5a engine swap

Post by Marko » Sat May 05, 2018 8:29 pm

Thanks Peter we haven't been made aware of any of that over here yet as fast as I know. Although we are usually a few years behind the mainland where mot and road regs are concerned.

Darryl just noticed you are a local man... Where abouts are you based? Do you know anyone who is well versed in Essex engines over here?

I need to get a progress thread put together but my life in the last 2 years haven't exactly allowed me to focus on the cars at all. I currently have 3 5a's and a 5 1 of which is still functioning, 1 of which is off the chassis, 1 stripped and was originally intended to be refurbed for historic rallying but has been left for the last 5 years (was my dads) and one (the 5) bought as spares.

I also already have a supposed 'big' Essex from an old auto crass type car with a set of triple 42 dcnf's. But I would like it rebuilt before I would install it

Well that could potentially change the answer, got to be worth pulling apart and checking before you make a decision?

The mot regs and engine swap only apply if you want mot exemption, personally, I think if you modified the car with a quicker engine, it should be well within the owners grasp to get it through an mot......the amount of effort and problem solving to get a Vauxhall or Saab engine into a scimitar makes and outrigger weld or trunnion replacement a walk in the park. Plus you get a bit of paper to say it’s been checked. :D

At what point does an Essex tune up become 'expensive'.

Using the law of 'diminishing returns', what gives the biggest bang for the buck? And how much will it cost for what power gain?

I’d say 150BHP is easy, 180 will cost and 200 is expensive - anything over 200 is going to cost more than an Omega donor :D

The Essex responds well to modest tuning.

Tubular exhaust, air filter, jets, and a modest cam. This should give an honest 150 bhp. and still have decent fuel consumption. Triple carbs will drink fuel and cost a small fortune.

I do know that insurance in Ireland can be a minefield, and modifying it could be suicide.

IF you could have put your location in your personal info it may have helped some of the contributors in their reply's.

So,

Going from the above comment:

"Tubular exhaust, air filter, jets, and a modest cam. This should give an honest 150 bhp."

If buying from new:

Tubular Exhaust manifolds - £300
Air filter - £50
Modest cam - Stage 1? - £200
Dyno time + jets - £100.

It sure puts it into perspective, assuming you started with 138bhp, that's £600-£700 for a modest 12 bhp increase. Okay, so nobody really believes that even when new, their engine made the reported 138bhp. So the hike is more likely to be in the 20 bhp range?

No doubt it can be cheaper if serviceable parts can be sourced second hand.
