just got one installed quite good quality only drama was it needed to be heat expanded as it was hitting the floor pan or whateva but i can feel the extra power, also the bov flutters too much, im getting a bit scared its gonna destroy the turbo or something one day... hehehe (*thinks hi-flow*) anyone else had to do this? or has no one tried the jjr front/dump pipe

Heat expanded? Sounds like the fitter didn't know what they were doing.

There have been several members now that have fitted these on R33's and R32's with no complications

This has been covered in 3 threads already - When removing the factory front pipe to fit any aftermarket unit you need to check the alignment of the rest of the exhaust system when its all back together and adjust as needed as its common that you shift the rear section of the exhaust during fitting so the hangers and mounts move which can cause the system to knock around a little

fitted to my car perfectly. 33 25t s2. didnt need any bending on my own, pretty much just fit first go

only hard parts, getting hte dammed heat shields of and re-bolting the t3 flange was a much smaller mission

it didnt clear the floor pan properly, it was rubbing and hitting it...hence it needed to be fixed through heating....but the fitters were advan so i doubt they didnt know what they were doing...lol...i probably had a deformed one LOL 1/10000000 lol either that or because i didnt take just japs advice and get a high flow cat at the same time lol

I got the whole turbo back system from JJ and it came with X Force hi flow cat, so in theory it should be an easy job right?

      Let's hope that's not a copy pump either. There were so many copies of them back in the day.

      Damn it, I was at work last night, and stayed in a room there during the storm with the car outside, but undercover, I just went downstairs and well....there was a large steel locker that has come from some place last night, it wasn't anywhere I could see yesterday, and yeap, it landed on the fraking car....of course it did..... LOL So, I'll need to take it back for paint and panel, luckily it was only the boot that took the hit, so it could have been worse Serves me right for staying at work and getting on the cans with some of the boys

      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.
