Fluidyne Aluminum Radiators

This thicker core radiator is a significant cooling upgrade for those cars that are running on the edge. These are a direct bolt in upgrade radiator. The stock fans bolt right up.

1G Fluidyne (Turbo and NT) $350
2G Fluidyne (Turbo and NT) $350

SPAL Slim Radiator fans

SPAL makes some of the nicest fans we've seen. They are much thinner than stock and flow very well. We carry a variety of sizes and flow rates. You will need to splice in the wiring connector. Brackets are easily made with a strip of aluminum to bolt to the stock fan mounting location or the body.

"Push" means that the fan is in front of the radiator, pushing the air through. "Pull" means that the fan mounts on the motor side of the radiator and it pulls the air through the radiator. You want the thickest and highest flowing fan that you can fit in there.

RRE Billet Spark Plug Wire Cover

We were never happy with all the cute plug wire covers available. We had always preferred to just leave the cover off to let any heat out. Our CNC machined thick aluminum cover is vented to let out heat but still give a nice custom look. Stainless steel fasteners are included. It is available in the raw CNC finish (shown) or highly polished.

Polished Plug Wire Cover	$94

Crank Case Breather / Catch Can

$54

The vent hose that runs from the valve cover to the turbo inlet hose puts a lot of oily blow by into the intake tract and intercooler and piping. When oil builds up inside the intercooler, it drastically reduces the intercooler efficiency. To prevent this, many people install a filter onto the end of the hose instead and put a plug on the fitting where it went into the inlet hose. Cheap fix ($10 for the filter) but it makes a mess now in the engine compartment instead of inside the intercooler pipes. This new smaller catch can will hold the oil that blows out, it also allows you to gauge how much oil is coming out. There is a drain valve at the bottom. There are two hose fittings, you have the option of disabling the PCV valve for more crank case pressure relief while making boost.

Overall height is 7 1/2", Body dia. is 2 1/2". Filter is 1 1/2" tall by 2" dia..

Instructions and tips

Balance Shaft Eliminator Kit

Includes a new oil pump stub shaft, inserts for blocking oil flow to where the old bearings were, and a seal for the front balance shaft. Removing the balance shafts will free up 8-12 Hp.

1G BSE Kit (Turbo and NT) $49
2G BSE Kit (Turbo Only) $49

Good:

More HP to the wheels
Zero chance the B-Belt will fail and kill the timing belt
Zero chance the balance shaft bearings will fail and damage the rest of the motor
More oil pressure to the rest of the motor

Bad:

More vibration is felt in side the car (no more is made, just more is felt)
Every car is different, some motors are more balanced than others. It is no worse that any other 2.0 liter car with out balance shafts

Ugly:

To install the kit, you will need to also remove the entire oil pump assy to gain access to the balance shafts. You need to knock out the balance shaft bearings and press in the new block off sleeves. To get the balance shafts out you need to remove the DP, oil pan, the transfer case and drop the motor down by removing two motor mounts and loosening the other two. Even if you are already doing a timing belt, there is still lots of additional work, but they do have instructions. You will also need the oil pump gasket and the oil filter housing gasket for your year vehicle. The oil pan goes on with silicone. It is a full weekend job laying under the car with oil dripping on your face for the average guy doing it at home with the motor in the car.

Wiseco Forged Pistons

Includes rings & wrist pins. 9:1 compression, .020" over-size.

Custom sizes and compression are available but take a few weeks. Email gvr4@roadraceengineering.com if you would like custom sizes.

These pistons have a higher silicon content than the J&E pistons, so they do not expand as much allowing a tighter cylinder to wall clearance than the J&E pistons. However this higher silicon content weakens the aluminum some.

Consult your engine builder before diving into this, as a wrong cylinder to wall clearance will result in either bad piston slap or premature wear.

Eagle H-Beam Rods

Eagle Specialty Products "ESP" H-Beam rods. These rods are made using a 2-piece forging process which results in superior fatigue life. It is made of 4340 steel with a higher nickel and chrome content which is vacuum degassed and shot-peened.

We've had great success using these rods for high horsepower applications. Please specify 6-bolt or 7-bolt when ordering.

