What is the footprint of producing a new vehicle?

Hilarious, that's the way I pitched the cost to the missus

Over capitalisation big time does come to mind - the engine will worth more than the car. I would flog the car off and get something that better suits your need.

Yep, 4.6. Graeme Cooper installed the Interceptor after the engine build by Davis Performance Landys.

I picked up the Haltech off eVilBay.

Here’s what’s next;

Lots of tests and symptom analysis says that the low compression and oil usage of my P38 will require ring replacement in cylinder 2. Seems such a small thing to say it like that but will be at least a $5.5k fix including the bottom end rebuild and associated mandatory’s that go with that kind of fix.

Details – 175,000 kms, blue smoke on high revs, sooty splashes in the driveway below exhaust, using about 4L of oil (25W 60) every 1500kms, rubbish power in the low end, fine above 3000.

So, if i’m going to throw a good chunk of cash as a long term investment in keeping her as my daily drive for another 5-10 years i might as well do it properly.

Thoughts;
• Option 1 - Basic bottom end rebuild, head gasket, new radiator will be about $5.5k – this is the sensible approach. However, I’m a little worried of something else in the this 175k engine could be on the way out. Maybe I should start fresh?
• Option 2 - Long motor (new coscast block) with a stage 1 upgrade (updated heads, cam) from RPI will be about $8k landed. Installed? Would i then sell my current long engine? How much would I get?
• Option 3 - Long motor from triumph rover spares in SA – 5L upgrade (stroker kit and top hat liners), LPG direct injection – about $10,900. Will use my current engine for that price or exchange.

Timing – want to get this happening in the next month...

The sensible guy inside says go cheap and easy. The rest of me says to hell with that, let’s go hard and go as big as possible while buying reliability and enjoyment in a longer term investment with better resale down the track.

Would really like to get some thoughts on this one, any ideas welcomed!

Thanks,

Dave

I hesitate to suggest you spend as little as possible.

Get a 2nd hand motor with a warranty or just get your motor top hatted.

I live near TRS and their 5L is a monster job and not sure if the rest of the running gear is up to it as its aging also and the extra stress will probably kill it.

Perhaps even wreck your car, cut your losses and buy one where some poor person has spend the big bucks already.

i have the TRS 5 liter in mine and they make the car worth driving. it got nearly 1000ks on it now and it keeps getting stronger every day. the engines come unbalanced and un assembled so unless you have someone that can build it for you or you can do it yourself its a massive job. mine ended up taking 9 days from starting to pull the 4L out to the 5L running. it now chirps the tires on launch and averages 4L/100k better on fuel than the 4L did aswell. I also had to upgrade to the 4hp24 too.

"Over capitalisation" "spend too much" "Buy another RR"

No way if you are into your P38 keep it, if you spend $10k on it you are certain to have a good rig and with the 5 litre in it she will go very nicely
