What internals would I need?

Hi there guys so I just as of last night instead of being lazy like I have been for the last 2 years with my old motor, started to pull it down, didn't get a great deal off it but I made a start.

Anyhow the question on hand that I have for the more senior members of this forum is if I put bigger turbos on the engine in the rebuild process what internal upgrades would be advised, I don't exactly want to make the highest hp car out there but preferably make somewhere the mark of around 400-500rwhp.

Also with that said, would it be advised to upgrade injectors and fuel pump to cope with this at the same time or would the stock ones be able to hold up to the job?

Again with another question, I'm not sure if the motor that was in the car at the time was an automatic one as before I had purchased the car it had been converted to a manual, what I'm really asking here is if there are any major differences with the internals of a manual or auto engine?

Now to the final part of it all, what turbos would be recommended in your opinions to make this gain possible, they don't have to be massive but just something other then the stock ones, as I presume there are a lot of you out there that have done this conversion I'd like to possibly find the most hassle free option with minimal modification so it all fits back into the cars engine bay with ease.

Any information would be greatly appreciated as this would be my first time ever doing something like this, my first turbo car is my current 300zx and I'd just like to keep it but make it that little bit stronger all round.

Thanks, David.

 

Lots of options
Also allow cash for ECU, tuning, labour, machining ect

 

Get the crank rebalanced and new bearings as stated.
Wiseco pistons and eagle rods
Look for a basic rebuild kit from CZP or Z1 shouldn't set you back to much.

You don't need to worry about the valves and porting etc for that level.
Gt2560 turbos -gt2860RS will get you comfortably to that zone. You'll be looking at nismo injectors or JECS or anything in general (500cc+) and a aftermarket pump/ maybe regulator

All depends how much you want to spend

Wiseco piston
Eagle rods
Rebalanced crank
Bearings
Cleaned up heads
Mild porting
Manual cams
2860 turbos
555 nismo injectors
255 or 400 walbro pump
18-20psi should see 400-450rwhp I'd hope

 

Think I have the machining part and labor part covered as uncle is a motor engineer but just putting out these questions for myself so im aware of what I need and what I need to do, as for the difference with the cams.

Is there any noticible way of telling the difference of whether it was a auto or manual engine just by looking at them? I do suppose though if I get bigger ones this would make no difference anyhow?

This build may take me some time I'm hoping not too long but I'm not the richest person out there so I'm guessing a year or two.

Also I do have a TF035Hm turbo apparently off a forester sitting around at the moment, would it be beneficial to just get another one of those or just do as suggested above?

Thanks again.
