You're going to hate me for this but.. What mod next?!?!

[letthiswork1]

Hey Guys,

I hate the 'what mods should i do to my car next' threads but.. Im really torn on what to do!

So far i have the basic Cat back Exhaust with a Mace CAI.
I have about $2200 to spend on my car. I am thinking of Getting some body work done e.g Tint windows, Lower car, new front Bumper..

But as far as perfomance goes im torn on what to do.. I am thinking of getting Pacemaker Extractors and Maybe High ratio Rockers..
What is going to be the best perfomance? Keep in mind this is a project for me.. although also my daily drive...

Its a V6 VY 03 Ute.. done 180,000km

On a side note - How much is a tune??

[VT_SS]

Is it a V8 or V6 and i would start with finishing your exaust first.

[letthiswork1]

Sorry completely forgot to add that.. its a V6

[hN!]

Roller Rockers 1.9.1 + Full exhaust Best bang for your buck in my opinion and dif gears if you wanted.

[letthiswork1]

What would you say is better? Roller rockers or diff gears? Car is auto btw.

Thanks guys

[Calaber]

Diff gear change can improve acceleration at the expense of top end speed in each gear. It's really just a compromise but if you want better acceleration through the gears, this is the way to go.

Changing engine components like rockers can improve performance slightly but with the comparitively crude design and low state of tune of the standard V6, the improvement is not as noticable as changing gear ratios.

[monkeys437]

For that coin you could forget about body mods and go Second hand LSD and diff gears, Mace rockers and pacemakers.

[letthiswork1]

Do you know how much diff gears cost and to install? Same with a tune

rockers will gain 10-15kw plus buy a MACE chip for $120 at the same time, do the hi-flo cat (I paid $750 for mine) and extractors later as there very expensive for little gain maybe 5-10kw. diff gears will cost you anywhere from $400 bucks at a wrecker to $2500 for a full diff rebuild with no pwer gain just more wheel spin down low and a lower top end speed plus high rev's on the highway using more fuel.

Vy's don't run a seperate Memcal so he would need to get it tuned in person, or get a replacement ECU sent out; Unless that's what you mean.


OT: Roller rockers would be the go to get best bang for buck and not have to give up your fuel economy. If you don't care about fuel economy, I know someone who can build you fresh tight LSD, brand new better graded bearings, seals etc for $950.

I'm selling mine if you're interested also, I got it from the same guy and I've done about 4000-5000k's on it.. So pretty much ran in.

Offer me a price if you want, depending if you're in VIC.

didn't know that I was able to chip my VT just assumed it would use the same computer as its the same engine's

[letthiswork1]

I am thinking i will go the with Exhaust and Rockers... And gears too..
Excuse my ignorance but what is the biggest upgrade with LSD? isn't only a benfit if my wheels are spinning?

[menace2sobriety]

A couple of things that I have found is that Exhaust - will give you noise and some extra power throughout ( maybe some drone around 2000rpm depending on the system ), Rockers - some mid-top end OOMPH ( the VY ECOTEC V6's aren't really happy HI revvers though ), LSD and Gears - off the line PEP and some squat, acceleration will be improved - probably the best bang for buck you could do, eg you could loose about a second off your quarter mile times with decent diff gears but maybe a few poofteenths off with all the others, a tuned PCM from MACE will make it more of a daily pleasure to drive with more responsive power throughout and quicker gear changes - do the other mods before this unless you have an OBD1 cable and the software to modify and re-flash the VY bin files, also the inlet and plenum insulators are not too bad for the price, better down low torque and response, but it all depends on what you are after a racer or something with looks, if you are after a racer why don't you keep it as a daily driver and put that coin towards something with potential or just chuck some boost down its throat, if you are after something that looks pretty just slam it on some mags and add some visual luxuries

IMO since you seem set on spending money is Finish the Exhaust, ADD some Rockers and fit an LSD with new gears to suit - ALL AT THE SAME TIME, that way it will give you the feeling of money well spent

[Not_An_Abba_Fan]

Exhaust is a good bang for buck, but the down side is that you will put your boot into it more to make more noise, thus using a shitload more fuel.

Having said that, I can send you a set of Wildcat extractors that fit straight up with no welding for $385. Leave the factory cat, as a high flow will only make more noise. If you want to spend the extra $100 or so on Pacemakers, will you get an EXTRA $100 worth of performance out of them...

I currently have a Cat Back and to be honest i think the noise turns me off putting the foot down! My fuel economy has been so much better since!
I am pretty set on the Pacemakers i read into other extractors and everyone seems to really rate Pacemakers.

Thanks

LSD will give you heaps better traction off the line than a standard diff. No point doing mods if it's just gonna give you wheel spin off when you floor it from a rest

[letthiswork1]

To be honest i can't see my wheels spinning off the line because i have no intention of dragging :P. I just enjoy the nice delivery of power!
LSD would be handy up hills in the wet though! Jeez!

I think ill go full exhaust, High ratio rockers and Gears for now with a tune if in budget.. LSD will be next ^.^

@menance the inlet and plenum insulators look good too but just don't seem worth it right now

[menace2sobriety]

If your just going for driving experience and not setting it up for dragging or power, just get a shift kit and tune and leave it at that

[Not_An_Abba_Fan]

If you don't want to spend the $150 or so on the spacers, why spend that much extra for no additional gain on Pacemakers over any other brand? You are talking bang for buck, Pacemakers aren't good value when you are comparing $$$ spent against any gain.

On a street car, all extractors will do pretty much the same thing. Pacemakers will give you maybe 0.3-0.5 secs on the drag strip, but on a street car, I would bet money on the fact you wouldn't be able to tell what brand of extractors you had if you didn't know. Fit 5 different brands on the same car and tell me which perform better, I bet you can't. You will be able to on a dedicated strip car, but not a street car.

Touche Fair enough aha... I will look into the spacers aswell. just have my heart on a full system.

Thanks for all the input guys has been a great thread

[richardpalinkas]

If you have 2200 to spend, there are used raptor kits on the raptor section for that price and will get you 13 sec quarter mile times. Best bang for buck where you are at

[Calaber]

The thing to consider with the LSD is that fitting a limited slip diff alone won't do anything for acceleration. The standard V6 ratio is very tall, giving good economy but slower take off. Get the ratio right - don't go too low. 3.47 seems to be the right one for overall compromise.

[letthiswork1]

Just ordered a new VY SS Front bumper for $800 painted.. Hope i'm not crazy.
Does $500 sound about right for the Lowering?

I am going to look into LSD.. im just worried about LSD in the wet kicking in...!

[Not_An_Abba_Fan]

lol...LSD doesn't "kick in", it's there all the time. Don't mash your foot down in the wet and you won't have a problem.

[Surfwagon]

I go along with the majority on this car.
Just fit some value for money extractors, any brand as they all outperform the cast iron manifolds and just leave your current catback.
A high flow cat for your engine will make 1-2rwk at best and really only make more noise so not neccessary.
High ratio roller rockers are good and will help the V6 breath and rev a little better although sometimes on older engines upgraded springs are needed or you may get valve flutter at the top of the revs which will actually lose you hp.
Probably the best performance mod (not nccessarily value wise) is lower diff gears and if you stay around 3.46 you should retain reasonable if not the same fuel economy as now but get off the line a hell of a lot quicker.
Top end will suffer although how often can you use top end on the street and how often would a quicker off the make and through the gears be of more use.
As for LSD I have way more power than your V6 will ever have without forced induction and I would much rather drive my car fast in the wet with an LS diff than with a single wheeler.
