facelift e30 M20b20 turbo

[e30_kid]

can't wait to see what you do with the car, i normally don't like odd from bumpers, but that actually looks pretty good

[e28forlife]

Wow, that is what I'd call a short shifter, lol. Is that not uncomfortable?
I really like the steering wheel, do you know what brand?

And that cabriolet is very sexy, you guys from Finland know how to put together clean e30s.

shifter is allmost perfect for me. i have to make new nylon-Bearing sleeve for shifting arm.

it´s not at all uncomfortable.:D
it´s race.:p

Steering wheel is L-tec http://www.ltec.nl/ltec/product/82 that kind wheel.

plus it got 60mm spacer "kit". and steering wheel is that deep to begin with that wheel is just about your chin. :p
no,i was just kidding,it´s really good position for me. and in race track it´s perfect position. :up:

and for streets is pretty good,alltought i would like to have power steering,but i can manage with this.
and these kind a car are turning corners at pumping gas.. :p

i bought new steering wheel yesterday (Raid hp) but well see witch steering wheel i´m put it in.

if i bought momos racing "buckets" at winter and make a roll-gage, i´m gonna drive with this wheel.

Thanks for your comment´s.
i was bit proud of that cabriolet´s look.:D
it was bit "shitty" when i bought it.
after few week cleaning and tuning with +OEM parts it start to look good.:-)

paint work turned out to be allmost like brand new after i polished it.

[anza(kla)]

at lunch break i took old turbo out of the car and start to take intake manifold too,but i didin´t have time to fight with that one ***king bolt,so i take it tomorrow off.

i sold old turbo today,and if everythings go right this time,i get new turbo this week.:bow:

and weekend i have to install turbo and weld exhaust outlet flange to downpipe and paint the car,etc..
if only i could buy even 1 hour more for this 24 hour :D

hope tomorrow i get intake manifold off,and take it to cleand up. it´s kind of like sand-blasting,but instead of sand they use very small glass ball´s.

i dont know do you have some kind a name this thing,so i try to explain it to you.:-)

tomorrow i get new (used) intake manifold and cylinder head cover. i´m gonna get these parts blast too.

today i ordered my parts-dealer few (s14) engine wire harnes´s
and new intake manifold gasget and few other smaller parts.

those (s14) part´s need to be ordered in sweden,and that´s why it takes couple days to come.
alltough intake manifold gasget they have "home" like they said it.:D
so,they promised part´s for me thursday. and these parts i have to install too at weekend.
i think it´s gonna be rush weekend. :D

next thing i´m gonna buy is a b25 throttle body. it´s much bigger than b20. if i remember correctly it was even 12mm bigger than b20`s body. i might be wrong also.
but still it is much bigger.

this kind a improvement today.

perhaps tomorrow more. :)

[anza(kla)]

yesterday didnt get much to do,because it was so rush day at work.

cylinder head cover and intake manifold came yesterday.
i sanded all marks off at cover and i think i´m gonnap polish it.:)

but that´s not the first thing to do at my project.:p

today i get hopefully those engine wiring harness´s
and i can put it places.

old turbo is shipped now. and i dont get new turbo until next week.

perhaps new boost controller and some silicone tubes gets here at this week.

today i might change those new injectors and put intake manifold on his place. well see how rush day is gonna be today at work.
this working is really taking out of time this building.:p

next week i´m think i´m gonna be on a vacation.
so i got time to build up this shit.:)

i take some pictures when i get something to do in engine bay.

