urfsin Posted January 25, 2013 Share Posted January 25, 2013 I have a VF39 right now with probably 60,000 or so miles on it (I picked it up used so I don't know for sure). I thought I heard a very slight grinding noise coming from it while I was on the freeway yesterday and I tried to duplicate the noise today, but I had no luck. So now I am thinking I might need to start looking for a replacement and finally pull the trigger on an aftermarket turbo. Let me first say that I am quite happy with the performance of the VF39. There is nice quick spool up and while the power is not "big" by any means, it's still pretty nice. Edit: I found my old dyno graph and I was making 278 HP and 301 TQ on cali 91 octane. That all being said, I wouldn't mind a nice little bump in power. If a turbo could to get me to the 320 to 330 HP range and still retain good to decent spool I would be happy. I'm not really interested in going above that power level because my car has 85,xxx miles and it's my DD. I feel these power levels are within pretty safe limits of the stock block / pistons and I like that. Here is a little background on my power mods: 850cc injectors, fuel pump, custom upgraded TMIC, up pipe and a full turbo back exhaust but that's it. My intake is stock with a drop in K+N filter and my boost control is stock. I am not interested in adding anything to my car except a new turbo. So here is what I was thinking for my options. I can get a billet wheel for any of these and I think it's probably a good idea because it will help spool to the best of my knowledge. 18G -TD06sl2 (7 or 8cm) 18G -TD06 (7 or 8cm) 20G-TD05 (with a 7cm, it's the "smallest" of the 20g's, but I was thinking this might have nice quick spool and decent top end) 20G - TD06SL2 (7cm or 8cm) 20G - TD06H (I really think this would be overkill, especially with an 8cm and my limited supporting mods) So what do you think? I would especially like input from members who have experience with these turbo's and mod's similar to time. Thanks in advance.

lee07 Posted January 25, 2013 Share Posted January 25, 2013 I'd go Avo 380 or hta68 or if you want stock fitment, vf52 Stage 3 came unexpected/ unplanned to me so I just went vf52 but if I planned and researched, Avo 380 would be what I would have gotten Link to comment Share on other sites More sharing options...

urfsin Posted January 25, 2013 Author Share Posted January 25, 2013 ^^ Thanks, I read that already. I am looking for other opinions. I see you have an 18G, what variety and how much power did you make? Slide It Sideways Link to comment Share on other sites More sharing options...

wurkenman Posted January 30, 2013 Share Posted January 30, 2013 You will love the 20g. You can always tune back a little too. If you woke up today, you have another chance to do it right. Link to comment Share on other sites More sharing options...
JMLegacy Posted January 30, 2013 Share Posted January 30, 2013 Where do people go to but turbo's online? I surely don't want eBay. Link to comment Share on other sites More sharing options...
urfsin Posted January 30, 2013 Author Share Posted January 30, 2013 20G-TD06SL2-7cm Thanks, I was sorta hoping you would chime in. I have been doing quite a bit of research since I started this thread. I was always drawn to the TD06SL2 compressor wheel because it seems like a good compromise between the TD05 and TD06H. In regards to the 7cm vs. 8cm: From what I have read, the only bad thing with the 7cm is that you can get boost creep (then have to go with an external waste gate). That is NOT a road I want to go down. The TD05 with a 8cm seems like an interesting option. There are guys out there running these and the dyno charts look pretty good IMO. I forgot his user name, but one guy is a member here on the forum. Slide It Sideways Link to comment Share on other sites More sharing options...
urfsin Posted January 30, 2013 Author Share Posted January 30, 2013 Where do people go to but turbo's online? I surely don't want eBay. Not sure what you mean. You can buy IHI, Mistubishi, Forced Performance, Blouch, Garrett and other turbo's online and they are all good. While I agree that most turbo's on e-bay are a joke, there are a few brands that are OK. You just gotta do your homework and find out what company is ok and what is not. Kinugawa is a good example of a legit "ebay" turbo. They use the same parts as a lot of "big name" turbo companies. Slide It Sideways Link to comment Share on other sites More sharing options...

urfsin Posted January 30, 2013 Author Share Posted January 30, 2013 Thanks man. Did you know I still have those race brake pads I bought off you?? I still have not been back to the track.

But, buying a used one is a gamble especially if bought online on a forum like this. Link to comment Share on other sites More sharing options...
urfsin Posted January 31, 2013 Author Share Posted January 31, 2013 So wait, you've been two times rally X champ with an OBXT? If yes, that's cool! Well, not really. I was the California Rally Series champ in 2008 and 2009 driving my year 2000 2.5RS. I competed the 2007 season in the OBXT and I never finished higher than 6th (I was a rookie, what can I say?) My 2.5rs was out of service for one race though and I brought back the OBXT out of "retirement" and I ended up getting 1st in that race. That was 2009 I think. It just goes to show you its 90% the nut behind the wheel that really matters. Slide It Sideways Link to comment Share on other sites More sharing options...

V8Bait Posted February 2, 2013 Share Posted February 2, 2013 If I were iin your shoes I'd go with an BNR hta68. Decent do low and holds till redline. Would probably give you around 320 -330 on a mustang dyno with a conservative tune. Could go with an 18g but you will have to push iT pretty hard to make 330 on 91oct. Again, I'm basing this off a mustang dyno. Link to comment Share on other sites More sharing options...
urfsin Posted February 2, 2013 Author Share Posted February 2, 2013 OK, the sound was really starting to bug me so I did some poking around my car and it turns out the sound was from my front passenger side brake heat shield rubbing ever so slightly against the rotor. I could only hear it on the freeway I think because of the speeds. I bent the heat shield away from the rotor and now I have no more noise. So now I don't think I need a new turbo. The thing is, I am all revved up on buying one now!! I guess I know what I will go with when the VF39 finally dies. Slide It Sideways Link to comment Share on other sites More sharing options...
