What other mods can I do for HP and TQ without a turbo?

[J.McDonald Knives]

So here is a list of what I already plan to get:
Phenolic thermal intake manifold spacers
throttle body spacers
cold air intake
3 piece light weight pulley set
8.5mm plug wires
NGK iridium plugs
borla catback exhaust
stromung high flow cat
borla header knock off

Ok I know I can get new cams, have the intake manifold and throttle body ported and polished. I still need to find a lightweight flywheel and racing clutch for the transmission off of a Subaru XT. So what else can I do to improve HP and TQ?

[Sarra]

Nitrous

[AJM]

Better Igntion, coil ,and a good tune. Add synthedic fluids all around.

[AJM]

Nitrous

Only if we wants to rebuild his engine someday rather soon.

I'm sorry, but from my experiance when modified much Suaru N/A engines are kind of fradgile.

You won't get anywhere close to a turbo engine's power without it unfortunately.

Any reason why youre getting clutch parts from a subaru xt?

[J.McDonald Knives]

I will be swapping out my transmission and rear diff with ones from a subaru xt because the xt had a 5 speed dual range trans.

[Monkhouse]

I wouldn't bother with the iridium plugs. It's just a fancy name that means "doesn't conduct as well as copper"

[J.McDonald Knives]

I wouldn't bother with the iridium plugs. It's just a fancy name that means "doesn't conduct as well as copper"Then should I go with the double platinums? I am still a little wary about copper plugs because they have to be changed more often.

[Monkhouse]

It really depends on what you're looking for in performance. Copper is the best conductor. Better conduction, more spark, more power. Iridium is a part of the platinum family. It's denser and doesn't corrode as easily. Theoretically it should last longer. On a scale for conductivity, copper is the measuring stick used to rate other metals. If copper is 100, platinum is around 15. Iridim may be slightly better, but it's no where near copper.

NGK copper plugs work best, theyre also what comes from stock from the factory.

Iridiums are supposed to last 30k miles vs. 15k miles of the coppers.

Don't get platinums, for some reason subaru's ej engines hate the stuff, I've never heard of any subaru owner running plats and not get some sort of drivability issue afterwards.

Possibly the voltage isn't enough to drive the platinums?

[Reason]

First you will only need one TB spacer, not multiple spacers. And maybe you should check out members rides and do some reading. ALL the questions you are asking have been asked many times. Plus you can see what people are using. Then if you have a question ask them.

EDIT: :razz:

[Sarra]

That's not very smart. I use iridium in my BK, and IMO, every BD, BK, and BG should use iridium plugs. Why? Because the engine with designed for them. BE/BH, you can use copper plugs without problem, but my BK runs like absolute shit on copper plugs. Besides, it's so hard to change the plugs, you really shouldn't run anything other than long life plugs anyway.

[Reason]

Plugs are easy to change on my legacy ;-)

Can anyone confirm this? That some EJ series engines are designed for a less conductive spark plug? The owners manual for my BE doesn't make any mention of copper vs. iridium plugs. Maybe I'm misinformed, but I thought the BE, BH, BK, etc... designations referred to body style, not the engine.

Um, the BD, BG, and BK had either 2.2 SOHC or 2.5 DOHC motors, when the body style changed over to the BE, BH, they switched to the SOHC 2.5. BD4, BG4, and BK4 were all 2.2, BD6, BG6, and BK6 were all the 2.5's. BE and BH only had a 6 option for the engine code in the US.

The SOHC 2.5 has up angled, high mounted spark plugs, they're easy to get to and to change. The DOHC 2.5 has a non angled, low mounted spark plug, it's in the center of the head, and it's a royal PITA to change. You have to pull the intake, washer fluid res., and battery just to get to them, it takes a good 15 minutes of just pulling crap to get access to them. Then, you have to use a pair of socket extenders and a universal joint to get them out. Since it's so hard to get to the spark plugs, it makes sense that they designed the car to run better on Iridium plugs instead of copper.

[J.McDonald Knives]

Actually my BG calls for NGK plats as the stock plugs. For a better spark what about going to the Bosch plat plus four plugs? Which plugs have a higher spark output, plats or iridiums?

[chuckthefuk]

the only other thing i can suggest is Royal Purple oil and maybe an LSD from a 00' RS but even then its not much of a HP/TQ adder.

I am not sure about the oil though it might be a bad move..

http://wac.addr.com/auto/obs/lsd/lsd.htmlI thought you were talking about something in the engine. MudRat already switches out the LSD's in the trans and in the rear diff so that its full time 4 wheel. Anyone know if it is possible to find a lightweight flywheel and a racing clutch for the Subaru XT?

[caoutback]

WAIT A MINUTE!!!!!!!!!!!!! MudRat!?!?!? Uuummmmmm, you NEED to PM me.

[nosbocaj]

Perfect Power 6 and a tune! I got mine at RalliTEK and the gains were substantial. Better gas mileage, everything is much smoother, and of course, power gains. :grin:

Also, try a grounding kit. It doesn't really provide that much in power gains, but the whole car from front to back just runs much better. Plus it's only about $40 if you go with the Paranoid Fabrications kit.

http://www.rallitek.com/rapeecu.htmlsweet. so looks like I need to find another laptop so that I can keep it in the car. thanks for finding something else for me to spend my money on.:grin: Also plan to get a grounding kit. Just need to have it installed by a pro. I plan to have a few things rewired like the headlights and fog lights, stereo system, and a few other things. for horns I am just using basic high tone and low tone horns like you find in a truck since I don't like the sound of jap horns. Had also planned on moving the horns to the front behind the grill. Might even replace them with some air horns. As you can tell I like to be heard when I am on the road.

