I've searched but not finding the info I'm looking for. I was going to get a knock off but figured ill step up for a good gate.

I'm looking for a gate for my pt88. I plan to run fairly low boost (7psi) next year so I figured a 60mm wastegate is a must. (Correct me if I'm wrong). I'll turn it up when my other motor goes in


Seems like the precision 66 is a few dollars cheaper but if the turbo smart is a much better unit I can handle that. I've found them within $30 of each other. Lots of good info on the turbosmart but not a lot on the precision unit.

Thanks for your opinion!

They are both great I dont have any preference. I wondering if a single 60 would even be sufficient at that low of boost. Might need to do a twin gate setup.

Buy the gate with the biggest diaphragm, "the bladder under the spring"
The gate with the larger bladder will be easier to control.

Have you thought about jgs?

I looked into jgs but a 60mm jgs was the same if not more then the turbosmart or percision.

Now if a jgs 50mm would work then that would be a different story. Just didn't think a 50mm would take me that low on boost.

I used one Turbosmart 45 on my PT88 on a 5.3 and it controlled at 14psi very well with proper gate placement.

Id use the JGS 50 and save some money. Make sure gate priority is very good.

I've always had goodluck with turbo smart I've been using them now for almost 10 years or so and never had a issue.

My tial 44mm controlled down to 5 psi with a t6/85mm turbine and now 6.5 psi on my t4 tc7875.

This is both on the same motor and cam, stock ls1.

Either gate I would hope would do the trick.

I'd love to save some cash with a jgs 50mm but didn't think it would allow such a low boost setting. I'm trying to keep the stock motor alive until a certain show I go to every year with a group of friends so I'd be even more pissed to use a 50mm and not be able to keep it under 7psi

Lol. I'm trying to keep a stock drive train together until my lq4/80e/8.8 is all ready to swap in. I figured it's to exensive to do all the drive train plus turbo kit at one time. I just don't have the funds for that kind of winter project lol. So I'm building the kit first then this winter I'll put all the drive train in it and turn it up!

I run a precision 66mm gate. It has controlled my 91mm down to 6psi. I am happy with it.

FWIW you wont ever run it at 7psi lol Use any of the gates mentioned. Personally i like tial since they are made in the US and they look the best JGS work well but are FUGLY in my opinion

On my stock LQ4 I was able to gate my boost down 3.5psi (spring pressure) with a 60mm JGS gate (AMS 1000 w/CO2). It worked great!

It is not enough now to gate the new 403 methanol setup (boost creep) so ordering a second 60mm to address that issue.

I will only use JGS, way too much luck so far on many projects with JGS to change. Just my $0.02.

Heavy H.P.

Wheres a good place to buy the Tail waste gate from?

Call Darin at RPS awesome guy to work with and he got me the best pricing. Also whoever you order them from make sure you find the ones that are newer as they come with all the springs instead of one you order it with.
