Hi guys, I am posting this for a mate as he has no internet access. The aim is for a reliable daily driven 500bhp on optimax. I am hoping you guys could take a look at the spec list and tell me if you think we have mist any think or if you think it will get to the magic 500bhp mark.



This list is from memory but here goes:



Up rated 225LPH Walbro fuel pump

FSE power boost valve

Modified fuel rail

740cc injectors

4 brand new coil packs

HKS fuel cut defense

HKS 40I spark plugs

HKS SPF induction kit

HKS tubular manifold

HKS group N down pipe

Custom DP Motorsport 3" down pipe back with single rear can ( no cat )

GT30R turbo

HKS FMI

Turbosmart external waste gate

Apexi power FC and remote commander

Apexi AVCR boost controller runing 2 - 2.2 bar

WRX bottom end

Bored and honed closed deck block

HKS 2.2L stoker kit

API STI version IV head's and cam gear

API 14mm stood kit

API Triple layer metal head gasket

API up rated engine mounts

API up rated 6 speed box with prop, viscose rear dif and shaft's

Exedy lightend fly and dule plate carbon clutch

325mm Brembo discs with gold 4 pot Brembo calipers

Performance friction Carbonmatalic front pads

New STD rear discs with EBC Redstuff ceramic pads

Goodrich braded brake lines



That’s all I can remember but im shore I have forgot a few bits. What do you guy’s recon?

500 bhp and reliable are two words that don't go together in a subaru engine!

Personally, that list seems like a real mish mash of parts, and not really very well thought out.

A single Walbro pump, and FSE reg' are marginal to say the least, and you would be far better off with an SX or similar reg', and a Bosch '044 fuel pump.

The Garrett GT30R with external WG needs custom up, and down pipes, but most of the 3" systems will work fine.

Has your friend already bought these parts, or are they what he thinks he needs to get ?

I would suggest looking into this a little further before making any decisions, as I doubt any of the guys with "quick" cars would suggest this combination, myself included.

Doesnt seem very well thought out, looks as though your friend has looked at a motorpsort website and just written down all the parts that they sell.
I mean with the power fc you wouldnt need the HKS fuel cut defense

And some spelling lessons wouldnt go a miss either.

. . . . wouldn't go amiss either.

A guy with the financial ability to build a 500bhp car doesn't have access to the internet?

I know this won't be easy and the is always a trade off but we are just going to have to see how it turns out.

R19KET
The singel Walbro pump is on the car already and we are looking at may be a twin or a higher LPH pupm like the bosch one you mentioned. We know the GT30R will need custome pipe work and this is sorted. 70% of the parts have been bought already with a few bits to go. In respect to you saying you would not suggest this set up then i would appreciate any thought you may have over what to run.

Jaytc2003
Would it surprise you to know that 90% of this set up has been recomended by Dave @ DP Motorsport, Grant @ AET Turbo's and Dave @ API. the has been some thought gone into this list but if you want to surgest some think then i would appreciate it. The HKS fule cut is already on the car and if the Power FC replaces the need to have it then keep an eye out for it on E-bay, thanks for pointing it out mate.

Zippy
Eye wiped hey mate

Cheers buddy, im not the best speller in the world but what it has to do with tuneing a Subaru is beyond me.

RoRu
I know mate, it's mad to think that some one with the money to own and mod a Subaru dose not have the internet or even a PC but there you go. Why would you want to tune a car in a School yard?

What is ment by your coment i don't know but if you want to enlighten me mate then fill your boot's

To much strong cheese before bedtime make people dream, light hearted bantor, but you do seem to miss matching alot og good componments

Doubt you could have 500bhp on plain optimax using a gt30r?

jaytc2003

DP Motorsport are good, I used them many years back with a different car that I had, they are expensive though, maybe why they suggested 90% of those mods. Im currently about to get a power fc and commander fitted and mapped from someone with a very good reputation for £800 all in, DP wanted £1800.

The HKS stuff is quality, but there is cheaper and often better quality//performance alternatives availlable which will save your mate money, look around, read reviews, there are plenty on here.

