What'd you do to your FIRST Gen. Subaru today?


Recommended Posts

Subaru factory boost controllers are known to be horrible, just running the same boost with another boost controller yields results. Also, Did this on a friends cobb stage 2 06 wrx and it prevented overshooting of the boost at too low of RPMs.

Journey inside 22T heads. http://i301.photobucket.com/albums/nn41/henry616/Mobile%20Uploads/8BD8C567-DC23-4918-8B01-0AFAC0CBE10A_zpsznikgeaw.jpg

Remove two 10mm bolts and one 12mm to remove cam cap and slide the camshaft out.

Stamp on the inside of head. http://i301.photobucket.com/albums/nn41/henry616/Mobile%20Uploads/D6CF3F43-47CE-4E03-9D21-5AE0611C91BB_zpsoj5hcgqj.jpg

 

I hope this head enjoys it's life as a future soda can.

K. To keep it simple then, what are basics I'd need for just a simple td-04??? Since they pop up all the time for under100$ or say a 16g? I wouldnt really push more than 10psi, so I'd assume 440injectors is about all that's necessary, MBC, dp(can easily get for under 125$), and I already have a borla hush (3inch) awaiting install. Sorry but BBS gets bumped maybe a few times a month for answers.

If you change injectors you need an EJ20G ecu. If you change the turbo to anything other than a TD04 running 10 psi you need a lot more shit than you have any idea.

 

Stick with the stock turbo for now, get a Hallman MBC and an intercooler to give yourself a few more pounds of boost, and start collecting parts.

I think this is one of the best posts on bbs to install a tmic and turbo. The OP installs a td05 but it is the same procedure for a td04.http://bbs.legacycentral.org/viewtopic.php?t=38598

 

 

A Forester XT or 06 wrx tmic are a direct fit. You could use an 02 wrx tmic but you will have to shave the TB or bash in the firewall.

 

GTeaser, how easy was it to set your mbc to the correct psi? I have an ebay mbc that was recommended to me over on bbs and it was only $30, but I don't think it will be as easy to set as a Hallman.

The TD04s are a great upgrade on those. Had that and a WRX TMIC in mine when I left it. .

 

Can you elaborate a bit on your impressions after the swap? I've heard anything from "I hardly noticed a change" to "it rocks". What psi were you running?

 

I have almost everything for the tdo4/tmic swap but haven't had the time to do the install.

Yes, the 06-07 WRX and 06-08 XT intercoolers should work, but not a "direct fit". It takes a little ingenuity for the plumbing changes and little adjustments to many hoses, lines, etc in the engine compartment. There are some walk-thrus on BBS to help.

 

The Hallman is a high quality piece. Beautiful finish, smooth operation and easy install. I got the ProRX which has the ceramic ball vs. the regular Pro which uses a stainless steel ball. I got it for $90 shipped and it was well worth the extra $. You can find the Pro for $75. Adjustment was super easy. I found a thread that said 7-8 turns +boost will put you around 10psi and sure enough it did. 7 was 9psi and 8 was 10psi, so 1 turn per psi in that range. My boost gauge isn't super accurate (it reads about 1psi low) but I have read numerous places that the Hallman is so good you can easily dial in boost in 0.5 psi increments, and I would agree that that can easily be done.

The TD04 is pretty much just a stock replacement, so if the old VF11 takes a poop, a TD04 is a good, inexpensive, readily available replacement that will work as stock with all the stock equipment. I think the reason we are hearing that kind of range of feedback from "cant tell" to "it rocks" is because guys are either just replacing the VF11 with a TD04 (hardly any difference) or making other changes at the same time (like MBC, upping boost, adding a DP, etc) and of course they are going to notice a difference. I upped the boost 2psi on my little VF11 and noticed a pretty big difference and would say "it rocks", so I am not sure that the feedback we are getting is not apples to apples and is getting tainted by other mods that are being done at the same time.

 

That being said...a slow, steady, well thought out mod path is critical in ascertaining the real world performance improvements of each and every modification. This is what I plan to do...a step by step approach so that I can really understand each and every improvement to the car. For me, the downpipe is next and then following soon after the full exhaust. I want to see how that addition spices up the turbos response and spool time. And then on to more psi and an intercooler.

By direct fit I meant you don't have to take a hammer or hacksaw to get the tmic in place. Thanks for clearing that up!

