Well, the bug bit again. I should see a new turbo in the mail in a week or two. I found a 39 for $400 out of an 05 sti with 7k on it. I will of course get it and then have to mail it right back out to have it ported or tear it apart and do it myself but I really do not have the time and I do not think I did that good of a job the last time.

I will now have to get some injectors from Frank and mail them out to be modified. Andrewtech will do the same thing as Perrin but will gaurantee a matched set which is something that Perrin apparently does not do as I was told. Cost will only be about $40 more.

I will then need to either get my hands on a header or get mine ported from somewhere but porting the stock XT is really not worth it as it is so small to start with.

Lastly, I will need to get my hands on an AP. I am going to take my time with all of this so it should be done by the end of March.. Just kidding. I am seriously shooting for some time in May/June time frame for all of this to be done.

Wish me luck!

Good luck and inquiring minds will be waiting to see how it goes.

I will see what sort of magic deadbolt can work on this turbo. Maybe clip and reballance the wheel or soemthing. Once I get the turbo in hand I will give them a call and see what we can do. My big concern is boost spikes though as I do not want to go external so the port should take care of that.

I've gone the same route, my VF39 is ready for porting and my STi manifold should be here in a few days! porting your wastegate will fix any boost creep issues.

is this a similar setup to your 300whp setup? I have a feeling the ported STi manifold should flow as well as any aftermarket $ header.

This is pretty much the same set up except for the injectors. I did not do them last time. I did have a Borla header though but it cracked and took me about 2 months of hell to get it replaced. I then sold it as I wanted nothing to do with that company. I figure I will probably just pick up some cheapy header from ebay but that means replacing the up pipe... what a pita that is.

Have you talked to Crucial Racing about P&P the stock headers? They are now offering this service and many people seem to be very happy with the gains gotten from it.

It is my understanding that the hole diameter of the the STI manifold is larger than the FXT. Some place does this same sort of porting and you simply pay them a core charge until you ship theirs but I think I read that they are not even taking the FXt manifolds as it is not worth their time.

If I remember correctly, the STi, WRX, and F-XT manifolds are identical.

Besides, I don't put a great deal of stock in headers on a Subaru anyway... we made 616whp on Dan Lowman's car on the stock headers, so I doubt the header is a weak point.

Why upgraded injectors with the 39? Do you expect to see gains over not having the injectors? How much gain if so?

 

[DamSedan]

I did not change them last time and I was ok but a little on the high side if you will. The goal was to stay below 80% of their duty cycle. I think I was closer to 90. I am also thinking that somewhere down the road I will have an 18 or 20G so I might as well go ahead and get it done.

Interesting. Stock are 550cc, modded I think they become upwards of 800cc? How would that effect fuel economy (if at all) and normal driving?

the STi manifold has a larger internal DIA than the FXT, the crossover pipe is also different so porting and STi header is well worth the $160.

Chris, I actually have 2 FXT ecu's right now, both ECUTek'd, one is yours, the other was Vhalin's... I'm using Vhalin's while the other one gets retuned from Kingpin.. but once I get that one retuned, I'll be selling the other spare... watch out for it in about a month or so...

Interesting. I may have lost my mind, I thought they were the same. Maybe the STi manifold changed at the same time that the up-pipe design switched in the middle of MY04.

Was looking around and found some Perrin injectors for a good price. http://www.iwsti.com/forums/showthread.php?t=43670&highlight=perrin+injectors

If you do not see something on here from me talking about running an AP, hit PM me as I would not mind getting the old one back as I know how it works!
