Sam's Proper MX-3 - LT Turbo project *Parting out*
-
Sam, do you have a BOV to use?
encase you do not I have a stock OE BOV off of a Ford Probe I can give you, just PayPal me shipping.
I used it on my B6 for years and was perfect. it is 2" diameter pipe I believe and it is a recirculating, but it always had a nice pffuushsh kind of sound. Let me know :)
-
No don't got one yet, was thinking full atmos. just for a laugh to begin with then recirc. when I wanted to be a bit more stealth.
Im interested thanks could you post some pics.

Bar a little bit of a surface grind to the flanges the IHI to T25 adaptor block is complete :D
Final height is 38mm
Other good news! won what the Fella reckons is a recently refurb. Garrett T25 (new bearing, seals and wheels) for 75 quid on Sunday night, looks a bit ropey on the outside so will clean it up when it arrives and sort out new water/oil ports for it, and also "clock" it by rotating the housing's to get the oil drain right and the bottom and the turbine housing pointing somewhere nearer to the intercooler :D
-
75 quid? Nice job! Good to see progress on the turbo part of this project. Have ya figured out how to wire up the AEM piggyback?
-
Yep worked out to be 97 pounds delivered (My keyboard is all fuct up wont let me do the pound sign)
Aye we know how to wire it up its just a case of finding the right wires now, as no wiring diagrams exist for my car not even on autodata! will mean a day or two with the multimeter out in the car. I got to help my wiring man fit some coilovers to His Ibiza cupra then we should be on it.
-
Sam a thought on when you wire your piggyback up. rather than wire up the piggy back to the Throttle Body for values, one thing that tends to work better is to wire in an RX7 MAP sensor and run your piggy back off of the MAP. it give is a lot more adjustability, and functionality out of the system.
-
Thats a thought Josh, but the AEM FIC has a built in MAP sensor.

Well I guess you are good to go then :)
-
Yes the on baord MAP sensor is good for 27psi and they supply you with rubber capillary line and T piece to tap into the inlet manifold, although me being me will change it for silicon line with a hard plastic over-pipe to go through the bulkhead and some nice black Y pieces as I didn't like the nylon coloured they supplied.

Been a busy few lunch breaks this week trying to repair the broken stud and crack on the exhaust manifold. The old stud was hard as fuck to drill through!
Ground out the crack to a V and has been TIG'd using stainless steel wire, in hindsight should of really preheated as a few more cracks appeared in the weld, have no idea if this is going to work or not and dont know a way to test it. Might have to grind some more off and try again next week, if that dont work I'll be hunting for another..
-
With the imminent arrival of the new tubby thought I better make a start at looking at the downpipe fabrication. Have decided to try and use these 2.5" stainless steel mandrel bends as that's what I had a few of anyway so got a couple more, and have found this great pocketed flange for a T25 from the US milled to take 2.5" pipe. While Im making this will also try and cobble together a decat pipe section aswell.
Gives a better idea of the shape I think needs creating..
-
Are you going to go 2.5" the whole way back from the downpipe, Sam?
-
No I figure for ground clearance and noise reason I'm going to taper it down to a full 2.25" system eventually.
-
New Turbo arrived yesterday so I quickly stripped off the exhaust elbow to check for any cracks this time, absolutely none and zero shaft play either. It needs clocking, but I have to buy some seriously good circlip pliers first! Also came with a Turbo Technics emblem on the wastegate actuator(might of been rebuilt there or an actual TT actuator?) and an oil drain that I can probably modify and shorten to suit.
Also spent a few hours yesterday with the multimeter and some long reach probes checking a few of the wires on the
the ECU plug for the AEM, found around 75 percent of them so far, with them being colour coded and matching some
of the diagrams its making it fairly straight forward. We are going to hook a few up today and see if we can get them registering:D
Watch this space…
-
Looks like ya picked up a right bargain there! Glad to hear progress with the AEM is going well.
-
Yeah total bargain well happy! AEM is going great ta! its live and showing TPS, MAF, RPM, battery voltage & crank & cam on the laptop, just the injectors, O2 and MAP to go and we are done.
-
Sweet! Awesome stuff, Sam!
-
Cheers Jay I cant take all the credit for it though my homes Peter N Younger certainly knows His way round a wiring diagram or three 8)
007 (psi) license to turbo & kill clutches…
-
brilliant work! Hope you've got notes of everything. Is it actually running the car now then? Fuel / spark?
-
Cheers Marc! Yeah got oodles of notes that I need to make into a nice XL document or something. It was actually a nice enjoyable wiring day, usually having worked on French cars there a complete 'mare wiring, but nearly all the wire colours matched the schematics so that was a massive help :D
It is fully running all the time now with ign. on but my understanding of it is that all the fuel/spark tables come set to 0 as default so without changing any of those it wont be affecting anything as such just yet> Just running in harmony with the stock ECU :D
