Use some kind of degreaser (purple power or something) and a parts washer brush for the edges/corners. If you intend to paint you will also want to wipe it down with some powerful solvent before painting. Usually there is a "prep wipe" to use while the car is sitting in the paint booth right before you spray it. It sounds like you intend to rattle can it though, so do not overlook this prep step.
BIG RAJAH!

I opened up the intake manifold and to my surprise, it was oil free I think its just right behind the throttle body. But the exhaust side of the head does look dirty.. New head gasket is and valve cover gasket is going be another big chunk of change my student wallet doesn't want to pay LOL I'm thinking I'll throw in a new intake manifold gasket and call it a day, what do you think?

Yes I'm missing that rubber boot, I wonder if the OEM one fits the aftermarket short shifter.. I would be open to getting a totally new shifter assembly but my wallet does this, LOL. On a good note, I believe I found the culprit! The bushing that connects the shaft ball thing to the transmission has a lot of play. I'm gonna try to replace this and see how it goes.

Also, keep in mind the mating surface between manifold/turbo will require a STRONG SIGNIFICANT cleaning, it took me almost an hour with a wire wheel (a big, high speed industrial wheel) to slowly work the carbon buildup off the surface. You would be surprised how much is there, and how it can look like metal but is in fact a carbon sheet.
Thanks for the tips, will do for sure! And yes, I already got all OEM new exhaust side gaskets and I'm about to order all new nuts, studs and bolts for exhaust side stuff and transmission.

Got it! Kingtal0n, thanks so much for taking the time to help me. It is extremely helpful and also helps me unmeasurably condense my reading time.

And thanks to others for the words of encouragment. It really does help when taking on something like this LOL

And on to the transmission! Hows it look?



Looks like hot spots?

This explains that damn smell!!! I though it was coming through the firewall!

Regarding the stereo wiring those wires from Boston Acoustics are for a set of component mid-high range speakers. They are crossovers, I would yank all that shit out and wire in a new set since you don't seem to have the Bostons present.

Haha cool, I'm sure others who have read this thread and got good info out of it. Are you saying I can't make the stuff thats there work? Is it worth any money?

Some more parts came!

Made a mistake though.. Accidentally got a s13 MAF instead of the s14



Bent up and diiiirty..





Straightened with the back end of a butter knife and cleaned with 409 More cleaning coming



Big thanks to FRSPORT!

You are going to need a new clutch kit and resurface the flywheel.

I'd make sure everything checks out before you do something like an autocross event. This should give you plenty of time to have everything sorted out for the beginning of the next season.

I'd throw the crossovers on Craigslist, just get a 4 channel amp and some decent 6.5inch speakers all the way around if you MUST have a system. I wouldn't even waste money on a system until the car is running though.

You can always do a system later, get that bitch on the road first!

Why do you need a system in that car? Doesn't it already have an SR with an aftermarket exhaust?

A simple radio with some normal size lightweight speakers isnt going to hurt anything. If you decide to run OEM exhaust you need something to listen to anyways.
I run the OEM exhaust, with a cut-out, that way I can hear the engine when I need/want.

Miles of unwanted cable, however, is unwanted. Every penny, toy, wire, nut, chewing gum that you find under your carpet and in the corners of the trunk you find is some 0.XXXX% of fuel economy and horsepower waiting to be unleashed.

I'm running a straight pipe LOL, and yeah, weight reduction is weight reduction My last car was a 01 Miata w/6 speed, lsd, coilovers & 8lb flywheel

So heres where I'm at.. I can't figure out how to remove that lower oil pan, am I missing something besides the bolts? my plan is to measure my bearing clearances



Is this supposed to be sealed?


Then I see this... My oil filter was still on when I flipped it but does this leak mean anything?





I got my oem exhaust manifold

Is that valve open (it looks open)? Oil is making it passed the rings. I never tested but I don't think it's that unusual if it has been sitting like that for a while. Rings do have gaps.

If the valve is closed then it's an issue.

Some progress..

gotta do what ya gotta do lol




Found some "H" metal things and ball bearings! Is this from a previously blown BB turbo? (penny is to show size lol)




Soooooo... My plan is to take a visual and measurements on at least one rod bearing. I picked up plastigauge too. Tips are welcome!

Alright

1. "Is this supposed to be sealed?"
That is an inspection plate. It just covers a tiny hole that allows you to see into the bellhousing.

2. When you turn an SR20 upside down the lifters all bleed out. So now you will have to remove the cams and lifters, and bleed the air out of them, before you re-start that engine. Never turn the motor upside down (or let the lifters sit sideways) for this reason.

3. Measuring a rod bearing is not going to tell you much, unless the whole engine needs to replaced. chances are that if the bottom end is in "trouble" then it is one bearing, often a single random rod bearing, that is in trouble. And trouble is visual, the bearing would look scored or ruined. "Plastigauge" is not a really useful tool for someone in your position. I am still in agreement that you could pull at least one bearing (either rod #1 or #4 IMO) Just to see that is looks decent. But I would put it right back to the torque you found it (FSM) without the use of plastigauge.

finally, all the gaskets you see are just silicone. I would use Toyota grey (or permatex grey) on all the oil pan / water pump gaskets. One big noob mistake is using too much; I recommend you practice on another object to see how little it really takes to seal something up. Excess gets squeezed out, and can wind up in your oil strainer (pickup). Another noob mistake is going too tight; make sure you follow FSM torque, it does not take much tightness to get a good seal and overtightning will cause leaks and in the case of your thin pan, bent mating surfaces.

