nope, in simiplest form. Essentially you will need to remove the MAF, add a MAP sesnor and have a stand alone management system as you will be removing such sensors at the FDIC (i believe thats the sensor)

i haven't done extensive knowledge on the GTIR, but i know its an OBDI car and i believe it has fewer sensors. check out www.sr20forum.com

One of the rules here is NO BUMPING of threads for 24 hours. We all have lives and you need to be patient.

Will not work on a stock ECU AFAIK as it has different sensors. than the USDM car.

Sorry, wont happen again.

What if I install the GTiR throttle and I install a MAF as in the DE intake??

would that work??

Thx

re read that, it doesn't make sense, but if you instal the GTIR ITBs you can run the DE IM as it replaces the IM with the ITBs. If you want to run the ITB's you will need a MAP sensor and a stand alone. And secondly, there really wont be a large gain unless you have a pretty modded car.

Maybe I havent expressed myself correctly but I'll post a picture to clarify my point.

just its more then just adding the MAF in place. I believe the FDIC and TPS are in different spots. Remember, that is a JDM obdI car, which is different then the USDM models

To add in my two cents...im sure you could make it work, granted you adapt the correct sensors, install a maf as stated, and use the proper size injectors. Pretty much you need to end up with all of the DE sensors, on the gtir intake. The only problem really comes down to the egr system, and how much work you are willing to do to make it work. AND... As long as you use the appropriate injector size, correct maf for the computer being used it won't matter...the maf doesn't know what engine it is connected to, it just mesures the amount of airflow. If all of these were problems, we couldn't use ANY non stock design of aftermarket intake on our cars, nor could we change the throttle body size, etc. I know other people have succesfully done the ITB gtir intake swap on to a de...unfortunately...I don't have any normal DE's laying around to compare for you...only gtir stuff ;-)

Thx for your comments

I wish I could say the same about having only GTiR stuff... hehehehehe.. maybe soon...but what is the EGR??

To control the bigger MAF and Injectors I just bought a SAFC-II that according to the comments on SR20forums it seems to work pretty good.

i think the biggest issue is Not the MAF but rather the FDIC and TPS issues as they would have to be relocated.

Finally I took the Stand Alone option, I will be using a Haltech E6X for my SR20DE motor, so bye bye MAF and welcome ITBs and Velocity Stacks.

i really hope you didn't just drop a grand just for the ITB's to work. you will have mininal gains unless you heavily modded, hell it would prolly be cheaper to buy the motor.
