Have you done a compression check on the motor since you got it?

I got a remaned one from Napa w/ a 3 year warrenty for $140 something

Ok i replaced the alternator the other day and everything is running perfectly again:thumb:

I have been getting odd voltage readings lately and am pretty sure it is the voltage regulator inside the alternator, but wanted to throw this out there to see if there are any other possibe answers.My car is a U.S. 91' Talon Tsi so it doesn't have the 90amp alt. like the canadian one. I...

I think I remember reading about some 1g 4g63 2L heads have a 1.8 stamped on them, in fact i think i may have one at home, if i do i'll take a picture and post it.....Is the head at the junkyard a DOHC? anyway i'll see if i can my other head with 1.8 stamped on it.

I'm sure you probably already checked this out cause you know your way around dsms but Is it the shifter linkage? If the clutch is in and you start it in 1st does it move? i know may seem dumb just throwing stuff out there that hasen't been mentioned yet.I mean how do you know it won't...

1)This is the first i've ever heard of it....if you can will you show me where others have written about it, i'd like to read what they had to say about it also.2) Good point but this was purchased before either the EMS or DSMlink were popular for our cars.8psi is the max i can get on...

I've had this mod wired up for about a year now and have had the MSD for about three, no problems with the ECU, turbo, or exhaust...However I'm not saying that this doesn't cause excessive strain on the turbine wheel and exhaust cause it deffinitly does just saying that i've been fortunate to...

The ECU will need to be involved in the way i have it setup now, however as mentioned above(by someone else) the best solution as of now to keep the ECU from cycling between modes is to install a switch, to disengage the timing ground wire to the aftermarket relay.Yes it is to help keep a...

Ah yes thanks thats what i meant, slipped through the proofreading cracks, thanks

It can be done. If you retard cylinder ignition systematically, while also using correct timing to keep the car at idle speed you can get the certain cylinders to ignite with the exhaust valves open, thus creating a very large rush of unused power to spool the turbo. Also you may inject...

I've had this on my car for the past year or so, and thought i'd share it with everyone else, to help some folks out or to have people point out the flaws in it.First off my 91 TSi AWD has: Completely stock longblockExhaust: TEC td05 18g ported ported 1g o2 ported 2g exhaust...

I used a automatic 4 bolt in my 91 manual....HOWEVER i did swap the pinion gears from my 3 bolt into the 4 bolt. Works great, so if you can find a auto 4-bolt for cheaper like i did, just swap the gears and maybe save yourself $$$.Also there are four different diffs. Manual and Automatic...

The ISC motor has a harness with a connecter on it that is different as well, i believe?

What do you mean by mix them? The one on the right is a 450cc stock turbo injector with a missing/broken insulator, can you repost with a clearer question of what you are trying to get answered?

I run 660cc denso's and have noticed the same thing, I also thought it might have been the fuel pump. my FP drops from 30psi to 0 in about a minute. What I have for a fuel system is a walbro 255lph HP, 6- lines tank to factory return, K&N fuel filter, westach FP gauge, denso 660cc inj. and...

Put the car in 1st gear and push the clutch in and then start it. If it moves then it is most likely something hydrolic, like a slave or master cylinder, check the clutch fluid and make sure it didn't dip to low and allow air in the lines.What I would check in this order are: 1. Bleed...

The first is of the turbo with the wastegate actuator arm attached. See on the right side of the turbo(exhaust housing) where the arm connects to, see if that is still connected to the turbo on your car, and that it is in the same position also.The second picture is of a couple wastegate...

with the open downpipe you are probably overrunning the wastegate. It doesn't do it city driving because when you are doing longer highway runs the motor is underload for a longer period because of the longer gears. what is with the quotes around the "boost gauge" what kind of gauge is it?

Did you check to make sure the grounds are still attached though? and the wires not broken? Do the buttons light up but not the screen?

your vacuum should be down near 18 in/hg if not 20 at that low of elevation. Check your boost gauge vacuum line and make sure the line isn't kinked, what line did you tap into for the boost gauge, and how did you tap it?have you ever done a compression test on the motor since the head was...

Look at the vfaqs, under electrical, to see how to pull codes with a voltmeter. Boost is controlled mechanically so the CEL you are getting is not causing this, however you should pull the code anyway to see what it is.The wategate actuator arm is under the lower heat shield and is...

The ECU retains previous check engine lights, so just pull it with a voltmeter and look it up in the manual.or check this out-http://www.vfaq.com/mods/wayback/BradBauer/electrical/code.html

Is the Wastegate actuator arm attached to the wastegate? You should pull the CEL with a voltmeter and look it up in the manual, and what is the vacuum at idle?

If the buttons still light up but the screen doesn't then one of your grounds is not connected, but if both aren't on then the power wire is disconnected. Did you solder the connections or just use wire tap quick connects? Did the check engine light come on at the same time?I had the same...

