ok I just got a turbo kit. Im just getting into the hole turboed SR20 thing. I have stock bluebird kit. T25, 370injectors.top mount. everything I need to bolt it on. expect the ECU. What are my ECU options.

One more question. If I install this kit on my stock 92 SR20 ecu and run on the stock 7psi wastegate will I be ok until I get a ECU.I know it will run rich but I will not hurt nothin right? will I still be able to boost on the car. I will not run it like this for more that a couple of weeks. also is there anywhere that sells 10psi wastegates.

Last question. My SR20 has 90k on it. you think it will have alot more life left in it running around at 10psi on a daliy basses. I will not be running anymore than that. I just want a nice little street car.

ecu
jwt 9:5:1 with 370's an t/25

or s-afc,EGT


10 PSI TUNED CORRECTLY will last quite some time..
no oil leaks,runinng the right amount of timing,an fuel an your str8

an yes u can run at 7 psi on stock ecu its not suggested by many but as long as the boost is only 7 then your ok.. for now

You will run pretty damn rich. I had no SAFC, AND a leaky injector and I could still drive mine and it is an avenir so I"m running ~9psi. But mind you I only drove my car a total of maybe an hour like this. So don't do it for long. Get an SAFC and you will be fine, retard you timing to 15 base timing and you shouldn't have anything to really worry about at low boost levels.

is the JWT the only option I have for a ECU. I know will run rich as long as it will not hurt anything for a couple of weeks of regular driving. Also is there anyone that makes a 10 PSI wastegate. Im not going to run a safc. I want a ecu. Thanks for all your help. I know I will have more questions. Seeing that this will be my first turbo car. I know alot about turbos just not alot about the SR20 set up.

Running Rich Isnt The Problem Leaning It Out Is..
Danny...he will run rich. He would be running a stock ECU which is programmed for 259cc injectors and have 370cc injectors in there. He'd probably running so rich that black smoke will be very visable at idle.

isnt the u13 ecu programed for a lower compression? will that made a difference?

JWT isn't the only option, but it is the best, most reliable, and most proven option for a newbie. Why are you trying to avoid the JWT ECU? Expense? Time? If you go with other options, there's a good chance you'll end up spending more time AND money getting it set up correctly. If you have friends who are experts and want to help, the U13/SAFC may be a great option, but otherwise my advice would be JWT.

You asked about wastegates. People don't normally change the wastegate to run more boost. They usually buy a boost controller which intercepts the 'signal' to the wastegate. Manual boost controllers range from a few bucks up to about $100. Electronic ones are much more expensive. Do some forum searches on the subject.

As for running your car with the parts installed and no ECU upgrage, I don't know of anyone who has done that. It might not blow things up, but I'm not sure it will be driveable. You may dump enough fuel to ruin your catalytic converter as well. The better option is to install the injectors and ECU at the same time and drive the car for a while. Make sure there are no kinks. Then install the turbo. The JWT program for a turbo car alters things like timing (to prevent detonation under boost) but the main difference is the increased injector flow. There is no "turbo" switch that JWT flips on an ecu, so as a result, you can run their ECU with the 9.5:1 compression, 370cc program both before and after your actual turbo is installed. Note that if you want to change your MAF, this needs to be programmed into the ECU as well, and you'd also upgrade the MAF on your car before installing the turbo.

My advice is to do some more searches. It sounds like you may not be ready yet. Just some friendly advice.

LOL well thanks for all the advice SE-R DAN. You answered all my questions. but to clear some things up. I was planning to go with the JWT ECU. I just wanted to know if there was anything else out there besides the SAFC. I don't want to run SAFC. so JWT it is.

Second thing. I know that if I run the turbo without the ECU that car car will run rich. Im not going to install the turbo until I have the ECU.

Now the only thing here that I did not know was that I needed to change out the stock MAF. I though I could run the stock one and I would be ok. I will not be running more than 12psi at max. If I need to change out the MAF then what one do I need to get.

Also I know that you can get boost controllers to up and lower the boost. I was just wonder if anyone makes or has changed out the waste gate to up boost. I have searched alot about the turbo set up on these motors. This was still some small things that I was not clear on.

Thanks for the help. I think I have everything I need now

I would really look into e-manage, I know it isn't the recomended route for newbies but, if you can get someone with with the same tune it can be pretty simple. It's not like there are no other 9.5:1, T25, 370's, stock Maf out there. It's a pretty common setup. I just really like the emanage but then again I like to be able to mess with everything in my cars. :biggthump

I suggest go with emanage..jwt is a plug and play but if you plan on upgrading it later on, emanage will give you more room. As for safc, its hard as hell to tune it. But better than running with nothing at all!

zipstrips:

as for tunning your safc with your seutp, its different for every car. I try using other peoples fuel setup but it didnt run right on my car! So you will have to just floor it and add fuel to where it is lean...if you are cheap like me, just get a apexi TT 90.00 and monitor your o2 voltage for tunning...where every the voltage is less than .90 just add more fuel to it!!

That would be good info to know..im going to run the exact same set-up. I thought the safc settings vary from motor to motor correct me if im wrong.

thanks for all the info guys. with me im not going to be upgradeing. All im going to be running is a T28, 370cc, stock MAF, and the JWT ECU. I do not want to tune it. I will not be making this a race car. i just want a nice turbo daily driver. i think the JWT ECU will do just fine for my set up.
