Hster time attack build 180sx SR
As of 3/20/2018
https://image.ibb.co/iU91Sx/1521560034826.jpg I will keep this super simple. I'm basically on a journey to build a reliable/fun street class time attack car. First goal is to beat my track times set with a e46 m3 using same tires : Hankook RS3 255/40/17 SOW 1:27.1 BW 13 2:04.1 --------------------------------------------------------------------------------------------------------------- https://s3.amazonaws.com/static.fixp...psx1muelpy.jpg https://s3.amazonaws.com/static.fixp...pscwpcb17v.jpg April 2015 shell purchased https://s3.amazonaws.com/static.fixp...psvkukhg9x.jpg https://s3.amazonaws.com/static.fixp...ps0dgutrok.jpg https://s3.amazonaws.com/static.fixp...psulqytdc8.jpg May 2015 Engine in https://s3.amazonaws.com/static.fixp...psigp7vvr7.jpg May 2015 First drive to gas station.

Couple of friends helped me paint for first time. looks half way decent https://s3.amazonaws.com/static.fixp...psp9ih09qb.jpg Oct. 2015 Went to adams motorsports parkway several times to shake down the car. got decent time. running stock s13 sr engine with Hankook Rs3 255/40/17 and megans track coilover Nov. 2015 Went to adams on drift night because I really wanted to crack my bumper. :facepalm: That's probably the first and last time I will drift with this car.. https://s3.amazonaws.com/static.fixp...psgqzifx8p.jpg https://s3.amazonaws.com/static.fixp...psuqfp4vaj.jpg Jan. 2016 Found out stock head gasket was bad. upgraded to t28/ 555cc/ JWT Ecu https://s3.amazonaws.com/static.fixp...psj0hddqik.jpg Mar. 2016 Upgraded coilover https://s3.amazonaws.com/static.fixp...psjfpyizxe.jpg https://s3.amazonaws.com/static.fixp...pszljatjam.jpg https://s3.amazonaws.com/static.fixp...pstsqjrwav.jpg https://s3.amazonaws.com/static.fixp...pstyj0fryd.jpg Mar. 2016 Along with t28, I wanted to keep myself safe at the track.

Apr spoiler https://s3.amazonaws.com/static.fixp...psiuhdlj2g.jpg May. 2016 Went to SOW. I expected little better time but I found whole lot of issues that needs to be worked on. Thanks for reading. will update as new things happen. |
Biggest thing I wanted to fix was corner exit oversteer and excessive roll.
I bought some whiteline sway bars to install before the next track event, but did not received them in time. https://s3.amazonaws.com/static.fixp...psbmerhqn2.jpg June. 2016 Auto Club Speedway (ACS) Roval https://s3.amazonaws.com/static.fixp...psl6juufcd.jpg The day started fine but after revving high on that bank, oil started shooting out from valve cover. I think the ebay catch can I have was too restrictive. https://s3.amazonaws.com/static.fixp...psq6poh40y.jpg three downpipe bolts decided to shoot out after continuous heating/cooling/vibration. had to tow the car home :-/ Best time of the day was 2:03.8. Still have a lot to improve. hopefully I can get my sway bar/ oil catch can in by next track day. |
Are the door bars constrictive? I noticed that you maintained complete door panels so that puts the door bars close to your body. Does it bother you at all?
I want to keep my door panels too and am debating whether to do it like you did or not. |
installing the factory oil separator or utilizing a s14 SR valve cover will help with pushing oil. These engines like to do that without either or.

1 year in the game...

Been going through some personal stuff..
need to do the following : - buy new set of tires - install sway bar - install jwt s3 cam/gt2871r - fix oil catch issue once I get the tires, I can rock the new wheels! https://s3.amazonaws.com/static.fixp...ps9sogmixc.jpg |
Damn, this is cool! Keep it up man
|
Awesome stuff. I think I saw you at ACS at the last Nissan Challenge event.

