Thicker oil holds in more heat so be careful with that. I'd get good oil press/ temp gauges to monitor the oil so you can see what oil you need instead of guessing. I've also heard a radiator upgrade is a good idea too.

 

I did have in mind to get some gauges to monitor oil, afr and boost. I'll check more into the weight of the oil. Good idea for the radiator upgrade.

 

I guess my list:

Better tune
AOS (I like Crawford or Moroso)
Radiator
Fuel Mods depending on your mod level
Oil Cooler
Larger Sump (Either Killer B or Moroso)

 

Dont forget brakes... Theres a lot of brake work at the track and trust me, your stocks wont stand up for long. and if your giving it hard, youll go through a set of tires in a few track days. unless you're talking just a quarter mile track, but with the mods you're talking about, its a full track, but yeah, expect to go through tires, and brake pads on a regular basis, some people get new tires and brakes every track day. and i wouldnt worry too much about wrapping the intake, and yes turbo blanket, with the cut stock heat shield and a gold wrap on the down pipe saves you from major heat soak, and youll need a lot to prevent it. hood vents would be a good idea, Theres a DIY for making the side engine bay vents work WAY better, the way they are now theres hardly any heat removal from them, some people cut holes and remove the plastic seperators, then put the cover back on and you cant even tell. A new Intercooler couldnt hurt, although not the cheapest mod, Be careful with the oil cooler... do it right basically. might want to look at a FMIC though, stops all heat soak which is nice.

 

I know brake pads and tires are things that will need to be replaced. I was thinking of placing SS brake lines, better pads and better brake fluid. I would like to eventually get a 2 piece rotor for more braking power but also saving rotary mass.

I would like to keep the TMIC because it's subaru signature

Thanks!

 

1. Gauges
2. Seal up radiator surrounding to force air thru it
3. Route air to brakes
4. Steel brake lines
5. Fresh fluids
6. Oil cooler

 

You already have a reliable track car. Just upgrade the brake pads/lines/fluid, grab a helmet and drive it. Change the oil frequently and enjoy it.

 

Your path of modification is going to depend on HOW you want to track your car. If you just want to go do HPDE events, there are really no limits, however if your goal is to eventually go into time trials, keep your mod list in mind as each mod might alter your total allowable "points."

For just HPDE (with plans on continuing to track the car):
Brakes: Good Pads, Rotors, SS brake lines, and fluid
Engine: Some sort of tune, ProTune is even better; high octane fuel, 5W40 oil, and an AOS as mentioned above. Couple this with FREQUENT oil changes and constant monitoring of oil level and pressure.
Monitoring: Boost gauge, Oil Pressure gauge.

Don't worry about stuff like ELH, heat-wraps/blankets, or an oil cooler yet. Do the basic prep to get yourself on track and THEN start changing things...one at a time...to see how it will alter the performance of the car. It is likely that you will find you will want to change sway bars or shocks or springs or tires etc etc etc.

Be careful, the slope is SLIPPERY. Ask how I know! :lol:

 

I'd throw on a power steering cooler if you're tracking a GR/GV. They overheat their power steering systems in the summer on the street. A track could be detrimental to the seals and fluid longevity.

 

I'll add it to the list.

 

From what I've read, the big two are an AOS and a Crawford High Flow Water Pump. They should yield an increase in reliability due to better cooling and reduced detonation. Also, a bigger intercooler to reduce heat soak would be a good idea. A fmic should reduce heat soak significantly, but from what I've read will negatively alter the handling of the car due to the increased weight so far in front. Get an appropriate pro tune for increased reliability.

 

Or a normal priced cast impeller water pump rather than an over priced rebranded "High Flow" pump ... then again for the op, forget the water pump until/if you build the engine lol.

OP, go track your car then figure out what needs to be done, simple as that. Every climate/track/car/driver is different. A good starting point is some new pads, OEM pads suck. Some of the already mentioned gauges so you know what needs upgrading. Lastly an AOS of some kind. Everything else will depend on your situation and you and should be added to the car as you run into a point of needing it unless you like throwing money at potential non existent problems.

 

No one mentioned an aftermarket (koyo) radiator, but i'd throw that in as well

 

I wouldn't go crazy with mods to address a problem if you don't know one exists. For a tracked car, i use water and MoCool, no antifreeze. Even during the summer I have not had overheating issues.

 

GR/GVs don't have as thick a radiator as GDs did. Though, I agree in waiting on something like a radiator until you've determined you need it. It's not like your temps will sky rocket in a few seconds.

 

If your car is in good basic condition you'll be fine on your first track event. Don't spend a bunch of $$$ beforehand. Flush some fresh brake fluid through (ATE is a good choice, gold or blue they're the same), change the oil if you already have a few thousand miles on your current fill, and (as mentioned above) get a helmet and go drive the event. Maybe you'll find you don't even like it, so look at all the money you saved .

 

If it's going to be tracked more than occasionally these are the engine mods I'd do...

- Oil Gauges: temp & pressure. This is essential information on track.
- Radiator: GRs have much less capacity than the older GDs, it doesn't take a whole lot to push them beyond optimal temperature. I really like the Koyo for those on a budget, that's the cheapest I'd go.
- Oil Pan: On track, as perfromance levels increase, you do increase the probability of oil starvation. A performance pan with increased capacity is the ticket here. I recommend a setup made by a company called Killer B Motorsport
- Air/Oil Seperator: As lateral forces increase so does the likelyhood you'll push some oil into the intake tract. The Crawford Air/Oil seperator has a proven record and returns the oil back to the crankcase vs keeping it in a catch can (lowering your oil level).
- Protune: this is pretty self explanitory.

I wouldn't go crazy on the thicker oil. I'd also save your money as far as the oil cooler goes. Increasing the pans capacity with bring temps down a touch, but you don't typically see oil temps rise on these cars until you REALLY start pushing the power levels beyone stock, which is not the case here. So monitor the temps for now and spend that money one something else for now. An ELH would be nice and will help performance, but for a decent one that will stand up to track punishment, they are not cheap. Fuel pump isn't a bad idea, but I'm not entirely sure it's necessary at this level.

 

I don't think a high volume water pump is even necessary... spend money elsewhere.

Also something to keep in mind after you've done a few events: is this going to be just a trackday car, or do you eventually want to compete with it? If you want to compete, be very mindful of your mods. Nothing sucks worse than modifying your car, deciding you want to compete and being stuck between the big bank account, crazy class and having to de-mod the car to step down to a sane person class.

But for now, I'd go enjoy the car as stock as possible. You'll have a better idea what you want out of the car once you have a few days under your belt.

 

Like StripesRX said, I would have to see what kind of mods are allowed for the class I would be running. My goal was to have the fastest street legal car I can build on my budget. This is a long term project so I'll start with some classes and do the minor brake mods. Since this year is almost over, I'll wait for next year.

Thanks!!

What is that?

 

Alcohol Injection or Air Intake is my guess

 

A must have, even for the street is to wrap your intercooler and intake with DEI gold heat tape. Best mod I've ever done. (I'm stage 2 protune with a UEL header)

 

I'll probably do this.
