Hi all,I have something of a weird issue with my fuel pump rewire. I rewired my 255 Walbro several years back and was working great, but one morning, the pump doesn't turn on anymore (using DSMLink).With the fuel pump turned on from DSMLink, I checked the voltage from my 12v wire going...
This is my custom v-band o2/downpipe for the Holset's non-wastegated 12cm^2 turbine housing. I performed all the cutting and fitting, taped it together, then took it to my local welder to finish the job. Boy does he do good work :applause: Not the funnest part of the build, but, I am very proud...
To quench this 2.3's thirst for E85, I picked up a set of FIC high-Z 1680cc injectors. The idle on these should be near stock!My hx35 oil drain setup is shown here. I fitted a pipe to a drain flange, had an EMT conduit sweep welded to the oil pan, and connected them both with Vibrant...
After 3-4 years of driving around with an aging stock 2.0L with less than stellar compression numbers, I finally gathered up the time, funds, and materials to tackle a rebuild. I wanted torque, lots of it, and this is how it came together:Here is the shortblock assembled.All clearances...
Just adding finishing touches to my engine build and hooking everything back up. I've been running E85 for several years now and will continue to do so. However, I've never had my old motor start up at first crank (cold start) running e85, which is fairly important on the first startup of a...
Hi,Does anybody have the part number for the cam gear bolts? I looked up CAPS through MachV's website and got 11-230-0385p but I don't have CAPS on the computer I'm using right now for the part number. Anybody can help me look it up or have a thread-pitch-length?
The idea of this build is a very quick spooling turbo with a big emphasis on low-end torque, with a suspension setup that picks up some of the slack left by the understeering stock setup. I plan to take this to autocross events and the drag strip maybe once every two weeks but its duties will be...
Ever since Koni decided to discontinue the 1g AWD rear shocks, the 1g AWD guys have been forced to run Koni fronts with an oddball setup in the back (KYB AGX, Illuminas, etc.). Because the quality and adjustability of Konis, they are among the better shocks offered for the money. Here is a...
Hi guys,Im looking to find these part numbers for the rear strut assembly of a 1g awd. In the diagram below, theyre labeled as numbers 6), 8), and 10).I am trying to see if these parts are interchangeable between a 1g awd and 2g rears. I was able to find the part numbers for the 2g...
I posted this question in another DSM forum but haven't gotten many replies so I figured maybe a site which sees more traffic such as this one would yield some more response, opinions, thoughts, etc.There have been a couple questions on my mind that I just can't figure out. I noticed there...
I remember there was a thread made recently that had a list of common things to remember to do when rebuilding the motor, such as not applying lube to both sides of bearings, using a paint pen to mark torqued fasteners, etc. but I cannot seem to find it. Any of you guys subscribed to it or know...
Here's a quick tool I made to estimate the injector size you'll need for a particular horsepower goal. This is based off the valid approximation that the engine makes 9.5hp per lb/min of airflow. Simply enter the fuel stoichiometric ratio, density (I've provided values for common fuels), desired...
How does a turbo with a small turbine housing choke up an engine in the high RPMs when matched with a sufficiently large wastegate? I understand that choke is the event where exhaust backpressure becomes too high and volumetric efficiency is lost, but with a wastegate that is large enough...
There is a thread in the Turbo-Tech Section on the effects of using different sized intercooler piping, and what I learned from reading that is bigger is not always better and that the desired size is to have it as small as possible while keeping the velocity < 0.4 mach (where flow becomes...
I purchased 3000gt SL dual piston brakes for my 91 talon awhile ago and just recently got to installing them. I bought 94 awd talon rotors to go with the dual-pot calipers and the swap went without much snags until the entire assembly was put back together, brake system bled, and wheel lugs...
I'm wondering what kind of piston to wall clearance I should aim for using the Mahle pistons in 85.5mm bore size. These are the 2.3L stroker pistons with 9:1 cr. I called the sport compact tech at Mahle and he recommended .0016"-.0024" but that seems a little tight to me, even for a low...

Hey guys,My first alternator has bit the dust, and I assume it's because of the extra heat from the new setup. Anyway, I wiggle my way around and inch out nuts and bolts trying to pull the alternator. Every fastener has been removed except for the pivot bolt. The nut came off easy, but I'm...
I recently installed an AFPR, sending/return lines, injectors, and a walbro 255. Also just rewired the pump.When I turn the key to acc., I don't hear the pump prime for several seconds. As a result, it takes a couple cranks for the fuel pump to rebuild pressure in the lines before the car...
This weekend, I tried installing a walbro 255. Everything went smoothly until I was assembling the new pump onto the assembly, screwing down the nut that holds the lug connector of the power wire to the top of the assembly. Well, I must have overtorqued it, the stud broke off and I was left with...
What color is the wire for the power that goes to the radio on the stock harness? I thought it would be the black with white stripe but it isn't among the wires. Any help is appreciated, thanks!
I understand the proper way to set up the oil catchcan off the valve cover breather hose is with a sealed catchcan with one line going to the valve cover and the other to the intake to route back metered air.BUT, if you have a GM maf in blowthru setup, routing that air back to the intake...
From cylinder 1-4: 150, 150, 120, 80.
The car still runs and drives fine, but loses power after 4000rpm. Can worn rings cause compression to drop so much? There are no coolant or oil leaks, but I think the head gasket is blown between cylinders 3 and 4. What other causes could there be? How...
I was trying to tune my airflow using DSMLink this afternoon, I was at about 4000rpm when a loud rattling sound like there are a dozen marbles in my cylinders suddenly comes out of the engine bay. I get off the throttle and slowly cruise it back home (30 secs away) at around 1000rpms, rattling...
My ecu is throwing code 14, and my car is idle surging. Something is wrong with my TPS, so how can I go about fixing it? Do I need to buy a new one? I read on here that TPS's on our cars need to be electronically configured manually, meaning I should take it to a dealership.. And does a...
I was gonna install my ss oil feedline for my turbo to the oil filter today. When i go down under the car and try to remove the allen plug, i had no luck. Even stuck a couple extensions on the allen wrench and took a hammer to it...i searched the forums, some people say use a torch? wouldn't...
when i bought my car, the owner said there was a boost leak that he couldn't fix, so i bought it thinking i could fix it later. there was a check engine light and i was told it was just for emissions.i drove the car around like a granny but whenever i did step on the throttle, the car would...
hey guys, i just recently registered but i've been reading this forum for quite a while and theres a ton of useful info out there! that being said, id like to ask some of the more experienced tuners if anyone has done a M/T swap into a stock A/T 91 AWD Tsi?could someone possibly provide a list...
