2JZMKIV Posted January 29, 2015 Share Posted January 29, 2015 Going to buy single turbo kit for my 96 tt jdm supra Recently bought, Aem infinity -8 with p&p harness all sensors (egt, wideband etc..) flex fuel sensor aem 320 lph fuel pump aem fpr Going to buy, ets fmic id1000 rmr or hks fuel rail now engine internals will be completely stock with these parts installed i want to go with 6266 gen 2 which i think will be enough to push 550whp at least on low boost (e85) question is which a/r ratio ? im thinking of 1.32 a/r for low back pressure i read that bigger a/r is less restrictive the exhaust flow will be but is it too big any one had experience with those ? although the turbo is pretty small i don't know what kind of result i will get my friend runs pump fuel 98ron stock internals gtx3582r he pushes 538 whp (dyno proven) on low boost and lag level is negligible but turbo flutters a lot i'm not an expert i just read a lot and observe well any help or opinion would be highly valued.

Swampy442 Posted January 29, 2015 Share Posted January 29, 2015 1.32 ar is huuuuuge, yes you'll get more top end but you'll sacrifice spool time. 550whp is roughly 650 real hp, if thats your desired low boost figure whats your high boost power plans? You don't really want to go much over 700 on stock internals. Is it a road car? Track car? If its a street car driveability is the key, an many guys on here who've been here and done it will tell you, bigger isn't always better.

Chris Bailey Posted January 29, 2015 Share Posted January 29, 2015 (edited) I'd go 1.00 A/R, Best of both then. Quickish spool and still enough poke at the top end. Lee @ SRD recommendes 1.00 A/R Edited January 29, 2015 by Chris Bailey (see edit history) Quote Link to comment Share on other sites More sharing options...

If its a street car driveability is the key, an many guys on here who've been here and done it will tell you, bigger isn't always better. Not a track car not a street car i drive it once or twice in a month driveability is not even in the list 4 months and only driven 100 miles odometer really close to 60k miles because its from japan its in km 99xxx something back to our subject a/r 1.00 and 1.15 makes sense i want keep it top end a bit i really don't know how much can 2jz withstand with stock internals some people say 1000hp some say 700hp my goal is no more than 800 hp high boost and no lower than 600 hp low boost will be running low boost most of the time i'm sure of that.

You have gone from 550whp to 800hp? That changes things a lot! Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted January 29, 2015 Share Posted January 29, 2015 700bhp on standard internals, anymore and you're pushing it past the limits. Maybe might take 750bhp with ARP Headstuds, Mainstuds, Rodbolts. Quote Link to comment Share on other sites More sharing options...

Chris Bailey Posted January 29, 2015 Share Posted January 29, 2015 So any advice on max safe psi ? Not sure...My dads runs 1.8 bar on an uprated engine with ARP Headstuds, Mainstuds, Rodbolts and Clevite Race Bearings. Apart from that its a standard longblock, and its held up fine.

2JZMKIV Posted January 29, 2015 Author Share Posted January 29, 2015 i was thinking 1.8 so it should be 1.8-1.7 something safety comes first safety is above everything Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted January 29, 2015 Share Posted January 29, 2015 Forget the boost pressure, focus more on the power. 700hp tops is all you'll want to push through a stock engine. No being funny but have you driven a 700hp, rwd car before? Quote Link to comment Share on other sites More sharing options...
Gpro Posted January 29, 2015 Share Posted January 29, 2015 seen one running 850hp on a stock engine with cams on 2.1 bar with no issues for a couple thousand miles. In america they all run 700rwhp on stock engines without issues, 800rwho is the 50/50 territory Quote Link to comment Share on other sites More sharing options...
2JZMKIV Posted January 29, 2015 Author Share Posted January 29, 2015 (edited) @Swampy442 nope, but been in one know how it feels also i won't be going full throttle max boost on the next day my first car was rwd although not so powerful my supra is close to 400hp bpu mods now i don't go full throttle in any car unless i'm 100% sure i can control it and had certain experience with it seen a lot of crash videos on youtube most common problem is over confidence which i'm aware of and i never overestimate myself.

Gpro Posted January 29, 2015 Share Posted January 29, 2015 By the way, your going to need 2 fuel pumps for that hp, a walbro 400lph maxes out at around 710bhp so you will need 2 aem 320lph to hit 700-800hp Quote Link to comment Share on other sites More sharing options...

Guest Budz86 Posted January 30, 2015 Share Posted January 30, 2015 Big fuel system including injectors, rail, pumps and FPR. You'll also need a clutch and ecu plus mapping; those are the main bits. The 6266 gen 2 is rated to 900hp, but you'd only get that safely with a built engine. As others have said, 700 is the tops you'd want to go on a stock block. As for an A/R, I'll be going for a 1.00 for the balance between spool and top end; I'd expect that to be very close to, if not over 900 hp, but that will be on a built block with a raised rev limit. I expect full boost by 4.5k and that will probably be around the 2 bar mark Quote Link to comment Share on other sites More sharing options...
