So I have the SFR stage 2 turbo system headed my way. As you may know it is designed with the 5.5gen in mind so I will be making some changes to adapt it to my 4th gen. Once I have it all installed and reliable and have recouped financially I will be building the 3.5 I have in the garage for boost and swapping that in... I will create a build thread once I start to make some progress... For now I am trying to decide which IM I should use on my 3.0. ATM my 3.0 is bone stock and I'm faced with:

1 - Use the 00VI I have lying around and adapt my charge tube to fit.

2 - Get out the die grinder and cut my heads to adapt the SSIM.

So far I'm thinking SSIM so I don't have to change my charge tube again down the road when I go 3.5. Not to mention larger plenum, TB, etc... The only thing that worries me is the limited information available on the SSIM/3.0 setup... And spending all that time hunched over my car porting my heads on the car.

My questions to you maxima.org are as follows..

What would you do?

Are there any threads other than this that I am missing?

Any other comments suggestions?

 

Why would you need to adapt the charge tube? The TB is in the same location on the 00vi as the 3.5IM.

 

This I was not aware of.. So charge tube modification aside then, what would you do and why?

 

IM's are so mainstream.

No IM for moar powah.

 

00VI will provide you with the best powerband, hands down. My power band was better on my 3.0/00vi than it was/is on my 3.5 with 3.5 manifold.
SSIM in my opinion is overrated. you'll be very happy with the 00VI.

 

my inclination is 00vi, though i haven't done exhaustive research on it.

 

Wow just noticing that you ran 14.5 psi on a stock 3.0 with USIM. Is that motor still around to tell the stories? I'm not being smart I really have no idea how far I can safely push this machine I'm building....

Thanks for your input, I think I am going to start with the 00VI and see where this takes me. Now - to power rod or not to power rod? My gut says start with it in.. Will having it closed in lower RPM help me spool faster?

 

I run without the power rod, feels better in the mid and top range

 

If you already have an 00VI its really not worth the effort for maybe a 5-10whp bump in power or maybe even no power gains at all and a worse powerband. If you have the SSIM and you are broke and have the tools, top feed injectors, 3.5 Fuel rail, 3.5 LIM, FPR already then yea go for it.

When i was NA with a SSIM, i was pretty torqueless down low. Car felt like it had a honda powerband

 

Currently I am bone stock. I have an 00VI, an 03IM (on my 3.5), and an SSIM with LIM, injectors, and spacer is coming with my kit (came off a 5.5). Sounds like I am going to go with the 00 for now though. Seems like less work and better powerband. Easy decision.... I think!

Can't wait to get this thing going. Kit will be here on thursday, just need to find an EU, WB, and some odds and ends.

 

00VI....hands down

 

Just remove the power rod so you won't have to run any rmp switch ect...

 

no. i changed some exhaust stuff which changed how much boost i got with whichever setting on my boost controller, so i ended up in uncharted territory on my boost controller and I accidentally overboosted it to like 18psi, a level which I never intended to be at so it was never tuned for that much boost, and I melted two pistons.

if i had just stayed at 14.5psi i don't believe i would have had any trouble with it at all, i believe a VQ30 can be run at that boost and a bit higher level reliably. I was probably around 420whp and 420wtq at that boost level I would guess. I believe a VQ30 can be run at 450 perhaps even 500whp with the proper setup and tuning reliably.

 

One day hopefully sooner than later...
