Don't worry, you are not the only one. I think I'll finally get rid of the cloaking device... I haven't been spotted in 5 years but I see a ton of other cars. (Not forum members apparently)

I was going to do it this weekend when installing my Brembo's but the rear stainless brake line install ate up all of my time. What a PITA!

I nominate you for the "post cliff notes" job.

Uh oh. Look what we started. To each his own. Everyone has made some great points and is right or wrong in varying degrees. Either way it's the original point of the thread talking about how a BP TMIC is one of the best for STG2. Not the best or that the Perrin is the worst. I made my opinion clear that the perrin design sucks. I said it, it's my opinion. Put it in another thread please? I'll even start a "Perrin design TMIC RANT thread" if it helps?

I hear ya FB. My only point is that the design is improper and the possibility for detonation is greater on a piping hot TMIC with a runner that is too large and too short for the air to cool effectively. Please remember that the point of this thread is that a BP modded TMIC is ONE of the best, not the best for STG 2 power levels. If you want to refute that the design of the perrin design does not suck, that's fine and I can relate to that. Lets start another thread if it hasn't been bashed to death somewhere else already.

The design sucks. They do the job but the heatsoak is a big issue for me. They will make more power because of the larger runners but the runners are too short to cool efficiently in relation to the runner diameter. (And that has a huge impact on cooling efficiency) The runner length is no different then the stock one but the runner volume is much greater. (if you increase one you must increase the other) The Process West WRX (Legacy fitment) is the only TMIC that had this in mind and they redesigned it based upon what could be done with the space allowed under the hood. (Instead of just copying what was already done. Tho in this case, I wouldn't mind someone copying PW to get the price down) Sure just driving at highway speeds constantly it works fine, but stop for a minute and its all downhill from there.

You are correct in that they can make more power (Bigger straw/more flow) but the straws are too short (cooling efficiency) for their size. (Regardless of the internal fins) A heat soaked, high flowing, inefficient TMIC sounds like a disaster in the making given the right conditions. My Perrin TMIC heat soaks like mad but I had to put it back on since my stocker started leaking. (Heat soak was much less of an issue with the stocker) The only thing i could think of to make the Perrin less heat soak prone would be to weld a tank to the bottom of the "hot" side and tap two holes and run a pump to a front radiator. (and put a ton of heat barrier material around it) A new air to air/water to air hybrid TMIC setup? Hmmmm... Maybe I'll dyno my new setup with both the perrin and the modded stocker. I'm still curious what the flow limit is on the stocker. Please remember though we are talking about daily driving here and the original point is that the modded stocker is ONE of the best for a DD stg 2 car. I think you can make an argument that the Perrin is only useful for DD'ing in the dead of winter. (In freezing temps) It plain sucks in the summer.

Exactly! (300 WHP on a VF52 is fairly easy on a MT) The turbo that should have came on the LGT in the first place.

And for you guys who use the DEI wrap. I used it on my AVO down pipe and man, it stank like burnt animal fur for a week. I think people drove in the opposite direction just to get away from the stench. It is rated for around 1700F (I'll verify) continuous which the DP should not see in a DD setup. The pop rivets on the firewall were melting from the heat coming off the CAT on the AVO DP. I eventually encased the DEI wrap in boiler conduit to add additional protection and keep the wrap from peeling off. Yes I am schooled in the ghetto Home Depot modding too. (Hangs head in shame)

