The rods are both the same, I'm pretty sure. The pistons are different. So order accordingly.

If you build your motor for boost, there is no problem whatsoever with you running a header and going N/A. There are many guys on here that run their cars like that to break them in without worries of boosting and blowing stuff up. Just make sure you tune the car for running N/A, or you will risk dumping too much fuel, and thinning out your oil.

As far as variations on the T3/T4 Hybrid, there are many. You can max a small one out with like 5psi if you get a dinky one. Or it will take your KA about 7,500rpm's to spool a bigger one. So Trim, and AR will be something to look into.

Not sure on what you want to do. I know people say read the sticky's, but the ones at the top of the page will make your brain explode with information. Read up, and ask questions. I'm just not sure I answered all of yours. Just the best I could do.

As far as tuning what are your thoughts on the SAFC2? I have been looking around at those as well. Is there a way to hook up an exterior screen to one? I have a spair LCD screen I want to put in the dash and I'd like it to be either a full computer or have a way to hook it up together. If not What would you suggest I go with. I have the computer most of the way built already and I'm going to have it mounted in place of the glovebox I've also looked into the carputer's that they have that slide in where your cd player goes but idk if I like them or not.

Either route I'd still like to be able to tune my car from right inside of it.

I Would like to also look into an intercooler setup thats not e-bay junk. What are good brand's I'm wanting something around 2-3" thick by around 20-24" long and 12-15" high.... What would be a decent one to start out with. Do they come with mounting hardware or do you have to fab that up.

Also I've seen that most guys pull the inner bumper support out when they run an intercooler. Do you have to remove it or can you just cut part of it out.... Any one know what size intercooler fits best with the bumper core support?

How much boost can the stock sohc ka rods and piston's handle? What about the valves?

Theres tons of choices now for a turbo. Borg Warner is making the best turbos right now(simply true). You might want to do some research on the BW S series with the extended tip. They are blowing Garrett's GT-R series away. They are in the 900-1400 dollar range however. It really depends on your goals for the car. The Garrett t3/t4 is still a sweet option, starting new at about 450-600. I ran a 50 trim .63 ar t3/t4 for a while and absolutely loved it. It can flow enough air for 450 hp, and provides quick spool which makes it a blast to drive on the road. If you take care of the turbo, it will last you forever. If you want an instant boost car, use a .48 housing on the t3/t4 and its good till 400 hp.

IMO, a SAFC is not even an option anymore for tuning. They are so limited, and have resulted in so many blown motors. They are a great tool for fine tuning a ECU/Rom tune but thats about it. I would recommend going with an E-Mance ecu for the price. Or if you want to go all out go with Enthalpy, hes been in this business forever. 125 for an Emance ECU, and 500 for an Enthalpy. My Enthalpy held spikes of up to 23 psi with no signs of detonation on pump gas. The highest HP stock block build was run with an Enthalpy ecu, and it was run at 30 psi.

Since you want to get into tuning, i would recommend the ECU tune + SAFC/Wideband. This will allow you to learn how to tune the easiest way possible. With your laptop idea, i would say you should look into a Zeitronix wideband. They have IMO the best wideband unit out there right now if you dont mind using a laptop to see your engines data.

Ebay IC's are fine, people run them all the time and they never give anyone any problems. You might have a slightly larger pressure drop across an Ebay core than you would a high dollar IC, but the difference is like .5-2 psi. You can always crank the boost up just a little to compensate.

I think pulling the bumper support out for an intercooler install is about the dumbest thing you can do when your going turbo. Its not hard at all to keep the bumper support, that thing can save your life, and your car. Here is a writeup i did on keeping the bumper support while installing a IC.

I dont know how much the SOHC can handle safely, but i can say that 350 whp is a safe limit for the DOHC. Its all in the tune man. You dont have to worry about your valves being able to handle boost, they are gona do their thing regardless of boost levels.
