Mega Squirt Ordered!

[M5pilot]

Just got Ant to order it for me for stage1 of the turbo conversion.

Will run NA for a while as I collect some parts for the turbo conversion.

[e30_Turbo]

Good lad

[Jon_Bmw]

Good good another convert in the making, well done Mr pilot and doing it right first time by installing megasquirt N/A first. All these people getting megasquirt are making me very jealous.

Nice one Sal

I'm doing the same.
did you get MS-1 or MS-2 ?
do you intend to run ignition ?

I'm getting MS-2 shortly and I'm intending to completly get rid of motronic ecu, once i got ms2 going fuel and sparek then Holset hx35 going in,

!!!

TURBO B00000ST HERE I COME !

[M5pilot]

I think its MS2 im getting.

Will get spark at a later stage too.

[Jimbob]

Too many bloody pages on their website for me to understand anything about it, give it time and I might actually get some of this ordered!

Good good i'm not the only one, phew. Have you found a suitable turbo yet for the beast?

[Toby_Unna]

well i don't know much about turbos really.

Alex suggested the T04B on this site at $399 new
http://turbocalculator.com/sale-garrett.php

but there's several options for that turbo listed and i don't know what they mean to be perfectly honest. better do some research. although if someone pointed and said That One then i'd just order it.

and i found a T04 turbo flange on ebay US for something like $30 buy now, but haven't bought it yet. I guess the turbo and a flange would be a good start, then I'm going to find myself an E28 M535i manifold to mount upside down, I think that gives the exits in the best position (they're right next to each other at one end of the manifold). then try to mate the flange and manifold together.

tried my alpina 6-branch on a spare 3.5 head upside down and if the ports don't match perfectly then they're close, which is nice!

spent the morning in a local breaker trying to make a huge intercooler from one of those old volvo four pot turbo saloons fit an e30 front mask, but gave up. it would pretty much go in but the inlet/exit pipe stubs would need metal cutting away where you really shoudn't!!

i'm thinking i'll get the hardware installed and try to run it with motronic and a rising rate pres reg to start with, then convert to megasquirt when i have the money...

[e30_Turbo]

Manifold, flanges (turbo and exhaust), charge pipes, down pipes, the rest, as a great man says "is nuts and bolts".

Toby, you need to check the compressor maps out, make sure the turbo makes it's peak effeciency in the flow range the M30 has.

I think Alex (turbobrown) has a very good grasp of all things theorectical (sp), he may be able to help you work out the facts and figures you need.

I also saw some rather tasty audi RS6 and RS4 intercoolers on ebay, HUGE diameter in/outs and very tasty too, should fit under front valance, one in front of each wheel!!

[Ant]

Toby the 740/760 intercooler will fit without chopping the X member away, Thats exactly what IC I have mounted in mine, yours can be doine easier too as you have the Tech 2 valence so you could chop the original steel one out behind that M8

For all the Megasquirt wannabees, use the Ms1 unit, the V2.2 PCB ( NOT V3) get your head around the fuel only side first , then add the HEI module ( $75) and play with spark using the MSnS-E code version.

I have a stock M20 basemap for spark now, I pulled it from the moronic( no typo ) and input it into the Ms constants section

Be aware the software is a can of worms, but will suddenly make sense once you have the engine idling and view all the maps in real time, Emerald etc are the same from what I can glean

If anyone needs a hand with any of the MS stuff I'm happy to muck in where I can , Fozz is on the case too peeps, he'll explain better than me, to much tech babble this end I fear

As for the Wideband , well you only really need that for tuning from scrtach, the plan is we'll use the community WB02( cheers Mark ) to create the full N/A basemap on Sals touring , thats 95% of the hassles sorted fellas, watch this space

[Jimbob]

Call you tomoz ant if that's alright dude..

