i would say like others, turbos can be really reliable if it is done properly the first time. I have had my Inline Pro kit for over 2 years now and I have not had much issues with it. The main initial issue was my downpipe bolt had backed out, but then I got some locking bolts and no problem. The only other issue I have had with the kit was the wastegate bolts backing out, now I just retighten them once a year and problem fixed, it only takes about 15mins. I have also taken my car on long trips before as well, 1500miles with a lot of boosting and she still keeps on ticking with that said, Mase's kit looks to be great

 

wouldnt a Bolt on Greddy Kit be just as reliable as a SC?

 

I think the tuner and installer are just as important as the kit. I would look to get something tuned by one of the top tuners in the country like a Jeff Evans or a Mase and then have your kit installed by someone whos installed several of the same kits. While it may be simple enough to do it yourself someone who has experience with it will be able to know the little tweaks and various nuonces with the kit.

I have a full race gt30 kit installed by minitoyota whos installed at least 10 full race kits and then I went ot Evans for the tune. I'm running high boost of 15 which is very low but the car is a dd an sometimes I can put 1000+miles on it in a week. So reliability was priority #1. I also have a restrictive exhaust but with this I'm making 425 to the wheels, 280 tq and there is almost no lag since I have the gt30. boost hits at 2300 rpms.

 

How much should you expect to pay for a nicely done turbo AP1 with less than 50k miles?

 

For the whole car complete? I'm sure it varies wildly depending on year, condition, mods, motivation of the seller, etc. This belongs in a different thread though.
