Will's SR20 build (56k no no!)

[x240xdrifter]

So finally I have gotten my hands on an sr, its a s13 blacktop shortblock with everything but the following:

alternatorfuel injectorsflywheel and clutchtransmissionexhaust mani and downpipeturboengine harness and ecu

Onto the Pics!



thats on the stand partially torn down, I'll be tearing it down completely and rebuilding it from the top, phase 1 of the build will be all new gaskets, including a metal headgasket and arp headstuds. I got s14 pistons and connecting rods, and new bearing, rings of course, and so forth. started to tear the rest of the block down, pictures soon to follow. The goal with this setup is to have between 250 and 300 whp, its my daily driver, and I want it to be realiable and driveable. I'll also will be upgrading the turbo to a t28. I got alot of work ahead of me but i couldnt be more excited, keep posted for updates, and suggestions and so forth are welcomed!

Dirty motor. I see a hot tank in the near future.

you better believe it, dont worry, I'll take good care of her

[S14toRPS13]

Looks like a fun project. That's one of my goals that I haven't done yet. Rebuild a motor from bottom up. 250 to 300 whp is good for a daily driver, but it does leave you wanting for more after a while. Then again if I was making 350 whp, I'd probably want 400 and so on.

I know you will.

Keep an eye on the classifieds to get the rest of the components for the motor. I literally pieced my new motor together from part outs on NICO and eBay. And all I started off with was a block (no head), crank, pistons, and oil pans/timing cover.

Better yet, a bead blaster.

[Hijacker]

Definitely the best way, Ryon. The machine shop working on my motor didn't bead blast my block because they were afraid they'd get the beads down into blind oil galleys and the head stud threads. That's why man invented aluminum colored engine enamel I suppose.

[x240xdrifter]

thanks for the replies, ya I am very excited, its hard to contain. I have many good friends who will be able to help me source parts, as well the good family here and who could forget ol' ebay haha. If possible, I would like to have it all said and done around 2 grand, however we all know, when we get deep into projects like this, our orginal budget might, shall I say get over extended haha. My biggest concerns, or expenses are the turbo and transmission/clutch. Deff. going to have a t28, not going to bother with a t25.

just some footnotes:

-gotta replace every possible gasket and seal- must have a t28- my driveshaft is a bit off balance, so I'll probably invest into a one piece- probably going to go with a spec stage 1 clutch- Must run Greddy E-manage Ultimate- I will probably run a manual boost controller, then when money allows in the distant future, switch to electronic- debating whether or not to do a MAP sensor

......more to come of course

[jspec603]

Well if your planning on running the Greddy EU, you can just get a pressure sensor as an add on which will all Giles to tune it like a MAP. That way you'll have the best of both worlds. As far as you getting/needing parts, don't forget that I got your back! Along with James, Dan, Jake and Tim...wait not Tim, that's an FC. And please don't buy a Spec clutch, I personally have not heard many good things about them.

[x240xdrifter]

ya I was planning to run a pressure sensor on the emanage and have giles do the tune. I know you and james and dan and the whole fuji spl crew gots my back, and I appreciate it so much, you guys rock as always. I'll stay awao from spec, only reason was the price, I am a big fan of exedy from personnal experince and I'll do it again. full gasket set and HG will be order soon, as well bearings and rings. As soon as I strip the block completely. I'll send it out to get hot tanked. I have place that will do a custom 1 piece driveshaft too, I just got to bring it in

[x240xdrifter]

so another quick update; went down to continue stripping her down. Today I removed the main caps and pistons and the crank, aswell all the knick nacks on the side of the block. cyclinders look to be in good condition and just need to be honed. The 3rd cyclinder spun a rod, and all the oil was very sludgey and you could tell they were running a bit rich haha. Some coolant seemed to be mixed in too. however I feel like I need not worry, the crank had no endplay, and inspection of the crank; there was no signs of concern.

Heres the bottom end, waiting for disassembly.

this was right before I started to rip it down today.

