[/B]i have a my95 wrx import. i only had it 2 weeks and i was on motorway and engine went bang!!!!! a con rod came through the block i over revd it i thought of it being a import it would have a rev limiter on it???!!!

got a engine from ebay for £500. and just got car back last friday.

any 1 done the same??? engine switch i mean??
need advice? the does and dont after a engine switch. and at what revs is it safe to drive on??? as im scared the same will happen again. run out of pocket money and mam and dad wont give me a increase lol! help would be appreciated cheers

You over revved it ?

How, 3rd gear, you went to 6k or something ?

yet u say motorway,5th gear im presuming,how can it be over revved ?

de-retricted ?

anyhoo, if the engine is of a healthy state,there shouldnt really be a running in period as its just an engine from another car,put decent oil in, be kind to it etc.

i thought they all had limiters even in fith gear!

the limiter isn't gear related. it's just a rev limiter, you'll hit it no matter what gear you're in. normally around 7k for normal WRXs

Will

yes sorry de-restricted. mechanic said i was going 2 fast you over revd it he said. people said to me that you can red line a scooby at every gear if you want cauz the engines are so strong?? is that a lie?? what is the safest rpm to change gear when you are booting it??

Will

by the way i was doing about 140 mph in 5th

Same sortof thing happened to me in my classic 93 import,after only 2 weeks of getting it the engine went pop,fooked crankshaft and pistons!!
New crankshaft £400 plus an engine rebuild another £1500!!
Didn't trust getting a second hand engine,now I have to keep it at 3000revs or less for the first 1000miles,to let it run in.
Good luck with yours anyway m8

gaz-cole

sorry mate you know how it is sunday afternoon just back from the local, what i meant was its there in every gear as its ecu controlled but ive still never hit in fith at even well past 150 on a private road of course

yeah, i thought the gearing would stop the rev limiter being hit in 5th gear ?

140 mph isnt redline revs tho is it ?!?!?!

This is why,when i get mine de-restircted, i will break her in slowly,its done max of 112 all its life,dont want to go straight to 140-150 if it will straight away,ease her in,120,130,140 after a few weeks like......

gaz-cole

150mph isnt far off apparently there is a progressive limter on these i remember scott.t saying hes the best for info on early ecu,s i think

Will

no no at the time on the motorway i wasent on the red line think bout 6k rpm. with the second hand engine do you think its safe to drive fast or break her in slowly, u know bout 4000rpm for 500 miles. at each gear change what rpm do you recommend i go up to before changeing??? or whats the maximum?? im scared of going over 80mph at the mo incase another con rod popps through to say helo

gaz-cole

in all honesty mate if was a bad lump you would know about it,(gone bang by now) do a couple of oil changes to make sure its got proper fresh good oil in it put some good plugs and a filter and if not already do the timing belt and should be ok, its not all bad news with second hand lumps

Will

cheers gaz. yes i made sure the mechanic gave it a full service whilst puting it in, filters,belts, plugs the lot. but for some reason?? the mechanic put semi-synthetic in!! is it true you should do a oil change every 3 months or so??? did i mention i got a my95 and the lump i got was 94..... is there any diffrence?? performance wise. sorry for all the questions. its my first scooby and havent got a clue. and appreciate all the advice

gaz-cole

i use semi in mine and change it 3 months because i get it trade and its good practice if its got the specific rating it will be fine for it mate

blueangel

If its a second hand lump it should be ok,provided it was running ok before it was removed,but you'll just have to take that chance,unlike mine which has had new crankshaft, pistons, mainbearing,conrods etc,which has to be run in gently.
If it was going to pop it most probably would have by now.

Will

how though?? if i havent gone more than 80mph

blueangel

Did you check the donor engine out,before it was dropped into your car??

wrxmania

Jap cars are not mapped for beyond 112 MPH that is why they should stay limited in this country until they are mapped properly. No wonder it went bang - I assume you are using V-Power with Octane booster and not just standard unleaded.

Um,didnt really think they had to be "mapped" to run beyond 112 mph, as long as ur using high ron fuel /healthy engine the speed you do didnt matter ?!?!?!?

hmmmm............

wrxmania

Well, the ECU won't know how to manage the fuelling etc, so with the high temperatures under the bonnet, fuelling which is a guessing game etc, it is a real risk to run an unmapped car above 112MPH.

Will

yes i did check the other engine, it was very clean and looks healthy. i was useing super unleded. where can i go and get my car mapped then?????
