Grab hold of the engine and give it a good shake. Can you see excessive movement or knocking from the manifold on the subframe?

Mine will be up shortly. Last track day next weekend then it's coming off. 2 lambda port one too so will suit ph1 and 2.

Are you sure 94db? There was one at a track day I was at and sounded way louder than that. It was louder than my Decat yozza system by some margin. This was at knockhill who don't really care about noise levels so it was ok but some other tracks are just kill joys. Where is your track day?

Sounds similar to imprezas to be honest. They use MAF sensors and tend to have fueling issues with atmospheric dump valves. As MAF sensor has already calculated how much air has passed the sensor, if this is then dumped the ecu has already calculated how much fuel has to be added and so causes...

Pre-detention is caused by inlet temps being too high and fuel combusting under pressure much like a diesel engine and is not the same as fueling issues. Pre-det causes pistons to be forced down when they are trying to come up and vice versa and is a cause of engine failure by bearing failure...

The bigger turbo will flow far more air. Pressure is about resistance not flow. The smaller turbo will reach a level of power where it will not be able to supply enough air to the engine but will spool faster than a large turbo that will flow enough air to feed the higher power level but will...

Do they only work with MAF sensors rather than MAP's.

Does GEN90 ecu's use only OE sensors or do you need to add or change any for a turbo setup?

Someone was selling one on the Impreza p1 forum I'm on and just got thinking. Cheers for the input though. I had only heard of them used on hondas and Subaru's but I don't stay too far from Andy Forrest who is a bit of a dab hand at these. Out of curiosity, what ecu would you recommend for...

Anyone know if these are any good for a turbo 172 for boost control and would it even work with an OE ecu? Cheers

Renault?

Are they seized or you can get hold of them to remove the nut? This was a complete pain in the ass when I did mine. Up there with fitting inner ARB Bushes. Big hands + Renaults = :mad:

Cheers for that mate! Will do with the turbo actuator. Running rich would be safer than running lean, just cost more in fuel. I will speak to RSTuning and see what they say about the std ecu side of thing. Owen:s ran his turbo setup with a RSTuning remap on his std ecu with no issues that I...

Ok, cheers for that!

Would I just send him my ecu for the base map?

Yeah, I am using mineral oil and will give a gentle thrash now and then.

Could I? I was going to put a filter over the turbo inlet to make sure there was nothing sucked in. Would that be enough?

I was thinking of bypassing the turbo for running in by putting a filter on the inlet manifold so making it N/A until run in. I will be getting a full map when my new ecu is set up.

I know you do for the f4r engines (172/182) so I would presume you would for these. If there are no timing markings then you will and you would be as well doing the timing belt too as it will need to come off anyway. I'm sure someone will be along soon to confirm.

Ha, think I might sh*t myself every time I put my foot down. What would you recommend for the running in?

Get yourself a haynes manual and read up on before going on. Should be straight forward I would think. Oh, and how do you know the head gasket has gone. What are your symptoms? Have you done a compression check?

Got a new engine that needs run in and want to check before fu*king it up. It's a turbo setup so low comp pistons and different manifolds and injectors to standard. I have an adaptronic ecu to use when the full map is done but for running in purposes would it be possible to use my original 172...

Did that sound like a welsh thing to do? :rasp:

Going to EFI-parts as it is the adaptronic ecu I have and they are one of the few if only place in the UK that can map it. They are down in Cheshire though. I had considered Performance HQ and spoke to Russ Paton who said he should be able to map it but I need a custom loom too that is...

Looking good mate. Loving the RS! Do you know where you are getting it mapped yet and are you going aftermarket on the ecu?

Check the brake fluid level.

Ah i see, makes sense now.

Just to confirm from the helix website. Is the organic part no. 605116 and will it cope with being used on a turbo setup? http://www.helix-autosport.com/performance-clutches/renault/

Thanks pal, I'll look into that.

Cheers mate, that would be great!
