Electric's the way forward.

Rich is on it...just waiting on pistons and then an 88mm bore on the block.
Same setup as yours is pro 2 cams and supporting head mods minus the COP and skunk2 manifold and 11.7:1 pistons and my eagle rods.
To say I'm excited with anticipation is an understatement.

[NafemanNathan]

Nice! That custom pistons? CP?

[newkid]

What's your plans with the charger? Not the one @nitin_s1 got is it?

Yep. Wiseco with cosmetic HeadGasket.

No Nitin has one already. Im selling it but someones already snapped it up pending payment.

So i thought the Prelude would just need new piston rings and maybe something else and i accounted for up to a couple of grand to sort it. Now piston rings was diagnosed off a leakdown test and me taking to Rich via email. Nothing was certain until Rich could take a look himself.

After he did his own leak he took the head of to be presented with this. Coal powered steam engine.



Upon taking the pistons out and cleaning the bores etc it was obvious the damage.
Rocker arms ruined. Cams ruined.





Oil pump scored.



Cylinder bores scored. Not too deep. Pistons scored again not too deep.







Crank journals slighly scored. This is piston 1 journal closest to the crank where the charger belt is tightened.


Upon closer inspection with engine out Rich noticed my oil cooler return line was trapped slightly.


My brother in laws garage changed the innovative engine mounts to soft OEM ones early last year and then must have accidentally trapped the line when lowering the engine. No one was to know and this would have had an impact of high rpm oil pressure hence the top end of the engine scored.
The oil burning was so severe i can only think the oil got low and did the bottom end damage. This must have happened when i didn't realize i was burning so much oil.
And why am i burning so much oil? Well ill hazard a guess it was 2 things, going from 3" exhaust and decat to 2.75" exhaust with sports cat and not getting a tune immediately causing lean conditions and a hot plug and also the time a ruind the map sensor trying to fix my sticking throttle and i flooded the engine washing the bores and diluting the oil.
It could be a number of these and all of these. Im not blaming anyone but just the turd situation.

Live and learn.



Rich gave me some options on going forward. I though long and hard and too the decision to sell the charger and make some money back and go high hp streetable N/A and plus save me the agony of belt slip and other charger related issues.

So
- the crank should polish up nicely. We await the machine shop.
- Pistons may polish up but going with 11.7:1 Wiseco pistons meaning ill put the 11.0:1 Arias pistons up for sale.
- Eagle rods are fine and reuseable.
- Need new rockers and going with Skunk2 Pro2 cams, supertech valve springs are salvageable. Going with Skunk2 valves and guides.
- Head will need fully dismantling and hot soaking.
- Block might polish up but new pistons will mean rebore to 88mm anyway.
- Cosmetic headgasket
- Skunk2 cam gears
- Skunk2 intake Manifold and 68mm Skunk2 pro throttle body.
- Keeping the DW550cc injectors and Hondata S300v3 ECU.
- CC Ultralite flywheel and OEM Accord Type R clutch.
- Type S intake and pipercross filter.

Should be a fun car again.




AS for the Supercharger setup. Would i recommend it? Hell yes.
HOWEVER.
Stick with the 6psi pulley setup. The 9psi pulley is great when its working however it causes to much belt slip which you are forever trying to tame, my engine bay is just caked in belt dust. Also 9psi adds so much heat that even water injection is difficult to tame. 6psi will be far far less.
Finally, the 9psi pulley spins the charger so fast it makes more resistance for the engine to overcome, thus the belt slip, you tighten the belt and in turn this puts pressure on the crank journal.
In hindsight i should have stuck with the 6psi setup and 68mm throttle body so it doesn't get sucked open by the charger vacuum.

Can't wait to put my supercharger on.

yowsers. how did you end up drawing so much oil into the combustion chambers? Some sort of breather issue perhaps? Is the inlet clean and clear? pistons aren't worn enough for it to get sucked in under vacuum, so it only came in from above (rings look good, no burning or oil marks on the way up the piston, only from the top down).

Do you still have the vtec oil pressure setup as per OE setup? That normally gives you a nice 'lower than normal oil pressure' warning before things get bad. The del sol did this on the drive home - first warning something was amiss, oil pump looked the same aswell. measured in spec believe it or not and it was reused begrudgingly because of budget, pressure still good afterwards...

Still onwards and upwards. Honda manual says you cant regrind the crank but have heard others get away with it.