Absolutely not! You need to pull the cams and bleed the lifters when you are done having it upside down.

It really is simple. You need basic tools, a timing light, and a really good torque wrench. The torque wrench is everything. You need a very sensitive, delicate instrument, not a harbor freight unit or an old one thats been sitting around. The torque spec is about 9~ ft lbs of torque for the camshaft caps. An old, or cheap torque wrench could easily be off. A half-inch drive unit is likely too insensitive, you will want a 3/8 drive high quality torque wrench.

The camshafts can break if you do not torque them properly. Note in the instructions where it says to tighten the FRONT first, you want to do this gradually (do not simply tighten the first front two caps immediately to the first torque specification. Instead, bring them down 2/10 to 4/10 at a time, such that is takes 2-4 sequences, or 60 individual events, before the bolts have fully seated and begin to show 1-2 ft lbs of torque.) Once they are all "seated" and start showing torque, keep following the same sequence and now you are using the FSM sequence numbers i.e. 3ft lbs, 6ft lbs, 8.8 ft lbs

Lining up the cams and installing the tensioner should be simple enough for you if you can count links and verify lobe positions.

The cas sensor goes in a special way that should also be straightforward for you so make sure you look at that, and know where piston #1 TDC is on the crank pulley (second mark from the left, the yellow dot usually).

And finally the timing. The sr20 is a fickle mistress when it comes to lights. Some timing lights will give you incorrect timing, and some will not work at all. When I find a light that works well, I keep it and hold on to it forever. I still have the same old unit from 10+ years ago. Anyways, once you stab the CAS and have the cams all lined up, everything is pre-oiled and the tensioner is back in, you want to set the valve cover on the motor (but do not tighten it down, just in case something is wrong and you need to go back under there) and it should start just fine, because the CAS if installed correctly will always give you a good starting timing number between 10 and 20* btdc. The final adjustment you make with the car idling. Heres where everyone has their own tricks, that is, where you get your signal. I get my signal from the center coilpack wire of coilpack #1. I simply pull back the loom a bit and strap the pickup onto it. And heres the final trick: the pickup is reversible. If your cas is somewhat center, and the timing light is showing you some inane number like 35* that doesnt make any sense, reverse the pickup (flip it upside down) and check again.

Just first want to say thanks for all your help. I've yet to take on this portion of the 'rebuild' as I'm waiting to have a few days off where I can organize my workspace and plan it out. I saw a video of a guy bleeding the lifters without changing the timing by ziptie'ing the timing change to the cam gears. It looks like a lot less work but feed back on this would be appreciated.

On another note, I've been getting parts and waiting on others but here are 2 little challenge I encountered today. Help is welcome and NEEDED

I picked up a downpipes for $30 and it will need some modification...

As you can see, the exhaust that came with the car has been chopped up except the axle back muffler and the flange is turned the wrong way. I think I will install a universal/custom short catalytic converter AND flex pipe in the gap. EDIT: I can't find super short cat and joint that would in there thats not going to cost hundreds so I'll need to find a cheaper alternative.



Hows the placement of that wideband bung? I believe its supposed to be located a foot AFTER any bends.. Is this one okay?





Yay all 3"!



CHALLENGE 2

Turns out my JDM JUICE multi-piece wheels have a leak. One rivet has a air leak. Its hard to see but there is an arrow right below the most right spoke. I've done some reading on how to reseal the one rivet but input is welcome.



It looks like Riverside, the Japanese company that makes the wheels, does not have a contact number so I'm not sure of the torque spec so I picked this up. .. It measures torque when both removing AND tightening

The exhaust should be the simplest, cheapest thing you do to your car. Ebay downpipes are something like $40 now and the test pipe part is no longer necessary on some of them. The only thing after that you need is an OEM exhaust system which can be found locally for $20 whenever I needed one. Literally should be a $70 venture max.

The wideband should be 3-5 feet from the turbo (the wideband should stay below about 1000*F), with as few joints and gaskets between itself and the engine. An exhaust leak will make the sensor read incorrectly; this is why we prefer to limit the number of gaskets (places to leak from) in front of the wideband. The turbo flange needs an OEM gasket and about 1-2 hours of work removing ancient built up carbon (pretty sure I mentioned that alrdy but...) then you use brand new OEM locking tabs followed by an OEM outlet (or other high quality outlet. Ebay brands are known to crack). And finally it is essential to connect the trans-downpipe bracket.

You don't understand... I live on a island of hawaii with a total population of 200,000. This whole island is country and theres literally no 240's for parts. Also, its common for eBay sellers to refuse shipping to hawaii for whatever reason. Being on the continental US can have major advantages, but oh well, i can't complain.

1. At $50 shipped for a oem turbo outlet, i might just wait for it to break
2. Move bung back, got it
3. Prep flanges and new gasket and hardware, check
4. Downpipes bracket, without a doubt!
