Don't have the TMIC yet, but would like some better install instruction then what comes with it. Thanks.

pull OEM TMIC, remove rubber ring around end of throttle body hose, insert Perrin TMIC, turn all screws and bolts clocwise that were previously turned counterclockwise. Either I'm a d!ck, or it's really that easy. You be the judge.;)

I've had the oem off....it was easy. Just I've read some posts that gave me the idea the Perrin wasn't that cut and dry.
I guess #7 confused me a little...."caps"?

#7 = "remove rubber ring around end of throttle body hose" from my cliff notes;)
I don't remember taking one off the throttlebody side, but I did remove the one on the TMIC side. It's not a cap so much as it's just a rubber adapter ring that cushions the hose clamp.

It is easy, but do yourself a favor and grap a T-bolt clamp to replace the screw clamp. $5 is well worth the peace of mind.

You got lucky!
Some of the PERRIN's do not fit well... Be warned now that the flange on your PERRIN and the flange on the turbo outlet may not look flush.... Mine has a 2mm gap! But once you tighten it down it seals....
Good luck getting your stock brace back on... I'm pretty strong and I had to muscle it. (I also have a huge BOV)
TIME: less than 45 minutes

Just install it already.:lol: When you put the TMIC inplace, the harness clip they're talking about may or may not need to be trimmed. Either way, it will be obvious what the obstruction is and how much needs to be cut if any.
If you have an after market STB you may run into fittement issues... I did with the STi STB.
nothing 2 small washers couldn't handle!

You can run a TMIC with no map update

^ yeah, just figured I'd do it all at once.

you'll run slightly lean.... be aware.

^ hmmm.
I want to get this thing on already. I won't have an updated map from TDC until next week as Mike's mother passed away yesterday.
oh, btw...found this walkthrough which includes the removal of the oem intercooler.

Can you edit out the first 15 posts and sticky it?
You'll be fine. It's not gonna run so lean that you do damage.

I just got done doing mine a couple hours ago and noticed the turbo side gap. Both ends where the bolts are touch, but the middle is a little high. I had to put a big washer on the brace bolt to get it to clamp down.
I took it out for a spin and it ran great in 1st, 2nd and 3rd, but I think I got some WG flutter in 4th and 5th. I don't know if I had a hose leak before or what, but the boost comes on a lot quicker and holds better, but I'm getting a "click-a-click-a-click...." when boost gets above 15psi in 4th and 5th.
Is it time for a new actuator too?

My perrin didn't want to naturally fit snug in it's spot either, I def had to use some extra time and energy to get it in place and screwed down.
Hopefully I'll have no leaks or other issues. I don't want to have to take that thing off and put it back on again anytime soon.

After you do it a couple dozen times it gets easier, but I hear ya. Mine was a real pain at first. It definately doesn't just "drop in and bolt up"; there's a little coaxing that has to happen. Once the transplant "takes" and stays on a while it seems like it comes apart and goes back together a little better. The rotation on the IC->TB hose seems to make a big difference on how it lines up with the turbo.
Just a note guys,
Be carefull bolting down the turbo side. The flange is made of aluminum and strippes real easy.
I know, I stripped mine :(

I just installed the Perrin TMIC last night for the first time. Can someone tell me what the point is to step 7 (where you remove the rubber caps from the boost tube) in the instructions?
I tried it with and without the caps and reused the caps on both ends. Works fine with no leaks, I just don't see the point in removing them.
Now what is the biggest LGT style turbo I can run with this and Meth?

Theoretically the Perrin TMIC is good for up to around 400ish crank HP without meth and just a bit higher with it. I'll be putting a DB 20G Zilla under mine in the next couple months and hopefully it should put down around 330whp. You can use any turbo that will fit, but you just won't be able to max the turbo out with the TMIC and meth if it's any bigger than a 20G, 40BB, AVO420... after that you need to go FMIC. Of course no matter what you will have more heatsoak on the TMIC as the turbo gets bigger, so wet injection is almost a must.
The point of #7 is so that those end pieces don't slide off under higher boost levels. I left he one on the TB end, but removed the one on the IC end. 6 of one half a dozen of the other. I've never had that hose blow off either with or without the end rings on it.

Take them both off, IMO. I would repeatedly tighten up the clamp on the TB side with that cap on, and it would always develop a leak under boost until I took it off. I have blue stains from the washer fluid all over that side of the block to prove it:lol: kinda like Fletch.
As for turbos, RC is running a 20G with meth and the perrin, bosco has a 380 and meth, but is on an AVO TMIC I believe. I run a 40BB with meth and the perrin. All three turbos seem to run healthy in their respective setups.

Would you consider an AVO 450 doable with a TMIC and WI? I don't care if I have some lag, I just want the most top end pull I can get with a TMIC.
I would live to take a road trip up north some weekend and get a ride in a few of these cars. I know I will see a few of you at track days and I know that will motivate me to spend some more money on mods
edit - Oh yeah, who thinks they are the quickest?

I don't know much about turbos other than my own. I'd ask Rallitek about the 450 specifically.
I believe TRS and I are both signed up for the AMS event in April at Autobahn, full course, and cheap. You should try and make that one.
Oh yeah, meier motorsports thinks he's the quickest, but in reality, BoxerGT2.5 is likely the fastest.

any pics of these rubber caps or boost tube? i installed my perrin and completely skipped that step. pretty much just took off the stock one and slapped on the perrin.

I installed mine on a lunch break...and I am not a mechanic. Be carefull though, I did later go back to put zip ties ont he t-connector (must do this) and ended up stripping out a turbo bolt!
use some hard grease to keep the o-ring in place while placing the TMIC.

is the t-connector the rubber caps they are talking about? i still have to put some ties on it but it hasnt blown off yet

It is a blue T-connector. Once you go stage 2 and higher boost. It may eventually blow off leading to rough idle and loss of power. It happened to me, it could happen to you. Someone took some good pics, I'll try to find the thread.

rubber caps are on the ends of the hose that connects the TMIC to the throttle body. I believe Perrin recommends you remove the cap on the TMIC side, but the one of the TV side also gave me problems until I removed it.

ive played with the t connector but i still cant picture these rubber caps. ive taken this thing off like 4-5 times now. should i bother to go back and check it or is it just so it fits in easier?

They're just sleeves on the end of the rubber hose between the TMIC and TB. They pull right off the end, once that end of the hose is freed up.

i think mine were already off. maybe the dealership removed mine when they replaced the turbo 25k miles ago. unless they are inside the hose

Anyone have pictures of how the throttlebody hose is supposed to sit. For the life of me yesterday I was trying to get it to sit correctly and it wouldn't and so my TMIC wouldn't line up to the turbo outlet when connected to the hose or vice versa

Any luck on finding those pics? I have a feeling I may need to fix this because when I installed my TMIC i skipped this step too..

Here are some pics of the blue t connector/adapter that I believe you're talking about. I took these while trying to diagnose a #3 & #4 misfire. ugg... what a nightmare.
The hoses did not seem loose, but I zip tied them anyway while I was in there. Doing so does not seem to have stopped the CEL and misfire.
