westy66 Posted September 30, 2008 Share Posted September 30, 2008 i just finished my install a couple hours ago. after reading all the horrors prior to the install i wanted to post my impressions and method. -Remove 4 pop-screws from engine cover http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001666-1400.jpg -Throw cover aside http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001667-1400.jpg -Remove two bolts on turbo side http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001668-1400.jpg -LOOSEN two front bolts on green TMIC support bracket on manifold -Remove one back support bracket bolt from TMIC -Nudge support bracket out of the way and remove two recirc valve bolts -Loosen large clamp on throttle body http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001670-1400.jpg -nudge the recirc valve and green bracket out of the way and wiggle the stock TMIC out http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001675-1400.jpg -WOW either the stock TMIC is small or the Perrin is BIG http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001671-1400.jpg http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001674-1400.jpg -heres where you might want to put zip ties on the "Blue T" hoses to prevent possible blow off. -coat your finger with a little assembly lube, oil, whatever and lube up the inside surface of the throttle body hose (large black one) -install the provided o-ring into your new TMIC on the turbo side. shove the Perrin all the way into the throttle body hose and SLIGHTLY snug up the hose clamp. -reinstall the recirc valve with its two bolts. http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001676-1400.jpg -so now the only two things connected to the new TMIC are flexible (this is important) -wiggle the TMIC until you can get the turbo side bolts lined up and start them. BE CAREFUL, your threading into alluminum!! tighten about half way. http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001677-1400.jpg -hand tighten the back bolt on the green bracket to TMIC. http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001678-1400.jpg -start on the turbo side and tighten those two bolts about 2/3rds. tighten the green bracket bolts a little. alternate side to side now. you might have to push the TMIC over from the passenger side to get it to sit on the turbo. this is the side you want to mate first. http://img.photobucket.com/albums/v486/westy66/TMIC%20install/IM001679-1400.jpg Youre done! only took you 30-45 minutes!

autotech Posted October 19, 2008 Share Posted October 19, 2008 do you need supporting mods or a tune for a top mount. i have a chance to pick one up (perrin) for 350 or so. but i dont have a tune or a downpipe or anything like that. Link to comment Share on other sites More sharing options...

Guest LGT-NY Posted October 19, 2008 Share Posted October 19, 2008 (edited) Nice walkthrough westy. Here's mine: http://i211.photobucket.com/albums/bb93/bpotts1/2878028346_0343ef3208_b.jpg Edited October 19, 2008 by LGT-NY Link to comment Share on other sites More sharing options...
Guest LGT-NY Posted October 19, 2008 Share Posted October 19, 2008 I also found it helps if you removed the plastic hose bracket between the manifold and the TMIC, it gives you a little more space to work with and allows you to align the IC more squarley.

SBT Posted October 19, 2008 Share Posted October 19, 2008 Thanks Westy - Nicely done! So the engine cover will not fit with the Perrin TMIC installed? I'd heard/seen this on the earlier versions (3-4 years ago), but haven't been watching recent improvements. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...
Guest LGT-NY Posted October 19, 2008 Share Posted October 19, 2008 You would have to trim the engine cover quite a bit to get it to fit. It's been done. Link to comment Share on other sites More sharing options...

fishbone Posted October 20, 2008 Share Posted October 20, 2008 If you don't put the engine cover on, there is about a 2-finger gap all around, depending on wether you have lady fingers or chubby fingers. Eitherway, I'd say the air isn't forced in the TMIC with the lack of an engine cover but I can't say my boost or intake temps have been adversely affected noticeably. There's a debate wether or not to put the engine cover back on, some do, some don't. I haven't modded mine yet but I plan on putting it back on.

westy66 Posted October 28, 2008 Author Share Posted October 28, 2008 (edited) UPDATE: the Perrin was rubbing sporadically on my clutch cylinder clearance to the cap is about 1/8" - 3/16" - but i can still get the cap off. i remounted the TMIC ABOVE the green support bracket on the Left side. no more rubbing. the clearance didnt change, but since mounting the IC over the bracket the twisting motion of the engine under load doesnt push it into the cylinder NICE!! i can get my hand into the scoop and can feel about an inch gap between the TMIC and the boot on the underside of the hood. i cant see how this could possibly effect cooling at any speeds over 20 mph as the boot is so focused on the intercooler. the only downside i can think of is now rain, snow, salt, crap can more easilly blow over the back of the IC.

ripsweetness Posted November 2, 2008 Share Posted November 2, 2008 Perrin is now selling there TMIC for $499. Im thinking of buying one and simply keeping it in the box incase my stock ic goes. Link to comment Share on other sites More sharing options...
TPLGT Posted November 2, 2008 Share Posted November 2, 2008 Without the engine cover properly installed, you will lose major WHP. Also, dpn't fprget not to get soap in the intercooler when washing. Rehab is for quitters. Link to comment Share on other sites More sharing options...

SBT Posted November 3, 2008 Share Posted November 3, 2008 ^ not sure but think the "major WHP loss" was a tongue-in-cheek comment. Seriously, can anyone post up a picture of the "trimming" that needs to be done to make the engine cover "fit" the P-TMIC and what's the best approach/tool to use for the trimming. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...
TPLGT Posted November 3, 2008 Share Posted November 3, 2008 yes. Tongue in cheek. A write up would be nice. I got my cover from another memeber. It is just the front half of it. Rehab is for quitters. Link to comment Share on other sites More sharing options...
GULLABLE0NE Posted November 3, 2008 Share Posted November 3, 2008 nice write-up. i'll be subscribing to this one since i bought the perrin tmic the other day since it was on sale for 500 bucks. Link to comment Share on other sites More sharing options...

SSpeed Posted November 7, 2008 Share Posted November 7, 2008 (edited) With the engine cover off you lose pressure on the front of the intercooler possibly not forcing air through it... I did a little more "sealing" after reading this article... interesting reading... http://autospeed.com/cms/A_109440/article.html Jist of the article: "Outside air will only flow through the intercooler core if there is a higher pressure on one face than the other. In other words, there needs to be a pressure differential across the core before any air movement through the core will occur. So the fact that there’s a forward-facing scoop over the intercooler, and that the air pressure builds up on one face (as described above) is actually not the real point. It’s quite easy to have a forward-facing scoop that connects to the intercooler, but to still not have any flow through the intercooler – or to even have a backwards flow, where hot air from under the bonnet passes out through the intercooler!"

TPLGT Posted November 7, 2008 Share Posted November 7, 2008 It's BS. If you log before and after, the numbres are the same. It makes no difference...the cover is only for aesthetics. Rehab is for quitters. Link to comment Share on other sites More sharing options...

SSpeed Posted November 7, 2008 Share Posted November 7, 2008 It's BS. If you log before and after, the numbres are the same. It makes no difference...the cover is only for aesthetics. What specifically are you logging to show it makes no difference? Unless you can log IAT in each end tank, as well as pressure on each side of the intercooler you can't say definitively that it's the same cover on or cover off. There is nothing in the engine management that measures efficiency of the intercooler. The engine cover provides a direct seal against the intercooler, with it off air can follow the path of least resistance. Probably one of the reasons the bottom cover is there as well...

HansGT Posted November 7, 2008 Share Posted November 7, 2008 do you need supporting mods or a tune for a top mount. i have a chance to pick one up (perrin) for 350 or so. but i dont have a tune or a downpipe or anything like that. ^ then why bother? If you have no other mods the stock IC is fine. Link to comment Share on other sites More sharing options...
