Difference Between R33 Gtst S1 And S2 Tps?

[brother_david]

Searched and not really found what the difference between these two is, so dows anyone know what it is?

Im using a S2 engine with a S1 loom/harness.

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.

If youre running manual i believe its just a matter of wiring it to suit

1- 12v ign

2- ground

3- 0-5v output to ecu

Or just get a complete S1 throttle body and use that

Wiring aside, the way they physically connect to the exhaust camshaft can be different. Make sure you have the right pattern as well.

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.
