I am seriously moving toward a GTP, my question is for those that own both. How do you find the light to mid throttle response of the GTP to TGP. Maybe the answer will vary with mods, I test drove a 2000 GTP, didn't get to thrash it around, but it just didn't seem as lively with part throttle as my TGP with manual boost control. Appreciate your thoughts, and let me know the mods done to the cars your comparing.

I enjoy driving my girlfriend's 99 GTP more than the TGP at times. For a stock car, her's moves pretty well, faster than my TGP, that's for sure.

In my 1997 GTP Its fun to drive for several reasons, newer suspension, way beter brakes, interior is better laid out and a better factrory stereo.  As for throttle response, it gets into boost @ 1500.  Parts are more readily available, and with over 16,000 members in club GP there is a lot of knowledge for the taking.

I like my early 90's GPs due to the comfortable seats, ease of working on them (although expensive, PM III), and plain old product loyality.

my friend has the 95 GTP and i have a 90 TGP  we both have intakes chips plugs wires and the like.....he has exhasut and i have a major chip........his car seems to have about the same power as mine till ya jump on it and spool up the turbo......if ya drive the tgp and ease down the throttle it wont spool boost as fast so it seems doggy but a quick short stab on the gas will spool it up to make boost and then my car seems to way!!!! out power his GTP........................  so even with not much gas pressure .as long as ya do it quick so in our cars it makes the dif how quick ya step on the gas











did i just ramble on and on and on and on and  on...............oops  lol :roll:

I love driving both cars but if I want to go fast it's my GTP any day.  The TGP just can't hang.  Of course I have lots of go fast goodies to help it out where my TGP is mostly stock.  I do like driving the TGP more if I'm going to be driving on some twisty roads.  To me it feels like it's on rails.  I also think the TGP has more character then the GTP does.  It's rare and I feel like I'm driving something special.  GTP's are everywhere.

Driving my TGP I feel the "instant" response in power and a little delay in the GTP.  Over all the GTP has alot more balls.  The 1995 GTP doesnt have any supercharger or boost goodies so without that its pretty damn good.

 The TGP like already said is a head turner, people look at you and say "what the hell is that".  I was going to shave the badges and make it a sleeper but the "Turbo" fcks them up.  Kids dont want to mess with me in their "Hondajettahundys".  

 They will try to take on the GTP because they all have heard what a GTP is capable of and want to challange it, I smoke them but they will go and brag about it.

 Only one thing about the older GTP's with the 3.4.  You better be handy fixing stuff!  I would call it a "high maintenance" motor.  I already dumped $$ thousands $$ into this car.

Now that i have both i can answer my own question. But it's not really a fair comparison, as the TGP is not much more than stock, a chip that just advanced timing, K&N, 180 stat, manual boost control, no CAT, and 140k miles.  My GTP is at least 40hp up from stock, MSD coils and wires, DHP, CAI, K&N, exhaust, 180 stat, 3.4 pulley.
The GTP wins hands down, after a week of the GTP, I got in the TGP, i almost rear ended somebody at the first stop light, big difference in brakes. Maybe its the tall gear ratio or torque of the 3.8, but that car just seems to want to go with such little peddle effort. And the thing just flies from 70mph, downshifting to second due to DHP, up to 90mph.

The 97+ GTP is a lot nicer and quicker car than a TGP anyday IMO.  The acceleration, brakes, steering, ride quality, noise level, and a lot of other things are MUCH better.  I like TGP's and all, but if I got the opportunity to get a GTP instead of my TSTE, I would do it in a heartbeat.  

But my opinion may be a little unfair, seeing that I am used to my dads '02 GTP that runs low-mid 12's.

B.S. flag!!!

No way are you going to get 40 hp from those mods, no way, NO WAY!!!

So your saying your GTP (3.4L I assume) has 255hp?  No boost or NOS?

"tall gear ratio or torque of the 3.8"???  

The 3800 supercharged GTP is at about 245hp.  You added 40 hp to that?  295-300 hp??

NO FCKN WAY!!!

95gtp.....calm down man :lol: .......no matter which engine he has adding 40 hp is possible.....however  not with the mods he listed,  :D if he is gonna do it he is gonna need more than those few mods :wink: like some of the things i have.....except the turbo'd engines are easier to make power out of ................. :twisted: .................and i personally know a guy ( good friend of mine in fact) who has a 92 euro 3.4 lumina and i gaurantee he has over 240 hp......210 factory......CAI, very free exhaust, biggest chip from ffp, 160 stat, wires plugs,k&n,exhaust timing advanced 13 degrees...............check out the desktop dyno on that mod....that one alone is supposed to go from 210...239 hp@6700 rpm   but i think that noone will argue that he has 240 hp with all those mods and if ya ever saw his car run....wow   we love drivin around and floorin it at 35 mph when his high stall torque converter hooks up after the down shift his tires bark on dry blacktop   in the rain............well............ :twisted:



maybe fla tgp should clarify how he arrived at a 40hp boost over stock :?:

SLOW DOWN there "95GTP"!!!  If you would have read the post correctly he states he has a 3.4 pulley.  That in itself should have clued you in on the fact that he has a 97 or later GTP (3.8L) due to the supercharger.  With the mods he listed it's very possible that he has 40hp (or close to it) over stock.  


MSD Coils and wires - no gain (maybe 1 hp if lucky)

DHP - possibly up to 20 hp gain

exhaust - 5-20 hp depending on what is done (headers, high flow cat, cat back)

CAI - 5 hp +/- a few

180 tstat - 1 or 2 hp

3.4 pulley up to 20hp

Add that up and it's very possible.

I'm calmed down but still skeptical.

Add on HP from mods are not always added together to get the end total HP.  

I know this sounds funny but 20 + 10 + 10 dont equal 40 in these cases.

Yes, I agree with that.  If that's the way it worked adding my numbers up from before would come out to 68 hp over (I wish it worked like that!). But with the mods listed, there is no doubt in my mind he has a minimum of 30 hp over stock, a VERY good chance of having 35 over and I still believe 40 hp is not out of the question.

I believe it's possible that an L67 can gain that much HP gain from just those mods. Those motors seem to gain a lot just from exhaust, and intake alone. Add the DHP on to that, and the 3.4 pully, and it's highly possible.
Every motor responds differently to mods.

The 40 horsepower gain he stated above is not only possible, but is almost EXPECTED with those mods.  Just a 3.4 pulley adds ~25hp to a stock L67 (not to mention 40-50lb.ft. of torque), plus an open air intake and exhaust, and a DHP PCM.  It almost has to have gained 40hp.  The DHP will give LARGER gains when the car is modded, so you can expect usually around 10hp from that.  So that and the 25hp from the pulley put you darn close to the 40hp, and that DOESN'T include the intake or exhaust, or the minor mods like t-stat, coils, and wires.  

But what would I know, its not like my dad has a 400hp GTP and my mom a 290hp SSEi.
