Hi, New to this forum and looking for some advice on restoring a TVR taimar turbo.

A few questions I hope you all can help me with:

1 - Did the V6 essex come with alloy heads as std? (they are stamped FoMoCo)
2 - What brakes will fit?
3 - Is the std diff LSD?

regards

Simon.

You really need to talk to Adrian Venn at Exactly TVR, virtually all of the turbo cars made have been through his worksho at some time. He is Adrian@ on PH.

Cheers for that i'll mail him , was talking to a ford parts specialist and a few other people in the engine parts trade about my cylinder heads and nobody seems to know anything about the alloy heads that are on this car , just wondering what has been done to it and if anyone has similar ?

I've never heard of alloy heads as standard, there are some NA cars with aftermarket ones.

Sad as it is all the standard turbo's are either bombs waiting to go bang or so far retarded on ignition that they running less than 190bhp (when the original delivery figures from Broadspeed are 218bhp......and factory figures of 230bhp)...Intresting, the alloy heads ....the FoMoCo logo denotes that the heads are pre '71 and most likely to be 'O' ported heads and not the later 'D' ported version that Turbo's would normally run, and a miss-match would be, possible but not desirable. Brakes are standard calipers with Ferodo pads, with riveted AND bonded special material rear shoes OR 4 pot vented with rear discs in both cases tyres are just as important. LSD's are not standard and the Jaguar LSD's need ramp rate changes before they get fitted, but the quaiffe internal unit is far better and the same overall cost in changing (jack the car up and turn the wheel LSD's turn the opposite wheel the same direction.

Thanks for the info guys...

Adrian what do you meen by O ported and D ported and mis matching?? (sorry if this is a bit of a lame question, know next to nothing about V6 essex engine)

about the bomb waiting to go off and retarded to death...

The car also has a 'micro dynamics' ECU??? front of which is a RPM limit setting, advance setting. and various wires labled 'over boost switch' - 'boost limit switch' - 'Ign advance' and, nearby, a adj. knob, boost adjuster i presume, labled 15 up to 30 (psi??)

The issue of 'O' and 'D' ported is an issue of the inlet manifold on turbo's.. a modified part ...is normally a 'D' ported and pre '71 heads are likely to be 'O' and would give poor flow ...less power. I, of any one out here, would be the sort of person to fit boost retard systems as I've done 30ish of them to TVR's and Broadspeed Capri's, yours sounds like a EMS5, but I've only used that on a couple of cars, one being my own, which needed to have supplementary fuel injection with a pressure realease system to give the car enough fuel at high speeds! and control the fuel on close down of throttle, but was running 292bhp (this system is long since gone, as my car is fully engine managed these days with lambda and idle speed control with projected figures of 320bhp). The issue of retard and bombs, should not come into play with this setup (although cooling and and the petrol tank might if they have not been sorted)...along as this has been setup and working correctly. It would intrest me to find out which car this is as I have never seen alloy heads on a car that I have worked, and if this running the re advance version EMS5 (as mine was) how the high speed fueling was sorted, I'm always willing to learn! 07956956042

Please excuse any lack of forum etiquete, this is the first time I have ever posted on any kind of forum, however, are you sure the FoMoCo stamping is on the heads and not on the inlet manifold, which is an aluminium casting.

Hi Neil, no sir, the newer boys and girls can do without me moaning about the good old days, at t'dairy! and how we used to lick motorway clean a'for being killed by our dad every night. AND how Vixens and M's are going to be worth more than Ha'penny.
Seriously ....two ha'penny. Have fun y'all.

Hell, bugger, get in there, the more the merrier.....I did think that too (I even went to look at an inlet manifold, but have no pre '71 ones in the workshop) the same rules sort of apply FoMoCO is pre 71 which is a 'O' ported era, that miss match of inlet manifold to the TVR turbo standard heads might be a better bet, and something I've seen often.

Checked it all out the heads are definatly alloy. adrian EMS5- spot on thats what it says on the box! got it started last night. oil looks nice and clean and there was good pressure. started and ran ok, sounded sweet. fuel pump knacked though! so d and o shape refers to the shape of the inlet ports? can see where power could be lost with that. can these be matched up with some *careful* work with a grinding stone?

Really am curious about the spec of the thing. could do with stripping the engine and having a proper look, but as it all seems to work fine will try and get it set up on the rolling road and use it until it is due a strip down.

Going to strip it all down (the car) and get the chassis blasted and powder coated then the rebuild. - more of a track day/hillclimb/sprint car I think. everything that doesnt make it go faster or stop better is going... will have a few bit and bobs spare if anyone needs anything (mostly trim/glass/seats etc.

STOP!!!! Arghhh.

Dont butcher your M turbo for the track. restore it properly for one day my son it will be worth a fortune. go buy a cheap 3000m and thrash that instead (says he who has butchered a series 1 vixen!!!)

You need to speak before to me before you carry on ..the fuel pump runs on a safety system and is run by the alternator via a diode system and so will not work until the car is running if you run out of fuel the car would need priming (there is NO way you would get the car running without priming the system unless this is directly by-passsed) in effect the car cannot be left with the ignition light on whilst running because at this point the pump relay is not keeping the pump running. My advice is NOT to override this setup as the fuel line can if not modified come off inside the air box and fill this and the engine/sump with fuel, where as if the car cuts out and you then look for the reason/fault you will not damage the car, also if you crash (god forbid) the fuel pump cuts-out. It is not possible to match O to D but, I'm not convinced that the heads are alloy (30 years of owning 58 TVR's and 6 of those Turbo's and having worked on hundreds of Essex engined cars, I've not seen any yet, it's time to put a magnet to the metal next to the exhaust ports. As for rolling road....be careful, the airflow needed to keep the exhaust and gaskets from failing (and standard one fail almost immediately, I do specials) is impossible to replicate, also the people who assume that they understand turbo system's and try to "Cosworthize" this car, invariable at the owners cost, are the people you need to avoid.....I have to assume that the work as it is of my doing (I would be suprised if not) and that's why I prompted you with which car it is....as for specs I have all the original build sheet info going back to minutes of meetings between TVR and Broadspeed when the car was conceived (218 bhp on 5* petrol and ran a 292 soon to be 320 bhp fully ECU'd version, and carry every spare assoc. with Broadspeed turbo's. They are still appearing and require 2000.00 pounds to get the car to run halfway decent, without- running hot, fuel starvation, breaking rear wishbones, poor braking, 222ish bhp (using today's unleaded) without additives, you appear to have a car that has had enough work done to it to make the engine safe, but you have very little if no control of the retard and re-advance systems within the EMS5 (this is why I stopped using that version and used the EMS6) with out sending the system back to Luminition to interrogate it.

Hey...perhaps a rear disc set for you sir, vented or solid...HO..HO

Having been a committed Turbo nutter B for many years I could not of said that,.... but MUST agree with you, the last person who tried had his original engine exchanged away by a firm that having refreshed, the owner complained because the engine would not stop blowing oil out of the dipstick at 7000rpm, the new to TVR Turbo's customer blamed poor build and rings, and they agreed and gave him a replacement engine that never rev'd to 7000rpm, it cured the fault....I did wonder where the hand finished block, crossdrilled hardend crank, special rods and pistons and many other parts went to....16 years ago (when I built that engine for my self) it was the only engine that I'd built that would hit 7000rpm AND if you filled the oil up to the top of a standard dip stick (the engine builders lost my modified one) it would blow oil out of dipstick and onto the exhaust and blue smoke would bellow out behind the car...needless to say he gave up running it and sold it to an unsuspecting new owner.
