Hey guys i have an RB25DE laying around ready for installing on car but i can't seem to figure out which series it's from and it makes it very difficult to buy parts such as AFM and service parts etc. So if you guys can just have a quick look and drop a comment that would be nice :)

Wrecker who i bought it off says it's series 1 (from my experience they're not very knowledgable), but from this forum i read that series 2 doesn't have the ignitor on the top of the engine as it is built into the ECU. Attatched is some pictures of my RB25DE and i have tried searching everywhere.

Thanks.

Looks like you have a Series 1 but the ignitor is missing. Its usually mounted at the rear of the coil pack cover.

:D

Hmmm how are you sure? I've seen some R33 engines where there was a stand just like the one on mine at the end of the coil packs cover but however it was 2 plugs joined together (the stand was to hold the joined plugs up) instead of 2 plugs on each side of the ignitor... :)

After a closer look I think you are right actually. The stand you are talking about is there (I didnt notice this before), in place of where the ignitor would normally be mounted and the plugs look different too.

Heres a pic of my old Series 1 outlining the ignitor and plugs:

To be 100% sure, Id check the coil packs. If you post a pic of one up here I'll let you know for sure. :D

I would say it is a series 2 engine. The plug is the same as my series 2 as it dosent need the igniter. The series 2 is about 4 pins across and 2 down. And the picture of the series 1 ^^^ that has the igniter has a different plug (looks like 1 row of 8 pins) that looms off to coils. hope that helps

I also think it’s a S2 motor however I am unsure if the non turbo RB25 follows the same conventions as the turbo version. The TPS is the 2 plug type which S2’s have. Also, the S2 motor has a pink label on the AFM, not a green one which would be for the S1.

I through that S2 RB's had the eno head's on them

soo wouldn't it say it somewhere on it........

Thought that was for R34s? NEO technology was only introduced at 1998 onwards. Please correct me if i'm wrong someone.

+1 for being s2. the tps is the first thing i looked at

definately a s2 , it has no ingnitor for the coils , which means you'll have to change your ecu , it's built in to the ecu

the ignitor on the s2 motors IS NOT built into the ecu. it is built into the coils. some people on this forum may say that the ignitor is in the ecu, those people are also wrong. this is the reason why s1 and s2 r33's have different coil packs. i have personally run a s1 ecu with an s2 motor, so i can 100% garantee that it can be done.

      Yeah pretty impressive hey, good to see quality products not over-shooting their prices. That's what drew me to buy the hypergear turbo, just a shame I've never got the chance to see it in action

      Thank you GTSBoy and MBS206 I have done the compression test with the motor out of the vehicle, reason for the test was to see if I needed to remove the head and do rings etc while its out. I'm in the process of respraying the vehicle and tidying up a few things. Story behind it all is I've just purchased the skyline and it was running when I got it, never drove it on the street though as I wanted to pull it down and do it all up again before registering it. the gentleman I purchased it from told me the motor has a forged bottom end and has a decent tune through it but I was going to pull the sump off anyway to see if it is a forged bottom end. that's why I thought id do a compression test beforehand.

      Man, I'm kind of amazed that the price of the turbo has not changed in 7 years. Everything else is inflating beyond reason, but not this? Good on Tao / hypergear I guess? Anyways, good luck with the sale!

      Hypergear ATR45 SAT Turbo With addons (brand new - never used)

      I'm selling my brand new, in the box, never used Hypergear ATR45 - and I had some additions I paid for a few yrs back when I purchased it. Never ended up having the rest of the money to add all the mods at once, so I just ended up slowly selling each part. I originally had it internally gated, with the dump pipe, however I found it was incompatible with what I was going to use it for, so I contacted (I think Ken) from Hypergear, and he and I messaged back and forth & he got me to ship the turbo back, where they modified it & made it externally gated, and gave me the 5 bolt dump pipe attachment for custom welding. (Photos below) This turbo like I said has never touched the inside of an engine bay, it's completely brand new, never used, been sitting in the same box it arrived in, covered in plastic & all. Below are the photos of it: And while the guys at Hypergear were making it in-shop, they sent me some photos of the process: I'm looking at selling this just because I'm in need of the money right now, and don't have plans on modifying the 34 anytime soon - and from reviews & peformance sheets, this turbo had amazing results back when I was researching. The turbo was purchased in 2018 for $1.9k, with the mods I got added on. Looking at the website now, for the same turbo they sell (ATR45SAT), with the current addons it adds up to $1830 for the turbo Current addons included: - Bolted dump adaptor - Ball bearing CHRA - Braided oil feeding line So I'm looking to possibly sell it for around $1800, with shipping included in that 1.8k, It cost me around $120 to ship - so yeah thought I'd throw it out there and see if anyone was interested in purchasing. Cheers!