Heres the block with everything out



Heres the crank, looking good, except a bit rough on cyclinder 3, dont worry

the clylinder walls, will be breaking out the bore gauge to make sure everything is within spec

the block now

the front timing cover and related items off, as well the water pump. Will be getting s15 chain guides if possible, because they are steel rather then gay plastic. also the water pump looks to be in great shape.

closer pic

another shot of the block

heres the head,

the stock cams and s14 pistons and rods behind the block



So there you have it, a quick little update. I plan to get the crank mirco-polished and balanced within the week. and in a few weeks, the block will get hot tanked. The full gasket set, Metal HG, ARP studs, will be ordered soon. The bearings and rings are on hold till all the measurements come in. Thanks for tuning in! expect another picture update Sat. the 12th

[x240xdrifter]

its been awhile since I've had an update, but I have completely stripped the block down to just....the block, and getting it hot tanked tomorrow. I've also got my Blacktop SR harness and alternator in the mail about 2 weeks ago. Also picked up a starter and flywheel. The past Sat. I worked on the head slightly, started to take the valves out, but ran out of baggies so I had to stop short. Once the head is fully apart, it will be sent to be hot tanked as well. I'll also be getting the crank checked, micro polished and reground. Once this all has been said and done, I'll be ordering the bearings, rings, and headgasket, ARP studs, and so forth. Pics will come very soon

[Hijacker]

Looks good! That motor looks like someone never changed the oil in it. I haven't seen so much black sludge stain in a long time.

If you order your TC guides from Nissan, you should get the new updated metal guides.

Sadly it's pretty clean compared to mine

ya I was planning to go with S15 TC guides Ya this engine looks slightly abused, and it sucks, but hopefully everything goes smoothly at the machine shop. I'll ask them to check the deck surface to make sure everything is straight as the same with the crank. The block today is getting hot tanked and probably next week get the crank polished and reground. The crank looks brand new except obviously where cylinder 3 spun a rod bearing so ya, I hope all goes well.

so heres a question for you guys, I am shooting for about 250whp to 300whp. But if the desire is ever needed I would maybe go higher in the future to say 400 hp or so. Now in saying this, I dont want to tear this thing down again, so would OEM main and rod bearings handle such? or should I just get some kind of aftermarket bearings?

[Hijacker]

OEM bearings will hold up fine for 400-ish. However, you are going to be turning the crank to fix a spun bearing. Most shops that I've used have always mchined all the journals to make it uniform across the crank. Nissan makes undersized bearings, but usually it's easier to order a set from ACL (or your preferred manufacturer) and have your shop cut to fit.

when i do my next build up i willsend my block o mazworx to have it resleeved. and bored out . cause i would want some one with experience wit hthese things to do it.

UPDATE PICTURE TIME!!!!!!!!!!

sooooo I snapped some shots of the block in my room before the hot tank today, just to get some before and afters, you know. Well I picked up the block today from my local machine shop, and I am excited and very pleased with the results, $71 dollars well spent in my book. I had him check the deck for straightness and he said everything look great except he said you could tell that the guy who owned it before hand ran it with a blown headgasket as there is some pitting around the cylinder walls, especially on cylinder 1 and 4, he said I should be fine, as its not terrible and the gasket should seal and cover it but he said worse case scenario is they would have to shave it off if the gasket doesnt look to seal. anyways, on to the pictures!

Before:....drumroll please

AFTER!!!!





me likey

heres a pic of the pitting on cyl 4. dunno if you can really see it, my cam sucks, but ya I think I'll be ok, atleast I hope so

[x240xdrifter]

ok decided to go another step further and I did some quick sprays with some super high heat alum. paint just for the oh so fresh and so clean look, soaked the bolts that were on the block while it got hot tanked and I just put them back.





Yup you guessed it, Doggie approved cleaniness

checked the block/crank for the numbers for the bearings

The block has an oh so convient gash over the numbers but it appears to be:

block : F22222

Crank: 33222 1111 0225c

I know the whole coded bearing deal but since the crank is getting machined at the shop ( spun cyl. 3) we'll have to play the bearing situation by ear, I would really like to do ACL main and rod bearings. anyways, its a long and slow process, thanks gor tuning in!

