Crank scraper and billet steel main caps for vr6. Opinions please :)


Recommended Posts

Hi Guys, I am in the middle of budgeting/planning my vr6 rebuild and when I was working out what was needed/doing research I came across these two things:

The Crank scraper:

The billet steel main caps:

What do you think of these two, are they any good/worth it?

Any input would be great.

Scott :)

P.S the engine is being built for alot of power (Forced induction)

plan is to supercharge it....not a fan of turbos. I would love to try and twin supercharge it but thats something for the futuar (sp?).

I know abit about the 02m swap...cutting and repostioning of the gearbox mount, C2 bracket mount etc

You think its not worth rebuilding the block I have, I doubt the caps are knacked, but if they were, then is it better to start with a newish block than to buy the steel billet caps and get them machined to fit?

I whole heartedly support and recommend over engineering and those billet caps look nice and nicely priced too.

You might want to consider these rod bearings too - http://www.hpamotorsports.com/bearings.htm

I would add that if you're going Supercharger, you don't need to go quite as military with the strengthening due to the way the boost is delivered. Turbos definitely need all this, although many people run around with nothing more than spacer plates and do OK. But with forced induction VR6s, it's not a caseof if it will break, but WHEN it will break, and that goes for both methods :-)

Build it to last and it'll be fine.

Also bear in mind over 400whp from these engines in a FWD application is practically unusable on the road, LOL!

I saw you mention them bearings in another post, they look good but I bit pricey although I could prob make some money back selling the rod bolts as most conrods come with the arp bolts anyway. I'll have to see what my budget is and try to include them. I'm a fan of overengineering aswell :).

Lol yeah I was planning on going to around 250 hp and get the engine set up/running pefectly and then go to 4WD and then go 400/500 + in the furtura (I really must learn how to spell that word lol).

Looks like I going to have to try and include all three things in the ever inceasing budget. I've already ruled out getting the crankshaft knife edged.

Future :-)

Futura sounds like some flashy concept car :-)

I have it on good authority those bearings are actually standard RS4 ones but I'm not sure if they are RS4 as in 4.2 V8, or RS4 as in the old 2.78 Biturbo engine! Need to find out and come back to you but they are supposed to be very strong.

When I say unusable, it's mainly just in the wet. Providing you have good tyres, a diff and good suspension geometry, it's not bad in the dry. Just have to put up with loads of torque steer :-)

Thanks, I've just emailed them to see if they'll do them by themselves.

If they are RS4 or similar does that mean they can be bought from the dealers? If you can comfirm what they are and what engine they are from I'll go to the dealers and get a price :) if they are avaible.
