Advice for future mods

I have a turboed N/A block and it's running good. I'm only pushing about 8PSI right now.

Now in the future, when I have money, I'm wanting to port it out and such.
Should I port the N/A block or just buy a t2 block and mod it.

I honesty like the N/A block being turboed. The power band starts sooner. But that's neither here nor there! So I kind of want to keep the N/A base.

thanks for your advice in advance.

Port it and go to a standalone.

See what a stock port n/a motor can do. Put a bigger turbo on there with some race gas and proper engine management.

It will do quite a lot actually. The stock 6 port engine has way more port area then even many ported TII engines, so it's not like port size is going to hold you back.

But I'm guessing that a custom intake manifold would be more efficient in using the extra port than a ground out t2 manifold!

Also as far as Standalones, would an Rtek 2.0 be enough or would it be better to have a Haltech or some such system? Because really I need to control the spark timing just as much if not more than the fuel mixtures. Right?

In that case, could I stick to a piggy back and get an MSD box?

The only experience I have with the RTek is negative. But it was not the RTek's fault, but that of the owner (not me). However my firm belief is that if you are going to go standalone, you might as well do it RIGHT and start with a modern ECU (Haltech, Microtech, Megasquirt) with a NEW harness right from the start.

If you can make a custom intake, then building a custom lower to meet the TII upper with the 6 port block is certainly a good way to go.

If you are planning to make power past the high 200s, then piggybacks rapidly become useless. You need timing control...

One more thing. Is there a formula or number or something in order to figure out how much to retard the timing per PSI?

2 degrees per PSI over about 7-8PSI.
