If you are on the fence with the kit, you really cannot go wrong with it.

If you go for a twin turbo kit, expect to spend thousands more. Other kits out there do not come with a downpipe which costs 800+ alone. Then you will need an oil cooler kit too. The BP kit eliminates the downpipe and comes with a oil cooler. If you have someone else install it, it will take less time and cost far less to do the install than a twin turbo kit.

I mean, don't get me wrong, when you are going for big power you should not skimp out on cost. Even though you should not skimp out on it, it is still a factor when it comes to shopping for a kit. With the high quality of the BP kit, the price for it is quite cheap if you ask me.

Why do I always find myself in this thread?

Because your following me LOL an I'm following this too hahaha

I appreciate the info and original kit dyno sheet... Im not sure exactly how the air flow changes with the bump to a 1.15 (i understand that it does change and why it changes), but what does that change correlate to. Just more uptop power, more power across the board, slower spool time, more total power potential but the need for more psi to reach the same power lower in the band, etc?

500-550 is really my starting goal, which is perfect in this kit but would love to down the road build the engine a year or so later and push towards 650+ if possible. How much of a potential difference is there with the upgraded 67mm turbo. Thats the largest that fits the kit i recal reading somewhere correct?

I think that anything over 550 is not attainable with the current vvel setup we have if I'm not mistaken. More than 550 and the vvel computer will not be able to keep up....

Mr Squeeze is still running VVEL heads and he's well into the 600s if I'm not mistaken.

The 1.15 a/r turbine housing will reduce back pressure, allowing more fresh air in to the combustion chamber...translating in to more power. The spool up won't really change to be honest.

The 67mm turbo (which you can purchase with the kit for $200 extra) will get you well in to the 600's. I have customer with the 6266 on a VQ35DE in the mid 600's on pump gas. That is the smaller turbo, and smaller turbine. Supra guys have made over 800whp with the 6766 turbo, so it will make a lot of power.

The nice thing about this kit is that you can get the 67mm turbo upgrade for $200 now, go with the 1.15 a/r turbine housing and then when you build the engine it is only another $250 to upgrade the turbine housing...allowing you to max out the system.

Interesting... Ecutek or Uprev? I'll have to see his build.

I know more hp is possible, but I wasn't sure it was controllable...

Damn that makes for one tempting offer, and some great number potentials.... Fingers crossed for a nice bonus check in a month lol And that i can afford the neccessary guages to go with the kit. (i'll wait till i burn the stock clutch out to get a new one haha)

Sounds good, just let me know if you wish to proceed. I ship within two weeks of receiving the deposit...that alone is something hard to come by these days.

7AT 7AT 7AT!!

:bowrofl:

I had a good look at some pictures of a/t 370z's, and there is just no way this turbo would fit in that location. The oil pan is just way too big, and takes up a lot of the space needed for the turbo alone, not to mention the plumbing.

:crying:

If you build it, we will buy it... :p


And there is no other location you could possibly put it? I'm not trying to rearrange your whole kit, but I REALLY want your kit when the time comes and just wish there was some way you could make it work with the 7AT. :(

I know you guys would buy it.

The T4 frame turbo is large, much larger than what the competition offers in a ST kit, and this is the only place I can make it all fit. Here is a side by side picture of the turbine housing that I use with this single kit, and a T25 turbine, commonly used on the TT kits:

That is a picture of the 1.0 a/r turbine, the 1.15 a/r is larger than that, and the 1.32 a/r is even larger than the 1.15 a/r.


As you can see, there is a significant size difference, and I am very limited with the location. This is the proper size turbine for this engine when it comes to a single turbo, so anything smaller than that, and the kit max HP potential will only go down.
