Two nice cars, but I daily my missile.

[jgauspohl]

any updates?

[twisted99s10]

its been a while. been busting a** to finally get this thing finished. since last update, i decided on a color to paint it, decided to ditch the body kit, changed the paint color, finished the body work, primed, wetsanded, and painting the door jams. currently take'n a break from finishing some final things, and preping it to be painted tomorrow. but ne ways, here are pics.























extra pics, these were before it was jamed and we were cleaning out the inside from all the putty dust.

[twisted99s10]

Finally got it finished-ish. Im in love with the car, so alot more is gona happen this winter. I'll be posting a list of future plans later. But anyways, here are pics.

Sealed and ready to spray.

Painted and cleared


All together, sit'n next to her sister


Do'n truck stuff.


And a few pics one of my friends took.

Very cool! It really turned out great.

[sx moneypit]

Looks good man!

[s13sickboi]

I love the sight of s13 taillights with the hardbody rear window This is killer awesome

Whats that color?

[IanS]

Interesting.

Truck looks badass, but I am more interested in the motor. How is the power delivery? What are you tuning with? What intake manifold, if any did you decide on, and Which cams did you end up with for duration 248 248?

[twisted99s10]

thank you, and its "medium brown" off a 1988 chevrolet pickup.

i have run into a few hitches with the car. slightly before 250 miles the head gasket went. blew a hole from the 4th cyl to the water jacket. not really sure what caused the failure, but it was just slightly after i started reving to 5000 rpm before shifting. to solve the issue, the head is back at the machine shop for pressure testing and resurfacing, and i ordered arp head studs and a metal cometic head gasket. before the head gasket went, i did take it up to 6500 once, and i am amazed at the difference between this and a stock ka. for the cost of building this engine, and the little effort involved i am extremely happy

i have spent the last 3 nights researching and measuring suspension design. there is alot about to change on this chassis. alot of wheel well clearance, and alot of custom one off parts are in the design stages. stay posted for updates, there will be alot of them.

[twisted99s10]

im currently untuned. stock injectors, stock ecu, and running ridiculously rich. the maifold is stock, just a port/gasket match. the 248/248 is a hotswap cam setup. its putting an exhaust cam on the intake side. if i remember correctly, you have to turn the timing mark 4 teeth counterclockwise to get it to fall into time correctly. if you search for hot swap cams there is a post with a whole bunch of combinations, and how they react.

my goal for this year was just to break in the motor, this winter i'll be doing itbs and tuning with megasquirt.

[twisted99s10]

oh, as i said above i only took it up to 6500 once, and it was after the head gasket had already started to leak in the 4th cyl. you could feel the power band really hit at about 5200, and it pulled solid untill i let off the gas. im hope'n to have the new gasket in, and the motor back in the car monday night so i can get a few more days of drive time on it before the salt hits. im really curious to see how this motor performs when i can use its full power band.

I know all about hotswapping. I was just wondering which combo you went with. 248 248 was my guess.

I am in the process of building a similar setup for the rally car, although I am shooting for more useable power.

Do you think pre detination could have caused the hg failure?

[twisted99s10]

I think the headgasket was most likely dented around the ring when i put it together. Was my fault for not thinking to check it.

[lexcrob]

Awesome build!!! I love the paint job guessing your a body man by trade. Always wanted to hack it but im not much of a fabricator. As far as the "hot cam id look into breaking out the degree wheel while you got the head off. Seems there is MUCH power to be made from 248 248 that has yet to have been documented at least! Couple here-say that 160-170 range is made by tweaking 3 1/2 retard on exhuast cam if i remember right drilling cam gears and all that dark magic stuff.....

Anyways best of luck ill be starting my budget project soon 300$ hatch same story over here motor 50% 4 35% 3 22% 2 14% 1 leak down results of the night. LET THE BUILD BEGIN .....yet again!

[lexcrob]

Then again i noticed you said megasquirt and if you can get one of those set up ....well you need no lesson in degreeing cams or making power. GENIUS it takes to build one much less make it run*

[OutToWinPAHC]

What are the specs of the high compression build?

[twisted99s10]

I have looked into re drilling the cam gear on the intake, just not something i have done yet. perhaps something to look into further. Hopefully the megasquirt wont be an issue, im pretty fluent in wiring and i have a number of friends that have built and successfully tuned with the system.

OutToWin: what specs are you interested in? What parts are involved in the build, or what the final numbers and compression ratios are?

*Update*
The engine is all back together with ARP headstuds and a Cometic metal headgasket. I have been reluctant to put it back in the car, because it will be removed again to tub out the front fenders this winter. However after waiting 3 weeks for the snow to come, i have decided to put the engine back in and continue the break in process until we finally get salt on the roads. Below are some pictures of the motor removal/install, and some pictures of modified Chevy s10 xtreme sideskirts that i modified to fit the nissan. I think they flow nicely with the pig lip, and will work well on the car once they are 100% finished.

Just got a box in the mail the other day.


More Progress Soon.

[-RJ-]

oh boy

[pj]

damn man, the body and paint turned out awesome on this! i never had the guts to do a truck to my s13. this thread makes me really wish i did.

