[Mk2] [Turbo] White Smoke from Turbo !?

[JLW]

yeah if its behaving ok on cruise/idle and not been boosted for a while then I guess the majority of the oil may have been burnt off.

I was gutted when I blew my Turbo ringlands... for about half a day, then I thought fook it, lets make it a strong reliable engine with the ct20, and got on the hunt for forged pistons...

Then I thought fook that too, if im having forged pistons I may as well make the most of it, bought a GTX3076r and the rest......

Forging an engine isnt really expensive if you keep what youve got and are happy with that ( turbo/injectors/ecu), its when you take advantage of the pistons that it gets expensive

That was my thought Dale, well if it is the ring lands and they need doing then
Walton @ Nispro said it would be stupid not to use ARP head bolts and then
change the big end bearings etc. The problem is this isn't going to be cheap !
I intend to stick with the CT20B for now along with the injectors etc.
And then go for a larger turbo in the future. TBH I can't be to upset, the car
has never caused me any other issues in over a years thrashing.

I guess just upping the boost was the "final straw that broke the camels back"
well anyway lets see what the compression test brings up first.

i'd take the induction kit off and see if there is a load of oil in there. It happened to my mates mr2 and oil was actually dripping out of the induction kit cone filter

The oil will then be sucked into the turbo and then flying out of the dump valve i rekon.

If you've caught in nice and early lets hope you can just fit forged 86mm pistons and you dont need to bore out the walls.

Hi Pal

Ok ill have a look at that as well, Im hoping its not bore, but I know I noticed it early so fingers crossed.

nicely done with the ML review

funnily enough i messaged him on FB asking if he wanted to do a review on mine as he hadnt done a mr2. (no reply)

guess he has done now!



hope the damage is not too bad, if there is any.

Hi Jim

funny story, its not him who maintains his FB account, Its Vil his cameraman.
Vil is safe but when he's getting 100's of messages a day, and some really stupid ones
( I'm sure you can use your imagination lol ) its difficult to weed out the good ones.

I actually ended up putting two and two together and finding out the car dealer
company ML runs and calling his mobile lol, we had talked in the past about
getting it on the channel. But decided to wait until I had it mapped with more
power.

Anyways I'm doing the Comp test tonight, so fingers crossed.

[jimGTS]

yeh makes sense, thought id msg on the off chance, as im close to london, can understand they will be overloaded these days.

good luck with it all and be sure to share the link once its posted, because im sure itll give you motivation if the car is in a bad way.

Thanks Bud, yes I'm Ashdown Forrest area to not to far from Surrey,
as soon as its posted ill put the link on my Build Thread ( members profiles )

[JLW]

Did the compression test

Cylinder four 165 psi
Cylinder three 100psi
Cylinder two 165psi
Cylinder one 160psi



The top of the 3rd piston also
Looked damaged with a bore scope
And potential damage to the cylinder.

Looks like I'm going to have to
Find a engine builder.

Chin up, it's only money

Lol , yeah. Gonna get some prices together. Nispro who mapped
It are in Oxford and I'm 2 hours away. Abbey motorsport are
Close and have worked on the car before, but are seriously expensive.
My mate who did the compression test today is knowledgable and is going
To ask his body to cost in a price.

Like Walton said, if I'm taking it apart , then forged pistons and all the rest !

Not going to be cheap !
But hey as you guys said, it would have had to happen at some point !

[2barGee]

Standard engines are getting pretty old mate so don't let it get you down too much!

I always bought pistons etc from america as it was miles cheaper but i'm not sure that's still the case with the exchange rate now............ last time i ordered i got pistons and arp head bolts delivered to my door in 3 days for $890 .....£715 now..........

So are you going the whole hog and having a big turbo/injectors/supporting mods? Just choose wisely who you get to do it! You dont want this dragging out for months on end with failed deadlines. Need any advice on specific areas of the build then let me know

[SonicSW20]

If you're going to go bigger, this would be the time to do it if you can stretch to it if it's all coming out anyway

[jimGTS]

well thats annoying!!

i wouldnt personally be going back to them if their map didnt last 5 minutes.


out of interest does the car feel any different? burning through oil?


ive had mine up at those boost levels for a long time, guess there is a bit of luck involved, but i do run water/meth injection since i bought it.
worth a thought.

[androo007]

A forged rebuild will cost you £2500 back to where you were....

To go bigger (400hp) add a other 3-4k.

£2500! Jesus man that crazy high!

Mate, sucks for you, I remember seeing your car at Japfest last year going round the track, looked and sounded spot on. keep reading about this sort of thing happening and does get me thinking when I put my foot down sometimes, when I got the car it ran 1.3, I backed that down to 1.2, and since I've taken it down to 1.1, but even so it does make me wonder when something is going to let go!

I can appreciate the opinion of wanting to have a warranty on work etc and to have a professional do the work for you, if only to save on time (potentially). But...the 3S is not a hard engine to work on, if you have a solid drive/garage doing this yourself is not as crazy as it might seem. I can appreciate its easy to get overwhelmed thinking about every little thing that could go wrong or needs to be done, but maybe make a plan of what you want the outcome to be and a list of the parts needed to do that and see if it seems too much. Whats the worst that could happen?(rhetorical! )

[Dale_V]

To get back to where you were, without upgrading.
apx.

pistons - £550
bearings - £120
gasket set - £250
water pump/cambelt kit - £200
oil pump - £100
honing - £50
oil - running in 15 litres (3 oil changes) - £50
oil - final - £45
coolant - £15
Time to get engine out - 2 hours
dismantle + assembly time inc head (valve stem seals) - 10 hours
refit - (inc running in/coolant bleeding/ fluids changing) 5 hours

DIY = £1080

DIY + if they need doing too £1380

Total inc labour if needed @ £40/hour = £2060

[yokomomr4bx]

Spot on Dale V, this is exactly what I would do. You could take a few months to spread the cost and really get to know your engine. I would note though (having tried it both ways, that the clutch is infinitely easier to replace with the engine out already!) so maybe bear that in mind in the rebuild regardless of whether you do it yourself or not.

[JLW]

Hi Guys

Thanks for all the helpful feedback, really appreciate it

I'm not too bummed out tbh, its just one of those things.
Now onto getting it rebuilt, Jim you mentioned you wouldn't take it back to Walton @ Nispro ( mapper )
But could his map really of caused this damage,
or could the 3rd cylinder have already had some deterioration that the map
and increase in power just finished off ?

Walton is well respected and I do trust him, Abbey Motorsport who are
actually a lot closer are another option, however when I was quoted by them
for installing and mapping the LINK G4 storm I have now, they were
1k more then Nispro !! And I expect they will be severely more expensive on
a full forged build.

In regards to doing this myself, thats never going to happen. I appreciate
that you guys are a fair bit more mechanically knowledgable then me and
could do yourselves, but its not something I could tackle tbh. Plus time for
me.

In regards to going bigger turbo and injectors etc right now, I'm not.
gonna stick with the OEM injectors and CT20b for the moment ( Cost )
I fully intend to go with larger Turbo in the future, but for the moment this
is a cost I wasn't anticipating. Walton mentioned it would be smart to change
the fuel pump whilst out, but that the injectors were not close to maxing out
so they could stay for the meantime.

I also agree that it would be an ideal time to change the clutch and will speak
to Walton about that, or whoever I go with, but again thats more cost.
I have about 1k spare right now for parts and get paid this Friday.
If pay check is good ( Commission basis ) then i could potentially do this straight away in one go.

Im chasing up for estimates today. Will keep you guys posted.

P.S here is the print out of the map for those interested


Thanks,

J.
