they physically appear different

the series 1 has an extra block with 2 extra wires, i dont know what it is used for or what it does, but it is physically different

if you go into the howto area and look at series 1 vs series 2 from memory there are more details and pics in there

Thanks mate! Had a look and its clearly a difference with one/two connectors. Form building my RB30 using a Q45 TB i remeber that it has two connectors too but i just used one, no problem.

I guess now my question is if its possible to use the S2 TPS with my S1 loom? Been reading alot and one of the posts stated that there is no problem at all, others stating that there should be.

Just realized I responded to this thread thinking you had asked about CAS and not TPS. Sorry about that. I recently replaced both and also had to rewire my TPS (using Q45).

Series 1s have an igniter pack on top of the valve cover ,it has 2 green relays that sit in the engine's harness, one for the ecu, the other for the ignitor/coils, and it shares the same coil packs as the rb20 and 26's.

Series 2 has individual ignitors built into each coil pack ( vs) one for all (series 1) which is also why it only has 1 green relay in the wiring harness which is for the ecu. and other electrical differences.

Also the MAF sensor and plug...... 3 prongs inside the MAF connection = Series 2, 5 prongs = Series 1.

TPS aka ( throttle position sensor) sensors are diffrent on S1 vs S2

and i belive that the cam angle sensor are diffret between the both.

other than that i belive thats all the diffrences between each other...... they are the exact same thing and produce the same power, same turbo ect.... other then theese diffrences listed above, its the same S@!T hahha

Not the same turbo though.. ;P The S2 is a ceramic one, the S1 is a metal piece meaning itll last longer :)

Ill have to investigate all this with the wiring to the TPS, guess ill hook up NisTune and check if it gives a correct signal, better use a low-amp fuse when testing it out so that i dont sent 12v instead of 5v to the ECU.

Not sure about the CAS wiring though, they are different but a friend of mine has got a S1.5 (non-igniter, should be S2 engine) but he has got a S1 CAS by the looks of it.

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
