Title: 2009 Impreza 2.5 Turbo? Post by corywannamaker on 07/03/9 at 17:01:47 I have a 2009 impreza 2.5. After buying it I have been kicking myself for not buying the wrx. I was thinking about putting on a turbo kit. I am worried about the engine not being able to take much boost and blowing it up. What does everyone think. Or should I just suck it up and wait until I can get a wrx or sti. ;D 8-) |

Title: Re: 2009 Impreza 2.5 Turbo? Post by rallyrick on 07/04/9 at 08:17:08 Not sure about the engine's capability for turbo use, but I would be concerned about factory warranty issues. If you go ahead & bolt one on, then have trans or final drive problems, will the dealer honour the balance of remaining warranty or is the car over the warranty mileage already? |

Title: Re: 2009 Impreza 2.5 Turbo? Post by RyanHuber on 07/04/9 at 10:00:10 The reality is, stock NA subie motors don't tend to take well to turbocharging, unless you're running very low boost numbers. It takes quite a bit of money to get decent number increases out of a NA motor. All that said, I suggest you learn to maximize what you have, get your driving to the point where the power is the limiting factor, and then consider either a new vehicle or a motor swap. If you haven't already been, there's lots of info on turboing on places like NASIOC and Toronto Subaru Club. |

Title: Re: 2009 Impreza 2.5 Turbo? Post by corywannamaker on 07/04/9 at 15:01:54 I am almost past my power train warrenty. Traveling sales(what do you do) I read somewhere that the motors will take 6psi and I don't think that the money and work will be worth 6psi. |

Title: Re: 2009 Impreza 2.5 Turbo? Post by RyanHuber on 07/04/9 at 16:25:03 Yeah, it's an awful lot of money and effort to get 6psi, which is maybe ~50hp or so, ie not even really WRX levels. Once your drivetrain warranty is up, maybe you should consider a straight STI motor swap. I don't know numbers for what that kind of thing costs these days, but you could get in touch with some of the shops like Planet Motorsport or Fourstar and see what they're asking. It's still going to be a pretty decent chunk of change though. Another thing to consider, I did a swap on my 2.5RS and the hit in gas mileage was pretty severe. If you're going to be doing lots of driving, you might want to consider a second vehicle that's cheap to run and then keep the subie as a toy, or even the other way around. There's a reason I daily drive a Hyundai Accent now... |

Title: Re: 2009 Impreza 2.5 Turbo? Post by corywannamaker on 07/04/9 at 17:14:55 yeah after talking to some people I think that I will wait untill I have some miles on my car and then do a straight sti swap and go from there. I think that that way I can lesson some of the cost by getting ride of my motor etc.... Thanks for all you help |

Title: Re: 2009 Impreza 2.5 Turbo? Post by Jeannie on 07/13/9 at 11:47:09 Then you will want to get bigger brakes, which means you'll need bigger tires too. Maybe not necessary for rallying, but it sure will be if you want to take it on the track. Jeannie |

Title: Re: 2009 Impreza 2.5 Turbo? Post by jgardhouse on 07/13/9 at 13:31:46 Every so often, I see someone with a hot scoobie who says they wish they could go rally, but can't because they don't have the money. For the price of a tidy STI swap and some shiny bits, you can have a stage-ready Production Sport setup. I know which I'd prefer (But I hate Subaru's, so I'm biased :P) Heck, even if you just wanted to rallycross or the like (and have a beater with a skidplate and some HotBits on it), you'd at least be able to drive it to work after you hit some big ass rock at Sunday RallyX. |

Title: Re: 2009 Impreza 2.5 Turbo? Post by Nikola on 07/17/9 at 10:04:10 I was in a similar situation when I got my 2004 Naturaly Aspirated Subaru a few years back; as soon as I bought it, I started learning more about subaru, rallying, performance driving, etc and got really interested. It's possibly a sign of my newbiedom at the time that I really wanted more power (insert "tim the tool man taylor" references here;), but I ended up with a similar dillema to yours. My own opinion after research was that trying to pimp up the power on the NA car wasn't really worth it; I'd spend half the price differential of a WRX, to get a warranty-destroying, questionable-reliability, lower performance hack, while still keeping the brakes, suspension, and all the other RS/TS bits. At that point I decided to switch to a WRX; 6 months into my financing, it wasn't the smartest financial decision that I've ever done;), but it made me a much happier person than spending thousands of dollars on some bolt-on kits would've. Few years later yet, and potentially a bit wiser though still dumb as a brick I'll admit, I'm not even sure I needed that much power. I'm not regretting the switch, but knowing what I know now, I might not have. I know for a fact I cannot myself utilize the full power of WRX properly (let alone the Stage 2 kit that I installed), and I'm honestly doubting I'd be able to push the NA car to the limit the way I know some really good drivers would as well. If I had to do it all again, with the benefits of hindsight, I'd put money into suspension, brakes, durability & protection, classes, practice, and improving my own skills. At this point I'm not sure I'd even go for an STi swap, unless I got the differentials, transmission, suspension, etc in as well... at which point of course, matters become rather moot as to why not just get an STI :) Just my 0.02 cents:) |

I totally agree, Nik! Handling adds a lot of value, and driver education always pays off. I think a lot of people start off thinking "more power" when, really, that's the last piece you want to add. See you at GCFR? Jeannie |

