Hi guys had a few silvias and 180's in my time but only recently decided to start a build thread: I purchased my stock standard unregistered 1989 ca18de auto Qs series S13 for $1800 (probably too much), It had been sitting for around 2 years, was in average condition body wise but the underneath was straight and clean, was running rough and the guy i bought it of told me the auto stalled. I picked up the keys went and bought a new battery and it started first shot too the sellers surprise, i drove it home (10 minute drive) with absolutely no problems other than the auto holding gears for too long. Being a P Plater i didn't want to go turbo, My plans were to just chuck a manual box in and some coilers and put it on club rego. The car club i joined was an hours drive from my house, which is were all the problems arose. Because the car had been sitting for so long the petrol was obviously going to be foul, the fuel gage was just above empty so i thought id just top up instead of draining it, After I filled up with petrol and stopped at the next set of lights the revs were dropping and the car would shake as if it was about to stall, from there on overtime i had to stop or slow down the car would stall, so for the rest of the drive id brake with my left foot while accelerating with my right foot trying to keep the car going (was very stressful). Got to the car club they looked over it gave me the paperwork and of i went to Vicroads to pickup my plates. Left the car at my mums house not wanting to drive it because it was stuffed, looked around for a CA18 manual or even bell housing with no luck (I'm very impatient). I found a few sr20de and box combos but no one would separate them, so i was contemplating just doing an sr conversion, but my daily is an n/a s15 and i wanted something different to that. After looking all over the internet I came across a guy who had a smashed r33 gts rb25de manual that had taken a front left hit, it was in a towing yard and had been for 3 weeks, he wanted $1500 for it but ended up giving it to me for the price of the towing and storage fee roughly $800. I had the r33 towed to my mates shop Australian Speed And Custom where it sat up back and we gutted it to a bare shell within the week, I kept what I needed for the rb swap, sold whatever I could then I scraped the rest. Had pretty much brand new HSD coilovers which I traded to Elliot the shop owner who was doing the conversion for his labour. Next was removing the ca and auto, sold that straight away, then put the r33 cross member and steering rack in. Cross member was out by a few mm probably slightly bent from the accident so we slotted the mounting holes and made it fit. I traded the brake setup (4 stud) for a 52 mm r33 rad. Put the RB25DE in and realised the bonnet wouldn't shut, the new radiator also wouldn't fit as it was too high. Did some reading and found that and r32 cross member will sit the engine lower and further back, out came the hammer to massage the tunnel as the bell housing was now touching it, After "massaging: the tunnel the motor and box now fit and the bonnet would shut. Also had Elliot make up a custom gearbox mount. Found a guy on the drift sales page on Facebook who had a Type X and wanted to swap for an s13 front so I jumped all over that and chucked it straight on the guards had a few dents and the brackets holding the bar were missing but a few cable ties later and it all fit up nicely. Next was waiting for the auto elec to come wire it up so the motor had a full service, after the custom loom was done, it was time to test if it all worked.... it didn't, the engine was cranking but it would not start. There was spark, there was fuel in the rail and the injectors were pulsing, but it just wouldn't start. Changed the fuel pump to an r33 pump to see if that was the problem, still not working. Pulled the rail out replaced injectors, but they still weren't squirting. Had the auto elec come back in and check everything, 3 hours later realised the injectors weren't getting a full 12v power so he took power from elsewhere cranked the motor and it started! But the water pump was leaking so ordered a new one. next was getting the clutch to work, put the skyline pedal box in after some customising to make it all fit, only to find that the clutch pedal would foul out on the floor and not pull the master all the way making the pedal not spring back. Tracked down an s13 clutch setup and chucked it in and now its working correctly. Water pump that was purchased doesn't line up correctly so have had to order another one, which hopefully will come tomorrow. Front sway bar hits sump so have purchased a 3 way adjustable whiteline bar that apparently fits, will (update when installed) I purchased som JIC coilovers cheap but have decided not to use them as the rears are not base height adjustable and i want to be able to fiddle around adjusting them to suit the new feel of the car, I also would prefer brand new ones anyway. So when I get my new coilers ill put in the full hard race arm setup I've got and go for a wheel alignment. As this car is going to be a street car I don't want to make it stand out too much so will sit just below legal height and won't go to crazy with camber and toe, but being N/A ill need it to be stiff to get it sideways. I know the car isn't legal for a P plater let alone anyone, but my thoughts are its not turbo and as long as i don't get pulled over by someone who knows the difference between an rb and ca i should be fine. will post up some pics and more info soon i didn't take many as i wasn't going to do a build thread but thought id share it since if you search rb25de s13 all there is is hate about it and people saying its a waste of money.... well this build has cost me around 3k including car, rego, engine, gear box, edu, custom loom, full hard race arms, add roughly 1000-1500 for coilovers and its under 5k for everything. oh and I'm a panel beater so ill be painting it millennium jade free of charge, so to me it seems like a pretty mean streater under 5k and when the time comes for a turbo everything is ready for an RBxxdet to drop straight in
