I removed my power steering and AC at the same time, significant gain at the track but I'm betting it was mostly thanks to the power steering. I don't miss either, especially since there's so much more room in the engine bay.

I realize that, but in my case, it's obviously not making a 20-30 hp difference.I do, and I'm still on the 14-year-old stock alternator (and cooling system).I'll consider myself reading challenged, as I was applying your statement to the stock manifold. Dur...Well I'm using a...

Yeah.

I mean studies that I've read about. I haven't witnessed any actual tests, but I have spent hours and hours on the internet trying to learn as much about oil as possible.Yeah, it does sound like a commercial now that I reread it, but I didn't mean it that way. :) I usually don't recommend...

Gap should be no wider than .028". My car will blow the spark out under boost every time if they're gapped much wider than that. I like to run them a little tight.My experience has shown me that no matter what anyone says, unless the spark plug is in my hand and I'm staring at the gap, chances...

Tell me about it!And before it does, you're getting inadequate lubrication. Most engine wear actually occurs while your engine is warming up.So? Plenty of people have wiped bearings for numerous reasons. I've been using 0W-30 in my car for almost 10 years now, without any problems...

Bull****. I've got no heat shield on my manifold, my turbo, or any of my exhaust, and I can guarantee you I'm not losing 20-30 hp (350 whp on a small 16g). I have plenty of top end.I bet I could probably gain a hp or two by adding some shielding but I'm too lazy to do that at the moment...

WHAT IS THE GAP ON THE PLUGS?I guess you missed it when I said "the first thing you should have done was check the plug gap."

Did you contact YOUR insurance company? That should have been the first thing you did. Your insurance company will tell you where to get the estimate from and will cut you a check to get your car fixed while they deal with the other company to get them to pay for it. Trust me, your insurance...

I usually gap mine to about .025" or so, but you can never trust pre-gapped plugs. I've seen them come as high as .040". Most of the time they're not even consistent across the set. Regardless, I believe the spec is .028" and that's as high as I would go. I know my car tends to break up if the...

Okay, but that's a simple matter of changing the plug wires.

Because there's no reason to ruin a perfectly good Tial 50mm by hacking it up to make it recirculate. The BOV wasn't designed for that.I wasn't arguing that someone who didn't need the flow capacity of a larger BOV has any reason to vent to atmosphere. What I'm saying is that there are some...

Yeah, I'd say so. The problem with fuel cut is that you're still going to get some fuel into the cylinder. For instance, on a batch-fire fuel injection system, all the injectors fire at the same time regardless of which valves are open, and the fuel pools at the valve and enters the cylinder...

That's closed loop. The ECU goes to open loop at WOT and ignores the O2 sensor voltage. The reason for this is what I stated before: narrowband O2 sensors are ridiculously inaccurate in determining how rich the fuel mixture is. They basically just switch voltage around stoich.

I don't see what you're getting at, because you originally stated that there wasn't an excuse not to recirculate. Certainly, on a high-horsepower car pumping tons of air, the need to release a large volume of air outweighs any need to recirculate.I agree with you: the majority of street cars...

I run a Walbro and I have never had any problems with it. I'm not doubting the reliability of the fuel system, I'm stating that a failure of the fuel system results in catastrophic damage when meth is being injected. Lucas' car was just one example.You're correct, most windshield washer fluid...

Exactly, but that's not what you said. You said that all BOVs can recirculate.

I've never seen anything that would indicate the coils are any different.

Yeah, right. I'd love to see you weld an aluminum body around a Tial BOV.You've never seen one of these before, have you? TiAL Sport.com

My 2g stock injectors were black, like those.What is the difference between the blue and black top DSM injectors? - 3SI Wiki

It's not the reliability of the methanol kit that's the problem, it's the reliability of the fuel system. Last year, Lucas English was running meth instead of an intercooler and lost an engine due to fuel pump failure. The meth system was still working just fine... and that's the problem.

I agree with DSM1G90, that oil is too viscous to use. I use 0W-30 in my car, since the winter weight allows the oil to flow a LOT better when the engine is cold, one of the most critical times of engine operation (after your car has been sitting and all the oil has drained back into the pan)...

When did Injen start making them without recirc tubes? I ask because the one I bought 10 years ago had a recirc tube on it.I switched back to the stock snorkel a long time ago and use a modded 1g BOV recirculated. That thing is extremely loud. I definitely wouldn't need it any louder than it...

What the hell is that supposed to mean? Nitrous adds oxygen to the engine. A turbocharger does the same thing.All liquids are essentially incompressible. The problem with meth is that if the fuel fails, the meth keeps spraying. I would definitely not rely on spraying meth on a daily driver...

A 16g on a good setup running high boost will easily exceed 90% IDC on 550's. Ask me how I know.You need something to tune with.

RBs are overrated. Not that they aren't incredible engines, but there are much cheaper platforms to build power with. Personally, I'd go with an RX-7 with a 4g63 in it.

