How much is E85?
In the United States e85 can range between $1.80 and $3.00 depending on your state, compare that to c16 which is on average in the $16 range per gallon and i can bet most of you would choose e85 for your builds.
What is E85 good for?
This cooler burn promotes a more efficient or "full" burn and decreases the cylinder temps inside of the engine. So it not only works to cool the engine but it allows for a much better condition for the combustion of fuel in order to support power. Here is an example. In the z32 Na-t group its well known that we are limited to low 400whp with na (10:5:1) compression on 93 octane because of the risk of detonation. But if you add e85 to the mix you can find guys in the 500+ range with na (10:5:1) compression without pre-detonation, e85 is in fact so good at cooling that it can even support a non intercooled setup on the 10:5:1 na compression motor up to around the 500hp range with stock twins. Even in Na applications e85 can allow for advanced timing, and a much more aggressive tune that otherwise would not be capable with pump gas.
How much octane to boost pump gas?
There are fuel octane boosters such as boostane, lucas fuel octane booster and a few others that can raise your octane level from pump 93 up to around 100 octane. This boost in octane level will allow you to run more power on pump gas with a high compression twin turbo setup.
Is E85 better than Q16?
A few of the key point (i will make a full guide to e85, and explain its uses in much more depth in a coming article), but a few key pros to e85 are as follows, drastically increases octane level, has a much more efficient and cooler burn in the combustion chamber, cools your engine, is very cheap compared to other race gases such as Q16, and because of these benifits allows you to run much higher boost levels, and increased timing to hugely raise your hp and tq output. The main con to e85 is that you will use approximately 30% more fuel, but for the power increase, safety and reliability it is completely worth that sacrifice.
Does 300zx make the same power?
Lastly not every single 300zx will make the same power with the same modifications. your engine health, air temp, altitude, quality of fuel, humidity ect all have an effect on the power you make. As always, continue to learn, continue to grow, and have an amazing day.
Is E85 good for cooling?
But if you add e85 to the mix you can find guys in the 500+ range with na (10:5:1) compression without pre-detonation, e85 is in fact so good at cooling that it can even support a non intercooled setup on the 10:5:1 na compression motor up to around the 500hp range with stock twins.

Nismo280zEd
Ok guys I'm having some problems sourcing the information I once came upon less than a month ago.
Nismo280zEd
I've never heard of sonic testing, can a typical machine shop do this? Sounds like xraying the block almost.
mtcookson
I agree, I'd definitely get it checked first to make sure it will handle that as many say the VG30E (T) won't handle the VG33's bore (I'm pretty sure at least some of the water jackets were designed a little differently in the VG33 for the larger bore).
Nismo280zEd
It's starting to sound like this motor is a big waste of time and money.
mtcookson
Yeah, if you're wanting to go NA the VG30DE is not the route to go. The VG34 setup is definitely a great, low cost solution to get some NA power but, like Richard said, even better yet would be the VQ35DE. If you don't mind going bigger with a V8 then you have tons of stuff to choose from to go NA.
Nismo280zEd
motor is pending sale, thanks anyways guys. I'll let somebody else pioneer this one, looks like KA-T for me.
mtcookson
Sweet! Good choice... I love the underdog engines like the KA and SOHC VG, they're my favorite.
