well guys i think im going to go all motor car. nothing extremely crazy. just want some more hp this wont be happening till about next summer. im just going to start to put together a parts list. i wanna know what you guys think? i just dont wanna boost it.

 

TTR or HAHN sheet metal intake
2.4 Tb ported and polished
ported and polished head w/ knife edged ports, also shaved 0.020" for raised compression
78lb valves w/ better retainers
ZZP long tube header
2.5" exhaust
SS/SC cold air intake
Tune

If you have a fair amount of mechanical skill swap in a 2.4 crank and rods, and have you pistons bored 0.20 over

 

And if that's not enough power, look into a wet shot nitrous system.

 

i was gonna take it some to get done. i wouldnt mind doing it myself if only i had help lol. but how much hp would i be making?

 

Do not shave the head on an Ecotec, GM doesn't recommend anything more than a simple buff to clean and true the head.

A sheet metal manifold will make you lose power, the runners are way to short since they are designed for boosted cars. The 2.4LE5 manifold is a good option tho.

A few bolt-ons and a tune will really wake the motor up tho, so I would start there.

P&P head will make a huge difference if it's properly done, on a all-motor car the head is where all the power is made or lost.

 

yeah. its hard cuz i dont know much about this. right now im going to get the 2.4 mani and tb and then tune. i already have injen intake. badmab header zzp down pipe and magnaflow catback

 

You will be lucky to get to 200whp

 

Other than that, balance shaft delete should free up some power. Then you are on to internal work tho, I don't believe they make cams for that motor, so you are kinda limited there.

 

yeah im gonna wait on the motor build lol

 

there is literally nothing here besides the tune that would benefit the car

 

i need a 6 pin 2.4 tb

 

I meant to do so to raise the compression ratio. Bumping it to about 11:1 should yield 10hp or so and still allow use of pump gas.

 

shaving the head does work well on the 04 2.2s IDK about the LAP

 

wut lulz? i know someone that has pretty much an identical build on without a longtube and no sheetmetal intake .. (which might not help i'll agree with that)

and put down 172 with no tune on an 04 2.2 throw some cams in the head though and it'll make for a more interesting build

 

id love to see you do this Royce. i someday want to do an All Motor 2.4.

 

GM doesn't recommend shaving the head, to raise compression or not they say don't do it.

 

Well they get paid a hell of a lot more than i do, so I'll take their word for it. How about a head swap from a 02-04 Cavalier or a 05-07 Cobalt and tune out the vvt and run bigger cams.

 

im sorry ill rephrase. ss/sc intake will not fit. LAP already benefits from the LE5 Intake manifold, so you cant do much more. A 2.5" exhaust will release some HP but not enough without a different DP. Depending whether your LAP has SAI, Long tube headers will not fit unless you have a custom DP made. LAP and L61 have been proven to not benefit from getting your head shaved or ported and polished. Prior to my LAP, I had a fully bolted on L61, and although it had slightly more HP than a stock one, it didn't really benefit from it. Springs and retainers are only necessary if you Cam it, but there are no cams available right now. Vince can tune the car, but i suggest waiting until you are fully bolted until then.

 

like i said i dont know about a lap but i know some na 03-04 2.2s with PnP and shaved heads that make more hp then then 06-07 2.2s

 

ttr intake manifold - 500
2.5" exhaust - 350
2.5" dp - 200
badmab header - 160
2.4 tb port and polish - 150
2.2 intake - 200
stage 2 cams - 400
valve springs, valves, retainers - 400
tune - 250
total price - almost $3000
total power - less than 200 whp more than likely

not worth it...

 

You can see gains upwards of 40bhp, with a full bolt on/cammed L61, with a ported head over a stock head.....so I'm not sure what you are talking about.

That is basically what I have done to my motor, and its makes 169whp.

Without a ported head, and some work to bump the compression you will not see 200whp.

 

so your just proving my point?

$3000 for 169whp, go turbo or supercharged

 

some people dont do it for all out power

 

That intake manifold wouldn't help, it would make things worse.

The headwork is only useful if you're capable of using a lot of RPM range...well over what you're using currently and on top of that, you def need to have sufficient tuning to even take advantage of any of those modifications.

To the original poster, how much money are you looking to spend overall? How much power are you estimating to make?

 

^ This, i Figure i can build my LE5 to over 200 Wheel for about 1500-2000. costs theh same for an S/C kit and i could make more, but i like the N/A route. i fell its more respectable to build a 200WHP all motor 4 banger, FI only becomes impressive on these motors over 400 Horse, IMO and i dont have the money to take it that far
