Howdy all, as most of you know i own a 2002 Man Vrx. currently it would run early 15`s down the quarter and want to know what i can do to it to drop it down to a early 14`s with out putting a blower on it...

Any help will be appreciated

Cheers
Jason

Ego,

get a piggy back computer, and get a stage 2 top end from RPW.

u get lumpy cams and worked heads. would chew a bit more juice i would presume but it would haul arse. you'd be looking at 180kw at the wheels i would believe

Got any idea of what $$$ would be involved, piggy back around $1000 but what about top end..

Im just sick of mates with worked Skylines and VLT`s that think they are good when they just beat me and say im only running 10 pound boost. my reply is im not running any and you only just beat me you tossa... lol lol lol

ok unichip installed is $1100-$1200 installed

Heads with cams, maybe $2,000 give or take a bit

install would be $500-$600

go to it, u have until may to get it done cause thats when the 1st sydney auto salon is!!

Who cares how fast the car is for Auto saloon as i you wont let me race around in the pravillion will you...???

A 75hp shot of NOS would cost around $2,000-$2,200 tuned and installed. with that and the top end done will throw u into the 13's!

Dyno shoot out stupid! :nuts:

Yeah but NOS is bad for engine isnt it, i mean engine wont last long running NOS

The stage 2 top end would be good if it works...the only person I've known to have it done was Nick and it certainly wasnt anything to bother with...

I'd look at some porting and polishing, cams.

Depending on far you want to go, you could go and get lightened internals. I'd also look at a lightened billetted flywheel. These are things I'm looking at doing later on down the track.

You don't get more hp from that, but you get to your max hp zone much quicker, hence quicker 1/4 times.

The whole thing is getting to hard, just want something simple, might just look at some small blowers running 6-7 psi..

Why not start with some extractors and CAI. With just these two mods i managed 132kw at the wheels which is about 179kw at the engine. Im just about to fit a greddy e-manage.

If you want more then look at cams etc, stage 2 might be a little extreme but stage 1 would work nicely.

What are these things meant to have in KW at the wheels standard...???

Y do you say it's a little too extreme blake?? what are the side effects of running cams like these???

I dont know but crazy things are already happening, not long after i got it the badges starting falling off then off feel the spoiler, all i need now is for it to be growing 2 haeds or something.

On a closer inspection i think its to late as its already grown another exhaust...

are these covered under warranty...???

i think they run 120kw atw standard.

the arrects tzaboy are lumpy running arnt as good driving round town and use more fuel. But i would gladly give all that up for the extra power :D

ralliart cams is an idea.

Yeh good idea, but i thought they were impossible to get unless you owned a ralli art? CAI, extractors and sports exhaust should give you plenty of power :).

i remember the cams from RPW that nick got... nick named Diesel cams... they ticked sooo much! too bad his engine died not long after

Here in the US you can pick up a Nitrous kit for around $500.00. I know that would be a little more in Aus money but 2000?!?, thats just crazy. Installing and tuning them is not hard. Contrary to popular belief they are not any harder on an engine than any other power adder. They are usually jetted rich from the factory so people like to lean them out a bit, but usually go to far and blow it up. Or they try to spray for like 1 minute at a time. Where you should only go a 1/4 mile at the most while spraying. I even know of one guy here in the US that ran a 200shot (yes 200 shot) on his STOCK 3.0 6G72. It was in a car called a Sebring here in the US. He ran a 13.8 down the 1/4 with it. He did blow it up eventually but how long would you expect it to last pumping out more than double the stock power. Just my 2 cents... :cool:

They have the complex, forget about them. You can't go comparing boosted car's to non boosted cars.

Ralliart cams etc can be bought without owning a Ralliart. I spoke to Allan from the AWD Quadtec team and said anything can be purchased. Just go to a different dealer or chat to someone from Mitsu on here like funky_fresian_cows or revelstone2.

Have a think about if you want to stay NA or go forced induction. You could start with headers but then if you go a turbo, they will be redundant. Could be okay for supercharging though. The rest of the exhaust would need to be thought about.

You could go cams but again you'd need to think about NA or boosted. Higher compression? Headwork? Or even a twin throttle body arrangement?

Y do you say it's a little too extreme blake?? what

Accually he is pretty spot on with the 179kW flywheel figure. Stock VRX Manual will pull about 120kW ATW from 163 flywheel kW.

Thats a 26% drive line loss, therefore: 179kW(flywheel) - 26%(drive line loss) = 132kW(@ wheels)

:D

PS: that means my TF auto used to have 154kW at the flywheel (going on 29% D/L loss for auto) :cool:

Just letting you know what your options are...

Yeah i know. i thing its time to look inyo a cheap bolt on supercharger...

I'd seriously do some port and polishing first though.

wont ya loose ya A/C then?...

said it before and i'll say it again.....stickers!!! and possibly a gt-wing, and why do i keep hearing such bad things about rpw? are their products not all theyre hyped up to be, if they are all hyped up at all..... its just every time some one mentions rpw, its met with bad stories and stuff like that, so should i keep away from rpw products or what?

Some people have been burnt by RPW. Some people know people who have been burnt by RPW and hate them by association. Some people have had no problems with RPW. Some people have had good experiences with RPW. Some people have had a combination of all of these scenarios.

Choose your own path.

We have also done a Stage 2 with Camshaft, Cam gears, Valve springs, throttle body and extrators on a 3.5L TJ. Just over 170kW at the wheels. Apparantly breaks traction in 3rd and churps in 4th. A little crazy I think, but the guy loves it. Everything went straight on without problem and the Stage 2 wasn't too lumpy or too bad at idle, in fact quite streetable.

But for now, like AussieMagna said, just free up the breathing with exhaust, filter, throttle body and see how you go.

As for RPW..... Well, we certainly have first hand experience since we are their distributor. I ain't going to lie and those who knows me, knows I have a big reputation for straight shooting. I think their products are very good. Got a lot of research behind it and from the feedback we have, everything works as they are designed to. :cool:

The only thing about RPW is stock availability. They do tend to run out quickly and it may take some time to get in. So I guess people get frustrated and since they are in Perth, it's not often quick and reliable with freight delivery time. But they are using TNT now, which is way better than before. So if people are frustrated with waiting, it doesn't matter what arrives, they will bag it anyway. :cry:
