Turbo Kit for Honda Civic CRX Del Sol D-Series (1988-2000) 1.5L 1.6L D15 D16

Complete T3/T4 turbo kit for 1988–2000 Honda Civic, 1988–1991 CRX and 1993–1997 Del Sol with the D15 or D16 D-Series SOHC engine (1.5L / 1.6L). Built around a polished 321 stainless tubular manifold, a hybrid T3/T4 turbo, front-mount intercooler, stainless downpipe, 35mm external wastegate, oil cooler kit and a full set of supporting hardware. This kit is for D-Series engines only — not for B-Series (B16/B18/B20) cars. A tune and fueling upgrades are required.

Turbocharger & Manifold Specs

• Turbo: T3/T4 hybrid, wet-float bearings, balanced
• Compressor: .57 trim, .50 A/R housing, 3" inlet, 2" outlet
• Turbine: .63 A/R housing, T3 inlet flange
• Oil inlet: 1/8" NPT

• About +100 hp on a healthy stock engine at 8 psi with a proper tune; 450–485+ hp is the hardware ceiling at 25+ psi with a built engine and supporting mods — not a dyno result

Exact Fitment — Honda Civic, CRX & Del Sol

• 1988–1991 Honda Civic DX, LX, EX, Si, HF, Wagon (D15 / D16)
• 1992–1995 Honda Civic DX, LX, CX, EX, Si (D15 / D16)
• 1996–2000 Honda Civic DX, LX, CX, EX, HF (D16)
• 1988–1991 Honda CRX DX, HF, Si (D15 / D16)
• 1993–1995 Honda Del Sol S (D15) and Si (D16)
• 1996–1997 Honda Del Sol S (D15) and Si (D16)
• Requires the D15 or D16 SOHC engine. Not for B-Series swapped cars, the 1999–2000 Civic Si (B16) or the 1994–1997 Del Sol VTEC (B16).
• Manual or automatic transmission
• Intercooler piping is universal 2.5" aluminum and may need light trimming to fit; verify routing around the radiator, bumper support and A/C lines before final install

Not Included

• Exhaust beyond the downpipe (mid-pipe / cat-back connection)
• Larger fuel injectors, fuel pump, and engine management/tune
• Oil-pan return bung/drain fitting welding
• Upgraded clutch, gauges (boost, AFR, oil pressure)

Installation Notes

• A proper tune with upgraded injectors and fuel pump is required — do not run boost on the stock calibration.
• The oil return must drain by gravity into the pan; most installs need a return bung added to the oil pan.
• Expect to adapt the downpipe to your exhaust and trim intercooler piping.
• Blow-off valve flanges can be installed at the installer's discretion.
• Use the turbo timer or idle 30–60 seconds after hard driving so the turbo can cool down.
• Stock D-Series pistons and rods have limits; keep boost low on a stock bottom end.
• Professional installation is recommended.

FAQs

Will this fit my Civic?
Yes if it has the factory D15 or D16 engine (1988–2000 DX, LX, CX, EX, HF and 88–95 Si). It is not for B-Series engines.

Does it fit a CRX or Del Sol?
Yes. It fits 1988–1991 CRX DX, HF and Si, and 1993–1997 Del Sol S and Si with the D15/D16 engine. The Del Sol VTEC uses a B16 and is not covered.

How much power will it make?
Around 100 hp over stock at 8 psi on a healthy stock engine with a proper tune. Higher numbers need a built engine, fueling and more boost.

Does it include a downpipe?
Yes, a stainless 2.5" downpipe is included. You will need to connect it to your exhaust.

Does it work with an automatic?
Yes. It fits manual and automatic Civic, CRX and Del Sol models with the D15/D16 engine.

Can I keep A/C and power steering?
Most installs keep A/C and power steering; confirm clearance during the mock-up.

Is it plug and play?
No. It needs a tune, fuel upgrades, an oil-pan return fitting and some fabrication.
