now before I go power crazy and finish my monster I want to be able to run it at a relative boost level and make sure my complete setup is working just fine.

I want to use stock injectors and maf with stock computer. how-ever I am using a full-race manifold with t3/t04e turbo (good to 450hp).

Now if I set the external wastegate to 5lbs would I be relatively safe to run my car for a few weeks make sure everything is fine on as stock setup as possible with the stock ecu and maf?

Also- I do not have an sr20 maf does the one from the ka work in place of the sr without a retune.

btw,
I do have 730cc injectors and a retuned ecu for the z32 maf. But since I have never run this particular setup I think it would be a good idea to keep it as simple as possible before adding too many variables.

Thanks Andrew.

Running a turbo setup on a NA tuned Ecu is a VERY bad idea. It'd be a much better idea to put the injectors, Z32 MAF, and retuned ecu on the car and run it NA to make sure it runs fine, and then put on the turbo.

I ran my car with 370cc injectors and JWT ecu tuned for boost for 4 months before I actually put the turbo on. Ran perfectly fine.

oops sorry for the confusion, the engine I have is an sr20det w/upgraded turbo and manifold and exhaust.

in a s13 chassis, I should have gave more info.
