Was having some issues with the fuel pump and regulator. The gauge was reading different pressures and the car would shut off if I turned on the external fuel pump. I wasnt happy with the way the 034 fpr adapter sat on the rail. So I ordered a USRT intank pump and FuelLab adjustable FPR with a new pressure gauge. Hopefully, this will help with the issues and I can finally start tuning it!

- cam tensioner tool, gasket, half moon seal, and valve cover gaskets will be in today. I should be able to get it done tonight or tomorrow and have things ready to drop in the fuel pump and FPR when it gets here.

fixed the half moon seal today! super easy with the depress tool

Been tryin to get these little quirks sorted out. Fuel system has been acting up, so I decided to start fresh and get it right! I had been wanting that I tank for awhile and finally had the means to do it!

Yea, the genesis intank pump is nice, and works well. Pretty reasonably priced even compared to an oem replacement. What kind of problems are you having with your fueling? I included some USRT vinyl in the package so you can rep it in the OK

[18T_BT]

seth-i'd remove the gasket for the WG...I haven't run one since I blew out the tial gasket on my pagparts mani and no leaks without it the gasket...yours does look better then what tial use to supply:

keep the gasket! i wish i had pics of the 2 wastegate gaskets i have. they are stainless steel and heavy. almost like a mini flange. theres no way anyone could blow one of those out. i'd have to see it to believe it

[Big_Tom]

for the longest time slowboy racing had a $hitty website. it seems like they have their site together better now and these gaskets are now listed. They are local to me, i buy all my t3/wastegate/turbine housing related gaskets from them if i can.

check out their t3 turbo inlet gaskets as well

You know I'll rep it! Well, I could narrow it down. I had the inline JEGS gauge ad kept getting a variated reading between 80-100 psi with only the stock pump running. If I turn on the external it would kill the engine. I was thinking it could have been the regulator, but the pump wasn't priming when I opened the door either.. So, I decided to hardware the pump. It would come on and the car would run (although lean, this is why I was confused. If it was running at the 80-100 psi it would have to be rich). I had an adjustable drop in fpr. It was a bitch trying to get a good vacuum seal on the nipple as well. So being fed up I decided to get a new pump (so I could pully the external for awhile to eliminate that variable. Get the fuel lab fpr and your pressure gauge so I know things are working properly. Getting those fprs in the 034 adapter was a bitch and I was afraid I would break the fpr or alter the pressure of it with too much force. Also I bought the Ecu used. With VCDS I noticed the Ecu had an 870/R4 signature on it.. If it truly is 870 then I'm running these injectors it could explain the lean issue and a faulty JEGS gauge would explain why it ran ok even though it was reading extremely high. If it was 870 file then I would need a lot of tuning as well to get a good idle/part throttle. I said **** this. I will get a new easily adjustable fpr with a good gauge and new pump because it puts out so much more and could run without the external for a bit and add it on later. With the adjustable fpr I can get my idle AFRs in a good region. Then, Run some logs to make sure it's good through the rest of the band and due minor adjustments through Unisettings to good a good curve and timing.

-WG gasket is on the bottom of the list right now. I want to get the fuel system taken care of first. Then I'll seafoam it and if it's an issue I'll be back to hear some suggestions since we already have varying opinions on the posts above.

Sounds like you got it all figured out. So you think you have a Unitronic 830cc file? Give me the ECU information if you can and I will look it up in the database. I should be able to have an answer for you. Did you buy the ECU off the original purchaser of the software?

[seth_3515]

I think I have an 870 file and 849cc injectors (racetronix) it would explain the lean issue, but I thought they didn't make an "870 file". I'm not 100% on this though, I never searched enough to see where the 870/830 file as far as existence and time frames. I'm not sure if he was the original owner or not. I'll get you the signature on it though. It would really help me out to know so I can have more clues to trouble shoot problems.

[wrestler4life521]

Ive been following your thread on grass city. Small world.

[seth_3515]

Anyone know a reputable unitronic tuner in states bordering oklahoma? Considering taking it to someone for the first tune and looking for suggestions

[zrau17]

I use Cometic gaskets, I kept blowing the normal thin steel ones. Since the Cometic switch I also use high grade flange head bolts with nordlocks.

[seth_3515]

USRT fuel pump and fuel lab adjustable fpr came in today! Have tomorrow off so I'll be doing work to get it going. I'm hoping the second muffler comes in today so I can get it welded tomorrow after its up and running.

[seth_3515]

Finally got all the fittings and got everything installed! It's running much better as well! I can definitely tell a difference in the idle and ability to stay at idle without jumping around. Unfortunately, injector number 4 needs a new oring more time but I can definitely see the potential of the engine. ordering the oring tonight with some spares, then pressure test intake again tomorrow. Patience and persistence is starting to show results.

Got a vac leak at the injector!! I could hear the air escaping and kept looking for it. It sound like it was at the fuel rail and I was getting perplexed. Finally I noticed the injectors and thought it could be it. Poured a small amount of water on the base of the injector near te manifold. Sure enough it seemed to "gurgle" just a bit. I had an oring and put it in. I didn't have time to retest the intake but will be doing that this morning along with putting resistors on the N112, N249, and N80 so I can get my fuel adaptation back and get it running even better. In a perfect world I should be done with the car by noon (starting at 10 when I get off work) and get to a muffler hop to have my muffler, and exhaust hangers welded this afternoon but I don't know what time they close for sure so we shall see.

-did a spirited little pull from 1-3. I must say I was happy. It spiked around 15psi and is averaging around 11mmhg of vacuum at idle. After letting off the gas to a corner, it still stumbles a bit to find idle and maintain the 11mmhg. When this happens it starts around 5mmhg, bounces between 5 and 11mmhg before maintaining it. I think it had to do with the small vac leak and the Ecu not ring able to adapt the fuel. Hopefully today will solve that and finally be ready to get her on a dyno and do some tuning.

[seth_3515]

Little update: Finally was able to seal the injectors up. They needed to be raised a 1/4 inch or so. Oem exhaust manifold washers worked perfectly My AFR's dropped drastically right away. Before, the car would idle very rough and of course never hold vacuum. Now, it searches for a second or two to find the sweet spot. Its nice to finally have it idling so smoothly and its holding 15mmhg of vacuum at idle now. I want to pressure test some more and then Ill be starting to tune it.

-The first pull after the leak was fixed was awesome. It pulls hard and is very manageable. I was running of WG spring and spiked around 15psi. The car feels a little rough at part throttle but in boost it feels smooth. Ill be trying to get it to run a bit better at part throttle and I think the tune just needs a little love and itll shine.

-The suspension upgrades helped the handling immensely. The ST coilovers got me to a good height and were easy to install. They seem to ride very well for a quality "budget" setup. The rear spring could be rated differently. I think I may get some different rated springs to try out. I havent got to drive enough to get a better idea on how much. I plan on following the old madmax thread on the suspension of the TT and try it his suggested spring rates along with 2 other pairs (one rated a little lower and one a little higher) to see what fits for me best.

-USRT tubulars- Fukin ROCK! These control arms honestly give you a much better feel of the road. I wish I could put it in to words better but here is my attempt to give an example. -These control arms offer smoother and "longer" articulation of the wheel. First thing i noticed was on a decline exit curve. At a good rate of speed (not speed racer fast, but the passenger clinched the door and was trying to hold on), I went into the corner. The outside front wheel actually felt planted. As I came upon the apex, the weight of the load increased on that tire. The more the load increased the more a could feel the tire's contact with the road. It never felt like it was on the brink of breaking loose. It felt like it just planted more and more. The control arms definitely give much more feedback from the road and tires. I received a lot of pms asking about them and I would highly recommend them to anyone considering them. With the car running much better now, Ill post more as I get more seat time.

-Wavetrac LSD- On spirited pulls, I wasnt getting any torque steer at all. I had some low rpm 2nd gear pulls. When the boost came on, the tires would give a good long screech but not actually break completely loose. I wasnt trying to break them loose but wasnt trying not too either. At 15psi it makes for a very, very manageable and streetable setup. I also had the 5th gear changed to a TDI gear. This made a big difference in highway speed RPMs. When I was talking to Gonzo he said he wasnt sure if the cruise control would work with the TDI 5th gear (not trying to start **** but im sure others have/had the same questions). My cruise control still works and would recommend the upgrade to only those who drive a lot of highway miles.

-USRT fuel pump and FPR- I had some weird issues in the fueling department. My drop in FPR or gauge was off, my walbro was acting up, and wasnt getting consistent pressures. I scrapped the whole system and went with the USRT Genesis intake pump, FuelLab adjustable FPR with gauge, and all -6AN lines. This made a huge difference! It is extremely easy to adjust the fuel pressure and keeps it very steady. All in all it was worth every penny and really simplified the setup. When the time comes I will be adding a surge tank, but the beauty is I wont need one for a little bit til I start really raising the boost pressure and start making serious power.

- IE and PAG parts dont need a review IMO. The only thing I am kicking myself for is not waiting a little longer for the Vband set up All the other parts have held up and I have been very happy. DP fits, turbo manifold was easy to install, WG lined up with the dump tube as well. We all know these are tried and true quality parts so I wont spend much time on them.

