[Firestorm]

Pretty potent little motor ;) Always seem to hear they arent too torquey though, let me know how it goes!

Props for the quick work too man!

[e30guydownunder]

FUUUUUU and your demands

I'm more interested in driving the thing and having it spool! I drove it from the shed to the trailer...then Dad took it to the dyno where it broke!

About 6 weeks ago now I got jack of BMW parts prices. Every single engine component was just costing MORE money. Pistons, bolts, gaskets. It all costs just that little bit more (some cases ALOT more) and I felt I was wandering the untravelled path.

So time to do a 180! I went yet another less travelled path but not really. I bought an SR20DET!

Let the pictures flow!

The humble M42. It now lies in my driveway taking up valueable space!



We spent the first week since SR20 purchase getting ready for the engines arrival (it was over 1000kms away) with tedious tasks like seam welding the front end and painting the engine bay (after all the welding).



I also had to do some rust repairs to the jacking points:


And then more painting:


Oh what a large drivetrain you have there in your E30:


This SR20 came attached to a Z32 300ZX gearbox. A common conversion over here for SR's making some power :)

I then began the huge task of making everything fit and work! First up mounting the engine/gearbag. This was a task completed within 24hrs of SR20 ownership :) Picked it up Friday arvo and had it sitting in theree on mounts by Saty evening. hmmm things are going well!





It's a bit blurry how everything else progressed I was working 9hrs or so at work then coming home and working on the car for 5/6 hrs there so it's all a blur.

Got Coolers?



Before the exhaust mani was modified:



Intercooler mounted



Cold pipe



Dump pipe



New shifter location



Heater and turbo water cooling delete



We modified the position of the wastegate and then made up a screamer pipe :)



All in all was 5 weeks of flat out activity. Here we are the car going to the dyno Thursday Morning. I was expecting to bring it home after work and then go about fitting Mtech spoiler, all the front panels, tidying the insides up further etc etc. There was paint to be laid ont he spoiler too! All so that we could go to a trackday that Friday!



On the Dyno:



But alas it was not to be. With less than an hours runtime and not even a proper power run a puff of smoke out the catchcan. "Hmm thats odd" they shut it down checked it all out. Everything seemed ok. Continued getting ready for the good stuff, lets make some power. Start her up and "knock knock knock" the little man in there with the hammer said hello and he sure got angry with a little rev.

Tuning over, hopes of trackday over. It seems the car fought me the whole way and WON, I was sure I had it beat but a dead engine is a dead engine.

I've been bumming round the last week or so kicking my bottom lip abusing the bottle a lil, scratching my head wondering what to do. The M42 has crossed my mind a few times since. But nope, I'm sticking to my guns and Friday just gone this landing in my driveway:



Yes my friends a standard Nissan S13...well almost. It had a forged bottom end, just about HKS everything up top and a FUCKING HUGE turbo. Yes standard brakes and suspension! LOL.

It's ok I'm not abandoning the BMW stable completely! The car was off the trailer for a grand total of 15 minutes I think. We undid everything on the trailer pushed it off, jerked the motor out then put it straight back on the trailer!

So that was Saturday morning :)

We then spent 1.5 days cleaning and checking the thing over! It sure is difficult doing things quickly and meticulously. Not that the first engine was neglected, it was bought in good faith but I believe it was damaged before I purcahsed it. Any case that is now a distant memory.

forward march with the new contraption.

So it has:
Arias forged pistons
Eagle rods w/ ARP2000 Bolts
Balanced
New oil pump
Ported and Polished head (only minor work)
HKS stage 2 272 exhaust cam , and 264 intake cam
HKS Valve Springs
HKS Rocker Arm Stoppers
new timing chain
all new gasket incl Metal head gasket with Cap screws holding it down :)

I'm going to throw some adjustable gears at it to dial the cams in sweet and there is also a large capacity sump.







One thing that struck us as odd was how the Z32 conversion had been carried out. There were only 4 bolts holding the gearbox on! And non were across the bottom! Have since worked out this has stuff the twin plate clutch that it was fitted with. but in any case. We have taken the time and made provisions in the Sump for some extra bolts to come through the gearbox!



And now I am just waiting on the clutch shop to fix me up with a clutch. Then I can put the engine back in and get to work on the other jobs still left over from the first attempt (I haven't had the motivation to do them yet!)

But before I depart Some pics of how the whole install turned out. Rather neat I recon :)

















All important Side pipe!


The office. alot of work to be done in here. There will be a lot less wiring on show :) As you can see the fusebox was relocated up under the dash : also

Aight Time for me to come clean. Forgive me poor souls, for I have sinned

[e30guydownunder]

$7k could get you some pretty decent turbo Subarus. Gen1 RS Lib wagon or early (94-96) WRX wagon is in your price range.

$7k turbo GX/WRX conversion would be stretching it. $10k is more like it.

A mate's Gen2 sedan. He'd take $7500 i reckon

Aiming for new coilovers, brakes, engine moved back and rebuilt with the cams but no turbo just yet, not gonna have time to reqire the whole fusebox before 29th July!

After that come home rip the electrics apart and fit the turbo / ecu

Epic build thread is epic.

Cheers Polak, I dont seem to be getting much interest from most of the major players on the forums, but I'm cool with that. Doing for me more than anything :)

Yes that time again. Update time :)

I have been busy.

I stripped down the rear end, pulled off all the old brakes to discover the rear wheel bearings were absolutely stuffed. Just as well I ordered new ones for when I pull the rear hubs!

Hubs were removed, holes thru drilled and studs fitted! These babys are only $3.50ea compared to Vorshlags $6.60ea....AND they will never be at risk of backing out, galling or just plain falling out! Obvious complication is you have to remove the hubs.

Anyway the progress!

New hubs fitted in the arms with new bearings and new studs.


Slip on the rotor spacer


Slip on the rotor, locating bolt thru it and the spacer. Slide on the caliper and caliper bracket


Bam Rear Brakes done. Yes I checked and no the standard handbrake does not work. But I already have a locking hydraulic one on the way :) This will be plumbed inline, not the most ideal (for the hardcore drifter) but will do for me. Will be used to park, and screw around at skidpan days :) maybe the occassional drift practice if I get bored.

Here is a front hub with the studs installed:




Boy they look long? Well not really once I have all the brake hardware on there and my 12mm spacers :D





And a picture of the front setup, your average guy will be none the wiser :D Hopefully they will be up to the task!


Note Front hubs not installed as I am negotiating some new coilovers currently and will wait to install the new hubs on the new struts!

Wow, I can't believe I never read your build thread. Very impressive work, can't wait to see it all buttoned up! :bow:

[e30guydownunder]

My Groton arms are still going strong, this is the third season and I don't go easy ;)

[F34R]

I did not read much of it, just the parts you bought and saw the pictures. Over all nice build! FYI the Groton control arms are shit. I ruined a set in a season of tracking. Meyle all the way =)
