Yes my buddy had the SAFC on his eclipse. They work very well for how inexpensive they are. One thing you may consider down the road, though you arent running much boost, is throwing like a 220 watermeth nozzle on that beast. I have a 550 on my audi and it makes ALOT of difference. After we built the manifold and got the 53mm turbo on there (stock was only 38mm) and going from 12psi to 20psi I was running in the 12.0-12.5 AFR range. Installed the meth and runs solid 11.5-11.7 AFR's, another 5 degrees of timing and way more crisp throttle response. Plus for me the 2.0t fsi direct injection allows the intake valves to carbon up so the watermeth keeps the internals looking shiny clean! Lower IAT's, more timing, cleaner internals, lower EGT's and drops AFR's 1 full point at full spray allowing more boost without fuel cut. Cant go wrong there $Beer Chug\'n$ I have the AEM kit but I've seen people build it for cheap on a budget! Cant beat boost, who doesnt love to listen to a turbo spool???

This is very useful information. I'm just doin what I can for now to even be boosted at all, I'm on a super small budget, actually I have no budget I have a baby on the way and shouldn't bf spending any money on my truck but the extra ponys I'm gettin is well worth it.

If I was going to buy a kit I would get the kit from KO racing its about 2400 Theresa ton of different options for turbos and other parts when you personalize your kit. Someday that's the kit I want bad. They are made to bolt on and run 4.5-5psi no aftermarket management.

Crunchy Taco · « **Reply #153 on:** Jul 28, 2014, 06:05:30 AM »

So I changed turbos again to get my boost down a bit lower the wastegate on the 12b wouldn't allow me any lower unless I took the optional cap out and make a dump pipe comin off of it. I'd have to take pictures to show you guys but anyway my latest turbo wastegate flows straight out. If you open it all the way u could damn near bypass the turbo all together. So I don't have a wastegate acuator for this turbo but there is one I wana get that has different springs for it from 5psi on up. For now I built and adjuster for the wg and I'm right at 3-5psi now 5 psi max wich is nice I can floor it all the time with no issues what so ever.

I miss the built in BOV the other turbo had so I actually found another turbo at a junkyard on a 91 volvo 740 that has a free flow wastegate housing on it and also has the built in atmospherical BOV plus no shaft play. So I think thats my next setup.

I have a video I just have put it on utube but for some reason I can't do it on my phone I'll have to try on the computer at home

Wish I could just buy an external waste gate setup.

T3 Flange: Ebay

and a nice TIG machine $Beer Chug\'n$

I have an exhaust flange for 20r/22r/e from LCE with the 1 5/8'' ports sitting on the shelf, tossing around the idea of boosting my runner but I just want to get it going before I tackle another major turbo swap. Plus the old ECU's are VERY limited with what you can do... I had to purchase an $800 interface for the Audi from Maestro to tune it. My turbo is a T3 borg warner GM3 off of a GMC 6.5 diesel I scored for $50 then rebuilt it for $90 and custom shaved the housings and custom drilled surge ports in the compressor side. Needless to say it whistles LOUD Guys want around $1200 for my style of manifold and we built it for less than $500.

Now enough of the high jacking.

TacomaLover, how are you with a TIG welder?

I haven't done much tig but I've been stick and mig welding for ten years. If I got a tig I would use it and use it well. You can high jack this thread all you want. the stuff your doin is what I wana work up to. Bigger turbos, better headers, stainless steel, all that goodness. Right now I'm messin with tiny turbos and crappy parts but it's still fun. I wish me electronics would show up it's been almost two weeks. I probly don't need them till I get some better stuff anyway. I'd kinda be afraid to run any high boost on the crap I got right now.

twistedtoy92 · « **Reply #158 on:** Jul 29, 2014, 06:47:54 PM »

Hey any time man! I'm glad to see people out there actually DOING mods like this instead of just talking about it. So hats off to you my friend.
If you have been welding that long you'd pic right up on TIG. Steel is fun and fairly easy but aluminum is a bit harder at least for me. Check out ebay for cheap external wastegates, I have the Godspeed 50mm wastgate on the Audi and for as cheap as it was its working well. My buddy has the same one on his 4g63 and its putting down close to 700 AWHP... Not bad for an ebay product... Tial would be sweet but a bit pricey.
Congrats on the baby on the way, kids are a lot of fun, but a lot of work... Worth every minute though $Beer Chug\'n$

How many turbos do you have now? LOL!

