Just bolting one on to the Engine in standard form? I would expect it to hit boost then destroy itself with too much compression

There have however been a few proper 1.4 Turbo conversions, have a search on here for some info on them!

 

I dont understand why people say its so expensive to turbo the k series, surely if you can do the work yourself it isnt too bad?

By the way forrest, hows the 200? did you get it sorted in the end?

 

IF you can do EVERYTHING then, its it wont be as much as usual.

But that's not a lot of people now is it haha

There is a lot more to it than just bolting a turbo to it, as mentioned above, the compression needs to be reduced for turbo's etc

Plus any internal work, which im pretty sure a K-series would need to be turbo'd!

 

it could be done, but like everyone says if it was literally just bolted on then i doubt it owuld have lasted unless it was running next to no boost. i turbo converted my 2.0 8v corsa, done all the work myself, cost around £400 to do, out of curiosity what size are pistons in these 1.4s?

 

The Vauxhall engines are easier to turbo down to the fact all the older generation Engines have fully interchangeable components, the people running the 1.3 smallblock turbo's use the heads from the 1.6 Engine to lower the compression, and the internals are generally cheaper (well from my experience of them).

With the K the easiest way to lower the Compression ready for a turbo you would need to have a custom made decompression plate made (as far as I'm aware they aren't available off the shelf). Also noting standard 1.4 Pistons are only suitable for up to 160bhp (according to Dave Andrews) which is 55 bhp over standard so they would need replacing also - as well as the other components.

It's easy enough in theory to do, just requires the Engine rebuilding from the ground up, then mapping to suit.

 

no most the vaux 8vs runn near enough the same compression ratio as the cav/calibra turbos so u can put 1 bar of boost through it on standard internals, but i was running 22psi so used cossie pistons rather than a de-compression plate, basically the lower the compression them more boost u can run to a certain extent, but then u have the fuelling side needing bigger injectors possible fuel pump, rising FPR then a decent remap, i had mine done on megasquirt, gave me 293bhp from a 115bhp engine

 

Why do you have to lower the compression? (I am not questioning/doubting you, I am just asking out of interest).

I'm not a gasser person but my two cents would be that it would be to avoid detonation (premature combustion) due to the high pressures encountered when the cylinders are being charged with air rather than taking it in at ambient pressure.

Other changes might (emphasise 'might') apply too - petrol engines need to meter both air and fuel delivery to get the correct a/f ratio - turbocharged engines naturally process more air so will naturally process more fuel too for the extra power - so it's likely the injectors might be different, and perhaps even the ecu too - you might get one with firmware engineered for dealing with air pressures much above atmospheric etc.

Just a couple of reasons.

 

Theres so many can I turbo this can I turbo that threads its quite amusing .,...... No effence op

 

Trust me im not rich enough to put a turbo in a 1.4.
Im putting a 1.6 in my 200 next year when funds allow. Till then i'll just have to plod a long in my modded 25 td.

Tbf i've got all the power i'll ever need in my 25 atm. I used it the other day to move my siezed up 200, i didnt even need to push the throttle, diesel creep moved it enough for that.

I've been told that it was possable by a work collegue. I didnt belive him. Now im going to ask him all sorts of question about how he didnt blow it up
I think he's telling fibs.

It is indeed possible and reading around a few of them exist at the moment. I'll be turboing my VVC with low boost once I've finished gathering the parts and then building up a forged engine to up the boost :broon:

 

what would happen if you put a turbo on a 1.4?

.....Bang!

 

one thing I've always wondered is why couldn't you start with a stock 1.8 turbo k series from another rover (75 I belive?) and then uprate the engine to handle higher boost or bigger turbo...

is it doable? or is the engine too large to fit, too unreliable etc etc.

 

The 1.8k turbo has slightly stronger pistons (same as the Mexican VVC I believe) and different rods to lower the compression. As you would change these components anyway you could start with any block.

 

The 75 engine is the same basic layout. In theory you can drop the engine straight in (changing a couple of sensors) then just get the ECU remapped and you're looking at 180bhp from out the box.

 

I see... so am I being silly for asking why we dont see a lot of people doing this instead of going for the T series?

What power do you reckon you can get from the 75 engine without having to swap out any internals... I mean as a "cheapish" upgrade you don't need huge power that I know you CAN get from a turbo, but 50+ extra bhp would surely be enough for a few of us with the non-vvc 1.8, and especially a 1.4 :lol:?

I'd think it works out much cheaper to get one and play about with that and get 200bhp+ from it than it would to turbo a 1.4 or a standard 1.8 ?

 

From the research i've done, you can remap a standard 75/ZT to 187bhp. The engine is good for 200bhp on standard internals.

The problem is, getting a 1.8T engine is about £700-£850. Its actually cheaper to buy the complete car and strip it yourself.

 

Forgot to mention that if you decide the 1.8T route, the more power you want from it, the more you have to upgrade. If you want anything above 200bhp you'd need to think about changing the fuel pump as well.

 

Okidoke then, looks like I've found myself a project :lol:... and to think there was a 75 1.8 turbo in my scrappy the other day :facepalm:

Now I just need to learn how to remove an engine... I should really take a course in vehicle mechanics or something shouldn't I?

So the cheapest/easiest way to get a turbo k series is to get a 1.8l turbo 75 engine/car and play with it.

