take a look at this, this guys knows A LOT about the m54 swap. both with OBD1 and with megasquirt.

hope that helps, cheers.

if you want to save some money, buy a cheap blow off, but not a cheap wastegate.

if the BOV fails, the turbine wont like it much, but it wont kill your engine. if the wastegate fails, it can be pretty nasty.

well with a turbo you are using waste power to drive the compressor, while the supercharger steals power from the engine. it does have its benefits, but i guess a correct turbo setup ends up being a better choice.

plus personally ... i hate the way chargers whine.

emissions and economy is the reason they run it so hot ... not a good deal on the long therm.

i will try to get a 80c thermostat, that should help in summer.

ross, yeah regarding the head bolts, i read that its a weak point on the M52s. they recommended to use arp studs instead of bolts. aside from that, as redcar said, the other items you mention are just risks present in all boosted cars, alloy or not. one thing i saw regarding M52TUs and i believe it ...

been reading e46 forums, it would seem that the M52TU and M54 head/block are almost indentical, so using that as a reference 500-600hp has been done. Thats good enough for me, not planning on going further than that.

Yeah i did know the ratios where similar, but i sold it to cover the expenses of the new box.

Anyhow once i put the turbo on that m52, power should still be too much for the smaller box of the 320i.

Sold it to a friend who had an E21 with a 4gear box.

Cheers.

As you already have a 3.15 diff you would be much better off using the 328i manual box and prop Actually i prefer the longer ratios, since this will eventually be boosted and that way i can use the beefier torque of the engine. The engined ended up being a M52TUB28 from an E46 328i, so if i manage ...

Hi guys, do you guys have some info on how much power the alloy blocks will hold? Lots of people say they wont hold much power, due to being alloy blocks, but couldnt find any case where the block failed to excesive power. im aiming for 450-550hp on a M52TUB28 with forged pistons and rods. i want to...

Hi guys, i got for this project a M52 from a 328i e36, a G260 from a 325e, and a 3,15 diff from a 323ti. My car is a 320i 84, ive kept from the M20 the flywheel, starter and propshaft. does anyone know if the propshaft from the 320i will work with the G260? i havent had time to fit the diff yet, wil...

Hi guys, anyone knows whats the flow rate of the original oil pump on the m52?

im building a dry sump setup, and i need to know what requirements i have for the high pressure stage of the pump.

thanks for your help.

nice throttle body core

3.23 compact diff should fit,but will not last as it is small case diff,best bet is 3.15 from e28 524td or 3.25 from e34 524td 323ti diff is a mid case, ive got a 3.15 LSD from a 99 323ti. E36 diffs don't fit. Either an E30 M3 diff, which is often a 3.25 ratio or I believe a Z3 2.8 diff goes in and...

As long as you keep the original flow direction, position wont be an issue. Keep in mind that having injectors, fuel rails, and piping on the bottom, although nice looking, will be a PITA to work if you need to tinker with that ... But regarding functionality itself ... none of the parts depend on g...

wow you already started playing with the furnace? cool.

any close ups on the pieces you casted?

so carbon fiber wasnt good enough, now you need to start casting your own metal stuff?

dont know if you are familiar with this forum, really lots of usefull info. great read.

hope it helps, will keep on waiting for new updates, cheers.

after a fast google search, the cars with L-Jet with lambda sensors actually had a version called LU-Jetronic.

so i dont think you can add the lambda sensor to a regular L-Jet.

i have a 1983 m20b20, and i can tell you the wall thickness is 6mm on the 80mm cylincers. so boring it up to 84 till put that wall on 4mm

http://www.e30zone.net/e30zonewiki/index.php/Building_a_2.8 There you go. Regarding the turbo, im doing a M20B28 turbo myself, i got a MS1 for engine management. 42lb injectors. boost controller and wasted spark from the MS1. Cant advise you on any specific turbine, since i will be doing a twin turb...

yeah my logic behind this is that on 84mm blocks, people say its safe to overbore them up to 86mm. And given that cylinder center distance on M20s is 90mm, if you overbore to 86mm, you cant have more than 4mm of wall thickness there. Then if thats the case, and with 4mm walls you are ok, i can go fo...

plus i believe 135mm rods are lighter, specially if you go for the M52 ones if i recall.

its ilegal to import used engine blocks

and even if you get it here, you cant get it on the car registry (yes, chasis number and engine block number are part of the car registry).

so im basically stuck with this block, given that, i would like to see how far i can pull it before i screw it up.

if you are going for custom pistons, why are you using the 130mm rods?

im going for a 2.8 build myself (boosted), but i will be using some 135mm eagle rods, to try to keep a nice rod/stroke ratio.

Cheers.

Not a cheap option to change the engine down here, actually i will be spending almost 4000usd on the M20 and thats the cheap option

I must figure out how much overbore i can pull out.

Hey guys, im trying to figure out whats the largest overbore i can have on my block. My car is a 1984 320i, but the block was casted in 1983. I measured the wall thickness through the water pump hole, and it measured 6mm. If someone has a 325i/325e block laying around, could you please do the same m...

2 weeks and no updates?? ... come on Alex!!

Its easy to start throwing out really large numbers, but its hard to relate that to car performance if this is your first turbo build. Is this just me, or it happens to anyone else? Yap, so it's better to start off with 300-400hp, because after couple of months you'll be wanting more. Then it's muc...

Thats one of the best arguments for a reallity check ive ever seen :D Its easy to start throwing out really large numbers, but its hard to relate that to car performance if this is your first turbo build. I have set up my "HP roof" at 400hp (lets call it 320-350whp), but some days i start dreaming o...

dude, that is just plain sick. alex, you are the man!

appreciate it dan.

baptie, dont you notice an increase in low end torque (and in consecuence a reduced spool up time)??

my understanding was that by reducing overlap it helped with low end torque too.

regards

this will be a boosted car, so i guess when to turn it on or off will be part of the tuning process.

but knowing at which rpms the original setting works is a good start point.

regards.

Hi guys, is anyone here running a M50TU or M52, with a megasquirt and is using the intake vanos? AFAIK this engines use the VANOS as an on-off, not a variable position as in later engines. Ive been told i could use the nitrous output to control de VANOS, so if you did it this way, i would love to he...

Yes sir, appreciate it

now i just need the intake ones

Electronics AFAIK are a PITA.

I know of a few m54 swaps, most either use stand alone or OBD1 conversion, i believe i saw one with the original engine management but that was an extremely complex and high tech adaptation. The guy was an electronics engineer if im not mistaken.

Regards.
