1JZGTE Cheap turbo upgrade	Fri, 13 February 2004 00:22

are there any turbos that will improve performance for a 1jz, while not costing an arm and a leg to modify the intake/cooler piping too much? [Report message to a moderator]

I didn't really word that correctly. "are there any turbos that will out perform the stock 12a's" and wont require too much modding to the intake. [Report message to a moderator]

put simply, no It all depends on your idea of "an arm and a leg" I guess - but most (all?) turbo upgrades will need new intake plumbing, y-pipe, and mounting manifold. Which in itself isn't a bad thing, considering the restrictions of the y-pipe and inlet plumbing [Report message to a moderator]

IF you want to keep it looking fairly stock just hiflow the stockers. If you are really serous about keeping it looking stock but going like a cut snake then I know GCG have a package where they basicaly use two GT25 cores (so they are BB) with custom blades. Expensive though at a good 5k. oyota 1JZ & 2JZ-GTE Ball Bearing Turbo Converion Package:- XTR2JZ-GTCON $5500.00 This is a conversion carried out to the standard set of turbochargers which bolt back onto the engine, with only the oil & water lines requiring slight modifications. The package uses Garrett GT ball bearing CHRA's. Ouch... [Report message to a moderator]

I reckon there is a cheap(ish) way to replace the stockers with a bigger single turbo (actually this is Sean's idea which I am nicking!). Essentially keep the stock exhaust maniolds but join them together with a twin-to-single manifold (home made or from turbonetics). Use a hybrid turbo - modifed RX7 Series 5 exhaust housing (big housing but with internal wastegate to reduce cost) and a T04 compressor and front cover. There's one a bit like this for sale at the moment on the forums. You'll need to redo a dump pipe, and make up new intake piping, as well as modify oil lines - much cheaper if you do it yourself. I guess you could have a decent single turbo hanging off the side for around $1500. Then of course you'll need to have better engine management and injectors - but again you'd proably get away with an E-manage and 440cc 2jz injectors. So essentially, you could get away with a cheap(ish) single turbo....but then there's a heap of other things to spend money on before you'll see much benefit!!

I think you should buy those 1JZ-GTE steel wheel turbines for $1500. Apparantly they are brand new on the for sale section. [Report message to a moderator]