[Reason]

Hey with all this money you plan on spending why don't you buy a car with more power? Or a truck?

[J.McDonald Knives]

Hey with all this money you plan on spending why don't you buy a car with more power? Or a truck?Cause my BG is special to me. Besides I like customizing stuff and doing things outside the box. Not to mention that trucks are known to get worse gas mileage.

Ok just checking :wink:

[J.McDonald Knives]

Besides I want to help show the world what a Subaru can do. As it is you can tow 2k with it but I hope to increase that a little and up the HP and TQ to make it easier. And the mods also make it sound better.:grin::wink:

You haven't looked in Members rides yet have you?

[AJM]

I know this will be shocking but I used Bosch IR fusion pluggs in my leggacy with a 2.2 and it ran awesome. Right now it has the NGK Iridum and it seems to run better than with copper pluggs.

Many 95-99 2.5's came from the factory with ethier platnium or irduim I can't remmeber which.

Besides I want to help show the world what a Subaru can do.

What, have you never watched WRC?I'm mostly talking about on the towing. Many people think you are nuts when you tell them that a station wagon or a sedan can tow 2k. I want to push that envelope.

[Huffer]

You better start stripping the chassis and get welding.

You're talking about putting a strain on the chassis as well as drivetrain components.

[Reason]

I don't even think the drivetrain can take that stress.

[J.McDonald Knives]

I only plan on towing no more than 3k. If I have to add some more structure to it I will.

[Reason]

I don't think the drivetrain will handle more than a small boat and trailer or towing a motorcycle or something. I highly doubt you can tow a small car and full trailer. Let us know when you break down.

[J.McDonald Knives]

Its just going to be for a bowfishing boat. The boat and trailer and motor will weigh about 1500-1700lbs. Its going to be a custom made 1660 flat bottom with 25" sides.

[Reason]

It might be able to do it. You figure in the additional strain pulling the trailer out of the water while going up a hill?

[Huffer]

Not to mention the "wet" weight of a boat + gear...

[rougeben83]

I think outbacks are rated like 2500 for towing anyway.

Most unibody cars can tow that amount (something like a small boat or collapsible camper). I know plenty of subaru guys that do it here in MI...it's pretty damn common in Europe to tow with a car as well.

It's just us fat Americans that think towing anything will require a V8. :lol:

[Sarra]

Only the Autotragic Outback is rated for 2500 lbs, the manual is rated for something closer to 1000 according to my manual.

[Mikey97D]

For the '00 Outback, the car is rated for 1000 lbs towing with no trailer brakes and 2000 lbs with trailer brakes. Maximum Tongue weight is 100 lbs.

I've only towed a two rung motorcycle trailer so far with the car with only 1 dirt bike loaded plus all my gear in the back of the car. I can see having a heavier trailer it may be nice to have more braking power. The car handled the extra load very well to my surprise. My gas milage dropped to about 20 mpg with the trailer on though.

If you have an automatic, I would suggest getting a tranny cooler. I wouldn't have a problem towing that size boat for a short distance (under 50 miles) each time.

Have you found a class III hitch? When I was searching for a hitch, the largest I found was a class II.

[J.McDonald Knives]

I'm going to have the hitch made and its going to be incorporated into the new bumper. And I drive a 5speed.

[chuckthefuk]

You might want to look into upgrading to a oil cooler.. You can source an old tranny cooler from any old car and just rig it into your system.

Pulling 3k with a N/A 4 cyl is lots-o-strain on the cooling system.

Upgrading radiator to a Koyo unit w/ upgraded fans will help the little subby chag-a-lug up those hills.

Just a thought though

Cheers

[99SUS SFD]

...and when you crash towing more weight than what is recommended by the manufacturer, have fun with your insurance company. They will not cover the claim. Sure it can "do it", a lot of different vehicles can tow weight beyond their limit...but can they stop them? Can they control them? Is it safe?

Words of advice...don't tow beyond what the manufacturer recommends for your vehicle. You don't need someone else's blood on your hands.

[99SUS SFD]

You're right...you're better off illegally towing your boat down the road.

Extra cost or safety...extra cost or safety...tough choice.

You wouldn't be DD'ing the truck. How far do you drive to your local ramp?

You wouldn't be DD'ing the truck. How far do you drive to your local ramp?I shoot tournaments and have traveled 4 hours away for one. the truck would just sit around and go to waste in between tournaments. And I can have a custom bumper made and get it rated for 2500-3000lbs. I live in Texas and around here you can find places that build that kind of stuff for trucks all the time so it wont be hard for them to fab one up for a subaru. I would just have them do the basic bumper setup and then I would weld up the trim so that I replace the stock bumper. the front bumper I would make myself but will need to find someone with a pipe bender. I know it will be safe using my Subaru for towing. I love trucks but I hate the gas mileage they get and the only way to really find a truck with good gas mileage even when towing is to buy one new and if I did that then I wouldn't have any money for mods for my Subaru. I already got into a big heated debate about this with my buddies and would prefer if we dropped it about me buying a truck and not doing shit to my Subaru. That heated debate even got me banned for a week cause I got so pissed off and told the guy to suck my dick and whatnot. I would rather not be banned here for something like that so can we drop it about buying a truck? Thanks.
