yeah, the ca18s with intake cam-only swap ran T28s.... and the impressive torque curves got my attention
Probably their intent. Fatter tq band, from a quicker spool makes sense. Perfect daily driver
bandaid... compromise...? Like water/meth escorts many into the 'monster zone'. Whatever it takes, eh.
For comparison, here's two more stock head stock cam stock valve 1.8s

500hp bone stock 1.8 escort relatively low 370 tq, perhaps from bigaz 62 slow spool. Not a particularly efficient setup either
The miata is another story. Good spooling smaller 50 trim t3/t4 @ 500hp, mid 400s tq on 93 pump + w/m inj
Pretty much same recipee as DSM & toyota 1.8 above - short runner intake & header. Fresh valvesprings with 10psi additional pressure
Built bottom end because BP rods r a timebomb (bend) ~350ish ? once u 'load' em up.
In another thread, regrind intake cam added 38hp, then 24hp more from exhaust cam swap
I believe he upgraded to 35R and lovin it (just like boost_boy has been sayin -lol)
Quite a few 5557 n 5558 ca18 and miata 1.8 street monster combos out there to study/copy also.
cool one here: http://www.roadkill.com/fuel-seeking-st ... zda-miata/
