Gerg_R31 Posted January 21, 2009 Share Posted January 21, 2009 what would you charge for the rb30 stroker crank and rods? you mentioned making forgies with it, but me and i notced a few others have gone the N/A path so just wondering if you were making non forged pistons to suit? are you going to make these reguarly or made to order or just the 1 off batch?

Spoolup Posted January 21, 2009 Share Posted January 21, 2009 (edited) It will be a kit, custom crank, custom rods and custom pistons. I wont be making any N/A pistons - sorry Edited January 21, 2009 by Spoolup Link to comment https://www.sau.com.au/forums/topic/212607-crank-strength-and-upgrading-options/page/7/#findComment-4382387 Share on other sites More sharing options...
Shaun O Posted January 21, 2009 Share Posted January 21, 2009 Hey Spoolup, have you got a better idea of price now on the full kit? Whattya reckon that should rev to?

Gerg_R31 Posted January 22, 2009 Share Posted January 22, 2009 any reason to why your not making this kit with a non forged piston? (not everyone wants to go the forced induction path) can the kit be bought without the pistons? whats the height difference between the normal rb30 piston and the piston for the 3.3? i've been told there are pistons that have a shorter skirt that will suit the rb30de im building, cant remember the part number but what are the chances of them suiting? do you balance the cranks? will the 3.3 crank have knife edging or standard counter weights?

Spoolup Posted January 22, 2009 Share Posted January 22, 2009 (edited) Shaun O - around the $6500 - 7000 mark with the AUS dollar at its current rate. It should see 7500 - 8000 plus rpm depending on setup. Gerg R31 - The reason is that you are the only person who has mentioned it, so Im presuming demand is minimal especially due to the price involved. The other reason is that no one readily and easily makes cast pistons in short runs or one offs. I could easily make you a forged piston for an NA set up though. You would just have to spec the comp ratio you require. The length of the skirt has nothing to do with the comp ratio.

Gerg_R31 Posted January 23, 2009 Share Posted January 23, 2009 (edited) i just thought you may have designed pistons that were shorter to suit the stroker kit, if the over all height of the pistons dont change i might still be able to get the ones i had in mind, though i know forgies handle heat better im aiming at around 10.5:1 to 11:1 comp ratio so if you made me a piston the rb25de piston dome with valve releif would be fine with me plus i work at a machine shop so decking and other machine work and balancing etc is easily done are you making the kit pistons dome with valve releif? flat top? or dish? (i know alot of questions but more info may also bring more interest) Edited January 23, 2009 by Gerg_R31 Link to comment https://www.sau.com.au/forums/topic/212607-crank-strength-and-upgrading-options/page/7/#findComment-4385985 Share on other sites More sharing options...

Swiper the Fox Posted January 25, 2009 Share Posted January 25, 2009 ok, rips.what have you done with the oil pump issues on a 30 crank? you havent broke any? im sure that would be ok due to the lower rev range of the 30.

Dynamix Posted January 25, 2009 Share Posted January 25, 2009 im sure that would be ok due to the lower rev range of the 30. Well the rb26 in thier Z drag car is seeing 10,000 rpm with the tomei pump so i would think rob has something sorted... Spool, so you 3.4L kits will rev to 7500-8000rpm?

Spoolup Posted January 26, 2009 Share Posted January 26, 2009 We will have to wait and see - but similar setups with the 3.4L 2JZ ( near identical bore stroke ratio ) have gone 8000 plus easily enough Well the rb26 in thier Z drag car is seeing 10,000 rpm with the tomei pump so i would think rob has something sorted...Spool, so you 3.4L kits will rev to 7500-8000rpm?