[Toby_Unna]

Ant, can't remember the model name of the two volvos I found, but 740 760 sounds about right.

i'm sure those that I found won't fit though, it wasn't fouling the crossmember but the in/out pipe stubs seemed too far apart for the mask and it looked like i'd have to hack into the welded-in uprights at each side of the mask. Or do i just have to stop pansying about and get the grinder out (not usually a problem!)

the two volvos were very similar and had similar turbo installations, but slightly different intercoolers. one with the in/out stubs half way up each side, and one with them at the top. i'll take a couple of pics when i go back and see if either looks the same as what you have installed.

just another quick q Ant (or anyone!)... i need to decide whether to get it running with motronic/rrfpr as Jon_bmw has done, or to go all out and put megasquirt on.

i know that megasquirt would be a far better option in the long term, but i want to start with the motronic setup to begin with. however i'm just wondering if i'll need a complete RR map for the mo-ronic ECU to get the fueling right and if this will ultimately lead to being pretty expensive anyway?

sorry to lazily ask questions without researching it much myself... but i only decided to do this a couple of days ago and now need to crack on ASAP as it's causing me sleeping problems!!!

[Ant]

I have the volvo unit mounted upside down Toby, the stubs are tucked behind the iS lip , I had to slightly clearance the inner front lower X member but nothing that affects structural strength.

As for the RRFPR, cheap and cost effective M8, I'd advise a unit where you can select the rising rate though, most are 10:1, be nice to be able to come down on fuel if its mega rich.

Standalone makes it easier long term, but will require more patience.

HTH

[Toby_Unna]

so the RRFPR wil fuel it correctly (ish) when on boost without touching the motronic fueling map?

if so, cool.

Ant, sorry to pester you about volvo intercoolers! But does yours have the pipe stubs at the top and compact rounded edges to the unit, or stubs half way up and chunky square edges?

as i'm going back to that breaker ASAP! there's a stripped e30 with 2 volvo intercoolers piled on the back seat and i don't want anyone else getting any ideas so I'll just buy it... I did wonder about putting it in upside down with the stubs facing forwards, but was a little short of time yesterday

[Jon_Bmw]

The only problem i can see at the moment is toby that you will need to change for bigger injectors i think. I'm on m30b35 ones on an m20 so i would have thought you would need to get some larger injectors or the rrfpr just won't cut it. This of course makes it fairly lumpy at idle and very rich at first start up as the ecu wants to bung more fuel through. Once its got through the first 3 mins of idling mine actually settles to a fairly un-rich level. Back to those injectors, 840 or 850 ones possibly?? You'll have to check whether they fit as i've no idea.

I can't help you on the intercooler front if you need to get it quickly by the sounds of it. Buy both if they are a tenner each and you'll probably make money by selling the one you don't need on ebay as nissan 200sx upgrades.

Toby a good place to look for info is http://www.e30tech.com and once you've signed up i've even created a topic on your behalf http://www.e30tech.com/forum/viewtopic. ... 197#148197

Its probably best if you can give them some more info on what your expected gains/targets are etc.

[Toby_Unna]

Jon, cheers for that, I'd actually already seen it in the FI links section and am registered. I'd posted a reply to something Mark wrote there a few days ago, and have replied to your thread

[Ant]

Toby

mine is the bigger unit with the 2.5 inch stubs, they came out either side of the Volvo rad @ the top, I have reversed it so they now face backwards at the bottom, I knew I should have taken some pix ! sorry dude I aint taking it out again


850 T5 IC would fit nice too if you can find one.

edit:

found a pic from fleabay, this is my unit...................

[Toby_Unna]

fab thanks Ant
that does look like one of those I was looking at. better go buy it!

[buster]

Ive still got my turbo kit for a m20 if anyones interested.Everything but management and fuel regulator.

[Ant]

Andy.

PM me with regards to that kit please M8

[buster]

Ant,did you get my PM ??
the zone is all screwed up at the mo,not getting e-mails for new posts or it seems PM's arent going through also !!
