Hi, this is my first post so I don't know if this is the right place to post this but I have a b18 swapped del sol and I'm looking to make around 300-350hp on it. This is my first build(my brothers getting me into cars) so I'm coming here to see if I can get to 350 with stock internals or not, and if not how much engine work is really necessary to hit that.
This is what I have so far, if anyone can spare any advice or anything more I'll need please help lmao. thanks!
arp Headstuds
Intake Mani
skunk2 headers
T3 Turbo kit
TiAL 38mm Wastegate
TiAL 50mm BOV
550cc Injectors
act clutch
hondata s300

 

You would be wise to have more injector, 750s or 1000s. Ngk bkre spark plugs (box number 4644 i believe). Ptp turbo blanket. Hawk HP+ pad with steel braided brake lines.

If your engine isnt apart yet. Just keep the arp headstuds for when you need to do the headgasket

 

Thanks for the advice! so you don't think I'll need forged internals? I plan to drive the car pretty often.

 

350hp on stock B18B1 internals….good luck. At least upgrade the pistons and rods along with new bearings and gaskets/seals.
Skunk2 headers ??

 

I would do rods and pistons as NVturbo has suggested.
