I hear what you are saying but for most applications which are more for recreational street and occasional track use they should do ok. I am hoping that mine will be very streetable with a 2.76 gear and I hope to drive it all over the place. I believe the combination should still run in the Low 9's, High 8's. If they spool later I will smack it with a 100-150 shot of NOS and boost control it with the EBC through the 1-2 shift and have the NOS Timed to shut off sometime before that. We soon shall see.
Well Ryan, you are the first I heard of an end user where a knock off came apart. I still have not found anywhere where these gt45 ebay knock offs have done the same from an end user. I will soon find out what this combination can produce on the Dyno. It will be Chassis Dyno'd once it is installed in the car also.
On the Diesel forums there are guys totally abusing the Knock off GT45 pushing well over 50PSI and over 50K miles on them with no issues at all. Maybe they are just lucky.
There is a rebuild kit for the ebay GT45 Knock off.
