Site has been a bit boring lately, I guess I'm no help.

Well this forum has been kind of boring lately. Other than this:
Anyone Interested in a Zombie Apocalypse Ready TourX?
With a little more work, it could be Batman’s mom’s car.

I guess no news is good news, I have not seen posts on major mechanical failures or other horror stories, Just a bunch of trial stuff.

It is inevitable that I will be doing something to up the power put to the ground with my TourX. I can’t leave almost well enough alone Not that the Tour X is slow, If fact it is sort of swift, but sure is not exciting, never mind scary fast.


Reading this just gets me all excited and tingly
V60 Polestar

Given the TourX is a Buick and the transmission’s torque capacity is 480 N-m ( 354 lbs-ft) and the LTG’s cast pistons have been known to shatter ring lands under high boost, there is a limit to power adders.

I figure close to 300 wheel BHP and 350 lbs-ft on 93 Octane just might make the TourX a 14 Second flat / 100mph trap speed ¼ miler, while not breaking either itself or my finances.

Simple upgrade plan is:

• A tune, leaning toward Trifecta.

• A catted downpipe.

Catted downpipe with O2 sensor

• A Mama Bear sized Turbo.

Here Are some links I found regarding getting into the internals of the LTG 2.0L motor.

At some point when it is time to replace, I will go to higher performance tires, Grippier Pads , Stainless brake lines, & and high boil point fluid.

Maybe shock, if there is real gains to be had.

That’s the Plan,

Comments and suggestions welcome?

Car and Driver published a road test of a FWD Sportback and said it ran 14.1 @ 101, if I recall correctly. Now, the AWD system would add about 175 pounds; I'm not sure how much heavier the Tourx body is, but I think your goals are attainable.

A flash tune is where I would start. As a newbie to Buick, I’m not too familiar with the different options, but given that it’s GM they’re not hard to find.

I agree that overboost is a grenade waiting to happen - as it is in most set-ups using stock internals (again not sure how stout our engine is). However 300 at the wheel seems very reasonable - I was using a simple Burger stage 1 on my 328i (4-cyl turbo n20 engine) and was somewhere around 270 peak. I dropped in a high flow Pipercross air filter (ok - so these really don’t make any gains) - but I got it for free and it was the only other thing I changed.

Not sure if there are tunes using e85, but that might be an option to explore?

Catted downpipe would be a nice addition. And it’s pretty reasonable (looks great too!)

Can the stock intercooler handle a bigger turbo? Will there be more lag?

And while the AWD does weigh more, it sure is a nice advantage for getting off the line.

Intrigued to see what you do here - I’m always interested to learn about performance 🤔

Since you said the forum has been boring lately, I'll stoke the fire with some controversy.

I'd do shocks / springs well before I'd do a brake fluid 'upgrade' as there would be instant gratification from the suspension change. I can really only see the brake fluid 'upgrade' being useful for full day track events, but even then I'd spend money on a set of tires specifically for that day before I'd change the fluid. Don't even get me started on stainless lines... I'm still running the OEM kevlar w/ rubber coating lines at 300k miles on my '03 TDI, so unless the quality of the brake lines seem jank I won't be touching those.

Of course, these are just the ramblings of the 'R Man.' Definitely keep us posted as you progress on your upgrade journey as I don't plan on doing anything more than a tune for quite a while. I figure if the original turbo is still going strong at 200k miles, I'll retire it for something bigger and tune accordingly.

Also - some good discussion here on Trifecta tune

Boost does not shatter ring lands from anyone force inducting an engine. It is detonation from the resultant ecu tuning that could cause problems.

ZZP put 400 who on their 2014 ATS 2.0T with just a handful of modifciations.

I was just about to recommend you contact ZZP. They do make parts for the LTG, and maybe some things can come over. They are building a 2.0T Camaro right now.

I wonder if they would let you test some compatibility of parts.

Since the TourX is primarily my wife's car and I have my 3 toys, I'm probably not going to go crazy modifying. I might just retune it myself once HPTuners opens them up. I'm not happy with their stock transmission stuff.
