I am from the States and I find that you guys are more knowledgeable in this area than I am. I have a 1994 Gts25t and I just bought a down pipe made by XS. Has anyone ever heard of this downpipe with dual chamber? I plan on running the car without a CAT. I have an HKS cat back exaust on there as of right now. I bought the car and had it brought in through Motor-ex and I still do not know exactly what exaust I have on the car as it came from JAPAN that way. Can I adapt that XS duelly pipe to the HKS (?) exaust I have on there if I just weld a custom straight pipe? Also would I need to get a new turbo exaust manifold for this duelly XS dump pipe to work? PLEASE HELP The gaskets and bolts come with the XS. :rofl: fallout

Most after market dump pipes, be they spilt (dual) or not, are designed to bolt straight up, is this XS pipe just the dump part (about 6" long) or the dump/front (4 foot), if it is the dump and the front pipe is standard you would be better replacing it to the catback with a 3" pipe, if it is dump/front just get a pipe made to replace the cat.

Here is what I ordered:

ECR33 Trust MX Front Pipe

TSS stainless steel 02 housing for RB20 (same as RB25)

Here is what I have existing:

HKS cat back system

Here is what I want to do:

Eleminate the Cat totally

Here is my plan:

Bolt on TSS stainless steel 02 housing 1st

Than bolt on Trust MX Front pipe coming from housing (elbow)

Cut off catalytic converter

Weld straight pipe on other end to my HKS

WALAAA! Now I have a really loud car with good hp gains (KW)

Does this plan work out right?

Thanks for your help.

Works out great, if you wanted to retain the original setup, you could get a pipe made up with the same dimensions as the cat that would bolt in, that way you could go back to a cat, for resale or street use.

      By jtha7 · Posted

      Hi guys my 94 r33 gtst fuel pump has gone out. I have a walbro 525 ready to go in but am unsure if I need to upgrade the fuel tank bulk heads? Ive heard that others have issues with the stock wiring melting... Ive seen alot of people recommend this: https://frenchysperformancegarage.com/products/fpg-nissan-skyline-r33-r34-silvia-s14-s15-billet-fuel-tank-bulkhead-hat-top-an6-with-high-current-connector-apex-2-8-delphi-fpg-100?variant=42873255198898 My current pump that stopped working is aftermarket but I had no relay mod or upgraded connectors. Need some advice please. TIA

      It’s new. It’s the cd009. I did take the transmission apart to mill down the bellhousing and had both housings come off the gears so wondering is something isn’t in right. I am running redline. I can get it in gear running too but it’s just not easier and it’s almost like 2, 4, 6, and reverse all the back gears aren’t happy going in

      Got keys and did a walk around the yard planning the landscaping works with the family that I will be doing Main effort: remove all the woodchip in the gardens that are around (attached) to the outside of the house and replace with 10mm blue metal, having woodchip close to the house is a recipe for inviting white ants, currently there are no white ants within the block and I would like to keep it that way I'll be buying some large raised garden beds to grow veggies and stuff, and the woodchip will be mulched with everything else that gets dug up, pulled out, or cut down during works Next will some minor drainage and landscaping maintenance up one side of the house, where the fuse box, AC, and solar stuff will go, about 12 mtrs long by 2 meters wide, I'll break up the soil, add gypsum and then I'll dig in a French drains about 300mm deep x 300mm wide and fill it with agg pipe and blue metal, then level out the whole area with a 50mm layer of blue metal, the soil, whilst currently pretty compacted, will break up well with the gypsum to aid in drainage, I'll then cover the area with a 50mm layer of more blue metal In saying this, the drainage issue is minor, but that little hidden away area down the side is untidy and weedy, and as all of the main elec stuff is there I want it neat and tidy to appease my OCD Again, the material excavated from the French drains with be added to the garden bed mulch, as will some rose bushes and some other crap looking garden plants, and a old apricot tree that is looking worse for wear The apricot tree is currently in a little roundish garden bed that is in the middle of the back yard with few other crappy looking plants around it, that will all be removed, levelled, re-turfed, and is a perfect spot for a hills hoist There is also a area about 3m x 2m between the rear fence and shed that will get some attention, it looks like some stuff was stored there and the grass is dead, that will also get broken up and mulched, and is a prime spot for a pumpkin patch I've guestimated that I'll need: 3 tonnes of blue metal, 12 meters of agg pipe, 5kg of Gypsum, and a hills hoist, so a few bags of concrete as well to set it in place (the house currently has one of those pull out 4 line jobs, whilst it works, I want a retro old school hills hoist), I am also going to run some chickens, there's a great spot for a coop, so a chicken coop to suit 4 of those lovely egg laying bitches will also be on the job card That should keep me busy for a while, and will finish off the back yard ready for a early spring planting of some veggies and berries  Once the main effort is done I'll start out the front, there's a large rock garden that could use some TLC, but that is only minor works Should be fully moved in within 2 weeks, the landscaping works will start then Fun times, retirement is good

      Steps to DIY sanding car back ready for respray....

      It happens, that's what your single stage filler is used for.  If it is still visible after the 3 coats of 2k primer, it will be visible after the paint is laid down.  Its hard to give 100% perfect advice without being there in person, I'm very tempted to say stop where you are, fill your pin holes with a single stage putty first then keep going.
