Ok fitting my front turbo dump pipe and xforce cat this weekend to my R33 GTS25T is there anything i need to know or do just to make life easier in the process i only have access to ramps and trolley jack.

I already have a Nismo cat back 3 inch system so im guessing a cat and front splite pipe from turbo should fit on np.

Use plenty of lube! Those bolts and nuts are going to be rusted. Might want to buy a whole new set of high tensile fasteners. If you're removing the dump pipe, you might as well change the turbo outlet gasket, if you haven't done it in a while.

Are you using the stock front pipe? This piece has a little lip where it meets the dump pipe, meaning the internal diameter tube sticks out from the flange, and it might not fit properly into your new dump pipe.

Make sure you are using the proper Steel gasket for the dump pipe, if you get given one that looks like paper between two sheets of aluminum then give it back cause it will leak, tighten the bolts a little at a time and evenly, and dont cross thread anything or you will want to cry and swear alot :domokun:

Ok yer i was guessing rust would be prominent as far as i know the its the whole system from turbo and cat so im not using any stock exhaust components except bolts.

i was also told use Loktite on ALL exhaust bolts dont drown it just a swipe on 1 side of the bolts or nail polish if i dont have loktite.

Is there any gains in cleaning my o2 sensor if so how would i go about doing it if i can.

also i remember on my TX3 i had a turbo to manifold gasket that was like a perferated steel looking thing it burnt out same day it was installed and started leaking so i stay away from that crap.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
