I'm enjoying reading about this project. I am not that mechanically inclined, but good to see you guys can put anything into an engine bay. Will the weight difference affect the height of the front suspension at all? Hate for the ass to dip too much.
So what are you going to fill in that large gap between the motor and the radiator location? Lunchbox to keep your pizza warm? Pet carrier? lol
hehe what do u know?! someone IS interested after all ahaha! for awhile there i thot no one could be bothered about our lil project =) weather's pretty hot here all year round (tropical climate) so pizza's generally STAY warm - and... the space in front has been nicely filled up but didn't take pics - altho the pet carrier was high on the priority list we couldn't find a pet that could err.. take the twin turbo heat so we opted for a bigger thicker aluminium radiator instead, and big mama fan as well - so the engine bay's nice n compact now. top wiring man's been called in 2 wire the whole thing up as well so he's busy figuring out how 2 re-use the stock XJS dash n dials, on the 2JZ (accurately of cos)...
by tomorrow we should be able 2 start the car so yea it's lookin kinda good. as for the front being a lot lighter now the ride height seems unaffected at all surprisingly - it was carefully measured and the car seems 2 be the same as last time altho the 2JZ is SIGNIFICANTY lighter than the XJS V12 engine. nevertheless we've sourced a set of koni shocks n springs 2 replace the 30-yr old stock jag sticks =) also bought some rims yesterday - here they are:
2-piece dunno what brand 17-inch rims from japan (ripped off a BMW). PCD 120mm , 5-hole '2-piece' rims. rear rims are 8JJ and front is 7JJ, negative offset for that deeper dish sorta look. they came with nice very wide tires as well! rear 255/45/17 and fronts are 225/45/17... they will be sprayed a flat black color 1st before putting 'em on =) here they are:

anyways more 2 come soon!

Ahhh, the big 'turnover' day, hope it goes well for you. Good idea with the new radiator and fan, doesn't hurt to help cool down that engine and turbo. I'm just amazed at the different pieces you can put together, and with all luck...make it work. gauges on the dash should be fun, can't wait to hear how that turns out.
Glad you could also find some wheels that'll fit. And here you were worried. I assume these are bigger than the stock XJ (not my specialty)?
keep the pics and updates coming. At least one of us is watchin. I'm sure the tech guys like reading also, as they can appreciate the challenge you've undertaken, they just haven't thought of which question to ask first.

haha thank u brother 
we'll probably only add gauges in a very conservative manner cos this after all is no jap car, it's an XJS so probably only boost meter, turbo timer, and oil/water temp and pressure so as 2 not make the stock dash look like a plane cockpit hehe! plus my dad wouldn't know what either of 'em is anyways hehe!! we opted for a fluidyne full-aluminium racing radiator coupled with a big mama fan, which my fren calls a tornado generator. btw have u SEEN the f*ckin' size of the stock XJS radiator, IT IS massive man! it looks like it came out from a Scania truck! it certainly weighs as much as a scania that's for sure!! 
the wheels are 17-inch, yes they're bigger than the stock XJ rims, altho not the best lookers, they're certainly better (in my opinion) than the stock ones - which are THE ugliest 15-inch pieces of sh*t anyone's ever laid their eyes upon. what was jaguar thinking?? yea i know it was back in the day, but still! they're also a mile wider too which's good to give it that lowered stance menacing look.
hehe was only kidding when i mentioned only u was interested hehe, it's fine even if no one is - cos i'm not searching for praises at all, all i want is 2 provide info 2 anyone wishing 2 do the same 2 theirs, and let 'em know it's definitely do-able  after this is done, we're gonna drop a supra engine into my uncle's ancient, abandoned, rotting Triumph TR7 which is tiny compared 2 the XJS.... my cousin did a mini-cooper with an RB20 skyline engine as well (mounted in the boot and rear seats) will try get pics of that... it can't even move in a straight line cos there's just 2 much power for that little banger.
hehe anyways if u guys think what we're doing's tough, wait till u c this folks:

went 2 see the jag again today - engine has been started... wow it sounds nice even tho exhaust piping hasn't been done yet =) it has a bassy low rumble and the turbo whistles and hisses when the gas is slammed. of cos it's kinda rough still but should be smoothened out... here are some pics of the intercooler piping - which's NOW complete.

