Time for new exhaust

Time for the 2.5" exhaust to be replaced. I believe its causing the power to drop off in the higher rpms. Also still cant get ride of these damn exhaust leaks at the downpipe. So I have decided to replace everything.
Enjoy.

Sexiness. Now I really want to work on mine right now.

Looks like you won't have a problem with wastegate that I did.

Everything looks nice, though I still don't trust the manifold. What wastegate is that mani designed for and which one do you have? Mine is a TiAL 38mm and it has the round 2-bolt flange.

Also, I'm no expert on turbos. What was the reasoning of switching exhaust wheels and housings? Better spool? Or better top end flow im guessing?

What brand is the exhaust and manifold? XS Power?

I wasnt aware that they made v-band adapters like that, thats cool. When do you expect to have everything installed?

P.S.,
Dave: your a dick

Manifold is obx and designed for a 40mm wastegate. Thats the 4 bolt flange, I will be using a 38mm so Im going to cut that entire piece off and weld it facing the other way and also changing the flange to a 38mm. The T3 exhaust housing is bigger and will flow much better, also the td06 wheel is much bigger and will flow a lot better in high rpms. The td05 wheel becomes a restriction once boosting 20+ psi. With new injectors I plan on pushing this turbo to about 28psi so the smaller wheel had to go.

Planning on having it installed in the next few weeks. Over thanksgiving holidays at the lastest.

that looks great. Can you snap another picture of that muffler though?

Sure which part do you want to see?

That looks hot!! How soon will you have it all installed? Any pics of the car as it sits?

Hopefully next weekend I will have it on. Ned Ill snap some new pics. The eclipse needs to be washed first, its pretty dirty

You think yours is bad... should see how much dust mine has on it from being the garage for so long. Can't see out the front window... except for where I tagged it ;)

like looking down the tail pipe. t looks like the hole gets wicked small.

That's the silencer. They pop out.

What exhaust do you run steve?

Weld some bracing under the ports on the mani!

You cant really see them but there is extra support welded to the top of the runners

its a custom exhaust. Really Really well done only cost me 400 bucks with all mandrel bent galvanized aluminum piping. full 3 inch. :)

So if all goes well the exhaust is being put on Sunday. My roomate has found us a lift that we can use for the day along with a welder. Today I went ahead and cut one of the flanges off the catback, where is necks down to 2.5". This is getting replaced with a vband. I also appempted to remove the studs out of the T3 housing so I couls clean up the surfaces. Well of course I have bad luck and broke off one of the studs in the housing. Without having a torch here there is no way I can get this out. I went ahead and drilled a hole threw the stud and taped it with a 1/4" bolt as a temp fix. This will atleast hold the exhaust out and wont leak till I get this fixed.

The T3 housing will not even bolt up to the manifold bc it hits the wastegate pipe, I was thinking about working around it like Dave did but that is no longer an option. It must get cut off and welded back on another direction. This mani was designed for the turbo to face the passenger side like the 4g63 but I dont want to run mine like that so thats why I am having the problem with cleaence. Maybe workin on the manifold tmrw, I really dont want to cut up such a nice manifold but I guess I dont have a choice.

Well if you screw it up, another one is only what like $75-$100?

Another what? The manifold? Those things are $400 new.

So is the compressor is hitting the WG pipe? How bad was it? Mine is at a 45* angle coming off the flange. I don't understand why it was made to face to the passengerside... doesn't make sense. The PS and AC are right there, there's no space for piping or a filter.

Yea I'm not buyin a new one. I got this one for ab half price still in the box.

Dave the exhaust housing is hitting the pipe for the wastegate. And then the flange hits the center section.

wow, had no idea they were that high

I can't remember if my exhaust side was hitting it. Honestly don't even know if I checked lol. I had to rotate the center section a little bit so the oil feed could go in. Sometimes wonder if this thing is going to be worth it in the end.

wow, had no idea they were that high

Ya they're not cheap. Got mine for cheaper as well.

All hobbies are expensive, ours just depreciates a lot faster...I guess I can add a "lol" somewhere in here..:runaround:

Oh. Not talkin shit or anything, I just didnt realize that any part with an OBX tag on it, could go for more than $100.

Lol Ned

I personally think OBX is little under rated on some of there products. They actually have a HUGE product line for starting off as an "ebay company." My adjustable cam gears are OBX and have not had a single problem with them ever. I've read about people having the bolts fall out on them. That'll happen if you don't tighten them and check them. Here's little bolts on a part that's constantly rotating... you have to check that shit. Even with the Greddys and other brands, still ideal to check them.

And don't forget, the fact that there's a tubular turbo manifold for the 420a raises the cost up significantly.

My original CAI was an OBX and I believe my strut bars are too. All that fit perfectly too.

Yea Im not really sure why that manifold is so expensive. I guess because there is only 2 companies out there that make 420a manifolds that arent log style. The quality of the manifold seems to be very good, I feel like they could have made the fitment better but theres nothin we can do about it now.

Same time post!

A lot of responses in such a short period of time!!!1!

