Who sells em?????

I heard not many for the 60 degree V-6's
I just do not want to have to keep to stock one if I don't have to when I get the cam and all.
230ish rwhp motor and exhaust set up and a stock converter sounds like bad news to me.

whats parts are going to give you 230 Rear Wheel Horsepower

you do know that equates to about 300 HP at the flywheel, right?

 

I'm 99% sure that Transfixleo (on the Trans board) has a v6 f-body, and rebuilt his 700r4 with an aftermarket convertor. You might want to try a search (or post a message or email to him) and see if you can get a name/price! And if you find out, let us know!!

Is that motor going to be n/a, or sprayed/boosted? The TC woudl probably be fine, but you'd probably be better off with a higher stall convertor anyway. But I'd be more worried about the rest of the trans- especially if it's the original GM one from 1986. (Did I mention I'm on my 3rd trans?)

 

91teal rs, it's not that hard, a nice cam and some porting jobs will get you up there in the 180 range (with free mods and a few other cheap ones you get like 155) then with the cam and porting stroke it and bore it 30 over this will give you a 3.2 or so and will give you probably 200 (this is if you replace the valves and everything else) A/C delete helps and if you have smog stuff pull that and it will help more, then rebuild the tranny good and headers for the cam and a good exhaust, a high flow y-pipe REALLY helps.

If you have a cam to match everything and not just a regular v-6 cam from Summit then you can get up there fairly quick. You can also get high performance aluminum heads but I do not know how much they cost. If I added the heads, fiberglass hood, aluminum radiator, my car would weigh less than 3,000 pounds and that really helps in the quarter.

Yes it would be cheaper to drop in a v-8 but I am in A&P school and work and a few other things so my car can only be out of commision for a very short time LOL

Tom thanks for the info, unless I found a cheap turbo kit out of a feiro it will stay N/A but something tells me adding a tubo will be a pain. I can't seem to find 2.8 NOS kits, some 3.4 though.

BTW Tom, when I changed my fuel filter I noticed it came from the factory, It also still had the factory tranny and rear end fluid.

AND THE PREVIOUS OWNER WORKS FOR CAR QUEST!!!!!!!!!!!

 

300 FLYWHEEL HORSEPOWER?????

your dreaming

do you understand the difference between rearwheel and flywheel HP?

how are you coming up with these exxagerated figures?

are you claiming 5HP for every mod and adding them all together?

 

stroke it and bore it 30 over this will give you a 3.2 or so and will give you probably 200

a stock 3.1 makes 140 HP.......boring a engine .030 over isnt a power mod.....its to clean up the cylinder walls to ensure proper ring sealing

here's the easiet a/c delete......just dont use it.....a/c doesnt rob power when its not on..........the compressor simply acts as a idler pully when the a/c is not on........so i fail to see where your comming from, yet again

your not going to see that much of a gain from removing your smog pump

trannies dont give you HP

keep in mind your still using the stock valves in those heads, which are going to be a major restriction

 

call around, I bet there is a TC shop in your town that rebuild them. There is really nothing to a TC all they do is add or remov a shim and its a higher stall. Localy rebuilt one sohuld only be abour 60 bucks. and it wont be any better or worse tham BM, TCI, Summit a TC is a TC.

 

Who said I was using the stock valves or even the stock heads????

It is not hard to get 200 I am pushing 150 something and thats with ignition and the free mods and stock exhaust, there are stroker kits out there that get you 180 with that and the extra parts and with a mild cam.
As far as I know 86 cars did not come with smog pumps
Yes I may not see that many gains with a few things but that A/C compressor weighs quite a bit ya know
End of discussion before this goes down hill

 

According to my GM book, an '86 with a manual trans got the smog pump. Automatics didn't- go figure- but I'm not complaining! But this also tells me than a manual-tranny'd '86 (and therefore, every 2.8 and 3.1 afterwards) can pass emissions without a smog pump.

 

I doubt my car would pass LOL


Hey Tom, have you ever had problems with your Idle?? As in it sounds like a big block with a monster cam but much worse and no power through 1st gear????? A few people thought it was the IAC so I have the TB pulled and I am cleaning all that out and checking the wiring. There is also a ton of black suit in there like the motor back fired a few times through the TB

 

did you have your car dynoed?

 

I'd recommend trying ZEX for 55-75hp.

 

Yeah 150 with the stock exhaust and a bad bending job and pulled air filters. The engine was not even runing the best.

Stock is like 140 145 right????

 

how about you post your dyno sheet then?

otherwise i call

 

what 150hp @ the wheels ???
with just free mods???

what are ur mods...

 

i'm curious to know what your mods are too, and what's so fre about them???

stock 2.8's didn't have 140-145 stock!!!!
my 3.1 has 140 stock and that's from gm brand new.

 

obviously he means flywheel 150hp, not rear wheel, but a dyno has probably not been done anyways.

i don't think a tb bypass and a couple ignition parts will give you 15 any kinda hp.

and the 2.8's were in the 135 range, dunno what it'd put out 12+ years later.

would rearwheel be about 112rwhp new/stock?

 

I do not keep dyno sheets nor do I keep time slips because its nothing to brag about, I did not do the TB bypass and when I say free mods I mean things like cutting the air boxes. I also have done a few engine, fuel pressure, intake, and exhaust mods along with aluminum wheels (less weight to turn compared to the stock steels) and a few other things.

Lets end this guys before it turns into a BS war
