Motary's RS13 to RPS13 build

Hi, I am Siim and I am from Estonia. I study Automotive engineering in Tallinn University of applied sciences and this my build. The car started out as a bone stock 1989 Nissan 200SX with a CA18DET that I wrecked in a tight bend. Then I bought a new body and transfered the running gear and interior to it which resulted in this:

Since the CA18DET engine is very sensitive to proper maintenance they are all in terrible condition and done over 300 000 km and tend to suffer from spun engine bearings and poorly mended engines I decided to do a full SR20DET conversion with proper parts.

Clicky

Clicky

but as of right now I just need the engine mapped so I could get on with bodywork and drifting :p

Would have had it running today but I'm missing ONE flywheel bolt, buggers had seized and we had to weld bars on them to get them loose since the heads had become round :doh:

Was following your input in the uber suspension roll center etc thread. Do work! Subscribed.

I've been having some problems lately with my car since a fuse went, car takes like 2 minutes of cranking to start up and it runs quite rough, I have replaced the broken fuses, but this issue still haunts me. The ecu diagnostics shows everything is running okay, there is also a massive smell of fuel in the exhaust so I am guessing it is something in the ignition perhaps?

Been busy designing and fabricating new front suspension setup:

http://motary.planet.ee/200SX/012/comparison.jpg

I will also be making a new strut top mount to reduce the jacking effect and camber change:

Standard kingpin axis and caster:

http://motary.planet.ee/200SX/012/stock%20kpi.jpg

Modified:

http://motary.planet.ee/200SX/012/reduced%20kpi.jpg

Also made a temporary head shield until I can source the OEM one:

http://motary.planet.ee/200SX/012/DSC01844.jpg

The intake pipe is quite close to the manifold so I need to do some heat shielding there.

Had a friend fabricate an intake pipe to hold the Synapse diverter valve:

http://motary.planet.ee/200SX/012/DSC01855.jpg

It's crazy how fast it responds!

http://motary.planet.ee/200SX/012/DSC01857.jpg

Adjustable anti-squat:

Rear suspension as it is right now:

http://motary.planet.ee/200SX/012/DSC01150%20copy.jpg

I will be designing a brand new upright with some neat features for spring as my final paper project :p

glad to see you stepped up from cut springs lol looks good

Mason is that you?

I got my wishbones back from the machinist today, total mass per wishbone reduced from 5,1kg to 2,1kg

http://sphotos-c.ak.fbcdn.net/hphoto...35189654_n.jpg

whoa, this took an interesting turn for the better.

cray cray
cool build man

very very nice car dude.

I'm very interested to see how the front suspension works out. Solid build so far.

Wow dat angle. Cool build!

I ordered new overflow bottle from GKTech when they did their silly 9 dollar sale:

http://motary.planet.ee/200SX/2013/GKtechtank.jpg

It is much thicker than OEM and stronger too, but the hose opening is too big to properly hold it in there and overflow hole is smaller because of the thicker material.

It took some time but I tracked down what was the reason why the engine overheated, pretty stupid that I had forgotten to cut a hole for the waterway in the head:

http://motary.planet.ee/200SX/2013/20131006_163802.jpg

Correct gasket:

http://i.frsimg.com//images/detailed...t_S14S15_2.jpg

So I bought a correct gasket instead of making one myself that only comes off as rubble.

I thought I had a headgasket leak, so I had previously ordered a new from by Cosworth and ARP2000 headstuds with it:

http://motary.planet.ee/200SX/2013/20131006_164133.jpg

http://motary.planet.ee/200SX/2013/20131017_182114.jpg

Then I discovered the head can't be installed with studs in place, the chain guides get in the way. I removed the studs and installed the head:

http://motary.planet.ee/200SX/2013/20131017_230106.jpg

I did some heat shielding too:

http://motary.planet.ee/200SX/2013/20131008_203121.jpg

http://motary.planet.ee/200SX/2013/20131008_212252.jpg

And assembled:

http://motary.planet.ee/200SX/2013/20131022_153107.jpg

I have also been working on the new rear suspension:

http://motary.planet.ee/200SX/cad%20.../89%20copy.jpg

Looking good man! Excited to see this thing in action!

When I read the cut springs, I was skeptical but such great progress. Really like the DIY wisefad front set up.

The head can be dropped over the studs if you have someone there to help flex the guides a bit to clear. I've done it multiple times.

I couldn't do it, it got stuck.

Does anyone here have experience with Z32 mafs and Nistune? I can't get it to work right. The maf works fine on a z32, but when i wired to my s13 it will not idle, but will rev

very interesting build. definitely took a large turn for the better.

Are most of you referring to cut springs? It was an upgrade that cost nothing and slightly improved performance, the less threads the stiffer the spring.

Today I finally got the ecu and Z32 MAF to work together! Hooo!

Video

Subbing for double wishbone!

I can dream can't I?

wHOA - cool suspension stuff happening here!

good build man keep it up

Can you post some pics of the wisefab parts installed underneath the shock towers?
How do the upper struts interact?

nice, i love the custom lower control arm and tension rod piece
