1GZ-FE pics and measurements. Drool included.

this is fuzzy memory, but what size twins did Jamie Heritage have before he went to the single?? it's on 4L, so you would need something larger to reduce response even further....

isn't jamie Jaffa so why not just ask him

[oldcorollas]

LOL my bad (my apologies too )

so.. as rumour had it, you went from the twins to a single, partially to reduce response.,... what change in sizes were involved?

and why not get a big screwcharger for it

I agree with Sean's comments, this thing is a torque monster even without FI so there's no need to go for tiny exhaust housings, unless it's being built for tractor pulls or something.

If it was me I'd look at what the 1JZ guys are doing, since each bank of your 1GZ is similar to a 1JZ. GT30's tend to work pretty well on a 1JZ, not quick spooling but not stupidly laggy either and with a very decent top end, which sounds about spot on for your purposes.

I can't even begin to imagine what such a beast will feel like once the turbos spool. It will be like engaging warp drive I reckon.

[oldcorollas]

10psi.. lets be conservative and say about 700-750Nm torque.

[SL666]

shifty: hmm low end response.. 7-10 psi cheap.. chew me

and 'quad turbo' sounds cool

[Norminator]

Bastards ,...Easy on the Bogan stuff hey!

ahaha you forget that i knew you when you had a mullet and a 400ci WB ute! and both were fine examples, might i say!

Sorry i should of pointed out that i now use Jaffa so no apologies needed

Yes the rumour is sorter true + a few other reasons eg what follows
Turbo's where CT26 off the 7m, they did come on boost really savage in a car that weight 1060kg and full boost happened in about a 2-300 rpm band so with this in mind and the turbo;s out so far over the front axle, traction was a real issue with only 225 rears.

So then i relocated a single towards the rear just behind the passenger seat in the rear footwell and boxed it in accordingley. It used the 700hp compressor GT35 wheel and a GT30 600hp turbine side. This was choosen with heat loss in the pipes considered ,.. boost came on slightly early than the twins but spooled over a good 1000-1200rpm range depending on how hot the pipes where. The single made 320rwkw at the wheels on 1.2bar boost so this was probably close to the turbines side limits anyway
Total weight that came off the front axles was about 35-40kg (can't exactly remember now) this made a huge difference to handling and traction as you could imagine, as the weight was also hanging a fair way out and up compared to where the single sat in the footwell.

I would love to run a big screw but it has to all sit under the bonnet for me

I will put a separate reply in for the Turbo's for the 1GZ-FE

Thread Revival !

What happened to the hotrod ? How did it run ?

[Norbie]

Quite a few 1GZ's have been bought since this thread was started, I'm looking forward to seeing someone get an actual 1GZ-powered car running one day.

[The Real Roadrunner]

im waiting for tan to drop his off. i think he has disappeared.

[greywolf]

Having only recently discovered the joy of a Toyota V-12 engine (about 8 hours ago), it's a new pipe dream to build a 1GZ-FE powered car !

Sump is a bitch.

[Talasas]

Has anyone got a price on what a 1GZ-FE is worth in one form or another (other than whole car I guess)?

[Norbie]

Sump is a bitch.

The smart option is to put it in a car that doesn't require sump mods. Hello JZX90.

Approx $6k for engine/trans package, IF you can find one.
