First and foremost I would like to say thankyou for this awesome website, the search feature has been most helpful to me in my endeavours.

A number of years ago my then partner Fiona was in dire need of a daily driver, something reliable, easy to drive and maintain and attractive (girls are funny like that)

The search began...... classifieds, ebay and caryards and then we found her..... Silver 1984 MR30 Ti sedan factory mags, electric windows and mirrors and an antenna that that could be popped up and down from the roof console lol. $1000 dollars with rwc and rego.

This litle car was soo reliable and fun to drive, never missing a beat ......

Fast forward 5 years

I was replaced with a newer model and so was the little skyline, the years had taken its toll (on the car) and when i bought it from her and drove it home i checked it over, no oil in the motor at all and brown sludge was circulating its way through the cooling system and it had 6 different sparkplugs (i had no idea that there was that many different plug manufacturers lol) Basically the car had been driven into the ground. It needed a LOT of work

I thought about my options, so much work to be done to bring her back to her former glory was it going to be worth it? I couldnt bring myself to scrap her, but parts for this car getting so hard to find i decided to go the RB30 route.

What i had at first thought was going to be a couple of weekends work at most has turned into a lot more.

The L24 was pulled out and we had the RB30 sitting in place on the first day. Using the R31 engine mounts (mounts had to be slotted where the locator pin sits) and the original R30 gearbox mount (auto)

The whole motor and gearbox went in no dramas and matched the R30 tailshaft spot on.

Then we started on the wiring, this would be fairly straight forward I was informed..... Seems a lot of people have mates that know someone who knew someone that did it etc

Not the case as I have discovered. The whole loom from dash to headlights was removed and replaced with the R31 loom ECU, Tranny computer and time control unit. and six cluster dash. A few plugs had to be changed and extended, no biggie.

Retaining the original radiator using a range rover top hose. ( hose is on the other end compared to the R31 item and this one seems to fit perfectly)

Next all fluids replaced, battery fitted and tranny lever adjusted new exhaust fitted and it starts first turn of the key.

Now we run into a problem, the fuel pump wont stop and keeps pumping fuel while the ignition is on. Is it meant to do this? I was under the impression that the once it got to pressure it is meant to stop?

I'm thinking i may need to upgrade the R30 pump with either an aftermarket jobbie or work out how to instal the R31 intank item.

Thanks for your time, i'll try and upload a few pics this week and an update.

:)

Just a quick edit, we used the R31 power steering pump and the nice guys at enzed (pertek laughed at me and said good luck with that) made some new hoses and fittings to mate to the original power steering box, $160 well spent

Moderators, couple we eventually have this made into a 'sticky' as it seems to be a fairly commonly asked topic, but here is an excellent response!

    • Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels
    • Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)  
    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.            
    • Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.
    • Wow the colour matched hard top completely transforms the car. Are there any nice front lip options for the car or is that off the table?
