04 WRX, looking to upgrade turbo
 
Hey guys, I haven't posted on here in quite a while. Anyways, I'm trying to make a decision on whether to drop a new turbo in my wrx or not. Here's the deal, its a 2004 that has been running stage 2 cobb AP, and TBE since roughly 20k miles. The car now has 115000 on it, and the TDO4 is fine and I'm still getting boost, however, the car is going to be paid off in roughly a month, and I'm going to have about 3500 that I could spend for a turbo upgrade to please the butt dyno a little more. However, I have a few questions that I would like to get a general consensus about. The turbo I'm thinking of going with would be the 68HTA and supporting mods, however I haven't decided on a TMIC or FMIC.

1. At 115000-120000 miles is that really an issue when going for a turbo upgrade
2. I know the wrx trannys aren't very strong and I'm running a fairly new clutch of 40k miles, however my 3rd gear synchro has been messed up since about 90k miles...my error in a horrible 3rd gear grind. Would 68HTA be to much turbo to risk with my tranny.
3. For a noticeable turbo upgrade what would you guys recommend if the 68HTA isn't adviseable. I've been in a VF34 WRX and not a huge difference that I noticed on the butt dyno so I would like to think of something more potent
4. I would like any and all thoughts and would appreciate any input on what I should consider with my 04

Thanks Guys

If you really want to do it correctly, get the gears done first. You WILL have more fun with the td04 with a better tranny. By the time the "fun factor" wears off on that, might look into getting the motor redone or maybe replaced before you slap a bigger charger on there.

Is this your DD or fun car?

Has your Maintnence been caught up?
Have you upgraded your suspension?
Will you have the money saved for another set of gears after your turbo upgrade?

You have to take all this into consideration with the mileage you have on your ride now.
Be safe about it so you don't regret it

GL..............CHEERS!!!

I've been spot on on my maintanece, and my suspension is still factory. Here is the deal, I'm going to the Army in October and I'll have the money to put into my car before I go. Once I go into the Army I won't have any bills other than typical stuff ie. phone, cable, internet type stuff. Once I get out of basic and AIT I should have a pretty good chunk saved up that I could do a gear upgrade. Currently the car is a DD, but once I go to the Army it will be sitting for a few months and probably not driven much until I get stationed. I guess I'm just trying to find a way to play with my car a little before I head to basic. Its not something I have to do, I've just wanted a bigger turbo since I got the car just haven't really had the money or time to get it done.

Another thought is, drop a turbo on it, do some suspension work, and once the engine is on its last leg I can rebuild or drop a 2.5 in my car

BLAZE2099 07-03-2012 09:21 PM

That's a decent idea, keep in mind your gonna want to do suspension along with your turbo upgrade.
When I kill my car, it will allow me to go buy a newer one while my 02 gets an awesome build... Or so I plan anyway.
Many will tell you not to upgrade your turbo without doing suspension first. But if your leaving shortly after the upgrade, I don't see that hurting as long as you save up and do it right when you get back.
Your factory shocks are probably on there last leg. I replaced mine at 110kish. And they were shot.
End links, sways ect ect should also be done at this point to further help your car to reach the full potential you want from this turbo upgrade.
Most will also say don't mod too crazy like that with your mileage. But with the engine build in the future, why not. As long as you don't mind bolting things up, just to unbolt them and swap them back in again.

Heck part of the fun in tweaking with a car is tearing it apart and putting stuff together. Hell, I built a motor for my 89 Camaro, and building a wrx would be interesting. Besides the car will be paid off, and I'll probably buy a motorcycle, or a cheap car to get me around if in fact my wrx takes a dump. Maybe I could just go with a mild tune on the 68HTA or just becareful how I drive and just enjoy the get up and with out aggresively driving it too hard until I get my tranny redone. I'm only going to have about 3k-3.5k to spend here in a month...what do you recomend I do. I would like to add a turbo to get a little more kick in the pants, but if there are things that I really really need I can include them in the budget

BLAZE2099 07-04-2012 02:31 AM

20g with supporting mods, than look at what TIC can do for your suspension. 3.5k should get you started fairly well

wrxsnowman 07-04-2012 03:00 AM

I was thinking more along the 68HTA so I don't have the lag of the 20g but good spool and decent topend

wrxsnowman 07-04-2012 03:10 AM

Also, I would do the bushings and endlinks from TiC. However, would stock struts and shocks be fine? I'm not going to do any autocross or anything that I'll really need over the head suspension. For the TiC ones at 845 is kinda killer.

BLAZE2099 07-04-2012 05:00 AM

You pay to play my friend, although that would be fine IMHO. but you would still need to replace your stock struts-$500-1000

brfatal 07-04-2012 11:06 AM

A 20G is a death sentence for his motor.

Suspension and brakes need to be done before the turbo is upgraded. At your mileage your stock struts are past the end of their life anyways. You will need to replace those. Those Tokico D-Specs are what I run, but they are not a good choice for weak springs.

If you're worried about your 3rd gear synchros, making your car quicker will only hasten their demise. With a more powerful car you will be spending more time shifting from higher RPMs.

What is your complete mod list?

He's going to be looking to rebuild, with that in mind, his options are endless.:D

So I've been doing some thinking. What if I just did a vf39 or 16g turbo with the cobb ap map, and get a pro tune, with a TMIC. I figure VF39 or 16g (except FP doesn't make just a 16g, its the 68HTA so it seems) wouldn't be as killer on the engine or tranny.

Also, I've already decided I'll do the suspension, at least new struts, sway bar and bushings. However, just a few thoughts on that.
1. Since I'm not going to be autocrossing or road racing, are the TiC Tok D-specs really worth it over oem struts or STi pinks? As it looks right now for the TiC Tok D-specs with springs and stuff I'd be looking at around 1500 which I'm sure would make my car crazy good handling
2. Assuming I just went with OEM struts, would it be wise to replace the springs or just basicly rebuild my suspension to OEM spec and get a rear sway bar?
3. I would rather not have any drop in ride height as I like to play on dirt roads, and I have been known to drive places that need a little bit of clearance. I kind of use my car just about anywhere I can lol

So in a nutshell.. I'm thinking to try to keep it as cheap as possible for now since I'm going to be working with a 3k-3.5k budget I would do this

OEM Struts
Whiteline 22mm Rear sway w/endlinks
Bushings set from TiC

VF39/16g maybe the Blouch 16g
TMIC STi, or turboxs with STi splitter
Pink injectors
Walbro pump
Inlet hose
Up-pipe or de-cat the stock

And possibly the fuel rail if needed with this setup

So do this and enjoy it until I go to basic in october, then when I get out of basic and AIT I can think about putting PPG or Type RA gears in my tranny. PPGs are crazy pricy, but from what I'm reading the Type RA really aren't that much stronger than stock, 15-25%ish

Just some thoughts I've been pondering
