Engine rebuild parts/kits

raising the compression a bit will increase hp, its one of the biggest factors in the different gens.

 

it can be done with pistons, Id recommend a high quality head gasket to go along with it. Wait for someone who knows more to give ya soemore info

 

if you are wanting to buy a new head that is completely I No that The company that sponsers Mafix, Paradise Racing, They sell complete Cylinder heads for the 3SGE/3SGTE that are fully ported and polished and equipped with a 3 angle valve job... but they are kinda spendy. They also carry other performance stuff also for the 162/5. but more for the 165.

Here is the link so you can check the head out.

holy crap. thats a bit spendy my ass. that was as much as my celica. frak man! shoot, go get a metal gasket, arp studs, a dremmel and bore that shit out yourself. you can always find a local machine shop and ask them if they will quote you a price on it. lower end i know nothing about. might look into bigger injectors as well. unless you want batter mpg. i think ma70 supra injectors will fly. not too sure though.

 

:lmao: . Got you love the reaction . Yeah that is kinda expensive, But i guess if you have the money and you are building some type of super celica (MAFIX) :lol: , or any super toyota, then it would be worth the money.

 

super celica. that shit better wash itself. my god!

 

yeah i No tell me bout it lol....

 

for the record I dont think injector size effects MPG, I was thinkning abotu it the other day and I figured the o2 controlls the fuel mixture, so if it was adding more fuel the o2 would pick it up, and reduce the pulse time, and keep mpg the same, but under WOT I think the injection is controlled by MAPs so I dont know if that would be screwed up with new injectors

 

hum, well Im not sure of any rebuild kits, but if your going to stick with stock specs it might be best to just replace the pistion rings, all the seals, clean off all the carbon, and get the injectors cleaned and ballanced then repalce the HG with a high quality one. probably for a totoal of liek 150-250 dollars, plus time

 

We have issues over in the Uk finding decent 165 cylinder heads ( sorry slight hi-jack) to build from as a lot are cracked.

In fact that was one reason I swapped the heads over in mine, as the orginal 96k miler head had a slight crack.

New heads from Mister T are over £900 so the figure for a brand new head fully modified for me is not too bad.

Re the re build, I would also do the bearings at the same time, its not to costly but worth while.

 

when repalcign barrings, is there an issue with correct clearances around the crank? I wanted to repuild a GE one day and a friend of mine was saying getting the barrings to match the crank would be a big pain. Whats the real deal?

 

hmmm i thought that by increasing injector size the ecu would compensate for the lack of air to fuel ratio and increase it thus increasing an amount in speed of some sort. but i could be wrong. guys with supras always upgrade injectors from 5m's to the 7m's for more gain.

 

You need bigger injectors....if you have a bigger fuel pump...if you have more air going into the engine (non-stock turbo) ...etc..... isn't that just common sense?

 

sorry i fergot the pump. hahaha silly me. walboro is reccomended

 

There are numbers on the crank and block, you can go to your toyota dealer with them and they'll give you a set of bearings that is the perfect size. So not too hard, though issues arise if the crank has been damaged (like when a rod bearing has been spun), and you have to change the crank. Then there might be a issue, better ask some one with more experience in that area.

If you are rebuilding the motor, be sure to do the rod, main, and thrust bearings. It is really not worth the time doing the top end if the bottom end is not done as well. And rod bearing failure is common in the 3sge.

 

It is as much a pain as doing anything with precision on an automobile. There is a very inexpensive way to check clearances by yourself. Its a disposable tool called plasti-guage. like little strips of wax really, and the box has a guide to work off of.

assuming you have a torque wrench...
what you do:
(example: main crank bearings)
with the crankshaft in place and with bearing inserts properly placed.
tighten every cap down to torque spec. (slowly/evenly)
remove the cap from whichever bearing you want to check.
place the plasti-guage on top of the crank.
replace the cap on top of the strip, and tighten to spec.
once again remove the cap and compare the strip to the box.
the strip will be squeezed flat, and depending on how flat, you'll know the clearance value.

you can do this with all/any bearings

any comments?

 

Dman_23 is correct it's really no big deal as long as you follow the manual and don't mix up your bearing caps.


The top pic on the page shows you how to find the numbers. I can even show you how to replace those bearings without removing the crankshaft.
