Nic Posted August 6, 2002 Share Posted August 6, 2002 Does anyone know Toyota's running in instructions for a new 2JZGTE engine and the initial service schedules? cheers Quote Link to comment Share on other sites More sharing options...
Terminator Posted August 6, 2002 Share Posted August 6, 2002 For the first 1200 miles or 2000KM Do not exceed 4000 rpm maintain an engine speed of between 2000 and 4000 rpm. Avoid full throttle starts:( Try to aviod hard stops for the first 300 km 200 miles. Do not drive slowly with transmission in high gear. Do not drive for a long time at any single speed either fast or slow. Taken from UK manual. Quote Link to comment Share on other sites More sharing options...
Nic Posted August 6, 2002 Author Share Posted August 6, 2002 2000km below 4000rpm That is going to kill me and take forever here:( Now where did I put those axle stands.......... Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted August 7, 2002 Share Posted August 7, 2002 There are TRD break in instructions on MKIV.com Quote Link to comment Share on other sites More sharing options...
Gareth Davies Posted August 7, 2002 Share Posted August 7, 2002 Can't you 'bed in' engines by just going for a blast at max speed? It'll either bed or blow... but at least there is no wait Quote Link to comment Share on other sites More sharing options...

It'll either bed or blow... but at least there is no wait I've heard of this being done on engines which have had new pistons / rings fitted to slightly worn bores, but for a complete rebuild, or new bearing shells, I would go with the softly-softly approach.

Nic Posted August 8, 2002 Author Share Posted August 8, 2002 Alex Here's the story. I was having the same problems you were having with overheating. New rad, water pump, thermostat, rebuilt viscous coupling nothing could cure it. I was also freaquently blowing the front crank oil seal (5 times!) Got a pressure test done and it showed that pressure was escaping into the crank case, ie. ring/bore wear and the crank case was being pressurised causing the seal to blow on spirited runs. Also suspected leaking head gasket causing the overheating problem. Decided to bite the bullet and throw money at the problem, I investigated the cost of getting the block rebored and fitting new JUN pistons but apparently there is no one in HK up to doing the machining work to the required tollerances. The solution was to buy a brand new short block assembly from Toyota (block/crank/rods/pistons, etc) which was suprisingly cheap (£1500, plus I can get 20% discount.) See image attached taken from mkiv.com. I also looked into getting a brand new head assembly, but Toyota don't sell them assembled so it would have cost a fortune to buy all the parts and get the head built up. In the end Phil W came to my rescue and managed to get me a low mileage head from a scrapper in the UK and Chris W has done a fine job of rebuilding it (he posted photos on here last week.) The engine will be built up in the next couple of weeks, hence the questions about run in schedule. I can't wait now to get my brand new engine fired up cheers Quote Link to comment Share on other sites More sharing options...
Nic Posted August 8, 2002 Author Share Posted August 8, 2002 Thanks Terry I checked out the info on mkiv.com, see copy below. 500miles sounds a lot better than 1200miles if it will safely run in the engine, any experts out there with views? Oh and what is valve lash? The following is part of the Formula Atlantic Motor kit instructions, from TRD: To ensure long life and reliability you must properly break in your freshly assembled engine. For a high performance street motor fill the engine with a good grade 20W-50 Mineral based oil. Fill the oil filter with oil before installing it. Remove the spark plugs and crank the engine until the oil pressure comes up on the gauge. Re-install the spark plugs. Now you are ready to start her up. Start the engine and bring it immediately to 2,000 rpm. Vary the engine speed between 2,000 – 3,000 rpm for about 30 minutes. After 30 minutes stop the engine, check the valve lash and re-torque the head bolts. Drain the oil and change the filter. Re-fill the engine with 20W-50 Mineral based oil. Drive the car slowly for about 500 miles keeping the rpm under 4,000. Don’t lug the engine either because that’s worse for the motor than over revving it. After 500 miles change the oil and filter again. You can now use a synthetic oil if you want to. Use a 20W-50 oil and change it every 3,000 miles. Your engine is now broken in.

Alex Posted August 8, 2002 Share Posted August 8, 2002 So now you've bought a new block are have you fitted the Jun piston set in it? and the Jun "sweet as Fcuk" Valve train in the head? If you have I hate you Still with a nice new engine that got a fettled head you should start thrashing thise Ferrari's again! Quote Link to comment Share on other sites More sharing options...
YZF-R1 Maniac Posted August 13, 2002 Share Posted August 13, 2002 mmmm brand new engine.... How did you manage to get a 20% Discount on the short motor??? You lucky lucky lucky man!!!! Cheers :beer Ps oh yeah im new Hi:) Quote Link to comment Share on other sites More sharing options...
Nic Posted August 13, 2002 Author Share Posted August 13, 2002 YZF-R1 Maniac welcome to the group. If you look at my location you'll see where I live/work, I paid the equivalent of £10 for membership TOMS/TRD HK, for which I get a years membership, a nice laminated card with a TOMS supra on it and 20% off any Toyota, TOMS or TRD parts, bargain Anyone up for a group buy on 2JZGTE short blocks???:flame Dev Seriously though, when I get the time I'll try and organise a group buy for list members, it'll be smallish parts such as plugs, pads, filters etc. to make it economical on postage.

YZF-R1 Maniac Posted August 13, 2002 Share Posted August 13, 2002 D'oh Now i feel stupid LOL.. Ah being from Hong Kong you might be able to help me with a small question? I'm in Aus and the supras here are Usually imported from Japan. Well I am looking to import one in the near future but i wanted to try and get an TT Aero(Targa)top with the six speed, but I read on the web somewhere that they only make the TT Aero tops in Automatic. Now if they do that it will totally ruin my plans.. Any help would be great thanks? Cheers Quote Link to comment Share on other sites More sharing options...
Gareth Davies Posted August 13, 2002 Share Posted August 13, 2002 I'll butt in here, someone else from Aus recently here mentioned he'd just got a RHD 6-speed aero (and had some piccies). That variety was never available in europe (or japan). So I was under the impression it would have been a native Austrialian version?! They're pretty common in LHD, so it depends if that doesn't bother you (not from Japan though). Someone will no doubt correct me, but there is a fairly active Aus / Nz supra mail list somewhere. Sorry don't have the URL. Wherever they exist they are definatly VERY rare, and without changing the gearbox around aftermarket virtually non-existent in europe (I don't think anyone here knows of one). Anyway, good luck finding one Quote Link to comment Share on other sites More sharing options...
Nic Posted August 13, 2002 Author Share Posted August 13, 2002 I've seen a few aero mkiv's in HK but the ones that I've had a good look at were all autos. I'll ask at TOMS/TRD HK next time I'm there to see if they know of any manuals. Quote Link to comment Share on other sites More sharing options...
YZF-R1 Maniac Posted August 14, 2002 Share Posted August 14, 2002 Thanks that would be great. I reckon it would be a big job to change an auto to a 6 speed... Quote Link to comment Share on other sites More sharing options...
