Equally engines have nearly identical exhaust cams. On the other hand the Blacktop has 0.23mm greater lift on the consumption. The cams may be swapped amongst the engines In case the VVT cam equipment is likewise swapped, but there can be no stage as both cams are pretty much similar so there would be no authentic obtain. Blacktops cams even have an interesting aspect in that the base circle (lower facet) of every one of the cam lobes have been machined these kinds of that they have only a small ridge for just a friction floor.
The Silvertop con-rods are extremely solidly built and with bolts weigh in at 506 grams Every single (without bearings). The Blacktop was fitted with thinner, lighter and weaker rods which can be 485 grams Every. Both equally are conveniently interchangeable and use the same fasteners for the primary bearing cap, therefore the ARP fastener enhance suits both equally as does an entire set of billet aftermarket rods.

16v might be easier then 20v, the hardest element can be electrical aspect of matters for both conversion with out 16v JDM looms
To adapt from 16v to 20v extractor flanges the most common way might be to increase the flange outwards on the two Serious edges with the same product and re-drill the flange. Another significantly less preferable selection might be to shave the outer edges with the flange after which you can use substantial washers to carry the flange in position Together with the outer bolts.

rice86 is on The cash. greatest wager is wait for somebody to dump theirs or get one particular with it and offload the shell later on, conserve you time trying to find all of the components and moneys In the end
The blacktop has lighter internals which happen to be also weaker, but it is a bit more rapidly. No hurt if you're not doing any significant mods, but any pressured induction and you will be needing to uprate the blacktops internals.
