Oof! Made a bit more progress today. My week off is running out quick though and it is frustrating waiting for parts  Finished off the oil return pipe  Drilled and tapped the plenum for MAP sensor / boost gauge takeoff  Fed the pipe through an expertly driller hole in the bulkhead  And teed behind the dash to feed the ECU and boost gauge sensor I also wired up the boost gauge so it is all ready for the new dash to turn up   On top of all this I also replaced the engine bay flexible fuel hoses with Gates Barricade fuel hose (£30 a meter!), as the R9 hose that I put in 18 months ago had already started to deteriorate. Drivers seat also removed for bolster repair at the same time. Quite a busy day and a lot of small jobs done |

Good work - love this project and can't wait to see it come together and be run in anger! Cheers Matt |

Interesting work. Check out my twin turbo moggy build as they have a lot in common

Is that an MS3 i spy in the back ground? Nice gauges too, always wanted nice gauges! |

Big progress today. I might put a picture up on Pistonheads for a bit of controversy, as I am sure it will divide opinion. I started by removing the bonnet supports as they were fouling the intercooler pipework. The bonnet is still rigid without them so an easy win. Before:  After:  I also got the blanking plugs through for the original breather ports on the plenum   Boost controller (now relocated to the other side of the rad for clearance as you will see in the later pics  Now onto the big stuff! Wastegate pipework made up and tacked on  Looking loud 8)  *not* a TVR's best friend  Butt clenching time  Phew     Still lots to do but it has been a good day  |

I just don't get it!? You have very nice car and reasonable turbo upgrade....and you're gonna use DIY MS2 !!!  ? |

not sure about venting through the bonnet...whats the thinking there?

It was not DIY, it was built by Phil at ExtraEFI and the loom built by Shaun at MS2 tuning, so it is by no means a 'bodge' upgrade and the car has been running fantastically on it for over a year. Do you think it would be better with the standard Lucas ECU and distributor?! |

The 'kit' turbo upgrades have it fed back into the exhaust but where the exhaust is not a huge diameter anyways (and i had to step it down slightly at the turbo outlet due to space constraints) I am reluctant to run the wastegate back into the exhaust and risk boost creep due to the restriction. It is a fairly common routing for a screamer pipe (albeit in the J / drifting crowd and not normally on a TVR) |

It is not N/A anymore. It is turbocharged! ... and it needs much more control options as well as 8x sequential ignition and injection. I'd look at MS3X or MS PRO at least. |

wouldn't you just be better giving it a bigger exhaust?..

I have proven that it works, along with many others across the pond that an MS2 will run a V8 plus a turbo/blower without issue . Wasted spark works fine for a turbo application and so will the batch fired injectors. EDIS 8 may be an issue if you need to run less than 10 degrees advance, or a spark cut limiter as it doesn't allow this, but i just modify my ECU's to use 4 spark outputs so it cuts out the need for the EDIS unit. MS3 is way overkill on a rover v8, unless your wanting major power or just want to over complicate things. |

Nothing is overkill when you could save your investment. The wasted spark is a compromise used mostly price wise as well as the batch injection. I know, even ms1 can control a V8. It is strange for me how much money people would spend on rims, paint, XID, exhaust....etc but would rather save on engine control...because "it must be simple". P L A I N wrong! ...And that Turbosmart "Boost controller" screw is a joke. You should use proper boost control with closed feedback. And yes, I like MS units, especially the higher level ones.
Let me poke few question just for food for thought: How do you know whether all cylinders have eqal VE(filling) or not, based on a single WBO2 or EGT? How many owners/tuners log the IC efficiency (inlet vs outlet vs ambient temps) during longer full throttle runs? How many log oil temperature? How many care to use knock ign. control, not only a detection LED? How many of you believe that a cooling system designed for 200hp NA car/engine is also good for 4-500HP turbo engine, especially when most of the front radiator area is usually blocked with additional IC's, oil coolers, bumpers.....etc? Do you belive all cylinders have identical cooling? Do you think that logging the fuel and oil pressures and creating ECU/engine limp home modes when some treshold is reached is an overkill and waste of time? It doesn't matter whether the engine is an old V8 Rover, Audi, BMW or else. The good things are always a complication, but luckily you're doing them just once, when it's the right time for that.
I just like that car very much but won't bother you anymore with my worries. It's always up to the owner to decide.
Just my 2c.

I know exactly what you mean about spending loads on making a car look cool, then skimping on the essentials for the motor/suspension/tyres, But what you have just summed up is the difference between spending £3k on an ecu setup + tuning costs and £700 on megasquirt and having a go yourself. Most folk also don't have access to a dyno, so paying someone to do solid state tuning for each map, on each cylinder would probably cost more than the car, let alone the engine you've just slapped a turbo onto! Anyway, we could talk all day because you clearly know a thing or two Vagvaz, but i want to see the next update |

Hmmm, looks like someone's swallowed a text book to me? Wasted spark and batch fire isn't the way I'm doing it but it's fine for most production cars so why not good enough for this? I agree, closed loop boost controller a must although I would worry more about the inlet tract and poor flow characteristics and starving or robbing boost from adjacent trumpets and inlets in the plenum rather than boost creep and exhaust size. It's an FI engine so unless you have a pee shooter exhaust it's being forced out so diameter isn't THAT critical.
So far, it all looks good enough to me for a road car. Are you fitting forged Pistons? What CR and boost you running?

I got some more bits done today but will save the next update until next weekend. The way this conversation is going its a wonder turbo cars with carbs and distributors even managed to start  There is nothing wrong with a good quality manual boost controller, they have been used successfully for a long time and on a LOT of cars without issue. I may go to electronic boost control in the future as the MS2 has the function to run it, but at the moment I want to keep things simple and actually prove that everything works. I will also add that the majority of TVR turbo conversions that are currently on the road have been completed in kit form from the likes of TVR Power or TorqueV8, and are running with a slightly modded distributor and standard ECU. You may be surprised to hear that these are still successful and simple conversions with many happy customers but this is not the way I wanted to go and wanted to do things myself and my own way. Generally this forum is quite upbeat which is why I decided to post my thread on here. I appreciate you may do things differently yourself, but it is my car, and am putting a lot of thought into my decisions. I appreciate input and ideas from members on here, but maybe with just a less derisive tone |