I am also thinking why have 500bhp for a daily runner? you cannot really utilise its full potential on the road. Why not go for a 2.5 conversion, have it tuned for say 350bhp (more chance of reliability than a 500bhp wrx bottom end which will have been weakened by it being bored - less material = less strength), this will result in better fuel economy and a much more pleasant drive.

Ah get you know LOL

Did you got to POD last Sunday, if so did you see Louis Robinson's Pulsar GTIR?
It wasent in the pro pit but it did do a 11.1sec 1/4 runing 500bhp on a GT30R on optimax. It may be harder to do with a Scooby but we will try.

Jaytc2003
Dp motorsport are doing the build but only about 50% of the parts are comeing from them. The before mentioned HKS manifold has been droped in favour of a Megan Raceing one and we are looking at outher things to save £££'s on. I know what you mean about the daily driven thing but the lad who's car it is lives in St Ives in Cornwall and all the roads are A B or M so it will be used every day. DP Motorsport have been good enugh to G/T the engine for reliability so if it dose go wrong then im shure they will sort it but for them to G/T it then they must have the confidence in it in the first place.

how much are they charging you for everything that they are doing?

Bill looks to be about 12k plus API's 6 speed box.
That £1800 for a Power FC, fit and map must be wrong. I will ask them about that and see if they have made a mistake.

AndyF from Forrest performance (Search on here will find him), he currently has a scooby that can do quarters in either the low 9's or 8's (cant remember which)
I would advise you speak with many tuners first before putting all your eggs into 1 basket so to speak

Are you based nr warrington? If so if you do get all the stuff done, wouldnt mind a spin in a 500 bhp scooby!!

jaytc2003

Got an email at work telling me thats what it would cost. I enquired through their website and got an email back from Dave himself saying that it would be £1800 to suppley the power fc and commander, fit it and map it

getting robbed u are man, hope ur friend has a lot of money, personally id rather sell up an have a far more reliable 500bhp r33 gtr?

Spoke to Andy Forest on Wednesday after watching him on the Sunday be for and got some good advise. I have been out in quite a few car's that DP have done and always been impresed so i think they were a good choice for the job. The car is not mine unfortunatley as said at the top of the post, it is a mate of mine who lives in Cornwall. I live in Liverpool my self and he dose have to come up in about 4 weeks to get the car so we will see what we can sort about you going for a RIP.

I take it you know what some of these bit's cost and if so i don't think it is a bad price.

flat4_ire

£1800 for the apexi pfc fitted and mapped is a rip off man, think most guys here know that not just me

al125

iTrader: (2)

I carn't coment on that mate as it dont seem right to me but yes it dose seem to much when they do an Apexi SAFC, Apexi AVCR, fit and map for £1200 and unlike the Power FC were it just plugs in this all has to be wired.

R19KET

al125,

Andy F will give you good advice, and so will others on this board, but it seems like you've already decided what you're doing, and just want us to agree with the choices that have already been made.

I wouldn't waste your money on the Megan headers. They don't last long on a mildly tuned car, let alone a car running high boost.

There are alternatives that are tried, and tested at 500bhp +, and are still reasonably priced.

The GT30R is a good turbo, and capable of 500bhp, although it may need a little help in regard to some fuel additives.

Without knowing exactly what you actually have, it's a little hard to suggest things to you.

Mark.

flat4_ire

yeh well im not sure on the other stuff but i know that the average for A'pexi PFC supplied fitted and mapped is between £750-£850

flat4_ire

what i dont understand if he has the money to wax on gettin the scoob to 500hp then why is he putting optimax in? why not run it on race fuel?

I put the list up to see what peep thought, the are still bits to get. If you have some think in mind outher than the Megan Manifold then let me know plz as this has not been bought yet. In respect to the GT30R Grant at AET said it will have the larger houseing so it will flow almost 600bhp.

Flat4 ire
It is a daily driven road car that he wants to have a bit of fun in at some events. Race fuel may be used at an event next year but never on the road.

flat4_ire

sure im a 4th yr apprentice electrician dont be trying to get out if it that easy!! fecking builders! i use ngk7s in the sti type r, they the best to get u reckon?
