rb25det neo(from stagea) with r34 gtt ecu

hey guys i wonder if someone can help me out, i have few wiring problems a can solve myself.

- original car skyline r34 sedan rb20de neo

- swap rb25det neo ( aparrently neo from a stagea since it had 4wd oil sum, and does not have the traction control on the engine) I KEEP THE ORIGINAL LOOM FROM RB20DE NEO.

- first engine is working with r34 gtt ecu.

- engine works fine without the TCM/ABS module ( on r34) disconected but no speedometer

- engine cuts at 4000k when disconeccting the TCM/ABS module.

- i got and stagea ecu to solve the problem (stagea NO ABS or TC), engine pass 4000k normal, i connected the module TCM/ABS and now speedo works and all good, no cuts or etc,

problem i remove the ingnition key and the engine doesnt shut off whith stagea ecu, how can i solve this? please help

PS - my stagea ecu is 23710 0V300 and the first one is from a r34 gtt.

just for the record, my engine also cuts badly at 1 k or 2 k when i plug the ac dryer (3 cables) with either ecu.

Its not the right ECU. The number you quote is for a S1 Stagea with the R33 engine. The Neo engine runs a Jecs ECU. The plug is different. You need to use the 34GTT ecu. BTW all Stageas have ABS. There is a fix on this site for if you have a warning light for the lack of Traction Control.

What happened to the RB20 in the car? Interested in selling?

Hey guys, so is it possible to put an rb25det neo out of a series 2 stagea into a r34 gt (non turbo)?

a) ill be using an r34gtt manual gearbox and a r34gtt ecu

b) Do the engine mounts line up the same?

c) can i use my r34 gt hicas power steering pump on a non hicas stagea engine?

d) can someone link the fix for the traction control fix?

Yes

a) ill be using an r34gtt manual gearbox and a r34gtt ecu

ok

b) Do the engine mounts line up the same?

dunno - probably big question is is it an awd or 2wd stagea

c) can i use my r34 gt hicas power steering pump on a non hicas stagea engine?

if it doesn't bolt straight up you should be able to adapt it

d) can someone link the fix for the traction control fix?
