Now that the box was in the garage, the work could begin. I was curious as hell, whether the engine was in good or bad condition…
So open up the crap!
What a great view 🙂
The RB25DET was all strapped and packed.
But it already looked tempting… so I was kind of tempted to work on it!
The engine is a 1996 RB25 Series 2 out of an R33 Skyline. I had the first belt an waterpump on it, so it must have around 80’000-100’000km on it.
The package came with the – well searched after – RB25 manual transmission. This tranny is very rigid and can handle great amounts of torque. Above, an interesting comparison between the CA18 (left) and RB25 transmission. The RB tranny is a monster compared to the one of the skinny 1.8l.
The wiring loom, ECU and all the sensors were strapped to the engine. Unfortunately, the loom was cut here and there. Also a few sensors were smashed, maybe due to incautious handling of the engine when packing. No big deal, ‚cause I decided quite early to go for a standalone ECU, to reach my performance goals.
So then I started dissasembling the engine step by step, checking every part for its condition.
The old turbo did look an feel quite ok. But it was not going to be up to the task since I was planning go beyond its performance (boost) limits of approx. 340hp. The greatest problem there is the weak ceramic turbine wheel, that does not like boost pressures above ~1bar.
The engine was, to my excitement, completely stock. This is a great base to start from!
A first glance a the sheer length and width of the whole big block (with transmission attached) didn’t make me very optimistic to be able to drop the engine into the S13’s bay without major issues.
In the next few months, the mockup engine will be put in and pulled out a lot of times. So this procedure needed to be as easy as possible. I then decided to cut the front support bar and make it removeable.
While waiting for parts I already started to work on the interior. Since the engine will be able to rev and also topspeed significantly higher than the CA18, I wanted the stock S13 dash to go… ok it was also because of the looks 🙂
more on that later…
Since the engine will take a lot of space in the engine bay, I wanted to remove as much as possible out of there. The battery and window washer tank received a new home in the trunk of the car (pic above shows mockup). A nice space-saving effect for the intercooler tubing that was planned to run that way.
In the meantime, a lot of goodies for the engine arrived! 😛
stay tuned for part 4!
