Big/thicker intercoolers do restrict airflow, but any overheating problems are usually due to inadequate fan flow when the car is still/at low speed. As long as the radiator is not blocked, airflow is usually fine once you get going

If you’re pushing or even towing with all four wheels on the ground (like with a tow strap) there’s nothing to worry about. It’s basically the same as coasting downhill in neutral. Our F/R bias is 1:1, unlike some modern AWD cars that have a slight speed difference between axles and an...

Nice - what front grille is that, or is it also a one-off?

Actually, it won't - the deposits form on the tops of the intake valves, not the side facing the combustion chamber. The long term problem (tens of thousands of miles of operation) is that the buildup can get to a point where it impedes airflow. Additionally, with hydrocarbons, the heavier the...

The FP3 cam is almost, but not quite identical to the FP2 (same lift, same durations, but the intake cam is advanced 5.5 degrees. The ramp on the FP3 is subtly different, but installing and degreeing FP2's and then advancing the intake cam will produce very similar results. Or as mentioned...

After doing looking around a bit at some more DoE and ethanol industry literature, the consensus seems to be that the goo is caused by not just the factors I mentioned above no detergents in the ethanol portion of the blend, and lower quality gasoline with a lot of heavy "gum" hydrocarbons, but...

Are you getting your e85 from a station that sells premix, or a blender pump? (one that mixes ethanol with gas from the main station tanks)? What you might be encountering is due to the fact that premixed e85 is often mixed using very low grade gasoline (85 octane or lower - the ethanol largely...

Try a place that sells A/C kits for Hot Rods. The 50-60's bodystyles have really small radiator grilles.Example

Galant VR-4 RS to EVO IV are 510cc yellow-topEvo V and onward are 560cc

Someone might also point out that the factory oil is either 10W30 or 5W30. Most people seeing pressure problems are running at least 10W40, or more likely, 20W50 or thicker oil (Like anyone foolish enough to run straight SAE 50 "race" oil in an engine not designed for it). An oil that is too...

Autometer makes a 3-gauge panel using 1-1/2" electric gauges, but it's fixed for oil pressure, voltage and water temperature.You can purchase them together, or individually if you look around at places like Jegs. Google "Autogage 2391" for the combo and "Autogage 2354" "Autogage 2355" and...

The reason people remove them is that the FIAV can go bad. It is normally open and the warm coolant melts wax inside it, which expands and closes the valve. When it goes bad, the wax leaks and never manages to close the air valve.The net result is a higher idle speed when cold, dropping down...

From looking at some documentation (I haven't compared the 3000GT VR4 axles directly, just the 3000GT knuckles I have in my garage), if the actual axle bar spline is the same on the outer CV (BJ), you could put the 3000GT CV on the Galant axle bar.It seems that it should be possible. Worst...

The 3000GT hub uses a hub and bearing that are a single unit, so the hubs are pretty much incompatible.There's no such thing as "almost bolt-on" The evo calipers will still require some sort of interface. Using adapter brackets really isn't a big deal compared to all of the other things you...

Bought a transmission, and he was willing to drive almost an hour each way to meet me partway - great to deal with.

The balljoints, and struts are bolt-on. The steering tie rods are bolt-on, but have slightly different geometry.The hub though, uses a different bearing design with a bolt-in retainer (instead of press-in) and the knuckle is physically beefier. The main problem adapting them is that the axle...

The EPS computer controls the solenoid valve to release pressure based on vehicle speed, so it acts like a true "speed sensitive" power steering instead of just "RPM sensitive" like the normal system. The "sport" button just causes the pressure to drop off more rapidly with speed.The...

Some galant GSR's came with it - very cool system that changes damping for cornering, acceleration and braking, and adjusts ride height based on speed, backing up and opening the door, but its major failing is that the hydraulic pump can only stand up to about 15 minutes of "spirited" driving...

Do you have an aftermarket downpipe and a stock or 2G style O2 sensor housing? Check the gasket between the DP and the O2 sensor housing - There isn't much sealing area with some downpipes, and if you've ever whacked the exhaust over a speed bump, or especially backing out over a curb, there's a...

Also keep in mind that you can get away with a surprising amount of boost on the stock pistons because of the lower CR (7.8:1) You should be fine in the low-mid 20's with a small turbo. Anything higher will probably require a very large intercooler to bring the heat down (or water injection). A...

The measurements you took on that intake cam work out to somewhere between .376 and .393 total valve lift, depending on whose "stock" lift measurements you use (published on various sites like BC and Crower cams). The .393" lift would match an HKS 264 intake cam, but the markings don't look much...

The absolute limit is dictated either by:A) Intake air hot enough to cause detonation unless timing is severely retarded. i.e. by increasing boost and flow, you actually lose power from pulling timingorB) The intake air is getting hot and turbo efficiency drops to the point that the...

What you have there is basically what catch cans try to imitate, i.e. it's just a really high-quality catch can like the type used in airplanes. Aircraft Spruce sells several types: clickIn the catch can, the mesh stuff basically performs the same function as the air-oil separator, which is...

If you'll notice that the motor mounts are off-center to the top, but when the engine is installed, the weight of the engine causes it to sag approximately to the center of the mount. Shouldn't be a problem.

You've pretty much got the right idea - bring it back to the front axles or farther if you can. Clevis pins with cotter pins to the subframe is probably the way to go. Make sure they are a good fit and won't rattle though.You shouldn't need a full semicircle, but definitely generously rounded...

