If thats what you are going for get some DEFI gauges.

A Mechanical gauge is a mechanical gauge. They all operate the same way. Personally I am a fan of VDO. I have used their boost gauges many of times.
No, xbg has much more money than me. Autometer gauges, not the high end ones, are reasonably priced. So Sunpro - $30, Autometer - $60 = worth it, IMO.

Ok. Boodt/vac and oil pressure tachs figured out.

Any suggestions on a Tach??

focus, no one is criticizing you for your build, but I will disagree that "a gauge is a gauge".

Regarding mechanical gauges, I'm not running fuel or oil into my cabin to make a gauge work, so I will stick with my sensors and electric gauges.

So, now that garrm let me in on that mechanical guage secret, I might go ALL-OUT and go PLX.

Will update soon.

By the time I buy all electrical guages I can get a nice PLX system.

Any1 familiar with PLX and ther sensor module hookuo?

That is why we replace the rods and pistons if you are serious about power and your project.

Good aftermarket pistons/rods can with stand much more stress.

I know as I am not a big fan on meth.

I'd rather pony up for CP pistons and Crower rods:)

Yeah I'm not offended or anything. We're all welcome to our opinions, I'm mature enough to deal with people disagreeing with me lol.

This was a pretty big fear of mine, and one of the reasons why I didn't immediately spring for meth injection. That's just pure speculation at this point though, isn't it?

I could have sworn Morgan or someone ran an SC with meth injection... Can't find info on that now. Anyone know how that went?

Yeah, but do we KNOW what it does to out engines in terms of damage?

Might be something there.

Besides, pistons/rods is the way to go if you are worried about blowing an engine.

Has anyone poped a stock motor yet???? If so, what kind of boost/horsepower were U making???? I plan on buying a junk yard motor next year and packing it with better internals, but I'm just curious how far the stock motor can be taken. Any one Bueller, Bueller?

She did, and it cured detonation problems. Meth injection can be used for more mild purposes, guys, not just big power.

Garm drove around for 8 months @ 180hp. Thats 90 more whp than stock. IMO thats about as high as you want to go.
Lost just a bit of compression in one cylinder over that time, too. Of course, that was only roughly tuned, so I can't point at a single exact cause.

to answer pimp's question. I don't know anyone who has blown up a 1.5L motor -- although I think Tamago threw a rod, as I recall.

Easily forgotten... lol

I run meth with a S/C, and I am the only S/C'd yaris that is re-tuned with meth ( let alone re-tuned). I'm running straight meth, no 50/50 mix.

I've blown one of these motors

Was using the Blitz S/C and Nitrous. Forgot to purge the nitrous bottle pressure down before launch and BOOMMMMMM!

Bottle pressure was at 1600 from sitting in the heat needed to be at 1000, but that my own fault. snaped 3 rods and turned the piston 90 deg. in the block. I have the rods and pistons at home as a reminder of what not to do.

You my friend need to just start your build. For someone on a budget your looking at parts that go way beyond your means.

As far as PLX goes I use their AFR gauge it's deadly accurate.

As far as meth goes great way to keep you from detonating and run smoother. You can get an octane rating up to 101 with meth and 93 pump gas. Thats what I've been using. Best bang for the buck. I've switched to a race fuel for this new build but I don't drive this as a DD.

My ride with all that high end fancy shit has put me in the 60,000 price range on my build. But I;ve had the money to play with.

I think more. I can run up to 30+ psi with 50/50 water meth. You can't be saying I'm doing that with equivalent 101 octane.

I don't think you've said definitively how much boost you are going to run. You may not know yet. Boost level will determine fuel needs which will determine injector choice, need for a pump and possibly return line, etc.

It depends!

You guys are going to start loosing teeth and get "meth-mouth" with all this "pure" meth talk.:(

lol HAD to do it...

Anyway, does anyone here have anything to say about CP pistons? Good/reliable? Not so good? Good but overpriced>

TIA