With forged internals and a bigger turbo and FMIC what cost/power can you expect to have?

Basically, as well as trying to learn I'm also trying to gather all the facts so we have another option to throw out there when people inevitably ask "can I turbo...". I hate the stock T series reply as I don't see the point in discarding the K when its such a lovely engine... other than the costs involved of course.

 

The cost for my conversion should be around £5-6k. That will be block rebored to 1.9L, liners, crank, pistons, rods, head work, charge cooler, methanol injection, Emerald ECU etc etc

I have the turbo, Emerald and am currently playing around with manifolds to get it 'up and running' before spending the bulk of the money. It all depends on what you want in the long run - I want an engine that I know can take the power of the turbo for everyday driving with the nitrous on top for the 1/4 mile etc :broon:

 

Honestly, if i was going for more power i'd go with a T-Series. In the long run it would probably end up cheaper and a lot more reliable.

That said, i picked up a 1.8T 75 a couple of weeks ago for £600, so watch this space.

 

lol @ gotenks1321... that sounds like a hell of a list xD. you'll have to show us that when its done

I'll see how things go with this... tbf the main reason I'm so set on the turbo k series is probably the same reason the others are... because its different from the norm :L

T-Series turbo isn't as special when so many do it... although I can certainly understand if its easier, cheaper, more reliable etc... lol

I'd be happy with 190~bhp anyway, so if a standardish 1.8T can give me that then why not :lol: I think I'm only getting about 130-135 ish from my 1.8 non-vvc at the moment anyway so thats a 50% gain!.

Every time something like this is mentioned though I keep thinking back to a Peugeot 106 over on 106owners.co.uk that has a huge turbo slapped on the 1.6 GTI engine and he's got it from the standard 120bhp all the way upto 410bhp :bigeyes: and he wasn't finished yet!

I wonder how much that cost :lol:

(rep given for helpful advice)

 

I think I'm only getting about 130-135 ish from my 1.8 non-vvc at the moment anyway so thats a 50% gain!.

118bhp IIRC!

 

Oh great, depressed me now :lol: ah well the less my car is now the better it will be when its bumped up!

I've heard people say its 118, some say its 135, one even told me it should be 152!!? Arrgh I'll trust you on this one though, you're generally the voice of reason in these waters....

And reguarding the video.... :facepalm: I posted that one just a couple of days ago lmao... that turbo is doing bugger all and is certainly not from a ZR. Also its a 1.4 in the vid not a 1.6. I appreciate the input though... but clarkson was a complete doughnut here :lol:

Anyway... I don't want to hijack this thread too much. Basically so far we know turboing a 1.4 is possible, and a lot of power can come from it, but it costs a huge amount. Better option is therefore either a T series, a turbo K series 1.8...or simply a bigger engine than the existng 1.4 and it may be enough on its own.

i know its a 1.6 but prob end up the same as if nothing else was changed and just put a turbo on.......

 

Sorry, it's like everytime I open my gob to you it's bad news. :dddc:

Surprised you've not added me to your ignore list haha.

 

lmao nah, ignoring people for giving good advice is pointless.

I'm just suprised you haven't got bored of correcting my mistakes yet :lol:

Gotta be greatful for the help you've given thus far

EDIT: Also, knowing that my car has less power than I thought makes me happy, not sad. Knowing I find it fairly fast now with 118bhp makes me know that it WILL be very fast for me if I can get it to 180bhp! Same thing with me and computers, finding a virus always makes me happy because I know I've found a way to make it faster.

 

Well there's something to be said for that.

I remapped a lad's car about a year ago to about 150-160bhp. I had a ride in it a few days ago - that power level by all means should feel fairly ordinary by now considering i've not driven a stock car for, well since I bought mine 3 or so years ago but christ it was quick!

I'm no stranger to power levels above that, but when you're in it it does make you wonder 'why do you need any more!'. If 150-160 can do that, 118 doesn't seem all that bad really!

It's not like it's an estate either

 

i'm quite happy with my 103bhp. gets me where i need to be in good time

 

My main problem is, I have to keep reminding myself that most of the time I don't need it at all because I'm in traffic or just running around town. When I do want it for overtaking etc on the main roads I don't need it for a long period of time but I do want it there! There's no motorways/dual carriadgeways on my trips so no overtaking lanes... bad.

Also it doesn't help there's nothing but hills where I live and I tend to put a lot of tools and computer stuff in my car that weighs it down... so a bit more power would be nice. To be perfectly honest, I know I don't need to break the 200bhp mark like so many people want to do... but anywhere from 150bhp - 180bhp sounds nice and would most likely be more than enough for me.

One other thing, can I get some more power on the cheap by fitting a VVC head? Someone mentioned it somewhere but I couldn't find any guide or post where someone has done it.

Aaaand if you don't mind me asking... is it worth me putting heatwrap tape stuff around my exhaust manifold as I spend a fair while sitting in traffic and my engine is lacking a heatshield on the manifold. The fan kicks in fairly often even though my temp and coolant are fine... which worries me a little.

Much rep and chips in return

sorry to say this, but i don't tend to get any traffic, i'm always going in the opposite direction...
most of my trip to work is dual carriageway...
and hills were never invented in the fens... :stir:

must admit 180 bhp in a ZR would be awesome, especially here where we don't have to fight gravity.

 

*sigh* fine well maybe ill have to budget moving home as well as a the turbo xD
