Difference between l26 and l28

[richiep]

you need 90 stroke to go with the 91 bore to get to 3.4.

Yeah, I said 86+ as that is where things start to get extreme in terms of crank treatments. Some of the big Japanese and also Rebello and PMC builds have used modified RB cranks rather than LD-spec bases to work from.

As Alan said, it’s also the level of build that affects everything else - head, induction, exhaust, diff, etc. That goes for all stroker versions imo - a “poverty spec” 3.1 as usually touted historically on US forums (L28 with 89mm bore, LD crank, L24 rods, Ka24E flat top truck pistons) can be outperformed by a properly executed L28.

I think if we look at HSCC laptimes a 500bhp hybrid or the largest bolt on 'cheque book special' tend to be out performed around a circuit by a 2.4ltr carb snorting through twin SU's.

So now you have seen the error of your ways, I will sacrifice my self and take one for club by offering you a swap: my superior SUs for those rubbish OERs you have on the shelf!!!
