Update on the build, the exhaust manifolds have arrived at Zircotec so there will be an update on these hopefully next month once they have been plasma coated.

From Dom at Powers on his Facebook page earlier today:

fk me, the Titanic will have rusted away before this is finished!

I the mean time, tell me more about your Astra.

This does look seriously cool! Bravo!

This engine will cost more than a whole car off eBay

Money is just paper or now just a figure on a screen,,, this is real and tangible.
Bravo indeed Matthew, you always had a look in your eye,,,, classy

HURRY UP!

An issue not not accounted for was the with the increased stroke of the crank I needed to address clearance on the sump. TVR already had this issue with the TVR500 engines and they used a press to provide clearance.



The OEM sump on the car had already been modified by Mulfab to install internal baffles as part of a group buy kindly organised by phazed. Despite chasing I was not able to receive a quote from Mulfab to modify the sump to clear the new crank. I found a company called SiFab who also specialise in Rover V8 / Morgan bespoke fabrication work. I discussed the issue with Simon and he recommended rather than welding a shallow trough on the front of he sump he may as well weld a larger piece on and increase the oil capacity of the sump. I opted for the optional windage tray as well.

I am very pleased with the result from SiFab:

I, and many others i suspect, have seen the pictures posted by his Domness of the completed engine.
Have you now got a timetable to completion, Matthew?
It would be good to compare it's performance with my lil' ole 4.6 turbo.

Exactly what has prompted me to update this thread as it is woefully out of date. Still a fair bit of work to go converting over to ITBs but I will keep this thread up to date with progress.

Performance will be not even close to your 4.6 Turbo!

Lots of intricate work in the sump .. you're probably ahead of me here but have you checked for clearance to the chassis triangulation ?

I am hoping it will be OK. I took this picture as square as I could under the car and it looks like there is clearance. It is going to be close

Dom and the team at Power have completed the build of the engine.

Final specification:

TVR Power bespoke Taraka 5.3 engine rebuild
5.298cc engine capacity
Compression Ratio - 12.36:1
Doug Kiddie 91.5mm crank shaft
JE Lightweight I beam forged connecting rods
JE Lightweight forged pistons
JE Short DD inlet manifolds
DD Jenvey throttle bodies with ITG filters
Yella Terra Billet fully cradled roller rockers
TVR 377/21 Solid camshaft
Solid lifters
TTV Billet flywheel
ARP bolts
SiFab baffled sump with additional oil capacity and windage tray
TVR 500 heads upgraded to Taraka spec cc'd and port matched

Jody at Python Racing clearing a slot in his availability to prepare the car for the engine to be fitted. There are a number of decisions to be made around the fitment of the ITBs including sorting the brake vacuum system, crank case ventilation to catch can, oil cooler, PAS reservoir relocation etc.

Once Jody has worked his magic the car will be back to Power fit the MBE ECU and commission the engine.

Looks very pretty!

before you settle on a final induction you might want to read my thread from a couple of years ago here, don't throw away power by running too short :

My extended Mulfab sump had plenty of clearance.

I use an electric vacuum pump to assist the brakes.

Lovely job Mathew.

[andy43]

Do like those throttle bodies. Proper job

[mk1fan]

meh.

Very nice Matthew

Yet another quality job performed by Dom and his team. Worth every penny I would say.

Very very sexy from top to bottom, love it.

Should produce some serious power especially with that compression & cam, what size are the throttle bodies?

Respect sir.
