Pt7675 or boost lab 7675
Pt7675 or boost lab 7675 Hello im building a budget build 5.3 th400 going in a trans am and was looking at these two turbos. The pt7675 is a cast wheel and the boost lab 7675 a billet wheel for cheaper price a anyone have any experience on these two turbos thanks
I have a PT7675 that I ordered with the cast, but they shipped it with a Billet wheel. On both my LT1 and 5.3, it starts getting boost about 3K and is all in (up to 29psi) by 3500. A great unit. I've not heard of boost lab. I have tried the ON3 7875 and 84mm, both T4 flanged, and they didn't seem to spool as nicely as the PT7675. On both those ON3, I simply put them on the hotside and ran them without changing the tune one bit. The PT7675 has taken my full street trim 96 Z28 on DR to 6.4 @ 112mph in the 1/8th. No where near maxed out. This was on E85 thru a full cat back exhaust (Borla), driven to/from the track with 50lbs of tools in the hatch. Now I'm going with twin GT35's. I still have the PT7675 and the hotside as backups if the twins don't work out(I'm doing all the fab work myself) by Spring.
boost lab is on the level with china turbos and not in the same league as a precision turbo. If you wanna go with a cheap turbo that works with good customer service go with vs racing. ive used vs racing turbos with no issues.

They ARE the bomb, as far as making power goes, even I will concede that. It's the reliability that is sub par, ESPECIALLY for the price they ask.

I've personally seen them toss compressor/turbine wheels, break shafts, spew oil.
Ever see those pictures that float around on the internet of people pulling turbine wheels out of their downpipe, hood, etc? Those are all older Precisions.
I can't justify spending 3-5x as much for a turbo that might make 10-15% more power with the same reliability.
Precision has come back around over the past few years with quality. There was a point also that you couldn't pay me to run a PTE turbo. But I've switched back and pretty much only use them now in twin setups that I build. I still use Borg units on a lot of the single setups. Since PTE started doing their own CEA wheels quality and power are badass.

something like a vs racing or on3 7675 or really any decent Chinese 7675 clone will be absolutely fine for a budget setup unless we are talking about trying to squeeze out 800+ out of it. no need to spend 2x-4x as much if you just want 600-700whp range

Consider yourself lucky, I had one let go with about 10k on the clock, and had to make that embarrassing ride home, you know, the one where it looks like the entire car is burning down. I remember I was sitting at a light (ever notice how long the lights stay red when something is wrong with your car and you REALLY need to stay rolling?), anyway I'm sitting there engulfed in a oil filled cloud, and this guy starts motioning to me to roll my window down. So I do, and he says "hey man, your car is smoking" as if I didn't know. So I continued on and gassed out the whole subdivision to complete my embarrassing ride home.
The Turbonetics T7875 has been a very reliable unit and made good power on my LS1 and I paid $800 for it used with maybe 500 miles on it.
I see them pop up on here from time to time, great value and rock solid dependability imo.
