The EFR Turbo Thread

Thanks Dann. Wouldn't do that then, as want to be able to use some or all 98 from time to time. Clearly a proper turbo and exhaust is the way to go. Any vultures for a high flowed IHI and a full 2.5" exhaust system?

Dann, just re-read your first reply - it's a pretty good advertisement for the EFR, not withstanding what I could to to my current set up to get more put of it.

The comment that the EFR turbo-ed mx5 'feels like it's had big engine swap' and not a turbo, comes up on the American forums - it's surprising there are not more local accounts of EFR based builds.

I'm looking at an EFR for little red.

gcg have four flavours of EFR 6258 available:

V-Band intake flange w/ 0.84a/r
T04 "Dual Entry" flange w/ 0.80a/r
T25 flange w/ 0.85a/r
T25 flange w/ 0.64a/r

Which one would I want for a 1.6? (or a 1.8 for people that aren't me)

I'm guessing the T25 w/ 0.64a/r compressor will be all that's needed on the 1.6 due the the lack of displacement. I don't know for certain, but it looks as though the T04 Dual Entry flange just dumps the gasses into the same collector (so it's not actually a twin scroll, I dare say Dann will correct me if I'm wrong here)

Yeah the 0.64 T25 entry is what you want.

Our cars started out very similar, then we did our own mods to have a few differences and now they are back to being similar. How soon do you think Lil red will be up and running?

At my current rate of progress I should have a fully installed and configured turbo in approximately ONE MILLION YEARS! :shock:

I don't have a shed at my current house, so if it's dark or cold or wet, nothing happens on the car. Needless to say, there has been a LOT of nothing happening lately! :lol:

Fair enough. I know what you mean. Even though i have a garage, I had no power in it until this year. That was 4 years without power!
I'm looking at January to complete mine. Any sooner will be a bonus

Biggest problem with the EFR is it is so effortless to get to speed crazy fast. You'll perpetually have "one day this car is going to kill me" in the back of your mind, even on wastegate pressure. Then you'll sell your car because you realise it is true. :lol:

I haven't dríven an MX-5 with one of the new GTX turbos but my EFR setup would spool much quicker than an SP and not choke up top like a smaller turbo would.

If you get an EFR be prepared to be sideways. In fourth. In the dry.

This sentence alone, should be enough to convince anyone to buy an EFR.
