nice one on the turbo

[djivesp]

Hey guys, thanks

Mongo - that's a bloody good idea and I'm pretty pissed I didnt think of that at the time!!
I'd imagine it would be super precise, I don't know if the ride would be maybe a bit too harsh though? As that is the only bush in the whole corner!

I'm not sure about how you're orientating the Z axis looking at the photo - but the lollypop bush holder can slide towards and away from the gearbox - giving more/less wheelbase and castor at the same time. Course a nice big rose joint would have achieved the same thing with much less complicatedness!

Very little progress lately as I got to hammer a gallardo for a couple of laps on a experience day last weekend (I SWEAR the kadett was quicker lmao), and been waiting for the prop, patching bits of rust here and there, pics soon

Love the shifter a page back. Awesome build this.

Are you running an oil cooler on the rack set up? As every rack upgrade I look at for e30's I kept finding people had to put bigger coolers in as it kept getting hot.

But looks awesome as usual!

Cheers benn
Gary - that's in interesting point! I wasn't planning on doing that, I'm thinking that the pump won't be on permanently, only when round town etc, so should be ok!?

[Gary_808]

Oh are you running an electric pump? Probably won't be an issue then, I think when it gets hot it just gets heavy, and if you won't have it on any way it won't make a difference lol!
Cause I'm looking at the route of blanking it all off and fitting epas column, but I'll see how you get on first.

Any updates dude???

[djivesp]

O HAI!
thanks for the bump corsakid, i totally forgot I havent updated this in over a month!
so happy new year to everyone, etc etc

I've done quite a bit on the old shlaggg, bits&bobs really and she now goes and stops all in a straight line and everything !

The engine bay and front all got a tidy up, including fresh metal around the headlights, various patches, new mounts for the intercooler, de-rusting here and there and then a paint with good old hammerite


Then some electrickery - new dash panel with neat distribution blocks, a ****loads of switches and even USB chargers built in :


Oh and carpet . Light tough stuff off ebay, should be nice.


Sorted the smoke situation hopefully, i think it was the blocked return. hooray!


Then reworked the turbo oil feed by deleting the gauge, did a bit of tidying on the relays and drivers (fan, boost controller, water injection), mounted the water injection gubbins in an electrical enclosure and mounted it in the bay and plumbed it in, also made a heat shield for the snail to keep the heat away from the shell. Got a new turbo oil feed aswell after the BSP fitting on the old one split from over-tightening it. Shiny and new and awesome for £12 from a local hydraulics shop .


now need to get the dash-pc sorted so I can start mapping. Fried the carputer mk2 when my hand slipped and nipped a tiny resistor on the motherboard :'( lmao

[corsakid]

Love this car ... Proper cool

epic build mate. To me this car is even more impressive than some of the mega £££ 500bhp let builds you see on here as it has all been done on a tight budget through ingenuity and perseverance. The chargecooler set up you sold me is still doing sterling work on my corsa, though I have uprated the pump to a merc SLK supercharger cooling pump. My car made 260bp at 1 bar on phase 2 so the chargecooler is definately doing the job

[djivesp]

That's awesome dude! Yeah it was a good unit I defo would have kept it if it was more straightforward to mount in rwd
I wish this was a mega £££ 500hp let build though lmao

[Benn]

Dude that looks funking awesome. Fantastic build on this too.. Love it.

Wheels give me the horn.

