e30-323ti

Seedy, you got a link for where you got that clutch from? I run a 2JZ-GE setup behind the 1JZ-GTE, but it's a bit tired after 10yrs of part time abuse.

Looks like it just runs from the battery: (JZZ31 chassis) I don't recall wiring it up on my 1JZ-GTE either...

Ah, TC Kline in the US are where you want to look

Typically, you should not replace 'barrel' shaped springs with parallel shaped springs. Prime example of why not to is the BMW E30, E36 & E46 rear springs, if these barrels are replaced with a parallel springs they will often coil bind before full suspension travel. As they have a really low motion ration (<0.5 IIRC) this put a huge shock load through the middle of the trailing arm due the the long 'lever' action, and can bend the trailing arms. Not to mention the undesireable / unsafe handling side-effects. The likes of the *A6* toyota chassis IRS would be a similar example.

Years ago there was a bloke on NZMMC that had a Chariot with the 4wd Turbo goodness, username: Manny rings a bell. This Guy Random People Mover Pic, on the people mover theme, I see Mazda do a 2.3l Turbo MPV too....

[thread jack] While on the topic of ECU's (and *JZ's) For a dedicated track (circuit) car, why would you choose an ECU that can do full sequential Fuel / Ign (say a Link G4 Extreme, Vipec V88, Motec M800 or DTA80) over one that could only do Waste Spark and Batch / Semi-Seq Fuel (say Link G4 Storm (even the Atom), Vipec V44 or DTA60) Ignoring all the bells and whistles (data logging / traction control / boost control / blah blah blah), obviously even an 'old tech' LinkPlus can do the job.... [/thread jack] sorry for the 'jack yoeddynz - looking forward to see the viva's next incarnation - my 2c ITB's and Alpha-N

Awesome work! Reminds me of the fun times with my old BFMR Re: Brakes, have a look at the DC5 Integra Type R (JDM) they have similar brembo caliper, but is a bit smaller. Also, the front wheel looks a bit set-back after doing the 5 stud swap. Have you got some of those offset caster bushes in there??

Well I'll be, I had always read the same as nick_m 305mm MAX. firewall setback AND 5% of the wheel base MAX. to No.1 for engine placement One of those things you need to read a few times to sink in The T56 Magnum is a nice option (good price), but the overdriven 5th & 6th means you need to run a +4.55 ratio diff for it to be of any real use on the track (from my investigation anyway), then to start to run into driveshaft RPM issues. The new TKO's come in a 500 & 600 lbs-ft variants IIRC Mikuni: No build thread yet sorry.

any one??

Thought so, sounds like a similar number to what I used. Just don't forget the max. 305mm firewall setback, but I think that might be a bit subjective given the shape of the firewall. Luckily in the E30 the front wheels are quite far forward compared to the cabin, so @305mm there is still some room around the back of the engine Nice call on the TKO, plently of shifter position options. BUT, if you're spending that coin, where do you draw the line, as freshly rebuilt Richmond T5 or Jerico 5spd Dog-Boxes are similar cost. Problem being the 1:1 5th, and finding tall enough diffs. In that pic I've been a little excited with the angle grinder and cut the floor/tunnel back to the edge of the chassis rails. There is about 4-5" of floor to go back in, so not as tight as it looks. Keen to see what you are doing with the front end

Same issue (or worst case solution) with my E30/1JZ Loving your work! Makes procrastinating about my project that much easier The 120mm from front axle to No.1 plug, is that 5% of the wheel base (ie. the old OSCA reg's)? That was what I started building mine too, a while ago Are you moving the seat back at all? I've moved mine back ~200mm and run a W58 with the most forward shifter (from a TA63 IIRC). Have a tilton floor mounted pedal box for when I get to that stage. Hot feet maybe??

Awesome-ness My E30 BMW has a 1JZ-GTE sitting about that far through the firewall also. And that bodywork... :drool: What size wheels/tyres are you shoving under there?

...Can anyone recommend someone in Wellington / Hutt Valley who does Alloy Welding / Fabrication. Need some new IC plumbing, modified IC end-tanks and Radiator modifications. Someone who does a good job and won't charge the earth. TIA

Howat Engineering. Out in Lower Hutt, near Bunnings. Have done 3 of my supra diff's & driveshaft mods/balancing.
