Well if I am just going for 400 maybe MAYBE 450-500 oneday do you think, what all should I do to get there reliably and correctly, no cut corners.not a thing. you could shim the oil pump. you could waste all kinds of energy and $ installing a thermostatic oil cooling system.
run an oem radiator/ water pump / hydraulic oem fan clutch. stock stuff is all fine for 400 whp
the original engine, built to OEM specs will handle that all day long. provided you are not detonating and have a proper tune. only thing wrong from the factory was loose head bolts due to an incorrect spec used at assembly. if you install just apr studs with the oem gasket it will hold that fine.
you don't even need the turbo motors piston squirters to live at that level. im running a 7mge block with gte pistons (no oil cooling) and have exactly 0 concerns about my oil system at that power level
7m gets the bad wrap as a rod knocker. most (if not all) originate from a few super easy mistakes
1. no enough oil in the motor and whipping around corners at high speed, starving the pickup and loosing pressure. the old 7m like to leak. forget to check the oil, leave the house with 2 qt low and do some 80 mph sweeping corners at 6k rpm. a rookie supra (or any car owner) will make the first 2 mistakes with a car that consumes oil (leaks/burns/combo)
2. motor blows a head gasket and makes milkshake oil. car then drives X miles on this oil, beating the piss out of the pump and bearings. and then it knocks
but I have to be real. getting a car in pieces and not knowing the platform is a huge pain in the ass. I picked up an 1976 mgb like that a while back. trust me, I know cars / what to do and have close to 3 decades of experience working on engines ....there were so many unique "british" things to learn about the platform. and that mgb is like the most simple platform on earth, carburated, simple mechanical distributor, etc. working on that simple platform recently has really made me aware of 2 things for the supra. 1. it is extremely fucking complex / complicated 2. replacement parts are just expensive. I mean for the mg I bought new tires at $31 each, new rubber brake hoses @6 each, new water pump was around $20. I could go on and on. with the supra all that crap is just so expensive and just not supported like other platforms.
when i was your age (here we go....) back in 1998 the supra I first bought was 11 years old. $1400, turbo manual. had a "bad clutch" but really just needed the clutch master. it was so cheep back then compared to now. you are jumping into a game dominated by guys like me now. we have disposable $ and will snipe the $500 parts cars right out from under you while you are sleeping saturday monring this is why things like the dam cps sensor are $200 used, or why a non cracked dash is over $500. its a tough crowd to join at 18
I just want to do this correctly, everyone kinda tells me diffrent things i just need a base idea to work off of and do to run this power level without somthing major breaking.