[anza(kla)]

i have watched that allmost everybody here has changed 5x120 lug instead of 4x100 lug.

how do you changed it.?

this is how i thought about it:

i have take measurement´s about e28 rear-axle and found out that it would fit e30 with eccentric bushes and few small modifications.
so then you got 5-lug.
and + you could use 8-bolts (large lsd from e28) and e28 drive shaft witch is more stronger than e30 own drive shaft.
you could use also e28 lsd if you change typ 188 back cover,but still you cant use e28 drive shafts. i think that e28 got longer drive shafts than e30 got. well im not sure,but i would think like it.

if use e28 rear axle you got 5-lug rear and 4-lug front.

so then you have to change 4-lug front to 5-lug.

easier way would be just buy ///M-3 front spring struts.
but is kind of a rare parts in finland,and junk yards hasen´t got any M-3 for sale,caue if somebody see a ///M-3 e30 at junkyard,they buy it even if they dont need it.

and realoem says that front spring struts cost + 1900 dollars each.
so thats no an option.:D

somebody has changed also just e36 front wheel bearing and modificate it on e30 spring strut.

so perhaps the cheapest way would be an e28 rear axle and e36 front wheel bearing.

i think it´s not the easiest way,so please tell me how you were done on your on 4-lug to 5-lug.

[anza(kla)]

i have thought about this 5-lug modification again.

and made that conclusion that track is gonna change radically if i use that e28 rear-axle. so i have to get high ET wheels. and perhaps even 8.5x17" with ET 40 it wouldnt fit at original fenders. and thats gonna be a big problem. what kind of ET´s you got on your 5-lug wheels at e30.?
and tell me how you have done this 4-lug to 5-lug.

today i take intake manifold off and tomorrow i take it to blasting and i also take cylinder head cover to blast too.

i bought new fuel rail and install new injectors to it.
i put one photo of this fuel rail.

i had to take transverse bar off also that i got these S14 engine wiring harnesses at their own places.

tomorrow i put blasted cylinder head cover and manifold on their places and then i can put transverse bar in too.

engine bay is much prettyer now that what it used to be.
here´s one picture at this point engine bay.
there is still lots and lots of work to make it smooth and clean.
i also put one picture where you can see what kind of cable mess it was used to be at battery place.

battery place is bit "skin rust" so i have to clean it up really good and put acid-paint and then primer and then just basic black paint. and brake servo unit needs paint and cleaning too.

but i think it´s gonna pretty smooth at the end.
tomorrow at lunch break i think im gonna paint battery place and brake servo unit too. then i have to put wide-band lambdas cable also behind those harnesses. so after that only cables witch are showing anymore are just injection cables,water temp. cable to megasquirt and water temp gauges cable.

notice last pictures "diagnostic-plug" clever use.:giggle:
m20 diagnostic-plug is intake manifolds other end. so i have to get that hole fitted with something. and then i realised it. "why i wont put fuel pressure gauge to it.?" and there it is now.:p

hope i get engine bay kind of ready (instead new turbo) at this weekend.

perhaps tomorrow more pictures and story.

hope even someone is interested to read all this shit i´m writing about.:)

Typically I believe E36 parts are used, I don't believe they need to be from the M3 as all E36 are 5 lug. The downside to using these parts vs. E30 M3 are the high offset wheels.

And thanks for sharing, I enjoy reading on your progress.

There is a whole sub-forum dedicated to the 5 lug swap.

Nice cars. You really think you can hit 380whp with the turbo b20? That seems a bit of a stretch. But I wish you luck and would love to see the results!!! Turbo m20's are nasty!

i ment those ///M-3 parts was from e30 M-3.
sorry,i didin´t make myself clear enought.:???:

I was speaking with my friend with this case of changing 5-lug.
and he throw a wild idea for it.
it´s kind of clever idea. and i´m feeling myself bit stupid how i didin´t think this at myself.:???:
well one man cant realise everything,no matter how simple is that idea.:D

friend´s idea was so easy. "why dont we buy new wheel bearing´s and fill those 4 (wheel)bolts by welding and just make new 5 bolt system by drilling 5 holes and make new swirl´s for it.

here are only one thing to measure
"How big is e30 Wheel bearing´s "plate" ?"

so is it safe to drill new holes,or would holes come too close at "lip" so in stress edge of plate is gonna crack.

