sacvwgolf 0 Posted September 6, 2009 Report Share Posted September 6, 2009 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:http://www.sipracingmailorder.com/servlet/the-92/Crank-Scraper-VW-VR6/DetailThe billet steel main caps:http://www.intengineering.com/Billet-steel-main-caps-p6902834-1-2.htmlWhat 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) Link to post Share on other sites
john555 0 Posted September 6, 2009 Report Share Posted September 6, 2009 how much power you after bud i dont have them or need them n im looking at making around 400bhp, i guess they wouldnt hurt but are probly over kill for most builds Link to post Share on other sites
sacvwgolf 0 Posted September 6, 2009 Author Report Share Posted September 6, 2009 thats the thing though...I don't have a target at the mo...but if forced to say it would prob be 500+. I want the engine to be reliable and bullet proof Link to post Share on other sites
john555 0 Posted September 6, 2009 Report Share Posted September 6, 2009 i wouldnt bother with the main caps but i guess for the price of the crank scraper it wouldnt hurt but im guessing thats more for helping high reving engineswhat you doing about a gear box Link to post Share on other sites
legvw 0 Posted September 6, 2009 Report Share Posted September 6, 2009 I thought that caps need to be matched to the block? So that they're all spot on tolerances.Don't really know bout the crank scrapper, never really heard of them. Link to post Share on other sites
john555 0 Posted September 6, 2009 Report Share Posted September 6, 2009 yer they say they need machining so gona be a cany expensie mod plus they state they are needed for 700bhp+ so i would just keep your cash for other bits Link to post Share on other sites
sacvwgolf 0 Posted September 6, 2009 Author Report Share Posted September 6, 2009 ah ok I just thought about it cause I reckon my orginal caps are knacked....Yeah its says they require line boring,As for the gearbox I'm gonna go 02M 4WD but I'm not too worried about that yet..just conectraiting on the engine at the mo Link to post Share on other sites
john555 0 Posted September 6, 2009 Report Share Posted September 6, 2009 the 02m swap isnt the most straight forward swap in the world both me and l5g vw are doing this swap, id get that done before worrying about building a 500 bhp engine, if they are knackered i would just buy a new engine a rebuild that Link to post Share on other sites
john555 0 Posted September 6, 2009 Report Share Posted September 6, 2009 forgot to ask what are you planning on running supercharger or turbo Link to post Share on other sites
sacvwgolf 0 Posted September 6, 2009 Author Report Share Posted September 6, 2009 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 etcYou 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?

john555 0 Posted September 6, 2009 Report Share Posted September 6, 2009 yer the fronts pretty easy but the rears a bit of a pain iv been doing my conversion for almost a year and im stil not doneiv got a rotrax supercharger that should be able to make around 500 with cams headwork pistons and rods Link to post Share on other sites
sacvwgolf 0 Posted September 7, 2009 Author Report Share Posted September 7, 2009 Yeah I'll defo be going rotex, I have a word with the people doing the machining to the block and see what they think Link to post Share on other sites
FishWick 21 Posted September 7, 2009 Report Share Posted September 7, 2009 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.htmI 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!

sacvwgolf 0 Posted September 7, 2009 Author Report Share Posted September 7, 2009 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. Link to post Share on other sites
FishWick 21 Posted September 7, 2009 Report Share Posted September 7, 2009 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 :-) Link to post Share on other sites
sacvwgolf 0 Posted September 7, 2009 Author Report Share Posted September 7, 2009 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. Link to post Share on other sites
FishWick 21 Posted September 7, 2009 Report Share Posted September 7, 2009 Cool, let me know what they come back with as I got round to speaking to them.Yep, should be available from the dealer but you can bet the HPA ones, imported, are cheaper than Audi ones, LOL! I will try and find out and let you know.... Link to post Share on other sites
sacvwgolf 0 Posted September 7, 2009 Author Report Share Posted September 7, 2009 Yep' date=' should be available from the dealer but you can bet the HPA ones, imported, are cheaper than Audi ones, LOL! [/quote']Yeah right lol Link to post Share on other sites
sacvwgolf 0 Posted September 18, 2009 Author Report Share Posted September 18, 2009 Hey Kev, whats your opinion on these:Coated rod bearinghttp://www.034motorsport.com/product_info.php?products_id=13975Coated main bearinghttp://www.034motorsport.com/product_info.php?cPath=28_85&products_id=952I never got a reply from HPAmotorsports, are these the same thing? Link to post Share on other sites
FishWick 21 Posted September 21, 2009 Report Share Posted September 21, 2009 Yeah I saw those! Much better priced than HPA's!I did a bit of asking around on the Vortex and it seems the stock VW rod and main bearings are perfectly fine unless pushing for mega power. The HPA ones are apparently just Audi RS4 ones as suspected, but with a 50% HPA tax on top! Link to post Share on other sites
sacvwgolf 0 Posted September 21, 2009 Author Report Share Posted September 21, 2009 I did think they were expensive, looking on the net the standard rod bearings are $73 and the coated they are $139 so thats £40 more for the coated ones, not too bad I'll have to find out how much the RS4 ones are from the dealership...
