My friend and I are gonna try to get 300hp outta my v6. What do you guys suggest we do first along with easiest and cheapest mods. OR whether u think we can do it.

I don't think you can do it. Your best bet to get a max HP rating out of it is to go to a 3.4 block and work your way up there ending with a turbo.

Your best bet is a turbo.

start with getting rid of the iron heads and getting some gen III alu. heads, good cam, good bottem end, headers... 300 is going to be a stretch but their are quite a few people on 60degreev6 getting 200+ at the wheels N/A

go get a fwd 3.1(or 3.4), refresh the block, redrill for RWD starter, custom cam, FWD ported heads, ported intake, full exuast from the heads to tailpipe, stand alone ECM system with coil packs, then turbo.

Nitrous, intake

kariya762

no im not doing nitrous

DemonKnightDK

turbo is your best bet. 6lbs of boost with ported heads should do it.

Along with a whole assload of other work and custom parts just to get the FWD block to fit and bolt up.

Redrilling the starter is not as easy as it sounds, if a genIII block is used, whihc the genIII has the best flowing heads/intake so it woud be the best start, the crossmember and/or oil oan will need to be modified extensivly, you can't bolt a RWD oil pan ont the block due to different bolt pattern on teh block and the crossbolted mains that bolt to the oil pan. Custom left side mount, and a few other custom parts.

If you don't mind all of that, and having limited cam selection, go for it.

I would probaby build a hybrid, using a genI block, preferable a 3.4 block from an F-body, as it will have the crank trigger provisions already, bolt into the 3rd gen, and then use the genIII 660 top end to make it breath like you just took a bunch of antihistamines.

You need to talk to Dave (Daves12secv6) if he can do it I don't see why you can't, as long as you have the money of course, all you have to do is buy the turbo kit from him and then have someone install it for you. You should make 300 or somewhere close, either way you will have the fastest V6 Bird on the street if you put that turbo on there, just get some info from Dave and I'm sure he'll fill you in.

you can get ~350-400 horse out of a 3.1, or more.

the easiest way is:

forced cold air intake
bore out 30-60
head work/better heads
headers
prom work after its all done
msd 6 or 7

keep adding bolt ons from jegs/summit

i made a picklist... and from my 2.8 i range from 350-420 hp... now, i haven't done anything yet, its just a list

rover420

350-420 horse are u serious i'd like to see a dyno result when ur done but that's insane i got my v6 cause i don't want to be paying a fortune in gas but if i wanted hp i would of got a 350

Different people have different goals for their cars/engines. Some people like to do the "cookie cutter" approach and slam in a v8, and some like to be different and make their v6 go fast.
But for 300hp------> Forced induction plus a bunch of other mods like stated above.

ScottieB

2.8 comes with ~135 hp stock. if you look at jegs/summit and add the +from stock on your mods... its easy math. go take a look some day.

as well as you have the pistons, cam, head work, and maybe even new rods for the pistons. part of the head work would be to apply new/better springs for the push of the overbored pistons. the forced cold air intake adds a good amount of horse and is one of the cheapest and easiest bolt ons as long as you know what to do with the sensors. also with the headers, go ahead and run true duals, cats if needed, straight pipes if not.

also putting on headers adds a lot of horse. putting in better gears and building the tranny also helps a lot. the msd and prom burn are needed later to take up the slack from the the performance enhancers. also you may need to get a better distributor. the best thing to do is buy everything and when the block is out getting bored and honed, put the add-ons all in that you would have a pain getting to. so if you need to do any tranny work, or distributor (you know its a pain to get to our dizzys), or whatever, change out this or that... do it. i already upgraded from my stock radiator (v6 iron, or whatever that heavy crappy thing was) to a v8 aluminum. i made my own hose lines with pipes, and i was good to go. just go nuts. we v6's don't need a gas hog to get hp, we can get it through mods. be proud of your v6 with *****... or get a v8.

LoneStar666

you probably believe that you will get 15hp from underdrive pulleys

ScottieB

i have a 383 block i'm building up too, lonestar. do you have a 2.8?

You can't be serious?

Adding advertised HP numbers from the sumit catalog to the stock HP, is just foolish.

There is no way, and this has been proven, to gain hundreds of HP from mere bolts ons bought from a catalog, on ANY engine (well diesels excepted).

The only way I've seen anyone get 300+ HP from a 660, is through forced industion, usually turbo, plus usually a few other changes, like better exhaust, larger injectors, etc, oh and this is with the genIII heads, most genI headed 660s don't break much over 250ish, with a few, VERY few exceptions to thei rule, Tiago, Curtis Walker are a couple that come to mind, both heavily modified with huge porting, and in Curtis' case many bottom end upgrades as well. Both were turbocharged using rather larger turbos and both were using 3.4 F-body intakes. Oh and the boost levels were high, 20ish+ PSIG IIRC.

lmao.........thats the best joke ive heard in months.

lol, that was good, wow. so i should be sitting at leats 250-275hp by now. would dragon seat covers, stickers, and a wing help me too?

ok, gears arent gonna add power at all, neither will msd or any ignition stuff, all those do is help you get the most out of what you have. headers may have added 10-15 AT MOST to a modded engine. i put mine on and hardly felt a difference at all. its too early to keep going, lol, but that was good to wake me up, wow.

AdmAnt13

Come on dude. everyone knows advertised numbers mean nothing in reality.

while I would love to push 300+ out of my V6, I'll go the "cookie-cutter' approach and swap in a V8.

Mic Stylezz

well believe it or not I saw a it had to be an early 90s model ..3.1 z34lumina that was twin turbo getting 342 rwhp at my mechanic..I..I dont like luminas but i gave him props..the point is that he put alot of work into that car i dont know why paint rims racing seats and engine mods but it was still a 3.1 meaning that must be possible to do it in a cam if he found space for 2 turbos anything is possible

drdave88

iTrader: (3)

that is a totally different breed of engine. those come from the factory with 205 or 215 hp. theyre DOHC, not pushrod.

i just reread that, its either a z34 with a 3.4 DOHC, or its a 3.1. which one was it?

Maxboost

Three to four hundred hp from a NA 3.1 !!! Man do some research before posting such **** ,it only makes you look foolish.

Six_Shooter

iTrader: (2)

It looks like you are the one that needs to do some research, if 60degreev6.com was up (It seems to be having issues right now), I would post a link to a 350 HP 2.5L 60degree N/A v6.

Maxboost

It is up,but we're talking about a 3.1 and in all my searching I've never seen a 3.1 make even 300 hp na,must less 400,but would be interested in seeing the details.

Why? Are you also a non-believer?
The origional poster didn't say anything about staying N/A, only no NOS. And the 60* site is still down

All I can say is: Dave, you must post some dyno results on your new motor!
I think I can get at least 400 with a turbo, perhaps we will see...

Mic Stylezz

I asked my mechanic about what engine it was to make sure it was a 3.1 it was 90 cavalier z24 this model : http://sky.prohosting.com/tmhardy/other/8890/mamak.jp I just thought it was an 90s luminda with a 3.1 thats why it was crazy how he fit those turbos in there ..the point is if mitusbishi can make a 2.2 engines at almost 300 hp who says you cant take a 3.1 and do even better

Maxboost

"The origional poster didn't say anything about staying N/A, only no NOS. And the 60* site is still down " Damn ! Your right, I'm spending way to much time on this computer. My most humble apology to all.
