slick Posted February 22, 2007 Report Share Posted February 22, 2007 Umm... with all the money you would spend modding that 2.8, you could pick up a 3400 for less and still have more power than your modded 2.8. Quote Link to comment Share on other sites More sharing options...

Brian P Posted February 22, 2007 Report Share Posted February 22, 2007 Do you know what boring is? It's gonna be a lot of work and a bit of $ at the machine shop. That said, my friend had bored a 2.8 block .030 over, I think you could go as high as .060 over but it's not like you'll be gaining much power from just the overbore. Full rebuild, New rings, a nice camshaft and lifters from Crane (H260 comes to mind) and matching valve springs will wake it up a little.

Yes i know what boring is and my plan was to completely rebuild the motorcam, crank,pistons,rings,valvetrain, ect. Plus doing al that will allow me to put a good turbo on it Quote Link to comment Share on other sites More sharing options...

digitaloutsider Posted February 22, 2007 Report Share Posted February 22, 2007 Why waste that time on a 2.8?! WHY?! Thats like saying "why waste time on a W-body? Why?" That makes no sense.. it's one thing if you have a L36/L67, Turbo 3.1 or an LQ1. Hell, even a 3x00! But.. a 2.8 has so many things NOT working it's favor, it's not worth the time or effort to mess with. Do some research on the motor first. It has plenty of performance drawbacks. The 2.8 ( besides the Quad 4 ) is a complete waste of time to mess with! What does the Quad 4 have to do with anything? It's 2.3L, not 2.8.

88Regal Limited Posted February 22, 2007 Report Share Posted February 22, 2007 i've always wanted a turbo iron duke lumina, but hey, we all have dreams. Anyways- on the 2.8, your best bet is to put the complete turbo system from an lg5 (?) and get a custom chip from ben. Boring and raising the comp ratio, plus a mild cam will only net you MABEY 45hp. TIP- Do bodywork first noob. Quote Link to comment Share on other sites More sharing options...
Brian P Posted February 22, 2007 Report Share Posted February 22, 2007 crap, my post never showed up. If you want to put the money into it then go for it, I'd like to see it. I would myself do something similar, but would drop it into something light, like a Crapalier or Fiero, and run with that. 2.8's are great for lighter cars, not so great for heavy cars like W's. And it's not like a huge difference between the 2.8 and 3.1 anyway, just slightly less stroke. Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted February 23, 2007 Report Share Posted February 23, 2007 Not sure that you should bore it... however, it would be cool to have a modded 2.8 just because it would be DIFFERENT. BTW Ford FTW lol Quote Link to comment Share on other sites More sharing options...
Canada Posted February 23, 2007 Report Share Posted February 23, 2007 Cylinder boring does increase displacement....HOWEVER, its goal is NOT to increase power....its simply to 'clean up' the cylinder walls for a better seal and less blow by....making more power from it. How much a cylinder is bored is best left to the machine shop and the guy running the drill bit...they do actually know a thing or threvee. If you simply bore any given engine over 0.030" you will make about 4 more hp...given that everything sealed the same before as it did after. Stroking an engine will make a bit more power......forced induction more yet. Quote Link to comment Share on other sites More sharing options...

Im thinking if i bore it out replace everything in the motor it would be like a 3.1 plus i want to turbo it and if i turbo it now it will blow!!! Plus i want to do it cause it woould be different haw many people do you know that have a modded 2.8? it would stick out like a swore thumb.

Crazy K Posted February 23, 2007 Report Share Posted February 23, 2007 bore. no. bore and stroke. yes! hell, I'm sure you could get a 3.1 cheap enough that rebuilding the 2,8 wouldn';t be worth doing. but I would upgrade to a 3400 or something instead personally.

digitaloutsider Posted February 23, 2007 Report Share Posted February 23, 2007 My point is, for a lot less money you could swap in an L67 and put out more power stock than pretty much any amount of resonable mods is going to do for the 2.8. I went through the same stage where I wanted to turn my beater first-gen (my Grand Prix) into some kind of cool car, but then I grew out of it. Spending thousands of dollars on a 2.8 is ridiculous. You won't see the gains that thousands of dollars would do to an L67 or an LQ1. Do some research on that motor and the possibile modifications before you even consider doing this. You'll quickly realize you're wasting your time. Quote Link to comment Share on other sites More sharing options...
zoideraserb Posted February 24, 2007 Report Share Posted February 24, 2007 why are you so deadset on modding the 2.hate? Drop a L67 or just a plain ol 3800 in there, you would spend more modding the 2.8/3.1 to match the power then it would cost to swap either of them in. If you really want to do something different, get a new 3.5L V6 (60 Degree V6 just like the 2.8) from one of the newer cars, build it for boost, contact comp cams and see if they could set you up with a cam with a profile good for a turbo and drop it in and turbo the bastard. It would stick out like hell in a sea of L67s, 3800s, 3.1s, ect... Quote Link to comment Share on other sites More sharing options...
