gotta do my water pump,timing belt,all aux belts,fuel pump,and injectors.
so what else should i upgrade all at the same time??
camms?
pulleys?
intake manifold?
??

or swap motor?

 

What are your power goals? What do you have done now? Why is this in the classified section?

 

350-400
going for looks and performance

dont know if i should keep upgrading this wrx motor with high mileage or if i should swap motor?

 

I'm saving for a motor/transmission swap because I know its will eventually happen with 100k+ on the clock, its just a matter of time. Right now, I would say not to upgrade anything and just sit on it until it either breaks or you simply save up enough money to do it. You can always sell a high mileage RUNNING motor.

 

The best way to get a reliable 400 whp is to sell your suby and buy an evo.

Realistically to get 400whp, the easiest way would be to switch to a 2.5L block. Big turbo. Bigger injectors. FMIC. Bigger Fuel Pump. Possibly meth. Cams would help. Then you're clutch is going to go out or you'll break a gear (hope for the first). Then we haven't even started going for looks yet, that's a whole another balll game. My suggestion, buy an Evo.

. I couldn't get even $200 for my running EJ205 Shortblock with 130k on it. I ended up just giving it away. Nobody wants a high mileage 2.0 block.

 

John hit the spot, not just my GSPOT!!LOL.. But on a serious note, our subie's are notorious in making globs, well not globs of torque like the v8's but similar to it. But on the HP side,its possible to hit 400whp but that'll consist of upgrading alot of motor related parts. Actually there is a HIIC member that already has 400+ whp on his STi but he got the Cosworth Stroker Kit iirc and stroked his 257 to 277 with a funky a$$ clutch.LOL.. and a stock TBE.LOL Just FYI.. You wanna see 400+ hp, the evo's 4g63 can hit that easily but idt their torque numbers will be comparable to the flat4's.

 

Omg.

 

your running stock injectors with a vf39? also no tune? no fuel pump?

there is no difference between the red USMD STI intake manifold and the silver WRX one you have. The JDM versions are also the same (with a few minor cosmetic differences for the lack of emissions). The only one that's different is the JDM STI Spec-C which is one long runner that has no TGV assembly. You could do a TGV delete but I'd make sure you maintain your investment first before throwing more money at it.

Do the maintenance on your engine. Change your spark plugs, fuel filter in the engine bay, both belts, change the timing belt and automatic tensioner along with all the bearings associated with the timing belt area. There is no need to spend extra money on aftermarket timing belts since the stock one should be changed at 109k per your maintenance schedule. It should have been checked for signs of wear and cracking at 60k. Change the water pump AND thermostat and depending on the hose conditions for your water pump you should definitely change those as well since they get hard and brittle.

If you're there and willing to go the distance you could do like I did and change the crankshaft sprocket when you replace your oil pump. Be aware this isn't an easy task if the gear is stuck. You'll need to buy the shim for that gear as well (forgot the exact name). Due to your mileage you may want to also replace the timing belt tensioners on the timing belt cover. Get a cosworth timing belt guide since you're there as well.

oh there are a few seals like your rear transmission seal and if you're going to change your clutch soon or haven't done this yet... change the rear main seal. You'll need to drop your trans for that one. If you change your oil pump you'll need to change a small o-ring behind the oil pump as well as a brown seal that goes in between the crankshaft and the oil pump itself. I'd be best to do whatever can be done when you're doing your maintenance and in those areas. It'll get costly but if you plan on having your car around for a while and plan on upgrading you'll want to insure all is in working order.

change your trans/diff fluid and rear diff fluid. if you haven't done it already flush out your coolant system and run new coolant (replacement radiator hoses (OEM or aftermarket), radiator would be best at this time). flush your brake fluid

Check your valve covers to see if your valve cover gaskets are leaking.

bottom line before doing any FURTHER upgrades have a plan.

master brake cylinder bracket, stainless steel brake lines, fluid, pads, rotors is a worth while upgrade - immediate difference in performance.

FYI: there are bugeyes in the mainland running around or approaching 300k on their stock engines and their still putting power down.

 

this thread should be closed. this topic has been beaten more than a perv with a **** mag on his pecker. OP research sorry to be so BLUNT but I got the same attitude when I was a noob. search, search, search, and search some more. plenty of good info here and on NASIOC......

and to caveat on what Jon was saying, some tuners tend to agree that Suby motors break in after 100k

 

holy ****, thanks for all the help and info guys...
specially to infek, thanks man...
ill keep my wrx motor then, do al the maintenance and upgrade from there...

wow really tuners agree our motors break in after 100k mileage. sick!!!!

read this thread it is very eye opening...

 

wow i learned alot from this, thanks man

 

I have to agree...and is in the wrong forum anyway. Please read the first few threads on the Hawaii section. People in here that have ben here for a while don't like to see the same questions pop up every now and then, so please search. Also, come to the meats...ask questions, introduce yourself...you'd be surprised as to how much info everone has.
