I just bought my first acura integra a few days ago. Its a 1990 ls. The motor was built 20k miles ago. It has crane #12 cams, wiseco pistons, and eagle rods. The car is kind of fast but I want to turbo it this winter. I have experience with turbos but not with hondas. My question is. If I ran 15psi of boost what will I need for fuel system and engine management setup? I planned to use a walboro 255, rrfpr, and a missing link. Thats the setup I usually run. Will the stock injectors handle it? Give me some input please. I dont want to use a wideband. I plan to tune the fuel with a pressure gauge. I also heard someone can map the ecu out? I dont want to spend a butt load. Thanks for the help!

 

keep adding your fuel components, stock injectors wont cut it, i would run 440+ injector size. youre going to need a management system such as hondata. i think tuning with a fuel pressure gauge would be a great way to go. your best bet is taking your car to a reputable tuner who will chip your ecu and adjust your map, running you in the price range of about 500 dollars give or take.

 

Let me make sure I go this straight before I spend money. My best bet would be to use the rrfpr and walboro, and get someone to tune my ecu for me? How do I find someone to tune it? If I use bigger injectors, wont it run rich at idle? Where do I find injectors? I thought hondata wont work with ob0? Like I said. I need to keep it cheap because it needs the body kit fixed and a new paint job while its in the garage.

 

You have a lot of research to do before you jump into a project like this.

First thing, is go by how much power you want not the amount of PSI. PSI doesn't mean very much.

yes you need to do more research and build your engine for your power goals... the reason psi doesnt mean much is because of the size of turbo you plan on running for example.. a small turbo at 15 psi may give you 300 whp while a larger turbo could give you 350 whp (not exact #'s, its just an example)

so decide what your going to use the car for (DD, autox, drag) and then decide what you want your power goals to be, then you can build for your exact turbo setup

 

Well to run 15psi on a stock block isn't a good idea...I would say 12psi max but thats up to you. As far as fuel/engine management, just chip the (im assuming its OBD0) computer and use turboedit to tune the ecu and add a boost map. then you won't need the missing link to trick the computer when you can program it to do the exact same thing. As far as fuel you could pick up a set of used 450cc dsm injectors those are capable of handling 12psi. I don't think you would need a resistor box but don't hold me to that. You also wouldn't need the rrfpr if you tuned it using the software, if you used the fpr then you would need a high pressure fuel pump. With honda's its so much easier just to chip the ecu and go from there, IMO its not worth using a rrfpr to get the job done when it comes to boosting but thats totally up to you...

Before you decide on a way to go there is tons of info on the net so take a week and a few hours to cram in ideas.

I am also about to turbo my integra but I have a 97 GSR so I had to buy a conversion harness to use and OBDI ecu. P06 I have chipped, added vtec and IAB support and added Hondalog to the case for datalogging. I will be runing about 8psi using a t04e turbo and all is going to be tuned by me using crome ,a wideband(this is recommended, but you can use the narrowband but you only will get a rich/stoich/lean reading not actual a/f) and the street...

BTW when turboing the word "CHEAP" should never be used. Finding deals on good parts is ok but never cheap...look to at least spend $1500 on parts for a decent turbo kit if you know where to look :D

I would ditch the bodykit if its one of those 200 dollar ebay kits, when I bought my car it had a kit on it but luckly the guy had the stock bumpers still so I sold the body kit an put the factory bumpers back on, now I don't have to worry about cracks everytime I hit a bump, whewww

Are people even reading my posts? THe motor is built. They built it to withstand 700hp. I think the tranny has a lsd by the way it drives. Anyways. Like I also said I am not new to turbos at all. I have built 4 turbo cars within the last year alone. I was running 13psi on a stock dodge neon. Running 12's... No one has done that ever. Back to the point. I know what I want for power. I know there are alot of things I can do to raise the power with and without the turbo. I dont care about that. I plan to use a small Mitsubishi to3? or is it te3? Anyways I want it to spool fast... The turbo is good up to, I want to say 18-20 psi? Which I dont plan to run. So from what I got from the posts, 450cc injectors, then a tuned ecu. True? Is turbo edit like megasquirt? BEcause ms is hard to setup :-(. The reason I am asking is because over the summer I helped turbo a 89 prelude si. We were having fuel issues under boost. We ditched the missing link, and rrfpr and paid $250 to someone on a forum to tune his ecu. Then the car ran great. I dont know what kind of a/r he has because no wideband. I just hate to blow it up over something stupid. I still want to run a shot of nos on it.

 

for building 4 turbo cars in the past year u dont sound to mechanically inclined about turbo setups ....u have alot of research to do on your own dont expect to get spoon fed all the info you'll need..one more thing...so your saying that no one has made a stock neon run 12's ...u honestly think yr the first one ever to do it???


enuf chit chat ....now seriously to help u out.......

first off what are your what are your whp goals

that is basically going to determine what turbo and injectors you'll be needing
450cc usually max out there duty cycle aroung 270 whp so if u plan on pushing more than that i would go bigger...


ok u said u wanna run a small mitsu turbo ... so im guessing u'll be running a t3 housing 14b or something like that.... u could go a lil bigger wit a t3/t4 hybrid and still get the fast spool with more top end power.... it all depends on what ur goals are u need to be a little more specific and a little less cocky so we can try and help you out....

for tuning i would suggest converting to obd1...just buy conversion harness and then u can run something easier to setup i.e hondata, crome, neptune, most tuners can burn you a base map and you can start from there ...then u can buy a datalogger and chip burner make adjustments yourself ...personally hondata s300 or neptune rtp are great options for a standalone ecu....u can make alll adjustments on the fly as long as you have a laptop...are u planning on tuning yourself or you going to take it somewhere ???

First one to run that much boost on a stock neon that runs 12's... I seen plenty of neons run 12's are you kidding me? Sorry for being cocky. But other forums give me straight answers. I dont need to milk people. I have the turbo kit ordered. I found someone locally that is going to tune my ecu for me. I will just use a wideband and go from there. Thanks for the help...
