I have a 92 SC300 With a japanese 2JZ-GTE with a T4 Holset turbo that I was told is the size of a T88. It made 402 WHP on about 13 psi. I want to make 600-700 on pump but I dont really want to go full standalone at this point unless I need to. What do you guys think I should use for tuning and fuel system? SAFC, FIC, Tuned ECU?

First issue is you're not going to be able to make 600-700 on pump gas without going full standalone...

Honestly, I wouldn't even begin to consider pushing that much fuel (600-700 WHP worth) without a standalone AND a pro tune. I just don't understand why you'd want to cut that corner at the same time you're working your engine that hard.

Thats why I am asking these questions. With my last build 99 trans am f1a 408 i was pushing 8xx WHP on a stock ecu tuned so I'm seeing what the limits are with this setup.

Engine management is probably the most important factor when shooting for high horses.... no sense in pushing the limit if other resources are available.

I know I'm just debating if it's worth putting all the money in it or not I may be content with just like 600 who and I hear that people do that with a safc. Is that not safe?

Can it work? Yes it can. I just can't say for how long or if it will cause any issues.

Would I go that route? No. It's just risky when you start boosting a lot of psi into your motor and not have control of everything that goes into it. Not only fuel and air. With a standalone you will be able to correct timing and so on. So your best bet would be a standalone... but if budget is a factor, well just keep the boost low for a while and when you can spring for it. Good luck
