Thread: GT vs GTP Performance Differences

GTP's overall performance compared
to the GT.

about 5 - 8 pounds of boost

well me personally, i owned a GT, and i traded it in on a GTP. i LOVE the difference. like, the GT i felt like had to work as a DD. the GTP is much quicker and feels like it just tackles DD like a breeze.

plus, you can make MORE boost with teh mods. GTs are limited in that field.

most will recommend top swap for more compression, im lazy and dont like scrapping for parts, so i opted for newer cleaner better car

good luck!

GT>GTP. Top swap it. Better gears and more power.. /end

i own both a gt and gtp.

yea the gtp pulls way harder then the gt. stock for stock,

but i feel like you have to give the gtp more gas to get it up to speed, because it only has 2.93s vs gts 3.29s.

gtps whine of the blower is a plus

I had a 06 n/a and also have a 98 GS (same as GTP). My car is mucho faster that my 06 ever was. Its all about the boost man.

the GTPs are going to be faster that the GTs. rated for 40 hp >. but with the blower on there you have more potential for modding it. you can make a GTP fairly quick for cheap. in order for the same performance out of a gt youd prolly be looking into some type of forced induction, depending on how fast you want to go. the most common being the top swap. with a top swap ( gtp top end on Gt lower end) youre running a higher compression that a GTP, making the TS'ed GT faster... but also more problematic and prone to detonation

they arent like imprezas, evos, or srt-4s. those cars are (practicly) always beat on. GTPs on the other hand are owned by a broader spectrum of people. you could find one that has been beat to absolute dust by the highschool kid who thinks its a race car. on the other hand however you could find just as many that are owned by old ladys that drive it once a week never bring it over 3 grand and have all service done by the dealer on time.

hope this helps, good luck

gtp has a blower and beefier trans thats about it other than that all the suspension and handling is the same stock for stock the gtp is 0.8-1.0 seconds quicker to 60 the gtp was suppose to be like the all out version of the gt but then it became its own sub model

yea although people think GTs are race cars for some odd reason. 155whp isnt much to brag about. unless its in a miata

ha thanks, yea that too. its really awsome when you have to drive around with no supercharger belt

^ 160-165whp sir

haha is it?

this guy that has a stock gt, (who always has to race anyone and everyone) there was dyno shootout and he only made 154 for his best.

that is the 3.4 DOHC motor. it makes more power than yours, even being n/a.

could you get a series 1 SC motor in a gp pre 97?

As much of a PITA as the 3.4 DOHC is...I'd rather have it over the Series I S/C motor...more power as well...and 5spd? Yes plz

DOHC all the way! my DOHC will (well before my trany just started acting up) could beat some 3800 SC cars! a gear swap, intake & TB porting, and some crazy tuning put some massive gains down. that being said...

if i had another car i would consider rebuilding my DOHC and doing a turbo with a newer 4t65 trany. but money isnt in my favor so after 220,000 miles of DOHC my Z is getting a top swapped l36 and new trany. out of the box it will be as fast as mine is now, if not better and have better mpg. add to that my list of mods going in to it and she will be a sleeper that nobody is going to expect. there is a highly mod'd Mazda 3 Speed running around in my area that has a bunch of work done. that thing is quick. stock they are good for 14.1 in the 1/4 so im thinking he might be in the mid 13's with what im planning i am shooting for low 13's to 13 flat in daily driving form and a dip into the 12's with race gas, a smaller pulley and my system and tools taken out.

As for the OP i would say keep your GT and do a top swap on it. the trany you have has a better gear ratio the GTP's 2.92 will help on the high way but i think the 3.29's are better around town. as for the difference between the two trany's 4t65e and 4t65eHD the diff is all in the "Diff" Differential that is. the HD has a bigger and stronger diff. i honestly dont think the HD diff is needed unless you plan on doing burnouts and beating on it. that being said i have a friend who put an M90 SC on his DOHC (might have seen the pics of it sticking thru the roof of the car...) he had his non HD 4t65e Diff last 3 years of running at the drag strip and doing burn outs. 3years was the limit though... as the diff went boom... with pieces flying and fluid on the ground.
