A: Displacement is the cheapest torque there is. The extra 200cc lifts response and load-carrying grunt across the whole rev range, and raises the ceiling of what the platform can support with fuel and boost. Q: Is this a drop-in part? A: No. It requires a full engine build. Your engine builder should confirm bearing clearances, piston-to-head clearance and component selection for your combination. Q: Do I need different rods or pistons? A: Component selection depends on your build target – talk to your engine builder. We stock forged I-beam rods, genuine 110 pistons and ARP head studs to suit built 1KDs. Q: What's the lead time? A: Typically 1.5–3 weeks from order to dispatch. ✓ Added to cart! document.addEventListener('DOMContentLoaded', function() { const notification = document.getElementById('cart-notification'); const notificationText = document.getElementById('cart-notification-text'); function showNotification(msg) { notificationText.innerHTML = msg; notification.style.display = 'block'; notification.style.animation = 'slideIn 0.3s ease'; setTimeout(() => { notification.style.animation = 'slideOut 0.3s ease'; setTimeout(() => notification.style.display = 'none', 300); }, 3000); } function updateCartCount() { fetch('/cart.js').then(r => r.json()).then(cart => { const n = cart.item_count; ['.cart-count','#CartCount','[data-cart-count]','.cart-link__bubble','.cart__item-count','#cart-count','.header__cart-count','.cart-count-bubble','[data-header-cart-count]','.site-header__cart-count','#cart-icon-bubble'].forEach(sel => { document.querySelectorAll(sel).forEach(el => { el.textContent = n; el.innerText = n; el.setAttribute('data-cart-count', n); if (n > 0) { el.style.display = ''; el.classList.remove('hide','hidden'); } }); }); document.documentElement.dispatchEvent(new CustomEvent('cart:updated', { detail: { cart } })); if (window.theme && window.theme.cart && window.theme.cart.getCart) window.theme.cart.getCart(); if (typeof window.cartCount !== 'undefined') window.cartCount = n; window.dispatchEvent(new Event('cartchange')); }).catch(() => {}); } function addToCart(variantId, onSuccess, onError) { fetch('/cart/add.js', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ items: [{ id: variantId, quantity: 1 }] }) }).then(r => r.json()).then(onSuccess).catch(onError); } const mainAtc = document.getElementById('main-add-to-cart'); const mainAtcLabel = mainAtc.querySelector('span'); mainAtc.addEventListener('click', function() { if (this.classList.contains('crc-added')) return; const form = document.querySelector('form[action*="/cart/add"]'); if (!form) return; const variantId = new FormData(form).get('id'); mainAtcLabel.innerHTML = 'Adding...'; this.style.opacity = '0.6'; addToCart(variantId, () => { this.classList.add('crc-added'); mainAtcLabel.innerHTML = '\u2713 Added to Cart'; this.style.opacity = '1'; showNotification('\u2713 MRX 1KD 3.2L Stroker added to cart!'); updateCartCount(); }, () => { mainAtcLabel.innerHTML = 'Add to Cart'; this.style.opacity = '1'; }); }); const mainBuy = document.getElementById('main-checkout'); const mainBuyLabel = mainBuy.querySelector('span'); mainBuy.addEventListener('click', function() { const form = document.querySelector('form[action*="/cart/add"]'); if (!form) return; const variantId = new FormData(form).get('id'); mainBuyLabel.innerHTML = 'Processing...'; this.style.opacity = '0.6'; this.disabled = true; addToCart(variantId, () => { window.location.href = '/checkout'; }, () => { mainBuyLabel.innerHTML = 'Buy Now'; this.style.opacity = '1'; this.disabled = false; alert('Error adding to cart.