Someone should be responsible for putting cliff notes at the front of these threads… The (Legacy TMIC) Universe in a nutshell… (What to take away from this thread in 1000 words or less) This has been quite entertaining and the funny thing is everyone is right on most points. There are several facts to consider most of which have been pointed out: The stock TMIC is the best for STG 2 power levels when “Bulletproofed” (VF40, VF46 or VF52 notwithstanding) The stock phenolic end tanks resist heat soak better than anything else out there The stock phenolic end tanks leak or blow up like the Hindenburg with anything more than “stock” boost pressures (or less?!?!) The Perrin and AVO designs are a poor compromise and (the designs) just plain suck. (Too short runners for their size hence their crappy cooling efficiency) They are the sole reason along with the Hindenburg end tanks that have driven people to FMIC’s that may not necessarily need them (and all the hassles that come with them) at the power levels that they are running. (I’ll throw <330WHP out there for a #. Your mileage will vary) The only good aftermarket implementation that fits the Legacy/09+WRX is the Process West TMIC with its longer tube runners to better cool the intake charge with less restriction. NOW WHERE IS THAT LEGACY SPECIFIC SPLITTER THAT WE HAVE BEEN TEASED ABOUT FOR MONTHS!!! No, you do not want to somehow use your stock endtank reinforced TMIC with that new GT35R kit. I could see that grenading the endtank in spectacular fashion. You can only suck so much air through a fixed size straw. Eventually you will need a larger straw to move more air. Seeya, I want one of your kits, please can you send me the part list or bill me. On a final note…. Can someone get the Mythbusters in here to tap a boost gauge and IAT on each end tank and blow through it until the pressure differential becomes so great that the hot side shatters? Then we will all know what the stock core is truly capable of. In either case, the point of this thread is well taken; the stock “Bulletproof” TMIC is one of the best TMIC options for STAGE 2 POWER LEVELS. Everyone please take a bow and hopefully no encore presentation. Heated arguments and unchecked sarcasm don’t spread knowledge. (Though yes it can be sometimes amusing which is an art that Rao has mastered over his million or so posts)

Don't waste your money on an IPT. Get a tranny cooler instead and wait for the better options.

They both have to be near perfect. Just that on modern day trannys there is a lot more components that they have to be near perfect on. (These are not our Grandpas TH400's or PG/TF's) The further off the mark the assembler is correlates to how long the engine/tranny will last. Anything nuclear sounds like a "fun" day job.

I'm hoping to find out the names of the places that have Trans Tech's that are the ones calling out the manufacturers on innovations, defects, improvements, etc. Those are the shops you want to use for any kind of custom work. Hopefully something will come of it and if not it was worth a try. I want to get my tranny done this year.

I used to work with someone who is now one of the VP's at Transtar so hopefuly he'll respond to my email and can help with some connections for shop recommendations, parts, and tech info. He was a great guy back in the day so hopefully I'll get a response tomorrow. CD, If things work out i'll give you his contact info and you can work with him or whoever he comes up with. (Hopefully a Jatco/5EAT Guru! one can dream right? )

I'll email a few people on Monday and see if i can get any.

^ Pretty much sums up the shock I felt after reading this thread. Thanks for bringing this to light. (And saving me some $$$) Car: 06 5EAT 37K miles IPT VB: NO As far as the 3rd question goes, I am interested in the kit since I can get a local shop around here to install it. (Less downtime since I am East Coast)I have some old contacts at Transtar and ATC that can point me to a shop that does alot of Jatco's and are reputable. (I used to do sales/support for auto transmissions for ATC/Metran before I changed careers)

One of these days i'll get around to installing mine. I asked the seller to send me the STi hose along with it so it should be somewhat plug and play for me.

I see that one from time to time in Hicksville. Never got to see the driver. (I think it's Alexxon)

My 06 STi USDM booster/MC is on the way. It looks like there is no difference in the JDM vs USDM STi booster so you are paying double for the sake of it being a JDM part.

Saw a blue 08-09 LGT pulling out of the Bulova Watch building in Queens Today around 3PM.

Whatever I pay for it. (Prob going the ebay route) Hopefully the JDM will fit and will not turn into a garage shelf decoration. (I have too many of those already) I'm going to go searching now.

I am thinking about ordering a USDM and JDM STI booster to see what the differences are. If the JDM one fits I'll be putting it on my car. Will anyone be interested in the USDM one?

No problem. You should youtube it though next track day. Need to see the stealth wagons represent. Every other legacy on there is too slow. I guess no one knows if the JDM STI booster is the same as far as fitment goes? (I guess I'll be a guinea pig)

Absolutely! Plus you win hands down on the hooked up garage.
