indestructible engine

Runaeh

hi, want to make my 2jz almost a indestructible engine, how do i do that what file do i need to edit 🙂

stonedmonster

alright first of all what is the folder name for the engine
or which mod is it

Runaeh

its the one oxman99 made 🙂 i just need to know what file, the mode doesnt matter 🙂

stonedmonster

yeah it does because if it doesn't have the source you can not do anything to make it indestructable also do you have a link as i don't have that one

Runaeh

i have the javas for it.

Under the Javas. edit the piston max RPMs, do the same for the connecting rods, pistons and block as well. I. Did this with BB93s LS3 and get out to 8750RPMs. Let me know if you need any further help! Also where the heck did you find source for the 2JZ?!

You can more in depth edit the connecting rod length, bore of the pistons/block and the crank specs to get some power out of it and effectively strengthen the engine.

My 1.5JZ hybrid goes to 9750limiter and can take 10k but I like to place limiter to ensure safety. I highly recommend copying real spec parts as just putting in random values can really upset the compression ratio and the engine will not start. CP, BC, and Tomei make great parts in real life and they're specs are very fun in SLRR.

i just want it not to break with boost so i can make it like the ones on YT with like 4.5 bar boost 😃

damn! 4.5bars hahaha I only run 1.58 (23psi)for street spec through T88 turbo. Write up some specs and if you would want to share those Javas I will gladly help you rescript to awesome spec 😉

My thoughts we give you some 282/282 cams with 12.5mm lift
142mm Tomei connecting rods
10:0:1 compression (will calculate the crank center to top and cylinder length)
I recommend 1.58-2 bars but I can tune turbo to any spec and WASTEGATE as well.

Runaeh

its oxman99s javas so not gonna share them, i got them to make some sound mod for it 🙂it already has real specs it just doesnt hold the boost for long before its broken..

the engine btw is on gom-team

JUDAS_MENTOR

Ahh you acquired the Javas from OxMan himself, understandable! I know the 2JZGTE engine is on GOM but sourceless, I have modded 1JZ source with Shift2 sounds. Anyways sent you PM but I will post here as well. Maybe boost is too high? Very high performance single turbo set ups run 3.1-3.44 bar.

Runaeh

even if i have it at 0.5 it breaks, it just break later later than 2.0bar

JUDAS_MENTOR

That's odd I haven't ever encountered a problem like that. Not running an ebay manifold? lol

you raised the RPMs I assume???

Runaeh

nope but i think it has something to do with T_loss in cylinder heads maybe

JUDAS_MENTOR

On my Java checking.

whats you T_Loss spec??? Mine is set at 80 (yet to have messed with it)

Runaeh

its at 90

Added 20 minutes later:

T_loss is at 90 idk what it does but ill change it in a sec

Added 13 minutes later:

it helped alittle but it still gets broken fast:/

JUDAS_MENTOR

Hmmmm sorry for the slow reply busy texture editing I'll shoot you some more JZ specs for the head, there's a value. Below T_Loss as well haven't ever tweaked this as stated running stock 1JZ script for those.

Runaeh

its my engine block now that breaks now,rest is fine :/

Added 9 minutes later:

its set to 10k rpm max

Added 27 minutes later:

what is your vmin set to ?

Added 1 hour 3 minutes later:

mine is 91.26

JUDAS_MENTOR

sorry for the slow reply, got busy with some projects and life lol

	intake_valve_diam = 34.6;
	number_of_intake_valves_per_cylinder = 2.0;
	exhaust_valve_diam = 30.0;
	number_of_exhaust_valves_per_cylinder = 2.0;

	cc_dome_safe_clearance = 18.7;
	maxRPM = 20000.0;
	inertia = kgToInertia(6*0.22);

	T_loss = 80.0;
	Vmin = 86.8; // in cc //

my set up with oversized +1mm intake and exhaust valves

here is my turbo set up, again i'm only on 1.58bar but maybe try playing with the turbo script???

P_turbo_max = 1.58;
default_P_turbo_waste = 1.9;
P_turbo_waste = default_P_turbo_waste;

	max_waste	= 3.5;
	min_waste	= 0.5;

block set up helps make this tough as

bore = 87.000;

	crankshaft_slot_ID = 33;
	crankshaft_bearing_slot_ID = 41;
	cylinder_head_slot_ID = 19;
	transmission_slot_ID = 35;
	oil_pan_slot_ID = 31;


	cylinder_length_from_top = 133.80;
	crank_center_to_cylinder_top = 249.97;

	rpm_idle = 950.0;
	time_spark_min	= sparkAngleTo4cycleTime(350.5);
	time_spark_inc	= sparkAngleTo4cycleTime(360.5)-time_spark_min;
	time_spark_RPM0	= 2600;
	time_spark_RPM1	= 3600;
	RPM_limit	= 10000;

	cylinders	= 6;

connecting rods

length = 142.00;

	maxRPM = 12000.0;
	inertia = kgToInertia(6*0.500);

crankshaft

stroke = 94.00;
main_bearing_diam = 0.0;
con_bearing_diam = 0.0;

	maxRPM = 10000.0;
	inertia = kgToInertia(12.300);

pistons

bore = 87.10;
length_from_wrist_pin_center_to_crown_base = 50.00;
crown_height = 20.00;
crown_volume = 86.5;
length_from_lowest_safe_belt_to_crown_base = 40.00;

	maxRPM = 10000.0;
	inertia = kgToInertia(6*0.390);

this should be an easy 10-11k set up and safely go into boost at 2400-7800RPMs.

hope this helps.

Runaeh

its my downpipe and intercooler now, have fixed everything else 🙂

could be nice to make something like this https://www.youtube.com/watch?v=UrEkMHJXFKw&list=LLXjo-lIHvDQWMiesAFW3zdA&index=43

Gaveup

setMaxWear(kmToMaxWear(311000.0)); <- make that number bigger and it makes the part last longer.
