& 1 GT Turbo.(pistons, rods, maybe crank, injectors, hybrid turbo, ecu, etc) to about 600rwhp this requires a rev1/2 engine as block is slightly stronger and it will be for racing and effectively a modern version of the 3SGT engine used in le'mans cars.RedMR² wrote:89mm? Typo?

Must be Red, even 2.2 5S blocks don't go that high!

Paper thin bore walls!
MrSpleen, you'll be wanting 86mm or 86.5mm pistons, not 89mm.
Stock bore is 86mm.
(been there!), even with sleeves I'm not sure you could bore that big 
The key is to make it reliable if I go higher on horse power then reliability will drop dramatically.> toyota-trd-503e-engine-toyotas-entry-into-the> retrospective_gt_gt_toyota_supra_gt_lm_at_le_mans/ I was talking to a reputable engine builder a few years ago about this, he'd seen one in South Africa for sale- apparently looked very similar to the 3SGTE until you tried to pick it up, when you realised it weighed twice as much!..I'm really keen to see how you get on trying to run such wide pistons in a stock block. What turbo will you run, and how much boost? Will you sleeve the block?..ashley wrote:EDIT: was the 503e this fabled thick walled TRD block I've heard about? Apparently a stock block, but pretty sure they actually beefed it up substantially.
Interesting bit of history.
Very interesting.
"why not try to upgrade it" and "what parts will I need" to "I'm building a 600rwhp le mans spec engine" (bet your wife will love that!) in 3 pages..
the post above my last sums the thread up.[b]Ashley[/b] I'm glad to hear some useful comments from you at least, this is the first I've heard about the block being substantially heavier on the 503e/ 3SGT and it may explain why so many people here are saying its not possible in which case I may have to stick with standard bore but may be worth doing some measuring once I get engine apart, as for the turbo I'm looking at GT3582 once engine is built and it should fit nicely with around 20-25lbs of boost, as for the current setup fuel rails, injectors, intercooler, dump valve, waste gate, ecu and intake have all been uprated already so its engine internals and turbo that needs doing next and I'd rather sort internals before changing turbo. I will probably change the inlet manifold as the non turbo manifold actually has better airflow and doesn't make the engine run lean on cylinder 3 and will give better performance.
