To comment on the dual widebands. While this is a street machine, a dual wideband should be considered. There are 2 seperate banks and only 1 sensor, sonthing does not make sense to me there. I would want to know what each bank is doing. Your build and ultimately your money. I would take the advise from z350boy and that phat04350z to be safe and monitor each bank seperetly

EDIT: Wish you alot of luck and future enjoyment with your car. So you are not doing the build up yourself?

The thread got so slow I thought it was locked for a second.

Oh Zivman: The countdown also reminds me of how close I am from seeing my wife again. Don't know if you served or not but if you haven't try living 18+ hour flight away from your family & friends, surrounded by idiots. All I have is my wife, family and looking forward to driving my car with my wife to keep me going over here. So if a countdown is pathetic, than so be it my pathetic way to keep my head up in a pathetic country. [/end]


Back to the build.

I merely posted in an effort to contribute to the thread in a positive way, especially as Robert_K and I have very similar set-ups. As I stated I am very surprised at the hostility in this thread towards the idea of dual A/F gauges. Knowing that a stock block is running boost it is critical in my opinion to have real time information that can help prevent an over boost situation leading to a blown engine. With the expense involved in a rebuild I feel the cost of duals A/F's is reasonable. I cannot and will not force the issue upon anyone. All I can do is present information for others to consider.

Looks everyone... This is my build. I've done a lot of research and have received a lot of help. the built motor has been covered. I'm not going to build my motor and IS NOT needed for a low boost build. I've discuss it with several vendors & owners, and I think someone's mother. This thread is turning into a "Well I like this, so you should've done it my way." No! I'll listen to TRUE recommendations.

The latest from JWT is that there might be a considerable wait for
the 530 turbos, but that they can ship the kit with the 700 turbos. I just wanted to make sure that you are on-board with this, and I can get the kit shipped tomorrow, which will give us the time needed to complete the IC coating.

I had a lenghtly conversation with Nick about the prospect of using
the 700 turbos instead of the 530s. To explain, the 530s are the
Garrett GT2554R which make full boost on the VQ35 (6.5psi) in 4th
gear at about 2800 rpm. The 700s are the Garrett GT2860RS which make
full boost about 300 rpm later (still VERY low rpm). His opinion is
that you will get more midrange (especially with that Cosworth Intake
plenum, which is a better match to the 700s than the 530s), and
better top end (which MAC will control by proper UTEC tuning). We
still keep the boost pressure very low to get the safe power level we
discussed (420-430RWHP). Really don't see ANY downside, but we want
your approval before we tell them to ship.

Please let me know, or call during business hours to discuss. Really
don't mean to throw a wrench at all, this is just an alternative that
is worth more to you - lucky you.

Those 700bb are awesome - I guarantee. I'm sure if you speak to Jim Wolf you can request different waste gate springs depending on your comfort level - worth a shot.

Good luck bro!