True you can tune with Map instead of TPS, But for the $1K+ it would cost for this setup is not really worth it when you can shell out a couple hundred more for SAFM.

Have you checked the actual voltage while driving around? Was it a mitsu alternator or was a Autozone/checker alternator? I've had Autozone alternators die out faster then 2 months before. If the voltage regulator was going out the headlights would start to flicker. I would check the voltage...

Is it a turbo 3kgt mas or NT?If it is a turbo mas then it is the exact same as a 2g turbo.

The only thing grounding out the wire to check base timing does is disable the ecu from advancing timing correct?I would imagine it to be possible to hook this to my msd stutter box relay and have it keep base timig while on the box? Instead of advancing the timing relative to rpm.I...

From what you said in your first post I figured that it was more then just the recirc tube, but the info in your second post points to the recirc tube, toss it on and get back to us with resultsGood Luck

Does it ever leak while under any boost?

Check timing to see if the timing marks are lined up correctly. What happened when it died? Where you driving it hard, or just cruising.If timing did slip then it would more then likely have 0 accross the board but the only way to know for sure is to do a leakdown test or pull the head...

Plugs and wires would be the first thing I'd check.I'd check plugs first as they are dirt cheap, if you have a wire brush clean off the carbon deposits then (re)gap them at .028 and try it.If that doesn't work get new plugs and try those with a .028 gap.If still no avail then try a...

Water disapates heat better then coolant, but coolant has a higher boiling point than water. Coolant also lubes seals inside the cooling system, such as the waterpump seals and o-rings.100% water cools better then a 50/50 mix but is limited to its 212*F boiling point, In Colorado I always...

Putting the recirc tube on will not help with the problem if it is not holding boost above 5k rpm.All stock BOV's leak a little at idle.Where is your BOV vacuum line tapped into?Have you tried the 2g BOV at stock boost to see if it still happens?How many psi are you running...

What size cc injectors was the viper running as well as how many cc of water were being injected?I do agree with NOSlaser on the fact that you can't really cool the intake temp any more than nitrous is able to. Nitrous I believe is injected at -176* F.I do however believe water...

A barametric pressure sensor and Map sensor are two different things. I know it is in my mas barametric pressure sensor reads static atmosphere pressure not boost

Take the vin and registration to a Mitsu/Eagle/Plymouth dealership and they should be able to cut you one. Only the dealer of the make of car can do it. If you have a Talon take it to a chrysler dealership, eclipse take to mitsu, etc...

It looks like a 2g 95-96 because of the obd-2 and crank angle sensor on the block

"So now that I have a aftermarket boost guage, if I drive up to 5,000 feet it will read 8.1 psi" quote] No, the factory wastegate wont allow full boost to be that low and the atmospheric pressure will drop, not the pressured air out of the turbo. your vacuum in in/mercury*2 will defenitly...

What car is that diagram of??

Yes but you forgot to take in account that if you are pushing 1 bar(14.7psi) of boost then you are running a total of 2 bar(29.4psi) in absolute pressure at sea level. The higher in elevation the lower the absolute pressure ex: ~5000 FASL (feet above Sea level) absolute atmo. pressure ~11.8...

I don't know what you are saying are you asking a question or stating something?No DSM's have MAP sensors. They all use karmen sensors, rpm, and o2's to define how much fuel to inject. I don't no if the barometric pressure sensors are used for fuel delievry or timing? The ecu has...

He kind of has it right the Ecu does adjust for the octane used, but dsm's have no Manifold pressure sensor or MAP sensor. It adjusts over time, based on feed back from the o2 sensor to change the high/mid/low fuel trims.Also when the engine detotonates it will retard ignition timing to...

I need to remove the cap on the front case behind the oil pump gears because I'm leaking oil past the threads. It needs a specialty tool to take off the plug. The plug is the one directly above the oil pump sproket. You can't order specialty tools from the dealership so I think a may be SOL...

1. no just keeps turning and turning 2. No 3. yes: have fuel pressure and fuel on spark plugs when taken out 4. yes: sparks at TDC via Timing light

Yes I do have an egr blockoff plate. This does not appear to be the case however, even so I can not start the car. I did this about six monthes ago to attempt to ride the je's of some of the carbon deposits fromrunning rich, i used an 1/8th of a can of MCCC(Mopar Combustion Chamber Cleaner)...

Thats a good call on the cams, I'll swap in a the pair from my spare head. I din't even think about that possibility. if something was't letting air out of the engine(just in) however that wouldn't have the ill effect of low comp, correct?The comp. tester went up with the wet test though...

I guess the only sure way to tell is to get a leak down test?

I fear that it may be rings aswell but it is just odd that compression dropped all at once and it is exactaly the same dry comp. in each cylinder.The car pulled very strong w/ no detonation, had plenty of low end torque and then boom compression went from mid-high hundereds to 75 psi. I...
