read the engine management FAQ

Re: 90 si turboed
 

so are you running your car on the stock fuel system?!?! :S

Give us some pics. My bro (cobrarstreetracr) and I are doing a similar build on his 89 hb Si, but with a T25! :y

Re: 90 si turboed
 

complete stock injection even with 87 cuz i havnt gotten to the gas statation pic will come some time mid week

Re: 90 si turboed
 

how much boost are you running?!

Re: 90 si turboed
 

:-X

Re: 90 si turboed
 

exactly what i'm thinking, doesnt seem like the motors going to last very long like this!!!

Re: 90 si turboed
 

No fuel management...I would park it till you get the fuel side done.

Re: 90 si turboed
 

there is no sence in going to all this work only to skimp out on the most important part. I agree, park that puppy!

Re: 90 si turboed
 

like 5 or 6 pounds i dont take it past 5 and half cuz after that it leans out i need to find out how to run my dsm 450 they flood my engine when i try to use them

Re: 90 si turboed
 

lol they'll do that ----. sounds like somthing id do 8) i always get impaitent and jump the gun. chip your ecu

Re: 90 si turboed
 

Are you listening to the stuff that's being posted?

don't drive your car! 87 octane and a stock fuel system....KABOOM! You're an idiot!

You need some way to control the 450s....at least go buy a chipped OBD-0 ECU with a basemap

Re: 90 si turboed
 

Re: 90 si turboed
 

(shameless pug on) i have a chipped PMG for 80 bucks shipped(end shamelessplug)

Re: 90 si turboed
 

i got 275 cc injectors from some dude i know he aslo have 360 and iam gettin some 93 and seein how it runs

Re: 90 si turboed
 

you need a way to control the bigger injectors. It's going to run like ---- if it even runs at all ::)

Re: 90 si turboed
 

Pics of the blown engine I'm assuming

Re: 90 si turboed
 

what the hell dude

Re: 90 si turboed
 

im taking it that you dont really care or want to take any advice.

Re: 90 si turboed
 

this is not going to cut it, bigger injectors aren't going to fix the problem without someway to control them, i mean jesus even an fmu would be safer than what you're doing! Not a whole lot safer mind you... but sweet jesus man give your car a fighting chance.

Re: 90 si turboed
 

I guess if you dont make a post soon we'll know its because the car blew up

Re: 90 si turboed
 

I have school i have to go to and cant aways post. My friend told me to get a chiped p28? and the obdo to obd1 harness and he has the program to run the 450 at 9 pounds of boost.. iam not a big computer nut. I need help on learning how to tune and dont know ---- about tunin yet.that is why iam tryin to learn this ----. yes i know all about to lean that is why iam not beatin the ---- out of it or goin over 4and half grand i watch the a/f gauge

Re: 90 si turboed
 

You should even be driving it.

Re: 90 si turboed
 

my ride to school

Re: 90 si turboed
 

My advice to you is to carpool or hunt around for a new motor.

Re: 90 si turboed
 

the time bomb is ticking!! :o

Re: 90 si turboed
 

why dont u help me with tuneing my ---- tell me what i need and how to do it ? instead of taken guesses how long my motor is going to run? lol

Re: 90 si turboed
 

you dont' know ---- if you're reading that narrowband air fuel guage ::)

Re: 90 si turboed
 

Dude, buy some overnight parts from Japan. You're gonna blow yourself to pieces.

Re: 90 si turboed
 

For starters your going to need to chip your ECU, and use one of the mangement programs (depending on your OBD generation) and get someone to burn you a base map, then get on a dyno or find someone with a wideband to tune it. I would start reading about the programs and go from there.

Re: 90 si turboed
 

We already told you way in the beginning of this thread.

Go read the Engine Management FAQ's

Even 1psi is too much on your stock fuel system. It might be holding up now, but that doesn't mean it is fine. Everytime you drive your car boosting it you are killing your engine, plain and simple.

Of course the car is going to flood with no control and 450's in there, and it will also flood with anything over stock. The 450's is almost double your stock system, without any form of control the car won't run.

again Go read the Engine Management FAQ's or you really will be posting pics of your blown Si, and if it is your only car to school I would be worried, it doesn't sound like you have money to get a new engine.

PS Air/Fuel gauges are only a pretty light show, they don't work for ----, or let me rephrase that, they are not accurate enough to trust while driving a boosted car.

Re: 90 si turboed
 

everything above x2

Re: 90 si turboed
 

iam going to do the p28 obdo to obd1 conversion and chipin it as soon as i find a p28 an get the chip. some one i know had the same set up on his car and he still have the soft ware to run a 14b with 450 at 9 pounds

Re: 90 si turboed
 

No two cars are alike, even with the same parts. Engines all react different to different modifications, but it would be a nice start to better tuning later on.

But seriously, right now, if you keep boosting it, it won't last. open up the wastegate or take out the charge pipes or something. Or start saving up for a new engine.

Re: 90 si turboed
 

Get that wastegate open, and pop that charge piping off and just let it run naturally asperated with a filter until you're ready to tune, or theres always carpool

Re: 90 si turboed
 

Hey I just said that ;) :-* :y :y :y :y :y

Actually carpool sounds like fun :X :X

Re: 90 si turboed
 

well it was such a great idea i wanted to force it into this confused kids brain to make sure it gets done... well that... and i'm a loaner :y

Re: 90 si turboed
 

;D ;D ;D O0

no problem homie..... :6 :6 :6

Hopefully he will listen

Re: 90 si turboed
 

ok so i opened the wastgate.. lookin for a p28 and buyin the harness and chip

Re: 90 si turboed
 

did you disconnect the charge piping?
