just after some personal experiences hear before i commit to anything.

ill be looking at getting a rebuild done soon sonwhat option did you go for and how did you find the results and the experience with the builders.

tvr power have a lot of options which os considered best?

theres also some good reviews for str8 six. anyone got any experience of them and or how the 2 company's compare?

is there another option i should consider?

id be happy to tackle the the job my self using local independents to donthe machine work but i guess this wouldn't look as good come resale time?

I got Dom at Power to rebuild my 4 litre "S" as a 4.5 Super Sport then got the upgraded MBE ECU with anti knock sensor etc.
Very pleased with the workmanship and keeping me informed and on schedule . I was disappointed I didn't get my anticipated 400bhp , but the general characteristics of the engine suit me , with loads of torque across the rev range and a lot lot smoother than original. I don't rev my car to excess so the peak bhp is inconsequential to me.

The LS engine swap never really took off did it despite apparent cheaper running costs and superior reliability? Personally I’d rather buy a TVR with a rebuilt S6 from a reputable source than an LS.

At the rolling road shootout the S6 engines rebuilt from STR8SIX stood out as the ones that were meeting or beating the expected power outputs.

Their 4.3 conversation making around the 420bhp mark in nearly all cases. One of the cars was a 4.3 rebuilt nearly 10 years ago and well used still made over 410.

The same went for the other engines as well.

My 4,3 - rebuilt in 2012, made 412.9 bhp at the Surrey Rolling road session December 2019. The car now has ~ 102K miles on the clock....the last 55+K miles on the refreshed engine.

I'm pleased with the service I get from Jason and all at Str8Six..

What’s not to like is not a proper TVR Tuscan without the Speed Six in it...

Had my Speed Six done by Ian at TrackVRoad, used because they looked after the car for 10 years prior to buying it, very happy with the work and the service

Had my S6 rebuilt in 2010 by Powers. Standard spec as at the time the 4.3 had only just come out and I couldn't stretch the finances. 30K+ miles since then, regular servicing, sweet as a nut, probably done half of those miles in France and Germany so used more as a GT.

Never bothered with a rolling road or power output willy waving, it has enough power for the cars weight and it is smooth and responsive. Think about how you will use it - modern roads (potholes, MLOC and speed cameras) limit how much you can really use any additional power, and why does it matter if someone can go faster "in extremis"? More important the car is reliable from the off.

I had my Mk1 4lt Tuscan S6 rebuilt by Jason at Straight6.
Pleasure dealing with them.
I also later had an upgrade of roller bearings in the throttle bodies also done by Jason.

The next 20k miles where a dream before I wrote it off. frown
