I Would make a 1.4 turbo mate

 

Having spoken recently to the chap at ZandF who would at a guess be doing your Remap.. You can achieve 192 bhp with a completely standard 1.8t engine. I'm looking to personally try to push it to the 200bhp+ limit. For this I'm going to be using a completely standard bottom end.. But with a VVC head and blanking kit, using standard Turbo cams. I'll also be fitting a FMIC to help with cooling.

 

You won't be able to use the standard turbo cams in a VVC head unless you get a special inlet made up, which if thats the case, might as well for for a piper 270 as it will be cheaper and readily available.

 

Also, it will be cheaper to just buy a turbo block as it will have everything you need, and won't require any drilling and tapping for the turbo send and return feeds.

The engines are pretty good on standard, but from my research and others, I think the liners are the weak point, so if you're going to build and engine get uprated liners, but the rest can be standard, which should you safely see 230-250BHP. Anything over that and you will need to look at getting a stronger crank...which isn't cheap.

 

How much are uprated liners for the K-series?

 

My understanding is that the journals on the vvc came are larger, but you can use any standard k-series cams, or piper k-series cams with the VVC blanking kit? I'd be tempted with better liners however it's a lot more work (That I'm not sure I'm capable of) than to just use a standard bottom end. I only want around 200bhp, not looking to push too much h further to be honest. I'll get another engine built up in the future if I do.

 

From my understanding, you can't get a standard inlet cam to fit in the VVC head without a lot of ****-arsing about. Same reason I sold all my VVC stuff as it would of been too much effort.

 

I think that's where the blanking kit comes in? I'd better have a read up again to confirm though.

 

All the blanking kit does is blank off the VVC hydraulic mech and the second belt area. If you look at a VVC cam and a standard K series cam, the VVC is physically bigger.

 

You are correct! Thanks for that!

Jus spoke at length with Mike Satur.

I'm tempted to just keep the VVC cams now and see what I can do with that. Hopefully not blow a hole in the piston.

 

Only problem with keeping the VVC mechs is trying to get the fueling right and also, you can't use them for big power. You will be better off getting a standard head and port & polish it (which will already make it better than a VVC head), some bigger valves (QED do a set for a really good price) and using either standard cams (1.8k and 1.8k turbo are the same) or going VVC exhaust cams or getting a set of 115/135 cams.

 

I've heard that is an issue, but with a FPR and decent map I can't see it being a problem. I know the last guy who tried to turbo his VVC blew a hole in a piston.

But I don't think he'd had it mapped sufficiently.

I'm not after big power, 200bhp would be my ideal figure.

I know the VVC mechs are a weak point but I wouldn't be pushing them any higher than they already go, I wouldn't need to.

Sorry for hijacking this thread.. But hopefully might give you a few things to consider when doing your conversion.

 

The bloke who did the VVC turbo had a map from ZandF (he also had an upraged FPR), but they are very reluctant to re-use it, so it would have to be aftermarket and will include a lot of testing/trial and error. Good luck with it though, would be nice to see the VVC mechs and turbo working positively together.

 

We did supply a base remap setting for a vvc turbo to cater for turbo map sensor/injectors etc with advice that fuelling and ignition would need to be further developed.
The car was driven on this set up though - hence the issues later..

The whole point of vvc is to gain efficient cylinder filling at all speeds - the turbo caters for this most of the time, with perhaps a minor potential gain off boost if the vvc system was involved properly..not sure of any significant benefits otherwise.

 

Has anyone thought of making a 1.8 turbo vvc?

Just do the 1.8 turbo conversion but then just stick a VVC head on?

 

Fail, didnt read the posts above..

 

I'm thought 1.8 turbo engines out of the rover 75's are non-vvc? i wouldnt be looking to go down vvc route & ive heard the 220 turbo engine's are very front heavy.

 

They are non vvc but some people want to vvc them also to see if it makes a difference..

I reckon it would be a nice little boost at 4-5K whenever the vvc kicks in..

 

I think if you could vvc the 1.8 turbo safely and reliably, id rather have that over a T16..

Not sure though..

I dont like the sound of the stress on the vvc mech personally and thanks for all the comments guys.

Will start to look into this 1.8K non-vvc turbo conversion more now :broon:

 

All these tf blokes have loads of money to spend on there hairdressers cars

 

You seem the price of a cut N blow these day's? It's rediculous.
