Default Turbo suggestions

Iam working on sourcing my parts for spring on my 04 Wrx. I am debating on a couple different turbos now. The car is stage 2 if you wanna call it that. Sitting in my garage now is a 3 port, ewg with 38mm MVS, motive auto works composite tgv deletes, agency power rails and lines, and a fmic. I know I got the damn fmic for FREE so don't bash me. I am torn now between a 16gxt , 16gxtr or 18gxt. The car will hopefully push a little over 300 with spool around 4k. What do you guys suggest? Want a meaty mid range and top end

What is your goal? Just 300 to the wheels? What is your budget? Who is your tuner and what have they said?

I'll be shooting over to EFI Logics in Ct because I am not to far bit yes 290 minimum would be nice. Talked with them briefly but figured I'd see what's your guys word.

If 290 corrected numbers are your minimum on that dyno. Look at a 20G or bigger. For full spool of 4,000 on an average setup, look at a 16/18G.

I like the spool I see on the 16gxt 8cm but don't understand why the xtr hits so much later. And if I am looking at an 18gxt don't know if I want the 7cm or 8

Because it has a bigger hotside. Your goals mean you want the 16gXTR. You would do very well to read the text below my username and consider carefully that 16gXTR serial number 001 is on my car.

I vote 16gxtr it would take some good tuning and supporting mods to make the 18g hit full boost by 4k

18gxt turbo 330 awhp and 300awtq @ 23psi. Full boost at 3500ish. The only complaint I have is the car is too slow, now.

LC set at 5600 with 15psi ready to go. I love it.

Fmic with an EWG. But keep in mind boost doesn't kill motors detonation does. Back the timing down a bit at a certain rpm and boost pressure and it should be fine. Of course you will sacrifice torque. But I'd rather have an engine run this hard for 60k miles with compression results around 165 on all 4. Timing is the key to these motors. Some guys tune lots of boost no timing or vise versa. Depends on your tuner and what they say is "ok"

The only reason why I say an 18g is because I maxed the turbo out at 24.5 psi. It was on throttle surging and stalling after the EWG was introduced. And I have a 40pound turbo. Not sure what a big 16g will do.

Yeah Brother Eddie your numbers sound pretty much like what i am after. What dyno were you tuned on and do you have a sheet I could peek at. If your still hungry why not e85 or meth? I see you have a 6sp.

No E85 around here. There is a sheet floating around here before the EWG. It was 330/277. The dyno was IAGs non corrected dyno (dynoJet). And I'm not messing with meth. Just too much of a hassel for me. I don't want to keep checking levels and all that. I jut want to get in and beat on my car with no worries.

Got a great deal on a Subaru rebuilt 6speed I couldn't pass up. Truth be told I was getting the car ready for a fully built 2.5 that I'm working on now.

Plus e85 or meth would need a new tune and bigger injectors for the e85. I got as much as I could reliably out of my 2.0 Many will argue differently but 60k miles and a compression of 165, I'm quite happy with the results and reliability.

Thanks for the reply I think you pretty much sold me on the 18gxt. What you said is exactly how I feel. I wanna get a strong reliable daily without having to step up to a 2.5. If I want to go any faster I'll just sell the car and get an Sti

A lot of people will say it's too laggy or takes forever to spool. I have EL header with a 38mm tial EWG, fmic with a 3" intake. I love it. From idle I have 8-10 psi and that's fine for the around town driving I do. But merging, its a whole new animal. In the right gear 10-23psi takes no time at all. But you should always have 10psi whenever you need it. But that does depend on the tuner and the tune. I would never go any smaller. There is lag, but when the boost hits, it hits hard. You will get used to the lag and learn how to drive around it. It's not that serious.

Yeah no elh for me maybe a port and cross pipe but that's it so I figure if I can get a decent tune I'd be around 3800 - 4000

Just search the classifieds/ebay for an EL header. I have gt-spec and love it. People sell them a lot. It took me 2 years to make the final decisions on what I wanted before I pulled the trigger. With the EL header you don't lose much rumble and it keeps things quiet. I live in a highly police active area so I needed to stay as quiet as possible.

This kind of stuff bothers me.

First: "Full boost 3500ish". How are you judging that? Eyeballing it is a very inexact scence, honestly on the road its tough to distigush full boost of 3500 from 3800.

Second: 330whp on a dynojet equates to about 287whp on a standard mustang dyno. Right about what I'd expect. Mustangs read about 15% lower than Dynojets IME. SO even with EL headers, FMIC, and EWG, on a solid car, you failed to meet the OP's expectations. And from what I gather he wont have all those supporting mods you have either. Which will lower power and add to lag.

My position stands. Unless you want to dump extra money into EL headers, and if you want to make 290 + whp corrected (aka legit numbers), go with a 20G. If you want spool, go with a 16G.

I don't think he might have misconstrued it slightly but I know what he was saying hes seeing good boost by 3500 with a turbo that size the transient boost response is good with nice tq down low. As for the power levels I guess its kind of irrelevant as it varies from weather conditions, dyno, car, and supporting mods. I
