Hi to everyone, is there anyone here still rocking on a wira in 2020? Would like to know any modifications guide / maintenance I should do to get some performance in my old wira hehe. Since the car is quite old and I think I should do some maintenance of the car to keep it running good. Is there any DIY cleaning or maintenance I should do?
Things I already done:
- Cleaning spark plugs
- Engine Bay cleaning
- Fuel Filter change
- Engine Oil & Oil Filter Change (Motul 4100 turbolight)
- Radiator flushing
Which WiraSE model is yours? 1st batch manual? 2nd batch manual? Each batch had different equipment. All had the rubbish JRD 16" rims though.
Only the first batch SE had a muffler, front springs, extractor, interior, body kit, rear ARB, rear disc brakes and 16" rim. Most later models didn't get anything except the rims and muffler.
The Wira SE front spring is very unique but considering how old it'll be, it's probably sagging now. You may want to look at aftermarket coilovers. After market antiroll bars (front and back) would help with handling too. There's a few bars from UR that are great - the fender bar, front and rear strut bars, side bars.
The Wira SE rear muffler is actually a very good muffler. The only problem is the material it's made of is rubbish so it probably would've corroded by now. The Wira SE extractor is also very unique, if you don't have this then a good 4-2-1 extractor, change to 2" piping and a straight flow rear muffler would help. If you want add in a straight flow pillow type resonator to reduce drone.
Brakes pads (front and back), change to a lightweight 15" rim, use good tyres like Federal RSRR 205/50/15 would change the way you drive.
Finally - the 4G15 is a very simple engine and the VDO ECU is a pretty smart ECU. Got money consider a complete transplant like a 4G93 mivec or turbo. Not much money, get a 4G18 Waja crankshaft, the campro piston combination to oversize and stroke your engine to be about 1.7L. Get a proper standalone to control everything and one of the cheaper ones that you can opt for is MaxxECU or ECUMasters.
