Yeh i was thinking it wouldn't make a big difference. I'm gonna stick with a split dump. Just wanna pick a good all rounder.

Thanks mate, i'm interested. If it's a great bit of kit then its a steal. I need convincing cheaper=better :)

Yeah its a pretty good price, so ill have a good inspection of it before it goes on.

I always thought that x-force stuff wasnt the greatest, iv seen a set of their headers, and shit. The S/S is paper thin!! Build quality looks great tho, and in this case, the x-force is more expensive. We will see.

Got mine from bos importing.

I ordered one from there and they delivered an AM Performance one so you might wanna call them and see if they can do one for you. I'd recommend this pipe, had a mild tanabe cat-back on before the front/dump and hi-flow cat went in. Is very quiet at idle and when you give it some stick, opens up and has that wicked raw RB sound :P

Hey,

Got my Split Dump/Front from JustJap earlier this week and went about attacking it at home.

The build is really good, the photos on the page dont do it any justice (hint.. change them :) )

So anyway.. my thoughts.

The two problems i encountered, although minor, now i figured out what i need to do means unbolting it again.

1st problem, is one of the bottom nuts on the flange wouldnt fit. The pipe is fat, and bends qucikly out of the flange stealing the room needed to put the

nut back on. Silly me bolted it up anyway thinking id get a mte to fix it ;)

Lying in bed.. DOH, if i had the nut in place on the flange while sliding it on, it would have worked. So simple fix, but being bolted up it means i have to do

it again :) I didnt get any exhaust leaks, so ill wait till i get on a hoist. Its a pain using the scissor jack and stands haha.

Problem 2, is the wastegate pipe touches the turbo water feed.

It not ony touches it but you actually have to push it up to get the dump pipe to fit. In turn, pushing it up also pushes it against the manifold shield.

A quick solution is bending it out the way, i did try this, but f**k me that line is strong! And i dont want to break it off the turbo personally.

Again i will get my mate to have a play as he is RB king. Might even replace it with a braided line so i can put it where i see fit.

It will be ok temporarily, but constant rubbing and vibration it will eventually wear through.

Sorry about the asshat image. My camera is odd sometimes.

As i suspected i didnt feel a great deal of difference. It sounds a bit cleaner than it used to on boost. And for the price, its great :D

Hey Simon, is there any clearance issues with these AM jobbies? After seeing slight problems with just jap ones bit hesitant. im from Ad's so i dont mind checkin this out. Ne help is appreciated mate

I'm using the batmbl (bosimporting) split dump + front and its a good piece of gear.

If you compare the wastegate piping with the JJR one and the batmbl one you can see that the JJR one has a pretty tight 90degree bend in it whereas the batmbl one has a gentler bend.

Probably wouldn't make TOO much of a difference at said power levels but either way, straighter piping would flow better.

Not criticising anyones pipes , I like the idea of a dump pipe that bolts to the engine pipe because with the 3 bolts/nuts removed you could very likely lift the turbo and dump pipe out as an assembly .

These Hitachi turbos are pretty tight around the dump fasteners and it would make life easy to fit and remove them on the bench . Once the turbo/dump is on the engine fitting the engine pipe up should be same as std .

Just my thoughts , cheers A .

    • Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels
    • Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)  
    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.            
    • Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.
    • Wow the colour matched hard top completely transforms the car. Are there any nice front lip options for the car or is that off the table?
