With that you basically have to chip the ecu so you can tune the car. Slapping all the stuff on there without tuning is kind of worthless

*hit caps lock button until light goes off*

how can i chip DA ecu and how much would it cost? so wat ya think my compression should b den?

9.2:1 is stock compression...

I got mine chipped for $60 bucks. But then you have to pay for the tune unless you do it all yoruself.

o ok den so i guess i'll let someone else chip it for me den. Thanks. wat bout the hondata s100? would dat b also good upgrade as well or na?

s100 is a lot better than a "chip".

A chip on the internet that you find that claims to give you "extra horsepower" is crap. It does no tuning to your car what so ever so how could you have more horsepower? The s100 is pricier but there are cheaper alternatives to that as well.

cooL cool i like dat better den i will buy the hondata s100. thankz! but one problem though dey don't make the s100 for my ecu!! Can i swap a 92-93 GS or LS ecu to my RS or no good? or wouldnt matter at all.

If your car is obd 1 then yes, you can used it, if not convert the car to obd 1 and use the jumper harness then you can use a obd 1 ecu.

That might not be worth the trouble of going through for what you want to do. Might just want to look at an Apexi afc II controller. You wouldn't have to find a specific hondata tuner to tune with that as well.

OOH Okay but i believe i have a obd0 if am not mistaking. but am curious wat type of ecu i have. i dont noe if i really have a obd0 cuz i check in many websites and they only tell me that the 90-91 ls/gs are OBD-0 What bout the RS model?

u prolly have a PR4 OBD-0 ecu. one of the best bets if u want to get it tuned would be to either convert the whole car to OBD-1 and decied which tuning option u want to go for... or just get the OBD-0 to OBD-1 jumper harness and find the tuning option thats best for u.

correct me if im wrong but there are just so many more tuning options for OBD-1 compared to OBD-0

cool thanks. ama do the obd-0 to obd-1 conversion instead then thanks a lot guys.

what do you mean convert "the whole car" over to OBD1? The only thing effected by OBD1 is the ECU, distributor and injectors...

my bad thats what i mean

There are a lot more tuning options for obd1 over obd0. It's whether he wants to go through with changing the ECU, dizzy, and injectors to get those options. With a pretty good build it is almost a must.

ok cool, i got another ques wat is the original size of my 90 integra throttle body? because i plan to buy one but wat am lookin at is the skunk2 60mm and 67mm throttle body.
