****************************************


I bit the bullet and finally decided to get a engine and attempt the SR swap. A couple of months ago me and three other people, who all have much more automotive mechanical ability than I do, pulled a KA from a hatch and got rid of it and pulled another KA from a coupe and swapped that into the hatch during a weekend. Participating in this swap was very useful in helping me to remove my KA and the knowledge that I got will be useful in helping me to perform my SR swap as well. After reading other peoples build threads I don't think I can call mine a "build" because I'm just shooting for the bare-bones basic SR swap. I plan to swap out as many gaskets as I can, the front/rear main oil seals, waterpump, thermostat, spark plugs and possibly add a few aftermarket parts over their stock counterparts. If somebody sees something that I am doing wrong by all means chime in because I need all the help I can get.

!!!!ADDED A QUICK TABLE OF CONTENTS FOR THOSE WHO DON'T WANT TO WASTE TIME SEARCHING THE ENTIRE THREAD FOR THAT ONE PIC OR ANSWER TO A QUESTION...IT'S ON PAGE 24...COULDN'T PUT IT ON THE FIRST PAGE SORRY!!!!!!


I got my engine in from JSA Motors. Everything was intact, no missing pieces or parts(MAF/Ignitor chip), no broken crank angle sensor and a complete uncut wiring harness. Shipping was swift and I was able to track it to my delivery point. My only complaint was that the block was a little grimey, they said they would clean it before strapping it to the skid.

S13 Redtop SR20DET

The transmission is intact and very clean...

no transmission crossmember but I can use my KA's crossmember.

First thing I did was bust open the valve cover and inspect the internals, during my research I read some horror stories about people getting engines with rust and dirt inside. Apparently someone wasn't too fond of oil changes.

After that I completely broke down the exhaust side of the block. Striped everything!

Did the same for the intake side.

I removed the alternator, P/S pump, A/C compressor and the belt driven fan.

Broke out the bucket O' water, scrub brushes and Mean Green and started scrubbing away but I got tired of killing my back working on this engine on that old tire....

and borrowed a buds engine stand. This thing is a life saver!!!!!!

Look at all the stuff I pulled, hope I can remember where everything goes when I try to put it back.

After cleaning every knookie and cranny on this block I taped off everything I didn't want to get coated and laid down a couple of coats of high heat iron cast aluminum engine enamel to the block.

Turned out better that I thought it would.

How come you didnt mask off the valve cover when you painted the engine? Gonna powder coat it or something?

Yeah, I'm gonna powdercoat the valve cover but I should have taped it off anyway, just got lazy and impatient.


Now that I had everything cleaned up I turned my attention towards replacing parts. The first parts that I attempted to swap out were the main oil seals. I read up on what should be changed out on any basic engine swap and the oil seals were at the top of the list among other things such as oil pump, water pump, thermostat, spark plugs, various gaskets, motormounts, oil pan, etc.

FRONT OIL SEAL REPLACEMENT

Tools needed:
Socket wrench
Socket extension
27mm socket
Chain
1 transmission bolt
2 flywheel bolts
Pulley puller
Breaker bar
Seal puller or prybar/screwdriver
Seal driver

I want to change out the front and rear main seals but I can't get to the rear with the engine on the stand but the front is accesible. To get to it you need to remove the crank pulley but I couldn't get the pulley bolt off because the crank kept spinning when I tried to man up on it and I don't have any air tools so I had to think of another way. I decided to use the chain and the links that I used to pull my KA to help me.

I put two flywheel bolts through the chain and threaded them into the crank.





I looped the chain around the engine stand, stuck a transmission bolt into the link and threaded that into the transmission housing.

This kept the pulley from spinning.

This allowed me to use my 27mm socket and breaker bar to bust the crank pulley bolt loose.



Now I just need to get a pulley puller from the parts store to pop it off so I can replace the front main seal.

Here, you can see the rear main seal that I can't get to yet. Anyone know how it comes out? Does it pry out with a screwdriver or something?

for the exhaust manifold gasket. use an 02 sentra with an sr20. that is the best exhaust manifold gasket you can get.

use lock washers on the exhaust manifold also to make sure it's sealed properly.

carquest sells heater hoses that work perfectly for $20 to route your heater core piping. if i can find the part #s i'll post them up.

part# from car quest to get the heater hoses:

19628
19619

Thank durdan on the forum for the info.

Thanks but I already have a set of heater hoses and an exhaust manifold gasket as well. I will get the lock washers as you suggested. Quick question though, since I plan to stay stock I wouldn't see any benefits from upgrading the intake manifold from the OEM manifold to an aftermarket manifold would I?

OEM Intake Manifold


Today I took my intake manifold apart and cleaned it up. I'm gonna replace the gaskets and maybe the IACV as well.

Broke it down, intake runners, intake collector, IACV(idle air control valve) and the throttlebody.

The first thing I did was clean up the throttlebody...

It was pretty dirty.

Cleaned.

I'll replace the throttlebody gasket when I put the intake manifold back together.

The intake collector was full of carbon buildup.

I got some brushes and cleaned it out pretty good too. I'll replace the intake collector gasket as well.

The IACV.

I can't decide whether or not to clean this up or just replace it. I came across a write-up on how to clean one but I can't find it again.

Carbon build-up.

Got some new hoses to replace the ones on the intake manifold.

i'd stick with oem. until you're really need something more. the more factory parts in a motor the better it runs. the intake manifold won't make any huge difference. i hear the greddy manifold gives more mid rang power by sacrificing a little on the low end. i don't know how accurate that is, since it's internet information, and as far as i'm concerned it's right 30% of the time.

You're doing a great job on this prep. I did some of the stuff you're doing. I didn't take off the manifold and take it apart though. My only concern would be putting it back together, and not having any air leaks. all those places would be a place you have to check to find vacuum leaks if you have any once it starts running. I understand why you did it, I'd probably go the same route, just make sure you torque it down properly. I did clean up tons of bolts during my prep, and I never forced anything down.

The heater hoses I listed for $20 are the ones Enjuku sells for $40. I hope you didn't get a copper exhaust manifold gasket, if so get the oem I listed. All information passed onto me when I did my sr swap. Now would be a great time to drill that exhaust manifold for an EGT gauge or wide band o2

My sig should have a link to pix for my swap.

Could you use a little RTV or something when you put it back together?

rtv could work. i'd probably just use new gaskets. if they weren't found then use rtv.

I checked out Project Eva, excellent pictures of Bumnah's swap, also very useful. I saw some things I haven't seen before.
