Well as the title says i am wondering what rods to put in my motor, i have a set of tested and preped stock items and a set of spool rods but have heard and seen photos of both smashed. Now i was aiming high like the 1000hp at tyres mark, but am cutting it back cause it will never see traction otherwise, looking for around the 700 mark maybe slightly more.

Been looking at Howards rods, argos, etc etc etc, what do i do???

need some options of what people have used

A little bit lighter. I chucked out the rod specs for the argo's. The carrillo ones are around somewhere

Carrillo use their own CARR rod bolts. They can be used for unlimited rebuilds. If something happens to your piston rings or pistons you can undo and refasten them as many times as you like. Some very quick cars use both of these rods - one I know of is in the mid 8's.

If you have the money to spend just remember that the carrillo rods are lighter, about 70-80 grammes per rod if I recall...

Less reciprocating weight will give you faster acceleration and higher rpm.

The difference is nearly 1k between the Argo v Carrillo and you wont get much change out of 2500.

any h beam rod is rated to the 1000hp mark so i don't know what you are all talking about....

its the rod bolt that must be a good quality item......

the only way it would throw a rod thru you block would be a shitty build or the rod bolt has let go.... and that's the only reason, you will never bend a h beam rod unless it comes down to massive pinging or hydraulic lock.... end of story and if it does ping, it will loosen the rod bolts anyways...

Ive seen Carillos, Argo, Eagles, Scat and Spool rods fail - all have been due to oil starvation. Any rod will fail if it welds itself to the crank at high rpm.

Rod choice all comes down to your budget and personal preference ( and what you hear )

My engine makes 560rwhp and turns to 8000 rpm daily - it is over 12 months old and has done 126 power runs on a dyno in that time.

There are a few XR6 turbo engines making 620 - 650 rwhp with Spool rods now.

So I know they are good and there are plenty of people and trade customers using them in big power street, drag and drift cars and have been for years now.

Hope that helps.

    • I haven’t taken them out of the cases yet    inside the box is this packaging which is pretty much like a massive blister pack 
    • Purchased a NC MX5 a while ago Basic suspension mods done, BC coils and Whiteline sway bars  New DBA calipers, discs and pads Added some 17 x 8 Konig Decagrams with 215/45 17 PS5's Added some typical NA bolt on's, i.e. full exhaust and intake  Added 0.5ltrs with a MZR2.5 swap, nice bump in torques  Found a detachable hard top which is locked in for a colour match with my local paint shop in Feb 25, this also includes some PDR as it has received a few love taps from parking in the local shops when in the hands of my Minister for War and Finances, me, I park nowhere near other cars and typically park on the street The little thing is awesome, I drive it everywhere, it handles like a dream whether I'm up it or just cruising  But now,  because I'm a idiot, I keep looking at turbo kits....... did I mention I'm a idiot Why is dose so appealing  All of the NA 2.5 glory, well.......until sometime in 2025 anyway....🤪  
    • I would not be surprised if you are the only person on earth that has the interest/desire to do that lol.  The Haltech base map is a really good starting point, the car will fire easily and drive very well, even on mild boost levels. To me, following your advice sounds like some sort of ancient Chinese water torcher lol (this is not an insult Josh, never change <3)
    • Those car show concepts from the 2000's and 2010's like the Floria and IDx were brilliant and should've gone ahead, at least one of them. But neither Honda nor Nissan are thinking about affordable performance any more, which is truly sad.  Even if Toyota's liquid hydrogen ICE development reaches the point where it's commercially viable and the infrastructure to support it, Honda/Nissan would have to wait until Toyota allow fee access to their patents to offer it with any smaller performance models they released to take advantage of it.  
    • A sporty manual RWD coupe with a IL4 Honda engine would only be a good thing I assume we won't see anything released for a few years though, unless informal talks and designs have been going on for a few years,  and due to the current, and future, emmisions and safety requirements, I assume anything "sporty" they would do would be at least some hybrid thingie And hopefully anything they are thinking of has nice lines, without lots of plastic and fake bits hanging off it like that horrendous FK8 that looked like it was designed by a 13 year old The other issue of course in the current market is cost, currently the type R is around $70k, a twin is around $50k Meh, I'm old and grumpy and would rather buy a older model car and waste my coin on that than buying anything currently available new
