That's the beautiful of having a boost controller for me I'm use to my power level so I would like spring pressure to be 650whp-700whp then go from there.

Boost controller or not with 1000 hp.. ok

It can be done my friend I have seen it not on this platform yet though.

I thought that the engine was limited to under 600whp because of timing issues with the vvel. In order to bypass this limitation people were talking about head swapping with a vhr engine. I truly thought we couldn't keep going up in hp until vvel was cracked! Am I wrong?

Yep. The fast intentions guys are pretty much all over 600. One over 650.

Underground Racing Lambos are running 1500hp+ on the street all day. ;)

Yes you are, look at the number in my sig been running this way for 2 years now built motor.

Those Lambos are just retarded fast I have had the pleasure of seeing some in person.

I just watched some data logs from my AEM gauge, the base map is quite good IMO for a base map on this kit, definitely a bit rich but around 10.3-10.5 consistently at 6-7 psi, this is getting too fun...upset I did not tap the RPM wire now, I think I will do that tomorrow.

Your car is pig rich once you take it to Vince he will set you straight.

Yup cannot wait!

How is the tune though, other than being on the rich side? Gonna be a month or so after install before i'm able to go get tuned, just curious how well it runs and everything on the base tune.

we can do our tunes same day, where do you plan on going? im starting my install Thursday

Honestly it drives really well, off of boost you would never know it has a turbo, you can cruise around town with no issue.

project x probably. I started my install a few days ago, got a lot done, but its been hard to find time the past few days to work on it unfortunately. When are you thinking of tuning, and where?

same, eli @ project x. i need to put a bunch of miles on my clutch before I go, but i plan to do that quickly LOL

yea haha, I'm going to install my clutch at work once I finish the kit at home, then I have to break it in as well. Maybe it will work out and we can do it the same day. Just depends on how much time I get to finish installing everything. I have suspension, engine and trans mounts, and diff bushings as well to install when i'm done with the kit...

Well gang. Ill be joining you very soon.

My turbo and other parts showed up today!!!! WHOOOOP!!

Im like in the BP round 2.5 list though..lol...

My car is sitting on jack stands already with some head work out of the way. Plan on having it done mid April then putting 500 miles of clutch break in then Dyno. This will be on E85 with loads of timing for quick spool.

Cant wait!

If all goes well I should be done with the build Easter weekend. Clutch will be broken in by the end of this week so I'll be able to see full boost as soon as I do the check-out and leak testing.

we got my z in the air tonight and took a inventory of parts/ laid them out for the build. will follow the instructions up to taking the exhaust apart, once at that stage we will drop the trans and put in the clutch kit before finishing up on the turbo kit. tare down begins tomorrow

Congrats!

Is the tap included with the kit (and the barbs supplied) 1/8NPT?

Yes.

Thanks Sasha. Figured it was but wanted to double check before I pulled the trigger on my Amazon order for a couple additional barbs.

Do it! Your car will be a highway beast!

:iagree: I am itching after next weekends event at Pocono Raceway my GTM TT kit will be for sale.

Do it!!

:iagree:
Dooooeeeeettt!

I missed a step somewhere. Aren't the turbos you have good for a lot more than the 15(?) psi you're running them at? What do you gain by swapping kits that couldn't be gained by working with the existing one?

The combination of small T25 housings and poor design/flowing manifolds will limit maximum power. So you can put whatever turbo you want on there, you will always be limited to the turbine housings and manifold design.

If you compare any manifold to the F.I units, it is very obvious which manifold will flow more/better and produce much better results.

Remember this picture I took:

T25 .63 a/r turbine compared to a Precision T4 1.0 a/r (that is only a 1.0 a/r housing too, they go up to 1.32)

Whatever air the compressor pushes out, the turbine has to be able to handle as well.

Agreed, but it would seem there's a lot more left in that kit and those turbos before you hit the wall.

The turbo I have now are rated at 480 each but I am held back by the log style manifold that come with the GTM kit and the small .64 A/R housings that I have on the car now.This is the reason I have been stuck and haven't ran anything more than 18-19 PSI. It is just to much backpressure from manifolds and housing's that I have on the car. I could just change the housing's with the manifolds I have now but the motor has to come out to do that. Pulling the engine in and out on these cars with a TT setup is not cheap.

In the end I am selling my GTM kit because the New V3 manifolds have not come out and I have been waiting a year for them. I would love to have the new manifolds upgrade my GT3071r's turbo to HTA billet wheel's 640 HP each. This would be very cost effective for me but I am just tired of waiting.

Ah, I didn't realize you were running the smaller GT30s. That's definitely going to choke.

I have already hit that wall almost 2 years ago at 650whp yes I can push it more and go to 700whp maybe a little more. But I have choose not to push it due to all the backpressure to much of it is not good for an engine.

Yes this is what Sam sold me at the time I wasn't as educated as I am now. I know what I want and I know what well make power. What I really would like is TT kit that has good flowing manifold's and two GTX3076R turbos or a HTA3076 but that is not available for our cars.

So Boosted performance is leading the pack right now as the next best option.

Also keep in mind the gtm t25 on their exhaust manifolds were undercut by 1/4 of an inch.. Check out my pictures.

Yes I saw that to in your pictures.

:rock:

I started surgery today. I got everything off that needs to be off. My exhaust was a whore. I had to sawzaw the y-pipe off of the rear portion because of all the rust on the nuts lol. A 14 was too big and a 13 was too small. The demon bolt was surprisingly easy. Slowly but surely...

Sweet another BP build begins! Good luck my brotha
