3 Things...

As the topic says what size is the std exhaust on a R33 GTS-T?

Also if i upgrade IC & add boost (10psi) i know it is beneficial but is it NECCESSARY to increase exhaust size???

Lastly what do you guys think of just getting a 3" from turbo back with a split dump pipe & high flow cat but leaving cat back exhaust as std?

I dont want people blasting me saying im stupid etc especially since i have not done any of the above but i would like to hear your informative opinions & reasons why & why not.

Thanks

Hi Noel, Sort out your battery issue?

yea thanks I got myself a 450CCA battery (MF55B24R) from Supercharge Batteries http://www.supercharge.com.au/ in Arndell Park & problem is now solved ;-)

yea but is it neccessary to do it (exhaust) if i up the boost to 10psi & get get a better IC? or is it just better to do it?

if its gonna cause damage to my car cause i have a std exhaust i wont boost it all all but if its gonna be fine and just wont go as well as it could, i'll do it & leave exhaust (for now) especially since i love it being quiet as a mouse atm with the std exhaust.

Thanks

there is no point upping the boost on a stock exhaust. it won't be able to flow enough air to make it worthwhile. you need to be able to let the air out properly before you start pumping more in. also it will hold more heat in.

makes sense...

what about just getting 3" turbo back/split-dump & cat vs just getting 3" cat back exhaust?

I know both is the ideal but if i were to get one or the other which would be more beneficial?

Thanks guys..i am just interested on peoples opinions/feedback on these ideas?

Cheers

Noel

a full turbo back is going to give a better power increase, as well as get cool the turbo slightly (the hot gases can flow away from the turbo faster). generally if you get it in 1 hit (like a full x-force turbo back system) it works out a bit cheaper than buying a cat back, cat and front pipe seperately. just depends on what you want. if you were going to just get a cat back i'd get the cat at the same time.

Yeah id deffinately get the hole system it will help make the whole set up much more efficient. I also found my boost went up a couple psi by having the split dump and turbo back exhaust due to the much better flow.

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