Well guys I just finished installing the new exhaust. Let just say that it was a lot more work than I anticipated. First off we fitted the catback on, it actually fit pretty good. About half of the hangers fit ok but the other 2 had to be rewelded. But thats no big deal. Then started on the manifold, I knew it needed a little bit of work to make it fit but this has to be the shittiest manifold I have even seen. It clearly was not designed for a 420a eclipse. Nor could they ever have even tried to bolt it up to a dsm bc the fit sucks on this. First one of the runners hit the tstat housing bolt. No big deal, I put a small dent right there and got it on fine. Turbo fit fine, a little close to the radiator but nothing to bad. The exhaust was pointed right into the AC lines. Got the a propane torch out and bent those out the way. I think I got one to hot bc it started leaking fluid a little. It stopped when it colded down so idk. The ac doesn't work anyways. Then for the worst news. The manifold stuck up so high that the hood would shut. There was ab a 3" gap. FML. So we cut out the hood bracing a little to get more clearence. That helped a lot but still didn't have enough. So there was pretty much only one thing we could do. Beat the shit out of the manifold till the hood will close. I wanted to cry everytime the hammer hit the shiny stainless. But we did what we had to and that all we could do. Im just going to wrap it in some exhaust wrap it wont look to bad. We still have less than 1/4" of clearence. You can flex the hood down and hear it hit the manifold. It should still be fine with some wrap on it tho. The exhaust turned out great other than that. For some reason the muffler is cocked at a stupid angle, its a little down so Im gonna fix that maybe over thanksgiving. Here are some pics.

Told you it sucks. Shit I wish I had a lift to do that shit with. The DP turned out really well. Much better than mine. Glad I don't have the AC... looks like a really tight fit with that in there.

Where's the WG dumping at now?

Yea it was nice. My roomate set that up for us. I can't imagine have to do that layin on the ground. It would have never turned out that good. Yea I would never have bought this mani if I knew I had to do all this. It still doesn't look to bad tho. Still got a leak on the vband goin to the catback. Not sure how to fix that. Dave have fun beating the shit out of yours. I'm very surprised we didn't crack a weld on it. I just threw the wg pipe on it from before but I plan on making a new one.

Now for some results. The car spools ab 2-300rpms slower with that bigger wheel and t3 housing. But it pulls hard on topend. Its goin on the dyno to get tuned on tuesday so we will see if we gained any power

So the WG is now coming out the front of the manifold? Pics of that?

Oh, how was spacing and fitting the IC piping with the exhaust and turbo being all cramped?

Its actually not to bad, the intercooler pipe is almost touching the DP but I put some heat wrap on that part so it should be ok. I made a sweet heat shield for the hood out of tinfoil this morning to protect the hood till I get something permanent on it. Also wrapped the radiator hose in tinfoil. Ill get some more pics today Dave. The wastegate didn't work out like I wanted to but I got it to work fine.

:sly: :sarcasmsign:

....Are you cooking with Betty Crocker?


Still got a leak on the vband goin to the catback. Not sure how to fix that.

Just clamp a beer can around it. :2cents:

I cant put a beer can around it, its the vband in the pics that is leaking. I took the DP loose today and even sprayed the flanges with copper gasket spray and they are still leaking. And its throwing off my wideband really bad. I did a few pulls today to check the tune with the new exhaust. According to the logs this turbo is spooling much slower than before. Full boost around 4600rpms but when it hits.. it hits HARD. It pulls a good bit harder than before and its making much more power up top. You could feel like die out around 6k or so but I dont think thats the case anymore. Tmrw we shall see on the dyno.

Im sorry man, Im usually not the negative person.......but that manifold looks like straight up ass hole. If I was putting it on my car and it fit that bad.....I would have taken it off and sent it back. I would surely have to run the old log style before that one. Glad the car runs better though!

I would have taken it off but I dont have anything else to drive. Manifold had to go on. It really doesn't look that bad. Got some more bad news tho. Was driving the car tonight and the turbo would spool but once it hit high boost, the boost would just drop back to 0 like a boost leak. Though a IC pipe was blowing off, came to find out it was the compressor wheel slipping. The compressor nut came off and hit the wheel a few times before finding its way back to the filter. The wheel is pretty damaged, I think Im still gonna run it for now and see how it does, if it starts getting a lot of shaft play the 16g is going back on till this one gets fixed. :(

Wow, no luck man...

Yea I know man, I cant win for losing. I put locktight on it so idk why it backed off. I guess it really isin't that bad just has 3 chipped fins. The exhaust wheel did make contact with the housing but it does not appear to be damaged.

yea, Ive never taken loose the nuts holding the wheels on....I've always been to scared that they would loosen up while driving.

I put locktight on it so I dont know why it came loose. Put the car on the dyno today. Results were not as expected. Boost was set to 22psi but was only hitting 19 for some reason. Also only put down 245whp which obviously is not correct. Turns out the tach signal was jumping all over the place which was causing it to be inaccurate. Didn't figure this out till the car was off the dyno so I didn't feel like strapping it back down today. Going to try and get some more pulls on Friday so hopefully will have better results.

Well I did get the car back on the dyno on Friday afternoon. It took a few runs before we got the tach signal clean and consistent. After letting the motor cool for a bit we did a pull on 11psi and put down around 210whp and 200wtq I think. Turned the boost up to 21psi and only got 270whp, turn it up to 22psi and put down 275whp. The car is pulling hard on the street so its putting out way more than this. Im pretty sure the dyno is getting maxed out. Its rated for 450hp but when I was talking to the dyno people he said that because of our calibration it would only read ~300tq. I guess Ill have to call them back and try to straighten this out. Got some videos that Ill try to edit a little bit and put up over the holidays
