    Sure no problem, make sure you get the latest wari and firmware.

    Manifold is in production, Adaptronic arrived (I have to get new connectors and finish the loom, and as it seems it does not work with my macbook, so I have to dig out my old laptop), I got a new subframe and went to Renault to buy new bolts and the rubber mounts (only the rear ones are available, so I was very lucky having 2 new fronts in my stock). I'm thinking of welding the subframe to make it stronger and weld some beefier plates to the places were the engine and gearbox mounts will be wrenched to the subframe.

    These rams head manifolds are great, through Dave?
    Personally I think the engine mounts aren't too bad, the gearbox ones aren't up to much. I'm working on some, to make a batch, but will probably be next month as if got carried away with other bits on the never ending project!

    From FBI Motors mate. Good value for money.

    I'll update in a week or so, work is hindering progress :(
    Might have to invest, nice looking bit of kit, next year though, I've got enough 'bits' to play with for now

    Exhaust manifold is from FBI motors in France. I have their very simple model (not equal length) on my other engine, but Jo and Henk think that the OE one flows better...
    I thought about reinforcing the engine and gearbox mounts, because i've heard of some subframes who cracked where the mounts are bolt on... (in France)

    Any pics of the other one? Interested to see why it flows worse. I never expect tubular manifolds to increase power unless going for every last bhp and it's designed to do so. With that, equal is obviously what you want but I'd prefer wildly un equal for burble.
    Has the subframe cracked for a few people? Could it just be using the wrong nuts without washed causing extra stress?

    The subframes crack due to careless refitting of the engine/engine mounts. The studs (on the bottom of the mounts) that drop through the holes in the subframe can catch the reinforcing plates that are spot welded to the underside of the hole, and breaks them off. Once these are damaged or missing it's only a matter of time before the engine rips a hole in the subframe.
    I have never seen one damage the subframe with the reinforcing plates still in place and intact.
    When refitting the engine you need to engage the primary shaft, pull the bellhousing and engine together with a couple of bolts, then lower the engine slowly and make sure you locate the engine mount studs in the holes, as the lump goes down and the studs go through the holes give the mounts a wiggle every 5mm or so and make sure they havent gone tight and the threads aren't grating on the reinforcing plate.

    Before you refit an engine, get a small grinder with a flap disc on it, and chamfer a 1 to 2mm, 45° angle on the front of the primary shaft nose. This makes it an absolutely ridiculous amount easier to locate and engage the primary shaft in the clutch splines. I've been doing this for many years now, it makes such a difference.

    Nice bits. Are these stocked items or made to order with a minimum amount?
    Liking the position of the turbo on the second to last picture but yours does look fancier. Inlet runners a good starting point too.

    Made to order, pay in advance. But I got it within 3 weeks.

    Yep I had mine within a month and it was a 12v and I sent him my wastegate flange to include too.

    Mine took 2 weeks from ordering to arriving. Ive got the rams head type with EGT port and NO ext w/g take off.

    What's the prices? Any idea for other items?
     
  17. DaveL485

    DaveL485 Staff Member

    Ranges from about £260 for a standard replacement all the way up to my 12v ext.wg rams head which worked out to about £380.

    I'll get you his contact info over if you want, PM me.

    Today I did a quick ride with a nearly original 21T, as I want MOT for another 2 years and put everything back OE over the winter.
    It still felt faster than original, so i put back the boost to about 0.8 bar and it was a bit tamed. Now I have to go to RR to prove that it is not to powerful;-) I'm allowed to have 193bhp max. What a joke with MOT here...

    Nevertheless it was great to be out with the 21 after a while and I just hope to have gathered enough paperwork and certificates to satisfy the MOT guys...

    RR today, my BHP-Feeling is not to bad;-) As I tried to set the boost to have OE power, resulting in 185bhp. The Dyno Print out should be ok for MOT.

    new MOT on this, after putting it nearly OE and having some certificates done for the wheels, wheel spacers, strut braces and other non- OE parts...
    Time to get the Boost up again, fit the FMIC, and Brembos;-)
