Tuning the Audi 1.8T engine. VAG 1.8T 20v Petrol engine as fitted to Volkswagen/SEAT/Audi {cars|automobiles|vehicles}: 150-240 bhp from the {factory|manufacturing facility|manufacturing unit}. {The fact|The actual fact|The very fact} these engines {can be|could be|may be|might be|will be} tuned to such extremes {indicates|signifies} the versatility of them. The 20 valves are {arranged|organized} with {3|three} intake valves {and 2|and a couple of|and a pair of} exhaust valves per cylinder. The compression ratio {is set|is about|is ready} to 9.5:1, {but|however}, a {slightly|barely} {lower|decrease} 9:1:1 {in the|within the} 240 bhp {versions|variations} of this engine, which {although|though} {high|excessive} for a turbo {gives|offers|provides} {plenty of|loads of} low down torque. {The standard|The usual} {cast|forged|solid} iron engine block is solidly constructed {and can|and may|and might} handle {power|energy} {levels|ranges} {up to|as much as} 240bhp in {factory|manufacturing facility|manufacturing unit} tune {and many|and lots of|and plenty of} {owners|homeowners|house owners} have reported {much|a lot} {higher|greater|increased|larger} {power|energy} {gains|beneficial properties|features|good points|positive aspects|positive factors} than that. A remap on {a standard|a normal|a regular|a typical|an ordinary} engine will {typically|sometimes|usually} yield {around|round} 40-50bhp {increase|enhance|improve}, and, with the addition of {a higher|a better|the next} {capacity|capability} turbo, a freer flowing intercooler and {efficient|environment friendly} induction and exhaust design, {power|energy} {gains|beneficial properties|features|good points|positive aspects|positive factors} to {around|round} 300-350bhp are {possible|attainable|doable|potential}. Expect to {have to|must|need to|should} {upgrade|improve} the clutch when {increasing|growing|rising} {the power|the ability|the facility} of the engine or the clutch life {will be|can be|might be|shall be|will likely be|will probably be} dramatically {reduced|decreased|diminished|lowered} the TT aftermarket clutches are {likely to|more likely to|prone to} be {the best|one of the best|the most effective|the perfect|the very best} {option|choice|possibility}.
The stronger engines had pistons from {forged|cast|solid} aluminum Mahle, with fracture {split|break up|cut up} {forged|cast|solid} steel connecting rods mated to a {forged|cast|solid} crankshaft which is {capable of|able to} {handling|dealing with} {far more|much more|way more} that the mild 150bhp tune and retaining reliability. When planning upgrades {it is|it's} {worth|price|value} {finding|discovering} out {if your|in case your} engine has the {forged|cast|solid} {components|elements|parts} already. The engine code is {found|discovered} at {the top|the highest} {part of|a part of} the engine {near|close to} the valve {cover|cowl} on the {side|aspect|facet} etched into {the head|the pinnacle|the top} {so you|so that you} {might have|may need|might need} {to clean|to scrub|to wash} it off {as the|because the} stamp {often|typically|usually} {gets|will get} {covered|coated|lined} in grime. An {obvious|apparent} {upgrade|improve} path for KO3 turbo {owners|homeowners|house owners} is to swap in a KO4 turbo. The {software|software program} takes {a lot of|a number of|a variety of|a whole lot of|loads of|lots of|numerous|plenty of|quite a lot of} getting {right|proper} for {the maximum|the utmost} {power|energy} {gains|beneficial properties|features|good points|positive aspects|positive factors} {but|however} {interestingly|apparently|curiously} {most people|most individuals} report that the KO4 turbo runs {fine|advantageous|effective|fantastic|high quality|high-quality|nice|positive|superb|tremendous|wonderful} on {the standard|the usual} manufacturers ECU Map. {It is|It's} {usually|normally|often} {easier|simpler} to remap {the standard|the usual} KO3 engine and set the {boost|enhance|increase} to 1 bar as per {a number of|a lot of|a variety of|numerous|plenty of|quite a few|quite a lot of|various} aftermarket Audi tuners {standard|commonplace|customary|normal} remaps.
You {may think|might imagine} the KO4 is {more|extra} {prone to|liable to|susceptible to|vulnerable to} lag {but|however} {this is not|this isn't} the case and {both|each} are very {similar|comparable|related} {as far as|so far as} low down low {boost|enhance|increase} {power|energy} goes. 1.8T weak spots and {problem|downside|drawback} areas. This {depends on|depends upon|is dependent upon|is determined by|relies on|will depend on} how the {car|automobile|automotive} is {driven|pushed} so {if you are|if you're|in case you are} are a heavy footed driver or make {lots of|a lot of|a number of|numerous|plenty of} {short|brief|quick} journeys on a {cold|chilly} engine the service interval is {reduced|decreased|diminished|lowered} from these figures). Use of the {wrong|fallacious|flawed|improper|incorrect|mistaken|unsuitable} {type|kind|sort} of oil will {cause|trigger} the oil pump {to seize|to grab} {causing|inflicting} a catastrophic {loss of|lack of} oil {pressure|strain|stress} and engine failure and {unless|except|until} {you can|you may|you possibly can|you'll be able to} {prove|show} that {the correct|the proper|the right} oil grade was used the {warranty|guarantee} is invalidated. Audi {long|lengthy} life oil lasts for {up to|as much as} 24,000 miles {but|however} all {other|different} synthetics are {only|solely} {recommended|advisable|beneficial|really helpful|really useful} for 9000 miles. It {seems|appears} {sensible|smart|wise} {to change|to alter|to vary} the oil & filter {frequently|ceaselessly|continuously|incessantly|often|regularly|steadily} as {metal|metallic|steel} particles {can cause|could cause|may cause} {damage|harm|injury} to the engine as they {become|change into|develop into|grow to be|turn into|turn out to be} suspended {in the|within the} oil. The engine takes 4.35 litres of {fully|absolutely|totally} {synthetic|artificial} 5w-30 oil (Audi {long|lengthy} life oil {must|should} conform to VW 504 00 or 507 00 (Castrol SLX {long|lengthy} life III is the {special|particular} Audi {approved|accepted|accredited|authorised|authorized|permitted} oil).
Some {users|customers} have reported {problems|issues} with early coil packs {but|however} most {of these|of those} {will have|can have|could have|may have} been {replaced|changed} now and newer coil packs {do not|don't} {seem to have|appear to have} any {problems|issues}. Fitting a blow off valve or dump valve {can cause|could cause|may cause} {problems|issues} with the engine {management|administration} as {there is a|there's a} {loss of|lack of} system {pressure|strain|stress}. There {are now|are actually|at the moment are} VAG {friendly|pleasant} dump valves that {also|additionally} recirculate the {lost|misplaced} {pressure|strain|stress} {keeping|conserving|holding|maintaining|preserving|protecting|retaining} the ECU {happy|blissful|comfortable|completely happy|completely satisfied|glad|joyful|pleased}. The air {flow|circulate|circulation|move|movement|stream} sensor can {become|change into|develop into|grow to be|turn into|turn out to be} soiled {particularly|notably|significantly} if {you use|you employ|you utilize} a filter which is impregnated with oil.
