upgrades?

[faubs]

im not sure what i should get for my engine? i would like an upgrade. i already have a k&n air filter and new headers. does anyone no what other thing i could get? (not being extremely expensive)

[dmbprep69]

Ummmmm well first of all where did u get headers??? Unless u had them custom made for yourself nobody makes headers for the 3100... Anyway, next u could get a catback, but that has to b custom made as well. I have one that they made me at the local Monroe, and it only set me back about 300 and I have 2.25 piping. Anyway, yeah I would say thats usually the next step.
Peace,
Andrew

Get a CAI, just buy a Civic one off of Ebay, you can get them for under $50.

[1992grandam]

Theres actually quite an aftermarket thats getting going for the 3100. www.milzymotorsports.com or it could be .net i guess i dont remember. But they now make headers/cams/an actual cai for the 3100. also RSM makes pnp'd intake manifol;ds and throttle bodies. If you really wanna go all out you could just swap in a 3400.

[Azrael]

Milzy doesn't have the headers made yet to my knowledge. I was part of the original group buy in the summer to get them made (I still have my money in it) but it fell through in the end.

Personally I'd avoid RSM's porting work. You could let a monkey go nuts with a dremel and he'd still do a better job although their 62mm throttlebodies are good.

www.donkeypunchperformance.com is another site with good stuff to get with great prices.

If you wanted to keep the 3100 you can swap the stock heads, intakes and throttlebody from a 3400 for an extra 15-20HP.

Might have to throw that in my list. Anyways why is it that it gives that additional hp??

[1992grandam]

The 3400 is basically the same engine as the 3100 but its bored out, has bigger heads/intake manifolds and TB..

[PontiacGT]

so the same pistons work with the bigger heads? You say bigger heads you must not mean cylinder bore though......

[Azrael]

The 3400 top-end swap gives more power from the bigger intake and exhaust ports, bigger intake valves and larger exhaust manifolds. The throttlebody is an extra 4mm in diameter for an extra 46 cfm of airflow capacity. Theoretically you should see close to the same power as the new 3100's with this swap which are rated at 175HP and 195lbs-ft of torque stock (10lbs-ft shy of the 3400's ratings).

you can also bore the engine out .30 over. i don't kno what the 3400 bore is but it's prob not .30 over.

get a stage 1 cam for it. that'll give you an additional 30hp and it's not overly expensive. and also get the exhaust headers from milzy. for 400 bucks you can get uncoated or coated for 600. that's not overly expensive. and with that you can get high flow cat and 2.5in piping with aftermarket mufflers.

and i'd stay away from that cai that they have. i talked to them a while back about it. it has the ribbed black tubing for the tubing. the ribs reduce your performance because air gets trapped in them and doesn't flow to the tb effeciently. mike disagrees with me and says there's no difference but i've seen dyno's that have proven the difference. and i kno from talking to bunch of mechanics. your better off getting the civic intake from ebay or buying the flexible tubing from summit racing. that's what i'm doing. about $50 bucks but it can withstand an ungodly amount of heat making it ideal for cold air intakes and exhaust too.

[voyager]

tranzgenic makes the best CAI for your car IMO.

i agree that smooth tubing is better than the ribbed stock stuff.

the 3400 heads also have roller rockers ( well sort of ) which operate with less friction, another bonus. the big thing is the increase in flow in the intake manifolds.

milzy didn't actually fab headers, did he? you're kidding??? because i seriously want a set if there is a set to be had.

[voyager]

i don't believe you've got headers. perhaps you're mistaken.

[96GreenGaGT]

he must have not followed through on it. sometime soon we should see them though. still waiting for him to make them. when i posted that i had the knowledge from him that it was a go... but apparently it's not... i don't kno have to email him and see what's up. cus i seriously want a set too in the future. unless i do a 3400 swap....

[RisingX2004]

So what years of a 3400 top end swap could i safetly put on my 96' 3100 without having to do all the grinding and other modifications to the intake manifold? Is that possible?

[Azrael]

The 3400 heads are the same from 96 to present as well as the 2000+ 3100's. If you're not changing heads you'll want the lower intake manifold from a 00+ 3x00 otherwise it won't clear the rockers. All 3400 and 00+ 3100 LIMs require tapping the coolant hole to 1/2" NPT threads. A 96-98 3400 upper intake manifold is the easiest to work with since the EGR port is vertical like your current 3100. Some 96-98 3400's found in minivans had UIMs with no lettering since they had engine covers.

[RisingX2004]

So I could use any 96'+ 3400 heads and LIM & preferably a 96-98 UIM, 3400 t.b., tap the coolant hole and bolt it all on? Just wanna make sure before I do anything to my daily driver.

Well even if you do a 3400 swap you'll still need those headers (if you'd still want headers that is), because the problem with the 3400 headers isn't that they don't bolt up (they do I believe), it's just that they won't clear the firewall on older GAs.

To make it easier, just get everything from a 3100 LG8 engine (00+) and you'll be fine. Even if you get a horizontal-mount EGR LIM, I'm pretty sure the 96+ L82 EGR still fits fine, it just sits sideways instead.

[Azrael]

You can use the 3400 exhaust manifolds but you'll need to have a custom downpipe fabricated. There's limited space to work with and some exhaust shops may not want to do it.

[RisingX2004]

Cool, thanks

what? I thought he was talking about doing the 3400 swap?
how come you're telling him to get just 3100 parts?

[adam4tw]

I saw someone mention the stage 1 cam shaft... if I were to get one would I need a shop to install it or could I do this myself?

No he [someone] was talking about swapping the UIM/LIM and TB from an LA1 on to his L82, and he was worrying about getting the right parts from the right 3400s to fit. So I just said he might as well get the parts from an LG8 3100 because they are the same as the LA1s, plus they'll keep the "3100" name on the UIM and (from what was said about the variances of LA1 parts by year) it seems it is more likely to get everything that will fit, if you get it off an LG8 instead--save time, hassle and head scratching.

The cam has to be pulled out from the passenger side of the engine, and because of the fender, it requires the engine to be removed to get the cam out. I'm not sure if it's possible but if you could lower the transmission+engine a few inches you could probably pull the cam out through the wheelwell too.

[96GreenGaGT]

i have heard of people pulling it out through the wheelwell but don't know how much difficulty that is compared to just lifting the engine out through the top.

[PontiacGT]

from what I hear, our engines don't come out the top well, it's easier to drop.

[95CombatGA]

MMS 3100 Stage 1 Powertrain Control Module (PCM) is it worth it to get this? i havent heard anyone talk about it. do u have to run premium gas?