Crunchy Taco · « **Reply #159 on:** Jul 30, 2014, 06:07:26 AM »

Thanks for the reply. Yea I've been looking at the wastegates on eBay prob what ill do eventually. S--t I got like 4 turbos 3 of wich I'd actually run and after today I'll have 5 cause I'm goin to get that one at the junkyard it's in really good shape. One reason why I wana go back to the same built in atmospherical BOV like the turbo I just took off had is cause it was awsome at regulating pressure and now for some reason with my eBay BOV and a Saab recirc I tried I have the problem of the motor dying sometimes comin back down to an idle. Everyone talks about Tacomas doin this when runnin low boost on stock ecu. Mine never did thîs til I ran a turbo wirhout a built in recirc or BOV.
Here's a crappy video hopefully this link works

Video works! Sounds good!

twistedtoy92 · « **Reply #161 on:** Jul 30, 2014, 06:57:11 AM »

Sounds good man! Yeah I can understand why it runs better recirculating the bov with the stock ecu settings. It also helps keep the turbo spooled up between shifts by utilizing that compressed air to help the turbo out rather than wasting the energy into the atmosphere. Just got done installing the biggest injectors you can get for the 2.0t fsi that are out of the RS4 and R8 Audi. Retuned it, redid my MAP sensor mount and went from one 550 w/m nozzle to two 315 nozzles. I gained way more top end, spools at 4100 rpm and holds 14 psi (turned the boost down) all the way to 7800 rpm when it was dropping boost around 5800 rpm before and hitting rev limiter at 6800 rpm. The Bosch Me7 ecu's are incredibly too smart for their own good sometimes... and a pain in the ass to tune.

Which turbo do you prefer the most out of the ones youve ran?

Crunchy Taco · « **Reply #162 on:** Jul 30, 2014, 07:21:50 AM »

Sweet thanks. I'll try to make another one that's better

Crunchy Taco · « **Reply #163 on:** Jul 30, 2014, 07:25:56 AM »

My favorite so far is the volvo td05-12b with the atmosphere BOV built in. I'm getting another one today with a different style exhaust side for better flow out of the wastegate. These turbos are all too small and create alit of heat so eventually wana run something bigger but for now these are ok to play with!

Crunchy Taco · « **Reply #164 on:** Jul 30, 2014, 07:27:03 AM »

Strong work on the Audi son! You really kno your stuff. Good guy to have on my side building turbo setups

twistedtoy92 · « **Reply #165 on:** Jul 30, 2014, 09:18:13 AM »

Thanks buddy! I just got into the turbo scene alittle over 2 years ago after I rode in my buddy's 95 gsx with a Holset hx40... thing just ripped! I was instantly in need of a turboed vehicle. I went out many late nights tuning DSM link with my buddy "The Mad Scientist" and caught on fast. Our whole thing is building everything on a budget yet still have outstanding reliability. He was building houses but I got him convinced to go to work for a speed shop in town and he is building some awesome stuff! I have to give him most of the credit for the welding as we built it in his garage and he insisted that my car was a guest so he would be doing the manifold and intake piping. I hate buying bolt on kits.. For instance, they sell a K04 kit for my car that has a price tag of just under $7000.... and you net around 250-275 awhp... plus it looks stock. We built everything from the intake pipe all the way to the mufflers for around $1500 and I believe I am putting out around 320-350 awhp on less than 20 psi. Still working out some tuning issues but I'll hit the mustang dyno again soon.. I put down 181hp and 250tq with stock turbo on 19psi. Hopefully almost doubled it. Its a lot more unique and rewarding when people ask you, "Where did you buy that or who built it?'' Well we did! So keep at it and you'll only gain more knowledge and experience $Beer Chug\'n$

