But they dont tell wath engine can be the donor (4g93,4g67, or 4g63) or maybe a Hyundai engine.
Group 2 Modifications
Okay the basics are done and you have a plan. The following mods require you to decide, which of the following ways you are going which will be
1. Staying with the 1.5 SOHC Cylinder head assembly for some further mild tweeks mostly in braking and suspension.
2. Upgrading to the 1.5 DOHC Cylinder head conversion, with more medium to extreme tweaks
3. Looking to turbocharge with either the SOHC or DOHC cylinder head assy
First decision - SOHC or DOHC cylinder head. We can only say one thing here - go the DOHC every time. If you don't want to do this then skip the next option and move on.
1. DOHC Conversion Package
The DOHC head conversion is quite simply the best option if you seriously want any more power from the vehicle. A Naturally aspirated tweaked DOHC package will outperform any SOHC variation short of turbocharging. Its superior flow characteristics cannot be beaten. By itself with the stock 1.5 SOHC computer this is worth 8kw at the flywheel with an increased working RPM range. This is a one day conversion which can be performed for under $2000.00 AUD$ by simply swapping the cylinder head and other minor components.
We usually source a complete 2nd hand motor, replace the timing belt and waterpump and then fit to the vehicle with RPW 4-1 Extractors, this engine comes standard with a 51mm throttle body.
You need to decide at this point because any extractor / turbocharger route requires a specific manifold / extractor for the specific cylinder head model which cannot be swapped across to the alternative.
This package upgrades the vehicle from 65kw on average to around 76kw on average at the flywheel. With above mods the vehicle should be close to around 80 - 83kw at the flywheel. Approx value around $2000.00 fitted.
