Ppl have made over 600 on the stocker...I've personally witnessed almost 750awhp on a 1g TB

If you were concerned with the BOV being sufficient why not just run one larger more efficient BOV?

exactly. They didn't bother with the 6 bolt as the larger diameter of the studs, holes, threads didn't warrant that style of stud. The ones in the 6 bolt haven't met their limits yet, at least not that I (or they) know of!

Yea there is definitely something fishy going on. Are you feeding it from the OFH or the head?It's possible that the pressure relief valve in the OFH is gummed up or stuck, causing oil pressure to get out of control above 6000rpm. It's happened before.

@ 2 bar i'd use their H11 head studs. I have them on a built engine ready to push 45-50psi with a borg, and from my experience as well as others the MAP h11's are beast and worth the investment

The ECU does send a signal to kick on the relay for the fuel pump, but to be honest, you're on a 420a, and that's completely out of my range of expertise lol.If it was a 4G i'd know more, but idk shit about the 420 ecu or wiring, so i'll let the NA gurus chime in

You could also feed from the head like these ^ guys lol...If you go that route, make sure you plug the filter housing outlet with a bolt that is BSPT (british standard), not NPT. I can't tell how you many people i've listened to wonder why their filter housing cracked or is leaking when they...

which is why you should put it on a JMF Drag manifold, works beautifully :o)(except its so damn big and sits so low on that SMIM that you need to eliminate heater core hoses and all kinds of other sh*t)

Cutting corners here is the last place you want to. Besides, if you really want to you can pull a block in a couple hours!

NP...It will definitely help in the higher rpm range, especially when at full temp and the oil is thinner. Brought my pressure down about 30psi

regardless of its location, if you're blowing fuses that fast I would once over all of them and check if anything else blew. Clearly there was some sort of short/power draw causing this.

+1 for adjusting the greddy, but that may or may not solve your problem. If the bov is leaking from the seal, adjusting it will do nothing. It might make a minor difference, but it will still need to be fixed.

If it fires from 1 wire on a coil, it will fire from the other. The transistor, as well as all other ignition electronics are before the coils, so they will not interfere once the current reaches the coil, only before. The coil fires both wires/plugs at the same time, hence "waste spark"...

Agreed, I'm pretty sure they can not be installed upside down due to holes being offset...

FYI most aftermarket fuel pumps, especially higher flow/external ones do make quite a bit of noise. The higher flow ones are much louder than walbros.

A valve being bent will not throw off the timing marks on the crank, cam gears, etc., so that is not your problem.What exactly is going on that you can't time it correctly?

Use a ported OFH to reduce the oil pressure top end some. It is a general consensus that thrust bearing turbos do NOT need a restrictor, as long as your oil pressure isn't getting out of control high.There is actually some information supporting that certain inline oil filters and...

sounds to me like your getting some compressor surge, and the black puffs are from the fuel mixture. A vacuum/boost leak will affect you in all gears.

just resolder them then...I have an oil pressure gauge, but i still have the factory gauge cluster ones hooked up anyway, it wont hurt.

why did the plugs get "ripped off" to begin with? they shouldn't contact the ground. You need to review your installation...You could hard wire the sensor, but they are replaceable because they burn out, so you'll need to cut the wires when you put a new one in eventually (or somebody will)...

The wires go to the sending unit on your oil filter housing. It is on the bottom right of your engine, underneath the alternator. I'm not sure which wire color is what anymore, I haven't had a dsm with factory wiring in a while, but there is a thread on here with complete engine bay wiring...

If you mean your swapping your ECU for a -95 eprom to chip it (link or whatever) then no, the transmission does not matter. Just make sure it is in fact an eprom if thats why you're going for, not all 95's are.I'd also take a look at the board (pop the four screws out and take the metal...

What makes you think its the alternator. Have you checked the voltage of the charging circuit? have you eliminated other variables? Many things can cause a misfire

if it's any consolation the more ethanol there is in your fuel (e85 for example), the more it will change the color of exhuast smoke (from a rich mixture). It wont be the same color as the typical black puff from rich mixture with straight petroleum fuel.What is your engine management? If...

You are not going to be able to swap a 420a into a 4g....well you could but it would be completely assinine.You should be looking for a motor from any turbo dsm. You can use the older style engines from the 1G DSM's called 6 bolts, or any 7 bolt (newer 1G and 2G). The "benefits" are that the...

he's right... that'd be #1 on my list!

Idk about a "test" per say, but it shouldn't be that hard to locate where the smoke is coming from.How much is the cat smoking? And is it smoking from where it couples to the exhaust pipes on both sides?

There are many things that could cause smoke like this...-As for the back of the block, you said it isn't coolant, but there IS a freeze plug back there. Worth checking with the mileage on the car.-Your head gasket could be blown. You said the turbo was blown, yet whiteish smoke is still...

are you blowing the fusible link for the alternator? It could possibly be shorting somewhere, or the regulator fried.It is oem correct?

yes i am using a 2g tps, same setup i used before i switched out my intake manifold. I ran a boost leak test, pressurized it pretty high and it didn't seem to have any significant leaks, but i will try again i suppose....I dont think the idle "surge" is from the coolant temp settings. It...

Ok let me start off by saying i'm no newbie with this, but i couldn't figure this problem out with the time i had with my car. I am an active duty marine, and need to figure this out before i go home so i can fix it...I just recently finished a massive amount of work on my 97 tsi awd, which...