Thats what I would have guessed. You should measure the inducer and exducer on both compressor and turbine side wheels. Also, whats the A/R differences on the different housings? I'm curious to see the differences. I'm also thinking about a 14g or 16g turbo on my 4runner but thats still in the air... My stock snail was so damn small, running it hard would make the whole manifold/turbine housing glow orange.... way too much drive pressure but it would hit full boost by 2200 rpm. It was a fun turbo in the tight twisties but straight-aways boost would fall off dramatically after 4800 rpm. Larger exhaust housing will definitely benefit you to reduce drive pressure/ heat in your head. Gotta be more careful "over boosting" an NA engine as opposed to one built with turbo worthy internals. Thats why I can run 25 psi with 10.5:1 compression and still get away with it on a fully stock engine with 140,000+ miles

Crunchy Taco · « **Reply #167 on:** Jul 30, 2014, 11:19:19 AM »

I'm not sure about the exhaust housing but the compressor housing is .48 on the Garrett. it glows red if I'm on the boost a lot. Not as much now that I'm runnin lower boost but it will still get the exhaust housing red. I really need to learn what all the numbers mean. Are you in Oregon? That's where I live. Portland and prineville

Yeah there are some good books out there! I have a good one I'll post up the name of it when I get home from the shop. I have some stuff from the EFI 101 tuning course I took at Kiazen Speed up here in Kennewick WA. which focused mainly on calculating all the VE/timing tables and waitnot to setup baseline on standalone managment, then the fine tuning on the dyno. It was a good course, Bryan Macie put it on and that guy tunes all day everyday! Check out some youtube videos on him, he had a 2000hp chevy monster that he was tearing down and shooting for 4000+ hp... CRAZY power.

I called to order the KO kit originally.. They said it was 10 weeks before they started to make the manifold/down pipe. Lame.

Crunchy Taco · « **Reply #172 on:** Jul 31, 2014, 04:56:35 AM »

Yea that's the only thing is the wait time on the KO kit. The funny thing is they're right down the road from me in in Oregon city Oregon so I read on the net I haven't been over there yet

Crunchy Taco · « **Reply #173 on:** Jul 31, 2014, 06:26:36 AM »

I like building my own stuff but I would love more than anything to get a kit from KO racing it would be well worth the wait. The owner really talks his exhaust manifolds up pretty much guaranteeing them never to crack and if thèy do send it back and he will fix it. Lifetime warranty. For a tube style manifold they are a reasonable price as well if I don't build another mani out of stainless like I want to ill order one from KO. I've also been looking at manifolds for Hondas and there's a huge selection. For 150 coin I can buy a honda mani then I was guna try and flip it and weld a Tacoma flange on it probly having to add little pieces to line the tubes up on the flange. I've really been thinkin about a lot if affordable ways to have a decent 3rz turbo exhaust manifold. I also really like the idea of running a dump pipe off an external wastegate right out a hole cut in my fender. Ha ha that would be sick. Anyway IMO putting together your own kit is way way way cheaper than buying someone's kit and like twisted toy said, you can say you built it, and be proud every time you look at it.

Nation · « **Reply #174 on:** Jul 31, 2014, 07:04:11 AM »

Yeah it'd be way cool to make my own kit. I Just Can't Worry About My welds... KO racing would also build the down pipe custom for my swap.. sweet. Only thing lc really has going for it is its readily available and the kit looks somewhat factory... i live in ca where they really do care what you have under the hood.. in a perfect world I'd get the km kit but there's no way I'm gonna fork up 2450 and wait 10 plus weeks.. he told me 10 so figure on 13 lol.. if and when the lc mani cracks I'll order up a header from KO and wait the 10 plus weeks.

Crunchy Taco · « **Reply #175 on:** Jul 31, 2014, 12:17:56 PM »

I here yea. Lc manifold is supposed to keep heat down for dd as well.

Nation u guys in Cali arnt alone with vehicle emîssion compliance u have to pass here in Oregon as well. I don't think we have quite as many emissions on our vehicles but still if I wana pass smog I would have to take the turbo off. I have my truck registered at my old address wich was up in the woods pass the smog boundary that's one of the big readons I ever considered the turbo right now cause my tags expire next month. But yea seems like Cali is the worst.

California and new york.. the worst. I got my truck smogged last month

That's awsome. U have to have a cat in most parts of Oregon. When I do have to smog I just put it back in for the test. My truck is a turd with the cat in.
