IPT valve Body for $499

Has anyone worked with this company?

http://www.importperformancetrans.co...uto.shtml#main


They also has a solomoid upgrade for 189.


I wonder if there's a need for both?

I have. But their website doesn't even list a valvebody upgrade for the 350Z/G35. Like you, I have an automatic and intend to beef up the tranny. I'm gonna wait and save up for the transmission upgrades offered by SGP Racing. Check out www.sgpracing.com

Their valvebody upgrade is priced at $1,000, but it's supposed to be good for up to 550whp. They also offer torque converters and full tranny builds. They're developing a full auto tranny upgrade to withstand 850+whp!

Just purchased IPT VB upgrade online. Project will be done in 1-2 weeks.

I have done enough reaserach to decide that IPT is the way for me.
I have read all the VB posts on SGP, L10, Stillen & Sharif's FP.

Just the plain 499,

They charge $25 for 2 say shipping but also gave a $25 coupon by sign up
their mailing list.

I will give review when it's done.

ma sha1> did you ever find out the differences between the services performed by the different vendors? or is it nebulous/proprietary that they were unwilling to disclose? (e.g. modifying tcm, increasing line pressure, changing solenoid, changing cooling, changing clutch packs, etc)

if u didnt upgrade the solonoid then what makes this VB any difference from level 10 and stillen? I would think the upgraded solonoid is the reason for the crisp shift.

I am listing what I learned so far:

modifying tcm: None of the VB upgrade does that.
increasing line pressure: Every VB upgrade start with this.
changing solenoid: SGP & IPT (Optional ). Sharif (Not confirmed, but frequently claimed with a general statement: "same as SGP".

changing cooling: That's by External Tranny cooler, not VB upgrade.
I installed a Trannt T. meter instead.
I am at 125 degrees, no need for a cooler yet.

changing clutch packs:
None of them does that as part of VB upgrade.
IPT & other transmission company could do it with
$$$.


I don't like vendors hide under the term "proprietary", which translate into plain english terms = "If I disclose it, it'll have a negative impact to my business".

Also, I am not doing solonoid, even thou IPT offers it as an option.
He told me it's only needed fro high milage cars. (>100,000 miles)

The difference will be $$. Probably not performance.

I have to take my whp into account. If I have TT & gets to >400whp,
I may go to the quickest shift, probably get SGP.
I am at just over 300whp.

For me, the VB choices should look like this"

<250 whp Stay stock
250-350 whp: IPT, Stillen, L10 VB upgrade, line pressure only
400-550 whp: SGP
350-400 whp: may go either way
>550 whp: need more tranny work than just VB
