Unfortunately, I am not local to you and lives in Petawawa,Ontario (military base). I swapped the 6MT in the Z instead of the 7AT when I did the HR heads swap.

>>>>>Puckshaw's Boosted Performance Twin Scroll Single Turbo Build<<<<<
 

I think I got the exhaust leak sorted with the RTV. Had a nasty rattle that I fixed. Now all that's left is a very subtle rattle that I can barely hear at certain times. Can't replicate it while under the car. Doesn't bother me really but I want to track it down eventually.

Put some miles on the car today. Using dash command to get the boost reading and I don't think it's calculating it accurately. It's saying 12 psi without even hitting full throttle. Either way I'm playing it safe until I get the tune on Friday to see how much boost the car is actually making.

Here's a quick vid of a partial throttle pull. I'll do some proper videos after the tune ;) LOVING the car so far!!!

I tried DashCommand to read boost also...got crazy numbers :P Don't know why it isn't accurate. Kit sounds good man. Almost makes me want to get my open-pipe external wastegates plumbed into the exhaust. Mine is so loud I can't hear the turbo lol.

Are you using a boost controller? You won't hit 12 psi if your only using the wastegate springs.

I think it sounds perfect with the recirculating waste gates. Perfect blend of turbo, exhaust, BOV noises :)

Just running waste gate spring pressure. Should be the 7.25 psi springs but I'm just being cautious until I get the tune. Not going to kill me to wait until Friday ;)

Yeah, you're good to go. Last I heard the base tune was based off of my car when I had Vince at R/T Tuning tune my car. Always a good idea to have it looked at jut to be sure though. :tup:

I liked that ****!

Sounds great bro! Can't wait till your tune!

Sound is pure sex, this kit sounds wayyyy too beautiful recirculated to even think about dumping it. Great job on install, so clean and easy!

Nothing but smiles from the BP pack it seems!

Congrats on the DIY install. It seems that all the customers that have installed the kit themselves are happy, and did not find the install to be all that difficult. Money saved, and more importantly, you know the kit very well if you install it yourself. This IMO is very important.

It puts a smile on my face when I see customers install these kit on their own....it assures me that I as a manufacturer made the kit simple enough to make this possible.

The car sounds great in the video as well. IMO the combination of the twin scroll kit and the F.I exhaust system is a perfect match. Not too quiet, not too loud, but the other drivers will know something is going on under the hood.

Best companies out there all tied into one!

Yeah I'm sure it's fine but just being safe since the tune is only a few days away. It's really hard not to go full throttle though :D Can't wait to give it the beans and see what it can really do.

Thanks guys! I totally agree on the sound. Not obnoxiously loud but not quiet by any means. Really nice exhaust note and intoxicating turbo noises lol. It seems like the VQ off throttle hiss is gone too. That always annoyed me. So far I couldn't be happier.

The install really isn't that bad at all. I did it completely alone on jack stands in my garage. The only snag was me not pushing that fuel rail harness a millimeter farther to lock in. Just a simple mistake on my part. Like Sasha said, now I know every bit of this kit which will be great for maintaining the car down the road. Great product from BP and even better customer service :tup:

good choice switching to the BP kit, car will be running before you even get a refund from GTM :shakes head:

His car is already running. LOL

:rofl2: I got the car finished over the weekend and my bank is dealing with GTM now ;)

The car sounds awesome man! Ill also be joining you in a few months my friend.

You'll be giggling every time you go WOT for weeks. The first time you hammer it after the tune, the car will scare you.

Thanks! Looking forward to your build :tup:

LOL I'm already giggling at part throttle. I can't imagine how it's going to feel at full throttle. No doubt it's going to be terrifying :eek:

My whole drive home from the tuner I was thinking "Are you kidding me?". :rofl2:

I must have missed an entire page my bad lol

YES!!! ^^^ THIS!!! :tup: :tup: :tup: :tup:


:inoutroflpuke:

Got underneath the car last night to try and get the exhaust to line up better. It seemed like I still had a small leak at the rear v-bands. I loosened everything up and discovered by pushing the y-pipe as far to the passenger side as it would go, things lined up much better. The thing that threw me off at first is at first glance it looks way off, but the flex sections allow it to bend into position pretty much perfectly. Without doing this, I wasn't able to get the faces lined up flush. It was a little tricky getting things tightened up while trying to keep everything in position since I was having to pull things in different directions but I managed. Took it for a spin this morning and believe that did the trick.

I also found a couple very small oil leaks and snugged up those connections. I'll check again tonight to make sure they're fixed. I do still have something that rattles a tiny bit when I go over moderate bumps. I'm sure it's an oil line or something like that. Probably going to be hard to track down since I can't really simulate it while under the car.

