Unofficial Honda FIT Forums - Rb33dett 3.3l Gtr

RB33DETT 3.3L GTR

Being done by RIPS in New Zealand. Some other juicy discussion too.

http://www.gtr.co.uk/forum/101521-wo...-up-diary.html

We believe this is the largest capacity RB ever built, a genuine 3315cc based on a RB30 with a slight bore increase and the rest made up of extra stroke.

The enigne is being built for a customer who wants a 1 of a kind with huge torque and drivability, it will have a custom RIPS 4wd RB30 block with CNC billet mains and the strongest bottom end kit we do (over 60 fastners in the bottom end alone) custom billit crankshaft, custom billet rods, custom pistons, hand made RIPS stainless exhaust manifolds, twin 3037s, twin 48mm wastegates, 1400cc injectors, custom RIPS intake plenim, 90mm billet throttle body, extensive headwork starting with a brand new head with all new Tomei components.

We are looking for a real torquie, drivable, 900-1000hp/8000-8500rpm at around 1.8 bar for a street GTR.

I'm also doing a RB33 with a bigger bore rather than extra stroke and later on a RB35-36 with extra bore and stroke so at least I'll get to test them myself.

Next update:

We are not building the motor for massive power, its just to do something different and to have alot of torque and drivability with around 800-900hp.
The exhaust will be twin 3inch going to a single 4 or 5 inch I think.
I'd say she should be very healthy by 4000-4500rpm and have a very strong 4000rpm power band which is perfect for a street car.

Shanef, no the block is not filled at all, its a street engine that will run a full normal cooling system.

Update:

Here's the block brace / 4wd adapter and some more of the fastners:

Exhaust side all finished, what a bloody jig saw puzzle!!! Tight fit but its all in there and will be fine, can't wait to hear what it sounds like, should be real deep and throaty.

Full length street Tomei valve guides and a bit of porting:

Beginning of the puzzle, RIPS bespoke exhaust manifolds:

Motor on the left is a 700hp RB30 with a TO4z to give you an idea of the size, the motor on the right is a RB33 with twin 3037s and twin 48mm Progates:
