So I'm wondering if there are downsides to adjusting camber with LCA instead of the conventional uppers, on a drag car. #1 it pulls the wheel in at the bottom and doesn't push it out at the too near the sheet metal where a wide tyre can rub. #2 I don't have to deal with the rusted out eccentric...

Wondering if I need to add a relay to run a vacuum pump (audi) on my auto. Right now i have the 12v from brake switch going to pump and it sounds healthy, not blowing fuses. It's been like this for a while but I don't want to burn out the switch over time if it's not rated to handle that kinda load.

Theres a weird buzzing from the cluster or behind it right around 2000rpm thats only there for about 100rpmSwitched clusters still does it. All electrical works, windows don't get as much juice as they should as they go up reallly slow and i cleaned the tracks. The power window relay and...

I'd like to monitor the pump pressure and clutch pressures by installing a pressure sensor in the test ports on the exterior of the trans, I didn't see anything about these ports in the service manuals I'm using, anyone know what size they are and what they do? Doesn't look like 1/8BSPT.. From...

Can a precision 1g converter be had for a 6 bolt/1g trans and yes I know there's a kit from Kiggly and JB Design but i don't want to convert to 2g trans as I have 2 1g trans and 1 is freshly built.I've ran into some threads from a long time ago where people have used precision converters...

My lower valvebody separator plate has a worn/ovaled hole where the pic says "1/4"steel checkball". I can't find any to buy and all my spares also have worn holes.Does anyone know where to buy one(the small plate)? Or if there's a fix such as drilling it out larger to make it round again? What...

So why does 1st use different combination of clutches between the D and L position according to this chart? Is it even the same gear then? Looks like both use rear clutch but the one way clutch(sprag in gearset) gets switched for Low-Reverse clutch in L position.Does the low-reverse clutch...

Ring gear is out of an early 92 AWD auto, the left half of each tooth tip is machined different than the right half. Every single one. There's actually a step down about 0.05mm where it transitions the smoother to rougher serration. Any ideas if this is normal or a Mitsu f***up, why I'm...

Will 2001 Mustang Cobra wheels fit on a 1G with 245/45/17 tires on? I know the tire isn't an issue as I have them on right now but on a 6.5" rim.:coy:I don't know the offset on the cobra wheels but I know they're 114.3 and 8" wide.

I got my AWD tranny with a welded center diff only hooked up to the front axles i'm just wondering if it can handle a decent amount of power like the FWD trannys? Is it prone to the common problem of the FWD tranny where the roll pin on the front diff cross shaft breaks? It seems to me that...

Ok, so I've read a few topics on here about this but it keeps going back and forth wether 15" wheels fit the AWD brakes or not...can anyone chime in on this? Thanks.

I've relocated my battery to the rear of the hatch and ran 2 gauge wires for the power wires, and 0 gauge for the short ground which is at the most 2' and it grounds right to the hatch floor through one of the bolts that was already there. Ever since I've done this I'm getting ignition breakup...

I'm looking at the turbine side options for the SC61 turbo and it comes in 3 sizes T350-52 (630HP), T04-69 (650HP), T04-76 P-Trim (680HP). Are these the same as the stage 3, 5 and P trim I see people reffer to as? My goal is 600AWHP on a built 2.4 and I have all the supporting mods to do...

I can get my hands on a OEM Bentley GT40R, the ones they used before going to the twin turbo setup. I can't find any specs on these units, just wondering how they differ from the standard Garrett units especially the flanges, A/R as I'm guessing the wheels specs should be same as a standard GT40R.

Would it be ok to swap an intermediate shaft from a '92 trans to a '90? I need to do this to be able to fit the larger diameter 2nd gear from the '92+ gearsets. The only reason I can think of why it might not work is because of the center diff lower housing is different on the '90's, although...

I was filing the rings down for the proper endgap and I got one of the top rings to .027" on accident. I'm reading that running such an endgap is ok for motors planning to run about 500 flywheel horsepower and that's what I'm planning on. This is according to a calculation that ross provides...

I just purchased the FP dual valve springs and they need to be shimmed for the FP3x cams I got to 1.475"-1.485". I've never had to shim valve springs before so I'm not sure what measuring tool I need to use on our heads and exactly how you would measure (from what point to what point). I'd...

