Anyone know about tuning the obdll? Writing the new chips to remove the gay emissions programs stuff?
if you're serious about eventually going turbo, and you don't live in F'd up California and the smog laws, then I'd say go standalone with a base map and retune as required

I would also like to make a note on the MAF's. Don't bother changing out your maf unless you plan on doing some serious boosting over 15PSI. A stock KA24de MAF can read enough air (CFM) for the engine to make upto 250 CHP.
Most people that change out there MAF, only change out for larger diameters, and that isn't even that necesarry, sometimes enlarging the diameter of the MAF can decrease swirl, which would decrease the velocity of air traveling into the engine, as well as poor atomization.
As far as the 370cc injection is concerned you need to be boosted at about 8PSI on forced induction, or if running N/A you would need a Compression ratio higher than 11.1:1, and you would also need to advance the cams and ignition timing, which I plan on doing as soon as I get the rest of the cash I need to finish this damn project. A 250CHP boosted KA will cost the same as a 250CHP N/A KA. Like Raine said you are just rearranging the internals to perform differently, and the fact is neither N/A or boosted will be smogable at those levels of HP anyways, so be prepaired to pay major scratch, I happen to be lucky and know a few people at the DMV, I also realized that up in Northern Cali they still do idle smog checks and no visual inspections, so I may be registering my car up in CHICO. That level of power will pass on idle smog check, not dyno smogs that run the engine upto 3000RPM. The reason is is that as the engine injects more fuel and air, it will also increase NOX, and Hydro Carbon levels (basically cylinder temps go through the roof as you accelerate the engine).
All in all what I try to express to people tuning is that weither you go bosted or N/A for streetable HP numbers the cost will be relative to what ever your build.

so, if you take your car to get dyno tuned, then you don't need to own any type of management system? Do you have to buy a new Ecu.
Say i was doing I/H/E, larger TB, and a new cam.
It would be worth it to tune right?
What is needed to get your vehicle tuned under those specs. Or is it a drive-in .. tune .. drive-out type of deal?

alright thanks guys... So i'll just put all the parts on at one then, no point in wasting my time/ money. PLus, the turbo setup would be bigger than 370 injectors... With the ECU tuning/ fuel mapping, i have a friend who can do it for free. He's got lots and lots of experience with it too

don't flame me for this, but how fast will a 250 CHP N/A Ka24de powered 240 run the quarter mile and 0-60? I know there are other factors involved, but ballpark...?

Depends on the driver. I saw one N/A KA s13 240 get a 13.3 seconds in the 1/4mile. It was faster than a 350z due to it's lighter chassis.
My boy Monk is runnin between a 13.8 and 14.0 with his 350z and the chassis is a little more than 1000lb.s heavier, and it's the touring edition.
A s14 with that kind of power can probably run mid to high 13's.
Just adding a 50shot of NOS could probably put you in the 12 second range and a little more than 300CHP.
Don't know 0-60's but if you want something relatively close to the 0-60, look at the times for the sr black top s15, or s13 swaps, the transmissions and body weight are the same. The time will probably be a few points lower with KA since you shift earlier in the rpm's.

that may be, but I can't think of a better way to get an idea of how fast a car is with a given setup... we don't exactly all drive in the same circles/tracks/roads and we DEFINITELY don't all have the same driving skills...

that should be like mandatory reading for all the dori-dori-bandwagoners we've had come along lately ROFL

"I got a Hachi and a 180sx yo... I'm ****in' Takumi and Impact Blue rolled into one driver yo... I'mma go SR + S15 conversion + 20/30kg coilovers because I'm master of not spilling my water in my paper cup that my dad puts in my cupholder-less s13 yo"

Since, Vin and Raine seems to be the headliners for this topic... my question is... which engine management system/units/piggybacks have you used, or are curretly using? (It would be cool if you got some links, and maybe a tag price heh).

I've done some standalone ecu tuning on honda/acuras... for about 1k, you can pull a couple extra ponies outta an engine (hondata still sucks)

*first time seeing a standalone... my bud plugs his car's usb cord into his comp...
ME: sooo... does it come with a PS2 controller too?*

I gots a lappy, so that on the fly adjustment junk would be kick ***.

google "AEM EMS" and "Apex-i Power FC" and "Greddy Emanage" for starters. You should be able to find info, links, and MSRP's.

Don't try to get us to do everything for you.
