tgpguy21 Posted November 20, 2003 Report Share Posted November 20, 2003 how much hp do you guys think a 3.1 litre could put out if it was rebuilt and had all of the good fixings?? (cold air intake, exhaust, so on) i know i can find 3.1s alot easier than a 3.4 and it would be easier to put a 3.1 in my gp se. i just want to know about what they would run. any help would be much appreciated. :guns: :fruity: Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted November 20, 2003 Report Share Posted November 20, 2003 I would guess around 225-250HP n/a and who knows boosted. 300+ isnt that hard boosted Quote Link to comment Share on other sites More sharing options...
tgpguy21 Posted November 20, 2003 Author Report Share Posted November 20, 2003 what do you think a gp with 225-250 hp would run in the quarter?? do you think it would be easier just to rebuild that and put that in, instead of a 3.4?? also does the 3.1 and 3100 take the same tranny cause mine was just rebuilt and only has like 3,000 on it. sorry about all the questions but i wanna give all those ricers something to compete with.

You're looking in the good lower 15 or high-mid 14 second brackets. Since you already have the 3.1L, easier rebuild; plus you'll have better results, and a wider selection of parts. Depending on year, the 3.1L and 3100 have both the 4T60-E. - Erik Quote Link to comment Share on other sites More sharing options...
tgpguy21 Posted November 20, 2003 Author Report Share Posted November 20, 2003 well in you opinion what is it easier to find parts for the 3.1 or 3100 and which would you recomend??? Quote Link to comment Share on other sites More sharing options...
Redfox340 Posted November 20, 2003 Report Share Posted November 20, 2003 Many of the pushrod motor parts are interchangable; so all are pretty easy to locate. As for companies, you'll mainly need to go on specifications, personal testimonies and warranties. - Erik Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted November 20, 2003 Report Share Posted November 20, 2003 225-250Hp wouldnt cost that much............. Quote Link to comment Share on other sites More sharing options...
joey b Posted November 20, 2003 Report Share Posted November 20, 2003 do you really think that 225 ponies would run high 14's? The 3.4 has just less than that (215 for 96) and runs high 15's, unless you do mods which will obviously give it more than 215 hp. In addition to that you won't have the "long legs" of a 7K redline to get it going. Quote Link to comment Share on other sites More sharing options...
no1kicker Posted November 20, 2003 Report Share Posted November 20, 2003 the TGP has 205 stock and runs 15.2, so that's not too far off. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted November 20, 2003 Report Share Posted November 20, 2003 a 5spd has a lot to do with getting an n/a 3.1 in the mid 14s, but it can be done with an auto. 3.1L has torque, especially a built one. DOHC doesnt. Quote Link to comment Share on other sites More sharing options...
Intlcutlass Posted November 20, 2003 Report Share Posted November 20, 2003 Perhaps a better question is "how fast can your wallet go?" I stole that from somebody on these boards...... Good luck , however you choose to upgrade...... Lee Quote Link to comment Share on other sites More sharing options...

Jon89le Posted November 20, 2003 Report Share Posted November 20, 2003 This should be an interesting thread. Well let me just say what i did. Just on the motor between all my internal work and bolt ons ive spent about $3300 and my GP runs a 16.6@79mh. Pretty crappy huh? The only things i have left to do are the exhaust and intake. And this is with an upgraded tranny. I figure after i do the 3x00 intake swap i may go to around high 15s simply because i have really ported heads already. The quickest N/A GP that i knew of was Chris' (GPXSS) GP which ran a mid 15 and he did basically the same stuff as me with the addition of the top end swap. I do have pretty good 60ft times even with my 17" chrome rims. With the torque thing i definitely have to agree with that comment. Ive got 245/45 Dunlops wrapped around my 17s and even with the sticky ass rubber, if i romp on her she'll spin for about 4ft. Forget brake torquing, thats just fun... . But thats just my little scenario, i personally will never do another 3.1 n/a. too much money spent and nothing to show for it... Quote Link to comment Share on other sites More sharing options...
Vegeta Posted November 20, 2003 Report Share Posted November 20, 2003 DOHC doesnt? It has more torque than the 3.1 stock, so I guess the 3.1 has no torque. I did the same thing, wasted lots of money on a 3.1 building it up. You need the gen 3 top end to do anything with an NA 3.1. Otherwise, you are wasting your cash. And headers, gotta get headers on there somehow. Quote Link to comment Share on other sites More sharing options...
Jon89le Posted November 20, 2003 Report Share Posted November 20, 2003 Yea Ben, so you feel my pain. I like the short headers, i believe its Curtis, that are on his Z24. Quote Link to comment Share on other sites More sharing options...
MaroonRegal Posted November 20, 2003 Report Share Posted November 20, 2003 Robby, what would you do to get 225hp out of it N/A? Quote Link to comment Share on other sites More sharing options...
Vegeta Posted November 20, 2003 Report Share Posted November 20, 2003 Just start with a 3400 if you want 225 hp. That or get a cam and swap the top end and make some headers. Shorty headers will help but they are designed for top end power...and even then they should be a decent length. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted November 21, 2003 Report Share Posted November 21, 2003 Robby, what would you do to get 225hp out of it N/A? High compression, big cam, headers, bolt ons. Sounds simple right? Quote Link to comment Share on other sites More sharing options...
Jon89le Posted November 21, 2003 Report Share Posted November 21, 2003 Its that damn intake and exhaust. They are major bottle necks. Id love to see what a 3.1 would do with custom equal length headers and custom intake manifold. I think those two combined with what Robby just said would be very nice.