Judging by the fact the car is still "driveable", the pressure on the front brakes is pretty light, more like dragging brakes.If it were a bad master with a piston not retracting, the pedal would either be really soft in the initial travel, and/or you would be having problems with a diagonal...

The back of my napkin says that on average, the stock clutch (1650 lb plate) with a typical 225mm organic disc should be able to stand around 270 ft-lbs of engine torque. The practical number is probably a bit less, since that doesn't include any other factors like reduction due to heat or a...

The v2 "chip" for 1G's/GVR4 is a full daughterboard. The v3 (ECMLink) chip is a single red chip with no extra board that should have the same pins and fit the same socket as your keydiver chip.Which version did you buy?Quoting belize1334: This may be a difference between v2 and v3 which (as...

Two tips:Give it a good 2-3 days (or more) and spray the bolt 2-3 times a day with PB blaster, or another rust dissolver/penetrating oil. If it still won't come off, give it some more. It definitely makes a difference. You can also use heat if you're not patient.The second only applies to...

Not quite.Helical gears themselves can actually take higher loads and higher speeds(i.e. transfer more power) before they will break, since the load is spread out over more area, and they engage more gradually (less shock loading).The caveat is that yes, they produce side-loads on the...

I finally figured out the source of this rumor when I picked up a copy of "Motor Fan Illustrated" with info on the Evo X. There's a little chart with "history" of the SAWC, and it includes *two* "Galant VR-4" entries - one in 1988 showing the drivetrain with a VCU, and one in 1992 that features...

Shimming out the transmission doesn't sound like such a hot idea - problems you might have are water and road grime getting into the bellhousing and contaminating the clutch, and you might not fully engage the clutch disc. Also, you might not get enough engagement on the dowel pins that take up...

Here's a tip I just discovered the other day on removing rusted underbody and exhaust nuts, especially in places where you can risk stripping or snapping off a stud:After applying PB Blaster liberally and letting it sit (twice a day for a couple days if it's really bad), clean up the bolt...

Try JNZ Tuning?

The Evo 8 uses a different style balljoint than ours (clamped straight shank instead of tapered seat). What you're looking for is a set of balljoints with a longer shank than the stock ones. The 3000GT control arms, balljoints and hubs use identical mounting geometry to ours - the hubs are just...

The actual starter is the same. Though, in addition to the flywheel, the FWD bellhousing is smaller, and it positions the starter in the right place for the smaller FWD flywheel.

If you're looking for junkyard stuff or oem parts, the "forward facing" housings come off of RWD applications (like 4G64 equipped pickups) FFWD has them as well

The 2G pump is basically identical internally to the older version. The flow control valve is actually a 3-stage setup. It has two ranges where it decreases flow (sharply between 700-1000 to compensate for weak pump flow at low RPM and at a slower rate at 1000-3000). And the final stage above...

Just noticed this sale on FP's website: FP68HTA

Okay, so after second guessing myself, I finally decided to sit down and work out the force balance to figure out what the heck is going on in the planetary differential.The answer I came up with, surprisingly (to me), is that the differential puts 35% of the torque to the front and 65% of...

If you use the straight end of a hooked crowbar and angle it across the front of the housing in a way that prevents if from slipping sideways, and keeps it lined up straight (a block of wood as a fulcrum might help), and then just bop the bar on the hook (towards the axle cup, not just a prying...

The only thing I can think of is that if you jack all 4 wheels off the ground, and run the car in gear with the wheels completely unloaded, the center diff will try to spin the rear wheels twice as fast as the front (if it's a 33/65 split). (the 50/50 torque split is only stable when the wheels...

They literally mean "a little more lobe" in all directions (lift, duration at 0.050", ramp rate, etc), but with similar lobe centerlines and overlap.If you look at FP's website, they have graphs at the bottom showing the actual lobe profile compared to the stock cams

The only thing that's different is the bracket that attaches to the block. The front and rear Avid mounts are only the part that bolts to the subframe. And only the front mount is different between 1G AWD's and the VR-4. They'll work fine as long as you use the correct front bracket. I guess it...

Try Road Race Engineering. They carry the porterfield R-4S pads, and are also familiar enough with VR-4's to know which parts you're looking for.Plain rotors work just fine as long as they are decent quality (Rock Auto carries some decent brands for cheap). Unless you're using race...

Allow me to summarize:What you're effectively doing by compressing air to 25psi and then restricting it to 10psi is running the engine at part throttle, all of the time.

I was wondering when they'd come out with a DSM version of that. That's the compressor wheel they've been selling for a while for Subarus. I believe it's a mirror image of the 68mm wheel that was developed for the Evo FP White. It's probably being sold with a TD05H since they're trying to market...

This is one of the best pieces of advice you can pay attention to. I set out to start rebuilding a motor in the way I wanted to, replacing everything I thought was worn with shiny new OEM parts, and ended up with a JNZ order for over $1500 in just stuff like gaskets, water pump, bolts, etc...

There are a couple problems, and you nailed one of them already.When you compress gas, in addition to temperature changes, you are making it more dense, and vice versa when you expand it. The goal here is to increase the mass of air that reaches the cylinders. In placing a restriction after...

Find someone you know who has AAA for the tow. Alternately, if you know someone with a pickup and hitch, U-Haul has dolly or flatbed car trailers for $40-50 a day. (They'll also rent trucks, but it costs more)
