Funny how i was thinking about a 1jzge to E30 swap a couple days, but as soon as i though of the sump and vvti, gave up on the idea. not that i have a e30 or anything like that anyway.

why? is that bad thing?

yeah, with the exhaust. i wanted to get twin pipes out the rear, but that would be really difficult - ill find a way!!

my mate has the 2.5L in an E30 -- soon to go turbo, motor has just been rebuilt due to huge Cam wear! goes alright with just the 2.5L bottom end - 2.3L head and Lotus forged pistons! wierd combo but when the turbo goes on should be quick!  only thing with these cars is lack of room down the car for exhausts.. 3inch would scrape out big time!

only thing to watch that i know of with these things is the rubber mount from gear box to tail shaft!

that will be rad!!

thanks for the tip on the "mount from gear box to tail shaft" ill look in to that.

Theres an RB20DET powered E30 323i here in canberra, been that way for a while too.  Aparently the hardest part is the engine mounts

It was featured in a magazine but i can't remember which one

Ahh yes, that car was in Zoom had an RB20 in it.

that will be rad!!

yeah it's just that they are solid rubber and do crack.. if they crack apart the tail shaft will go flying (mates had a big gash in the tunnel from it happening), can source these with steel reinforcement within the rubber for better strength! it's like a uni joint! might be a good idea if still using these to run a U support like race cars use to stop it dropping and digging into the ground!

thanks everyone for all the response!!

and thanks for the links.

with the mounts... i had problems with the solid rubber engine mounts (probably just age) but i will defionitly look at getting them upgraded - thanks

shite.... a e36 m3 in a e30. that would hammer, probably a bit pricy for me though

I think you should look at custom engine mounts, as I broke two (can't remember which side, but was the same) engine mounts, both were less than 2 years old. It is the torque of the bigger motor they can't cope with :(

which part of the mount broke? i have seen 2 E30 323i brake the mount from the cross member on just standard power.

you could get the 2.5L block from the 325e.. which are cheapish, then put the 323i head on it and rebuild.. still 2.5L and they do go hard!

i actually thought about that couple months ago.... would be a good idea, then get it turbo'd later, he he

sorry to hear about your mates bimmer blowing the diff and screwing the tailshaft, i will have to get a better diff though, its got the stock one (non LSD) dont know the specs, but ill definitly upgrade....

thanks for the advice Ronin 09,

yeah he's saving up for a turbo for it atm, but with this little set back it may be a while! have you got any ideas where to get a lsd for the E30?

was gonna get an M3 diff but it'll take our suppliers about 3 months to get it from germany so we cant really wait that long!

email this guy, [email protected] , its a european parts place in melbourne, they have helped me out a fair bit, not to pricy. dont know, they will probably have to order it in aswell though, other than that cant help you sorry.

unless you try and get in contact with the NSW bmw club, they might be able to help you out

I had three factory LSDs in mine -

factory 3.45 'small (housing)' diff - early E30s had this

3.7X 'big' diff

3.9X 'big' diff

There are a heap of LSDs that fit from various 3 and 5 series, I have a mag that lists all the ratios back at home in Melb (I'm in perth) that lists the ratio and car they're from. The E28 5 series shares the same diffs.

Hope that helps

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
