View Full Version : My engine rebuild

05-05-2009, 11:14 PM
On saturday I went to my local pull a part and got an engine. They only had 5sfe's though and only camrys so i pulled one out of a camry and brought it home for 97 bucks. i have stripped it down and it is good!!! What are some internal things i could do to it to give it more power. I cant afford new cams so that is out of the question. What do you think about boreing it .030 over?

05-06-2009, 03:00 PM
If you can't afford a simple cam regrind, then i wouldn't mess with internals.... it'll be more expensive. Boring that motor over will necessitate new pistons, in a custom size. They aren't cheap.

05-06-2009, 03:24 PM
Port polish, im sure with a bit of research it could be done at home and get some power gain out of it. I'm sure some headers off a 4th gen 3SGE if you can find them will help too.

05-07-2009, 12:10 AM
yeah i found some headers for a 5sfe on ebay i was lookin at. I was thinking about getting the head ported and polished. the only reason i dont want do do cams is cause the cheapest set i can find is like 800 bucks. And new pistons are not near as much.

05-07-2009, 12:22 AM
All internals are going to be expensive. If you want cheap power get a k&n filter in your stock airbox, upgrade your plugs and wires, exhaust if you can afford it right now. Run 92+ octane fuel and advance your timing to 16 degrees BTDC.

05-07-2009, 12:33 AM
i already got a short ram intake, i need new wires cause mine are totalled and im getting new plugs. What exhaust do you recommend

05-07-2009, 01:07 AM
honestly man, if the bottom end is good then dont mess with it. id put a 3sgte head on it with the ct26 and a fmic. the stock 3sgte head flows really good so no need to port and polish it just clean her up real good with a can of oven cleaner and a wire brush. all the stock 3sgte stuff you can pick up pretty cheap off of www.mr2oc.com

if you over bore the motor and spend all the money to do it i just for see you saying "man that really wasnt worth it..."

05-07-2009, 01:18 AM
If the bottom end is good, id freshen it up a little bit, well the whole motor actually.

Drop it into the Vert, an build yourself a 5SFTE. You push decent numbers on an all stock 5sfe of that year. But it will indeed some love first.

Just a thought :)

05-07-2009, 01:24 AM
I thought about the 5sfte but right now im just doin small stuff to get a daily driver soon. After i get it running i am planning on saving up and getting a 3sgte and dropping it in there and calling it good.

Check out the stickies in the NA forum, most of your questions will be answered. This one in particular- http://www.celicatech.com/forums/showthread.php?t=35279

I understand.

Well I can offer some of my tips.

CAI along with other breather mods. Such as Headers/catback system.

The better your car can breathe, the more life you'll see out of it.

I guess you could advance the timing a little bit, maybe it will help put a little pep in its step.

As far as internals go, if you arnt going to drop bucks, dont do it. Cost money.

Hope i helped. Keep us posted bro

Dude. No.

91. Rev1.

05-08-2009, 02:05 AM
Thanks to all. Im gonna start by taking to the machine shop to get the cylinders measured and honed and we will go from there.

05-08-2009, 03:08 AM
Sweet mang.....lookin' foward to seeing some of your progress.

05-12-2009, 02:11 AM
well my automotive teacher at my "votech" gave me a number for a machine shop he would recommend now i need to call it. I just finished installing my clutch pedal and brake pedal for my manual swap. I ran the shift linkages and shifter assembly a few weeks ago. Now all i need is to put my tranny in. (And finish my engine)

05-21-2009, 07:01 PM
okay so the engine is out of a 92 camry my car is a 91. some of the plugs are different. So do i need a different wiring harness or just alot of cutting and splicing??

05-21-2009, 08:35 PM
What are you finding that is different? When I put a 90-91 aka rev1 engine in my 92, the only thing that was different was that the engine didn't have a knock sensor so I had an extra plug.

05-21-2009, 09:28 PM
my brother said that all of them are different but he might just be crazy i havnt had time to go look in depth but ill look today.

