Speed Six Rebuild: Power 4.3 or 4.5?

I am seemingly one of the few that prefers the linear power of the 3.6 and enjoy revving it, much more so than the Chim 450 I had. This is why I know I will love the 4.3 - that will have more than enough power for me, for driving along our twisty B-Roads.

For me, if there's too much power all at once in such a light car, then (and I am basing this on my own basic driving standards) it is only good for 'point and squirt' drag races. I personally didn't buy a 2-seater sports car for traffic light Grand Prix's, I bought it to drive it like a sports car. For this, and for me, the S6 is nigh on perfect.

A 430 BHP LS3 would have been nice, but the cost is over double the cost of a 4.3 rebuild - and I very much doubt I would get twice the buzz.

ls3 would cost £5k more than a 4.3 if the numbers I've been told are correct, did Topcats quote you £24k for a Ls3 install?

You guys just sold another 4.3! Thanks.... I'm back on it!

LS3 running in your car for £13.5K sounds like a bargain Wolfy: http://www.powersperformance.co.uk/upgrades/43-lit...

IIRC Jelly spent £15K on bits and that was with a second hand engine. Most seem to spend £30K on an LSx conversion. I hate to think what Blackiepaul must be up to by now.

Funny the prices being mentioned, I know of a few 4.3 well north of £10k all in, and I had a quote not much more than a real 4.5 price for a full Ls3 conversion by Topcats

I had a quote from Topcats (not long after buying my Tam) - all in, for them to do the LS3 install with gearbox, clutch and all the other gubbins I mentioned earlier, the price would be around the £24k mark. I still have the email!

I know that the 4.3 is around £9k all in. If people choose to have new rads, clutches, lightweight flywheels at the same time, that still doesn't alter the fact that the actual 4.3 is still £9k, inclusive of VAT, injectors and starter motor.

ETA - That LS3 quote was just for the bog-standard unit, not the more souped up versions most seem to go for.

There are some imaginative prices being quoted in this thread.

From the Power website today

"Following over 12,000 miles of intensive testing, TVR Power has announced the release of its most powerful Speed 6 engine upgrade to date, the '4.5 litre Supersports'. This further development of TVR Power's highly acclaimed 4.3 litre Speed 6 stroker upgrade is to be priced at £8999 & VAT and delivers a blistering 392bhp and 344lb ft of torque at the rear wheels. Furthermore the only other parts you need to compliment the Supersports engine upgrade are a set of uprated injectors and a heavy duty starter motor, priced at just £275 & VAT and £195 & VAT respectively."

Music to my ears mate! Where is that on the Power site... Need to see it from the horses mouth and I'm booking in now

What other gubbins?

I had a quote much cheaper including new Ls3, Tko600 box etc full install,

New looms etc.

I don't know what else to say - perhaps they didn't want to do the conversion to my Tam, so quoted a silly price?

Doubt it - you wouldn't think that if you seen our house!

You should get a quote from the Guy who did the Winstanley Sag as well, by all accounts he is a top bloke and is very fair when it comes to price

TBH - I now have my heart set on the 4.3 Powers Performance upgrade. I like the S6 and am sure I'll like even more with a warranty and still taking it to the limit (after run in)

Looks like this will early next year now, though.

I agree love the S6,

Just find it funny when the price of a 4.5 goes from £8999 to £15500 unless it's had loads of extras (clutch rad etc) not disclosed.

I know - I think that's because the cost of bespoke remap isn't included in the price, yet it is required to get the most from the 4.5 apparently.

I am trying to get all the smaller stuff done beforehand, so I just pay the £9k at the time.

Just read back and it has had a few extras, flywheel etc, so that could explain the price and performance compared to some other 4.5 graphs posted

Thats where he hid the price lol

Right after reading all Im like this. I absolutely love the S6 and had my heart set on the 4.3... Now hearing what else should be done with the 4.5 and the "etras" Im sticking with the 4.3 as an upgrade. im already fully decatted ACT sport pipe so after the custom map for the 4.3 (currently running the EPROM upgrade) then it will be happy days. The rad I hear is not always advised. Im hoping I can get near 380BHP but maybe thats too wishful, light flywheel I must get more info on! So 4.3 for me chaps

[billynobrakes]

My 4.5 cost about £13000, where are you getting £15,500

I am on my phone so not at computer

And I have posted up Dyno results before

414bhp
368lbft of torque

Plenty good enough

4.3 are not going to have those figures

LS engines will be more

But then it comes down to the nut behind the wheel

I only went for the 4.5 as I had a bit of spare cash and thought sod it why not

I would have been happy with the 4.3 and have been on track with 4.3 ones and they was quicker than me

I would think that 380bhp is very achievable. The stock 3.6 came with around 350bhp out of the box. If you look back through the threads (way back to 2003 onwards), there are plenty of RR results confirming this.

IMOHO, if a standard good 3.6 has been well looked after and maintained, I see no reason why those figures should change from new.

With airbox,decat,exhaust,remap you are looking at 410 Bhp 340 lbft from a 4.3,
