Head Studs For An Open Deck Engine

[Count Grantleyish]

Sorry for off-topic but I'm just curious,

What cc are you looking to achieve out of this motor?

What crank are you asking if you don't mind me asking?

Is it Kakimoto Racing 20mm spacer plate and sleeves in the motor?

Good work with the project, keep it up.

Cheers

The prototype is going to be 87x87 (3104cc). The crank is a modified RB30 crank, long rods, custom pistons and custom order dartron sleeves. I made my own spacer plate based on looking at a lot of pictures I obtained of other open deck engines. The engine will be 20mm taller than stock. Its going to be a couple more months to finish but i'll post up the build of it when its all finally going together.

Looking forward to see the complete setup and another q, what turbo are you going to put in?

Like I said earlier, keep up the good work mate.

Cheers

Small for response. Being a big motor it doesnt need to rev, though it will do 8k max. A pair of HKS2530's most likely to maintain a stock appearance. GTRS's at most. I'd prever something some middle ground between these two turbo's, might require some more investigation. Thats a long way off though.

the 2530's should give the 500hp you are after. the gtrs are more of a 600hp combo

wow coming along quite nicely Ian

thats a tad underated for both sets.

HA HA Hardly recognise your old engine block hey!

Yeah 500awhp would be plenty. The driveline is stock in the R34, and I dont want to turn the car into a bitch to drive by filling it with neoprene bushes etc. Ive gone with a coppermix nismo twin plate too, and to make that last 500hp is a nice safe limit. Realisticly I'd be more than happy with 400hp, but the fattest and widest torque band ever. I like motorkarna and sprints. Not into drag racing so much.

better to air on the conservative side

The 2530's should be pretty responsive with 3.1L, take a look at N1GTR's dyno sheets with the GT-RS setup for an idea as to how it would spool up with the larger turbos, as for 400hp with a fat torque curve look at AL's setup (although he has an RB25 head and single turbo it gives you an good idea of what the GT-SS turbos would be like on yours).

looking great mate. my car could not be in better hands! definitely go the 2530s. they will be a great match for the donk and your aims for it. it will be stock response but with 50% more (maybe 100%!) power at every point in the rev range. bellissimo!
