Performance parts for n/a dsm's

[Thunderskull]

I'm cool with it. I was just so stoked about it, it was kind of a letdown when it wouldn't fit. That's ok though. The fella at Punishment was very cool about it over the phone, and they're sending me another one. I'm not sweating it. This is their first set of headers, and there's bound to be problems. I kinda figured they didn't have a test car with powersteering.

It's all good.

i also give props for punishment personally finding this thread and posting to set things straight. not may people would do that

 

[Thunderskull]

Agreed

Now I'm off to buy a new 02 sensor. It was on it's way out anyway. I was surprised that it didn't run hella rich when it died though. I expected it to run rough with black smoke coming out the tailpipe. I did notice a power drop though.

Sorry to hear about your problems thunderskull... At least your brand new engine swap that has less than 900 miles on it didnt just seize.

The friggin oil pump failed and the engine locked. I guess i'm doing my 2.4L conversion a little sooner than I thought...

 

[Thunderskull]

Ouch. I hope it had a warranty. That's why when I do my buildup I'm starting from the bare block. I want to make sure everything is new and installed properly. I was just going to rebuild mine, but this way I hope to avoid any major problems down the road.

I'm not sweating the header thing. Nobody that even saw the pics caught the fact that it wouldn't fit over the power steering pump. They're going to replace the header and do it properly. It'll just be a couple more weeks before I get to install it. That's fine. I'm getting tires and suspension parts this weekend anyway. Besides, I'm still having fun with the translator. As soon as I get my cable for the logger, I'll do a translator tuning guide for the n/a car.

im convinced your rear wheels dont PUSH the back of your car to keep it very nicely from slipping out. YES. Again if front wheel drive was the best way to keep your car stable, then rally cars would be front wheel drive. Unfortunately...for you.. all of mitsubishis rally cars are all wheel drive...hmmm makes you wonder which one grips better doesnt it? :thumbdown

You don't seem to understand why AWD handles better. The rear wheels pushing make them MORE prone to slipping. When power is being applied to wheels, you are increasing the slip angle of said wheels, and also increasing the probability of it breaking loose. Basically, part of the rubber in contact with the road on the outside of the turn moves faster than the inner portion of the contact area. As you apply more power, this increases until traction is broken.

Now, here's why AWD handles better. You're cornering hard, and the power at the wheels is increasing the slip angle. Sensing that one(or more) wheels are starting to move faster than the others, power is transferred to other wheels. So now, that wheel that was previously losing more and more traction has power taken away, which causes the wheel to slow down, and increase the traction again.

If your theories about why AWD handles better were true, FWD would almost always result in oversteer tendences, and RWD would almost always result in understeer tendencies. This is the opposite. That being said, this can be reversed with suspension tuning, be it aftermarket or from the factory.

As far as stability goes, AWD doesn't really do *anything* for stability. The car's stability is determined mainly by suspension. You can have AWD till the cows come home, but if you have heavy body roll, you will handle worse than a FWD that handles very flat.

Thank god, someone who knows what the hell they're talking about!

he thunder does your dsm rev faster with the new sensor? i drove my dsm yesterday for the first time in a while and it revs so slooooow. but my buddys 1.8 revs faster. i knoticed that 1.8s dont have a MAS beforethe filter. i knoticed the revs going so slow after driving my mr2 for the past week or so. that thing is at 8k WAAAAAAAAAY faster than the dsm.


i hope them headers show some nice gains. im looking for a new 1g nt, since my gf has backed over a few rocks and damn near fried the clutch. my dsm is lucky to still be alive. (she is using it to learn how todrive a stickk.)

Yes, opening up the intake does wonders for throttle response. It's one of the many good points of owning the gm maf.

 

[suicidal2af]

limited slip differential combats the inner tires breaking traction..which my car is also equipped with.

Yes, but an LSD does nothing to combat weight transfer. A car with a well-tuned suspension that has very flat handling will still outmaneuver you. When you turn hard and all that weight is transferred to one side, the chances of your slip angle turning into a slide angle rise exponentially.

That said, driver skill and understanding of how and WHY your car will react to different situations is probably the most important part of handling. People who get cocky and think that "AWD = HANDLING PERFECTION" are the kind of people who end up smashed into a tree, or turned over in a ditch. Or twisted in another car's wreckage.

 

[Damn 2nd Gear]

now i want one sooooooo bad. but buying parts for 2 cars cost more than 1 car .


