Default Quick VF39 + EJ205 Question

About to get a brand new EJ205. I'm wondering how reliable a vf39, Sti pinks, walbro fuel pump, and an Sti intercooler would be with an EJ205? I havent found anything really related to reliability. I just dont want to ruin a new engine after having to pay for it. Car would receive a road tune after mods are in.

Will be as reliable as the person tuning it... How hard they push the setup and also depends on how aggressive you drive the car.

I have a vf43 on my ej205 and the setup has 20k miles with no issues at 21psi with the colder temp tuned to 20psi----- output was 301whp/303wtq

I had a new EJ205 shortblock from subaru, bolted up 04' WRX shimless bucket heads, and put a VF-39 with no shaftplay on it with deatschworks 565cc injectors and a walbro 255 (same flowrate as the "Pinks"), it's lasted 30k with no shortblock related problems, mostly just maintenance stuff and things that break that I caused from working on it and it's still running strong

If ur driving style does not change u wont see a measurable difference. W more power im sure one tends to use it more. So u will likely see less mpg when romping on it. I still got 22-24 mpg

A well set up 2.0 is verry under rated IMHO
They are tough sons of Biatches when done right and looked after - OP run it and enjoy it, good for you for not going the hybrid route

You got some solid tuners in your area, your engine can take way more then the 39 can give when done right.

To the Op I've got 30k on my VF43 @ 20psi and it has been abused but taken care of with no problems what so ever. Good street combo for a daily driven car with moderate power. I get 26/30 (I never go below 3/4 tank) for mpg and only run Shell, BP, and Sunoco 93 fuel. The key to mpg is keeping you alignment good, maintenance done, and air pressure where you want it. Getting on

I do get maintenance on my car often along with alignments. I've always gotten ****ty mpg with my td04 even. I posted a while back and heard that my mpg is normal... I kind of questioned it where on average i get 250 miles on a full tank running stage 2. I've also tried cleaning the MAF as well before. Don't notice anything drastic in change in mpg.

My td04 is fully spooled at idle? What do you mean? I drive normally.. not really any spirited driving much. Commuting to work and home on the daily... Do you think something's wrong with my tune? Im using cobbs stage 2 ots map 91oct...

I was getting 26-27 mpg with stock injectors stg2 on my last two wrx's. Now with id750's and a vf34 I'm still getting 26mpg.

There is either something wrong with your tune/ bad tune, or you drive like a jackass. I think it's your tune though since you said you drive normal.

It is probably my tune then... Will look into it. Don't know why it would be because it is a basic ots stage 2 map from cobb. Will see if anyone else has any ideas for this. With the gas prices up in so-cal, I would love to get at least 300 a tank and save a trip to the gas station once a week.

Because your tdo4 is smaller... It spools a lot faster... If done right you can hit full boost ~late 2k range to early 3k which decreases mpg.

My vf isn't too much bigger but doesn't spool as quick as a tdo4... Takes longer to boost by a few hundred rpm and that's where cruise territory is ~3000rpm-~3900rpm hence the better gas mileage.
