Nivå: Lätt men kräver kunskap om motorer.

300-400 horsepowers on for this engine is still small numbers and the stock internals can handle it very well. 300-400hp is one step above “software–only” tuning and you will have to replace some parts. Just as any modifications on this engine, the software is the most important part, if you don’t get that right you will not have horsepower or torque and worse case, you might break your engine.

• 4 bar kartsensor(essential)

Motor

The stock intercooler has plastic parts and it will pop at 2 bars of boost (about 29psi), so you will need to replace that with one that is fully aluminium. You should aim to get one as big as possible but for horsepowers up to 400 something like 140x550x60mm is big enough. The stock internals will handle this kind of power well.

To feed more air to the engine you will need an updated turbo, hybrid turbo is good, this way you can get up to 400hp, we also have plenty of turbos available, you can contact us on email if you desire to buy one from us.

The OM648 high pressure pump will word up to 350hp and upgraded pump up to 450hp.

Spridare

Stock injectors will be enough up to 300hp, from us you can purchase street injectors (up to 85hp per cylinder), these are made for the stock piston but can also be modified if you decide to upgrade later. The product includes injectors only, seals and return lines etc. need to be bought separately.

• För att utnyttja dessa injektorer fullt ut måste bilen remappas, detta kan ske på två sätt, vi skickar remappningsfilen till dig via e-post eller så skickar du din ecu till oss för remappning.
• Se till att monteringsytan på injektorn är ren, använd stålborste med borr om det behövs.
• Make sure that the injector seal is correct spec. We have best experience with stock seals (1,56mm)
• Dra inte åt injektorerna för hårt, standardspecifikationen är 7 Nm +90 grader +90 grader
• Använd alltid nya skruvar och nya tätningar/brickor

Turbo

Your best bet here is to update to an updated hybrid turbo, we sell these too. Check it out below. However if you want to achieve the 400hp you need something even better. For that we have developed EVO serie turbos. Next step after that is the Holset HX35MFS and our stainless steel exhaust manifold:

Motorstyrning

När du köper injektorer från oss mäts varje set individuellt. Dessa mått bör beaktas när du gör mjukvara, du kan välja att köpa mjukvaran till din bil för ett reducerat pris när du beställer dina injektorer. För 300-400hk behöver du också skaffa en 4 bar kartsensor. Denna sensor är plug-and-play så inget krångel där.

Drivlina

Stock 722.6 (W5A580 with om648 and om613) gearbox can easily handle the 400hp power. However if you want to make sure it will last forever (oil change every 60000km) we also recommend you to get our transmission tune. Also it activates true manual mode so the transmission won’t upshift automatically, you get faster shifts, less torque converter slipping and torque limits removed:
