Where are you pulling that 250HP from? You have a catback to? Seems you do according to the redline forums. What kind of catback? Have you had the car on a dyno? Add all those things and you probably will get to around 265-270. First thing I would do is get some 60's so your safer, and add a heat exchanger........ if you want to spend less find a used Cobra, they go for around a hundred shipped, slap that on there. THe injectors will probably cost you around 180. Then go with a Clear Image header/downpipe/high flow cat https://www.cobaltss.net/forums/supporting-vendor-deals-group-purchases-133/new-stainless-steel-header-sale-124358/ They are actuall on sale now, I paid 530 something for my setup (all stainless steel), wich will be here in a week or so..........the other guys stainless steel combo's arent shipping. You can save a bit of money going with non stainless steel if you dont care about rust in a few years.

 

yeah i have aem,b&m,power slot, hawk pads, b&g springs, 18's, vibrant cat back, lighting force 42's, intense 2.9, dyno tune by smg. duel a pillar gauge pod.

everything that ive read suggests that going smaller than a 2.9 is just retarted..... you should know why.....

well thanks to all that threw in there 2 cents. not sure if i want to spend all that cash for about 20-40 hp give or take a few.

im looking at about
180ish for injectors
200ish for tune
500ish for header
100ish for h/e
200-400ish for meth

so basicly looking at $1000-1500 for that little HP..... um no thanks i think im better off saving and wait for a turbo kit, tvs, or zzp to come down off there twin charge kit......

thanks again..........

 

you gotta pay to play no one said it was cheap

 

depends on how you look at it........


A high flow header/downpipe will only net you 15 or so HP from stock trim..........but what does it average across the board.........I am sure it will knock a few tenths off of the 1/4 mile time.

If you planned on going TVS at a latter date, all of those mods will help with the TVS on there also. Although I personally think the TVS is a junk mod dollar wise. Its the easiest to bolt on, but in the end you dont gain more than the turbo setups, and you end up with the same heat issues.

I have had a 2.7 on my car for a few years now, no heat problems, and the blower is fine. I dont constantly beat the **** out of the car like many idiots do though.

Atleast get the 60# injectors and tune for them, if anything to make the car safer to drive. ALso the 7000 RPM redline is important when your at the track so you dont have to perform a 3-4 shift at the end of the 1/4. Plus the car is still making power from 6500 to 7000 RPM, power your missing, and again if you ever plan on going TVS or Turbo, you will need the 60's.

The heat exchanger will help with heat soak. It does not add HP, it keeps the HP you have there. After a few pulls you will feel the difference as your ITA2 temps go up. Its another cheap, added bonus to keep your car safer.

 

ill take part donations...... or a sponser...... or cash if anyone wants to give me some of that.......

 

hmmm seems like a educated opinion......

 

lol....yeah..extremely educated...I'd like to know why the tvs is such junk....hmmm....bolted up with/toys and tune is what.....close to 350ish whp with the stock 3.1 pulley for just over 2g's. Its what almost 4000 of the hahn kit...which is a respectable kit...but its twice the cost. Apparently he also doesnt know how much more effecient the tvs is either...but what do I know.......or you... hehehe...oh wait I forgot..you have that setup....

 

Well there are some things that aren't being accounted for...such as: when you go with a turbo setup or swap in the harrop you need supporting mods otherwise likely DOOM. The factory clutch only supports around 330hp and who knows about the engine. As well...probably want to go for better axles as well.

So with any of these kits you have to add the cost of those items unless you already have them.

Decent clutch/flywheel setup 800+
Axles 300
Engine build 1000 (?)

As cool as it would be to put down close to 400hp, it's going to be mad money. I mean, is putting 5k worth of parts in a car worth 11-12k, worth it? How many people have tried running these setups long term on a stock engine? For me...before slapping the harrop on, I'm going to wait and see what has happened to the guys who are running it a year from now.

 

HEY WAD, you fail to read the part where I say I PERSONALLY Think..............so calm the F down. Its my opinion, I think a turbo is a better way to go, ...................... as I said I PERSONALLY think.......and its still doesnt seem to be as effiecient as the turbo setups........again IMO.........
and I have yet to see actual dyno results, of a Harrob, not running meth, pushing more than 330HP. I have yet to see a turbo setup not doing that...........and yes the Hahn kit is expensive as hell, but it shure seems to have a hell of alot more in it now doesnt it. I may buy the Harrop, its the easiest way to go......but its not the most efficient........


.. thank you, please drive through.....

 

HuH, other than SMG eh? Thats wird because the fastest lsj @ newengland dragway was build by him. That is also the only running turboswap lsj in New England.

I know the owner of SMG well. I know what power you really made. I know why he lowered your redline. And I know how you can make power like me.

But, lying and refusing to spend money is not the way to do it.

He will turbo your car too. But, as many have said you have to pay to play. Then you can look for a real 300+ car

 

HEY WAD my reading is quite fine.....and dont think I was really that pissed off. But to go and say the tvs is a junk mod I think is alittle far fetched. Of course the turbo is gonna be a better way to go for some serious power...but like I said its twice the price. Also the tvs is not more effecient than a turbo...but it is really really close. Of course meth will add alittle more power...but its best benefit is for the lower IAT's...but I'm sure you already know that. Unfortunately if you run high boost out of a supercharger....high heat will always be your problem. For $4000 you better get alot with the hahn kit...it would be pretty disappointing if didnt wouldnt it? Like you said its not the most effecient...but its alot more effecient to make 300+whp than the stock M62.

 

WHAT THE **** ARE YOU TALKING ABOUT??? ARE YOU REFERING TO ME????? i havent lied about **** ******. WHO THE **** ARE ZOU TO CALL ME A LIER!!!!! want to see my dyno print out you stupid ****??? unless out law dyno screwed with me and faked my dyno numbers i dont see how i was lying?????? oh and by the way why did he lower my car id sure like to know?????? all i asked was there another garage in new england that works on lsj's how does that make me a lier???? before you make ignorant comments have a clue what the **** your talking about bitch!!!

HEY MAXIM YOU SIR ARE A DUMB ASS!!!!!!

 

I know....I did say with toys... Running any power north 300+whp is gonna need supporting mod no matter which system your running. Is 5k+ worth it in parts??? That depends on alot of things...do you love your car? do you plan on keeping your car for a long time? Sure if you put money into it now and then dump the car later....than of course its not worth doing. I personally dont plan on getting rid of my car for a long long time...so spending a few thousand isnt that big a deal to me. Plus think how much it would cost to buy a car that came stock with 400hp.....


Well SMG is known to be a good shop for the new england cobalts and ecotecs in general. I've heard nothing but good things. Obviously something has happened and thats why you want another shop. I dont know why...but I personally wouldnt have my car tuned by anyone else other than fred at smg.

 

Well i would free up everything before and after the motor first, intake, throttle body, port the blower, then get the header and downpipe. SO bascially only restriction in air before or after the motor is the intake manifold which doesnt have a solution.yet... Get the 60's heat exchanger and tuned with all that and i could see 280hp.

 

I'll agree with that, and honestly for the ease of installation, its probably the mod I will go with next March when I purchase the next mod.............I am perfectly happy with around 300 to the wheels and dont see me ever pushing much farther than that, if I feel the need for more power, I would buy an old Fbody again, and build the crud out of it, and not have to worry about something thats not a daily driver. Perhaps saying it was junk dollar wise was harsh, but the twincharge kit isnt much more (3000 compared to 2200, and offers I think, more potential. (That is when they release it for self install.) Juding from their current pricing, it will only be 3000 for the base kit, and HPT file. We will see how it hold up as more people get it though.)

 

Agree to that....the twin kit does look promising....but the tuning on that kinda scares me alittle. I think the harrop swap would be much easier and probably more realiable than the twin kit....maybe it wont...who knows....I would definately have to wait to see more people with that kit and how it holds up. I think the tvs would be my first big mod...sell the current supercharger and the price the harrop wont be as bad...if I decide to keep my car much longer..than turbo will be the next step...but thats many many years from now...lol

 

Obviously something has happened and thats why you want another shop.


......ummmm NO!!! when did i ever say "something happend" other than fred being a pain in the ass to get a hold of SOMETIMES ive had no problems. i was just wondering if people are getting work done anywhere else. i like to keep my options open. therefore the reasion i asked if anyone new of a good shop in new england that works on lsj's other than SMG..... everyone seams to go to SMG..... you know what they say when you assume something...... YOUR AN IDIOT!!!! if i was unhappy with SMG would i be sporting there sticker on my front bumper????? probably not.....

anyway to the people nice enough to help me out with reasionable suggestions thanks. i have all the info i need and wont be checking back to this thread....... unless, someone wants to explain what i should be looking for in a cam and help me pick out one lol........

 

folks here need to chill. were all on the same team here. Fred at SMG is awesome, but it is true he can be hard to get a hold of. Im keeping up with this ZZP twin charge kit...seems interesting alternative to the tvs.

how about you NE folks take your agression out at the NE dragway on 8/30. Check the regional thread for all the info. Lots of lsj will be there.

You need to settle down chief. Thats fine if nothing happened...but SMG is the only shop of I know of that has any real time with the lsj's. I'm glad your not coming back to check on this...its people like you who trash these threads and have to flip out and resort to foul language and name calling that give this forum a bad rep. Now on a good note...good luck modding your car...and I'm glad you've found the info you need.

 

smg is great dont go anywhere else youd be losing hp and great custom work... with that said. get a good cai bigger tb port the blower. 60's meth big heat exhanger and open up the exhaust.

i got a 3.0 header meth and i made more hp than you with freds tune so that shows the meth helps out. i ported my blower got a cai and changed mufflers so now ill be over that mark too. and i didnt spend a ton of money
