Evening chaps

Its been a while since ive been on here as been waiting patiently for my engine to be built on the cheap by family member. Good news all is well and the engine is almost ready to go.

I am aiming for 450-500hp eventually and currently i have standard rods that are shot and peened. I think these would be pushing there luck at this power. Can anyone recommend a set? Ive struggled to get max hp numbers for some online. Also is the arp bolt upgrade worthwhile under 500 hp?

Many thanks as always

Brad

No need for rods. Proven to take over 600bhp. Rod bolts are up to your but you’ll need to press the old ones out. For 500bhp I wouldn’t bother with them [thumleft]

Plenty of big HP builds out there with standard rods and standard rod bolts (500hp+), stick some forged pistons in there 86mm if your block allows it and a MLS headgasket with ARP head studs and you will be good to go [thumleft]

Thanks guys.

Engine just been re sleeved and has 86mm JE forged pistons among other goodies.

So i will save myself the expense of rods for now. Even better if i dont have to upgrade the bolts. I cant find any cases of the oem bolts failing which is promising.

I will do. Will hopefully do a build post at some point. Been a long term project limited by funds. Hopefully now can move along at some speed!

Yeah it’s not easy mate. 4 year mine has been off the road. Admittedly I did nothing for two of them!

If you havent put it back together, i'd strongly look into not using a sleeved block.

They never work on the 3S and i've only heard of 1-2 not failing.

Your best bet is to source a 98 NA block with the strengthened water pump corner and denser material and stick to 86mm pistons.

Thanks for your advice guys. I have spoken with my tuner and he has also had mixed results. Fortunately i have another block which we are now using. Looked rough on the outside but turns out to be perfect on the inside! Best news is one of the guys at the shop wants the sleeved block for his gt4 so it didnt end up costing me anything [thumleft]
