Turbo Kit for Hyundai Elantra Tiburon (1996-2001) 1.8L

Complete intercooled stainless T3/T4 turbo package for 1996–2001 Hyundai Elantra and Tiburon with the 1.8L DOHC four. It pairs a TIG-welded 321 stainless tubular T3 manifold with a hybrid T3/T4 turbo, 35mm external wastegate with positioning adapter and dump tube, stainless downpipe, front-mount intercooler, boost controller, blow-off valve, turbo timer and fuel-system parts in one box. Most installs keep A/C and power steering, and it works with manual or automatic transmissions. Expect about 50–100 hp over stock at a conservative 8 psi with a proper tune. The 485+ hp figure is the hardware's ceiling at 25+ psi with a built engine, fueling and supporting mods, not a dyno result for a stock car. Engine family reference: G4GM.

Exact Fitment — Hyundai

• 1996–2000 Elantra with the 1.8L DOHC four
• 1997–1998 Tiburon with the US-market 1.8L DOHC four (US Tiburon 1.8L was only those two years; most US Tiburons are 2.0L — use the 2.0L Tiburon kit for those)
• Not for 2.0L Tiburon / Elantra engines
• Not for later 2.0 Gamma / Nu Elantra engines
• Intercooler piping is universal and needs cutting and fitting per chassis

Not Included

• Exhaust beyond the downpipe
• Larger injectors, fuel pump and ECU tune (required)
• Clutch upgrade, boost gauge and wideband
• Oil-pan return bung if your setup needs one

Installation Notes

• Professional installation strongly recommended. Expect cutting and fitting of the universal piping and test-fitting the downpipe
• Oil return must drain by gravity; prime the turbo with oil before first start and check for leaks
• Blow-off valve flanges are installed at your discretion
• Keep boost at about 8 psi until fuel and tune are upgraded, and let the turbo timer handle cool-down

FAQs

Does this fit my 1999–2001 US Tiburon? Only if it has the rare 1.8L. Most US Tiburons in those years are 2.0L — use the 2.0L Tiburon kit instead.

How much power will it make? About 50–100 hp over stock at 8 psi on a healthy stock engine with a proper tune. 485+ hp is the hardware ceiling with a built engine and full supporting mods.

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

Manual or automatic? Fits either when the engine matches.

Is it plug-and-play? No. You still need injectors, a fuel pump, an ECU tune and some pipe fitting.
