2JZ NA-T update

[lacrssgus14]

Well, I will be picking up my 2JZ from the engine shop on end of this week. It is considered an upgraded TT bottom. Stock TT pistons and rods with Clevite Bearings and ARP hardware. One of my stock NA heads will go on it while I gather the parts and funds to have the other one built or get a TT head.

I hope to have some pics up soon, but as of now the car is in primer waiting to go back in for moulding (fender flares only) then a full paint job and trim restore this winter.

I was just wondering what turbo will you be running. Hopefully something pretty big to take advantage of that nice flowing jz head :)

I will be running an HX-35 (Cummins diesel turbo) untill that becomes to small and I have the funds to move up. Holset's site says 30psi and 500hp on a 6.5 liter diesel. Shiva is running an HY-35 on his 2J at 18psi I think and is making high 200 to low 300 whp I believe. It was a brand new $250 turbo, so I took it to put money into other areas. This is supported by a Tial 40mm wastegate and I will probably be selling my Greddy Type-S soon for an HKS SS or a Turbonetics Godzilla BOV. Dual Walbro 255's and I'm thinking 880cc injectors with a custom rail. Also some giggle gas is plumbed if I would happen to need it.

sounds like a nice project coming along. What rear turbine will you be running? Holsets rear tubine are in cm's instead of the usual A/R. 12cm or 14cm would be nice.

Shiva dynoed above 350rwhp last time i checked. Not 100% though.

Parts came in from Lexus this past monday, after waiting for a backordered dipstick from Japan, my mis. oil system parts are finally here.

Still waiting on my buddy that will be doing the Fbarication on my custom piping and such things, he is busy transplanting a RB26DETT into an FD3S, so good things do take time. Will be setting up for 15psi (max on the BOV) and the car will be run minimally on 103 octane.

Is there a forsure dyno number for an I-6 MKII? Wes's list seems out of date, unless those numbers are still the standing records. I'm pushing for the Chicago Supra meet.

Wes's list hold all the current known/proven records.

Ok, so hoping to top the current power adder number of 421. Got word last night that I might be the new owner of a tranny that can most reliably hold high hp numbers, have to wait and see.

[lacrssgus14]

In deciding to finally update my fuel system I have made some purchases.

2 feet of -8an fuel rail stock, for which to make a cutom rail (dual in, center out)
(6) Delphi 75lb/hr (760cc) low imp injectors
Dual Walbro 255 pumps with braided lines as needed
Aeromotive FPR

Car is down for the season, currently getting suspension work. Superpro, Dobinsons, AGX's, and hopefully some of those fancy Whiteline adjs. sway bars from karaki.

ok i really cant decide and ive kinda been lookin at it but it seems like thers nuthin better than first hand experience...............so i want to ask i was ganna lean tward 1jz but i keep hearing to go 7m because of the turbo and its less expensive also you can it preaty good hp from them???so can someone lemme kno why 1jz i dont kno but im still leanin tword this

[racerxj220]

421? WTF? I'll make that on low boost...

[williamb82]

there are plenty of 7m's out there, and we know for a fact that russ and joel both made more then that, but they arnt here and when russ was on the yahoo list wouldnt post a dyno sheet or tell us anything about his setup. also think of all the people that arnt even online that are making more power or are in other countries and dont visit our site. these numbers are from a limited number of mkii owners. when my 7m is rebuilt i should be putting out over 500rwhp on 93 octane gas and water injection at the wheels. but it isnt doen, and no dyno sheet, so im not on the list.

[lacrssgus14]

I hear you about the people not on the forum and not from our country william, but I really hope to eclipse the mark by a large amount.

Anyway my engine setup is proven capable over 30psi and 900hp reliably, so we'll have to see where this ends up. if i can afford the supporting mods to make the power, it wil make the power.

[racerxj220]

Will, that's what I mean, lol.

[racerxj220]

How's this coming along?