[alms24sebring]

wow I forgot about this thread. I gotta say, it turned out really good so Ill give you props for that. Great paint choice too.

Pulling the motor on a freshly painted car looks scary. Hope you get everything fixed and running well.

[twisted99s10]

Thanks guys. Tonight I spent most of my time try'n to get the thing running again. Just wanted to make sure everything was still good and legit after the headgasket, however I havnt been able to get spark. So far I have checked all my grounds and engine harness plug-ins, tested the ignition coil, coil to dizy wire, ignition chip, and the wiring for the coil, and the ignition chip. The dizy fires the injectors, and from some quick internet searching that tells me the dizy is working properly. This leads me to believe there is a broken wire somewhere, or something really obvious that I'm just not seeing. Either way I dont know how much time to spend on it since it will all be replaced when I go to the megasquirt system.

On the other end of the car, I dropped the rear subframe and took measurements of the rear toe rod and traction rod so I can purchase parts to remake them out of hyme joints and threaded aluminum bars. Since not much happened tonight, I didnt snap any pictures. If more awesomeness happens tomorrow night I'll show off the progress.

[lexcrob]

Injectors but not spark huh..

1)Check all the fuses if you didnt ***
2) alldata says ---there is an ignition coil relay
3) low oil pressure sender plugged in not shur on that
4) ECCS relay (remember it was sketchy when i was wiring my rb20det FAIL)
5) the little capacitor ground thingy mounted on or over by the coil pack if external plugged in?
6) make shur ur battery is fully charged(weird things happen) and its ground is also in good contact chasis/and or engine


Figured id brainstorm for ya!

Im locked in to see pics of the hyme custom rods?

[twisted99s10]

Well, just came up from the garage. Still not running. Completely went thru the fsm, as well as taking your ideas (lexcrob) into consideration and still nothing. For the moment in time, I give up. I dont know if I have been looking at it for so long that I just can't see the obvious problem or what it is, gona try to get one of my friends to come over and take a look at it this weekend.

So, after that I went back to the design project. Im going to kind of photo dump here, and try to show my plan. On my red 240, I already have the PBM Max Angle Kit installed, and as with most people running it I have massive clearance issues. The most difficult to correct of those issues are the tension rod, and swaybar contact. This is going to be my attempt at it. I am going to use a panhard bar mount piece that is sold by Bicknell Race Products (http://www.bicknellracingproducts.com/) This is where we purchased every piece for the sportsman modified i used to race. all high quality aluminum bracketry that is designed for race conditions.

this is a very quick illustator design of my plan for the front control arm, sway bar mount location, and tension rod design. As I actually order the parts in I'll post up part numbers and places to order the pieces from.

Anyways, this is the design.


Picture of where I am hitting on the red hatch.


Few pics of the space it will clear up.




Here is the bracket itself


Now, if tha all works, my next dilemma will be the sway bar. On the truck, there is slightly over 1.5" of clearance between the oilpan and the sway bar. If i move the swaybar 1.5" it should move it completely out of the contact zone. Below is a picture of the available space to slide the sway bar back.



This will mean relocating the swaybar mount location on the lca, but shouldnt be an issue, even if you are modifying an aftermarket one. as long as you have access to a welder and a way to cut metal you should be in business.

Kindof un related because i plan on changing this design on the truck, bu this is the tierod setup on the hatchback. its an example of how im going to do the hyme joints on the suspension arms.


This setup is extremely durable. I can drop the wheel off the track with no worries of bent tierods. At a track day some one clipped a corner to close and pulled a tire out onto the track and I hit it with the left front wheel mid slide. This would have undoubtedly bent a standard tierod, where as with this it didnt change the alignment at all. The downfall to this design was how far it moved the inner tierod pivot point out. it is fine for track use, but on uneven surfaces it drastically increased bumpsteer.

oh... and this is what i got accomplished last night.

yeah, lots of nothing basically.

[twisted99s10]

I have what I believe is a final parts list worked up for the suspension arms. This includes everything for the rear toe arms, rear traction arms, front tension rods, and front lower control arms (less the steel plate for brackets, and ball joint assembly still working on a plan for that) total comes to $260 even shipped to my door. That is 1/2 the cost of just a LCA setup thru PBM. Before I post a complete parts list I just want to double check the bar lengths one more time.

[twisted99s10]

Small update. Last night I got the car running. After checking EVERYTHING I put in a spare ecu one of my friends had... Fired up instantly. No idea what caused mine to go bad, but oh well. It runs now. Then I started marking out what needed to be clearanced in the front. PIcs of that once i start cutting things.

Today I took a roadtrip to pick up some new wheels. Rota D2's 17x9 et 15. Pics on the front below.


Some of the current wheel collection.


More updates later/tomorrow. Depends on how motivated I get this evening.

[twisted99s10]

The nearly complete collection. Still a few unpictured.

[PANDAemic]

Want to sell me some for cheap

[95zenki man]

looks good man keep up the good work!

[lexcrob]

I cant see the pictures!!!!!!

[twisted99s10]

Just upgraded to pro on photobucket so i wont have any bandwidth issues. Pics should be working now.

On my way to the garage now to put in more work.
