Just had a look at the carliciious one too and here is what I can see; 1. I'd personally choose the 0.82ar for a road car on the GT35 2. The intercooler is a budget one, it's the budget option I chose when piecing together such kits 3. Exhaust manifold is cheap ebay one from China by the look of it. 4. Wastegate is a cheap one from China by the look of it

They know what they are doing in terms of tuning (at least X-parts does with their Turbo Impression car, not sure about the others), but I have had a few owners state they have bought things like German manifolds and they did not fit very well due to the slight differences RHD to LHD. Something to take note of.

Yeah I like the EFR range too, fantastic turbo's, I'm hoping to do a twin scroll 8374 in the near future on either a VR or 4mo - my trade supplier is Turbodynamics too so let us know what they quote you in future and I will see what I can do in terms of best prices.

Normally £1150 + postage for the v-band option on the GT35R but I'll do it OC members for £1120 all in std UK postcode. Best to e-mail directly in future at; sales@rbpe.co.uk or rbperformanceengineering@hotmail.co.uk CHeck this thread for EFR prices, they can fluctuate a touch but you get the general prices and discounts offered http://www.vr6oc.com/forum/topic/46270-vr6-oc-borg-warner-turbo-discounts/

Usually they are £1035 + postage for the T3/4 bolt but I will get you a new quote and let you know on here as soon as poss (probably tomorrow now), as they often fluctuate from my supplier. Probably a bit more for the V-band. For that one I would also knock off some money and do it you as an OC member for £1015 all in if you have a usual UK post code but I could also do an EFR 7670 at a similar cost as I get better discounts if you want a quote on that too?

I am not sure of the mods but the data I saw about the oem unit said a 56mm inducer - the ad for this one also says that but I do not know if the 78mm compressor exducer is larger than the one on the graph I plotted. It is, however, 2mm bigger than a GT30 so should be good for 52-54lbs/min (or about 550hp) at a guess. Looking at the ad it has a turbine side of 66mm which is 2mm smaller than the 67lbs/min GT35 turbo so lag would be similar to that but the GT is DBB etc which means the turbine side is good for 600+hp if it wasn't restricted by the smaller compressor side. So who knows - this m

Sorry, forgot to mention - if you have to stick with the turbo you have, have the 3.75" taper down to 2.75" or 3" fairly quickly, don't make it too much of a change at the outlet though in case you introduce turbulent flow, but the longer it is a larger hole, the slower the gas speeds will be and the worse the low end response will be if that is what you are aiming for! https://en.wikipedia.org/wiki/Moody_chart https://en.wikipedia.org/wiki/Laminar_flow

Just had a look at the comp chart for the HY35 and have plotted a graph to show you; 95% VE, 6800rpm rev limit, 100degF temp etc - about right for a stock VR: As you can see you are going to be pretty much out of efficiency at every level even on a relatively stock engine with that turbo - the one in the ad could have a slightly larger chart but not by much I would think! It's also why the ad said it's for high boost as they are diesel based turbo's so good for small 4 cylinder engines with high revs, high boost as the chart shows from 1.5bar to 2bar. (2.5 to 3 on the graph for about 450h

You get the url from youtube and use clipconverter or keepvid - of course this is theoretical as there may be IP rights involved and they may not want you to! I prefer this one as it is THE BEAST!

It's flame propagation problems and so on that usually bend rods! 3.75" outlet is MASSIVE - bigger than 750+hp turbo's I sell (Garrett/EFR). In terms of gas dynamics it will certainly lose bottom end being that big, it's probably designed for the high revving engines the ad advertises and the turbines are always massive on those turbo's as they are designed for high boosting diesel engines! Couldn't see the AR ratio on the add either which would give you an idea as to spool. So, you'll now have to go from 3.75" down to; 2.5-2.75" (300-450hp) 3"-3.25" (450-625hp) 3.5" (650+hp) and so on fro

VR powaaaaahhh!!!!!

Rule No: 1 - if you are going to add forged parts, make sure the engine is fully stripped down and all hones, alignments, cracks etc are checked, otherwise you are just wasting money on forged parts. Gas can bypass the rings on older engines where the cylinder bores are not as perfect as they once were so if that is checked and okay, just get some new rings. Not sure on the oem spec of material for the pistons but 4032 actually holds up better at prolonged temps over the 2618 alloy also used - the 4032 also does not expand as much and so has less rattle (although you can get them coated nowa

I sell them, which one are you after?

Apart from ebay there is the choice of having some Chinese dude fab you one to your spec, they are as cheap as the bay ones but usually you need to order two or three at least for a few hundred quid outlay. Apart from that I usually get Forge to fab up a custom item or people like Allard do them too - you're looking at £600-750 most likely with them though for a custom item.

Hi - it doesn't quite work like that. This is what happens - my supplier forges them in-house, then sells them to big companies like Skunk2, hundreds at a time usually, who advertise them as their own rods - I can also get my own corporate logo on them etc if I want and do the same but I thought I would do it as a Group Buy to see what numbers I can drum up. As these are major forging plants you need to order at least 60+ units, sometimes 100+ in order to justify the tooling costs (same as in the UK). In order to do this I need to get the numbers to justify the costs - £9k was my last toolin

What you running now for the fuel pump? I like the Black Ops injectors, they're 4 hole pintle's too so really good atomisation - quite expensive though. Apparently they do them in direct fit but I am sure they were the thinner EV6 style they showed me but according to 5-O they are direct fit for the VR6's. These are the dead times for the more popular injectors used;