so i have to do some measuring at wheel bearing and if there is gonna be "safe-zone" to the lip,we are gonna try to drill 5-lug at e30 bearings. welding and all other mechanical work is not a problem.
if this is gonna work,i could use e34 wheels,and here in finland all pretty wheels has been at e34,so it would be better than fantastic if i could use low ET rims on my car.:D

love to share my project.
even better if somebody might get some "kick" to work on their own car. :)

Nice cars. You really think you can hit 380whp with the turbo b20? That seems a bit of a stretch. But I wish you luck and would love to see the results!!! Turbo m20's are nasty!

thank´s for the link.
i appreciate it.:D

sorry,im not good explaining things.
i ment 380hp with engine.:D
my english "slang-vocabulary" isin´t so good.:???:

but if it would be 380hp at wheel,what that be at engine.? 410hp perhaps?

i think 400hp is not really a problem at b20.
i think it can be done. it might take time and money,but i think it´s possible.

my first goal is to get car running good,and then 350hp?
"hunger get´s bigger while you´r eating" :D

well see how much boost this 2mm mass gasget is gonna take before blowing.:D

at winter i start to build up new engine.

i allways wanted to know how much you can get out of b20 engine. so perhaps this is the engine witch i build up at winter.:)
everybody in finland is building up b25 with turbo,without turbo big hp´s b25 (stroke-kit,etc..),and so on..
nobody is´nt building b20.
dont know why.
so it makes me different kind of young man. :P

here´s little list of parts i have to buy if i decide build up b20.

-"roll cam shaft" ,or custom made cam shaft
-custom made pistons (comp ratio need´s to get lower than is now (8.5:1),otherwise it´s not gonna last high boost´s)
-crankshaft connectin rod
-some good head gasget (not cometec,copper or mass gasget´s anymore for me)
-new bearing everywhere

etc...

well,will see at winter what do we do.

and when i get it run at dyno,you can be sure that i show dyno papers here,so dont worry.:D

[JGood]

"hunger get´s bigger while you´r eating" :D

hahaha, I like that!

I didn't realize you were building a motor. I thought your were trying to take a mostly stock b20 and just slap a big turbo on it and hope for 380hp.

Your goal now sounds more realistic. Good luck! I really like your old cabbie, and this car is pretty damn nice as well!

well it is so.:-D everything get used to.;)

as a matter of a fact i´m not right now building engine,because it´s been "build" 7 months ago. pistons are turn in a lathe and take off 1.3mm of the head,and whole block has new bearings and all new pistons rings is new.
so now i put that new holset on,and well see how much we can get out of allmost "stock" b20 engine,with big turbo and big injectors and adjustable engine management.

in winter im gonna build up perhaps this motor. or b25,or even b34.;)
well see what its gonna be.

New engine size is depending on how much we can get out this b20 with these modification´s
if 350hp is in the "limit" at break,i think i just build up bigger engine.

everything depends on everything for now.

You obviosly are hanging out too much with Maza (know as mv044 in this forum) :D

[anza(kla)]

yes,and hednam,and also other e30 builder´s in finland.:D

hednam has bought maza´s old project body and now he´s searching a b34 engine for it. and matti got´s S38 motor,and also that b25 in ix,so i have thougt how about if i stay this b20 engine,and not to be like everybody else.

well,it´s kind of a open still about that motor thing for winter.

i havent have done anything for the car at weekend. been so busy doing other things,and helping my friends,and so on. next week im on a vacation and hopefully i gat those valve cover and manifold to blasting. and then i can put those parts on theirs own places.
battery"place" is now rust free,and i put acid-paint and then primer for it and let it dry for weekend and tomorrow when i wake up i go to my work and paint it black. i cleaned brake servo unit up and painted it satin-black,it´s not like new part,because it´s got to be removed if i like to do it "like-new". well,in winter this is gonna happen too.;)
