Wanted: VF43 Turbo,STI intercooler,or VF39 Turbo Wanted: STI intercooler, VF39 Turbo, I have an 07' Wrx and am hooked on swaping these parts with the stock wrx parts. Any sellers? I'm looking for the parts to be new are very good condition I still have less then 10k on my car and I plan on keeping it for a long time.
^ I checked it out, I'm considering it but, You potsed "exact mileage unknown" Do you have any idea of a ball park for the number of miles on the turbo? and of course $400 best price?
if you wanna stop by I got a brand new 20g I'll let go for $750.00 it is a td06h and is brand spanking new... I'm in St Cloud.
I have a brand new vf39 that was put on my car today...might sell it, pm me an offer with an offer for my sti tmic as well and I'll think about it. Although the turbo gets more and more miles everyday.
vf 39 You don't like it? you just put it on. VF39 with little miles $500? I'm researching what they are worth so sorry if I low balled it too much. TMIC STI like new no bent fins? or small birds stuck in it? $300? once agian I don't know what they cost new, so sorry if I low balled it too much. -Michael
Thanks ^ Just a question, Are the VF39 turbo very pron to cracking? Is the VF 43 alot more durable. Which is the best for the money?
The VF39's are notorious for cracking, though there's some fixes people have come up with (I haven't done much research on this). This doesn't mean that it absolutely will crack, however. The VF43 supposedly fixed the hotside cracking problem, so if it's a major concern to you you would probably want to get a 43. I personally have a 39 with no crack on it, and I'm not terribly worried about it as a problem. It's not for sale if anyone is wondering.
Nice find Lee. The cracks aren't a problem until they propagate out towards the wastegate flapper. Downside is loss of spool, and if the crack is big enough, you won't hold boost as reliably. Most people only look for the crack on the outside of the exhaust side (where the turbo meets the downpipe). The cracking actually starts inside the exhaust housing and you can usually only barely see a hairline crack if you look into the uppipe side.
I have an STi TMIC without the tubes in the back. It's in perfect condition: $225. Tubes run ~$80 used on NASIOC, so you'd save a few bucks in the run.
Check craigslist, there was one on there a while ago for pretty cheap, i was going to pick it up, but then my car took a **** so i didn't
michael48...can I ask a silly question? Why would you settle for a vf39 on a 2.5L? injector size? otherwise you may appreciate the bigger turbo (16/18/20) on the 2.5L....any turbo that doesn't choke like an asthmatic kitten (vf39) above 5.5K just curious
first off, I don't know alot about the diffrent avaiable turbos out there, and second I want to have strong power to the wheels that won't need to be serviced or repaired every 10k miles. I Just want strong and reliable power. Any recomendations what is a 16, 18, and 20 turbo? Is that the best way to go?
16g, 18g, and 20g...I'd do some more research before going with the vf39. It may be the right turbo for you, but at least compare options first.
the only thing I'll tell you is to take your time and research the best turbo for your long term power goals & driving habits. I'm not saying the vf39 is a bad turbo at all...but there's so many options out there. The 2.5L can effectively handle a larger turbo without major lag issues. a 16/18/20g would deliver you better top end power while still providing a good amount of mid range punch. you can go onto nabisco (nasioc) and find tons of turbo information.
I would honestly suggest going with an 18g from the research I have done. I have been looking at vf39's and the like as well for my 07 TR. An 18g will provide the same if not a little bit more midrange power and will be able to hold a lot more boost to redline resulting in more topend power. A lot of guys say don't go any lower than a 20g, but on a DD I am of the mind that a 20g is just to much, as it would benefit most from a FMIC bigger injectors and much more supporting mods than would be required for an 18g.
The vf39's were a great value 2-3 years ago when they were going for 200-350. Now that they are in the 350-500+ range, a used MHI turbo is a better value for only slightly higher (if not the same) cost. I'd strongly recommend against buying a new vf39/43 like you had mentioned in pm. Way overpriced. For the 2.5L, I'd say 20g is a better fit over the 18g. Mild tune (less torque) if you're really worried about the way you drive (gears and clutch). What is your budget and what are your goals?
Ding ding ding, we have a winner. As already mentioned on this forum, if you want to stick with stock injectors, a 7cm hotside TD05 18g is going to perform much better then a VF39. Totally agree, except for the last part. VF39's are insanely overpriced now-a-days. On top of that, MHI turbos beat IHI turbos on both spool and top end. I got my used 18g for $500. I've seen a number of 18g's and EVO3 16g's on NASIOC for $600 or less. As for the 20g vs 18g argument, it all depends on how much power you're looking for. A 18g will net you full boost around 3k, and can still make 300 WHP. A 20g can make upwards of 340 whp, and spools around 500 rpm later. If you want the extra power, 500 rpm isn't much to wait. All in all, if you're looking for a suitable alternative to the VF39/43, a 18g or EVO 3 16g are your only options. Both can be run on a basic stage 2 2.5L car easily. A 20g will likely require additional mods.
Very interesting, My goal is to reach 300 whp/ lbs tq + Reliable, and able to take some auto cross driving. I want to do the job right so if I have to spend more then I planed I will, but as of right know I would like to get the Turbo 18g or 20g?, I would like to use a larger top mount intercooler then my midget sized wrx intercooler, and am planing on using a cobb turbo back exhaust. I already have a cobb access port and I will be able to load some diffrent mapping once I get the hardware bolted on the car. My budget $2500 to $3500 completed. I will most likely have Mike Wray install the parts he is a nice guy who seems to have alot of experince. Mike always has some cool stories about a rally race too. -Michael
Yes, regardless of which turbo you pick, you'll need a bigger TMIC then the stocker. Here's how I see it: If you're just looking for 300 WHP or "close enough" and don't want to shell out for a VF39/43/48, etc. A 18g or big 16g are your only other small options in the same price range. A 20g will make significantly more power, but you'll also for sure need injectors and possibly a clutch or gearset (although depending on your driving you may need either or both of these with the smaller turbo's as well).
And a Bullwinkle TO0nZ. Speaking of which, can I hire you to do a touchup tune on my ride sometime in the next month? Part-throttle type stuff, I think I'm getting some hesistation and whatnot. OP: YOU GOT INTERCOOLER. See ya at Firestone so you can get it.
^ Thanks, and the vote sounds like the 18G is the best way to go based on my goal of 300's at the wheels?
Excellent, I'm glad you're not thinking vf39 anymore. as many have already praised, an 18g with a 7cm hotside (to reduce lag) might be the best route for you.
I plan to post up a comprehensive tuned car breakdown once I get mine installed. I've got logs/road dyno's from each stage of my '06 .
Fall sucks, plus I keep scheduling to tune other peoples cars on weekends . I'll shoot you a PM and we'll get it on the calendar.
