground. I could have gone further and say it does no good to get it to the ground if the driver can't control it.

There really isn't any specific tuning info because the rules clearly spell out what you can do. You simply build an engine to the limit of the rules.

Also, I know there are several national trophy/champion DSP cars that could be considered "underprepared" as far as the engine work goes.

Double check the rules. IIRC, that is not legal in DSP. You are limited to FSM authorized valve jobs and port matching (which you already listed, so I assume you meant additional porting).

H-T ***** can lick my ***** for all I care

 

you mean Nates focus, he told me he was running one of those e-ram leaf blower super chargers. In the back of my mind i knew it was ilegal but didn't seem to care considering i have ben running faster times than him.

 

suspension is as dialed as i can get it imo, the quaiffe lsd is in and kicking ***, i am running A3S04's. Just looking for some suggestions on dsp legal engine tuning for my b18c1. I have been running very well imo, i had first place this week until the last round when the impreza just slipped by me, oh well second is better than third.