Title: Re: 2009 Impreza 2.5 Turbo? Post by corywannamaker on 07/17/9 at 13:10:51 had some computer issues. Just had a little boy so don't have much time either. i will be at the rallyx in Bancroft on the 26th. I do have a 1997 legacy that I rallyx so that my 09 is only for the road. I am fully aware of the benifits of brakes and suspension(handling upgrades). I am getting Hot bits suspension and have yet to find a big brake kit( aside from the sti brakes$$$$$$) After doing some thinking I don't think that I would fully benifit from sti power. however 170hp just is not enough. I am putting on exhuast and intake, and I found some ohter things that will help. I would like to set the car up to do some track days and solos but it is my daily driver. So I am going to do all the handling things and some hp stuff. I have alot of fun in my rallyx car and it takes money too. Thanks all for you help and input. 8-) ;D |

Title: Re: 2009 Impreza 2.5 Turbo? Post by dtompsett on 07/17/9 at 13:22:38 170hp isn't enough? My Audi has 130hp... in 1988. My scirocco rally car is probably 90hp. I'm pretty fast in the old Audi... and i know plenty of guys who are fast in NA subies... it's not all about power. |

Title: Re: 2009 Impreza 2.5 Turbo? Post by corywannamaker on 07/17/9 at 13:27:50 I am aware that it can be fast and 170hp is not bad but I am used to and have driven for some time now cars with more hp and better handling ( after alot of work of course). I have been doing tsd and solos and track days for a few years now and I feel that with my set up handling and hp that I cannot go much faster or push any harder. |

It is Peter K. / Jimmy Brandt at Tall Pines last year. He was spanking AWD cars and I think that car has about 100 Hp. Drive it like you stole it! |

Title: Re: 2009 Impreza 2.5 Turbo? Post by corywannamaker on 07/24/9 at 07:11:35 Sorry I will not be adding the tubo to the legacy. that took me a secons to fiquire out. This is for my "street" car ;D |

Title: Re: 2009 Impreza 2.5 Turbo? Post by corywannamaker on 07/24/9 at 07:32:43 I think that this is have the issue, everyone seems to think that this is going on a rallyx car. It is not and if take a car with 90hp or 130hp and put it on the street/ hwy/ track days / solo most people would find that they would want more power. I could not agree more that power is not everything. However 170 hp on mosport and the ocassional trip to shanonville to run what you brung night etc.. has me wantinjg more power. I guess me and a few people just have to agree to disagree. |

Title: Re: 2009 Impreza 2.5 Turbo? Post by Dave Cotie on 07/24/9 at 09:50:26 Cory, I am not sure you explained what you were up to well enough. I think that a number of us would understand quite well that for track days on tarmac, 170 Hp is pokey. However I think there is a number of important factors here: 1. Being a 2009, I assume your car is still under warranty. 2. As Ryan pointed out Subie N/A engines are not well regarded for taking boost. 3. This is your DD. Don't screw around with your DD unless you like taking the bus. IMHO, I think if you have decided that you want a turbo, then sell or trade the 2.5i and buy a WRX or a WRX 265. In the end you will be much better off to spend the money you would on a turbo kit and installation on a new car, than some frankenstein turbo'd 2.5i. |

Title: Re: 2009 Impreza 2.5 Turbo? Post by Daniel_Buehler on 07/24/9 at 10:36:38 Cory, it seems you have the power bug, what will you do when you get bored of 5psi on the OEM block? If you want to go as far as changing everything around the block, you might as well change the block as well. ~~~~~ 135hp was fine for me at MIR. Anyone can go fast on the back straight. You don't need more than 135hp to slide from the apex of T2 to the inside entrance of T3... :D The big nut (behind the wheel) always needs more torque... ~~~~~ Norm, I want to see you in a car that's not your daily driver! |

Title: Re: 2009 Impreza 2.5 Turbo? Post by Donnie on 07/24/9 at 10:44:01 Cory their seems to be a lot of controversy about what works and what does not,on Saturday i'll give you a number for a fella that can sort "ALL" of this out "with" you ,the thing that i find assuring is that Rod "insists" on your input through the "whole" process. He makes all his own "cold piping"intakes"headers(by the way he refuses to use cheap ass mild steel that you get in that "BIG BOX" ****,"stainless only") he is a excellent welder never seen better. He also has a creative working knowledge with regard to turbos/he also has access to some of the "BEST" in automotive computers and/piggy back/standalone. He is very down to earth and first and foremost he is "reasonable" dollar wise.As an example of his knowledge."WE" created a system for my drag/street car that makes 725 hp on 20 psi/ and its stand alone,5ys ago and it still reliable/and quite streetable. I understand you're not looking for those numbers,but you want something that's going to do the job consistently,with out constant headaches and busted knuckles :) If interested i'll give you his number on Sunday he lives in Newtonville Ont 20 mins outside Oshawa. Talk to you Soon . Take care Don Morton |

Title: Re: 2009 Impreza 2.5 Turbo? Post by corywannamaker on 07/24/9 at 11:09:28 I do agree that a turbo is not the best sulution to my hp problem. I am sorry if I did not explain it weel enough. I think that I will just have to do the suspension and wheels tires etc.. ( handling stuff). I do have the hp bug but I will wait untill I can get a wrx or sti. I have tried to talk myself out of the hp bug but I just can't. Thanks for all of your post and input I do listen to them. See you on sunday. |