Getting ready for ACS Roval (California Speedway) 8/13/2016
https://s3.amazonaws.com/static.fixp...psnyy2mm9h.jpg Changed water pump pulley https://s3.amazonaws.com/static.fixp...psrmdxxbbj.jpg Added stock oil separator to see how much better it is. If this doesn't do much, I'm gonna have to modify the valve cover https://s3.amazonaws.com/static.fixp...psfbbljcbp.jpg Added whiteline sway bar on the front. When I installed both whiteline fr/rr, car oversteered just as before. I ended up with 27mm front and 15mm on the rear. Hopefully this setup works better. Is anyone else going? I think there is nissan challenge this weekend. |
regamasters yummmm
|
Swaybars made a big difference?

I went back out to ACS only to find more trouble.
https://s3.amazonaws.com/static.fixp...ps4wxx76n8.jpg First session after warm up lap, my intercooler hose blew. No big deal, just clamp it down tighter and go out on the next session. Session 2: as I finish my lap 1, car started to lose power. I look at the temp gauge and it was pegged hot. I try to pull over to a safe area but car eventully died and never started back up.:facepalm: Looking back, I think my timing was set wrong (on retard) which caused my engine to run hot. Once it got hot and built pressure, one of my radiator hose clamp was not fully tight as all of the coolant leaked out. I verified this by pressurizing coolant system. compression on cylinders are 90-90-90-20. probably seized the piston as well. It's all my fault. having a warning gauge would have been nice in retrospect. I'm gonna try to figure out where to go from here. maybe another SR or VQ. Definitely planning on keeping the engine stock as possible. https://s3.amazonaws.com/static.fixp...psjaqddauh.jpg |
New Journey begins with built bottom end.
Hopefully this engine will stay strong. https://s3.amazonaws.com/static.fixp...pstux5bh0o.jpg |
An EMS that has some failsafe procedures would help a lot probably in extending the life of the engine when you can't keep your eyes on gauges.

Awesome build!

I was actually talking to a buddy that has set of defi gauges with warning lights for his car and he told me he saved his engine one time from oil starvation. I always thought they were waste of money.. time to change my mind. Quote:

Yeah. I went with an infinity myself it'll shut down the engine for me if anything goes out of WACK.

https://s3.amazonaws.com/static.fixp...psz9khsd65.jpg Managed to pull the motor out https://s3.amazonaws.com/static.fixp...psxwkpares.jpg Found this! looks like it was resting against the turbo. Perhaps, that's the reason for overheating... https://s3.amazonaws.com/static.fixp...psklz7mkcn.jpg Upgraded the hose from nylon braided to steel braided with heat sleeves. https://s3.amazonaws.com/static.fixp...psdkw21unj.jpg Mounted gt2871r https://s3.amazonaws.com/static.fixp...psjtvcreqz.jpg Safety wired the elbow https://s3.amazonaws.com/static.fixp...pscjz5d57d.jpg Ogura for added power https://s3.amazonaws.com/static.fixp...psdcyph4kd.jpg Changed trans front seal along with couple gaskets https://s3.amazonaws.com/static.fixp...psja2bovjh.jpg Got the motor back in Still need to do alot more, but hopefully car will be running soon! |
https://s3.amazonaws.com/static.fixp...psmipdcyri.jpg
Finally started the car back up. https://s3.amazonaws.com/static.fixp...ps8x28tv1e.jpg Had a welder weld in some bungs and intercooler pipe https://s3.amazonaws.com/static.fixp...psvydzcgdt.jpg https://s3.amazonaws.com/static.fixp...psudbpudsj.jpg https://s3.amazonaws.com/static.fixp...pslor0nhi7.jpg https://s3.amazonaws.com/static.fixp...psffob40dw.jpg compression were all good some more minor work and it will be ready for shakedown! |