05-21-2009, 09:37 PM
I just did this same transplant. It's all the same.

You re-use your intake manifold w/throttlebody (TPS is different), waterneck(log), valve cover, sparkplug wires and distributor.

That's it. No cutting wires or hacking anything up.
All you leave unplugged is the wire going to the knock sensor.

okay thanks

I havn't posted on here for a while but i was workin on the engine today putting it on an engine stand and one of the bolt holes to put the tranny on cracked. Off the topic i was wondering what the best transmission is to put in. I finished the automatic to manual swap and tore apart the manual from my parts car and it is trashed. So im gonna make a junk yard run and was wonderin what the best one is?


09-20-2009, 04:06 AM
s54 from a 94+ celica

09-20-2009, 04:46 PM
will that bolt right up with out any modifications? Will i have to run different shift linkages?

09-20-2009, 04:48 PM
no modification

09-20-2009, 05:47 PM
okay cool and is that the only manuals that came in the 6g's or is there a way of indentifying it?

09-21-2009, 02:02 AM
no modification

almost no modification. You will need to transfer the manual speedo cable from your old tranny to the s54. That will be a way to tell if its the right tranny too. Hopefully it will still have the electric speedo cable attached.

09-22-2009, 11:51 PM
When i go to the Junk yard to pull a transmission is that the only manuals that came in the 6th gens

I finally had time to start back on my rebuild yesterday. I dug up the block out of my shed and threw on some red hi heat paint. The rebuild kit I'm using i got off ebay It comes with new pistons/rings, King main/rod bearings, oil pump, water pump. Full timing belt kit with tensioner and idler pulleys, And a complete gasket set. I am in the process right now of porting and polishing my head and have chrome headers to throw on once its complete. I still need to go pull a transmission which i will do when i get closer to that step.

In case any of you are wondering this is the kit i bought

hopefully these pictures work


bottom end

New pistons

This gear was on the crank cause i got it out of a camry and decided to use my old block so i just beat it off and it works good so far

02-27-2010, 04:15 AM
so i rebuilt my head today and before i put it on I'm wondering what the best way is to check if its warped? I dont think it is because it sits on a flat table without wobbling or any thing but i know it still could be. And i was also wondering how to line up the cams when i put them in.

02-28-2010, 04:56 AM
first clean the head then install the head bolts and torque them, lube the cam lobes and lifter buckets with assembly lube or lucas oil stabilizer. did you install a bolt in the exhaust cam gear? if not you have to do that first, then install the intake cam with the knock pin 80-degrees to the left of vertical, then move the intake cam so the knock pin is 10-degrees left of vertical and match up the cam timing marks on the cam gears note there are 2 sets of timing marks + 1 other on the cam gears so use the inner ones that are close together and make sure they are the same, tighten down exhaust cam caps and remove the keeper bolt in the gear and there you go. make sure that you tighten the cam caps down in the recommended order and to the right torque specs.

also note that now before you install the head on the block is a good time to do a valve adjustment and to check the cam lobe oil clearance.

and for the head use a straight edge and run it side to side and corner to corner to check for warpage.

put the head on the cams in and the valve cover and intake manifold almost done =). Anyone want pics??

03-03-2010, 03:14 AM
Pics are always welcome.

03-04-2010, 06:20 AM

03-05-2010, 01:30 PM
thanks, And I do too.

03-16-2010, 05:19 PM
so i got the engine and transmission in and started putting on vacuum lines and heater hoses and i was looking at the bgb's and my engine is different from the 1993 since its a 91. the problem is the asv i think its called it mounts on the passenger side rear of he intake manifold. my wiring harness doesnt have the same plug as a 1993. can anyone post some pictures of a 91 intake??

03-20-2010, 06:58 AM

03-21-2010, 12:51 AM
okay thanks. That looks really good. Anyways that valve thing all the way on the left was bent on my car so i chucked it not thinking anything about it and now i cannot find it. What exactly is that. Is that the oldermoder asv
