Now Saki normally I would support you as you know but Maaattte ....Saki wrote:I dunno how easy to bolt in the LS1 will be, bit if its completely foreign, why don't you goto a wreckers and pick up a toyota soarer 1UZ-FE, they make a ncie 210kw there QOHC 4L V8, reliable as all hell, more so than a chev motor! and will set u about about $1500 for the complete motor!
otherwise you could splash out and spend $2500 for a 2JZ-GTE which is a turbo supra motor, but for a 3L twin turbo they make 430nm of torque standard, which for a 1993 motor is more than then new 5.7L LS1 makes!
Otherwise if you wanna go cheap and cheerful a 1JZ-GTE 2.5L Twin Turbo, makes a beefy 380nm.
I did have a supra with a 2JZ and we ran 15psi with intercooler and all that jazz and it made over 550nm of torque, so you'll have no worries carrying that beast around. Some food for thought though!
Don't you think a 4.5lt L6 (80/100 series) with Safari turbo kit to haul that lardy pommy ass around would be far better??
But then thinking about it the Chev is and has always been by far the easiest Jag heart transplant!![The bellhousing bolt pattern is actually the same as the original Jag box (TH400) on all small block chevs inc LS1/2/3/7.]
Saying the LS1 is unreliable??? based on???? The 240/250kw VY series 1 onwards are no problems at all !? No they don't burn oil , shit main bearings / gudgeons or any of the other RUMOURS you may have heard which may apply to VT-VX/VU only. At 120km they will return under 10lt/100km with 3.46 gearing too!!!
Gos ... you will find the older iron block 350's make a LOT more torque lower in the rpm range than the LS-1 (nothing really happens till after 4000rpm) .. Then they turn into fire breathing animals
Bottom end can be significantly improved with a decent set of 1 5/8" TRI-Y extractors and if needs be a COME St-1 cam upgrade.A better motor given the weight if you can find one for the right price is the LS2 6.0 L98 engine ... these things HAUL ASS from low down in the RPM range and pull like a 14 year old all the way to redline
IMO the cheapest/most effective way would prob be to run a 383/400ci small block[iron] ie from Amcap/Goodwrench (crate motor)
If too much barely makes the grade simply add a Powerdyne or similar huffer kit with intercooler (plenty room in an XJS)
worth a look..
