You can either get the short type eg HKS or the longer versions which Trust make. There are also 100's of knock off version available.

The HKS type replace the existing dump pipes in your car & will tie into whatever exhaust you have. The Trust type tie into the exhaust just before the cat - so you don't need a front pipe. For me if I would buy the Trust gear instead of the HKS dumps AND front pipes. However if you have an exhaust with an aftermarket front pipe (many exhausts use the stock ones) I would just buy the HKS dumps.

The Tomei ones fit the same as the HKS type, but do not segregate the wastegate flow aswell as the HKS units.

Just about everything will fit your turbos.

why you changing so soon?

Pretty much because I like spending money on nothing :(

There's absolutely nothing wrong with the HKS dump pipes... They're brilliantly designed and pieces of art. I just want the higher flow capabilities of the Tomei dump pipes.

On a similar note guys.. when replacing the dumps you are going to lose the stock heat shields. How important are these and what are you guys doing about it ?

If its necessary, im thinking of wrapping mine in that fabric that keeps the heat in. I know theres ceramic coating as well but sounds expensive? Or are yas putting the stock shields back on by welding ?

You should wrap them in exhaust wrap if you intend to track the car in my opinion.

That or have them ceramic coated.

Correct me if I'm wrong Richard aka BB. I think it was you that once said "you shouldn't wrap your dump pipes cause it can cause cracking and increase metal fatigue by keeping the heat in the dump pipe by wrapping it"?

Is this correct? if so what can be done to keep heat out of the engine bay?

Also does the price of the Tomei dumps justify the performance gain?

The people that have fitted the Tomei dumps notice a "significant change" before and after fitment?

In terms of less spool up time?

cheers

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
