yeah it does, ive got it flanged so i can put a replacement pipe in. That makes a real difference, once the car hits 3grand it just moves, with the cat on it kicks in from about 4500rpm, im gettin a custom track exhaust, from extractors will split in to 2 11/2 inch pipes and exit at the side :D will make a hell of a difference i reckon

yes an NA car does need a certain amount of backpressure but this is already happening through ur headers and the rest of the exaust system, gutting the cat deristricts the exaust a fair bit and is definately a noticable power increase, those extractors where 285 bucks plaus 150 for fitting, the most worth while mod i have done yet.

by keeping the exhaust at 2 1/2 it keeps the back pressure at a good level, gutting the cat is illegal of course and it does screw things up abit u have to gut it and put a stealth pipe in it, visible as a cat, but its a pipe inside a box. my old zorst was 2 1/2 all through

i've got an auto r33 - but its the 5 speed auto version with a really short 1st which helps acceleration - i get around 7.5-7.8s for 0-100 - i've god k&n pod filter with divider in the engine bay, that's it (running 98 RON petrol all the time and service every 5,000 with anti-friction oil - i reckon it helps!)

i beat a wrx with a bov one night - that was pretty funny i think the guy was a sh!t driver tho, and i can keep up with my mate's ca18 silvia (rebuilt and boosted to 12psi)

8.2 sec is a bit slo for a '33 - even an auto - do u torque brake?

i think its slow too!

i wana go against an r33 with the same mods or less and see how i go..

do i torque brake?

i duno wat that means

but if u mean start of with ure foot on ya damn brake and on the gas and take it of brake

then yea thats wat i did to get that time.

try doing a 0-100 with the stock wheels, since i put my 17's on it has lost a little accelaration (diameter is slightyly bigger) i got 225/50/r17 on mine, if urs are 45 or lower then it really shouldnt make a difference, but tyres and width can also make a difference. u lose out on speed but handling gains heaps:)

    • If you mean the alarm immobiliser; theyre internal to the alarm itself which makes that difficult; I couldnt even see where he put it; its not in the same place as last time; but with all black wiring it might be very challenging to trace  I had someone turn the key for me as I know it only primes for a couple of seconds As my post above; I am getting no voltage to the pump at all; but I am testing continuity of the power line (SB) from the pump plug to the relay fine. As well as the negative from the pump plug to a 12V constant.    Yeah; he blammed the no start on a bad battery; said I needed to get a new battery and it'll start. Turns out the battery drained because the tail lights had been on for half the day during the install (the rubber cushion on the brake switch gave out while he was testing it as I have a picture of the car from that morning with the tail lights off..i've replaced that). The battery was turning over the engine just fine for a long time; but got low since lights were draining it so it was too low to test a start after he finished. I bought a new one on his advice...$250 wasted. My original battery charged up just fine and is healthy.    It was running perfectly fine when I messed up the old alarm (programmed out the remotes). He couldnt start it after removing the old alarm; my assumption is that when he unhooked it; he didnt bridge the circuit back when trying to start it. Its always been perfectly fine. The ECU swap and pump were 2 years ago. It's never missed a beat in that time. 
    • This is a big issue for me without the diff. I just have zero drive from the passenger side when drivers side has no traction. Bec's parents place has a crazy steep driveway with odd camber and I have never been able to get up. My bro-in-law's 130i with an (unknown brand) LSD gets up fine as does their dad's Hiace. My car stays at the bottom. We have other odd camber roads around here as we're elevated a bit and if it's raining I can get totally stuck around some hairpins. 
    • Yeah, I am super excited for this.
    • Was the car running before he touched the car?
