- DeatschWerks 740cc Side-Feed Injectors (set of 4)requiresWalbro GSS342 255lph In-Tank Pump740s lean out on the stock 130lph pump above ~300whp; a 255lph pump is the floor for any SR20 injector upgrade
- Injector Dynamics ID1050X (set of 4)requiresRadium Engineering Top-Feed Fuel Rail ConversionThe SR20DET's side-feed rail cannot physically accept top-feed ID1050X bodies — the Radium conversion rail is mandatory
- Injector Dynamics ID1050X (set of 4)requiresWalbro GSS342 255lph In-Tank Pump1050cc of injector is worthless if supply collapses; a 255lph pump minimum keeps rail pressure flat at high duty cycle
The registry
All 17 chassis →Nissan Skyline GT-R
The homologation special that ate Group A alive and got named Godzilla for it.
Toyota Supra RZ
An iron-block promise: the chassis is good, but the 2JZ underneath is immortal.
Mazda RX-7
Sequential twin turbos, 1,270 kg, and the rotary's last, finest hour.
Honda Civic Type R
The first red-badge Civic — 185 PS from 1.6 litres and nothing wasted.
Ask the mechanic
“I want 350whp from my SR20DET” returns a parts list with prices, install order, and the compatibility rules that make it work — answered from the graph, not a search index.
