Hello kind of a newbie int to the whole 1jz tuning scence having come from tuning renault5s and d turbo engines, i know the need to know of how to tune the engine but......... not sure as to what parts to buy. I have recently purchased a single turbo manifold, holset hx 40 and external wastegate, am just not sure what else to purchase. I am hoping to achive around 400-450 bhp i know i need injectors ecu etc etc just not what sort if anyone can help would be a huge help. Thanks Ollie
What sort of what, injectors? High impedance side feeds for the 1 or 2JZ will drop in. Look for 550cc injectors if you want about 500hp ECU, depends on how big your budget is. Syvecs is where its at, personally Id avoid the Emanage ECUs, but thats just me. Auto or manual? Auto will need some extra fluid cooling. HX40 is overkill if thats all the power youre after, a 35 will be fine.
HX40 is overkill for just that power, but as long as the turbine housing is no bigger than a 16cm it should still spool just fine.
you will need a big external wg just to vent the excessive gasses if you want hx40 run at such low boosts.
i shall measure that asap what if it measures bigger stav? can i get a smaller housing? Well i just need advice on all the parts i need to achive around 500bhp as i say new to this scene. thanks
Look inside the inlet of the turbine housing mate, inside one of the two scrolls there will be a number, that's the 16cm thing. Nothing you can measure TBH. Can get a smaller housing if you can find one, smallest you can easily find is 16cm, 14cm HX40 housings exist, but are rare as fuck. Beyond the above it'd be a hybrid, like the HX35/40/HE351 I made for Zurawski Motorsport a few weeks back. With a smallish housing a 40 will be just fine, and if you want 500bhp it will make it at lower boost than a 35 will.
Ok bud ill check it asap and shall inform. Could you pm a price for your hybrid if its a good option please. Thanks
I haven't got the price to make any more at the mo, but would be £450-500 if only I could find the right bits again!
It's the size of a small planet, and for a HX35 rather than a 40. Did you ever find out the size of it?
Nope, there is no markings on it at all.. Iv got a 12cm one coming from Mitch now anyway Just need a mani & wastegate, injectors and an ECU.. Thinking about using a Vipec V44, I know it's a 4 output Ecu but I was thinking just double up on 3.. Not ideal, but effective none the less.
For 400-450bhp. Any compressor- 8-7-6 blade one is fine, though a 7-6 blade is better if only you could find one. Turbine wheel is the same on all HX35s. Ideally want the 12cm T3 housing, if not a 14 or 16 shouldn't be bad at all on a 2.5. Don't go any bigger. Don't know a part number but there are literally hundreds of variations that would be the above spec.
Thanks stav the reason i ask is going to buy new feom universal turbos and they wanted a part number due to variations of the hx 35 but that should help thanks
