talking about Avgas been wondering if you know much about that stuff, most of the people backhome has been saying avgas has same number of octane as the vp, BUT i did try once it does no different in term of acceleration, but my engine temperature is raising rapidly..almost twice hotter than a vp fuel. and somehow my idle is higher than normal it does when im running on vp fuel...on an NA engine

i dont know if avgas act like that or if you ever try and experience different..

Yep that's consistent. The very cold air in high altitudes is also a factor in how avgas is formulated. Please stick with VP fuel or methanol injection or E85 to eliminate detonation when using the 2jz-gte at high boost.

Sorry for taking long to replay my internet was off.
People here use the w58 boks to drag with because the v160 is so scares and expensive. It will handle the 500hp but it depends on your driving if you drive hard it, won't last long.

If you can use the oem ecu its much better then an aftermarket one.
Aftermarket ecu take a lot of tuning to get perfect.
On the exhaust side you don't have a choice so you're doing an engine swap into another car so you need to get an exhaust made up for you wile you busy do it from the downpipe.

wait i kinda dont get what you mean by driving it hard, hard as in throwing the gear change lik roughly or under hard acceleration but gentle gear shift?.

cus i was planing to daily my car, and most probably i will drive the car like full acceleration(not from dead stop) most of the time,but since im a gentle shifter guy so i wont be thrasing on shifting...will that consider as hard driving?

and ya since i only have engine+tranny+ecu and wiring only when i bought the engine, so i will definitely do a custom upgraded full exhaust system, big intercooler,custom pipping and upgraded radiator, since the old car had a busted radiator and busted suspension. but i will definitely do a general inspection on the engine internal including the gearbox too..

even most of the stuff is custom made and temporarily targeting at 500hp as the entrance power, we're building all he thing to a 1000hp standart equipment in mind, so once i found the v160 box i can just fit the new boxs and big turbo and bam here we go 1000hp car without having to replace the other part first, before i can achieve 1000hp fix this and that, so its like one way build like 1000hp standart equipment but instead of big turbo i went with oem turbo while waiting for the v160boxs.

Yes like snap changing gears and spinning on purpose then it just matter of time until something breaks. But like you said driving normal it should last but yes it also depends on the condition of the boks. I have seen people race a lot of events on a box and the next box will just break.So it depend on the condition of boks and what condition you put it through

1000hp is not that easy and it is very expensive

i know 1000hp would be expensive, but i think im covered for that lol...i guess till i have v160 in my hand, i'll stick to around 500 for now....

i do curious how long will the refrshed w58gbox will last.since i got to live with it for a moment..i do hope it doesnt as weak as people on the other forum has been saying*finger.cross.

A big intercooler will introduce a LOT of extra lag at the ~500rwhp level. Think about all that extra volume of air that needs to get compressed, with those very small oem twin turbos, before you begin to make boost.

Again, 500rwhp isn't a cost-effective point for the 2jz-gte.
