I remember reading a while ago that SARD made a 1 off 2j twin turbo manifold.

I wanted to change my twins to maybe like Nissan T25 OR T28 spec, to keep them reliable, have a decent linear boost and possibly make 400whp on decently low boost (higher boost= increased engine temps.

I ran a CT26 57 trim at 19psi and i made the same amount of HP on my stock CT12a's. The engine temp went up a **** ton and it just wasn't reliable.

Or can the center cartridge of the CT12A be replaced with that of the CT12

I like the twins, and their pretty linear power, but they aren't reliably rebuilt in the USA.

What engine temps are your seeing with the stock twins? Mine seem to really put out heat while road racing. I have an oil cooler, 3-row radiator, huge open bumper and front spliiter and was at 220F water and 260F+++ oil a month ago in 80 degree weather after a couple laps at 90%. I do like the twins too, but I don't think they work for prolonged racing. Especially when out of their efficiency range they will blow more heat. I run 17-18lbs on track at 10.5-11AFR

I guess it could be something messed up with my engine, but all the other engine readings are good.

Here's a link I found about upgrading the twins. I don't know anything about the guy who does the upgrades, so read up on the thread.