$345.00

ARP Engine Bolts

We need to know if you have an early (6 bolt crank) or late (7 bolt crank) motor. Generally the date cut off is May of '92 but with so many cars built just before and just after that date, also a potential motor swap over the years, you need to actually go look. Check at vfaq.com to find out for sure.

Brian Crower Valve Spring And Retainer Set

4G63 Motors - $230

Crower valve springs are wound from a super clean alloy and are recommended for aggressive camshafts and high rev engines. Crower springs are engineered for street or race applications and are the best value in the industry. For those with higher aspirations, Crower partnered with Eibach for the highest quality, race only valve spring available on the market. Drop-in installation, no additional machine work is required. Works with stock valves and keepers.

Crower titanium retainers are CNC machined in-house to insure quality and batch to batch consistency. Crower titanium retainers are the perfect combination of strength and lightweight design and are specifically designed for the Crower/Eibach and factory valve springs.

HKS Cams

The most common combo is the 264 degree intake and 272 degree exhaust cam. For drag queens looking for all top end power, you'll want the 272/272 set. Price includes a cam tensioner tool if you request it at the time of placing the order when you buy a pair.

* Please specify if your car is 97-99, you will need to drill and tap the intake cam for the cam angle sensor to bolt on. We can do drill and tap for you for $40.00

Cam install Tips

Swirl Polished Stainless Steel Valves

Available in standard size and 1mm oversize. These features an undercut stem in the port area. In addition to reducing the valve weight (which provides benefits in opening rate and RPM limits) the radius of the head is such that is significantly improves air/fuel flow. These are perfect for use with stock heads, as well as ported heads. Fully swirl polished. Chromed valve stems and hardened Stellite tips.

Consult your machine shop before buying the 1mm oversize valves. Some (not all) may not be comfortable with using the original seats. Installing oversized seats can get really expensive.

1mm Oversized Swirl Polished Black Nitrate Coated	$229/set of 16
Standard Size Swirl Polished Valves	$225/set of 16

Stock Replacement OEM Valves

$8 Each

These are standard size and the same as stock valves. Stainless steel exhaust valves and steel intake valves. These are available individually, you don't need to buy a full set if you only need a couple. $8 each for either intake or exhaust valves.

Manganese-Bronze Valve Guides

These are OE replacements. Sold individually. Please specify intake or exhaust when ordering.

$6 Each

Viton Rubber Valve Seals

Will outlast OE style seals. Goes well with our Maganese-Bronze Valve Guides. Sold individually but we recommend replacing all 16.

$20/set of 8
$32/Set of 16

HKS Metal Head Gasket

$220

Multi-Layer design for high boost application. Available in 1.2 mil thickness.

Cometic 87mm bore Metal Head Gasket

$120

Multi-Layer design like the HKS/GReddy but this one is design for stroker motors. 87mm bore size and .051" thick.

Factory Metal Head Gasket

$98

This Mitsubishi factory head gasket is similar in construction to the HKS multi layer steel head gasket. It is thicker (lowering your compression ratio a touch) but it is perfect for a motor with a resurfaced block and head to get the geometry correct.

Mitsubishi Stock Head Gasket

$50

This is the dead stock composite factory head head gasket. Brand new from Mitsubishi, not aftermarket.

2G 8.5:1 Factory Pistons

$200/set of 4

Price includes the piston pins. Available in standard diameter and .5mm (.020") oversized. Custom fitting by your machine shop is required to install these on the early 90-92 rods. The early big rods need to be narrowed by .100" and bored 1mm larger on the small end.

Factory piston rings for these pistons are $135 for the set.

Moroso Aluminum Oil Pan

The Moroso aluminum oil pan allows 2 additional quarts of oil. It's best use is in high G-Force cornering applications, but having more oil available all the time is also a good thing. Internal baffles help keep the oil at the oil pump pick up at all times. Even with it's increased size, it still clears 3" down pipes and all the accessories and crank pulley. Studs are utilized and included for the turbo oil drain and to install it to the block sealing surface. An additional bung is provided at the front of the pan for optional installation of a temperature probe.