WOW, such an interesting project, among others!!! I gotta say that Jag is really heavy and I hope that the Supara engine will not be overworked. How about electrical?? will you guys replace/retrofit the ecetrical system?? What kind of tools do you guys use??? Do you have scantools?? emission tools?? Thanks!!1

wtf are scantools?? emission tools? i presume they're tools 2 detect ur emission gases from exhaust? if it's that then hehe i doubt it cos nobody gives a shit about the environment over here bro, people only care about their car being powerful and that's that i guess. hehe why? u want me 2 do ur car? yea i hope this 2JZ can pull the XJS, but one thing i can DEFINITELY say is that altho smaller displacement, this 3.0l twin turbo will pull WAY harder than that V12. sides i don't know many engines that get souped up to 800-1000HP with stock internals (engine block). my neighbor's supra MK4 is living proof, almost 800hp with stock pistons and conrods - car gets raped on a daily basis - still good as ever.
hehe the wiring is difficult 2 comment on, as it's still being done and i'm no wiring master. one of our top 'wiring kings' has been called in 2 fully wire this XJS up, toyota style. but it's cool, he loves a challenge. EVERYTHING inside the XJS has to be the same, dash, dials, meters - everything. there can be no evidence of toyota in the driver cabin, cos that's how my dad wants it. only thing will be boost meter and oil press/temp hidden in glovebox.
yesterday we got word from cousin's fren that their yard's about 2 do another old skool sports car - really one of a kind in our nation. it's a lambo countache (is that how u spell it?) gonna be transplanted with a f*cking ferrari F430 engine. wowie!! will try snap some pics!!

If you don't have scantool (diagnostic equipment) then how do you troubleshoot issues like the engine light coming on, like if a sensor did not work, or something like that. How do you deal with ignition timing???? do you just get good engines and not worry about it??? i know that in japan, they have tough emission laws and you cant run an engine after certain miles. how about you
By the way, that jaguar with the viper engine is great i must say that the viper itself looks much better than a jaguar, but i am assuming that the viper crashed and you pulled the engine. awesome. can't wait to hear from you. please keep in touch i would love to see what else you are working on. I am saving all pictures on my computer and i hope you don't care because they are just so cool!!!!! Here in america, your shop would be the most popular in the entire USA i am telling you. but try and get a hold of such a nice engine like the supra or nissan turbo good luck
Hoep to hear from you

ok if scantools are diagnostic equipment then yea we got 'em, we just don't know what the f*ck they're called so if scantoolz is da name then well SCANTOOLS it is! hehe! they may have tough emission laws in the land of the rising sun, but we ain't in japan are we? as long as the engine's in good shape then we'll pop it in bro. 2ndly if it's in good shape it shouldn't be belching smoke or anything (not that we care anyways about the environment)... so the rule of thumb here is - if the engine's healthy, and it is power loaded, then that's all that matters. everythin else is secondary 2 those facts.
uhh maybe i wasn't clear but actually i jus found the pic of the XJS with viper engine in it on the net, was just exclaiming how cool it was that's all - i didn't say we did it or anything hehe so sorry if u misunderstood. only the pics of the GREEN XJS with the supra 2JZ engine is our project man. the viper XJS is not, jus came across the pics man. viper don't necessarily need 2 crash for its' engine 2 get pulled man, cos another cousin of mine staying in san diego USA actually purchased a corvette C6 engine from chevrolet, so it didn't come from any car at all. ur last line confuses me a little as well
"but try and get a hold of such a nice engine like the supra or nissan turbo good luck"
but we are dude hehe!! the 2JZ being popped into the XJS is a supra engin man. maybe wat u meant was u wanna see MORE projects that're being done by my cousin's yard or wat?

Oh Man, The more pictures the better I am so all over your forum postings, I visit them everyday. Please keep feeding me anything you got as far as pictures. I am like a crack baby who really needs the stuff. HEHE
I was just wondering, about the last line of your post, "How do you get the engines? If you could bring them cheaply to USA, you would make so much moeny. I was just saying how people here really value SUPRA and NISSAN turbo engines. It is a rare thing here. One issue- thos pesky emissions. I don't know how you could get the engines here. I would love to hear more. Will read tomorrow.
Post as many pics as you can. I can't wait. As long as you have time :)
