FH6 Honda Integra Type R Tuning — 2023 Type S Setup

The Integra Type S is the modern answer to the question “what should Honda build after the S2000?” Where the S2000 was a high-revving naturally aspirated roadster, the Integra Type S is a turbocharged liftback with practical cargo space, comfortable suspension, and the same Honda engineering philosophy. Forza Horizon 6 includes the 2023 model as the Integra Type R. This guide covers the FF tuning philosophy, the understeer fixes that make the platform work, and the build paths for touge time attack and road racing.

1. The Integra Type S Philosophy — Refined FF for the Real World

The Integra Type S is positioned between the Civic Si and the Civic Type R. It’s more powerful and more focused than the Civic Si (200 hp vs 200 hp, but with the Type S treatment), but less extreme than the Civic Type R (315 hp, track-focused suspension, aggressive aero). The Integra is the most usable performance Honda — comfortable enough for daily driving, capable enough for track days, and practical enough to be the only car in a garage.

What this means for tuning: the Integra rewards setup discipline over peak power. The L15B7 engine has good headroom up to ~320 hp, but the platform’s strength is its balance, not its top-end. Players who try to make the Integra into a 400 hp monster lose the platform’s defining characteristic. The Integra is the Honda for drivers who want refinement, not raw performance.

2. The Engine — L15B7 1.5L Turbo

The L15B7 is Honda’s modern small-displacement turbo four. Three characteristics define it:

• Direct injection + turbo — the L15B7 uses direct fuel injection and a small turbocharger to produce 200 hp from 1.5L. The turbo spools quickly but runs out of breath above 6,500 rpm.
• VTEC on intake only — unlike the K20C1 in the Civic Type R, the L15B7 only uses VTEC on the intake camshaft. The power delivery is still engaging but less dramatic than the K-series.
• Strong aftermarket — the L15B7 shares its basic architecture with the Civic Si and Civic Type R, so most turbo and intake upgrades work across all three platforms.

For tuning, the L15B7 is happiest in the 250-300 hp range. Beyond 300 hp, the stock fuel injectors and turbo run out of headroom. The Integra is not a 1,000 hp platform — it’s a refined, balanced liftback, not a tuner special. Stop at Stage 2 engine tune + race exhaust + upgraded turbo.

3. The FF Understeer Problem — Integra-Specific Fixes

Like all FF Hondas, the Integra’s natural state is understeer. The Integra’s liftback rear is slightly heavier than the Civic Type R’s hatchback (due to the longer roofline and cargo area), which means the understeer is slightly more pronounced. The fix is the same as the Civic Type R: balance the chassis without inducing lift-off oversteer.

Anti-Roll Bars — Softer Front, Stiffer Rear

• Stiffer rear ARB — the Integra’s liftback weight distribution benefits even more than the Civic Type R from a stiffer rear ARB. Start at front 13 / rear 19 (stiffer than Civic Type R’s 14/18).
• Soften front ARB — let the front suspension move more freely. The Integra’s stock front ARB is conservative; softening it by 1-2 clicks improves mid-corner grip.

Camber and Toe

• Front camber — -2.5° for road racing, -2.0° for touge. The Integra’s stock front camber is conservative.
• Rear camber — -2.0° to -2.5°. More rear camber helps the rear tires grip under braking, which prevents lift-off oversteer.
• Front toe — 0.04° (slight toe-in). Toe-in gives front-tire stability on straight-line braking.
• Rear toe — 0.10° (toe-in). The Integra’s multi-link rear suspension responds well to small amounts of rear toe-in.

Ride Height — Lower Front More Than Rear

• Front — 12.5 cm. Lower the front more than the rear to transfer aero load forward and reduce high-speed understeer.
• Rear — 14.0 cm. The Integra’s liftback rear benefits from a slightly higher ride height to maintain cargo-area access and prevent scraping.

4. The Touge / Daily Build (A 800 Class)

The touge / daily build is the Integra Type S’s strongest use case. The liftback practicality, the compliant suspension, and the refined chassis make it the most usable performance Honda in the game. This build is for Horizon Japan touge events, the Akina Pass hidden location, and Hokkaido mountain roads.

Engine — Light Forced Induction

• Intake & exhaust — race intake + race exhaust. The L15B7 responds well to better breathing; the turbo spool is faster and the top-end power is higher.
• Forced induction — keep stock turbo. The L15B7 stock turbo is well-matched to A 800; the upgraded turbo pushes the engine past 320 hp, which the chassis can’t put down.
• Transmission — race transmission for closer gear ratios. The 6-speed manual’s gearing is wide; race gears keep the engine in the VTEC range.

Suspension (Touge Balanced)

• Springs — sport springs. 145 kgf/mm F / 155 kgf/mm R. The Integra’s liftback rear benefits from softer rear springs for cargo loading.
• Anti-roll bars — softer front / stiffer rear. 13 F / 19 R.
• Camber — -2.0° F / -2.0° R.
• Toe — front 0.04° (toe-in), rear 0.10° (toe-in).
• Damping — bump 6.5 F / 6.5 R, rebound 5.5 F / 5.5 R.
• Ride height — 12.5 F / 14.0 R cm.

Tires, Weight, Aero

• Tires — Sport tires, 245 F / 245 R. Sport tires last longer than Semi-Slick and provide enough grip for sustained mountain passes.
• Weight reduction — Stage 1. The Integra is light for a liftback (~1,400 kg); Stage 1 takes it under 1,350 kg, which is meaningful for FF handling.
• Aero — keep the stock rear spoiler + small front splitter. The Integra’s stock aero is well-designed; don’t add aggressive downforce or you upset the platform’s balance.

5. The Road Racing Build (A 800 Class)

The road racing build is the Integra’s weaker discipline (the Civic Type R wins here), but the Integra’s compliant chassis and predictable behavior make it competitive at A-class. Use this build for circuit events and Horizon Sprint races where driver consistency matters more than peak lap time.

Circuit-Specific Changes

• Springs — race springs. 160 kgf/mm F / 170 kgf/mm R.
• Anti-roll bars — softer front / stiffer rear, more aggressive than touge. 13 F / 20 R.
• Camber — -2.5° F / -2.0° R.
• Ride height — 12.0 F / 13.5 R cm.
• Tires — Semi-Slick, 265 F / 265 R. The Integra runs wider tires than most liftbacks; 265 front and rear gives the grip needed to put power down.
• Weight reduction — Stage 2. The liftback rear weight benefits from more aggressive weight reduction for circuit driving.

6. Common Integra Type R Tuning Mistakes

1. Treating it like a Civic Type R. The Integra is the more compliant platform. Race springs on the Integra produce the same snap-oversteer problems they do on the Civic Type R, but the Integra’s softer chassis amplifies them. Use sport springs for touge, race springs only for smooth circuits.
2. Adding aggressive aero to fix understeer. More rear downforce loads the rear tires, which sounds good but actually pushes the front lighter and increases understeer. Add front splitter, not rear wing.
3. Stiffening the front anti-roll bar. Stiffer front ARB feels responsive but reduces front grip in mid-corner. The fix is to soften front and stiffen rear — counterintuitive but correct.
4. Trying to drift the Integra. The Integra is FWD. Drifting in FH6 requires RWD or AWD. Use a Silvia, 350Z, or S2000 for drift.
5. Pushing the L15B7 past 320 hp. Beyond 320 hp, the stock fuel system and turbo can’t keep up. The Integra is a balanced platform, not a power platform. Stop at Stage 2 engine tune + race exhaust + race intake.
