Hi ya folks, my 52 plate vRS is currently running 230bhp and 228lbft of torque thanks to ECU remaping, which is very nice, however i need MORE POWER! but I've not got a lot to spend. Can anyone sudgest a long turm power increase in power ie not a fuel addative or race fuel. thanks. :orb_futur

Any other mods apart from the remap.

From what I can gather from reading on here, the best bet for initial tuning is:

FMIC

Exhaust +cat back and downpipe/sports cat

Decent induction setup

Remap

You then have the option of upgrading to a K04 turbo, or going to a larger one.

Basically, it depends on how much you want to spend. I'd be inclined to look at an FMIC first, as you dont want to keep trying to get more power through other means and increasing the intake temps.

Hmmmm, once a remap has been done I'm not sure there is a non-costly way of upping the power above 230bhp?

First thought would be FMIC but you're looking at a monkey for that. (£500 for the non Cockney sorts) Exhaust would be £400 odd for a full system.

Wouldn't go the K04 route......costs a lot to get it to work properly. IIRC is produces around 240bhp.

Leon Cupra Rs manage 250-260bhp on the K04, but they also run twin intercoolers which helps.

As you say though, it's not the most effective route... Garret GT28rs conversion could be had for about a grand... and that's good for 300bhp+ (with other mods).

If I could have got a GT28 conversion for £1k I would have had it......I think the turbo alone costs a grand...then you need a new or converted exhaust manifold....injectors...uprated fuel pump....TIP.....downpipe....a remap and service (as new oil line has to go in for turbo)....oh and FMIC.

Your looking at at least £4-5k inc fitting.

You cna have an E05 turbo conversion for approx £1.8k....which will give around 270-280bhp but you must be careful not to run silly amounts of boost....turbo will go pop.

The Cupra R uses a different K04 to the bolt on one available for the 150/180 engine.

Ok, not the whole lot for a grand, but you can get the turbo and the manifold for under that.

If you're willing to fit it yourself and do a bit of scrounging then I cant see why you cant do the whole lot fairly cheap.

Lets see...

You'll have to pay for another remap to take advantage of the mods already mentioned if you want to use them to their full potential.

Which remap have you had already ?

Are we looking here for more power just for a greater quotable bhp down the pub, or more power you can actually feel makes a signifcant difference on the road or track? If you are after the latter you're not going to get it without spending a lot more cash.

If you're paying for someone to do it for you, once you've got the basic remap, I'd say you're looking at £1000 - £3000 more for every 50bhp thereafter, and as you climb higher (i.e. in the 300+ range) the more you pay for less return. Agreed?

Forge TIP and turbo back exhaust then tweeks to your current map.

wont give you massive increases over your current power but will give torque increases and a smoother delivery

you should see some gains but like everyone else has said without spending at least another grand or two on bolt on's and bigger turbos your not going to see any massive gains from here on.

Why doesn't the US manifold fit?

I'm beggining to see how the costs mount up... Christ, by the sounds of it it's cheaper to reliably turbo a honda engine than increase the power on a VAG turbo engine. Seems that things are well overpriced for these engines...

Why doesn't the US manifold fit....

It puts the turbo into a position where it and the downpipe conflict with parts that are mounted differently on our RHD cars compared to the US LHD ones.

I know someone who is trying to DIY a GT28RS and finding a manifold is the biggest hurdle. He is currently looking to source it from Australia.

I doubt turbo'ing a honda will be particularly cheap when you take into account the internal work to lower the compression and sorting engine management etc..

It's worth remembering though that if you go for a big turbo from a decent tuner and buy it as a complete installed package the work will be warrantied. This is a big consideration for most people as this will be done to their daily driver, that's certainly the case for me.

i think the US stuff doesn't fit because of the LHD/RHD issue causing clearance problems.

its not that these engine anre expensive to tune its just that you are used to a cheap one that has been tuned for many many years.

my brother has a focus and to turbo or supercharge that costs about the same as it does to uprate the turbo on the 1.8T.

My 150bhp VAG turbo engine went to 220bhp with a

out of interest what power would you reliably get from that honda engine as a daily driver?

nitrous ? or what about this ?

I have recently read an article concerning a Mark IV Golf where the solution to the above was move the entire engine forward 10mm to get the required clearence. On the face of it, sounds fairly drastic, but is the engine is coming out anyhow for internal work etc., I guess a bit of engine mount modding isn't too much in the scheme of things.

All depends on the type of engine really.

D16 (the common 1.6 like in mine) can be taken to around 185bhp or so (from 120ish) on standard internals.. I know 2 guys who have rover coupes with boosted D16s @ around 180bhp.

Then there's the B series DOHC VTEC (the one in civic vtis). B16s (1.6, 160bhp standard) can easily make 250bhp with a turbo on standard internals.. some have made more. Even in nasp form they can get over 200bhp if well tuned.

The B18 (180bhp std) can make closer to 300bhp reliably.. although not the one found in the integra typeR.. that's the C5 and tends to be weaker due to the higher compression and lightweight internals.. ideal for nasp tuning though. The B18C1 and B18C4 are the best bets for affordable honda turbos.

The K20 is the engine found in the modern CTR and ITR, that can take about 300bhp also I think, although I dont know much about that.

B series can make silly bhp if you uprate the internals and spend a bit more dosh mind...

The B and D series can be turbo'd for peanuts these days though. Complete setup probably wouldn't even cost £1500..

Unfortunately I'm more of this train of thinking.. so all this spending crazy money on already turbo'd cars comes as a bit of a shock, lol.

well the 1.8T can make 350+ on standard internals and 500+ with better internals

I've had a look at turbo kits that give 250bhp on the honda engines which include turbo, IC, injectors, pipework and software but no exhaust, start at around $2800 which when you add shipping, duty, vat etc.. comes to alot more than £1500.
