hi there i have been looking into truboing my accord and have come across a dilema. i have found a turbo kit that comes with two extra injectors with an interface and controlling programme to add more fuel under boost. however i have been looking at possibly upgrading the injectors or leaving them standard dependant on what size they are and then running something liek hondata and having it tuned using the injectors already fitted. i dont know what the pros and cons are of each way of doing the fuelling so any advice would be great.

ps the turbo kit comes with everything but you can reuce the price by $400 if you dont have the fuel management so also cost effectiveness of each way of doing the fuelling im also only looking at running at most for now about 8psi which would put my car around the 230-250hp range many thanks -rob

 

alot depends on what year car you have, my friends 02 civic turbo kit came with the smae extra injector set up, it works pretty well out of the box, although it is some times a pain to figure out where you need to add more fuel etc.

 

its a 1999 model honda accord its a 2.0l vtec sohc which i know alot of american guys have not heard of but i would imagine all the principals are the same it has an obd2 ecu. why does the year of the car make a difference?

 

well being obd2 you cant legally convert to obd1 and use a p28 which is the best solution.

right now he is running the injector controller, vafc and a innovate motor sports LC-1 wideband

 

Where are you from and how strict are they on testing vehicles??

I would highly suggest getting conversion harness and a reprogrammable ecu (hondata, ectune, neptune, crome...) over a fuel controller with external injectors, especially if it won't cost much more (saving $400 on the kit).

If they do strict testing of the vehicle, keep all of the stock (ecu, injectors, etc) parts, and put them back on for the test, then just put everything back together and you are good for another 2 years or whatever.

 

im in the uk and we just have a standard emissions test which must fall within a certain limit for all the fumes etc not sure exact amounts but why can you legally convert from obd2 - obd1 is that an american thing? and our tests are done yearly

 

in the us, if you have an obd2 car, they just plug in the test machine to the obd2 port in the car and check it from there. if you convert to obd1 that port no longer works and you fail the test.

 

oh right odd i dont think they do that here the port is only ever used for diagnostics as far as im aware cos not everyone has the software for it all we get is a probe stuck in the exhaust which measures the ppm of different things liek co2 etc then therest is done as visual inspections so i dont think it will be an issue on the obd swapping the only down side is that not many people over here tune hondata etc so may end up having to buy the top of the range hondata that comes with the software and the usb plug in but thats about $500 plus a p28 ecu about $100 so looking at approx $200 more to use a full management system but then if its going to be better on reliability and performance might be worth it

 

It is definately worth $200 to have something way better. Otherwise check out ectune or neptune, just as good as hondata and cheaper.

About testing, Im in Ireland and we made 380 whp on an ITR that I tuned and passed the emissions test a month later, which is probably similar to yours, so it isn't too bad. You could get it tuned well and pass with your set up, or switch back to stock for the test. I am also going to try and pass a car with no cat and running E85 sometime to see if it is possible to pass without a cat.

Only certain states test in US, so if you are in those, you have to switch back to stock, but otherwise you can run obd1 in the other states no problem.

 

wether the emissions pass the test or not i think by law you must still have a cat fitted after a certain year so if they spot it not having one they can just fail it for that thanks for the input i will prob go the route i was looking at then with the p28 and hondata just trying to find somewhere uk based to get the parts together most of its in the usa which is a pain
