All stock, 440cc inj, 4bar feul presure, with Walbro pump. I dont think its @ wheels, should be at flywheel. Still, thats same nm. as std R34 GTR with more kw. Stock turbo's can go up to 1 bar, but its risky with ceramic exh wheels, they are known to brake.
Next upgrade should be turbo, to get 300kw+

nicely done
😀

Got some new bits for the motor, Stainless split down pipes. Should give a few extra hp.

Also fitting Electronic boost controller and wideband O2. Aiming for 300kw on pump feul.

Nice

What did your import cost work out on?

Think it adds up to about R1700 in total, saved a lot on duty and tax as the package was marked as trade samples.

What did the down pipes cost in dollar....I want to import but want to guesstomate first before I over run the cost.....

The were $90 on ebay, anything from $90 -$130 for RB26. Shipping $50.

Thanks.

Here a dyno print of std RB26DETT @ 0.7 bar. 260.9kw. Note flat torque curve between 3500-6500 rpm. Twin turbo's !

Some new ignition coils, since some of the old ones are a bit suspect.

Decided to go with a single turbo upgrade. The cost of 2x garrett ball/b turbo's are just too expensive.
Here is the new setup: T66 Ball/b turbo, stainless manifold and 50mm ext wastegate.

that will bump the power up quite nicely 😂

NICE!!

Test fit. Everything fits perfect. Need to build exhaust pipe, boost pipe and oil pipes.

AWESOME!!!!

that is wikked, i'm very jealous!

Did some tuning on the dyno. Ended with 300kw, and power still climbing, but keeping revs down to 7500 rpm.

Just a quick video clip, road was a bit damp, so there was no traction.

But you've got almost a 100Nm less torque at 3500rpm with the single turbo!!

And you're only getting similar or increased torque after about 4500rpm...

I know, not very happy with single turbo. Should have stayed with twins, a bit late now !