Swapped the valve cover with modified crank vent.
https://s3.amazonaws.com/static.fixp...pscvc9s63d.jpg https://s3.amazonaws.com/static.fixp...pson7cue3j.jpg https://s3.amazonaws.com/static.fixp...psx8gfngfj.jpg I got the idea from slider2828's thread but I believe I can use the rear port for crank vent, kind of like s14 setup. S14 valve cover definitely has advantage with sloped rear to push fluid towards the front vent but I believe this setup would work too. If it doesn't do the job, I would have to source a s14 valve cover. This is cheapest method so might as well try. I will report back after getting the aem ems tuned. Looking for a tuner right now.. |
https://s3.amazonaws.com/static.fixp...psqrhoyqju.jpg
I opened the valve cover again to do the cam : jwt s4 Valve cover decided to crack. I think I over tightened the npt barb fitting. Luckly, I had an extra valve cover but I had to have my welder weld in a bung for crank vent hose. https://s3.amazonaws.com/static.fixp...psx1yxiywr.jpg I then took out the maf and put in gm 3bar sensor along with gm ait sensor for ease of tuning. https://s3.amazonaws.com/static.fixp...pstfn4afln.jpg https://s3.amazonaws.com/static.fixp...psluiqlfjc.jpg Wired up 6 sensors (4 of them had to be lenghtened like picture) for Defi advance ZD. Hopefully this will save me from engine trouble in the future (knock on wood) https://s3.amazonaws.com/static.fixp...ps9flvwdsv.jpg Mounted oil catch can and moved the intake down low. https://s3.amazonaws.com/static.fixp...ps0thgxmql.jpg Mounted gktech fan |
You'll love the S4 cams, best sr20 cams out there.
I like the safety wire method for the o2 housing. What did you do for the nuts for the turbo to manifold? Is it difficult to drill the bolts for the safety wire? |
Quote:
I used stock nuts and locking plate on the turbo to manifold side. I've had alot of problems in the past using aftermarket headers where those back out, but with stock manifold, it should be good. To drill the bolts, you just hold the bolt tight and use drill press. |
good amount of detail...

Bad news : piston edge melted from excessive temp. Chris @ Natural Aspirations is a nice guy and he is willing to help, but I would not go back to him for another tune. |

Update from SOW CCW event
https://s3.amazonaws.com/static.fixp...psngzvfa3v.jpg This time I went with Nexen SUR4 because I've never tried them and heard many good things. They handled great and did not get greasy as quickly as the rs3s. https://s3.amazonaws.com/static.fixp...pst9jds37g.jpg Arrived at the track and signed up for Nissan Challange. All of the work paid off and I had a problem-free day (almost) which is always nice. Ended up beating my M3 time and also won the nissan challenge class 2. :) I'm looking forward to next event! first I need to change my turbo gasket :( |

How did the bolts that were safety wired back out?

Out of 5 bolts that are on the turbo to elbow, only 4 were safety wired, one that was not wired backed out good couple turns. |
why are the bolts popping out like that?
|
I think you might be better off running studs with nuts instead of bolts.

With this car, it's always boosting and staying at a higher temp. (around 1000-1500 degrees Fahrenheit and above 4000 rpm for 10-20 mins at a time) On top of that, I'm shaking the car left and right going through the turns. This puts a lot of stress on all of the turbo parts. My turbo to manifold bolt loosening was actually caused by one of the broken tabs (oem locking tab) that hold the nut in place. I should have safety wired them looking back. Quote:
|
I'm about to have my turbo welded to my manifold... tired of this shit,.
|
I've never gone through one of the turbo-to-manifold gaskets... I always use new hardware and put everything together off the car though. Usually putting a wrench on it and then hitting that with a hammer to lock it down @ 83 billion ft lbs does the trick.
|
Good to see another fellow S-Chassis out there going against time! Great job so far, keep it up. Maybe one day I'll take the S14 Time attack car out there.

OHLINS!?! How do you like them? I'm really jealous, and i hope your event at Laguna Seca goes well!

It was $120 for the Inconel studs and Stage8 lock nuts from FlyinMiata. They don't sell the studs separately.

I'm following this thread. I need to make a splitter to protect my bumper not so much for performance.

Hi, I just wanted to let you know im your new biggest fan. I could have warned you about the 4 turbo to manifold nuts being the #1 issue. After years of troubleshooting my only option was to safety wire, but when I had my turbo out last time I didnt even want to try to figure it out I decided I will just weld them together next time they come apart. I cant wait to see you at the next Nissan Challenge event. I saw your car up close at SOW but I had not seen your build thread til now. Woooo. I love 240 time attack builds done well.
|
Stage 8 fasteners seemed to have kept my turbo attached for a few track days now.
The big thing is running that bracket from the downpipe to the transmission mount/crossmember and taking weight off the turbo. The next time I have to take it apart I, too, am just going to weld the turbine housing to the manifold and call it. |

I used liquid nail to hold them together. I used aluminum square tube to save weight on the bottom and welded some steel tubing to the bash bar. https://image.ibb.co/kyDFVF/20170108_163301.jpg https://image.ibb.co/myPNAF/20170108_163314.jpg stood on it to make sure it will handle the downforce. I tore the middle of the panel and it started spreading so I reinforced it it with aluminum plate and carbon plate on top. Maybe I can use it for gopro mount in the future. |
Final prep for 22nd @ California Speedway!

