How long can i drive without a tune for 18g?
Lets say I can't get a tune the day after installing the 18g, how long can I drive it without a tune and will it really suck to drive throughout that period?

Install it before you drive to the shop and drive COMPLETELY OFF BOOST the whole way. If the car even runs properly, there is still a big chance that something could go wrong. If you must drive it untuned, stay off boost at all costs. The best thing would be to have the car flat-bedded to the shop.

i also got the other mods too if it helps, sti pinks injectors, walbro fuel pump, uppipe/downpipe...
i wish the tuners themselves could install the turbo right there but theyre just tuners. |

what EM are you going to be using? If you are going with UTEC then I would see if you could get an 18g map for similar mods and run that on your way to the tuner. ECUTEK I might consider mailing off your ecu to get a map loaded and then drive your car to the tuner.
Also, the sti pinks are likely going to be maxed out so I would suggest looking at something that flows more, either modded stockers of UR or PE injectors. I would also highly recommend an intercooler upgrade for an 18g as well. Alot of people would consider a larger intercooler a must have item for an 18g. Good luck. |

wait is this fear based on the prospect of running lean? if it is i cud just get a manual boost controller for 50 bucks and turn down the boost...right?
I'm gona try to tilt my intercooler so that air hits it more forcefully through the scoop |

Volume and pressure are two different things. Even if you're running very low boost, you're still flowing substantially more air than the ECU will expect. If you must drive on it, do NOT go on boost at ALL. I cannot stress this enough. It is possible if you shift at 2500 RPM and don't go above a reasonable amount of throttle.

Like everyone said, don't drive it. The 18g is alot different than a VF series turbo. Turbo XS has "base maps" for their UTEC for the VF series turbos that make it somewhat driveable.
~First of all you will need bigger injectors ~Do you even have EM? ~You will need a bigger intercooler. "Tilting" your intercooler isn't going to do anything. You need either a bigger TMIC or a FMIC. The heat soak is going to be entirely too much for your stocker. ~Don't bother with a MBC. Make sure you have everything you need first before you just put on a new turbo, or you will F your car up. I really hope you know what you're doing, because it sounds like you're headed for trouble. Best of luck though |

you'll be fine driving it bro, just load up stage 4 map, hell I ran my sti with stage 2 utec map, and just tuned in the new 850 injectors and drove my rotated turbo set up 2 hrs to turboXS on that stock map which is for the vf39, I called them first and they said it would be fine. The main thing is you have to have your injectors tuned to be able to drive it, but if you are useing the utec and load the stage 4 map in and the parameters it counts for the new pink injectors and you'll be fine, but just dont go in boost much if at all.

Dude, you’re going from a 300cfm turbo (stock) to nearly 600cfm, obviously you’ll need an upgraded IC setup to efficiently cool the increased charge, otherwise it’s not even worth getting tuned with 200F+ intake temps
As others have stated, your injectors are too small for this turbo. I’m sure it can be turned with pinks, but you’ll be limiting your boost in the upper RPM because the IDC’s will be maxed out! |

do you have guages so you can monitor everything? just take it easy and watch your guages
hopefully it's not a long ride... on your way pick up a bigger i/c and injectors |

Silver -- why are you cutting corners? From your tranny forum posts you appear to be resisting the valvebody upgrade that the 18G should IMO have, and at the same time are thinking of using Pinks on it, and don't want to have it flat-bedded to the tuner?

re
I agree with what Jon said. It was spot on. Most curves I've seen don't deviate much at all until the turbos spoolup. And all of the curves are wide open throttle which I would not recommend for sure to get it to a tune. You basically want to follow the normally aspirated path of the curve and avoid massive deviation from that. Its hot out now and the air is thin so that helps you too. Also light partial throttle is lean but forgiving at city speeds. Its lean and very hot at highway speeds though. If you stay away from the heavy load columns by using 1/2 throttle or less you avoid spooling up much.

I ran my car with a vf22 on it for about 5 days w/o engine management it ran like **** big time but it ran and I didnt have any problems. then I got my utec, put it on downloaded the stage 4 map from turboxs for the vf30 set my injector size to 650cc and ran the car like that for a good period of time and I did run the car very very hard nothing happen thank god. I personally think u can do it. Just download the stage 4 map vf30/34 from turboxs set ur injector size and you go EASY (EASY being the key word in this statement) on the car meaning no wot pulls you will be ok for sure not forever but for a decent amount of time.

And with the larger injectors and stock fuel mapping, this is gonna idle how?
Cutting corners always will end up biting you in teh rear. Just flat-bed your car to the tuner. Just my opinion. |
