JLW's ( REV 3 GT spec Turbo, smg Tbar ) YVS Performance Built

[JLW]

So, Simons been on the case already and has been incredibly helpful, glad
I've gone with him. He sent me these photos earlier.
As you can see the pistons and head have a fair amount of damage to them.
He said this is all caused due to DET and most likely from the map, the only
Other thing that could cause it is any drastic changes since the map, which
Hasn't happened !









One other thing is the damaged ringlands , Simon actually said that this was a
Blessing in disguise as it's showed my engine was DETing once it's been
Stripped and investigated, otherwise I would have kept on driving until
It really went bang !

So we just had a large discussion over the phone to decide the shopping list,
He's again asked me my plans for power. I never anticipate going over 500bhp
And therefore it has given Simon the idea that there are things I don't need.

One good thing is that the bores seem to be really good and therefore don't
Need any work, so we will use 86mm Forged CP Pistons. However it needs
A new clutch, so we will go updated and most probably a Helix clutch
As that's what Simon prefers. He said the engines in great condition apart
From the DET damage, and even said if I wanted I could leave the bearings
That the engine has in there as they are in good condition. But advised to
Change which I also agree with. Finally , the engine radiator has seen better
Days, so a Mishimoto rad will be bought and we can remove the AC system
At the same time.

The list should be something like the below.

CP 86mm Forged Pistons
Toyota water pump
Toyota gasket kit ( HKS if going over 600bhp )
ARP head stud conversion
Toyota oil pump
Helix clutch
ACL race bearings ( crank and big end I believe )
Mishimoto Rad

I'm sure there are parts I have forgotten , but that's the plan for now.

Not tempted with a 5S mate?

So waltons map wasnt good then? Mmmm... maybe avoiding him in future if thats the case.

[Dale_V]

Lol rogue would still be winding up his ramps milking that £62.50 + vat hourly rate

It's also good to see a garage that actually pull their finger out of their ar$e

[jimGTS]

Isnt that damage not the missing bits of the plug hitting the head and piston?

[2barGee]

Wow impressive cracked ringlands there mate, good work.

See how quick Si works, this is why i always go back to him

[Dale_V]

I used YVS about 12 years ago.. before I knew nothing about engines! He was great and found my engine issue in less than an hour, to which other affiliates on here failed to find after having the car days

Popped in to see simon last year for some advice as I just worked around the corner from his unit... he knows his onions!

[JLW]

Not tempted with a 5S mate?

Nah considering Simon has said the engine's in good condition aside from the
DET damage, I'm going to work with this. Also saves spending more money.

He did mention that the plug end wouldn't actually cause that much damage,
However the plug that broke was in cylinder 1 and as you can see from the picture, that looks more like 2 or 3.

Those det marks on the head look surprisingly deep- are they gonna come clean without taking too much material off? Sounds like this could be a quick turnaround, but you should stick some rods in cos you will end up chasing power further down the line...we all do!!

[androo007]

I'm testimonial to that for one

That's biiig det....would be interested in seeing your map compared to others (I'm no expert but interested regardless).

Flamin heck he doesn't hang around does he?

[androo007]

Additionally, have you looked into adding on the knock block? I'm tempted.

[Odin_S]

Not wanting to say i told you so, but i did say before you put the Link ECU. The only time you need to change the OEM ecu is when you change the turbo and fueling

OEM is easily best for the setup you had, no such thing in my opinion as free HP. Fuel cut at 1.2bar is there for a reason

Which pistons are you going for? compression ratio i mean?

Nothing wrong with stock fuelling/turbo and an aftermarket ecu.

In fact, it's better as you can map it to 1.2 bar, where as the stock one, you can't.

Having said that, I have Wossner forged pistons in mine.

A standalone ecu can also be mapped for performance, whereas there is a degree of economy mapped into the stock ecu, which obviously can't be re-mapped.

[androo007]

I think the one thing I'm surprised at is that it's kinda law; hit 1.2 bar on a stock block and you have a ticking timebomb. Even more so if the tuner is naff on a standalone.

I have not seen 1 person that's said "I've been running 1.2 bar for 40,000 miles and had 0 problems". EVERYONE blows a ringland.

Anyway.... it's just a good excuse to make it go faster

[Odin_S]

I could say that.... i got my car in '08 at 88'000km ran prefectly all the way up to '14 125'000km when i wanted more power.

Usual bolt ons and boost upto 1.2bar. I could be lucky but i doubt it.
I said upto 1.2bar but i rarely went up to that. Don't wanna sound like a smart ass but i always had my own limiter in my brain that eased off for fear of detonation

I just set my boost to 1.1bar then trimmed the duty.

I'm sure there are plenty others.

Now with low compression pistons and WI I've done all i can to protect against detonation so i can relax a little

He actually dropped off the head at the machining shop yesterday, and hasn't
said that its needing anything else other than that. In regards to rod's this
is something I'm hearing from a lot of people, I'm definitely going to be
upping the power later this year with Turbo etc, however I don't see myself
going over 500bhp and Simon categorically stated the car won't need rods
unless I do. Im just going to go wth his expertise as it will be on his head if it
does let go due to rods lol.

That's biiig det....would be interested in seeing your map compared to others (I'm no expert but interested regardless).

Flamin heck he doesn't hang around does he?

No he’s working very quickly which is great, but I do have to spread this over the next pay check
Also lol.

The problem is that I'm new to all this, it was always sports bikes and
supermoto's before, Fensport and Abbey Motorsport both quoted me for
fitting standalone ECU's with stock turbo, It was only my choice to choose
Nispro as Walton was selling his LINK G4 Storm cheap and offered to fit and
map for a very good price !

I dont personally think it was the LINK being fitted that was the problem but
the quality of the map itself, Simon at YVS has said that its been "DETTing its
titts off". Anyway its an expense that I wasn't expecting, however one I
was bound to do anyways. Its nice knowing that the engines going to be in tip
top shape to build power onto.

how about over 100 1/4 passes in 3/4years?

[JLW]

Who did your Map JIM ?

[jimGTS]

I've been on oem and blitz ecu all that time.
Fine tuned with a fuel pressure reg and a safc2 (map sensor controller), just tweaked by me on the road.

Oh I see, so they are like a halfway step between OEM and a full standalone ?
