hi all i have a mk5 rs2000 engine fited into my mk4 cabby and was wondering what i can do to increase bhp. its had the egr removed. got exaust, airfilter ive looked at chip but £249 for extra 12bhp seems a bit steep. ive heard about putting 2.3 bottom end on? can out else be done before this

all help appriciated

 

Mate sign upto www.rs2000-16v.com

quite a few guys with 2.3s over there.
some mental turbo builds aswell, one is featured in PF this month.

 

The 2.3 conversion is a bit of a ball ache for the power increase U get
Suppose to be a fair amount more torque though there's a guy doing superchips on eBay for 120 I think!! I'll find the item number and post it for ya tbh mate I drive a 2000 everyday an it's a giant killer round the twisties!! They rev well too it's jus there very high tuned out the factory so without turbo or supercharging/throttle bodies you won't see big ponies from the i4

 

i tried signing upto that mate but never got confirmation to activate account for some reason this was months ago

 

check the junk/spam folder as thats where they usualy end up

 

ok thank you i think ive seen it gives extra 13bhp is it worth it though lol

 

quite easy to get 170 out of a I4 but if you want to nudge nearer the 200 area, then be prepaired to start spending money big time

 

Yh that's it mines around 170 mate and that's good safe reliable power
If ya want 200 or more go to zetec/zvh power for tuneability and cost the i4 engine in the super 2000 series what the rs2000 won where only around 275bhp so they've never been in the league of big power as such

 

As said, 170ish isn't too hard to achieve. Loads can be done to this engine. The thing is, you'll never get massive gains from tuning a normally aspirated engine without spending loads of money. It's not like a turbocharged lump where you can just wind the boost and fuel up a bit, you have to put a bit more thought in to it, and the gains aren't always as simple. That doesn't just count for the I4 either, it counts for all aspirated engines.

If your manifold has been modified well, that's a good start. An ECU chip is generally considered worthwhile, then you can move on to other things. Headwork, modifying the inlet to remove restrictions, cam changes and things can all move things along further. Then you can fit throttle bodies for even more, or go down the 2.3 (or even 2.2) route.

It's a myth that these engines can't be tuned. Parts aren't necessarily so widely available, but they're just as tunable as a Zetec; you just start with more power and torque to begin with.

I think Mountune proved they had the minerals. Race versions of the Escort Maxi peaked at just over 290bhp even back in the late 90s, which is pretty good going for an old 2.0 engine designed in the late 80s.

As said above, the RS2000 forum is a good place to start, as lots of people have tried lots of different things, so you're bound to get some inspiration there

 

Thanks for the help. Think ill aim for 170