Two more days until I get her tuned :tup:

Yea that's part of the game. Exhaust components can be tricky. With time they will settle more. Just keep checking things weekly.

Yeah the flex sections have already loosened up a bit as Sasha said they would and were easier to work with this time around. I'm really glad I did the install myself so I can make all these little adjustments on my own. I wouldn't even have noticed the oil leaks if I hadn't gone looking for them. It wasn't enough to even drip on the ground. It was just building up some residue around the leaks.

I have always been an advocate for DIY if you have the means to do so for that reason. You never know when you will have minor hiccups, and its best to know your way around your car so you can resolve any issues yourself, rather than have to take it somewhere and pay money.

How was the electrical during the install? Im pretty well rounded mechanically, but im retarded when it comes to electrical.

:iagree:

Something like this I'd DIY in a heartbeat. It looks like a fun project. I farmed out my TT kit because I had no desire to drop the motor and tap the head and oil pan. Good job on this one making it DIY friendly. That's a substantial cost savings there.

This is spot on, and the driving force behind all the kits that I have available. A lot of time is spent making things as simple as possible for the installer.


The electrical is very easy, but those that did the install can chime in.

The scavenge pump harness is plug'n play. Positive terminal to BAT +, negative terminal to BAT -, for the pump there is a water tight connector/plug, and then you just plug in your relay on/off source in your fuse box. All the fuses are already in the harness when the customer receives it.

The fuel injectors are also plug'n play

The fuel pump..there is two wires that need to be soldered, but it is very easy. The instructions go in to good details with this.

Too many manufacturers in aftermarket car parts seen to forget that it's guys in their garage drinking beer installing their parts, not trained mechanics. It's good to see parts designed around the "average car guy".

Agreed.

Electrical is a non issue. Very simple. Honestly the hardest part of this kit is,

1. Removing the factory cats (demon bolts)
2. Getting the turbo to fit into the coupling going to the inter cooler piping.

Yup as everyone said, the electrical pieces are very easy even without any wiring experience. For the most part, I really enjoyed myself while doing this install. I agree that the hardest part was getting the turbo connected to the intercooler piping. Next hardest piece was probably separating the oil pan for me.

Great build man! Hopefully soon I will be in your shoes also with my own BP kit :)

Do you have the recirculated or open westgates? Whats your opinion about it?

Could you advise please which boost controller should I choose?

I would go with the EVC6. If you decide to not get a boost gauge, that controller can act as a boost gauge. 2 in 1, can't go wrong.

As to recirc or not, if you want to hear your turbo and BOV then recirc. The turbo and BOV will not be as loud with the open dumps screaming.

You are right outside Chicago too. If I have time, I may go to the Cars and Coffee meet during the spring. If I do go, you are more than welcome to come and check out my BP kit. I am sure many others are interested in seeing the BP kit too.

Thanks! Great choice on going with this kit! I have the recirc waste gates and absolutely love the way it sounds. Open dumps can get pretty loud but only open up when you're making full boost. If it's a daily driver, I'd go recirc. Hell mine isn't a daily driver and I still went recirc. Sasha can sell you the dump tubes also if you want to switch back and forth. Not too expensive.

I'm not running a boost controller yet but plan on getting one eventually. I'm leaning towards the g-force II. looking forward to your build!

This isn't apples to apples but when I had a turbo'd spec v sentra, I had open and recirculated wastegates throughout my journey. Started first with recirculated. The turbo sound was pretty crisp at full boost. You could hear the turbo and exhaust pretty well. Each were defined fairly well. I eventually swapped to an open dump due to a design flaw that caused my manifold to wastegate gasket to blow. No flex coupler and the pipes would heat and expand at different times bla bla bla. The open dump was loud. It was fun to hit boost next to someone with an open window lol. The only thing is it sounded kind of dirty. I'm not sure how to explain that but that's the best description lol.

Personally I would (and am) going with recirculated. Sounds good.

If you don't have a boost controller, I would suggest going with a larger springs (than 7.25psi you have) in the wastegates now.

I would put the red and green spring in, yielding about 10psi

(chart, right hand side: http://www.tialmedia.com/documents/MVSspc.png).

The boost will taper off to about 8psi by redline due to the VVEL, and the tuner can esily adjust timing to make the torque nice and gradual as the boost comes on. The tune will still be very safe, and you should get over the 500whp mark with ease.

Open dumps are awesome. For about a week. Unless it's a track toy, recirculate.

If you don't plan on having different boost settings, a good manual boost controller can handle a lot of what you're looking for. You don't get a lot of cool stuff, but they almost never fail and they're very cheap for quality units.

Very true. I am alos looking at having a manual boost controller go out with the kit. It is simple, and does the job. Probably only a $120 option.

I'm using a TurboXS manual unit, and I'm perfectly happy. Cost me $99 and works like a charm.
