4.3L NA stroker or 8.5 pistons w/FI?
I want to get an Idea of who's running what under the hood... I'm not looking to see who's car is faster, I'm just trying to get info on the most reliable power setup that will make a significant difference. Please feel free to reply with RWHP dyno numbers, and engine upgrade cost, etc. Please specify wether it's a DYI or a pro-install. I'm especially curious about the 4.3L NA stroker kit. Please specify miles since build.

Given the cost of stroking a motor, I'd just forget about that idea altogether. A well built motor with a well matched turbo will make more power per dollar spent then stroker motor with or without FI.
I'd really consider the amount of power you are planning to make in this equation. For myself, I'd probably look at about 500HP so I'd probably opt to use 9.5 CR pistons and use reasonable boost levels from a turbo(s), so I can retain good off-boost response, power, and drivability.

You drive a 240SX with 5.5lbs boost, right? Did you ever raise the boost or are you still running 5.5?

I am going with SGP ulitmate short block with my greddy tt. It should be good for 500-530rwhp.

Yeah, 20k to 50k is a lot of cash.
Scratch THAT idea. I'll look into this SGP short block. I am by no means trying to run 500rwhp, I'm just trying to figure out a way to build a reliable FI setup, is it as easy as throwing in 8.5 pistons and slapping on & tuning a turbo kit? Anyone here running this setup?

This is what I am going with....look at my sig for the tt and extras. This would be a very reliable motor if you want less than 500rwhp. You will have to either send them your block or buy another one and send it to them. SGP does not have any blocks right now. If you go this route all you need to do is have a knowledgeable shop take out your block, ship it to SGP, and then have your shop install your TT kit on the motor while it is out and drop it in. The labor with tunning should be less than $2000 and that is on the high side. A good price would be $1400-$1700 for the install and another $300-$500 on tunning.
My motor is coming out today and should be at SGP by the end of the week
Ultimate short block: $3900
Block oil passages cleaned
Block redecked
Block Bored and Honed using a Torque Plate
Crank balanced
Crank journals polished
New Main and Rod bearings w/ceramic coating
Pauter Rods
ARP Rod Bolts
CP Pistons .020 over(8.5:1 or 11.5:1)
*Ceramic coating on Pistons
*ARP Main Studs

This is the email Kyle sent me. Give call a call and tell from Jorge from Carnival sent you. Tel: (281) 444-9195
I do not have any short blocks in stock at the moment. I could get your block done in about 3-4 weeks after I receive it. The block will be good for 700 Rwhp but with the mods that you have now you will top out at about 475 Rwhp because of the injectors. The block will bolt right in to what you have now. The only thing you will need to do is get your Emanage retuned.
With 550cc injectors you will be good for about 500-600Rwhp. If you do head work and cams you should be able to get over 550Rwhp but if you do just the block you will be limited to about 500-525 Rwhp.
