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

[Dale_V]

There is a chance that it was to do with the map, but it's very very unlikely seeing as the 3sgte likes to eat pistons on a standard Toyota ecu with increased boost. By having it mapped on stock pistons all you have done is accelerated the time it's took for the pistons to xxxx themselves.

If the 3sgte pistons were renowned for being strong with increased boost and mapping, and they went pop, then that would be a different story and you could blame the map. But they're not so you can't

If you trust that guy then go back to him.

It's a well known weak point on the stock 3SGTE, you have to bear in mind the engine was 20 years old and most likely unopened.

Do you have an AFR gauge in the car or any data logging with the Link? That could confirm bad luck or if there was another issue.

Dont have an AFR gauge, and I'm not sure the "Storm" does data logging,
think its just the "Fury" but I might be wrong.

[SonicSW20]

Fair. If it was otherwise running well it was most likely bad luck unfortunately - could have gone at any point!

[JLW]

Just got of the phone with Scott at Abbey Motorsport,
turns out that he would be potentially willing to match or get close to an
estimate that Walton @ Nispro fires over.

They are much closer to me and would be a lot easier with that instance,
guess its in the hands of Nispro now and how much Walton estimates the work
to cost. Im happy with either for workmanship. But Abbey being 10 miles
from home opposed to 2 hours drive could be the factor.

[Odin_S]

I had reservations when you changed your ECU to Link, now i have reservations with you using Abbey Motorsport.

They are a Nissan specialists, how many MR2s have they done before? If i had a 350Z or R35 I'd be there like a shot but not to rebuild a SW20

I know an engine is just and engine but there are I'm sure unique tolerances between engines. Else there wouldn't be specialists. Also i know travel is a factor

[jimGTS]

personally id give one of the mr2 specialists the money over one of the more random tuning garages.

with the latter i would want to know about all the mr2s theyve built and if still going strong, with an mr2 specialist or affiliate on here, you can at least contact owners about their experiences.


thats just me though.

[androo007]

+1 on a specialist.

I had a friend who abbey installed decats etc to his 350z. One decat / sports cat thing was a dud.... and they tuned it like it -one bank very lean. Didn't end well. I'd go there to use their dyno, but wouldn't hand my cash over.

There's a few super duper specialists all well within your remit pal, just get it towed there.

Ps - labour at 40 quid?! Are we in the 90's again? !

[Dale_V]

Ps - labour at 40 quid?! Are we in the 90's again? !

No. I know plenty of independants and specialists at £40 or less. They offer no bullsh/t excuses either unlike some of the affiliates on here.

[JLW]

So which are the "Specalist's" that people would recommend ?
I know SBits is one, and assuming Fensport is the other ?

[Odin_S]

Drift Limits but I'd only have Luke build it and your other is Rogue Motorsport

Lots of people are giving you info here dude, but it should be down to you to research them and see which suits you and your pocket.

Must be a suffern' tax thing then

[JLW]

I guess everyone will always champion someone they have had good experiences with, and Vice Versa. I've used Abbey Motorsport in the past
A few times, admitedly not for something this big, but I've never been
Disappointed. The same goes for Nispro, I believe Walton did a good job.
Although I'm a little disappointed the engine didn't hold for long at all,
But as said, it's potentially luck of the draw.

Personally I have had small issues with SBits and Pacific works.
Nothing to major to grumble over but that's my experience. I'll give
Rouge and Fensport a chance to through over estimates also. Can't hurt
To have more options !

[Odin_S]

I hear you

In my opinion its not just luck of the draw if the piston ring crap themselves. The percentage of 3SGTE that eat piston rings on standard pistons is higher when the car is running a standalone ecu than OEM,

The safety buffer is made less when seeking more HP on standard pistons without something like water injection to help against detonation

Although some say crude, if you're staying at around 300bhp OEM ecu is the best

[Race Idiot]

The OEM ecu is hardly crude though, the guy who was trying to make it mapable a while back dug into it's impressive featureset. It's just a shame nothing came out of it.

[JLW]

One other thing that is actually a plus point for Nispro is the fact that Walton
himself has a personally built 360bhp forged Rev 2 that he built for drifting as
a challenge !



That surely shows that he knows the engine well ?

[SonicSW20]

The OEM ecu is hardly crude though, the guy who was trying to make it mapable a while back dug into it's impressive featureset. It's just a shame nothing came out of it.

It's all relative. It's pretty stone age compared to even a modest standalone ECU these days. It's space-age compared to the Rover V8 'flapper' EFI!

[JLW]

Just had a good conversation with Matt @ Rogue Motorsport, being a specialist
as you guys mentioned it was evident in the questions he was asking that
others haven't. He's compiling an estimate for me tomorrow so at least I
have a specialist's view of completing the task.

Fensport couldn't start till late April , so thats a no for me.

[Dale_V]

JLW, it might be nice to have an 'mr2 specialist' do the work, but its far from the end of the world if you dont and just have a competent trustworthy mechanic. The 3SGTE is very very simple in design and as long as whoever builds it, follows the specifications (found in the BGB) for various things (tolerances, torque, gaps) then all is good.

Ive seen so called specialists turn out GREAT work, i've also seen them turn out rubbish, the same with non specialists.

[SonicSW20]

Indeed, I was just saying the same to JLW on Whatsapp. It's just a machine, not all *that* different to another i4 turbo of a similar vintage. One advantage of a specialist over an equally competent engine builder is the specialist will probably be able to complete the same work in less time, and therefore less labour hours charged.