phantomFE3 Posted November 21, 2003 Report Share Posted November 21, 2003 ok i didnt even read everything on this thread but i can tell you from reading like the first ew posts, ITS A WASTE OF TIME! why the hell would you want to spoup up a 3.1 anyway?!?!?! to spend all that time and hard work and money on something you MIGHT be able to get into the low 15's?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!??!?!?!?!?!? WASTe!if your looking to go fast for cheap buy a mustang 5.0 and your already there, spend a few more dollars on the VAST VAST VAST aftermarket for the 5.0l ford and go even faster, its that simple!!!!!!!!!!!!!!!! so unless your going for the title of "fastest NA 3.1 in a w-body" like i once tried, and failed, since i figured out it was a lost cause, then i would suggest wasting your money somewhere else, or giving it to me. BUT ANYWAY if you want to (try) to make it fast, here is what you do: buy an aftermarket cam for it, it will usually come with the lifters and srpings and retainers and all that stuff, get the biggest damn cam you can get somehow get ahold of some 3100/3400 heads and take them into a machine shop and have them ported and polished, as well as the upper and lower intake from a 3100/3400 and have those ported and polished and all that jazz then you make a cold air intake (a real one) and then you get a free flowing exhaust and run synthetic oil, and while your at the machine shop, have them rework the block and rebuild that so its like brand new find some aftermarket valves and pistons and rods and crank* *=if you can find them, they might be hard to find but they are out there AND/OR you might have to spend alot of money on them, titanium valves will help alot but they are expensive and thats how you would get some horsepower out of a 3.1, even if it isnt that much and if your gonna race it, get a 89 or 90 grand prix 2 door, they are the lightest platform arent they? and strip that fucker out just to the bare metal, if your wanted to make it fast oh and dont forget the strongest head gaskets you can find! and then run some juice, that would probably the easiest, just replace the head gaskets with the strongest you can find and then run some giggle juice through it and voila! its almost like a microwave, sure you can heat stuff up in the oven, but its a hell of alot faster and quicker and EASIER to use the microwave Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted November 21, 2003 Report Share Posted November 21, 2003 All that stuff wont cost that much if you do the work yourself. If dont know how to do the work yourself, you shouldnt even be bothering with modifying it. Quote Link to comment Share on other sites More sharing options...

If dont know how to do the work yourself, you shouldnt even be bothering with modifying it. are you saying you have the capabilities and knowledge to do all of that? and honestly, i think your wrong. that is why these people have jobs and thats why the field os growing all over the world, not everyone has the capabilities to have this kind of service done to their engine and whatnot Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted November 22, 2003 Report Share Posted November 22, 2003 Yes, I have to tools and know how to rebuild a motor. Its not rocket science. The only thing I will pay for is to have my block bored out. The rest I will do myself. Why is that so hard to believe Quote Link to comment Share on other sites More sharing options...
89oldscutlass Posted November 22, 2003 Report Share Posted November 22, 2003 Everybody expects mustangs and camaros to be fast. Thats why its fun as hell to see people build a v6 w-body and see them take down a mustang or camaro. Thats what makes it worth it the look on there faces when a v6 hangs with them or beats them. Hell anybody can take a sbc chevy or ford and get 300+hp out of them but not everyone can do it with a V6. Quote Link to comment Share on other sites More sharing options...
