We are hoping for 230bhp and 350ftlbs with the gtb1756vk and well the figures for the bv50 turbo will be for heavily modified pump and injectors along with forged internals and a huge fmic and 2.4bar of boost for hopefully 300bhp and over 400ftlbs. the car will be done in due course but with a lot of attention surrounding the outcome we want a quality product with a reliable setup, the car needs to be able to compete in 24hr racing so we need to make sure it spot on.

the option for a gtb22060vk kit was in the pipeline but due to it being hard to get enough supply cheap enough for customers we opted for the gtb1756vk and bv50 which are far easier to get hold of and rated at 240bhp max and 310bhp max.
O no, don't let my boy see this lol, seriously though this looks like a terrific project, what do you think the ball park figure will be for the 230bhp kit as I can see this being one of my many jobs on he`s ZR

Is this solely for a track car, or would it be drivable under normal road going conditions?

As a few people on here have encountered head lift with the goal of getting more power from our humble L series, have these issues been solved with the track setup?

In regards to gearbox/clutch, i assume these have been upgraded, if so, what is the spec/cost etc?

I really do hope the power figures will be achievable, and are reliable for long term.

Good luck with the project

Cheers
Dave

not sure yet till we have development finished and some graphs and track proof. then we will offer group buy options this way it will bring the overall costs down people can also get their own turbos off ebay second hand to bring down costs but we will only be supplying new units.

to give people a idea of boost expected we are expecting 1.4 bar to be availiable from 1500rpm and full boost 1.8 bar by 1800 rpm this should mean we could be looking at up to 270-280ftlbs at 1500rpm this was one of the main choices in this turbo as it will provide lots of power from very low revs while being able to provide a good top end figure.

sounds good, keep us updated and any track news would be great

these kits are being built on a car with around 17:1 compression and with a paddle clutch, the lowered compression with the bigger turbo will lower emp and reduce headlift early results are promising and the car will be undergoing a 24hr endurance test when its ready so if it can survive 24hrs flat out racing im sure it will handle day to day use, the kits are being designed for normal driving and road use also.

the clutch price was around 280

Would a decompression plate be a prerequisite for all the proposed turbo upgrades then? 17:1 is quite a drop from 19.5:1!

yes we are using a decompression plate but we needed to be able to handle up to 2.4 bar of boost so 17:1 is fine

YES! Go on Matt!

what type of VNT actuator will these turbos be using, vacuum or electronic? will they work on the facelift OBDII cars?

i'd be happy to see 180hp/280trq would the decomp plate be needed for for my goal? or could i get away with dropping to 18:1 for example?

time to get saving and ebay my wastegate GT17 i recon!

the kits are being designed to work with the non facelift models at the moment with the egr control for vnt control, once they are done we will start the long and costly task of working a way round for the face lift models at the moment our only option is to put non obd2 software in the ecu so it doesnt have the fault code issues. A .5mm decompresion plate should take you to 18:1 which should be fine but gain we are only creating the mapping for our setup so it will be unknown how the car will behave on 18:1

Certainly interesting to read about the updates and the two spec's of out the box upgrade you are creating and testing.

full boost would appear to be about standard then, so it would make it better to drive than the stage 2 hybrid in fairness, i will be interested to see the torque curve though.

However that said what is required is quite a step up for most people in order to get it to work effectively - eg this upgrade will require, FMIC clutch, gearbox (diff) head off, belts etc....

You using standard head bolts for this, or gone ARP?

I wait to see how it all pans out... and it might well be a route i follow later on - eg if i blow the HG again and the head needs to come off

Good luck with it though

I know it may be far off yet but any chance of a rough ballpark figure for the 180bhp kit?

Ive allways wanted around 200bhp, that has allways been my overall target

We are using stock bolts we believe they will be strong enough with low enough emp and compression. Full boost will be 1.8 bar so much higher than standard and expected 350ftlbs the kits are being designed to make a reliable car it's up to other people whether they fit all the mods and how much power they require.

We won't release pricing until we know 100% the cost to us our kits are being designed to break 200 bhp with room to spare the bv50 kit we expect to have to modify the pumps to get past 230bhp.

Just had a re-read through the thread, nothing (as far as i can see) has been mentioned about injectors.

Is it stock injectors/SDi's/Wingy, or something more hybrid?

Cheers
Dave

We have custom injectors and Wingy for this setup and we will test both to check for flow and atomization

You would have to find a way to control the turbo as we can use erg control on your car to control it. we are looking at controllers to work with the electronic actuator. Fitted as standard to the turbos.
