i want around 350bhp and these are the mods so far

Mods

The mods on this car are as follows:

SS Peco Exhaust System
3G 20 Groove Discs on Front and Rear
Greenstuff pads all round
Koni SSK Suspension – Adjustable front and rear shocks + Springs
Gtech 1
Unichip
Apexi AVCR EBC
Forge DV006 Dump Valve
K and N 57i Induction Kit
Walbro 255 Up-rated Fuel Pump
Pro Alloy FMIC (from group buy).

The last rolling road was 264.3 bhp and 247lb/ft (safe with Unichip)

so whats next apart from a turbo and how quick is a 350bhp coupe

doesn't that seem a little low?

yes but so is my bank balance feel free to lend me money lol

350 should be an easy target but expect to spend about 3-4k getting ther safely!

see above..

but are'nt you going to lend me the money panic

anyway whats next mod wise a turbo then?

yep gt28r or rs or rsr!


take your pick

the r is on a group buy from atp turbos for around the £600 mark the rs is obtainable for about £750 and pass on the rsr i neve found out.

i know of a second hand gt28r with downpipe for £450 if your interested!

how much of a bhp gain would a turbo give me goose

40bhp but you mite have to do something with your exhaust system and then get another remap too

Neither GT28R or RSR will give you 350bhp without headwork. If you're just after a headline figure buy yourself a 0.86 GT28RS or GT2871R. The 0.64 GT28RS should get you 350 with the right ancillary mods but it won't come cheap.

That sounds like a challenge to me Kenno.

i thot that too and look where it got me lol

I've got a hat here with some salt and pepper incase you break 350bhp Matty.

Remember - it must be a standard engine.

You might like to think about some better pads to go with those 20 grooves if you get nearer to your goal . Green stuff (EBC, I assume) aren't a whole lot better than standard ones IMHO. Get yourself some Red stuff or, better still, some Pagid Blues .

Sorry, brakes before power lecture over for this evening !

Phil

I'm 100% standard. But if she breaks it's your fault for setting that challenge.

LOL.. your mission SHOULD you choose to accept it.

Right 2 bar of boost here I come.

What if i get over 350bhp kenno?

Ross

Aye, like you've got a standard head Ross. Your head is mad.



So is the one on your car.

Yeah but what about the 28r?? over 350bhp without mapped?

Ross

I'm not saying it's impossible.

It's just without porting the manifold, getting a flowed head, using an uprated fuel pressure regulator/fuel pump/injectors, water injection, 350bhp is a big ask for a standard engine with the R and RSR. Considering how much that little list above costs, an extra £200 for a GT28RS over the GT28R is a cheaper way to get to 350bhp.

and Ross.. you may get 350bhp unmapped but somewhere in your rev range the fuelling won't be optimal.

Matty - 2Bar eh? It'll make 400bhp but just the once..

Lol. And im pretty sure if you had a wideband lambda, you'd find the same

Ross

I have an AEM Wideband AFR Gauge in my Nomad pillar...

And having spent £500 for a mapping session I bet mine's much better than yours.

Well what was the problem with getting the power from your car then? Thought proper mapping was the biz?

Ross

A faulty DV and lack of fuel at the top end didn't give me the top end figures i wanted. I'm going to use a 3.8bar reg next time. IIRC Suba with his GT28R and headwork couldn't get more than 320bhp until he installed a 3.8Bar reg.

Where are your graphs?

Graphs?

This is with gtech2, running slightly rich midrange (nothing to worry about really).

Ross

Well I will push 350bhp. Question is, how much more?

U know my feelings on this dude. Doubt u will break it with proper mixture of fuel.

More torque = yes. More bhp? Doubt it. Redline figures are all good.

Ross

change your pads now greenstuff pads are only rated to 200bhp