It's been awhile but I have been busy with work, school, and life.. Anywho the car was driving good on 15psi. Wasn't the est tune but I didn't have everything done the way I wanted it. So here it is again, a very long build thread. The more I do, the more ideas I get.. Unfortunately I don't have all the tools just yet to do what I really want to but soon enough

New items
- supertech springs, retainers, and valves in a cleaned, decked, and ported AEB head. All being done at the local shop. I've developed a good report with the owner and he was very knowledgable and seemed worthy..
-I went with ehlring on all the gaskets
-ordering an IE camshaft gear for the AEB on Friday as well as a gates timing belt

The plan is to get the new he's finished and installed on the car and make sure tuning is acceptable to atleast drive the car at 15psi. At this point, I will dig a little deeper and get the fluidamper and IE surge tank with an 044 since I am only running the USRT for the time being. I didn't dyno the car last year but I plan on getting it there this year. I am actively pursuing the tools to do a tubular front radiator piece. The black plastic is getting in te way and I could really benefit myself to do it. If any body has some tips on this please lmk!

Talk to Luis A267mm. He was having a shop build a tubular radiator support out of aluminum.

Really? Thanks man, I really appreciate it. I'll message him

[pete@integrated]

before I tear into the head..

can the Tial 38mm wastegates be torn down to move the bottom port to the side? its a pain in the ass and touches the valve cover. Heres a quick shot while I was taking the valve cover and **** off to do the half moon seal.

Yes, you can- there are some set screws way down in there that hold the whole aluminum assembly on.

[seth_3515]

Hell yeah! I'll be doing that while the head is getting worked on. Thanks btw on the quick shipping with the springs, cam gear, head bolts and other odds and ends. You guys have been great!

Yeah we need a update

[seth_3515]

Well, my 3-row Valero radiator came in yesterday along with a 16" and 12" fan. I'm getting an IE fuel tank, talking with gonzo about possible tuning, and thinking about snatching some genesis II 1000cc injectors. This head Should be done in a few days as well. It has super tech Valvetrain, custom porting, new seats and IE cam gear. This pic is bare head pre assembly..

[seth_3515]

Guess I should explain the fans.. I am using the 16" fan as my puller. It fits the radiator and was rated at 19~~Cfms. I already have a small 10" pusher on the awic heat exchanger and will add the 12". These are all universal fans that will be wired to a switch in the cabin. I am contemplating hardwiring the puller as it won't hurt anything but longevity of the fan to keep it running (fewer switches) I would turn the pushers on only when needed/at idle in traffic

[JohnnyLlama]

Check your emails or inbox me your number buddy

[seth_3515]

Johnny- pm sent

The ups guy has got to love having me on his route..


This is the radiator and fans I received yesterday. I had a few people ask how I'm wiring them up..
I'm using a simple 30amp relay. The 16" can draw 10amps @ 12 volts so I'm wiring the fans all to the same relay. Just using an interrupter switch on each power to the fans (except the 16" it'll probably get hard wired and constant power)

[seth_3515]

Ok, I decided (and ordered) my IE surge tank and Genesis II 1000cc Injectors! They will be in my hands monday. I have talked to Gonzo and we are working together to bring this build together and happy ending. I am going to use a similar placement as One-Eight GTI for the surge tank. After looking around and trying to come up with a new idea, I couldnt find a spot that suited my setup better than his. I got plenty of new fuel line from Summit and hopefully get my head back soon. In all honesty, once I have the head back I have a full day of work to get everything back together and running. I plan to get with Gonzo at this time to give the ecu a new base flash for the injectors and drive around for awhile to adjust fuel trims. Luckily, Dunsworths has a dyno as well and I will use the dyno for final tweaking.

-MOTIVATION TO GET THIS DONE- I was conversing with my wife about the TT and how I would really like to get an AWD TT. We have been looking for a house and should have one purchased within a few months (if we can find something we like). After we have purchased the house, I was given the go ahead to find an AWD TT that I want for the swap. I have been Craigslistin' for awhile and have come across a good deal or two so I know they are around me. My wifes only stipulation is that the FWD has to be in good running condition before. That way its literally swap blocks and sell the FWD and keep the AWD. I think next spring is a good goal for a 500AWHP TT

[One-Eight GTI]

You have yourself a good wife there Seth. I lucked out with mine also. I've been spending a lot on my car over the years

If you need anymore pics of my surge tank let me know before next weekend as my bumper and core support will be going back on than