I've noticed that the MT 22 spline transfer cases from the 90's are about 7-8lb lighter than the 23 splines. It didn't make sense at first because they both have the exact same exterior dimensions but I confirmed it on the scale. Is there a reason for this other than heavier metals used in the...

Well a few things are noisier other than the expected wheel skipping in tight turns. For one my front axles act like their coming apart upon low speed turns as if I had really bad CV joints, but they never made noise before the welding. I am not too worried about that as it only does it at low...

Is there a comprehensive SMIM thread with dyno/airflow testing such as the one that used to be on the NABR forums or does that one still exist? All my search efforts turned out fruitless...

Well I have a coolant overflow problem where it pushes the coolant out of the overflow once I get it into boost so I did a leakdown to check the headgasket. I also did a compression test and the numbers were 130-80-160-190 on 9:1cr pistons. The only piston that has proper compression is #4...

I recently installed an XTD stage 3 clutch and their lightweight flywheel and I did the usual pivot ball shim. This is not my car, and I recommended against this ebay clutch and more importantly the flywheel as DSMs seem to be very particular about the correct step height/dimensions of the...

I just installed a used engine in a car that has been sitting for 3+ years. Fuel pump was full of rust as well as the inside of the gas tank. I replaced the pump as the old one was dead. It had some gas inside it, maybe 1/4 tank, but I didn't drain it and now I wish I did I simply put in...

Will shocks from an AWD fit a FWD 1G? The only info I can find is about the spring rates being different.

I am currently working with a local clutch shop to have kevlar facing done to my worn street disc. The material they use is proven on much more demanding applications such as transport trucks, buses, and other heavy duty applications where lots of torque and heat is generated. I've worn down a...

There are many writeups on setting up FWD suspensions but I have only found bits and pieces on setting up the optimal AWD suspension. I am guessing we're going to adapt both concepts from the FWD world and the RWD world as our cars have traction on all four wheels.First I would like to...

I am having a hard time removing 5th gear as there is not enough surface to grab onto it with my puller. Is there a special puller or another tool I can use other than screwdrivers as I don't want to chip the gear. Also do I have to grab the gear itself and slide the whole synchro assembly off...

I'm wondering why there's a difference in the pedal feel between mine and my friend's DSM both equipped with a 2600. His is a 92 AWD and mine a 90AWD, we both have SS clutch lines but his pedal feels about half as heavy as mine. Is there a difference between the clutch master/slave cylinders...

Hi, I did a search on this topic already and so far I'm not really sure about the benefits of upgrading the proportioning valve from a 90AWD to a later model AWD such as 93 and on. From what I see this will decrease the front clamping power but if I upgraded the front brakes to the 2 piston...

Like the title says, I just noticed a small cone shaped hole in the top of my brand new Wiseco pistons. They are individual pistons right from Wiseco as I needed 2 replacements. I don't have a picture, but it looks somethiing like this: -v- basically. It is very small and it's on both of my...

I'm going to be throwing in new Wiseco XX rings and I will be honing (de-glazing) the cylinder walls with a drill and a traditional surfacing hone with the 3 spring loaded stones. My question is if this finish that I will get will be fine enough? The tool says it uses 220 grit stones and there...

Ok, to make a long story short I had the block bored 20thou and I got the matching Wiseco pistons for this bore in the 9:1cr. I had the whole job done of boring, honing, and piston/ring mounting and then piston/rods installed in the block done by a local machine shop and he checked all the...

Hi, I have purchased a pair of front 2nd gen AWD brakes for my '90 AWD not knowing the lines would be different. I haven't tried to bolt these up yet, but they came with the mounting brackets so it should be no problem. Now the problem is these new calipers accept banjo fittings and my stock...

Has anyone had problems keeping low boost with this turbo? I am having a very difficult time keeping this turbo at low boost above 5200 rpm. My exhaust consists of the Evo3 exh mani, Joe P. 2.5" tubular O2 w/external dump wastegate, 2.5" DP, 2.5" cutout mounted on off-road pipe, and stock...

I just had a engine builder install Wiseco 9:1 .020" overzised pistons/rings and I'm getting weird compression numbers. They are 145-105-175-165 after 800km. I did a wet test and leakdown test to find the root of the problem. It seems to be the rings not sealing properly since the cr goes up...