 

I agree, doing one mod at a time is the way to go. Not only for troubleshooting, but to really get a feel for each improvement.

 

I'll have to install the mbc and see what happens! Too bad my prosport gauge took a dump, so I have to get that fixed before I go upping the boost. I bought a new sender but that didn't fix the problem.

Extracted another 22t cam. It was super fun to pull them and a lot easier than I expected. Pretty clever design. Interesting how one is quite a bit smaller than the other, reason being the placement of the cam sensor. 167k on these guys and they turned so smooth. More evidence of the robustness of the ej22 design.

Good vs collapsed HLA. It's a good idea to replace them! ;)

FP green should be a lot of fun. I have my eyes on a 16g or 18g.

 

New OEM crank & rod bearings arrived yesterday. Time to scrub out the block and do a practice assembly before I seal the case halves. I need to clean out all the threads too. I have a good sequence to install the oil squirters. Bottom out the threads w/red lock tite and then another 3/4 turn! :)

This is what four EJ22T B pistons w/167k look like. :cool:

Wrist pins were clean as a whistle.

The OEM 22T pistons have tiny valve reliefs. The relief on the right side is hard to see. They are also amazingly clean for how many miles are on them. Stock 22T ecu must be pretty smart.

Next to Wiseco 22T pistons.

Wrist pin placement looks to be close. Oem 22ts have a longer skirt.

The Wiseco valve reliefs are a little deeper.

I had my 22t block bored for the Wisecos. But after checking out the 22t pistons I realize I could have ran them no problem and saved a bunch of money, lol. I thought it was cool how they are all Bs. I wonder if all 22ts have matched pistons.

had engine in, realized the flexplates different btween turbo and non turbo....good practice I guess. Got the vf 34 in there, space is a little tighter, and wrapped it, spt heat plate will go on after I check for leaks. down to the oil catch cans. There isnt a whole lot of room, and I want it to be neat and tidy, a task that is proving to be difficult.

Ya no joke. Super hard to keep clean. Anywho; I guess what I did to my first gen today wasn't good. I've been burning oil the past few days & idk why. When I shift it spews or if I take my foot off the gas & let the motor slow me down in vacuum it burns as well. I was running Havoline syn 10-30. Since Im burning (about 2k into oil change) I decided to do a flush & change since I also had a small lifter tick. Doin this on my n/a car always fixed tick. The gunk md3 said not for turbo diesel... well some1 told me its bad for any turbo car... Well shoot!!! Anyway I put in the Pennzoil Platinum as its coming out w/ lowest wear results of any store bought syn u can get. Still smoking but not as bad. Also runnin Motorkote additive. I am thinking of running a Delo 1540 is there any adverse effects such as the gasoline, mixing with the diesel oil breaking it down? Ideas? Rings? Turbo seals?.. haven't checked compression yet.. will. Also vacuum guage used to read 20-22 now its 18-20... makes me think rings.. idk. Could be pcv related but its pretty new. Also in my catchcan there's yellow baby diarrhea lookin stuff smells kinda like gas? And no I'm not usin coolant. Have new Cometic mls head gaskets Edited by Abeall2

Smoke on shift and decel usually indicates valve seals/guides. Or, since you're turbo'ed, it could also be the turbo bearing seals. There's probably not much you can do about either of those other than running a heavier weight oil like 10w-40.

 

Keep an eye out for a inexpensive replacement turbo in good condition that you could swap in if you wanted a little weekend project or were in a pinch if your current one fails. It should be fairly easy and will help you narrow down the problem to either turbo or valve seals.

You said you have cometics? Supposedly you need mirror smooth surfaces for them to seal properly. 50 RA. http://www.cometic.com/technical.aspx but fwiw I asked my machinist what the RA value was on my block and he had no idea what I was talking about.

 

Did you have the heads and block decked before you installed them? My buddy was running cometics and they blew right away. Others have used them with success though.

yeah, i want to upgrade to A TD04, I am not sure which brand is the most cost effective for brand of turbo. Fastest spool etc... If anyone knows the best turbo upgrade for the money let me know

Stick with a small exhaust housing if looking for quick spool, so I'd suggest nothing bigger than 7.

I really want a td05-16g but don't see that happening or vf28 I believe is a JDM turbo..probably wrong I can't recall the #it is.
