Hi guys, what's the best bolt on turbo for a 2004 STi looking for 400hp or close to.
It must be truly bolt on with no mods required.
I have seen the sc40 which looks great but what else is out there?

Cheers Ian

 

The Turbo Technics T36 is aimed squarely at that target. In fact we've easily been exceeding it. We would say it's a good choice between 380 and 450 bhp being capable of running 2 bar boost. It's a billet wheel turbo, direct bolt on and comes with an oil/water line fitting kit. Price only £1080 including vat delivered.

As below!



It's available exclusively from us on 01752 345880

 

Mmmmmm
Must resist.....
What's the spool like on a 2.0 Alan ?

I have also been looking at this turbo.
I'm ideally wanting to increase my top end.
Do you have any idea how it performs on a 2.5 Sti?

 

A bit like that

 

I'm interested too. What about a group buy?

 

would be interesting to see back to backs, shame i never had mine turned up from the low boost setting as a comparison for the 46+.


an boost/afr graphs from that martyn

 

 

Now that's a good idea. Lol

 

what are they tending to max out at martyn?

judging by that graph looks like its a cracker

 

Always hear good things about the MD turbos, I myself got a Zenperformance TD05-20G, should get around 370/80bhp once all mapped up - other supporting mods too though..

Edit: your not just suddenly going to go from 300bhp to 400bhp by just changing the turbo...
You'll need an upgraded fuel pump, fuel pressure regulator, 3 port boost solenoid might need bigger injectors too though could be wrong.

 

SC42 plus seems good!

 

My mapper has recommended the sc42 but I really like the price of the T36.
As for upgrades I'm already running a Bosch 044 and will be upgrading the injectors as well. Oh and I have the 3 port too.

 

Ahhhh ok, you didn't say that originally. Sounded like you were just expecting to get 400bhp lol

 

Seen 470bhp and 460lbft from one fitted to a Hawkeye with a built 2.35 but we're recommending it for people looking for 380-450bhp.

 

An MD321H billet would be good opinion also. But has a expensive price tag.

 

yeah theres a few turbos around the same sort of target power with different price,in reality i think its only what couple of hundred in it?

but untill someone back to backs the same car dont think you'll find out exactly which is best, results seem pretty similar so cheaper option may well be best route to go.

 

I want a t36

 

Well it's a toss up between the T36 from Alan Jefferey and the SC40/SC42 from the clinic, the MD321 range looks great but has a massive difference in price. So the T36 is winning at the minute.

Thanks mate but the Owen developments turbos aren't truly bolt on plus there are no prices on the site.

 

What other mods were needed to achieve this on a 2.5??

 

Built engine, GT spec headers, 3 inch exhaust, 750cc injectors, Perrin front mount and induction, uprated fuel pump.
Nothing particularly trick, just basic supporting mods. Mapped on Ecutek racerom.

 

can tell its ecutek cos of the fueling hahaha

check out the similar fueling fluctuations on mine and that one as they come on boost

 

It's back for a Syvecs now Tidgy

 

I've got one of the t36 turbos from engine tuner on my 2.5
Mapped by martyn...
384/440 lb ft and that's still with the standard top mount and a cat.......
Thumbs up from me....

 

Any twinscroll options that retain close to OEM spool, I know there are custom Owens available?

 

Hahaha, not surprise tbh. Was in the list to do on mine as well before I sold it. Although I do have Syvecs on the R now :-)

 

Seen any results for the t36 on meth yet Martyn?

Desperately penny pinching for my ecu and splash of meth

 

Not ran one on anything other than pump fuel yet m8, I'm betting it'll be awesome 😆
