shaneomac1602 Posted April 26, 2009 Share Posted April 26, 2009 I bought my 05 LGT about 2 months ago, and I'm trying to decide what's best to do next. when I bought it, it came with: Magnaflow CBE, Perrin 1 piece dp, K&N drop in filter, white HIDs in the headlights and yellow HIDs in the ground lights. once I bought it I installed an Apexi turbo timer. I'm thinking about installing an SPT intake with heatshield, getting it retuned for it at the dealer, then an HKS SSQ. but after that I'm not sure. not looking for a lot of power, but a low 13 second car would be perfect. what would you suggest?

NSFW Posted April 26, 2009 Share Posted April 26, 2009 what would you suggest? Double-check the up-pipe. If it's stock, replace with a catless one, get retuned. It's just as worthwhile as the downpipe.

shaneomac1602 Posted April 26, 2009 Author Share Posted April 26, 2009 I don't have an up pipe. it goes: turbo-perrin 1 piece downpipe-magnaflow exhaust. I have everything on my car needed to a stage 2, but how do I know if it is tuned for it? Link to comment Share on other sites More sharing options...
shaneomac1602 Posted April 26, 2009 Author Share Posted April 26, 2009 also, I have built several turbo cars, and I know the first things you want to do is let the turbo breathe. so you need to replace the intake and exhaust. Both for more power, and to put less strain in the turbo. why is that different on the LGT?I have 2 buddies that have 06 and 07 WRX's and they both have SPT intakes and had the ecu retuned for them at the dealer. both have about 15k-20k miles on them, and neither have had any ill effects. thus the reason I want an spt intake.

NSFW Posted April 26, 2009 Share Posted April 26, 2009 Your car has an up-pipe, I assure you. It's upstream of the turbo, it connects the exhaust manifold to the turbocharger's exhaust inlet. The only question is, do you have a stock up-pipe or aftermarket? The stock Legacy intake is pretty good. Far as I know, nobody with just exhaust mods has gotten measurable gains after upgrading it. The WRX SPT intake might be a fine piece, but dig into follow the link I sent above before you buy a Legacy SPT intake. Also, I forgot to mention an intercooler upgrade. The stock IC has failed at the boost levels that are well within the normal range for a BL/BP Legacy with upgraded up-pipe and down-pipe. If you search this site for "blown intercooler end tank" (or variations on that theme) you'll find more information. AVO and Perrin make good ICs, and there's a thread somewhere around here that has pictures of a homebrew IC that looks to me like it's going to work out very well. Find it and keep an eye on it.

AWDxBOOST Posted April 26, 2009 Share Posted April 26, 2009 dont get an spt intake, with a downpipe, uppipe and stage 2 i hit a 13.2 @104 so if ur looking for low 13s, you prolly are close Link to comment Share on other sites More sharing options...
shaneomac1602 Posted April 26, 2009 Author Share Posted April 26, 2009 hmmm, I've never worked with an exhaust manifold that didn't connect straight to the turbo, so now I understand what you mean by up pipe. ill take a look at it when I get home. I think for now I'm just going to remove the silencer on the intake and plug the hole for it. well i just spent the last 3 hours researching the Cobb Accessport. im new to LGT's, so i had to do some homework on it. i just have to say it is just an absolutely amazing tool to have, and i am definitally going to be picking up a version 2.0 in the next couple months. got a few things to tae care of first.

NSFW Posted April 26, 2009 Share Posted April 26, 2009 Consider the alternative before you buy an AccessPort: hardware: http://www.tactrix.com software: http://www.romraider.com & http://www.openecu.org/index.php?title=EcuFlash There are (probably several) threads about the pros and cons of each, it's worth searching for details.

shaneomac1602 Posted April 28, 2009 Author Share Posted April 28, 2009 well I had some free time this morning and checked under the car. I have a stainless up pipe on it, and the silencer on my intake is already removed. it looks like on my up pipe there are two bungs. the lower one has a plug in it, and the upper one has a sensor in it, but the wire coming from it is cut off about 6 inches off of it. my lgt runs fine, no lights on. any ideas to what this sensor is? and why is the other one plugged?

AWDxBOOST Posted April 28, 2009 Share Posted April 28, 2009 in case you wanted to put an aftermarket sensor in there? but i dont know why you would put one there, egt's usually go on the hottest runner, 2-3 inches from the head. so the #3 for us, or closest to the turbo Link to comment Share on other sites More sharing options...

foolds Posted April 28, 2009 Share Posted April 28, 2009 This car may already have a stage 2 tune installed if you are not getting Warning Lights. Link to comment Share on other sites More sharing options...
shaneomac1602 Posted April 28, 2009 Author Share Posted April 28, 2009 my roomate has an 07 wrx tr with an spt intake, and spt cbe tuned at the dealer, and he said my lgt is definitally faster than his. he said it pulls harder. I only drove his a few times, a while back so I can't remember off hand how hard his pulls Link to comment Share on other sites More sharing options...
NSFW Posted April 29, 2009 Share Posted April 29, 2009 An OpenPort or AccessPort, plus a laptop, would let you find out how much boost you're running. From there we could probably guessimate what sort of tune is on your car. Sounds to me like you have an UP and a DP and a corresponding "stage 2" tune though. The stock UP has an EGT sensor in it. I'm guessing that's what you're seeing. It's not unusual to disconnect that and use a resistor, but usually that also includes taking out the EGT sensor. I dunno why an UP would have two bungs in it. An OP or AP would also show whether your EGT sensor is still connected - if the EGT never changes, there's a resistor wired in where the sensor used to be.

shaneomac1602 Posted April 29, 2009 Author Share Posted April 29, 2009 I'm going to be picking up a laptop for a datalogger very soon, and ill post up what it says. also, I am planning on picking up an accessport in the next couple months. hopefully then we can see what is actually going on inside. I am very eager to see what is all done to this. I know it used to have gauges in it, and it belonged to a "James P. Larsen" who lived somewhere near Lake Park IL.

shaneomac1602 Posted April 29, 2009 Author Share Posted April 29, 2009 what cables will I need to datalog from the tractrix site? just the openport 2.0? or is that the wrong thing? I need to order cables, and get my hands on a laptop Link to comment Share on other sites More sharing options...
NSFW Posted April 29, 2009 Share Posted April 29, 2009 OpenPort 2.0 will work just fine. Use RomRaider for logging. Link to comment Share on other sites More sharing options...
