My Tsi project

[Duece McCracken]

I have been lurking here on DSMtuners for quite some time now. Gathering information and learning the ins and outs of my 1995 Eagle Talon TSI AWD. It's my first turbo car, and the first awd car for me as well. I'm excited to start modding it. Here's the run down so far.

Autometer cobalt Boost gauge
2.5 inch exhaust, might just be a cat-back, i haven't looked, no muffler from previous owner
KN open filter kit
New plugs, wires, and a bunch of miscellaneous maintenance items
Installed the pcv check valve.
New slotted vented rotors all way round
17" rims with brand new Conti extreme contact DWS all way round.


She runs ok, but my t25 is starting to feel weird, and im having spooling issues here and there, like no boost at all under wot when she's kinda cold. Weird things. Probably due to some terrible MBC issues that i brought about. So there are probably leaks and other shenanigans afoot. I'd rather just continue with upgrading versus fixing bugs to parts that are about to be replaced shortly

So i picked up some replacement parts

14b, with all the fixin's
1g BOV and pipe
NXS Bleeder MBC
Parts to build a BLT
New shifter cables with bearings in the ends
A buddy hooked me up with a Turbosmart dual port BOV, but im not sure if im going to run it anytime soon.

I'm waiting for
14b rebuild kit
Evo 9 fuel pump
new turbo gaskets
New exhaust gaskets.

Future purchases.

Wideband
ECMlink
1000cc injectors
Short shifter
FMIC
Tubular exhaust manifold


I do have a few questions

1. Should I bother porting my O2 housing for my 14b?
2. There's no need for an AFPR with the evo pump, correct?
3. What other items should i pick up to make my 14b happen?

I have been looking around, and reading a lot of similar threads to what I'm writing now, just thought i'd get my own personal answers finally, . Thank you all for reading, and DSM's are way too much fun!

 

[95 tsi 95 gst]

or u can see if u find a already aftermarket ported o2 housing i got one for 160 5 months ago and it has a dump tube on it too

 

[Duece McCracken]

So I ripped out the T25.

I have the 14b bolted on.

Coolant lines are good.

Exhaust will bolt right up

Im getting boinked hard by the oil feed and return lines.

14b is a banjo feed, T25 is a hardline feed. So im going to have to get a banjo end that I can thread the hardline end into, just like brakes.

T25 return line uses 12mm head bolts for the flange and has wider bolt spacing.

14b has 10mm head bolts and a more narrow bolt spacing on its flange.

I have a 1st gen oil return, but alas, it has a rip in it.

So Im I correct in thinking that a 1g return line will bolt up to the 2g oil pan?

What other options do I have for both the feed and the return?

Yes I was in the same boat when I swaped my t25 to a 14b.The 1g line was a tight fit and ended up modifying the 2g line to work so it wasnt so stiff.Also I would feed from the oil filter housing, there are list of parts you can get, or maybe contact RRE or a vender and get the parts to setup the oil lines.

 

[Duece McCracken]

Well I have the hardline turbo feed from the OFH, I may take out the 10 inch section that goes from the turbo to a coupling midway towards the OFH.

Then I will get a smaller section and a banjo bolt end, which would solve the issue completely, and without having to mailorder anything.

I have a 2g oil return line, and I actually have a 98 GST motor in my car, it was motor swapped. Just for the record, .

So I was just reading about possibly "ovaling" the mounting holes on my 2g return line where it mounts to the turbo. Allowing use of the smaller mounting bolts, and compensating for the narrower bolt spacing on the 14b.

How does this sound? Am I headed for complete disaster/failure?

In my head it seems pretty doable, any objections?

I do have the 1g 14b oil feed line, so I may feed it off the head, which 14b's were on 1g's anyway.

 

[clipto]

It really comes down to personal preference where you feed it from.My friend has been feeding it from his head over 100,000k miles, and I been running mine from the ofh.So if you feed it from the head as long as you stick with a MHI turbo you should be fine just get a plug for the ofh.But if you do the ofh just get the right parts to connect the line to the turbo and the ofh.

 

[Duece McCracken]

Im feeding from the head, and i slotted out the 2g oil return line. So it is all good on the oil, pending leak check of course.

I snipped off the OFH turbo feed hardline(with side cutting pliers, which kinks the line closed as part of the cutting process), right at the fitting on the OFH. then I removed it, cleaned it, filled the inside with JB weld, then the kinked outside got coated with JB as well. I used some rtv on the threads when I re-installed it. There is no way in hell that bad boy is leaking. Super easy solution!!!