[neilb1798]

most admit for a home build the amount of work that has been done and engineering work is fab looking at a good power figure aswell im hoping mine will get abit further soon just need my rev counter more than any thing else keep up the cracking work mate

[djivesp]

Ay up everyone,
Thanks neilb
Loooong time without an update, progress has been slooww, but getting there

So, the biggest development lately has been a DIY oil-water heat exchanger, which in my case is just an oil cooler inside a case through which water is passed

Started with one of these off ebay:


And it ended up like this:


What you see above is my leak-testing rig where one stands on the blastic bottle to simulate pressure and hopes for no blowout or leaks or liquid cross-contamination

To fit this mothersmurfer I had to move the intercooler and rad forward in the engine bay, and it now looks like this:




It works and doesn't leak, seems like the engine gets up to temp faster now too - my aim was to stop the oil from getting hotter than the water or at least keep it within 10-15 degrees, but without an oil cooler. Oil cooler would have made the oil plumbing a nightmare since there's already a filter relocation kit and I have no space for a sandwich plate on the oil pump, seems like it's working, but the car hasn't been driven yet so need to keep an eye on it.

In other news, tried to sort the tracking out and both the tie rods didn't have any grip for turning, so cut a large nut in half, and welded the 2 halves onto the rod, shifted in no time


Made some purchases too, most importantly these:

z20let pistons with only 12k miles on them,

and some ARP head studs for a Subaru EJ20 motor which apparently just need 20mm taking off the block end to be spot on


So these will be going in some point this year, we'll see how long the current setup lasts or if it even makes it to the road

Also I 'converted' an Asus netbook into my new dash-puter:

Machine out of it's shell:


The motherboard "folded" back and attached behind the screen:


A small cooling 'tunnel' made from polycarb and hot glue to cool the processor and motherboard chipset:


soldered an extension for the on/off switch:


And this is how thin the whole thing is. There's also a hard drive right in the middle of that sandwich!


and there is it semi-mounted.

just waiting to put a dc-to-dc power supply on it and it'll be sweet!

The framework for the wntire thing is made from that fluted polycard stuff which is amazing for building things like this, and GOOD quality hot glue, and all screwed together as proper as possible.
It's crazy how cheap/good notebook technology has become in the last few years - this netbook cost me £50 from gumtree because of a dead battery and a buggered power connector and it's powerful enough to run Centrafuse, Tunerstudio, satnav, has bluetooth etc etc. Just need a £45 touchscreen kit and it'll be perfect.

Also I can't remember If i took pics of this but under the dash on the passenger's side you can see my water injection/windcreen wash tank mounted and in place

It also received some fresh steel lately:


And the megasquirt got a squirtin' (of contact cleaner, TROLOLOL), and wiring got a tidy, connectors packed with vaseline etc.
This was because I kept getting water in the connector and my electrics were going haywire, some leak somewhere.
But onwards and upwards
Thanks for reading!

[novashed]

your talents never cease to amaze me!

[peester]

hi ives, wow things have moved on since i last saw this - liking the wheels, engine bay looks mega spec.- that 8v cylinder head looking lost in there lol
Great work alround, doing any shows/events in it this year?

[shakeyjakegsi]

I am curious to see whether the head studs from the ej20 fit I have an 8v turbo and am struggling to get a set also any idea of a supplier for a MLS head gasket??

[rc]

ahh the hero returns

[djivesp]

Hey guys:

novashed - thanks chap i do try haha!

peester - yes it's just become a bit more proper piece by piece, still off from the ultimate goal but getting there will defo stick with 8 valves for now though - the whole engine/trans will change eventually but i'm hoping to get some years out of this yet . I don't think it'll be on the road yet because of how little time I get to work on it, but it might happen

shakey, I was going by this thread here so I think it'll work - I checked the thread and pitch is the same, but the sods are still more expensive then a set for the c20xe. Mainly because you get a couple more studs than needed - i think there's 12 in the box because of the boxer engine. Not sure about a mls gasket, but Astra 8vt (jay) has been making stupid boost and power figures on stock cardboard gaskets, so no issues there I think.

RC - hai

[neilb1798]

i got quoted for head studs for my 8v turbo 120 i have email somewere if you want to try them

[djivesp]

Shit. these were more expensive

[neilb1798]

sorry lol they are 120 plus 10 for courier and there from ttv racing something like that looking good wouldnt mind one of them for my mega squirt
