54c GTiR GT300 SR20DET Racing Head

Here's a once in a life time opportunity to own a very rare piece of Japanese racing.

- GTiR/54c GT300 Racing Cylinder head (different casting)
- Massive Port and chamber work.
- Nismo 54c Oversized valves
- Nismo 54c Strengthened Rockers
- Nismo 54c Dual valve springs
- 2.3mm Head shave
- OEM 54c solid lifters

The porting was carried out by a Nismo/GT300/JTCC workshop in Japan.
These Nismo parts were only available to racing teams only, the parts were never sold to the public.
Would suit a high powered Drag/Track car, some parts can be sold separately. You will be able to fit this to FWD, AWD & RWD with the appropriate modifications to block.

Head is currently disassembled, this is how i got it. I will have the head checked, cleaned & assembled for the buyer which is included with the price.

Head is located in New Zealand, but will ship worldwide

$2,500

Awesome price considering the rarity & value of the Head & Nismo parts

These images some difference between the race head and the stock GTiR 54c

this is so cool and finally one of the rare, old parts that'd be worth the money. I'd love to know what they did to the block too. Might as well have the head flow tested after the reassembly just for shits & giggles.

It is a really cool and interesting head, its a shame i don't have the time to do anything with it!

I upped mine to 11:1 CR on my new head setup, I wonder what this ended up running at

What did you do to achieve that?

600supersport · 12-12-2015, 12:20 PM

Semi-custom CP pistons. I was considering their off the shelf 12.5:1, but I figured 11 was a little more room for error while still giving me better off-boost response than the old 9:1 since I have a good amount of cam overlap

pTen · 12-12-2015, 12:24 PM

I have never been good at calculating comp but this head with 9:1 comp pistons and 1.5 - 1.8mm head gasket will should be around 11:1? Which imo is a great boost comp for a det.

In the gt300 series they run much higher comp! They run .5 - .8mm head gaskets for a start.

600supersport · 12-12-2015, 12:29 PM

It's cool what some new stock, boosted engines are running for compression...I think the Mazda is 14:1 with direct injection on basic pump gas
