I was trying to hook my battery up tonight after reinstalling my throttle body. The first problem was the positive battery cable wouldn't fit over the terminal no matter how hard I tried. I was finally able to get it on halfway. Then I hooked up the negative cable and it sparked and that was...

I recently got a flat tire and need to get the tire replaced because it can't be patched. My tires have about 50% life left can I just replace the one or do I need to replace all 4?

I agree, 30+ PSI should not be any problem. Just make sure you tune it well and you'll be fine on C16, may need to watch out with 112 octane or less if you mix it at 30+.

Try turning the boost down and then leaning it out more since you are still quite rich. 11.5:1 is pretty safe for the street and you're under 10:1. If you can get no knock with a good A/F then try turning the boost up until you start knocking.

I'm sure he typed the topic wrong since I don't even see how it would be possible to put the MAF before the air filter.

Slip fit is fine.

I have one, sort of. The adjustment bolt on mine stripped out the regulator because the nut they included was the wrong size so instead of the nut moving the whole stud turned and stripped the aluminum. I'm at school so I won't be able to fix it until May. This type of regulator won't break...

Yes you can if you remove the radiator, didn't try with it in. Only tough part is unbolting things when you have it removed but you could probably do it in a vice.Installing things is the same but make sure you attach the oil lines and water hard lines to the turbo.

The problem I had was the nut was actually the wrong size for the bolt on the regulator, at the store I found the correct size. Too bad I found out after I stripped the hole. I tried JB Weld but failed because I either misaligned the hole or broke the nut off tightening the bolt down. If I...

What if I JB Welded a nut on top of the regulator, then used a bolt? Do you think the bolt would back out over time?

Well pushing down with a screwdriver does change the fuel pressure. I'm waiting on an email from Full Throttle to see if I can tap the hole again or not.

After finally getting this piece of junk installed (fuel return line doesn't fit over the fitting), I start my car and go to adjust fuel pressure. Oops bolt turns and doesn't do anything. Look and see that the hole the bolt goes in is stripped so the regulator is worthless. Can I retap the...

For a underhood fuel pressure gauge mounted on an AFPR should I run a liquid filled guage or is any gauge fine? My Full Throttle AFPR is waiting for me to come home for spring break so I need to order a guage for it.

You need to adjust your throttle cable or TPS because you are not at 100% throttle.

Not too late assuming the car is in good shape. You probably want to check out the N/T Performance Section.

Well you make it seem like the TO4E is impossible to fit when the majority of T3/T4 users have the T04E, but anyway you are correct the T04B is an easy fit.

The T04E is the middle size, it fits with minor or no modifications usually. Sometimes denting of the water pipe or trimming/replacing of the passenger side fan is necessary. The T04S is the largest compressor housing and has more fitment problems.

If the RPM value is off by half then set it to 2 cylinders, common issue with 1gs.

I bet the reason why you trapped 1 MPH less is the car was slightly heatsoaked. A bottle of octane booster will make almost no difference, if you want to increase octane either use toulene/xylene or race gas.

Put a towel underneath because the black spacers fall out a lot and you can never find them.

You could try AMS, they've fabricated stuff for me before. www.automotosports.com

If you're changing out your whole fuel system you might want to go with a big inline pump but a Walbro 255 intank is more than most people need.

New manifold with a flange for an external gate/weld a flange on your manifold then weld the wastegate flapper door shut.ORRemove flapper, port hole, and then purchase O2 housing that you can mount an external wastegate on.

That way is good, but in order for it to be worthwhile you must port the wastegate hole out as much as possible so the maximum exhaust flows through it.

Well what he would do is run the feed line down to the radiator then back up to the turbo. It would be cooled slightly by travelling through the radiator again but I bet the difference would be negligible.

Probably .028, but you may need something like an MSD to hit 30 psi. Also I'm not sure if you want to run a plug that cold.

Looks good, but why exactly did you do that?

I always thought 1gs ran ~10-100% and 2gs are 0-100.

Yeah raising the idle is a good suggestion. Also, how long have you had the car running for? It usually takes my car 20-30 mins to idle well after I reset the ECU, during that time the idle will drop when I put in the clutch or rev it at idle.

Very helpful. If you can't pass with a aftermarket cat then there is probably something wrong. I pass w/o any cat at all. Check to make sure your EGR is functioning, O2 sensor is still good, etc.

He has a chipped eprom ECU, he is only using the S-AFC to dial it in precisely.

It sounds more like the car is missing. Fuel cut is determined by the airflow signal, but fuel controllers lower the airflow signal so fuel cut isn't hit so in a way going with larger injectors gets around it.

You were wrong, just admit it and move on. Talking back to a moderator isn't really a good move for someone who has been a member for 3 months.

With race gas and proper tuning you're fine. 6-bolts are good for 450+ hp.

All DPs are the same for turbo DSMs.

The exhaust housing also changes the sound, but I think you're mostly imagining the difference in sound.

My vc breather doesn't suck in any air at idle, that doesn't sound right.

There isn't really anything wrong with timing that high. However, the reason is that the 770cc injectors are causing you to take a lot of fuel out. This means that the ECU is seeing less airflow because of how the MAF-T works. The ECU gives you a lot of timing because it isn't seeming much...

The one I have is 2.25"

I'm not 100% sure so wait for another member, but I am fairly certain there is no difference.

MBCs that are designed to be run inside work just as well. The problem is when people take regular MBCs and run long vacuum hoses so that they can have them inside that they respond slower which can lead to boost spikes.

Standalones completely replace the stock ECU so you must tune every parameter (timing, fuel, knock timing pulling, etc.). The AEM is usually a plug-and-play setup, which means it just plugs into the factory harness so you would need to replace or repair the harness you have already. I know a...

It's either to just take a piece of hose and loop them. Some people cap them off and then change to the NT water pipe which has no feed.

It will throw a CE light if you run w/o the 2nd O2 sensor, but it will not go into any limp mode. The car will not run properly w/o the 1st O2 sensor though.

I really don't understand how you can possibly be spinning the tires at the top of 3rd gear on a 16g unless you run the worst tires in the world. I don't care what housing you have, it is just not possible. I run 19 psi on the street and I spin a little in 1st and thats it, but I run SO3s...

There is something wrong with his car if he is at -30 on any turbo with 550s. It doesn't really matter that much what turbo you have because the ECU corrects for airflow, so you will have to tune it a little with a new turbo but not more than 5 percent at any RPM.As for my low they are -8...

There are adapter fittings so that you can connect an aftermarket filter to the stock feed line. Most people replace the filter, line from filter to rail, and then the regulator and the line from the regulator to the stock hard return line. Nothing wrong with upgrading the whole feed line, it...

Sounds like boost creep to me, caused by your 3" exhaust. Try running a vacuum line straight from the actuator to your boost source just to make sure it isn't a bad actuator.

Mine are set at -15 all the way across on the high.

Does it go straight to 18 psi, or does it go to 14 psi then creep up to 18+? If it does that you have boost creep and need to port out the wastegate flapper hole or even get a 34mm flapper. Try running a vacuum line straight from the wastegate actuator to a boost source to see if you have a...