MR orientated cars seem to handle better in most cases just harder to drive. its alll about weight distribution. but thats on cement. my mr2 will never see a dirt track, its a bit too tail happy, until im more experienced driving it.

If I was a mod I'd lock this mother f*cker, you know why, take a wild guess. SHUT THE F*CK UP or start a new thread and bi*** about this senseless awd vs fwd BS in there. I dont wanna here it and Im sure the people at Punishent racing dont wanna rumage through all that garbage. No, they want to read insightful posts about their products and our idea's. Shall i call in the Calvary?

 

[Damn 2nd Gear]

i wanna hear more on them parts!


but i did learn some stuff about how AWD works in rally/drift

 

[polaris956]

I drive the 1.8L and want a lil more performance. I know there are many others out there too. I emailed punisment about possible headers for the lil engine that could. So how bout you people stop bickering as usual and discuss motors and not dirt... but thank you for the info, im not a pro like some. What kind of engineer are ya ralli art boy? I wanna go into architecture field... and i really like to go off subject!

 

[Damn 2nd Gear]

hey my engine got as much dirt as anyone elses!

yea the 1.8 does need some performance parts. i think there is more powerin that thing than we are seeing. this dude i know has a 1.8 with just a filter nad intake pipe. i never realised tehy didnt use a MAS to choke the intak. it sounds mean as hell too. im thinking some higher compression pistons and a good cam would work wonders. you guys REALLY need tobe able to rev higher than 6k. i raced the same 1.8,thing is mean off the line but chokes on the revlimiter.

Cams are a good idea, but pistons no. I dont think that we 1.8L folk wanna mess with the factory engineered pistons. Those were engineered by people much much smarter than me and many other people on this site. Although, if they were smarter they would had given the damn engine more power!!!

GIVE ME A CAM! that'd be cool, and valves that dont tick like hell

I've hit rev limiter many many times. When im mad, rev lim is my shift light! j/k

 

[Damn 2nd Gear]

actually hogher compression and stronger valve springs anda cam that breaths to 8k would help u tons. hell even 7k would make a world of difference if your cams allowed it. factory parts are far from perfect, thats why companys like AEM and HK$ are out there building parts specifically for racing, and they are built tofactory specifications and in alot of cases are stronger than factory parts. its just $$$ to have a shop swap pistons and rods. a 10:1 c/r would be a good step




valve tick? sounds REALLLLLLLY bad.

my lifters tick when i need an poil change, only then now. its weird.

 

[Thunderskull]

Ok, I didn't want you to think I had forgotten about this thread. I received the new header this past week from Punishment. It's going on today. I'll post my impressions tomorrow.

 

[na90dsm]

lemme knwo how oyu liek it dude. also pics would rule if you can get those. im very interested to see the outcome of this product

Hey did you get them put on yet and have any pics and a review of somesort they are my next purchase

 

[Thunderskull]

Not yet. I did examine the header to see if this one would fit, and it looks like it should fit just fine. I was going to do it on Sunday, but I wound up getting too busy. I'm going to try and find time to get it on there in the next couple of days. I'll post results by the weekend.

 

[samuraitekno]

punishment... when i click on your website to look at the header i dont see anything that says $185 all i see is upwards of $300 ... let me know what is up with that... how do you get a $185 header and what does that include?

 

[na90dsm]

pacesetter is abotu 185 and i wouldnt get it again if i had no other choice. i ported mine and it did its job but its not stainless number one, so it rusts very very easily. and 2 i had to fix there shatty welds by porting it to match the head ports.

im gonan get either the extrememotorsports header($450) or the stainless punishment header. borla had a 4-2-1 header but its being discontinued, machv has some left but at that price (also $450) its not cheap. borla is also stainless btu i have had bad experciences with borla products. they crack a lot and it doesnt take much.


IMO there are 2 choices, the extreme motorsports or punishment. granted i never cracked my pacesetter and it was a 4-2-1 header, there is better otu there

 

[Mike1992]

my pacesetter is cracked all to hell and ive had it rewelded 3 times now :thumbdown

 

[Thunderskull]

Well, I'm installing the punishment header now. Finally! I'm having lots of problems. It still doesn't fit right. I had to shave some material off the plate the bolts go through on the head to get it to fit around the power steering bracket. I also had to unbolt and bend around the oil dipstick. To top it off, the bolt hole on the far passenger's side was off. It didn't line up so I had to drill it. I'll let you know how it performs, but I should've spent my money on an armor coated pacesetter header. It would've been less of a headache.
