Gts4 - Turbo Conversion

[JDMLAW]

Hi guys,

I've got a '95 R33 GTS-4 currently at the workshop having new motor from Series 1 Stagea put in, however the stagea motor was from an automatic...

Talking to the mechanics there are a few plugs missing from the stagea loom compared to my GTS4 one for ABS, Wipers etc...

Does anyone know if I'd be able to run a engine loom from a manual R33 Series 2 GTST??

Cheers

Dan

Just use all the original EFI. I mean everthing. Then just chuck a tuneable ecu into it.

use the current loom, no need to put the stagea one on

Yes S1 stagea has what you would call series 2 RB25DET so coils at least will be different. You will need to upgrade the ecu as you suggested - I don't think you will need to change the loom but if you get the loom, with it you may as well.

But don't use the Stagea loom and ecu - it is an oddball 3 row ecu and you will have problems if you want an aftermarket one later.

u dont need to change the ecu at all.. and theres no reason why the current ecu wont run the s2 RB25

Thats right, just change the ECU and run your N/A loom and sensors (coil packs/ignitor/AFM).

oh its non turbo is it? didnt see that. well yeah need a turbo ECu

Thanks for all the info guys, I'm be putting in aftermarket computer to run it;

What are peoples recommendations I won't be going for big numbers, so would you recommend just a Nistune or Power FC...I've read a few threads saying not to get Greddy Emanage.

I'm just looking for budget at the moment as I just got back from an expensive holiday can always upgrade later.

Tuner's choice man, there are are few threads on these forums with Nistune vs. PFC, I'd probably go PFC for R33 since they're quite cheap these days; most tuners are happy with them and they are the easiest to install without losing vct or modifying loom for Z32.

I have a Nistune on my R34, they will both make the same power at the end of the day.
