garethr Posted May 13, 2015 Share Posted May 13, 2015 Craig at Dyno Torque did a Supra a few years ago http://www.mkivsupra.net/vbb/showthread.php?222367-ls1-supra It's not easy to find a used LS engine in the UK, so you'd have the hassle of importing from the US. LS crate engines seem like good value, but a turnkey conversion will cost you £5K+ on top of the engine, gearbox, flywheel, clutch, ECU, and ancillaries. GM crate engines and gearboxes in the UK http://www.partsworldperformance.com/ The UZ has the advantage of dropping straight in, but a manual conversion would cost, and unless you can fabricate a turbo installation it will be expensive to increase the performance. However, if you have the skill it looks like a comparatively easy job once you have reversed the standard exhaust manifolds to point forward. A small-block Chevy would be the cheapest to tune, but it's heavy (don't know how much CW's alloy block would cost ), and you might not want to suffer a carburettor after years of nice convenient EFI, so you'd need to budget for fuel injection. Also has the advantage that an old enough block would't need a cat. A small-block Ford is a little smaller than the Chevy, but they are both smaller than a UZ, so there's no advantage in reality. Apparently, the OHC Ford "modular" engine is expensive to mod. Quote Link to comment Share on other sites More sharing options...
Hitbox Junkie Posted May 13, 2015 Share Posted May 13, 2015 (edited) Are the BMW V8s any good can pick up a V8 bmw pretty cheap these days? hmm using that parts world with a LS3 376/525 with a 6speed manual, there plate/clutch, and there ECU controller comes to around 10-11k thats with tax paid. and you would need your car on top so a NA auto at 2K brings a total too 13-14K if you do it all yourself. Think id rather get a TT 6speed but then again having a V8 hmmmmm Edited May 13, 2015 by Hitbox Junkie (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 14, 2015 Share Posted May 14, 2015 Chris, what V8 would you recommend for a stripped out weekend toy thats easy on maint for between £1000 to £1500? You will have to up the budget substantially to get something that's not tired out and ancient. You will also be looking at an iron block.

What options would you recommend then, 350 to 400hp NA being the target Quote Link to comment Share on other sites More sharing options...
johnny g Posted May 14, 2015 Share Posted May 14, 2015 What options would you recommend then, 350 to 400hp NA being the target 2UR-GSE from an IS-F, with a Syvecs? Would be expensive, though. If you'd be open to a V10, how about an M5 engine? Although controlling the 10 DBW ITB's might be an issue!! What about a Jag XKR engine? I know it's supercharged...

Chris Wilson Posted May 14, 2015 Share Posted May 14, 2015 What options would you recommend then, 350 to 400hp NA being the target Small block Chevy with modern alloy heads and roller cam on an iron 4 bolt block.

jumpbike Posted May 15, 2015 Share Posted May 15, 2015 3UZ from a Lexus GS430/LS430, bolts in place of a 1UZ so loads of conversion parts available and block is ali, not pig iron. LS have their problems and you have to wait 3 weeks every time you need a part. Something a bit different could be a V8 from an E92 BMW M3, the gear boxes got for under a grand and the engines can go between 1-2k, not exactly a torque monster but rev well and make top end power. Have a look on driftworks, loads of people doing older BMW V8 swaps Quote Link to comment Share on other sites More sharing options...

The 1UZ is also all alloy. It's the 2UZ that has an iron block. Quote Link to comment Share on other sites More sharing options...
jumpbike Posted May 15, 2015 Share Posted May 15, 2015 The 1UZ is also all alloy. It's the 2UZ that has an iron block. Yea, 1 and 3UZ are very similar just more power from the 3UZ, the 2UZ has more capacity but is less power and a massive heavy turd Quote Link to comment Share on other sites More sharing options...
Wez Posted May 15, 2015 Author Share Posted May 15, 2015 The 1UZ and 3UZ do look like good cheap candidates, I am guessing they are easy fitment in a JZA80 chassis, is it just a sump mod that is needed? Quote Link to comment Share on other sites More sharing options...

jumpbike Posted May 16, 2015 Share Posted May 16, 2015 everyone says LS but unless you have actually worked with them its just chatter, to start as I said above, parts are sparse over here, clutches and gearbox's you've never heard of. They are push rod engines, no over head cam shafts etc. which some people will be like eh? price... and as standard engines they don't flow all that well so if you were to turbo one you might be disappointed without flowed heads and aftermarket valve train. The ECU's are quite unreliable also There's variations of the 1UZ, the very first ones have the strongest internals, not sure on a 3UZ but its more power out the box. You can buy an LS400 for a 1UZ for £400 and break the car for more than that including weighing it in. You just need an R154 box, transmission adaptor kit, custom mounts and the ecu and loom from the doner car. To revert back to your original post, cost wise, 300hp and sticking with Toyota, a 3UZ seems your best option. Quote Link to comment Share on other sites More sharing options...
