Whether or not you go to another VF39 or a VF22 or VF34 or something equivalent or larger, something you could do is to either get the tubo ported & polished or do the P&P work yourself.

Deadbolt can certainly do the P&P work ($195 for an IHI turbo) http://www.boostplanet.com/services.htm and there are others on the board who do P&P work but I don't know what they charge.

You won't have any issues with work from Deadbolt and some on the board have gotten good reviews for their work also.

The P&P will smooth out the air flow through the turbo (going in and going out) and this will give you a slight increase in spool (300 - 500 RPM) w/associated torque increase.

If you want to maximaze the results of the P&P work and your upgrades, EM will be necessary. Everyone has their favorited for EM, and you have a number of options to choose from (Hydra, Ecutek, COBB, possibly others)

why not just stick with your current blown turbo and have it rebuilt?

your choices seem limited within your budget so this might be your best bet.

IHIs arent worth the trouble. You can get another VF39 off ebay for a couple hundred bucks.

The 16/18/20G turbos are MUCH better units. As said earlier, IHIs pretty much suck. But if you are going to buy an IHI, lok for a VF22 first, although good luck finding one under 1400 bucks now, if at all, then a 34 then a 39. I wouldnt put a 30 on it unless I HAD to.

What do you guys think about a VF23 on an sti? Is it worth spending alittle more money on that instead of the 39?

It's been said before....IHI turbos are junk and should be overlooked completely. If your looking to replace the stock turbo but you don't want a oversized turbo then look into a TD06h-18G. I'll never stop suggesting these turbos for the sti- 18g, 20g, sz49, sz55 depending on your goals any of those turbos would be great.

Whats the price range on a slightly used one? Can I also run the car with stock injectors and pump and be able to wait alittle to get EM?

Please don't do that. Wait until you have at least injectors, pump, EM(I love ecutek). You don't want to risk anything on a 30k+ car, I say do everything all at once and don't peice things together bit by bit.

Not sure on the price of a used 18g but I'm sure you can find one a lot less then you would for a new one if you look around.

If you only have $300-400 just get another vf39, like this guy's ^^^, to get you back on the road, then save up these items as they will be needed all at once for an upgrade: em, larger injectors, 255 lph fuel pump, and larger turbo (fp green, 20g, etc).

Excellent. I plan to upgrade the turbo in the future but I don't want to move to a FMIC for several reasons. Keeping the TMIC is a must for me so I have been looking for aftermarket turbos that will fit that bill. Thanks for the information.

I ran as big as a sz49 on my spearco tmic so I would hope you could fit much larger turbos on the stock tmic.

Well I was more concerned with heat soak than anything. Of course it is depends on the capacity of the stock TMIC but I would guess heat soak is a bigger issue with an aftermarket turbo.

The tmic will get hot no matter what because of it's location but with my 20g in there wasn't much heat soak to talk about, the big ass scoop really does its job. If your worried about heat soak you can get some turbo wrap the unabomber always talks about

There are plenty of Used Lower mileage PE1820's on this board and others...

It's a good upgrade in my eyes...will fit easily, ball bearing, not a huge upgrade but will easily make 300+ whp from 14.7psi-24psi...If you want to keep it moderate, run like 17psi on it, with the other supporting mods, and I'd say you'll easily reach 300whp and 320tq range, with similar to stock spool, and metter mid and upper range power...

They are selling around $700-$900 used...about $1500 new... (it's a waste of money new for that price)

All you'd need is a mild injector upgrade (depending on boost, some people are using stock STi injectors), Walbro, turbo back, TMIC (stock or aftermarket)....and a tune...

I think it's a good idea...

Default at least 20g

I wouldn't consider a turbo upgrade for myself unless i went with a 20g at least, green, zilla, red, etc... After that I'd look to SZ49/SZ55. The supporting mods required will be injectors, fuel pump, and some other stuff. So it will cost way more than it looks like you are willing to spend. Anything else just wouldn't be a significant enough improvement imo. Buying another stocker ( there should be plenty of them) and getting a tune isn't a bad option. I've seen guys make close to 300 wheel plus or minus some. Other than that, I would save for 20g.
