evo 3 to overhaul or not

[pac_jb]

Hi guys,

I'm wondering whether my car to be overhauled or not. The milleage is around 250000km. There's no anykind of white smoke , but the problem is now after a hard drive or long drive the engine seems to be rough and noisy abit, and now I'm thinking maybe it needs an overhaul since the engine is nearly 20years , pls advise on this guys, is it worth it or spend the money somewhere else

I am old school, not broken don't do anything, since no white smoke also....

if it aint broke, dont fix it....

 

[Izso]

I'm new school.

It's 20 years old, it's running rough and parts are pretty much wear and tear. I say if you have the money - change out all the oil seals, gaskets and do a top overhaul or if you can afford it full overhaul. But get a reliable mech la.

just use better oil quality....

bro Izso, any ballpark figure if doing full oberhaul? if not expensive, can include stroker kit...

Any rough estimation of top overhaul and full overhaul cost.

better dont play with fire..
later more money spend than budget since didnt touch no problem, once touch problem come one after another...

Exactly, once open, see this worn, that worn, might as well do all, then big bill. But as bro. Izso mentioned if got the budget go ahead and overhaul....

 

[ken yeang]

TS, do you have budget?

TS, do you have budget?

Around rm3k

keep the money then when the time comes, rebuild your engine.
u can start buying the parts bit by bit 1st.

Buy parts bit by bit, then later on change plans then rugi.....

3K probably not enough to do a full overhaul for an Evo engine. Actually I don't think it's enough to do a top overhaul either.

So we're back to square one - like what taikor vr2turbo said - since it ain't broken don't fix it cuz you don't have the budget. But if you do best to overhaul it. Having said that my friends Vios has done 300k km with only normal engine oil changes and changing of usual wear and tear stuff without ever having done an overhaul. All depends on how you drive and take care of your car.

A 4G15 Wira to do a proper full overhaul costs about 5k. I'd imagine a DOHC 4G63T would cost more than that.

 

[vr2turbo]

Should be much more since parts are more expensive. If not half cut, but engine condition is s gamble.....

my overhaul cost me this on 4g93 na..
this is workshop bill only not include part that i buy my self..
so plan wise before you do major work to ur engine..

 

[^pomen_GTR^]

if do overhaul....

ill probably do a checklist like this:

1-forged conrod
2-forged piston
3-acl/king race bearing with +1 size than original (to compensate crank and/or conrod bearing wear/machining repair)
4-metal head gasket
5-new oilpump kit
6-timingbelt kit
7-oilseal kit
8-waterpump
9-pretty much all new silicon hose
10-get spare turbo (probably rebuild with billet compressor wheel along the way)
11-emanage to tune to new engine power potential
12-new fuel pump
13-new fuel regulator (adjustable preferred)
14-all new mounting
15-spare driveshaft
16-spare 3k for gearbox rebuild (usually tendang-gear simptom happens on high mileage mitsubishi) caused by worn synchro

thats it...

eeekkkkkk....


waittt..... why in the recipt lists item most of them twice?


#ubahsuai liner- rm700 ok
#grindvalve using machine- rm304 ok
#potong crankshaft- rm220 ok
#skim head- rm80 ok
#then again skim head- rm40???
#water test head+block costs rm200???
#change valve guide- rm256 ok


all the above machine shop charged already...then why below the bill still add another RM400 for the job paid above?

 

[ken yeang]

dont forget to add......

ARP bolts/fasterner set, and the cost of engine fluids for flushing/break-in and the subsequent engine fluids, bushes, and some rubber boots (if the ori ones oredi koyak)

Well when I did a full engine overhaul on my ex-vr4 about 2 yrs ago it cost me nearly 8k �� so I assume it wld cost around that much for n evo3 since it's more or less similar engine...pls take note that all parts replaced was original parts NOT forged or race items...so if u opt for those then d cost wld probably double or more...

could not remember correctly but the skim head rm40 one is for upah cos pomen send the head by himself..
the 400 one the charge for piston job & i dont remember exactly what & few time eng. shop visit..the overhaul take month to complete due to my budget prob & me searching for the right piston..so the receipt also like what the pomen remember only..hahaha..if in detail i think the cost is higher..
