I have a Premier Power F175 upgrade. i am loving it. The Premier Power F175 has really transformed my 7 into something very special. The power delivery is instant, very smooth and a joy to drive across the whole rev range. As mentioned in previous posts I too can provide nothing but praise for Stuart's work and for the quality of the Premier Power product.

I have a Premier Power F175 upgrade. i am loving it. The 150 engine was great but the Premier Power F175 has really transformed the car into something very special. The power delivery is instant, very smooth and a joy to drive across the whole rev range. Stuart does, as mentioned above, work his magic on your existing engine. I was in a position to take advantage of rare opportunity to purchase a pre-assembled engine hence having my old engine for sale.

Caterham 150bhp Sigma engine for sale, 16000 miles. Complete with ECU, throttle bodies, flywheel and clutch. As removed from my car. £2250.00. Engine currently at Premier Power. Premier Power have offered to fit a new cam belt. Premier Power have also offered to install the engine if required for a cost of £350.00 inc vat. Please call Kevin on 07714767371

Have you thought of trying one of Premier Powers ultra light flywheel and clutches? This is what they have fitted to their F200 demonstrator and they recently fitted one to a 125 Sigma Caterham. This transformed the 125 Sigma making the throttle much more responsive, giving the car a very sporty feel. It also makes changing gear feel easier. Fitting these parts also means if you want a performance upgrade from Premier Power in the future, these parts will handle the extra power. Personally having seen this 125 Sigma, I’d say this is a better upgrade than going for the 140 upgrade.

Saw this car around 12.45 on the A45 Coventry Great day for us all to be out and about

Pete and Mo in the 21!! Car looking great. You were so close to my house , next time you're passing you must pop in Hope you have had a great weekend Thanks SM25T Edited by - K T Scott on 18 May 2014 20:52:34 Edited by - K T Scott on 18 May 2014 22:53:54

Green with yellow side graphics. Looks like you two were enjoying a trip out like we were Looks like you were spotted on the M69 too !!

Blue 7 - thanks for the wave -just caught you up before coming off at the Gaydon junction Lovely day for it !!!

Hi Pug 7 Interesting dilemma you are in but being the owner of a Premier Power F175 Sigma, I can highly recommend it. I was previously the owner of a Caterham 150 Road Sport which like others I’ve read about, had driveability issues. I can’t fault this upgrade or the professional service I received from Premier Power whilst the work was carried out. Premier Power won’t sell individual components for their upgrades as they insist they carry out the full installation of your upgrade to ensure it is set up to give the performance you have requested. The finished product not only looks fantastic but is a huge improvement over the previous engine I had and this has transformed the car. The throttle is very responsive, the car pulls very nicely from low revs and has a great sporty sound to it. There are a lot of people here that put the Sigma down and think you need a Duratec to enhance a Caterham. Now the owner of a properly tuned Sigma, I’m not convinced you need the extra capacity of a Duratec. Premier’s reduced weight Sigma punching out 175 bhp puts it in the R300 performance bracket and the F200 in an S3 car puts that in the R400 category and both are 20kgs lighter than their Duratec equivalents. Don’t just take mine or others comments on this, if you can, get down to their open day on Sunday 29th September. See the link on their website to register for the event; here The last open day featured passenger rides in a couple of tuned Sigma powered Caterhams. If you can’t make this date, give Stuart a call and arrange to pop over and see him, it won’t be a wasted trip. It’s worth visiting just to see their facility. Oh and I had to mention the comment about an oil leak on a 175 engine. Surely if it’s been put together properly and looked after should this really happen? These cars get looked after a lot better than some people’s day to day run about!! Funnily enough Premier Power have also got this covered. If you fit one of their Life Racing, Motorsport engine management systems, they have a function to shut the engine down before you cause any damage to your engine should you have a problem. In fact I believe these systems are now fitted to Radical Sports Cars to prevent engine failures. Premier Power ECU's Edited by - K T Scott on 6 Sep 2013 22:05:38

