Hi all,

My apologies if this has already been posted, but i failed to find it in a search.

I've just had a split dump pipe (Flying Performance) installed today by my dad (thanks dad!) and myself.

One thing that seems mildly concerning is it seems as though after a 45 minute drive, the engine bay is hotter than usual- particularly the area close to the turbo.

I've got a Series 2 R33 GTS-T. The only other mods are the $22 boost controller (dialed in at approx 9 PSI), Catco 3" hi-flow cat (came with car), 3" catback exhaust.

It doesn't appear that any coolant levels have dropped, and performance is fantastic (much smoother power delivery and rev's)- i'm just concerned about the temperature.

The stock temperature guage didn't go any higher than just about the middle.

Any help would be appreciated!

Thanks!

its probs a thinner material and/or not as good at holding the heat in compared to the standard steel ones, therefore will let out more heat...

Thanks guys- will do!

I probably won't get a chance till next weekend, so just in the meantime- is running it as it is now detrimental or unsafe? Either for the car, performance or the engine?

Quite fine to run it like that mate, i was running a s/s manifold and dump off my s15 a while ago for over a year.

Heat wrap is the best idea but you already put the pipe on so would be a bit of a bugger to remove it again but ohhhh well, you gotta do what you gotta do!

???? keeping more heat in with wrap may increase the chance of s/s cracking; especially with poor quality welding and grade.

Anyone have experience with this?

      Drivers R32 GTR seat

      By mtopxsecret6 · Posted

      Hi everyone, just looking to see what's available in the GTR seat options, testing the waters on what's available. Wanting a driver's seat to replace my old school OG jap race seat, going to re-register the car so need a factory seat. Prices currently seem to go from $300 to $2k for a driver's seat. What's options are there, that's good condition and actually a realistic price? Located Brisbane. Thanks

      Are these a plug and play setup, and do they need a tune, like a haltech ecu etc? Thanks

      Rob's S Chassis track cars. Now with more s15 and less 180sx

      By robbo_rb180 · Posted

      Been over 2 months since I have done anything on the S15 and had a day off today so got stuck into mounting the radiator and intercooler. I ended up using factory bottom mounts as bolted in and I did order some gktech top brackets but didn't work with the PWR radiator so made up some with aluminium flat bar. Spent way to long on them but pretty happy how they are. Next job was the intercooler. Used some more aluminium flat bar and did the bottom mounts first. Top was easy as just one long piece and 2 90 degree coming off rad support and welded them on. The bumper support required some notching to let the outlets sit where I want so will add some reinforcement later to strengthen it. I have also bought ecu and waiting for it to arrive. Went with a Link g4x Xtreme but will be adding a ptmotorsport expander to add a few extra inputs over CAN. Went through a few different configurations on pclink to get what I want to allow future expansion for sensors and gearbox upgrades. Ordered gktech rear arms but looking at the hardrace lower control arms to have some extra adjustment too will see how the alignment looks after first setup. Got 2 more weeks of work before shut down and will have almost 4 weeks to work on this so planning on hopefully firing up mid January.   Also bought a 2015 brz with a heap of good gear, did noosa hill climb a month back. Owned it for 3 days changed alignment and sent it. Finished the weekend 2nd in class and only .3 off the 180sx best time last year. MCA Red coilovers, gktech rear lca, bolt on lock kit and tie rods, whiteline toe arms, cusco 1.5way diff and 4.5 ratio, endless brake pads, headers, exhaust, perrin intake and e85 tune. Electronic steering adjustment, nankang crs with koya wheels 17x9 +35. Have bought rear traction arm and relocation kit, extended studs and v3 tie rod kit. Planning on also getting flex tune as lucky to get 300km a tank with e85 and short ratio. Car is a heap of fun to drive and super easy to work on. AC in the line up at Noosa was mint in 35degree weather.