I got the coolant lines connected. Which the return hose was kinda a pain. Luckily I had some coolant hose laying around to fab it up with.

Exhaust is connected, but i noticed one of my supports down the line is broken. i will be taking care of this later in the week.

Hooked up the vacuum lines and my MBC.

Used some MAF cleaner, and cleaned (obviously) my MAF sensor.

I have read quite a few "t25 to 14b" threads, and there was talk of just re-using the stock 2g LICP to go to the 14b j-pipe, which I must be mistaken, because it is impossible with a stock SMIC setup. A 1g LICP could work but its super sloppy and its too small for the 2g SMIC male end.

Whats the deal with that "volume" chamber before the SMIC? Actually functional? Or do most people ditch it?

I could use a reducing coupling and hack the two hoses to frankenstein a functioning one.

Any one else do some similar on a budget?

So I put in a good 5 hours on the talon today, and called it quits for now. I wont have more free time till wednesday to finish her. So im looking for some ideas on the LICP for now.

Things left to do...

Oil change
Coolant refill
LICP
hook up intake
O2 sensor swap

Um man it was a fun adveture swaping from t25 to a 14b.You should just need a lower intercooler pipe to fit from the j pipe off the turbo.Check out some intercooler places such as ETS and other vender and get a lower intercooler pipe.Don't forget couplers.

Its been a whole lot of fun doing the swap, and I have learned quite a bit from rebuilding and swapping turbos.

I think I'm going ghetto coupling for now, Im looking into getting a FMIC kit,

VRSF 2G FMIC Front Mount Intercooler Kit : 95-99 Eclipse & Talon Turbo 2G DSM

So i'm not sure that I want to drop money into a pipe I probably will replace, this is the same reason I havn't replaced my UICP yet either, its more cost effective to just go FMIC kit which comes with everything.

So i will just run whatever my crappy 2g bov can run for now, which is about 14.5 psi. Unless I drop the 35 for the 1g to 2g adapter, which is tempting...

 

[clipto]

Major plus for looking to get the fmic kit from vrspeed factory.Get it flanged for whatever you prefere 1g bov of a greddy.That should take care of your piping issue and keep your 14b cool.Not that it's all needed for the 14b but it sure gave mine some hp love, and it's on sale.

 

[SexyDSM95]

I have the VRSF 2g kit. I ran into issues with the TB elbow and had to do some cutting. I may end up using another elbow I have. Can't beat the price though, especially when the group buys come around and they are $280 or so.

What Turbo are you running?

I was wondering how it would bolt up with the 14b,

Im also still trying to use my turbosmart dual port BOV, which atm has a flange for a Mazdaspeed 3, i need to figure that out, they dont make an adapter for DSMs.

I will have to talk to a sales rep before I buy it, sort out my options for different flanges to try and rock this sexy BOV.

I tend to research alot before I buy, the VRSF kit is fantastic for the money. I cant wait to run a FMIC, for performance, and for looks.

 

[SexyDSM95]

I have a TD06 20g so no j-pipe. Tiago would be the person you would end up speaking with and he can be very helpful. I have the Greddy flange but also purchased another pipe flanged for the TiAL.

Before this (when I had my 14b setup), I actually ran a FMIC pieced together by JMFab for me. That FMIC kit is still in my basement actually have to put it up for sale .

 

[Duece McCracken]

Its cold out, and i have been sickly, so i havnt buttoned up the talon yet.

I did try to remove the stock 1g O2 sensor, which is proving to be quite a challenge, I was heating the o2 housing with mapp gas and it still wouldnt break free. What a pain in my testicles. So im soaking her in PB Blaster till my next attempt.

One of these days i will have her running again, .

 

[dsmlover94]

did any of you guys have problems mounting the vrsf front mount?

The acual core? Or the kit in general? I had a hell of a time with the TB elbow, that was pretty much it. I pointed it out with pics in the latest GB thread.

[Duece McCracken]

I got the O2 sensor out, but it mauled the sensors threads upon removal, so im going to chase the housing before I install my freshie sensor.

Whats the thread/size of O2 sensor bung? My buddy has every tap known to man, I just don't know what size it is.

I decided to sell off some of my unused firearms, which just put 900 into my talon fund.

VRSF FMIC here I COME!!!

Also looking into DSMlink. I have to check my Ecu out to see if its EPROM. Which it could be, I have a 98 motor though, so I hope the ECU was kept from the 95.

