Turning Cat Back, To Turbo Back

Hi all,

i currently have a Blitz Nur Spec 3" Cat back system on my car (Cat is standard), and im am thinking of going from the turbo back but i need a bit of guidence.

First of all, i read about split dump pipes and one piece front pipes, but that has just made things more confusing and difficult to make a decision. my main aim is to basically decrease lag.

What do you all recommend?

The car is pretty loud as it is with the cat back system, will it get louder if its a full system?

Im also after a hi flow cat, i hear catco is the best, do you agree?

Should i keep it all the same brand, if not which should i go for?

Anyway, please post your opinions.

Thanks.

OK I'm going to jump in before everyone else crucifies you for not doing a search first....

Just go out and buy a BATMBL split dump and front pipe in one (dont get stainless its a waste).

And whilst you are there buy one of his metal cats.

You wont be disappointed. THis is the route I'll be going when I have the cash.

Do a search for the thread, its in the business traders section, with dyno results etc...

As said above: Go with Michael's (BATMBL) split dump and front combined pipe in the Business Traders section. They are well designed and pre heat coated in mild steel. Definately choose the split/seperated dump if you want to reduce lag.

Regarding the cats, if you have the money definately go for the Metal Cats or the 5" body metal insert Catco cats. Otherwise get a 3" hiflow cat from Xforce for around $160 delivered - this is what I'm doing as I'm only aiming for around 200rwkw.

Noise mainly depends on your cat-back system. If you would like a quiet exhaust I'd advise adding a mid-muffler (box type) between the cat and rear muffler. Most quiet exhaust bolt on systems (Trust PEII, Fujitsubo Legalis R etc.) have a rear muffler and mid-muffler.

When I had my cat-back only on the GTIR the only increase in noise I noticed after adding a dump/front is that it was slightly more lower pitched, not quite more loud in volume. If you knwo what I mean.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
