Are you chasing 300hp at the wheels or flywheel?

What will the car predominantly be used for?

What sort of compromises in power delivery can you live with?

What's your budget?

40thou over, would only go 20thou .5 over just in case you need to hone bore later.

Hi guys whats the standard bore size off the ca18det.Ok its 83mm if i go 84 mm how many thou is that over.

mcdat, just get Nissan CA18DET Rebuild Kit from spoolimports.com + main and head arp bolts. Drop in pon tomei cams with race valve springs. Dream ca18det would be lewisengines 2.3l stroker kit :)) Turbo options would be 2871 with .63 rear or if you have the money 3071 .63 t3 twin scroll + 6 boost manifold

A good motor builder should be telling u what he should do! You can get kits from us full forged stuff for 1500 or so! And a gt2871r will be good for 300-350 next step is 2876 but a little more lag but depends again on manifold and flow, a manifold like 6boost will make spool faster ect!

Hi guys im in the process off getting a ca18det built,just wondering can anyone tell what needs to be done to achieve 300hp also what size turbo should i put on it,was thinking 2871r.Need help so i can express what i want done to the builder,all i have said to him is build me a 300hp engine with scope for more hp if i want it.
