Home made Turbo kits.

Some chinese made turbos are ok they such as the kkr and xspower, more seen in the jap cars but def dont go the ebay specials.

I wouldn't touch any of them - especially when you can pick up a nice Garrett for 600 from the US. Even the MHI EVO 9 and IHI VF22s are silly cheap from GruppeS in the US -about half what MRT want for them

Not the best option for a 6 cylinder, though, is all...

Ehem, Vortec blower, ehem.

it doesnt take much effort on google to bring up all sorts of complaints about xspower turbos. I remember a couple years ago there was a famous photo of one of those turbos housings just falling apart

Come to think of it, I might look into the SC14 S/C for my 2L.. hmmmm ideas ideas.......

A piggyback ECU would do what you need for a Mk3. Could get away with a piggyback and SC14 with some bits thrown in for less than $2K I think.....

I'm not aware of any piggybacks for Mk3s, certainly none that address the lack of a MAP sensor

turbo

After reading everything there are some points that people fail to realise .

Anyone can make a cheap turbo system that will work on , say a Golf VR6 , but , you need to take into consideration a few things . Its a N/A engine that your converting to forced induction so your going to need an oil supply line to the turbo , You can use the oil filter housing and tap into the oil temp switch or oil pressure switch . The oil return is a bit trickier , you need to get the right angle and size out of the turbo and into the sump . If this is wrong the bearings on the turbo dont get the right lubrication through flow/pressure and eventually they collapse . I went through 3 different return pipes before I got the angle / length right on the s3 . The coolant supply is a little easier since you only really use it to maintain operating temp of the turbo and once switched off allow coolant to flow through the turbo so it doesnt cool too quickly ! I highly recommend getting a turbo timer hooked up to an electric run on pump as is found on VR6 , t4 2.5l and most turbo VAG cars (except golf gti) . Or in the case of the VR6 , just plumb it into the turbo or even run a second one .
Positioning of the turbo is another issue . Looking in the engine bay there is heaps of room behind the engine , but the amount of heat the turbo generates means it really needs a lot of shielding so you dont melt brake booster hose or any other plastic bits on the back of the engine bay . Also pending where the turbo will sit , you may run into problems with the turbo down pipe being very close to the brake master cylinder !
Pipework is fairly straightforward as long as you have a good fabricator / welder that can do all that work . Positioning of the DV will also help with spool , as will knowing what pipe size with the turbo size and intercooler size so do your research there !
Tuning will probably be the biggest hurdle . Every Mk3 VR6 Ive tuned has either been full stand alone or just a Giac chip . I am unsure if the ECU is tunable using American based chips . We do not have OBD on our cars so our ecus are different to the ones in the US . But it may work because all you need is the base tune and manipulate that . Anyone tried lemmiwinking a mk3 ecu here in Aus ?

Anyway , after all that I would rather just get a supercharger kit , seems so much easier , probably cheaper too and more reliable . The only issues Ive heard about with charger kits is the belt coming off . For about $5k locally sourced they are a better alternative , well , unless your seeking 400hp+

In 1998 when I was doing work to my 1995 VR6, I had the option of a Unichip piggyback or a remap of the ECU by VW Motorsport.

The tuning house that did the piggyback also had a wicked 3.1l and 6speed conversion.

In the end I opted for the VW Motorsport remap as the other was just too expensive.

Today I would have opted for VF-Engineerings supercharge kit for the VR6 though......

Like this One?



There's some other good pics and a bit of XS power background on this blog. http://www.jdm-insider.com/Blogs/Eri...&submit=Search

That is a VR6, though - the 2.0 ECUs are a different story

No one's ever heard of Haltec before?

Systems start at 750, your looking at 1,500-2,000 with a completely tuned system with free back-ups when the idle or tune comes out, and the founding owner is in Whetheril Park Sydney!

Its still beyond me why people even bother in paying for soldered chips when you can get a completely tunable standalone ECU's for either the same price or a few hundred more... All that jap boys do it, and they're always thinking about budgets too ya know...

[Bug_racer]

I will choose a chip over stand alone any day for daily driving . Ive had both and can tell you that a factory ecu is a lot smoother to drive . Jap cars are basically a really fast tin can (thats what they feel like anyway) and most dont care about cars driveability .

Well, thats in the circumstances where it isn't tuned properly, find the right tuner and you will never have a problem. And if you do end up having a problem, you can just come back for free to upload the tune. Do you have that level of support from a chip manufacturer?

Do you sell both standalone systems and chips, or just chips out of interest?

I ran a Haltech on my turbo 1800 16v. It took a while to setup properly, but was awesome when done. No complaints

If you are going fully custom a full aftermarket ECU is the only way to go.....

[Peter Jones]

I want to assemble my own MegaSquirt ecu for my 2.0. They're a bargain if you happen to have good electronic and micro processor skills.

I'm still researching the options here.
