Turbo'in 1.6 16V?

[coochiSR]

Anyone done one yet? and fitted it to a nova, i know Ad's has got the N/A Engine but fancied turbo'in it and fitting it in the near future. All help is helpful, thank you.

See Timmy's thread of almost same title... from this week.

[coochiSR]

Cheers CG, only just about got on, at college so doing it on the sly :D

here dude.

Cheers CG :D

So it's gonna be easier and cheaper to turbo an 8v?

Hmmmmmmmmmmmmmmmmmmm, Start saving me thinks.

[Riggy]

regal do a complete turbo kit for them , 4 grand though lol

atleast they are availiable though

[craig green]

Wheras on the 8v you can do it cheaply on the std management (upto 8psi boost), you cant really do it with the later types of management. So you'd need a crappy 5th injector etc. Still not cheap.

To do it properly, you'd be spending 2 -3 grand easy. Its all bespoke & custom parts really, like manifolds, pistons, management & mapping etc.

Do itto a 2.0 8v for best results on the cheap.

[coochiSR]

So how much would i look to spend on doing it on a 1.6 8v then?

[craig green]

No idea, depends how many strings you can pull, where the turbo comes from etc.

Have a read in projects on www.homemadeturbo.com (http://www.homemadeturbo.com)

[coochiSR]

Cheers Craig for all the help. Guessing i'll need a GSI tank, lines and loom aswell as the engine to go in the 1.2?

[Stuart]

turbo the 1.2... :D

[coochiSR]

You paying Stu?

Have a read in projects on www.homemadeturbo.com (http://www.homemadeturbo.com) Awesome site to look at that.
Shows how people adapt std exhaust manifolds etc.


Depending how much work you put in/whether you fancy getting involved with diy mapping etc, you could turbo a 1.6 16v for cheap cheap.
Adapt the std manifold, spacer plate/skim std pistons, keep the std upper inlet, cheap scrapyard turbo(T25)/boost hoses/ic.
Megasquirt, and then spend out on the mapping.

Id bet money that you could do it for ?1000-?1500.

A guy on mig has had 245bhp from a 1.6 16v ;)

[coochiSR]

Fancy doing it too Ad?

[Adam]

I want to see it done by someone.
Personally id rather be putting the cash towards "other" things not involving nova's atm.

And if i decided spend some cash id just fit a boring Let tbh lol

[coochiSR]

You gobber!
I'm liking the idea of the 1.6 8v atm, what brake they run etc? Easy to get bit's for? Pistons, ARPs?
Use a T2?

[Adam]

Wont need arp's if staying at the standard rev limit.
Could use a t2, or t25.
150hp is a easy target.

[coochiSR]

How hard is it to get hold of everything else? Will i need to get stand alone management to run a good boost?

[Adam]

Well, you can run 5-8psi on the standard management, jsut by upping the fuel with a dual rate regulator or tricking the ecu into injecting extra fuel.

The hardest thing find at the minute is a turbo exhaust manifold.

[coochiSR]

Would regulator's would i need? recirc valve? Is there an engine i can nick it all from or is 90% of it "hand" built

http://cgi.ebay.co.uk/Vauxhall-3-Bar-Fuel-preasure-Regulator-Cavalier-turbo_W0QQitemZ130175262092QQihZ003QQcategoryZ1040 4QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
Any good?

[Adam]

No, it has to be a regulator than can change its pressure when the engines on boost.

That on Ebay is just a std regulator off a xe/let engine.

[coochiSR]

O okie pokie, bit new to this atm.

[craig green]

We keep saying it but if you have to ask, you stand little chance of doing it tbh.

My advice is;

get a rebuilt engine,
put it on an engine stand,
remove cyl head & sump,
figure out & measure for manifold with the turbo you are using,
measure for turbo to oil return in sump,
plumb in oil return & feeds etc

& so on. You will need a solution for the de-compression of the cylinders. Work out what breathers need re-routing etc from booost side of throttle.

Find a viable intercooler to use. Configure it witin bumperspace etc & make up boost hoses & elbow pipes etc.

With the engine in place you will also need a custom exhaust downpipe from the turbo's wastegate to your existing system.

There is so much missing from the above, but it should begin to guide you in the right direction & the best place to start (rebuilt short motor & a stand).

By a book is my advice....

[craig green]

not the book I was thinking of but....

[coochiSR]

Where's the best place to get a new set of Forged piston's that'll drop the CR, how much will i look at paying roughly? Any other bit's i could do with to lower CR. I know there's a spacer but not 100% happy with the idea. Guessing it just run's off the standard inlet? just with inductiuon pipe's and vacuums moved?

Is it gonna be a good idea to get a T2 from Ebay and get it rebuilt?
Ad, the regulator, Guessing you can get these from anywhere? just look around for a boost adjustable pressure regulator? (Best way i could describe it)

Thanks for the book link, gonna be buying that me thinks, just for a bit more of an understanding.

[craig green]

No one I know of lists any smallblock pistons suitable to lower the C/R.

You'd have to persuade someone to run off a custom set. Group buy? :roll:

MVAUX were doing them but the site is defunct.

[Mike]

I have pretty much all the parts needed to turbo an 8v :D even a turbo manifold ;)

[Adam]

Where's the best place to get a new set of Forged piston's that'll drop the CR

Skim the standard ones down,Lol.
Or spacer plate

OR, one think i looked into is C16NZ pistons, afaik they are quite "dished" and the engine runs a lower compression than a 16se, might be worth looking at, as 16nz's are in scrapyards everywhere.

[womble sri]

velosmotorsport used to produce some silly engines but they have gone under since and i think the engines has a 10 min lifespan. they were selling a 197bhp 1.4 16v at one point
