TR4 V8 build

[cwin]

Thought I'd share a build I'm on with,I know some will hate it but i already have a near concorse Tr4 and fancy building one with around 500hp per tonne.
Brief spec is...new crate ls3 engine with new 6060 6 speed manual gearbox,Monaro diff, custom drive shafts,rear disc brakes,4 pot front brakes,full SW motorsport cage,

Car is going for dipping tomorrow before the new cills and floors ect get welded in. Chassis is being blasted and will have several coats of pain after any repairs and extra strengthening are done. The engine that's in is just a mock fit so the engine mounts an gearbox mounts can be welder in place.

Looking forward to seeing the result. Good luck.

I finished it in time for summer, it's very fast and handles really well, 480 bhp and same torque in under 950kg,

I didn't think anyone was interested in the thread so I didn't bother posting pictures of the build,
I have lots of them.

Hi Cwin.

Nice car, but you must have heard that before.

I am restoring a TR4A and thinking of wheels (and many more things). What type are yours and which size of types are on the car?
Are there spacers used?

Thanks
Hans

Sorry for the late reply, they are revolution wheels 7" in diameter, small hub centric spacers to get the right offset

Can you explain the plumbing and filters on the boot floor? (I get the fuel pump bit!)

Twin half inch outlets from either side of the tank running trough two inline (pre pump) filters to the pump, then onto a BMW X5 fuel filter ( high pressure) with built in pressure regulator.

Hope that helps

Two fuel filter AND the fuel pump UNDERNEATH the car? On an open panel? Without even a stone deflector?
Ludicrously vulnerable,IMHO!

I have fuel injection on my Vitesse. The pumps etc are all inside the boot, the fuel lines run in the recess of the chassis rails, as protected as can be, unless I ran them inside the car (no thanks! Not at 110psi!)
But hey! It's your car!

Tell me, how does BMW fuel injection deal with air in the line? You have a fuel outlet at either side of the tank, I presume to deal with surge, but the pump will draw air in preference to fuel if one outlet is exposed. Is there some sort of swirl pot between pump and injectors?

Hi John,

The pictures are of the car in a being built process, it has a nimbus grill heat protected shield covering it, it's pretty obvious as you can see no exhaust is fitted, but if I had put the shield on it before I took the picture you obviously wouldn't have seen it ? My fuel lines also run in the recess on the chassis, I have built and modified many cars including race cars and would like to think I know what I'm doing and can assure you I dont leave anything "Ludicrously vunrerable" Are you not aware that most OEM systems run the filters external and the pumps external unless they are in tank pumps ?

It isn't a BMW fuel injection system it's a Chevy LS3, I didn't say it was, what I did say was i have used a BMW hp fuel filter which has a fuel pressure regulator built in which uses the right amount of pressure for this engine.

No swirl pot needed the way this has been done I can run the tank to really empty even on the track,and why would it get air in the lines ?

Superb job mate, a fast TR4 was always a car that I wanted to own.

Had a few TR6's in the late 70's (nippy in their time), but they lacked the style of the TR4's and TR5's of quality, were out of my reach.

Your car looks great, small in stature but bags of style, with more than adequate pace to embarrass modern performance cars of any type.

Way to Go.

Thanks for the comments, it's ballistic fast to be honest, my son owns a supercharged Arial atom and this destroyed it....
