Boosted Performance or Custom Turbo Build

Neil912

Hey guys, so I just wanted some input from all those that have gone the single Turbo route. I know Boosted Performance has a great looking DIY kit that I would definitely do myself...no installer fee! WOOT! It has a very good price for the high quality parts and work put into it. It also posts very good numbers for stock engines. To complement Boosted Performance I would purchase the F.I. Exhaust and I would get the Z1 clutch with the ZSpeed HD CSC and Master replacement. I am not sure if I will also get the flywheel or stay stock. For the BP kit I am paying tuning fees unless I jack everything to hell. The exhaust and clutch got quoted for $440 by Knoxville Performance and Dyno Tuning Center. All in all that is not too shabby in price for everything. For those that haven't upgraded the OEM MAFs, have you had any issues with A/F reading? Can the stock support 480 to 550 whp decently?

Now for the custom turbo idea. Through the same place Knoxville Performance, I was quoted $10,000 for a top mounted single. This would include the labor fees for the clutch and exhaust. They told me to hold off on an exhaust until they know what will work best with their turbo idea. They plan to use either Turbonetics or Garrett turbos and not sure which model exactly. Their quoted price would not include my costs for the exhaust and clutch, that would be extra. I would be looking at around $13,000 or $14,000 when all said and done with extras, new tires, etc.

I am still working in Afghanistan so none of this will come to fruition anytime soon. Would you guys take a blind leap of faith and go with a custom build from somewhere you don't exactly know if the results will come out the way you wanted? BP already has enough product review I should probably go with that, but going the custom route seems exciting as well.

Just buy the BP kit, it is not worth the hassle of having a shop do a custom build with unknown results. If you consider the custom route look at their history, have they done VQ single turbo builds, tuning experience, and level of confidence in doing it (do they seem iffy when they talk about it).

I have no AFR reading issues. I bounce around 14.7 closed loop and low 11's WOT. My MAFs are maxed out but that shouldn't be a problem for anyone buying a BP kit now as they now come with 3" intake tubes and my version is 2.75". I maxed the MAF at 503whp but some are running slightly more than that. The upgraded 3" intake tubes should eliminate MAF issues on a stock block. Now if you are building a block I would budget for the UpRev MAFs.

Z1's clutch setup is great, I have no issues with it but I would recommend the 6 puck. FI exhaust all the way!

Join the BP club bro, it's well worth it!!!

That is my number one problem with even considering doing a custom option. I personally don't think they have that much experience with a VQ, but their technical experience might be good enough to pull it off fine. Right now I am definitely sided more towards the BP kit. Proven and a great price.

Neil912

Okay that is good to see about your MAF readout. I personally don't want to buy Uprev MAF GT when I can see 500 whp at least with the OEM. I am not going to be building a block or anything like that. I will try to keep the engine internals stock. About the Z1 clutch I would have to do more research into the 6 puck vs regular sprung option and how it would affect daily driver ability.

I was actually upset when the dude was like don't buy an exhaust and in my mind I was like awww hell naw! The FI with 18 inch resonators will be mine!

Also, you gotta give major props to Sasha for his kit and creating a product for us awesome Z people and uhhh *cough* *cough* Infiniti bandits. All that piping around the transmission though...I can get over it.

jwick

You can reach 500whp no problem without upgrading MAF

Go with non-res exhaust the turbo is a hell of a muffler

I would love a video to hear what that would sound like. I will try to find one on google.


Boom! As always google never fails. Went right to the part of Sasha's thread about the FI Non Resonated.

If your looking for turn-key I would also suggest vsr out of tampa. Top mount turbo kit, been out longer than most other kits and proven as well..

Neil912

If I remember correctly is that where I would have to send my car to them? I will look around and see if I can find a price for their total fees. I am not keen on shipping out my car, but it would be a nice present for my return home to have a completed car when I get back. I could always have a family member do it for me. Especially since they already like taking my car for a spin without my permission

jwick

That's the major draw back to me on the VSR kit that they ONLY do in house installs.

BP kit is nice due to the fact that it is very user friendly installation wide. It's really good complete kit. It includes a good size oil cooler which to my knowledge no other kit includes. The only thing that has me a little worried is the location of the turbo itself. Of course I will try my best to avoid puddles, bumps and all that but sometimes it can't be helped. I really don't think it would be cool to "dip" the snail in rain water. The other big thing is that Shasha is at the end of this rounds v2 build. Nobody knows when he will build the next set so you might be waiting for a little while for one of his kits.

If your going to be dropping the long block, you really don't have any limitations on turbo kits. You can pick whatever one you want or like form the many kits currently available. If I were to go TT, pay someone and install the kit, I would either go FI or AAM. FI is just bad azz and darn good product. They are upfront and tell you what is happening and is going to happen (such they take deposit then you sit and wait for 2 months for CBX). There will be no "what if." IF you do have any, all you have to do is call them. The thing about the AAM kit that I like is that they keep the factory crash bar. IDK but I like that.

I myself went BP because I like to DIY. I really love the simplicity and and effectiveness of Shasha's kit. Plus it's more affordable to me with is a big plus.

BP is is hands down the best turbo kit for the street user that can self install. PERIOD. If I ever got back into a Z I would immediately buy another BP kit for the car, you will not spend a better 7k and get a more complete or quality collection of parts and materials.

No res FI exhaust on the dyno BP kit...I miss that car



this is on low boost before a full vince tune, but gets you a good idea of the sound...AHHHH that BOV.

Thanks everyone for the input so far! This board really does have some awesome people! I like the BP kit due to being the cheapest kit and easiest to do. Now my issue is with the mounting of the turbo and thats basically it. In Tennessee we experience a lot of rain and when it rains it pours. I will daily drive my car and I am afraid of what all that water is going to do to the turbo. Has anyone personally developed a custom shield for it that I may be able to replicate? I know that having the turbo underneathe helps with everything being cooler as well. I don't want to block air flow or cause too much heat.

I am looking at VSR as well and will contact them in a couple days after reading input and doing my own research. Because I am in Afghanistan I would need help with arranging the transport if I went this route and going over my total cost since they would need to also install the exhaust and clutch. I know it will be much higher than going BP, but should be less costly than the TT kits. The TT kits at this point are eliminated unless I decide to stay out here longer. I already did 15 months, took a 3 month break, and now 3 months again looking to be 7 or 8 months. Not sure I want to miss going back to school just to TT my car lol. Although, that would be one bad *** Z!

One thing I am curious about is the RPM at which the turbo begins to spool on both BP and VSR. I know that has to due mainly with the turbo housing and the size of the airflow amount...something like that.

jwick

Don't worry about water. The turbo filter is tucked up nicely above the subframe. In fact I think it sits higher than one of the filters on the GTM TT kit in the nose of the bumper. If you go thru enough moving water to submerge the filter it's going to be enough water to carry your Z away and at that point you will have a lot bigger problems.

In my opinion the turbo in the BP kit is a better turbo than the one in the VSR lit because it's a twin scroll. My boost threshold is 2300-2400 rpms with full boost 3200-3300. The twin scroll damn near acts like a TT setup. Turbo lag is a couple hundred rpms.

Edit - I've driven thru some pretty heavy rain here in Houston and never had an issue

Thanks for the reply back on that! I really wanted that input on the water. The biggest problem in TN is the heavy downpours and the occasional hits in the puddles on the roads. Since that won't affect it then its and in the end it always comes down to pricing and what I feel comfortable spending. I could use the cash spent on another place for gauges, tires, and other stuffs. I'll try to see if Sasha could possibly have a 2.0 kit available by June/July time frame.
