My brothers Golf mk1 with 440hp on a GTX3071R spool pretty good, run like 1,5bar (can’t remember 100%)
Pretty driveable for the streets (hes old caddy with 360hp GT3076 was not!)
And run 12 on a 1/4

So as I've now gotten the exhaust manifold and injectors for the 023 swap I'm considering getting everything onto my motor so full 023 hybrid with 550cc @ 4 bar. Then mapping it very safely, run the turbo in for a bit and after a while build the engine (or well, rods).
I have also seen threads of people running 023 hybrids on stock motors. What would i need to look out for mapping wise?

058 rods will handle 350-400 Nm for a while,06a-19mm trapezoidals are cheesecake(tbf both are on these small frames), you really need rods if you plan to run to high boost at max capabalities. Get maxpeedingrods or something and you will be fine and you dont have to worry.

Alright i will take your advice.
For now I've set my sight on a Mamba K04 hybrid claiming 350bhp.
Would you recommend the 19mm maxspeeding rods? As I've heard they could be manufactured wrong. Otherwise I'll have to source some BAM or AGU pistons too.
But then it might be worth to get a more expensive set of rods perhaps. Opinions?

Get em, i know many people running them on 500-600 for years, they are fine. They are all the same chinese h beams anyway. |

Just make sure you actually measure the clearances and not throw it together blind, there are some surprises to be had.

Very well, what's another 200-300€ for some rods. Anything else worth replacing with the engine open?

you are change rods better use 20pin and use good condition agu or amk/bam pistons new ring better than any cast 19mm pin auq etc pitsons but you are possible good controlling boost not any problem 310-340hp original rods /bam or agu/ |

Think they were saying get the maxspeeding ones over expensive as they hold up. There was a Clubgti thread about chinese rods that said it was bolt failure. I did a load of research on this with parts both in UK & Chinese manufacturing, rod bolt certificate @ Chinese were just a bit less than ARP2000. Couldn't read the writing on the cert but ISO9001 accredited & I know of one UK tuner selling the same rods pretty cheap. Decent set of 4340's from China + ARP bolts if req'd dep on budget if you need peace of mind, should see you through any road boost. I will say the UK manufacturers had some good material based tech to back up their hybrid alloy but came down to 3 times the price over developing a custom part from China- I guess that's the reality of things nowadays. Just my 2 £€$ Also, as said, tolerances & putting it together properly with a good tune make more of a difference than slight material differences for longevity! |

Actually maxpeeding rods come with genuine ARP 2000s. The only maxpeeding failure I know of thats on forums etc was an assembly issue. Everything short of Carrilo etc are chinese rods. Get them with confidence.

Will probably just get the 19mm ones then. Wouldn't want to be risking blowing my daily on stock bananas. Thanks for tuning in  |

It's not the rod itself that fails on the cheaper rods, it's that the big and small ends can be out of round or have wrong clearance and you either spin a bearing or destroy the piston pin.
If you measure everything when putting it together, then you'll be fine. If not, it's Russian roulette.

What do you guys think about GT2871r on the 1.8T?
GT28R looks like a waste of time when a K04-023 hybrid can easily do similar numbers, but the GT2871r looks like a ton of fun. Also when looking at kits and parts for a GT2871r it looks like a pretty doable and not extremely expensive swap.
K04-023 hybrid would cost me a bit less, but considering the GT2871r it's potential it leaves me wondering if i wouldn't be disappointed with just a "simple" K04 023 hybrid build. Holset HX35 looks fun too, but i'd prefer having bolt on parts such as manifolds, downpipe adaptors and oil lines etc.
