Hey all

I just picked up a 89 mirage turbo for as Christmas present from my wife. It has the stock bottom end block and pistons, but its has a small fmic, true evoIII 16g, 550 injectors, and a GM Maf. Currently is pushing about 18 psi and dropping down to 16 psi at 7k. Are these safe numbers, is there more head room in the turbo and injectors? My previous turbo car was an evo9, so it was flashed for the mods it had and put down 363 on the stock turbo, and pump gas, it was definitely a Wednesday motor as they say.

So what is the best way to tune for this setup,? is there more power to be made with the current parts. What plugs and motor oil do you guys recommend as I going to do those this week end.
Thanks

see that maf translater box up by the strut.. inside there is how u tune that type of maf..(there are instructions online if u google it to help with how to tune it).. theres not alot u can do with it tho.. I would say 17 psi is about max for those injectors even tho im sure others have ran higher..im at 17 psi myself but im on 660s and im running sped density with jackal for tuning.

the turbo can easily run 24-27 psi.. but those injectors wont.

I dont run anything but NGK bpr7es plugs.. as for oil its your preference.. everyone is diff.. I run castrol gtx.. used to run royal purple till it went up in price... alot use mobil 1... stay away from fram oil filters tho ( if u search about it u will find tons of posts on how there bad for our motors. mostly cause they dont trap as much dirt as other filters do.) I use the bosch 3320 filter when they have them in stock..but again its users preference..

I would run oil with lots of zinc in it, even though that's a lot more important if you have a ball-bearing turbo. Valvoline VR-1 is good, or Delo Grade diesel oil like 15w-40.

The EVO III 16g has a lot of potential. People regularly make 400whp with it in AWD cars. If you run race gas or E85 and crank up the boost it will haul ass, but you'll need to upgrade your injectors first. It all really depends on how much power you actually want, and what kind of fuel you want to use.

I concur with what was posted above. I ran 23lbs with good AFR's with a 2gMAF, e316g, 560's, Wally 255 ad an AFPR on my Talon before it went to my son. I know the injector Duty cycles were higher than the 85% recommendation, but I never had any issues. I also recommend the Delo diesel oils. I run Shell Rotella 15w-40.

I highly recommend getting ECMlink v3 with the GM cable. You will then be able to get rid of that MAFT box. It will be much easier to dial in those bigger injectors you need to run more boost. I too second high zinc oils but they can run havoc on emissions and Cats, I personally run Brad Penn 20-50. I also agree with NGK bpr7es.

If jumping ship to ECMLink don't bother buying the native GM MAF cord. Go straight to a Speed Density setup and call it a day.

If we're suggesting things, I say socket that stock EPROM ecu and go Swede Density, lol.

Seriously though, I wouldn't do any of the above mods without a wideband in the car. Not sure if there is one already. If not, do that first .

I just assumed he wanted to stay with the GM Maf it's kind of welded in Although you can run them both until you get SD all dialed in if you wish.

Thanks for all the great replies guys. I prefer Royal Purple as that is what I ran in my Evo along with Bosch or Mobil 1 oil filters. The nkg7 or those stock heat range or one step colder? just would like to know to have a reference.

Ok, so down to the meat and potatoes. Ideally I would want a set up that I could take to English Racing and they could really dial it in, in regards to fuel timing, and map via a laptop and the dyno. Step one sounds like I need to install a wide band guage. Step two sounds like more fuel 650, 700 what would be appropriate in regards to maxing out the turbo's efficiency and not over working the injectors. Step three would be the chip, flash, speed density etc. I would a reliable total system to tune it

Thanks

7es are 1 step colder. If you want to stay with that turbo and just run a chipped ECU I would say somewhere around 800s would suffice. If you're going ECMlink just go big or whatever you can afford 1450s ect. Link is going to give you a ton more options and more freedom than any other chip could offer. It will also be easier to tune and probably cheaper if you ever decide to get retuned from English.

If your ECU is already socketed it will be that much easier to go Link (reliable and total).

I agree u can always go bigger injectors and detune .. I would go to..or call english racing (if they will be the ones tuning your car) and ask them if they know how to tune with ecm link..also if they know how to tune with jackal..(and ask which they prefer to tune with if they use both) this will give u options for tuning software.. personally I dont like link.(dont like the setup..over priced IMO and unless they updated it in the past few years link was only a speed density simulator..not true SD).. but thats just my opinion.. I will stay with jackal/werewolf untill I get aem.

If you want to make real power on E85, you need at least 1,000cc injectors for a proper 16g setup. If you want to use race gas, you could get away with something in the 700-800cc range. A set of cams would go a long way too, if the engine doesn't already have upgraded cams. Stock 1g manual 4g63 cams are a common upgrade, but if you want to max the turbo out you will need something bigger than that. I'm a big fan of the FP2 cams, which are made by Comp. Not sure if you can get them anymore from FP, but from Comp they are the 101200 grind I believe. That's what I run in my car. They idle like stock, and give plenty of top-end and mid-range power.

Royal purple or any synthetic oil for that matter really isn't necessary, but if you want to spend the money on it, then by all means, it won't hurt anything. I'm a fan of running standard oil and changing it often. I often do oil changes every couple-hundred miles, but I also don't drive my DSM very much.

E85 is not on the radar, there are only a few gas stations around here who sell it and imho it's a pain in the ass. I will stick with 92 pump and 101 trick fuel if I run two different maps. So the current ecu in my car, is it specific to the turbo mirage? Can I swap in a 1g dsm ecu like plug and play? Yes English does alot of 1g dsm, they have one that runs low 8's so ecmlink shouldn't be a problem.

I will Google the jackal setup, and check it out. So a cheap setup would be a flashed chip and some 800 injectors, hi impedance bosch style? The motor has the "C" grind cam on the exhaust side from a 92 and adjustable cam gears. I would be worried bigger cams will push the power band up that much further. It really doesn't any boost until 3500 and then it redlines at 7000

Thanks

Eff jackal/WW...www.dsmecu.com has a new contender with way better options, TRUE SD ( all maf code removed from the hex), anti-lag, rotational idle, TRUE spark cut anti-lag, and hybrid alpha-n/MAP mapping, and is free!

and costs double the price to get everything.. I had link back in 05.. hated it...used it 2 years ago on a friends car and still hated it...but like I said its just my opinion..
