1.6 turbo question

[Rickyb]

Does anyone know of a compony the does parts for them such as turbo exhaust manafold. i have done search's before i get told. any help much appreciated. (sorry if my spelling is bad) :roll: lol

[staggy_gsi]

i thought courtenay did a kit for the 1.6 8v but maybe im wrong?!

i thought courtenay did a kit for the 1.6 8v but maybe im wrong?!

NLS now.

[Rickyb]

im sorry to be thick but whats NLS

[smcgsi16v]

No longer serviced/stocked.

[Rickyb]

so is there anywere i can buy the parts i need. :thumb:

[Mike]

^ in a nutshell....No.

Its all a case of DIY im afriad.

[Nova_Legend]

Probably best off waiting till one comes along here or eBay

Avoid Mvaux kits, have heard a few bad things about them and their site shut down anyway.

You will prob have to get your hands on another kit to copy the spacer plate but you can make the exhaust mainifold yourself. dont know how you will get
round the trick switch? the pipe work you can have made up. i know someone in the midlands who has worked on mine and is very good at this kind of stuff.

[Mike]

With regards to the exhaust manifold, you can actually use a standard cast Iron GM item ;) youll need to get fabricated an exhaust elbow peice, with a plate on one end suitable for a GM manifold, and a plate on the other, suitable for what ever turbo you use.

^ Thats how I've done/doing mine.

[Rickyb]

thanx for the advice.:thumb: ive been doin my researce and quite a few people dont like the spacer plate thay all say get low comp pistions but i cant find them. dosent the spacer plate have to be cut like a head gasket (shape).sorry if i dont make much sence.

[Mike]

^ Dude, just becuase other dont like the spacer plate setup, what does that matter? If your building something then do it your own way chap.

And yes, the spacer plate needs to be an exact replica of the headgasket

[Rickyb]

last of the nova sr's you are a quality guy and i look forword to seing you at PVS08 if your there. cheers

[craig green]

Low comp pistons are not available for a 1600 8v (or XE) off the shelf.

I asked JE to make me a set a few years ago & was told they would not be interested in helping me...

[Rickyb]

ive decided to do it with the spacer now anyway.thanx tho.:thumb:
when i saw that you had posted i thought you were gonna be having a go again. nice to find the plesant side of you.lol

[brucer]

you got any pics of your progress?? want to see all your doing so i can see what i mite let myself into next year.lol. how much is it all costing you and what parts you using?

[Rickyb]

not got any pics yet will put some up afta crimbo. theres not much progress yet as its collecting parts and geting them made up. i only decided to do the conversion a few days ago lol i will make a progress thread afta crimbo.cheers

[brucer]

ok sounds good.cant wait.

[mikec123]

I'm running a 1.6 8v T with the spacer plate and two head gasket's either side of it. Mine is an ex courtney conversion modified by Neil Robinson! Check my feature out http://www.pngclub.com/forum/viewfeaturecar.php?ref=2953. And this is Neil's http://www.pngclub.com/forum/viewfeaturecar.php?ref=769 Hope this helps keep us informed about how it goes would be nice to see another 1.6 T:)

[brucer]

thats alot of an engine spec on them. how on earth do you figure out what will and wont work??

[Mike]

last of the nova sr's you are a quality guy and i look forword to seing you at PVS08 if your there. cheers

lol er :thumb: ill be at PV08 anyway. All being well my 1600T engine should be running aswell :D

Talking about the low comp pistions, ive been after a set but had no luck. Im having to low comp my standard pistions with the spacer plate and two head gaskets because ive blown a hole in the side of four pistions in two different cases. so im just taking the cup out of top of the pistions so there flat. This is me testing the water so dont know what will happen but should run ok. Wont be doing this until end of jan as im not in the country so will keep you upto date when done.

[Adam]

Making the "indent" in the piston flat will push compression even higher!
Giving you more problems.
You want LESS material on the pistons to lower the CR.
Or do you mean your machining off the outer raised edge of the crown?

Altho it could of been Det thats killed it, caused by a lean mix or something.

[Green16v]

Yes adam i was going to lose the lip all together to lower comp. the pistions look very nice but very pricey at the same time. ive had the mixture set up twice now and it runs fine for quiet a while before something goes wrong, i'll tyr these pistions get it set up again and see how she goes. i might be selling the car straight after ive had her set up, so might not find out how the car runs.

[Adam]

Has the fueling been checked under full boost?

[nova_stee]

wondered if some one could tell me how thick the spacer plate has to be when running a t2 turbo

[Mike]

1.5mm resulting in a 8.9:1CR

Theres more to it then just putting a spacer plate in though i can assure you that now, im building a 1600T engine at present. They take some though when starting from scratch.

[Green16v]

Ive had it rolling roaded so i guess the fueling would have been checked on full boost. when the pistions go is when ive been killing it for a while i was wondering if the heat has something to do with it.

[Mike]

^ more then likely. As standard pistons were never designed to take boost or the amount of heat generated from boost lol

[craig green]

I would imagine there is another issue causing them to melt.

What boost pressure is it maxing at?

[Green16v]

The pistions arent melting its blowing a hole in the side where the rings sit, but not causing any damage to the cylinder bore strange!!!! It will run 20psi max and im running it at about 16psi at the mo. i agree about the standard pistions were not ment to take this but im not planing on folking out for some one off pistions

[craig green]

It has to be fuelling. Unless you are on mapped standalone management.

The Bosch is only good for 12psi max I've been told.

[Adam]

20psi on standard management is pushing it a bit far imo!

[Mike]

^ 20psi with standard non turbo piston's is also pushing it a bit far IMO

[Dar]

It sounds like detonation to me. My dad did the exact same thing to his car when he ran 95ron fuel instead of 98ron.
I would deffo build a bit more of a safety margin in to your engine:thumb:

[Adam]

Green-What fuel pressure and injectors do you have?

[Green16v]

standard injectors running fse boost valve cnat remember what pressure its been a while since ive seen the car.

[Stuart]

ewwwww FSE = poo. get a weber FPR (like that fitted to a 2WD cossie)

[Adam]

Indeed/\
FSE's are crap, and just send the fuel pressure all over the place.

It might be the standard injector rates being at full duty cycle causing the problems, hence why it does it when giving it the boot.
