I've searched the forums on head gaskets but can't seem to find a straight answer on what is the best head gasket to go with if you have an O-ringed block. The engine specifications that matter are:7-bolt, 10.5:1 compression, 40-50 psi, O-ringed block.

I am looking for a vendor who currently has the following Spark Tech system in stock:Spark Tech DSM/EVO 1-3 PRO CDI COP Model: COP-DSM12FThis is not the one that extremepsi.com sells. If anyone has advice on who might sell that product, please let me know.

I had a loud squeaking noise coming from the engine, and I thought it was a belt. The belts are in good shape and plenty tight, and then I noticed the drive pulley was wobbling. I traced the noise to this. Then I thought it might be a bad harmonic balancer and searched some threads on here...

Does anyone have any personal first-hand experience with aftermarket torque converters? I've read about the IPT billet torque converter, but haven't been able to find much information on anything else.I know there are a lot of factors that go into torque converter selection, but the basic...

FIST Racing in Houston just completed a large list of bolt-on parts to my otherwise stock setup. You can see the details of my car in my profile, but it's basically bone-stock from oil pan to throttle body, with the exception of ARP head studs. The rest is just turbo, intercooler, fuel mods...

Well, as the title asks, how much horsepower can the stock bottom end of a 1998 4g63 handle (safely)? I'm about to go to the dyno for a tune on a recent bolt-on build. It is a speed density setup now running on e85, if that matters.I've been searching the threads and have read 450 hp, to 530...

I installed a Hallman MBC, correctly I'm pretty sure. I installed it according to the following thread:http://www.dsmtuners.com/forums/articles-turbo-system-intercooler/237982-best-way-install-mbc.htmlThe car is pretty much all stock, 2G, stock turbo, stock BOV.To start, I backed...

Sorry if this has been answered, but I couldn't find it. I have a pretty much stock 2G, and I have a 1G bov that I want to put on. I need the flange adapter that will allow me to put a 1G bov on a 2G intake. Where can I get said adapter?

The car - 1998 Eagle Talon Tsi awd, all stock engine, auto transmission, boost gauge installed, air filter, 3" exhaust, no cat. The rest is completely stock.I've been chasing this problem for months now and I'm running out of ideas. Here's what's going on:When I hit full throttle, as...

At 142,000 miles, I'm having minor issues that are leading me to believe that my coil(s) are not up to par. So I was thinking of replacing them. I know that the stock coils are pretty good, but is there anything else out there that may provide a stronger spark? 4G63.

In 2006 I sold my '95 Talon TSi fwd and have been out of the scene, until this weekend. After my long extensive search, I finally found THE car. And in Texas, DSM's aren't very popular so they are few and far between.It is a 1998 Eagle Talon TSi awd automatic with leather. Timing belt...

All right, as the title says, my new endeavor is to convert my fwd TSi to rwd. And I don't mean awd, nor do I mean awd with the front drive shafts removed. I'm talking about turning the engine length-ways like it should be, tranny, driveshaft to the rear, differential and suspension.Don't...

I put my car together last night from a 2 month break-down. I'm not a newbie when it comes to timing belt installation and tension setting. Drove it around for about an hour to check things out, get home, things are fine. This morning I go out, pop the hood and grab the timing belt between...

Hey guys, I'm working on a website that I think could have a lot of potential. It's all for fun, and you could win a gift certificate to a restaurant of your choice. Just tryin' to do something productive with my late night internetting!Go to here: www.playwithmyfood.com

I finally got a decent run at the track. I wanted to post a pic of my timeslip so I can submit it to the archives.FWD can be frustrating. I got a pretty decent launch, my best ever with a 2.146 60'. After I get going, my car really runs strong. I was searching the archives and noticed...

My mind is still spinning with all of the drama in the "Will It Fly" thread, which was a simple trick question that only like 20% of DSMTuner's members got. But it reminded me of a real good riddle that I want to try against you guys.You are in a room with no windows and two identical...

Is it possible to read TPS voltage with my SAFC? I'm not talking about 0% - 100%, I'm talking about the actual voltage the TPS is putting out.And if it is possible, then what should the TPS voltages be at idle and at WOT?-Thanks

I have been unable to locate a window switch for a nitrous system that operates according to boost. My goal is to install about a 50 shot that operates only at WOT and when the boost is BELOW 15 psi. Then, once the boost reaches 15 psi, the nitrous cuts off.Seems like a pretty simple thing...

I have gotten a few positive reviews on the SAFC and Wideband gauge install I did in my center A/C vent area. It was requested that I post a "how to" on it, so here it is. I wish I had more pictures other than the final product, but the instructions are pretty straight-forward. The end result...

Has anyone seen that video of the 350Z at Houston Raceway Park racing what appears to be John Shepherd? I've watched it over and over again and the car looks identical to John's, plus it moves like John's. But I have never heard a thing about it.If it IS John, he is racing a twin turbo...

I am running a Garrett T3/T4, Tial 35mm wastegate, GReddy BOV, plus other mods. I usually run around 21 psi, and things have been fine. Then the other night, I only hit 17 psi, so I gave it another run and only hit like 13 psi. I pulled over and couldn't find the problem.The wastegate is...

Here's a couple videos of a run I made last month. It was my first run of the night, car wasn't tuned properly. Hey, don't we always have some excuse? ;) But seriously, it wasn't, as you can see from the knock count (the upper number on the SAFC). You may not be able to read the digit...

I need to limp my car to a shop with the turbo not connected to the intercooler piping. Will this damage the turbo?

I've heard a little bit about IPT and visited their website. I've searched on DSMTuners a bit too and can't find much info.I'm building a race-only '93 AWD Talon, and I am looking for a GOOD, strong, fast-shifting automatic transmission that can handle around 700 hp. Does anyone have any...

