My brother's mate's cousin said he saw a stagea like ours with a full exhaust and it had less power. I'd rather take his story than believe people who own the cars and have actually done the work :D

Hah! That's GOLD. Why is it that everyone believes the crap they "hear at the pub" over, well, the TRUTH!

For me I am getting it purely to lengthen the life of my turbo.. Don't care bout economy/power increase.. I'm much more worried boutthe cost when the turbo blows.. Which will come just hopefully not too soon!!! I say for $400 odd dollars it's a good investment over that under-engineered piece of crap Nissan call a dump pipe!!

for me it was such a discernable difference that when i drove away from the exhaust shop.. i could feel it on the first hill exiting the driveway.. gets on boost alot earlier and the torque was heaps better off boost also. what amazed me was the fuel difference.. someone said its not going to get 6l per 100.. well its pretty damn close.. its going to get 8-9 with the dump and cooler mod ive found...(against 12+ without) again depending on how you drive at the time. but i noticed a huge improvement on fuel economy. (almost a quarter of a tank difference over a week just crusing up the hwy).

is the economy due to the fact your turbo is laggier and youre not on boost as much as you would have been therefore not using as much fuel?

i found that with my SR20s with larger turbos. The car drove quite well off boost due to being in traffic/cruising mostly. on boost was another matter :P

Andy and Dale are right on the money

Couldn't agree more.

I think I will....... go........ with those who........ know.And that's why I joined this forum

How many hours ( approx)to do this by an exhaust shop ( I presume would be the best option) as I cant do this.

lol!!!!!!!!

As a person who has probably done everything other than an E85 conversion to get the most out of turbo that choses not to work with the car but should work with the car and probably would with any other car!!!!.....but this car is "NOT THE SAME AS MOST CARS" so it doesn't....yet!

Order of noticeable improvements

1. THE F$#KING DUMP!!!!!!!

2. A good air filter

3. The Exhaust

4. FMIC

5. Turbo

6. ECU upgrade or piggyback + Injectors +runner spacer + Fuel pump + suction pipe(good luck with this one as there are only a couple of people that can do the ECU properly)

Order of improvements for the summer weather

1. THE F$#KING DUMP!!!!!!!

2. FMIC

3. Phenolic runner spacer

4. Nismo thermostat

Sorry if I have offended people but.........oh f#$k it! If you don't believe us do your own thing!.....maybe shoot Gale Banks an email and ask him about the VQ25DET!

Well said Craig, f##ks me why people want to keep re-inventing the wheel...

Why believe anyone who's done EXACTLY what you're gonna do? What would they know anyway?

Will start collecting when they are almost complete. probably when we send them off to get ceramic coated.

I'm just waiting on my mate to get some time so we can get started. i'll go sort out the flanges to get laser cut soon.

They will charge you through the arse for it, but they shouldn't.

It is tricky, but if a couple of non-professionals can take the dump off in about 2-2.5hrs without a hoist, I am sure a pro could get it done in under 2hrs.

(and no, it is definitely NOT an engine out deal - I think I forgot to answer that q in your pm, sorry)

Dale, you definitely do NOT want to do exactly what Craig has done, mate.

yup i can confirm the dump install is a bitch of a job. but with the right tools and getting the car high enough youll be fine.

just gotta drop the rear of the transmission down to get access to the top bolt of the dump. long extension, uni joint and plenty of torque will do it no problems at all!

You make it sound so easy when you put it like that :)

Not sure if I put my hand up in this thread yet or not, but I need to get rid of my pesky dump-cat too :) I'll probs attempt to install it with a mate using a hoist, key word perhaps being 'attempt' :)

      thanks for heads up on actuators - will sort something as back up or solution as yes dont need that have enough trouble but no doubt some addition of something to spares boxes is required yes have a clue about WTAC but nothing has been officially put out yet so will wait to see exact details Pro class is, has been and will become a draw card for lap records and one off builds for show and thats about it I think - be interesting to see how open they make it Pro am is the old Pro in reality Open class will be split into 2 with slicks and 050's with no doubt slight variances in allowable drivers and changes in aero Clubsprint + apparently a true street class   They have to and are refreshing it all and bringing things up to current standards and need to 100% adhere to rules because whether people like it or not / or say it or not - for alot of competitors it is sheep stations and has been for a while when Im getting told I was illegal because i cut my rear bumper too high and yet others where in the grey areas of legality with everything from engines, suspension, ride heights and more serious influences it actually got quite out of control and heated this year so as much as I may be impacted by some of the changes and prob spit the dummy when I have to spend money changing things I think its a good thing for all

      I can’t tell if it’s suspension related or maybe wheel bearing or motor mount.  IMG_6209.MOV

      Start with a multimeter, and see if you're getting power at the TPS. There should be a manual for your car somewhere on these forums and it'll have the info for what closed TPS signal voltage is, and how it should sweep to full throttle. Same as for other sensors / valves.   Have you checked things like your base timing etc? See if anything looks amiss there too?

      here are 2x options to consider: https://www.selby.com.au/price-promise/tonewinner-sw-d6000-subwoofer.html https://www.apollohifi.com.au/svs-pb-3000-ported-subwoofer-black-ash-pre-order.html I'm waiting for a good BF/CM sale and will pull the trigger on a new sub, I do like the SVS PB-3000 (13") but you could nearly buy 2x Tonewinner D6000s (15")
