325ic Calypso Euro Conversion - Houndstooth & dbilas now, MT1 & MM 3.2 stroker coming

[doorman]

Summer is short as you know bud!!

Hopefully you'll be ready.

Looking good so far.

picked up a spare m20 airbox and modified it for the m30 AFM. Wasn't difficult since the AFM inlet is the same width, just taller. Reused 2 of the holes, extended the opening in the upper airbox piece, and drilled 2 new holes.


Was also able to keep the air horn / velocity stack by cutting down the center to separate top and bottom. I then trial fit the 2 halves with duct tape (!) and they fit fine - full air flow from a larger cross section. So I filled the gap and JB welded the assembly.

new tune arrived - thanks Jesse! return chip getting posted tomorrow.
well played on the packaging btw.

Some good info here - 2008! Does anyone really do this old school stuff anymore lol.

Just don't want to take on a bigger tuning project right now. Alot of changes coming, so 1 step at a time - this is it for the season hopefully.

and e30tech has plenty of reading.
stock airbox vs cone filter dyno test http://www.e30tech.com/forum/showthread.php?t=23927

what dmcl is describes here is what I have in mind, but I need another m20 airbox to hack up first. don't want to mess with my original one.

similar m30afm in m20 airbox meme: http://www.e30tech.com/forum/showthread.php?t=14419

as is frequently the case, stock design is pretty darn good. hard to beat without a complete cold air setup. also was of the mind that cone filters don't flow as well but that's a generalization so... no data means it's just an opinion.

Those are some amazing headers!!!

drool is right Dan.. incredible to look at. def hoping I get the chance to own a set.. maybe even an RD valvecover too.

received @blackjack7s' AFM and sssquid chip today. will be shipping the chip back to sssquid as I have a 173 tune coming from them tomorrow.

you can see how much bigger they are in the pics below. they're not compatible with the m20 airbox either. I'm sure the E30/BMW vets around here know this cold... but the M30 airbox conversion stuff is new to me, and as usual the OEM+ thing always kicks in..

the M30 AFM was fully refurbed by Bav Resto last year and looks great.

the M20 airbox. M30 AFM won't bolt up, and the opening's too small



M20 vs M30 AFMs - use the same harness connector. M30 taller, same overall length and width
You see those nuts? That's how all our hardware looked new! zinc chromate plating in my future that's for sure.

Can really see the opening differences.

bolt patterns don't line up due to height difference (e.g., left to right in the pic doesn't line up, top to bottom in the pic does). even if they did the housing opening is too small for the M30 AFM

WANT.. Frank had 2 of the new Racing Dynamics long tube hearders left last year and I passed. I'm on the list for the next batch of 6.
Note his old dbilas plenum on the top of the pic :-)



re the inevitable midrange torque drop, i'm thinking the SC + MS combo will allow me to completely flatten and raise the torque curve. We'll see next year.

M30 TPS (6 wire connector, clicks at WOT).

per http://www.r3vlimited.com/board/showthread.php?t=347961, this is an automatic transmission TPS. apparently the manual M30 setup uses a 3 wire TPS, so I should be good with the M20 TPS I retrofitted.

@blackjackT7 had a rebuilt M30 AFM and an sssquid M30AFM/m20b25 tune. Unfortunately it was for a 153 DME but he made me a great deal. THANKS Jack!

I also went ahead and ordered a stage 1 M30 AFM flash upgrade from Jesse @ squid. He suggested I go with the mustang injectors so we're doing that. Also sticking to stage 1 and not stage 2 b/c I don't have the headers in yet. When the chip gets here I'll send it out for reflash and we should have something workable.

[bradnic]

Gonna try working with Jesse and the sssquid.com folks on this stage of the project.

I just cut the hoses for heater pipe back and rerouted the heater hoses to make it work. I never got any leaks and I never swaged the lip. I did fit some hose that was quite tight and double clamped it

sounds good digger. those hoses are all new so I'll try to find some used ones off one of the cars to hack up haha...

glad you stopped by man! I've had read way too many of your posts lol. I'll be reviewing everything again once I start the stroker phase of this project.

[bradnic]

Is that seriously the quality of the casting on runners 3&4?

Was it cast by a monkey using the local playground sandpit? Yikes, I would have expected better.

haha nah.. it's just an old part that oxidized over the years and was resprayed without proper prep. most of the paint has bubbled off there. I'll take it apart and sand blast the housings at some point, assuming I'm confident I can get it back together and align/tune everything properly.

besides that, cool project :)

thanks! Aussies and ITBs just go perfectly together. As soon as they RHD boys have a plenum ready I'll be taking a look :-)

haha indeed. just make sure you solve it before you get on the road right?

just snagged a rebuilt M30 AFM and an M20B25 tune for it. We'll see if it works. If not I'll put it back up for sale.

I love a good jig saw puzzle.
