I support leaving it alone until you have the cash to drop on building it + the FI kit all in one lump.

Get the engine completely built and ready (with a donor engine) and THEN pull your stock stuff and greddy kit, drop it in.

Glad to see your car is doing so well after so many miles. :tup:

Glad to see this ride still running strong.
I'm over 10k miles at 12lbs and car is still running strong. These motors are very strong with a good install and tune.

The VHR can definitely handle more HP than a DE in stock form. But... I bet a lot of that value is in the much much lower peak torque from the VHR. A DE with the same HP as my VHR, will make 125-150 more peak torque.

Last night, a friends 350z DE with about 40 more HP made 175 more torque (not stock rods/pistons).

My VHR is making about 120hp more than I pushed the stock DE in my 350z, but I think about the same torque.

I'm sorry to hear that. Any idea what went wrong?

How many boosted VHRs have failed so far? I thought it was only 3-4 but perhaps it's more?

I have a donor engine to build... But I don't think ill buy another turbo kit without selling this one first.. That would mean I have more invested in turbo system at once than my 52,000 mile car is even worth!

On my DE I stopped at 8lbs on a gt35r single turbo. But I knew the limit of the DE motor so I was at 420/400.
Witth my setup now I went with what my tuner felt was comfortable. 12lbs at 534/500. There isn't much info on the breaking point of the VHR. I think I'm the highest torque stock block. I drive my car pretty hard as well. My fuel was the limiting factor when tuning. All on pump 93.

Horriable install, fuel feed line and wire harness for the TB was not installed correctly and cause issues then BOOM.:icon14:

What are you doing differently that got you that much torque?


:ugh2: Come on man. You know better than to talk about that here. ;)

Looking forward to making it happen CJ! Thus far it has been great working with you.

Thanks, Tony

Lol sorry I'm used to being on my350z forums.

Freaking awesome!

That is great to hear she is running so strong still!

Do you think that running E85 may be factoring in on longevity? Maybe running cleaner?

This is probably a totally farce question, but I know you are probably one of the, if not the only boosted 70 running 85.

Definitely a factor, I would estimate.

Cooler burn, more wiggle room from the added octane.

I think e85 has contributed for me... But I don't think I am taking full advantage of it either. I feel like its more picking up the slack for me by being more forgiving and allowing more negligence, than it is giving me a major advantage.

I think my car could spool up better and make a tad bit more torque if I knew more about tuning with e85, tuning with Osiris, or both.

Since I am running the fuel system to the edge, which tends to cause cylinder bias, e85's resistance to knock will aid me in surviving through that. But then again it's e85s fault that I'm at the end of the fuel system.

I fuel starve my car ALL the time from hard right hand turns. No, I don't have the CJM road race pump in my car lol. The first batch sold out. E85s resistance to knock has probably helped keep my engine intact through that. Ill come into full boost on an on-ramp and suddenly go lean and starve... I don't feel like a 91 octane setup would survive that after a few times.

Premium gas and water injection should be able to make just as much power almost as effectively? I think that for over 550rwhp on pump gas I would want water injection.
