Im looking to get 300-350hp from my import 205. Just finished replacing the suspension parts and want to start mods, so far there is a 3" xs power downpipe and full 3" exhaust and boost contoller pumping 15psi. Blitz ecu might get in the future but I would like to hear your sugestions. Thanks

300bhp is easy on the st205 so long as the engine is good to start with.

mine is way over 300 with the following..

3 inch aussie dp
3 inch aussie front pipes
blitz nur spec r
apexi intake
780mm x 320mm x 80mm forge fmic
blitz dsbc running 1.19bar

and a few other bits and bobs and with a few cooling mods to suit it works great.

i wouldnt touch xs power parts if you paid me though, they are cheap for a reason, they are cheap tat to be honest.

personally i wouldnt bother with a blitz ecu at all, im running standard ecu and the fueling is a rock steady 11.5:1 under wot where as on some of the blitz ecu's the fueling is all over the shop running lean and all over.

id rather take a few less ponies and keep the fueling rich on the four.

but if your engine is good, then a few mods will see it run 300 no problems, 350bhp will need alot more than just a boost increase though, and if you plan on running it hard then the pistons will melt under prolonged boost unless you can keep the intake charge low enough.

Rite on I will start with the intake and controller.

If you were in the US of Huh (or sadly the U of K since our horses started to get smaller ) then all you would need is an upgraded air freshener.

If you want 300 real hp then it is just about doable with a good freeflow exhaust and 1.2 bar of boost on a jdm ecu. If you want 350 then realistically you're looking at a hybrid turbo, good breathing and a piggyback ecu at least

Hi,

i would go the way 205 is talking about, but just only with performance pistons
and possible WAES

Ya 300 is good enough for this year next year I will have alot more spending money . What's a good intercoller for the 205 any links? Thanks

Hi,

the oem intercooler perfect for your application, just go for a 1:1,5 / anti freeze:water ration in summer, even i tested my fluid to -18°C without freezing (my fridge doesn't handle more)

Lol will change anit freeze but i would like to get a front mount sometime, would make it alot easier to work on car.

Hi,

why easier...where is the problem?

i compared the benefits of WTA and ATA intercoolers and it becomes clear that i will use a WTA system
i doesn't really know a english speaking homepage where you can get good infos but can do a short translation of my articel/benefits from gt-four.ch on request

a friend from denmark also compared HKS intercoolers agains TTE group A, i quote: lower intake themps and quicker spool up (~400rpm -> big turbo) with the WTA system

Ya well I sure your rite about the wta is better than ata. Queastion about the stock wta does the pump run contuniously?

The stock WTA intercooler is fine but it does have limits. Like all things you have to decide what compromise is best for your aims

For 300-350 on the road the stock setup is OK. At that kind of level on track you do see inlet temps slowly but surely creeping up. Especially since these are now old cars and most have severely impaired cooling due to corrosion on the water radiator.
Above those levels I'd seriously consider a front mount or an enhanced core in the existing WTA cooler as TTE did on the WRC cars.

In my book a FMIC does make life easier too
No bother to change the plugs, refit the CAT etc etc. OK it's not a big deal to unbolt the topmount and swing it out the way to do these things but every time you do so you run the risk of a foreign object down the TB or compressor outlet. I know I've dropped a screwdriver bit straight down the compressor in the 0.00000001 second gap between releasing the WTA and covering the inlet

The stock pump does not techniclly run continuously but in practise it really does. It's on a switch controlled from something by the ECU (either TPS or manifold pressure). Blip the throttle and it runs for 30 seconds. The only time it will not run is if you're sitting in traffic for longer than 30secs without touching the throttle

Hi,

no no, i don't say better -> i would not say better
you must do your own desicion

here we go

ATA:

- speed addicted
- pressure drop (pipework)
- higher efficiency (just one heat gradient -> air to air)


WTA:

- water can compansate speed addiction very well
- less pressure drop
- lower efficiency (two heat gradients -> air to water & water to air )

i'am sure i forgett some things,
here a link to the complete articel
http://www.gtfour.ch/info/faq.php?id=info&code=faq

-> choose Ladeluftkühlung
possible you have a friend that can translate for you

no the pump do no run contuniously, but run after you kick the throttle
no need to change this, but you can go for a jabsco pump

here some pictures
http://gt4dc.co.uk/forum/viewtopic.php? ... c&start=30

but should tell you that i will go for a bigger front radiator and TTE intercooler in future, this is why i mounted the pump

I made my own charge cooler a couple of years ago.



I`ll be making another one using the top and bottom of the standard chargecooler as the internals of the road car version are pretty poor, verging on minimal.

Looks very neat What core did you use on your DIY WTA chargecooler and what benefits did you observe compared to the OEM setup?
