I'm gearing up for the SR install this weekend. I have done as much research as I possibly can. I've tracked down all the random internet FAQ's and instructions, and even bought an ebay DVD.

the DVD by the way, isn't all that great, but it's definately better then nothing.

I'm aware of most of the major problems / modifications needed for the install to go smoothly.

I have the EZ install kit from heavy throttle, as well as a OEM sr20det radiator and SMIC, so radiator hose issues and IC piping shouldn't be a problem. And heater hoses should be fine.

I have a '90, so I'll be losing PS and AC, no biggie.

Now, the question is...

What are the small things you guys ran into, that noone ever seemed to mention, that ended up being a hassle for you? Or not even a hassle, but maybe something you think is worth mentioning?

I'd like for a minimum amount of suprises when I go for it.

Thanks in advance..

I'm assuming you have all that is needed to do the install. This is what happened to me:

Missing MAFMissing Ignitor chipFried ECUSeized TurboBroken Turbo outlet to intercoolerSaw Dust in coolant (no idea why)

One issue that might one for you in the future, is that my windshield washer fluid resevoir is no longer there, because my intercooler piping (FMIC) took that space up. Go figure. SO it sucks sometimes.

Timing might be an issue. GOod luck with that too. Mine is at 24 degrees..... I think the stock is supposed to be at 15, but the car runs like *** at that setting.

As far as the basic install of it. I think that the majority of the info I'm sure you have should do the trick.

Best of luck to you man. :D

yeah, i have a full uncut harness ( supposedly it's coming brand new, but if not, no biggie ), ignitor, MAF, ECU. etc.

Hopefully stuff that I shouldn't have to worry about, will come fine ( turbo, misc parts ).

I'm somewhat nervous to mess around with the timing of the car, but I guess I may have to just to get the car running and to a mechanic so he can do it right.

Couple things I can think of is a pin and wire for ECU pin #24 for your check engine light, I got mine from a 240 in the junk yard but im shure many nissans would have the correct pin. And since I wanted to modify the SR harness and not the KA one I got the connector near the main ECU connector that goes to the dash wiring so I dont have to hack my cars harness. I didn't get a turbo to MAF boot/pipe so I got one from a Stanza that looks like it might work.

you don't have to lose PS because you have 1990...swap lines from a 91-94 OR bend your 90 lines to fit (a suggestion by speedracer1 in other threads. i think)

I used the RHD 180SX high pressure line. Took 3 hours to bend without crimping, looks like crap, but it was free from a friend and is $350 cheaper than getting it from LS Automotive. Though I recently found a DOHC line at a junkyard for $40 so i'll be using that soon.

Swap all the transmission sensors and use the KA lower harness... most people don't talk about this... I still have no reverse lights because of this...

It's also easier to install the lower harness with the motor not in the car...

Oah and be sure you can get the oil filter off BEFORE you put the motor in the car! I had a hell of a time trying to get mine off once it was in there... i ended up inventing a tool...http://www.nissaninfiniticlub....t=oil

I was going to start a thread like this since I just got done with my swap. Like you I researched as much as I could for almost a year. Things that I find aren't mentioned much is that you need to take the lower heat shield off the turbo or it will hit steering coluom*. Also deff. connect heater hoses and brake booster hose before putting it in. If you are lifting the engine connecting the bolts on the side of the engine below the valve cover with a chain, do not connect any chains on the back of the engine there is no clearance( I had to take mine off and do it agian.) Other small things: dont put the oil in the trans until its in the car, dont put the downpipe on until its in the car, when putting on vacumm hoses and intercooler piping make sure to make clamps tight and after piping is in place try not to move it around, to help prevent boost leaks. When you start the motor up theres a good chance you will see some smoke, because during shipping the engines move around so much, mine smoked for about 15 min. I thought that my turbo was gone, also if you spill antifreeze/water anywhere on the radiator it can sit on it for a very long time. I filled my up and topped it off, came back 3 days later to finish it and start it up, it started and there was enough steam that I thought the rad had a hole, it steamed for also 45 min, total running time. Just keep reseaching its teh best thing you can do.

Also I had my wiring done by the guy on ebay, and other that the o2 sensor wires not being long enough, I havn't had a problem sense. Jason

This doesn't apply to many people but if you are swapping an SR into a Canadian 240 use the SR lower harness, it plugs right into everything.

I wish my car was canadian then. I'll have to rig up the wirng myself as I only have the SR harness.

quick question, how many connections near the main fuse box that are unused if you use the SR harness? I have 7 connectors near there and the SR harness has a total of 3 (maybe 4 but pretty sure its 3). I know there are supposed to be a couple un-used but it seems like an awful lot.

On the lower harness 3 plugs goto the fuse box, the rest goto starter, alternator and transmission. The lower harness also connects directly to the battery. Whatever plugs you have left hook up to the main harness.

motor mount nut was seized on jdm drivers side. had to torch it off.

oil pan dented had to hammer it out

forgot to drain transmission fluid what a mess on shop floor.

left intercooler cold pipe at friends house 1.5 hrs away had to drive to get it.

did clutch on the floor and took 1hr just to get the transmission back on the motor... real ***** to get it lined up and bolts started.

otherwise everything was there (full clip) took 24hrs (2 looong days)

speedracer1 if you come across anymore I'll buy one !!

what if I got my hands on DOHC power steering component's AFTER I put my SR in. Would I have to pull everything to install it? Or can I work with the motor in place.

it looks possible from what i can tell... You might have to do a little pushing and prodding but the PS lines go pretty mutch along the side of the car...

You can use the sohc lines like I did. But I found that the DOHC powersteering lines had a little bit better response. Something to think about. It wasnt that hard to change it with the motor already in.

Also Make sure you change your heater core lines in the back of the firewall and your turbo water line hose is replaced. Those lines are a "MOFO" to get to once the motor is in. I had experience with that and it is not pretty. Save your self some time and swearing. :)

Yup, i already took notes on that, and bought the heater hose's from heavy throttle.

Power steering lines are easy to install with the engine in the car. Though make sure you install the high pressure line before the low pressure line, or else you have to remove the low pressure line first. The system should probably be drained of ps fluid (PS fluid is actually auto transmission fluid) so that you dont have it dripping all over the ground. Also its much easier to install the ps lines with the car jacked up, and even easier than that with the wheel off.

As for heater hoses, too bad the S13 heater hoses arent more like the S14 hoses. S14 outlets are very easy to access even with the engine in the car.