So pending on how this all goes down, I will have FMIC, one of my better BOV's installed, and DSMlink. Then i need a wideband, and I want to ship out my shifter to Dogbox.

Is a wideband needed to tune with DSMlink? I'm talking rough tune just to have her running safely and reliably. I know I should be looking it up right now, but i figured I'd go the lazy route in my own thread, .

I agree, heatsoaking is not good. I also would get a cosmetic head gasket when running 16-17 psi or higher.

cometic? head gasket you mean? id say the 1000 CC injectors are overkill for a 14B, also a 1g j pipe or SMIC i would think doesnt work in a 2g..

the 1000 cc injectors would leave room for future upgrades, I'd rather buy one set of 1000 and use ECMlink to control them, then keep buying slightly bigger injectors for every turbo upgrade I do in the future. Im running the stock 450's for awhile.

Im not using a 1g SMIC, I just stated that my buddy gave it to me with all the rest of the 1g 14b parts. I never had any intention of swapping into my 2g. No need to at all.

The j pipe can be made to work, but it's ghetto.

Anything else?

i just stopped reading the thread right about at the throat cutting... but think about things this way.. how much power do you plan to make. plan for your goal. if you plan to get a 16G or bigger or upgrade your pump to something else why not just buy studs and AFPR.. doesnt mean you have to buy it all at once... but buying the parts needed for a solid build cant hurt. id say do it right the first time ... instead of doing it right the 2nd or 3rd time. just my advice. i just finished building my 99 GSX.. 6 bolt with ARPS the AFPR was actually the last thing i bought and have yet to install... so to each his own and good luck, OP, once you feel good power you will get addicted and want to go faster, if i were you i would buy what is neccessary instead of going the cheap route.. weather you are a college student or not you can buy in small portions.

Edit: after seeing your response to my comment about the 1000CC injectors... it makes this post even more true for you. im the same way.. go big or go home... make a goal and work twords it. for some people it takes 5 months, others 5 years.

vrsf is a good fmic btw i have one and its holding great. you will have to cut the radiator support, as well as take out your EVAP can.
i do how ever think that if you dont plan to make more then 500 hp you will by all means not need a dog box.

I hear that, Im ordering my FMIC kit tomorrow, which will eliminate any ghetto rigging with the intake pipes.

Im pulling my Ecu and getting ECMlink very soon as well.

Already upgraded the fuel pump.

I took the Talon off the road, I'm taking my time and getting all the parts I need. Working on it with no rush at all.

My main goal is to make smart purchases that will work with bigger turbos. So far I believe I'm doing a good job.

I'm hoping to squeeze 250whp out of the 14b. That's my first HP goal. I'm also going to be self tuning. Which I'm excited about.

Im not talking dogbox tranny, their shifter setup has caught my eye.

 

[Archer Fabrications]

thougth you were talking about the gear box. if i was you, id get a 16G for 250 and save yourself buying a 14B and a 16g later... you can always set lower boost. i was like you having one hp goal for now and then one down the road.. but why not just shoot for the one down the road, i was going to go from a stock T-25 to a 14b stock build, then i wanted a 16G which was the frist turbo i actually bought.. but before i installed the 16g i was like Fu(k it, all or nothing, sold it for 400 and picked up a PTE 6152 Dual ballberring and now after my tune ill be in the neighborhood of 500awhp so its up to you, if you want to make smart purchases id say definitly do it.. and buy parts for hp you plan to make later... a 16g isnt going to get you that quick without some crazy weight reduction and other goodies that arent going to be cheap. you can slap on a 50 trim and not strain the turbo as much if you want a conservitive 300hp you would already have the fuel setup to support a 50 trim so why not.

 

[clipto]

Yes the 14b would give you 250whp easy with about 16psi I made 240 at 14psi on a 14b with safc 550cc and a 255 pump, but remember I am fwd and auto.The 16g is a much better upgrade and it made a huge difference even at 10psi compared to the 14b, but eather way you go they work amazing.

 

[dsmlover07]

Not bad, nice list there for your dsm.

 

[4g63dreams]

I love reading build information but I get lost with all the jargon abbreviations and it doesn't help that I know nothing , I guess I will learn by reading. Never touched a wrench... But its extremely inspiring to read this stuff so please continue writing it.

 

[Duece McCracken]

Don't worry, all my triumphs and heartaches will be well documented here!
I'm here to learn, and show others what I can.
