    Default At a loss - need advice

    I've owned my Seven for 4 years now, and it has run properly for maybe 6 months of that time. The problem has been with poorly executed engine rebuilds. I've had 2 different shops rebuild the 2.0 Duratec. The first rebuild was done by TMW's shop and it never made oil pressure (among dozens of other issues). The second was done by Colvin Automotive here in Austin. It had a miss, and compression was 20lbs low on cylinders 3 & 4. I pulled the head this weekend and it is obvious that metal was left in cylinder 4 and bounced all over the place, scoring the cylinder walls, piston, head and valves. Fuuuuuuuuuudge.

    So basically I have 3 options:
    1) Find yet another shop to rebuild the engine again (recommendations appreciated)
    2) Buy a built 2.3 motor our of the UK. Probably Dunnell because Costworth is just too pricey.
    3) Buy a running Seven and use my current car as a parts donor

    Thoughts? When this thing runs it is glorious and amazing. I'd give up on it if I could, but nothing I've ever driven has come close to the entertainment factor.

    Not knowing the shape the car is in, I’d think scrapping the car because the engine is bad would be like tossing the baby out with the bathwater. I’d say get the engine issue sorted (rebuild/new engine) and press on with the current car.

    Yeah, the car is great. Even more so since I've gone through it and reworked several things. Turning it into a parts car does seem very silly. I'm researching engine options - the 2.5L Duratecs look fun (I know that is still tiny in you perspective!) But wow are they expensive. $15-20k is a lot, especially when the 450 bhp 6.3L in my hot rod cost less than $4k.

    Our cars are plug and play. So scrapping the car because of an engine issues seems extreme - I agree with Suave above.

    With that in mind then use the chance for a serious upgrade in performance. Options:

    1) Why stop at just 2.3L...wimp! Bruce Beachman does a nice 2.5L Duratec option.
    2) Dunnell used to have a proprietary ECU which is a big downside to my mind - not sure if that is still true but as an alternative maybe look at Raceline http://www.raceline.co.uk/ or Burton Power (p 14-15 of the catalog) for crate engines
    3) While I have not, a number of forum members on the east coast have used Quicksilver race Engines http://quicksilverraceengines.com/services.htm
    4) Do you have a Caterham? What about dropping the 620R powerplant into your chassis?

    Croc, you know that the 620R set up only has been done with Right hand Drive cars. Don't tease the guy.

    Have you considered rebuilding the engine yourself? Success is mainly related to cleanliness and attention to detail. Clearly that was lacking on your previous rebuilds. Doing it yourself allows you a lot of control plus it’s a great opportunity to learn.

    I can vouch for Quicksilver. They have built a number of my engines and they know what they are doing.

    May suggest a locost approach? Find a low milage stock 2.0 engine from a rear end collision focus. A low spec engine is better than your flintstone-mobile. Do the work yourself and should be running for a few hundred bucks.
    What ECU/setup do you have?