Hi All, I’ve been watching this thread for a while and find the comments very interesting. I have a 150 Sigma Road Sport SV and have to say I was a little disappointed with the fact that these engines don’t give the performance they claim to offer, as well as the poor driveability. The car has been plagued with flat spots and poor cold start driveability since I bought it and I have sent the ECU back for several updates with no real improvements. I’ve driven the Premier Power F155 when it was fitted in their demo car and even been a passenger in the car round Donington. I couldn’t believe the car only had 155 bhp, it felt like a lot more. The improvement in performance is magnified by the improvements in driveability. The throttle response is awesome and the induction noise sounds great. I’ve opted for the F175 option in my car and have to say I am very pleased with the result, it has completely transformed the car. Whilst I may have only done 1500 miles in my car, I’ve seen the testing that Premier Power have done with the F200 and have no concerns these upgrades have been fully tested for durability and engine longevity. As for Premier Power’s F200, well that’s something else. I feel a lot of the comments on this thread aren’t really justified in that the Sigma tuning market has only just started and not many people have yet experienced these cars. I feel that these tuned Sigma engines offer the best levels of performance for both driveability on both the track and the road. Let’s be honest 200bhp in a lightweight sports car offers most of us performance levels that is beyond most of our driving capabilities on the road anyway. I am happy to give anyone a ride out in my car to let these experience the F175 upgrade for themselves. With regards to resale value, I think this is Caterhams view from a Sales perspective with regards to control over the used car market. Having spoken to Stuart at Premier Power, the level of interest in their Sigma upgrades means I don’t think there will be any issues regarding resale values of these cars. Caterhams view on this is that they only buy used cars of standard specification. Well that’s fine, I think a lot of cars get sold on websites like Piston Heads these days or via the Lotus7club. I hope this hasn’t confused the matter further for you Greg, but in my opinion and experience, I would opt for a Super Sport with either a F155 or F175 Premier Power engine, or if funds permit, go F200. The Premier Power F200 Demo car is built using all Caterham parts on a series 3 chassis and weighs in just under 500kgs. Doing the sums, doesn’t that equal performance power to weight slightly over 400bhp per ton (R400 territory!!)? If you have any questions regarding these upgrades please let me know. Kev.

Hi Sparky, Have you thought about a bit more performance from your Sigma engine than 140?. Why not contact Premier Power, they offer conversions from 155bhp up to 200bhp. I own a 150 sigma and have driven both the 155 and 200 bhp Premier Power models and they are a big improvement over the standard engines. They also produce a very nice 175bhp upgrade. They even carry out the full conversion for you to ensure everything is set up correctly and you get exactly what you’re expecting. In fact Low Flying have just been on a track day with Premier Power to review the F200 Sigma in Premier Powers own Sigma powered Caterham, so this should be appearing in an addition of Low Flying very soon. Check out their website; here - Premier Power Cheers Kevin Edited by - K T Scott on 22 Apr 2013 19:03:48

I'm good friends with Stuart at Premier Power. He has developed three performance upgrades for the 1.6 Sigma engine. Premier Power has a lot of experience with these engines having run them in European Formula Ford with a lot of success. Stuart's previous experience is building championship winning engines for Nissan and Ford in the BTCC in the late 90's and 2000. In fact he still builds the 2000 spec Rapid Fit Ford Mondeo engines at Premier Power. The three performance upgrades are 155 horsepower, 175 horsepower and 200 horsepower. I've driven the 155 and 200 horsepower and have been very impressed. I myself drive a Caterham 150 Sigma and even the 155 Premier Sigma is a big improvement over this in terms of throttle response, driveability and performance. The 200 horsepower Sigma is great fun and Premier Power have spent a long time developing this engine to give this level of performance with good driveability and reliability. This engine has been the culmination of a lot of dyno work, rolling road testing, road driving and track testing to optimise the set up for the engine. They even have their own Caterham development car which is fitted with some impressive data logging equipment to help carry out development work. Premier Power is achieving this level of performance with the engine only revving to 8000rpm and with running 95 octane fuel. One question that Stuart often gets asked is how reliable is it. His answer is "we haven't had any issues, we often strip the engine during the development process to inspect various components and everything looks very good". "This is not a standard engine, but one that has been heavily engineered to last". Stuart's response to this question is that no one asks this question about an R500 which is revving to 8500rpm. Does the fact that it's got a Caterham badge or a Cosworth badge on it mean its immune to engine failures?. Another thing that's worth mentioning regarding the Premier Power Sigma upgrades is the weight of their engines. The Premier Power Sigma weighs up to 22kgs lighter than a Duratec engine. They have engineered the engine to be up to 8kgs lighter than the standard Sigma engine. Surely this reduction in weight puts their F175 Sigma upgrade in the performance bracket of an R300 or new Supersport R? I understand that Low Flying will be running an article on the F200 shortly as they are sending some guys down to do a track day with Premier Power later this week, so watch this space.

