little things to improve performance

[LOK[R9]]

I guys .. i'm starting racing (circuit not drag) with my car and what to know little things to do to boost performance. Anything!! Just remember i keep the same engine (D15B7) and just want to fine tune it to run smoothly on the track.

thx for all the suggestions

from what i've seen in other posts.....you're gonna get people to come here and say to do a swap with a B18 series engine. actually, if you search, i remember reading a thread where two guys were going at it cuz one said that he tricked out a D series engine that could blow away and B series.....i just read it cuz it was funny seeing both guys trying to be better than the other. if i find that thread again, i will let you know.

4-2-1 header, intake, suspension, upgraded tires; all those would cut down your times.

for auto-x and slaloom i cant emphasize suspension and good tires enough, good friend of mine raced his d15 on autoX and consistantly was one of the top cars at every event. a good driver makes all the difference.

whenever my buddies go up to willow springs, they mention most everyone there runs on falken azenis. Tires and wheels are a good place to start. then beef up the suspension, and then simple bolt-ons should do the trick. Good Luck to ya!

yea dude suspention there are so many diferent classses for auto x you dont need to hook the the engine crazy to do good - your only racing ur self no one else - so go with full suspention tie bars strut bars and also good tires and 15-16 inch rimz
good luck -

thx a lot guys but actually .. i wanted some ideas :P .. instead of suspension and tires/rims (already done). You know just to beef it up a little ... here are the thoughts i had .. let me know what you think

1- Si transmission
2- Accord injectors (worried about the ratio air/fuel tho)
3- Si intake (again ... maybe too much air?)
4- Si ECU or else since Si has VTEC and my motor dont

i/h/e are already done (4-1 header comin) so thats about it ... for now :P

Suggestions wellllll welcomed!! :P

uhh you can't just swap ecu's like that from a vtec to non-vtec

why does it sound odd that your already circuit racing and yet you have no clue practically about performance mods? why does that sound backwards?

[BullShifter]

Tires & suspension are key but the best mod IMO, RACING SCHOOL! Pro instruction

You could have the fastest car on track but if you can't drive right, it's worthless.

first ... sorry for disappointing you .... i dont know everything ... i wasnt sure about the ECU thing .. thats why i asked ... arent those forums here for that????

second ... i want to race to quench my thirst of speed in a way safe for everybody instead of all the morons racing in streets. and because i just love it ... am i supposed to be an expert mechanic before being able to race???

thx for telling me it cant happened anyway ... now ill love to have suggestions ..... mechanicals ones please .... i know about all the driving school and all ... ive done one too .... can you guys answer questions with direct answers?

thx for inputs from all tho.

get a 92-95 EX transmission.
4-1 header
air intake
If you can run open header at the track, then do so.
Adjustable cam gear. retard around 4 degrees and you should gain a couple ponies up top
Many companies make a cam for that style of head casting (pre 96 non-VTEC)
dont worry about the fuel injectors, most honda injectors are the same flow rate @ 240cc
