Bigger turbo on an SR20DET is a must after you raise the boost to like 14 psi. So for cost i'd say get an Sr20 which is in my eventual plans. Also i have heard KA-T's don't last very long, so reliability is an issue.

The only one that a number of tuners have told in some instances would be harder than a RB swap is the VG30DET, or TT. which just isnt possible without a really steep wallet, and ALOT of time. Ive asked Dauntless about this very thing. As far as the VG30ET most shops have all pretty much said the same thing, minor mod work, a bunch of tuning, and trial and error. When being able to see stock 200hp and 227 ft/lb on the torque side..is actually pretty damn decent. Especially for close to $1000 less.
And the question about the possible power value of the KA24 engine was how much could i look at realistically before going turbo. Some have said possibly 200-215, depending on the parts, and depending on the current state of the engine. In the end being totally rebuilt would give the best results. Taken into case..i wasnt trying to be flamed.. simply asking for some feedback from owners that have done the KA rebuild. Not a noob by anymeans but its always a good thing to hear out horror stories and lessons before making a final decision. Sleeper or not.. Noone in Northern Cali i -know- of has a VG30ET. Especially when in this case it is pretty cost effective when compared to a SR Clip + install (if i didnt decide to do it at our garage) and still be capable of Much more power and boosting levels in the end.
If you lower your compression with a thicker head gasket you'll be able to run as much boost as any SR.

C-Kwik wrote:Not necessarily. Modern heads are designed with quenchpads on the outer edge of the combustion area. The space in this area at top dead center is quite small. Small enough that most of the mixture can be pushed towards the middle of the combustion chamber. This aids in preventing detonation, and helps to lessen the chance of damage when there is detonation. The mixture that is still trapped in this area tends not to burn at TDC since the mixture sits right up against the cooler(relative) metal of the heads and piston. A thicker headgasket will increase this space and may take away some of the quenching effects of the cylinder head.