[x240xdrifter]

Hey guys, I know its been a very long time since I've updated, and I apologize, but I assure you the process is still going on and strong, last update the block was hot tanked, well I decided to get it decked too, I just got the crankshaft back from being reground and polished, and I got the lower oil pan hot tanked. They surfaced and hot tanked the head, and they will be cleaning the valves/valve seats and a 3 angle valve job I believe. So everything is coming along quite nicely, and I have a handful of pics to share, so enjoy!

Heres the block hot tanked and decked, completely took off all the pitting, really looks brand new

Upper oil pan hot tanked

The crankshaft picked up from the shop

OOOOOOHHH shiiiinnnnnyyyyy

Good as new! .50mm on the rods and .25mm on the main

All the valves and stuff, including the Grex valve springs

so this stuff will be dropped off at the machine shop asap

I need to order some valve seals, rod and main bearings, and piston rings and I can start putting it back together I'll keep you guys posted!!!

[DJButton]

Very cool man, FUjii cars all going big! I'll probably bring the SR to that place as well, so far everything looks mint!

[tmonttt]

looking good man

[idahotuner]

i am very jealous right now. lol

i would like to finda short block to start building.

how much did you pay for that. ?

waht are you doing about the sleeves. are you boring it out or just leaving that the same.

[x240xdrifter]

the shortblock was 400 bucks from a good friend, and as far as the sleeves go, they will be left stock bore and honed. I wish I could afford darton sleeves and aftermarket pistons and rods. but for the time being I'm going to have to remain stock. Using s14 sr pistons for the extra oil jets inside the piston, but after cleaning them, i noticed some denotation marks on two of them, so i am debating if i should just clean em up and use them or get aftermarket pistons, stock bore of course. I'm not going crazy with the block, just cleaned up the internals, ACL bearings, S15 oil pump and cover aswell s15 timing chain guides (all steel). Metal headgasket, arp studs and so forth, it will be enough to hold up to atleast high 300 - low 400hp mark. The head is where all the magic is happening, at the machine shop now getting hot tanked and cleaning up the valve seats/valves. Greddy springs and 256/256 cams with rocker arm stoppers will make a pretty decent set up on top of that

[x240xdrifter]

UPDATE!: 9/08/08

My Gasket Set came into today, hooooray!!!

thank you UPS manCool Nissan BoxStock Headgasket, exhaust gasket, and intake gasket. FYI I'll be selling the HG and exhaust gaskets if anyone wants them Valve seals, Valve cover gasket, and all the little knick knacks for the head

I bought ACL duraglide rod and main bearings. .50mm for the rods, and .25mm for the mains. The head is almost done, I need to drop off the valve seals for them, and I'll be ordering a s15 timing cover/oil pump, rear main seal as other bottom end knick knacks im too lazy to spell out from my new job soon (yay for working at Nissan!) and shortly I should be starting to put her back together!!! soooo excited

[x240xdrifter]

UPDATE!!: 9/11/08

Just got the head back from my local machine shop And all i can say is holy crap!, I'll let the pictures do the talking

Fresh from the shopYou might be wondering why the #8 exhaust valve is missing the spring/retainer? well its cause I am missing a valve lock, so no biggie, plus side is, it will let you see the quality of the valve job Exhaust sideIntake side wow look at that!!!like brand new!, the cosworth metal headgasket is going to be one happy camper sandwhiched between that beautifully plained block and head hard to see due to the fact my camera sucks, but it is some quality stuff

So there you have it, this is shaping up to be quite a nice foundation for some serious power numbers while retaining reliablity

Pistons are getting cleaned up right now, and this thing can slowly be put back together! this is exciting, hope you enjoyed!

[DJButton]

Wow! I still can't believe this was going to just be a simple throw it in and run with it swap.