The first thing you should have done upon noticing misfiring is to check the spark plug gap. Hell, while you're at it, you might as well just put new plugs in there. The lack of a rear O2 sensor is NOT going to make the car misfire.The '95/'96 ECU uses an inverted CAS signal compared to the...

What is your spark plug gap?

Tein S. Tech springs may be an option, but I second the recommendation for their coilovers.

Has anyone ever done a back-to-back comparison of power with stock-sized valves versus 1mm oversized valves? I find it hard to believe that they would make a significant difference on the average engine, especially with the stock bore. Granted, I haven't really been doing much with DSMs in the...

I take it you're keeping the Tokico blues?I've had a couple different setups on my car: AGX shocks (the original flawed version) with crappy coilovers of a brand that I don't want to mention, AGX shocks (the updated design) with a set of no-name ebay coilovers that were actually better than...

But exhaust gas heat is going to be affected by the air/fuel ratio, timing, etc. If you've optimized fuel and timing for the particular setup using the same tuning methodology, I doubt you'll see much difference in exhaust temps. Even if optimal tuning for two different compression ratios didn't...

I agree, although I'd go a step further and say why not upgrade the valve springs and retainers and go for an aggressive cam while you're at it? If you're using the stock valves, you still don't need to take the head off. I'd go with an aggressive cam and test how it works before even thinking...

It's not compressor surge, it's BOV flutter. The spring is shutting the BOV, which raises pressure, which causes the BOV to open. Lather, rinse, repeat, many times a second.

No, don't get me wrong, I don't dislike it, but I don't see the need for it if one already has a 2g manifold and is willing to port it themselves.I'll admit that I spent quite a while porting my exhaust manifold, as I went a bit down into the runners, but I really enjoyed it.

Compression ratio does not affect spool at all. Higher compression ratio makes an off-boost engine more responsive, so it takes less time to get there (and seems like it is spooling faster), but the turbo still spools at the same RPM.

There's two connectors in the engine bay, one for each fan. Connect blue to blue and black to black. I'm still using one of the stock fans, but I'm using one exaclty like yours on the driver's side, from Summit Racing (by the way, they have instructions available on the web site).My fans come...

I'd go with the smaller one. When you start making the engine breathe better, you're getting more flow at lower boost pressure, which means you're moving to the right on the compressor map. Go too far and you hit choke. You're going to want to minimize pumping losses as much as you can to most...

The wrist pins are also 1mm larger in the 7-bolt engines.If you ask me, the 7-bolt 1G engines are the worst of both worlds. Skinny rods and none of the benefits of the 2G engine, like the higher compression and smaller intake ports. I love my 2G 7-bolt.Also, I think it's fairly safe to say...

Of course it's going to feel good, because you just bled it.The easiest place for it to leak is the seal on the master cylinder. Save yourself some trouble and stick your head under the dash. You should see some clutch fluid around the seal. Otherwise, it'll keep leaking out after you pump...

Back the train up. You're not reusing the stock head studs, are you? The stock are stretch-to-fit. That's the entire reason to switch to ARPs, because you don't have to replace them every time you take the head off.I've run 20 psi on my car for the last 50k miles or so (over the past 8...

It's a cylinder misfire. It also sounds like your throttle is sticking.

I don't even have my fuel pressure solenoid plugged in. I've never gotten a code for it.My car gets cylinder misfire every so often when it's cold. What all did you touch when you did the alternator install?

What are you talking about? Do you realize how ridiculous you sound? You're the one who was completely ignoring "power output per CFM":Do you even read what you wrote before you hit the submit button? Displacement has NO EFFECT on CFM? Seriously? Because I would swear that a 5L engine...

How so? The same two engines at different compression ratios are still consuming the exact same amount of air (compression ratio has no effect on displacement).LOL Your 2-year-old thread.This thread needs to die.

WHICH POPULAR DSM TURBOS ARE ONLY COOLED BY OIL? Way to avoid the question! The reason I'm asking is because you're making blind statements that don't make any sense. Yes, I know it doesn't matter when we don't know what turbo he's running. So since 95% of the DSMs out there are running...

My brother lives in Fort Worth (not sure where exactly that is in Texas), but I've never been out to visit him.You said the only useful thing would be a logger, but it'd also be useful to have a wideband O2 sensor and a way to adjust fuel and timing. If you want an easy way to tune, DSMLink...

By the way, the only way you could calculate airflow from a specific boost level is if you knew the shaft rpm of the compressor and had a map to read off of. 7 psi on a stock 2g head (for instance) isn't nearly the same as 7 psi on a Honda K20 head, even with the same compressor.

Okay, well you brought it up:Bench race much? You're comparing apples to oranges. He said his friend was running a 2001 Civic Si with a fully built Type R motor. The 2001 Type R had a K20A if I recall correctly. That engine puts out 220 hp naturally-aspirated. Not to mention that the...

Well did you try PMing Tom or Dave on the forum? I've never had to wait more than 12 hours to get a response from them. I find it odd that you can't get in touch with them after you bought a legitimate product.