I have been talking with Premier Power re uprgrading my 150 Sigma engine. We have discussed a number of upgrade options including Heat Exchangers. Premier Power are marketing heat exchangers which they offer to fit on all their engines. The unit fits in the cooling system and not only helps warm up engine oil but also control maximum oil temperature. They say that a lot of engine failures these days are caused by bearing failures due to oil temperature issues. A lot of the engines fitted in Caterhams are modified standard road car engines and running on standard bearing shells. Because of the nature of these cars, cars are often driven too hard when first started, or too hard on hot oil. Its possible a lot of owners probably aren't even aware what their oil temperature is. Premier Power have done a lot of testing with these units fitted on both their race cars and road cars. Fitting an oil cooler can make the situation even worse, this will prolong the warm up time for the oil to get up to operating temperature increasing engine wear. The other thing, should you have an oil cooler fitted and suffer an engine failure, you will need to replace the cooler as you cannot guarantee there is no debris in the cooler. With a heat exchanger fitted, these can be stripped and cleaned. The heat exchanger doesn't need to be fitted near the radiator like an oil cooler, reducing hose lengths and improving radiator cooling efficiency. In their experience they haven’t seen an increase in coolant temperature, running these units. Improving oil temperature stability means your oil should last longer as it isn't having to work so hard, which therefore means engines should last longer. See link below for feature on their website. here As you’ll see if you run one of their management systems they’ll even limit the engine revs until oil temperature has reached operating temperature. Clever stuff!! I hope this helps

Hi I drive a Sigma 150 SV and have met the guys at Premier Power. As already mentioned above they are a very knowledgeable team. Following discussions with them I have found out the following: Premier Power have developed various conversions for the Sigma engine following success with the Sigma in European Formula Ford racing. They are constantly developing their upgrade packages and even have their own Caterham show car. As well as their upgrades, Premier Power offer products aimed at the road and Trackday market including motorsport spec engine management systems with built in data loggers, steering wheel mounted digital dash boards, carbon fibre air boxes and a very nice dry sump oil system installation. They also supply lightweight billet flywheels and uprated performance clutches as well as a very neat heat exchanger installation aimed at stabilising oil temperature. Premier Power offer a complete service where by you supply them with your car and they carry out the complete upgrade for you. I have also been out in their 200 Bhp Sigma Engined Caterham which is very impressive indeed. I understand they also have a couple of new products due for release in the middle of August so I would recommend you keep an eye on their website. Feel free to blatmail me if you have anymore questions. Cheers Kevin Edited by - K T Scott on 28 Jul 2012 19:24:32

Hi, does anyone have a spare set of Ford 1.6 Sigma Caterham front engine mounts I could borrow? We’ve just bought a new Sigma Superlight kit without an engine as we are fitting our own dry sump version. Engine mounts come with the engine from Caterham but they also do not have any stock of the mounts at the moment. We need to sit the engine in the correct position in our chassis to allow us to make our own mounts. If you do have a set of mounts you could lend us I would be very grateful. Please see below our contact details; t 01295 788445 m 07712 530858 (no signal during the day) e stuart@premierpowerengines.com Best regards Stuart.

Hi Dave, It was me!! On my way to Curborough to watch the Club Sprinting Championship Hope you had a nice drive out Hope to see you in a couple of weeks Cheers Kevin Kevin Scott AR Warwickshire 7's

Hi All I am the AR for the Warwickshire 7's. A new member to our meeting and the Lotus 7 Club has asked me to post this topic for some assistance from fellow club members. The car is a Sigma 1.6 built by the factory in 2007. Details of the fault below: The ignition switch is failing to shut off the engine. The engine will come to a gradual halt after some 15-20 seconds, and I am therefore stopping it with the external fuel electrical isolator. The ignition barrel has an isolator with it as well. Any thoughts and suggestions would be most welcome Many Thanks Kevin Kevin Scott Click Here To Visit Warwickshire7s.co.uk AR Warwickshire 7's (Warwickshire South)
