How To Tell If Had 135 Upgrade?

[winston]

Speak to Dave Andrews if you want to do any work on the K-series more than bolt on a few ally bits.

 

Decent exhaust, decat (excl VVC variants) and induction should see you very close to 140bhp anyway.

 

Agree, Dave's upgrades have a great reputation

 

Still can't see how you get 22bhp from anything other than taking the head off.

 

Dave's 135 bhp upgrade is cams and 155 bhp upgrade, cams + head port.

Only the 135R has the ally plenum etc the normal 135 kit was just a new head (exactly as Daniel and my car are)

 

There is no way, whatsoever of telling if you have it fitted as it's purely internal working.

 

If you want a bit more freedom, then the kit Anth has will help it breathe much more happily at the top end, you may lose a little low end grunt, but add a 4-2-1 at a later stage and you'll have a nice car.

It's true. Mine has a black inlet and the only give away is the stickers on the outside, and the fact that it pulls away from a standard car at very high revs and revs a bit higher before you have to change.

This has now really confused me

 

Mine has an aluminium plenum and is badged as a Sport 135

 

Before i bought the car i emailed Lotus and a very helpful man advised that would be the only good way to tell.

Is yours a Quiksilver coloured car with Red Corbeau Seats, Alcantara Steering Wheel etc?

 

If so, that is the official Sport 135 car, not just the engine upgrade, it has a host of other niceties also, but does have the ally plenum etc etc

No its an Ice blue S2 with black leather interior

 

it was definitely an after sales upgrade
