Rebuilding My 5sfe (Pics) - Toyota Nation Forum : Toyota Car and Truck Forums

So I have been talking about this lately and Saturday I really started getting my hands dirty....pun intended.....

.....I took the head off and i am going to send it to get ported and polished. I am wondering why the insides look so bad....I know a lot of carbon build up.....Do you guys think this is worth rebuilding/ with new internals or should I just gasket it/clean it and bolt it back up?

TIA for the input.

I would definitely at least put new rings on it and clean it up. But since you need to take the pistons out, might as well bore and hone that bitch!

jtex2717 · 08-31-2010, 12:36 PM

Now if I were to bore it out....how much more? I did see a larger piston for the engine.....

Its up to you if you want to spend money on new pistons. I would send them out to get check and cleaned. Also send block to machine shop and see if it can be honed if not than you can get bigger pistons. Are you doing anything special with this motor like nitrous or turbo? If so than go with new pistons/rods. If not save your money. You can always get the orginal pistons and rods cyro treated. Just my 2 cents.

Port and polish is a complete waste of money FYI.
I am selling larger forged pistons too if you need...

jtex2717 · 08-31-2010, 01:31 PM

I am thinking about Turboing.....but idk yet....I really want a 3sgte but for now I have my 5s.....I think I want to build it so that if I wanted to do a turbo build I wouldnt have to open it back up. I do however plan on getting the Cams for it. But as of right now, I just want to get all the power back and possibly more, clean it up, and make sure I dont have to keep replacing shit.....

Y is that?

To my knowledge once you port a head you actually match the intake manifold to the intake ports or vise versa and this allows for more air and likewise on the exhaust side which allots more air to exit....and polish gets everything running more smooth.....I would think this would be good for synthetic oil.....

^ +1. Why is a port and polish worthless? Just for the 5s-fe or all engines?

RichieRichJP · 08-31-2010, 04:29 PM

Because the gains are minimal.
Meisner had it done and so did CreepyEye? and had practically no gains.
I can't remember the name of the garage, something logic, but they specialize in builds that have different "stages" in polishing. In an essence, it's more of a "I'll charge you $80/hr for labor where I pocket all of the money and you paid a shitload for almost nothing" kind of deal.
I've spoken to a couple garages about this and they had dyno'd for before/after results to prove it..

And you know what, if you don't want to take my advice (since I'm apparently wrong in every topic I jump into nowadays), I'll say go ahead and get it done. Once you get it done, tell me what difference you achieved in performance.

Jeez man. I was just curious to hear your take on P&Ping.

RichieRichJP · 08-31-2010, 06:18 PM

I wasn't trying to sound like I was attacking you.
All I'm saying is since I'm always wrong based on assumptions, then prove me wrong by doing it.

mr.nitro · 08-31-2010, 08:49 PM

id clean it up and replace the gaskett. I wouldn't do any more to it.

I was in that situation once and I kept adding more and more, bore the cylinders, stroked it with a larger crank (im talking a chevy engine) adding allum roler lifters, street/strip cam,new intake etc. bottom line is it became a money pit. I regretted doing it and should have just fixed the problem. it came out great, but it set me back a lot of money.

***LynchburgCSI*** · 08-31-2010, 09:07 PM

By the way... just rebuilding right? No plans to go turbo or anything? If you wanted to do an FI setup, i'd DEFINITELY do the rings as well as all the gaskets.

Eh. Well, It might be worth my time if I were to do it myself. Nice little weekend project.

***Gothmog3VZ*** · 08-31-2010, 09:56 PM

In this case, I'd agree with richie somewhat

P&P will give pretty much minimal benefits, especially on a N/A - might be better to swap 3s-ge heads (if that's doable). Because, frankly, on a smaller engine, the only time you might notice the effects of a P&P would be at higher RPMs, or with FI - otherwise, it's up to you whether you want to do it.

I might do my intake manifold, but only because I got a lot of spare time on my hands

Thanks for the input Richie.....Nothing is definite right now so I value anything that is suggested. If I am going to waste my time and money on a P&P then I am not going to do it. I do however need to send it out to get cleaned. We dont have any type of cleaning machine at my shop so everything needs to be outsourced. I am however looking into turboing the car but I ultimately just might get it to run well, look clean and drop it in until I can get my hands on either a 3sgte or an MR2....But i still do want to have some cams done
