Guest johnymaddog Posted January 1, 2011 Share Posted January 1, 2011 I did mine on the cheap with the total cost of under £1500, although I was pretty lucky. I bought a '92 soarer with a manual R154 box for £400. MOT'ed it and drove it around for 6 months. I stripped out the following parts for the conversion: engine, gearbox, prop, throttle cable, throttle pedal, engine loom, engine bay fusebox, ECU, ingnitor, and as many nut and bolts I could. I then sold some parts on ebay and scrapped the rest, getting back a total of £581. Breakdown of costs: Engine/gearbox mounts £80 Honda S2000 pulley and new belt £75 Fuel system(swirl pot, pumps, filters, pipes £300 Intercooler & pipework £350 Propshaft (custom made) £120 Exhaust (3" custom made stainless) £600 I used the datsun clutch master cylinder and made up a new hard pipe with the datsun fittings. I'm still using the datsun radiator with no problems at all, although I will get an ali rad when I can afford it. The engine is stock at the moment but I will be replaceing the downpipe later. The biggest saving over an RB was the cost of the car. I've done all the fabrication and wiring myself (with the help of friends) with has helped with the cost as well. Doing an RB25 would probable add another £1000 to the cost but I would have wanted a RB26 which would have added around £4000. For me it was as cheap to do this conversion as repair my L series.

OustedFairlady Posted January 1, 2011 Share Posted January 1, 2011 (edited) You're looking at between 1000USD and 2200USD for the engine. Whether or not you get a manual trans will affect the price, obviously. If you get the engine sans transmission, You'll need to source an Aisin R154 manual trans from a USDM Toyota Supra (87-92), and a R154-JZ bellhousing from either eBay or Driftmotion.com. The Supra R154 is easier to install, as the extension housing (that holds the shifter assembly) is shorter than the Soarer extension housing. It doesn't fit perfectly, and you'll likely need to do a little trimming, but with the soarer trans, you would likely end up needing to cut a new shifter location or push the engine forward in the bay. Driftmotion sells new R154 JZ Bellhousings for 335USD. You'll need that, as well as the clutch and flywheel. If you're lucky, your engine will come with a manual trans flywheel and not an auto trans flexplate, but that's on your luck. Once you get all that, you should be ready to drop your engine in. Keep in mind that the 1JZ and 2JZ have similar blocks, and share a lot of common parts, like water pumps, etc. Also, the oil pan MAY or MAY NOT need to be changed. I can't remember if they had a bunch of different ones like 2JZs. Just want to keep you informed. I'm pretty knowledgeable about Supra stuff, seeing as how I own three of the buggers.

Not trying to be cheap just trying to figure out how much money im lookin at money wise 1JZ 2JZ installation instructions for dummies,2 weeks, drive it! Read this entry. It is pinned to the Toyota L6 forum. Then research the web for front cut with 1jzgte or 2 jzgte motor. It will have all the wiring included. It will also have gauges. It will save alot of time and effort for you. There are other ways to go about it. This seems to be one of the most straight forward way to do it.Source a custom driveshaft. Go to www.betamotorsports.com for engine mount/ crossmember. There are a number of other small things. No one can tell you exactly what it will cost for you to do this. Are you going to do the fab work yourself? Is someone else going to do it for you? The cost goes up or down depending on this. Just my .02. To get an idea of the cost do the research and add it up. I do not think there is a whole lot of cost difference between the jz motors and the rb motors when all is said and done. Quote Link to comment Share on other sites More sharing options...
Guest johnymaddog Posted January 1, 2011 Share Posted January 1, 2011 Just to add, the soarer R154 is the one you need for the perfect fit in a 240z. It allows you to mount the engine as far back in the engine bay as possible and have the gearlever in exactly the right place with no cutting.

Sketch_hs Posted January 1, 2011 Share Posted January 1, 2011 I spent about 2k on everything, doing all the fab myself Quote Link to comment Share on other sites More sharing options...

I took some measurements, and I admit I'm not exactly sure how much longer the Soarer's R154 is than the Supra's...I was led to believe that it would definitely not fit. I'm not very satisfied with the fact that my shifter is somewhere in my dash... Quote Link to comment Share on other sites More sharing options...
piston Posted January 6, 2011 Share Posted January 6, 2011 older supra 7m r154 will work if you mount the engine back as far as you can. mine sits only about one inch and half forward from original shifter. Quote Link to comment Share on other sites More sharing options...

Driftmotion will take your shifter and make it longer. http://store.driftmotion.com/static/i-r154shifterextensionformk4sc300.php Quote Link to comment Share on other sites More sharing options...
Guest johnymaddog Posted January 6, 2011 Share Posted January 6, 2011 I've put the engine as far back as possible, which puts the back of the engine 2" from the baulkhead, and the bottom of the shifter is towards the front of trans hole. Because the soarer lever is dogleged back quite a bit it puts the straight bit of the shifter exactly in the middle of the center consul hole. I would post some pics but I don't seam to be able to upload them to this site. You could check my build thread at zclub.net. Its in the hybrid section on the forum.

OustedFairlady Posted January 14, 2011 Share Posted January 14, 2011 Wow, that is sweet. I really wanted to put the 7M in, and i thought the soarer trans wouldn't work...as it happens, I have the extension housing...bahaha Quote Link to comment Share on other sites More sharing options...
