What's the limit of the SC38?
Is 400/400 realistic on our engines?

 

What would be gd pads instead of blue stuff on this type of setup. Won't be doing track days

 

Performance discs and pads highly rated

 

Pads are abit down on the back. Probably give Godspeed a call

 

Just ordered by cobra exhaust turbo back with sports cat

 

My not by,

 

What!!!
Brembos will easily handle some hard abuse, with the right combination of disc, pad and fluid.

 

Just pads refresh needed

 

The problem with shooting for 400 bhp is not getting it, it's maintaining reliability once you have it...

To give an example, here is the parts list for my 53 plate bugeye making approx 420 bhp and 400+ lbft...

EJ20 engine stroked to 2110cc
Spec C short block
Nitrided (forged) version 9 crank
ACL main bearings and bottom end
Oversized bore to 93.5mm to avoid piston slap and increase displacement
Mahle forged pistons and Manley forged rods
ARP head studs
Roger Clark high pressure oil pump and oil cooler
Tegiwa Imports oversized aluminium radiator
Mishimoto radiator hoses
Wiseco 1.3mm head gasket
Cyclinder head overhaul tenors and skim titanium valve stems and retainers
STI cams
18g vf34 hybid ball bearing turbo
Walbro 255l fuel pump
Deatsch Werks 750cc injectors
Autobahn 88 inverted FMIC with custom short route pipework to meet reversed inlet manifold for quicker spooling.
FMIC pipes also heat wrapped
Silicon hoses everywhere.
K&N induction kit, in-wing mounted
OBP oil catch can with K&N breather
Tiao blow off valve
Roger Clark GT spec equal length exhaust manifold
Full Mongoose 3 inch straight through exhaust.
Exhaust Manifold, up pipes and down pipe heat wrapped
Eibach lowering springs -10 mm on standard STI dampers
Standard Brembo 4pots with 326mm drilled and groove disks
EBC Yellow Stuff pads all round
Expensive uprated clutch
Decent tyres on standard STI wheels
Probably a load of other things as well.

Just shelled out for a set of Defi gauges to keep an eye on things...

All in all it has reliable power and drives nicer than the standard car, but it's cost a small fortune in parts - luckily for me, the previous owner did most of this...

 

Gd point.

 

Fit some Performance Friction 2part discs and pads, not worth skimping on brakes if you can afford to spend the extra, even for road use, the difference between these and some grooved and drilled standard discs is night and day.

 

Sell your brembo's and get some AP 4pots.

 

Il have sell my wife and kids for parts for car

 

 

I've heard that the US market for injectors is slightly better(?) than hours. If you were to bring some injectors back from the US to help make 400bhp on a Blob STI - what would you buy?

I don't even know if mine are side or top feed injectors

 

My 3" cobra exhaust came 2day. Mint
Another thing to tick off my list

 

As much as it a nice spec its not needed for 400 bhp a new age engine will be fine to around 450 on standard internals

 

It seems future proof for more

 

That's exactly the reasoning behind it... If I need to go into the 500 bhp territory, I know I can.
I'd rather have something over-spec'd with a good safety margin than run something that might be marginal. At the end of the day, the engine is only as good as it's weakest link...

 

I suppose if u get bored and want more u know it should handle it

 

More bits on the way. Might start a small project thread

 

but the newage engine will take 450 bhp all day long, its 3k thats not needed if the guy only wants 400bhp, also in regard to skimping id say he has done just that with a budget turbo, its not all about numbers its the way it drives therefore a laggy old turbo is no good a decent billet one is whats needed.

 

+1 As above there is no need to buy unnecessary parts as the 2.0 litre STI lump is already primed to take some serious power over standard,with carefully selected mods and the right size/spec turbo and fueling you will be surprised what power can be achieved.SJ.

 

Semi closed deck block / small studs would be the weakest link for 500 Bhp

 

There's a few that's already around that bhp power with their original block.SJ.

 

Yep, de-cat down pipe, fuel pump, fpr, 3 port, billet SC38 jobs a good un, he'd be as near to 400 as makes no difference for a fraction of the cost. You can go the "whole Hog" but why spend that money on on stuff that's not necessary for a fast road car, better spent on brakes and handling. As above it'll out spool, out stop and show a clean pair of heels to a much more powerful car with crap brakes and suspension.

Quality brakes are worth at least 50bhp when you know how to use them, same goes for good handling. The example of a bloke I met in the petrol station with a 600+ bhp yank tank holds true here, he said my WRX PPP would still kill him in the twisties with a mere 265 ish bhp, regardless of all the banter on here I know it's no match for bigger bhp cars on the straights and would be on the ragged edge just to stay in sight in the twisties, but I'd out brake the standard brembo set up every time.

 

Jura ran 500bhp with scdb, and shaun is running 490bhp on a standard jdm as well as banny doing 520 odd on a jdm bottom end.

CDB's were a bit of a "fashion" a few years ago when everyone was experimenting that has carried on in Subaru folk law and not really necessary for 500bhp, better off spending that £700 between the various engine components and sundries at that level.

 

Sure but how long will they last - they will eventually get bore walk and HG failure at that level IMHO
450 lasted 10 years/ 18k miles for me with an obd before it went as above

 

For how long...

Jura did very little mileage before the car was broken, same for Banny.

 

Got a cobra sports cat so it won't be a full decat. Looking at a sc 42 billet