I was wondering if it would be OK to just run race gas all the time in my car. Keep in mind I only drive it like 1 or 2 days a week when the weather's nice, and only for fun.If I just kept race gas in it all the time, would my plugs suffer, or my O2 sensor, or my wideband O2 sensor? Does...

Just searching around the internet and came across this. A guy has a GSR with some mods, not too many, and asked if he should race this guy with a turbo Eclipse for some money. All of the responses were in the Eclipse's favor, and they all went something like this-"I wouldn't put down any...

Well, I never buy a game before I rent it, but for some reason I did this time. What was I thinking? L.A. Rush sucks. Maybe I'm spoiled by GT4 or something, but L.A. Rush is the most unrealistic, unresponsive car game since Atari 2600.Anyone else feel the same? I'm using the Logitech...

I've been searching all over the internet, including the NHRA website itself, and I cannot find the rules and regulations for building a car to spec. I did find what I am supposed to wear, but nothing about what the car must have.My wife will tell me I can't find anything when I'm looking...

I have been running a crappy header that I bought from someone here on DSMTuners who really stuck it to me hard. This weekend it finally cracked, as I knew it eventually would, after only about 1,000 miles.I've heard that headers for our cars usually don't last very long for some reason. I...

Went to the track last night. Had one problem after another, sucky night. Anyway, to top it off, I hear this gunshot from under my hood, and this is what I've found. That first picture is the bottom of my intercooler.Could this possibly be the cause of a severe boost-leak? OMG I can't...

What is the best way to vent the crankcase? I believe that I am having a problem with mine. I get lots of oil out of the oil cap, and so I bought a new cap, and still have the problem. I believe that I am putting pressure into the valve cover when I build boost and it's blowing oil out of the...

I can't get my car to idle right. It is low, and I don't think the a/f ratio is correct. But then I was reading that the ECU will automatically try to achieve stoichiometric, and my wideband O2 is registering between 14 and 15. If this is true, then why do we have the capability to tune the...

Man... I just came from houston-imports.com forum, wanting to try out a local forum so I can meet some locals. In my 2 hours of being on there, probably like 5 people are talking so much crap to me it's making my head spin! I mean, for no reason! I say "hey, what's up, new here... etc." and I...

When installing the GM MAFT, is it necessary to run the white wire to the tach signal, or is this just so that you can tune the MAFT according to RPM? I have an SAFC-2 so I will be doing my RPM tuning through that, so if it's not necessary for normal operation to the MAFT, I wouldn't need to...

Should I set up my GM MAFT settings so that the car runs with a pretty close to perfect AFR with my SAFC-2 set close to 0, and then fine-tune it with the SAFC-2? To me, this would seem like the way to go. It would be like having a stereo with an aftermarket seperate equalizer, setting the...

Some of you are old enough to remember and appreciate the only good thing Buick ever did for the automotive industry, the Grand National and the GNX of the '80's. In 2007, the GNX is back! Looks pretty cool, and has stats to back up the GNX name.General Information Price: $38,500 Miles...

I absolutely cannot figure out the instruction manuals for the Innovate LC-1 Wideband and the Innovate XD-1 Digital dash display.On the LC-1 there are 7 wires, and the instruction tell you what they are, but I need more info. Questions I have are:Analog out 1, 2, and ground - Will I not...

If I have a wideband O2, is it necessary to have the original O2 sensor? Keep in mind that I do not have a catalytic converter and I have a rear O2 eliminator. So I only have the 1 O2 sensor that is up close to the manifold. But since I have a wideband, why do I need the originaly O2 sensor...

Yeah, I know. You stick it in the gas tank. But I mean, if I am to drive down to the track and put it in the tank at the track, what is a good mixture of 93 pump gas and race fuel, and what race fuel, etc.? i.e., 5 gallons 93 with 2 gallons 115, or whatever.Never ran race gas before and...

What is the stock fuel pressure on a 2g? I think I remember hearing it is 42 psi at idle, then should increase about 1 psi per psi of boost. Is this correct?I have a Walbro 255 plus loads of other mods (check out list). It seems that everyone has been telling me that I will overrun my...

I know that I cannot reach full potential without a logger, but I was wondering how close it is possible to get by tuning with an SAFC-2, EGT gauge, in-car fuel pressure gauge, and a Wideband? It would seem to me that, if I can get the a/f mixture right throughout the full rpm range, then it...

Does anyone know of a really good place to go that knows a lot about our cars in the Houston area, or even Dallas or San Antonio? I feel that I am reaching a plateau in my tuning knowledge and I am ready to put it in the hands of a professional for fine adjustments. The only thing I really...

A few months ago I posted a picture of the simulator I built with my old DSM seats and said that I would have a projector screen soon. Here's a picture of it finished.This picture is a few weeks old, and not pictured is the other steering wheel so both players can drive, in place of that...

I have a stock fuel pressure regulator and an Autometer fuel pressure gauge. It's the remote gauge that mounts inside the car so there is a sending unit. The only place I can see to mount the sending unit it would possibly be by replacing the nut on the top of the fuel filter with the sending...

No, I'm not going for the most awkward question asked as DSMTuners. Just wanting to do something different. But seriously, my wheels are 18 x 7.5", MSR type 103 with 225/40-18's. The tires are new as well as the wheels. I've been wanting a change but I just bought them, so I was wondering if...

A little long, but an unbelievable story.My friend and I searched and searched for over a year for a 1992 Z28, low miles, excellent condition inside and out, near stock, fair price. As easy as this may sound, it wasn't. We finally found one in Wisconsin (we live in Texas), and got a...
