So recently Ive picked up a fairly damaged s13 for a project car, mechanicly the car seems fine but the panels on the car are wrecked and I have almost finished the process of replacing the wrecked panels and will be giving the car a respray. My goal is to use the car as a daily driver (so i ca garage my 34 to drive on sundays), but also use as a sleeper. Of course Im going to be doing an engine conversion but to decide the type of engine im going to put in the car is seeming to be almost to difficult for me. So here are a few ideas that have come to mind, and please take note that the car needs to be automatic.

1jz

2jz

rb25

1uz

rb20

these are jsut a few engines ive had in mind. currently im leaning towrds the 1uz as its something a bit different, 1uz s13's are rarely put together, and the engines are strong and i can lean towards either turbo or supercharge.

1jz,would be the obvious way to go as th engines are quite strong and standard internals can handle quite a bit of power as im looking at keeping the engine relatively standard and not opening it up, im aiming more towards an affective power to weight ratio and the 1jz are quite light in comparison to an rb25.

R25 would be a more straight forward instalation, I have more experiance with the rb25, I have parts lying around that would make good upgrades for the engine but with the engine being a bit heavier than the others Im concerned about the weight distrabution and would prefer not to hafto do too much to the firewall to even up the weight.

2jz, from what I understand these are a difficult engine to put into the silvia, the sump is a problem so you need to find a 2j from an aristo for a good match and i dont know of any conversion kits made for the 2j and s13 body.

rb20, tough as guts but lots of potential but will require alot more money put into it to get it making the power im looking for. Positives are this conversions been done a million times before into s13's and parts are redily available.

So just wondering what everyone elses opinions are and/or ideas.

ur budget will also contribute alot to the project as well

the engines that u have stated veray greatly in price

1uz $1700

rb20 $1000

rb25 $2000

1jz $2000

2jz $4000

the toyota prices are fairly accurate as i was recently looking for a conversion for ly ls400 and these are the prices i got.

ill be honest with u, u wont be able to do much for less than around 10 grand. half of the motors need some serious custom shit to make them fit in + the wiring will be a nightmare and add huge costs to it also.

if i were u i would put an s15 motor and s14 gearbox and it would hammer hard as

but if u have the funds then definatelty go the 1uz. that would be sick

a v8 silvia lol

oh its a project that will happen over time and i have more than enough funds to support it. Mostly I want to do the majority of the work myself for the satisfaction. Added bonuses of the 1uz are the weight in comparison to the rest of the engine I have stated, there alot lighter suprisingly. And seem to be a very nice fit into s13 enginebay, there cheap as you stated above. Supercharge maybe with ITB's i dunno.

What do you have in mind as the purpose for the car? If it involves track work then any of the engines proposed will make the car handle worse than it does stock.. If you just want a toy that is fun and a bit different then go for which ever you like/have the budget to support.

deffinetly not a track car, or else id look at an sr20. Mostly as a daily driver and for a bit of fun/project. Mostly as its something to work on myself and get some self satisfaction out of besides the few ovbious bits and pieces like wiring etc. What I will do once I get the rest of the panels and start sanding/prepping the car for spray is start a post up on progress.

Since it's going to be a daily you would want to probably look at making it legal. Engineering might be something else you're going to need to factor into the cars cost and could persuade motor choice.

I would go RB20DET or RB25DET.

I have a feeling it would be an easier conversion then fitting the Toyota engines in...

I would go RB25DET if I was doing this project.

A well balanced inline 6 with a nice over power range.

For ease of conversion and lower costs with still enough power on tap, RB25 with RB30 bottom and a GT30R off the side.

If budget isnt really too much of a conern, 2JZ with a T04Z. Stock internals you'll be up in the 400rwkw's with ease

budget isnt really a concern. As I said the downside to rb25's is the weight of the engines. I still want to retain some form of handling and they are by far the heavier engine of the lot and will require internal work to be done sooner if i end up chaseing more power. As a 1j or 2j may be more costly to install, they have alot more room for power without cracking open the engine.

Well if budget isnt a concern, the BEST would be the 2JZ. Ive got a supra with a 2JZ, awesome motor, the motors are a lot cheaper than people think if you look around. Throw either a 35R or a TO4Z on there and the widest/most grippy tyres you can afford. Heaps of fun!

Do you really think adding 2 more cylinders will turn the car into an understeering shitbox pig?

Ive been in a few 6cyl S chassis's now and they're not utterly shit as most internet mechanics would have you believe. Of course its not as ideal as a 4cyl, but if weight is that important, change the front panels for alloy/fibreglass.

Worst case, you get the suspension setup to suit. Depending on what those specs are your tyre life could suffer.

If it's going to be your daily do you really want a 400rwkw 2jz monster?

lol, yes!

I plan on doing this soon, have started getting bits together, for the ease of installation the bottom end will be RB30 or RB26. About 350rwkw, GT35R, etc. Daily driven of course :)

    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
