2015 vs 2018 GT

[Mikaelernesto]

Hey guys!

First time poster, long time lurker.
Currently driving an R33 skyline manual with 370hp but looking to get into a mustang. I’ve only ever driven a 2018+ mustang and found the manual to be disappointing especially compared to the A10, part of this being how long the gears are in the manual. Here in Australia I don’t believe we have hearing options when it comes to ordering the car.
So my question is, if I was to buy a mustang for daily duties and occasional track use, would I be better off going the new GT with the A10 or the previous generation (manual) and use the spare cash to upgrade the car, FBO, potentially even putting a supercharger on it. Is there much of a reliability difference between the two models? I’m much more interested in the mechanical benefits of each generation as I like to tinker.

Also pictures of modified mustangs would be great for some inspiration!

2016 Owner here while I love my car. I have the 6r80 and not the 10 speed the 2018 is worth the extra dough. The 6 speed auto is really really good but the 10 speed is insane. I have a 2018 IM so Im making similar to 2018 stock power levels and the a10 will still walk me. Also personally I would pass on the MT82 I\\

I have an 18 manual and would only recommend getting the mt82 if you can't live without shifting yourself. Otherwise go with the A10. Just my thoughts.

If you want a manual the 15-17 MT-82's are much better gearing wise.Or you can get the 18+ PP2. If your sick of shifting, A10 can't be beat. Dunno why peeps always harp on the MT-82.. must be the s197 crowd complaining about theirs

I just found, coming from a 25 year old skyline, that the shifting experience didn’t inspire much confidence. I love shifting, but I love peace of mind when it comes to performance. I’ve been doing a bit of research and it seems the Gen 2 coyote is the preferred choice for boosting, but a lot of people seem to also just go FBO with the gen 3, in auto and are more than happy with the performance.

All that being said both platforms seem to respond very well to modification, is the newer generation worth the additional 10-15k? I will be buying second hand of course.

I you want the A10, then it's only the 18+. Otherwise whatever tickles your fancy. Is it worth it.. all depends on what you really want.

From what I've heard, the Boss 302 from the 5th gens were pretty mean on a track. There's a pretty big price delta there if you can get them in Oz. I wouldn't want it as a daily over my s550 any day, but as a track toy it's worth considering.

Yeah they aren’t even worth considering he in Australia unless you’re a collector or REALLY want that specific model. I’m definitely keen on the S550 just torn between the two.

A10 all the way then. It's a marvel of modern engineering.

If that's the case, the why's the PP2/GT350/GT350R only available in a manual trans?

 

[WildHorse]

a DCT

That's not a A10. Haha.
Edit: An it's not a debate, it's genuine curiosity.

 

[Mikaelernesto]

Definitely not a manual vs auto!! I didn’t like the long gears of the 18+, I like to row through gears, I live in Sydney so being able to pump through gears is fun, automatic 10 speed also makes stop and go traffic easier + is silly quick acceleration.

so if my understanding is correct, then gen 2 coyote motor’s lower compression lends itself better to boosting? But the gen 3 will provide a better NA experience? Is the piston slap/ticking cases I’ve seen something to consider? I know the internet has a way of pumping up issues of the few which can shame the many.

18 up PP1 with a10 hard to beat. I have crossed shopped everything in the 35-40k new range (actual buy $) and nothing still comes close especially after adding a $450-600 E85 tune. Shit is bad for n/a 302.

I have both the a10 in my 2018 and the m6 in my '19 Bullitt. I couldn't stand the long Bullitt (all 2018+ GT manuals) gearing. When I put a PD blower on the Bullitt all the gearing came to life. That said, the A10 is MUCH faster than the m6 stock for stock. If I could only own 1 it would be the A10.

Lower dynamic compression you can get more boost. However, total CFM (in and out of the engine) is the key to it. gen3 n/a coyote not so much, cause frankly you can spend a under $500 and get the same performance from the gen2 engine. The A10 makes all the difference in the 18+.

Interesting. So if I were to do a FBO set up with a tune (98 grade fuel in Sydney) on a 2015-17 I’d get similar performance doing the same with a gen 3

also interior wise, is there much difference between the two outside of the digital dash?

The interiors are the same other than the Digital Dash which can but put into 15-17 except that the 15MY have sync 2 so no apple carplay/android auto. If you do a 2018 IM swap on a 15-17 it makes almost exactly the same power as an 18+. Probably more since you have a tune as well. I had a S197 with the MT82 so as stated maybe that is why I hate it so much but it blew up 3 times on me and the car was only FBO and blew up once at stock power.