Finally a track day!!
ACS event was cancelled due to rain.. https://image.ibb.co/cKeB4a/20170211_133658.jpg https://image.ibb.co/nBFjPa/20170211_140343.jpg Little hiccup going to Chuckwalla. tire tread decided to chunk off. My fault for not checking the age on it. Guy that sold me the trailer said they had "new" tires. :ugh: https://image.ibb.co/hmdhAF/20170211_171756.jpg Spent a night at this mansion. :) it was actually really convenient and comfortable. https://image.ibb.co/fjnW4a/20170212_111040.jpg Love to own a GTR! I'm hanging on to 4th gear because it popped out on me a few times. I also forgot to take my camera so was borrowing a friend's gopro. Can't really see the track on this vid but hope you enjoy it. Overall, car gained lots of grip in the front with the splitter and has a lot more neutral steer than before. Car started getting little hot as I pushed it more. I need to work on that and swap out my tranny :-/ |
It was awsome see your car in person and watching it perform out there. It inspired me to do more with my car. Hope to see you at the rest of the Nissan Challenge events. Am the guy with LS 240sx by the way.

.................................................. .................................................. ....... So I found out why the car started getting hot (highest of the day was 235degree F). I pressurized the cooling system and found puddle of water below the water pump weep hole. It was a brand new s13 water pump so I'm not sure why it failed.. Good thing I had defi warning! it saved my engine.. https://image.ibb.co/cUEuPa/20170219_125309.jpg S13 VS.

Interesting note : found the front cover cracked.. I'm guessing it's due to bad trans bearing. |
Who did your cage?
|
Quote:
Cage is pre-made cage by Enjuku. I had Ted (heliarc_hustler instagram) tig weld it for me. He does great job! My steering wheel is 330mm. (sparco 383). I personally prefer 330mm over 350mm. you can check it out at buttonwillow if you would like! |
I would advise against using a S14 pump on a S13 SR20. The impellers are designed differently and the S14 pump actually flows less when used on a S13 SR20 and does cause cavitation at a much lower RPM
|
Quote:
I would like to know little more in detail if you could elaborate though. I would think "flows less" mean that the impellers are smaller given same rpm between s13/14 engines, wouldn't that cause less cavitation? unless there's something going on inside the block.. or if the blade design is different.well, let me know! I will change back to s13 water pump if I have to! I do have bigger pulley so hope that it helps. I will report back after next track day! |
You were missed this week at button willow. I know you were planning to show up. Hope you make it to April first event.
|
Quote:
Look at them side-side. The details are not immediately apparent. |
Yeah I honestly don't know where the misinformation came from saying that the s14 pump was better for s13 engines, I've never bought into that myself. It's better to retain a s13 pump but run an oversized water pump pulley instead to slow it down slightly.

I wish I read a little more before purchasing the s14 pump. https://image.ibb.co/kMoPqF/1112161602.jpg I was having my car tuned over the weekend and we saw some knocking around 4-5000 rpm. We had to end the session early. Looking back, I'm wondering if the water pump may have caused problem somewhere and brought the cylinder temperature up.. Coolant temp was fine. Regardless, I'm changing the pump back to s13 one and going over the car to find any issues. |
Nice work man, good to see the 240 chassis used in other forms than simply drifting! (My username is just a joke I don't drift lol)
|
how do you like that enjuku cage?

What fuel pump are you running?

No my times kinda suck but I am out there having fun and learning. April 1st at willow springs. :2f2f::2f2f::rawk::rawk: |

Few people were telling me to upgrade to s15 water pump recently too. I still have the s13 water pump but sucks knowing the s14 pump could potentially be bad for s13
