400bhp project parts. What am I missing?
 
What with trying to sort this all via email and doing it inbetween working 16hour days on the other side of the world just wanted a fresh perspective on this to see if theres anything I might have missed out let me know if you can think of something from the small to the big I might have forgotten about. Aiming for 400bhp for starters the car is a V4 MY98 TypeR (Not worried about suspension, brakes or gearbox at present)

Sorted out so far:
  • 2.1 Stroker on CDB (Wiseco pistons, K1 rods, 2.5 crank, Cosworth engine bearings, Cosworth head gaskets and sump baffle plate, RCM oil pump and ARP head stud kit: built by Alan Jeffery)
  • RCM Headers & Up pipe (Heat wrapped)
  • Andy Forrest TD05-20G
  • Simtek ECU
  • Fuellab FPR
  • 3" Cat back system
  • 740 Injectors
  • HDI GT2 FMIC
  • Walbro 255 pump
Off the top of my head I think all I'm missing is a downpipe, clutch, induction system and........? Any sound advice would be appreciated.

Nah the box will last at 400 without me pasting it no problems that I'm very confident of besides i'm pretty sure the post says I'm not concerned about that for now.

it would be pretty hard not to with 400bhp under your right foot mate.:D
and what intercooler you running as well mate?

Sorry yeah HDI GT2 FMIC edited to include that.

prodriverules 08 August 2010 11:22 PM

i'd pretty much say get the things you've already mentioned you need plus an uprated fuel pump if you havent already and a good mapper and your there mate good luck with it,but plan to uprate the brakes and box at some point as it will take abit of stopping with that much go:thumb:

worbs 09 August 2010 12:37 AM

Paralell fuel rail set up maybe mate, an oil cooler, sytec fuel filter or similar, new timing belt poss a cosworth one + new tensioner if needed.
Oils, running in etc.
Probably not all necesitys mate but deff some things to think about, im planning my build at mo so in same sort of boat as you.

Yeah I can see what your saying definately things worth considering cheers.

Gearbox will be chewed up, you have the ty452 and its the weakest box in the line up, maybe running 320lbs of torque it "may" be ok, running 380lbs and it wont last long, so personally I would look at upgrading to either a PPG (expensive and it still uses a duff subaru 5th gear) or a new age STI box (stronger than the PPG).

Have you upgraded the brakes? no mention there, I would look at a good AP type setup, 330mm minimum or if you have the wheels for it, the Brembo's off an STI with upgraded pads and discs, look at the suspension, new springs and dampeners, classic suspension isnt that good on an uprated car, arb's etc also.

There is probably more to add, the biggest fact is that it costs a fortune to modify a classic and they are not any quicker than a big heavy new age, p2w doesnt count as the cd factor is different, and if you put the money your going to spend on that car into one thats 5-6 years newer, you would still have cash left over and one very quick (JDM) newage twinscroll model ;)

Aye Tony the box will come with time but funds can only stretch so far in one hit so I'll just need to take it canny for a wee while.
Brakes are on the plan already an will be purchased soon.
But as stated in the original post neither of these items are my main concern at present I just want to confirm I have all I need engine wise.

Cheers for blasting my hopes of a fast classic and the costs involved! haha
The main factor in the project was the cost of the car initially though I paid pennies for a non running TypeR and I think that for the price of a decent newage alone I've got a car and a good chunk of the parts required already. The Type R is also in my eyes is a damn sight nicer on the eye than the majority of Imprezas, a little less common and something I've had my eye on ever since I had a WRX around 5 years ago.
Thanks as always for the advice though I will bare it in mind when the box upgrade is on the agenda an I think the 6 speed will be on the cards.

A transplanted new-age STI motor and box, would easily take 400 bhp...

Just the wiring to sort out.

IMHO.

You're nuts! Newage will need more power to offset 250kg of lardiness :lol1:

catons scooby 09 August 2010 04:12 PM

just an idea mate,
my scoob is for sale 500bhp and its prob worth just playing with the idea of swapping all my running gear into your car,
if your intersted its in the for sale page, plus its got gearbox brakes etc etc and only been run in so virtually brand new
(just a thought)

mr_D 09 August 2010 04:26 PM

2.1 Stroker on CDB (Wiseco pistons, K1 rods, 2.5 crank, Cosworth engine bearings, Cosworth head gaskets and sump baffle plate, RCM oil pump and ARP head stud kit: built by Alan Jeffery)
RCM Headers & Up pipe (Heat wrapped)
Andy Forrest TD05-20G
Simtek ECU
Fuellab FPR
3" Cat back system
740 Injectors
HDI GT2 FMIC
Walbro 255 pump

+

braided fuel lines.
all gaskets ( inlet, exhaust. throttle)
vacum lines.
turbo intake pipe. (probably custom job.
inlet spacers, because you may as well do them while its off.
3 port boost solinoid
lightweight flywheel.
selection of new bolts. m6,m8, various lengths.
all fluids.
engine mounts?
timing belt.
pulleys?
tensioners
etc
etc

how about a newage powersteering pump with resivour relocation (contact me if interested)

KAS35RSTI 09 August 2010 04:39 PM

If you can then get a uprated clutch & i think your gearbox will be fine. I was running over 400ft lbs on a whining V4 sti box which took alot of abuse & its still going strong with the new owner.

harvey 09 August 2010 07:11 PM

If you are doing this on a budget and clearly you are then you don't need parallel fuel rails. There is nothing wrong with the OE fuel filter and aftermarket horizontal fuel filters can lead to problems.
Classics generally run less oil temperature than the 2.5s so fit an oil temperature guage or better still an oil temperature and pressure combined guage which will help you make a decision as to the need for an oil cooler.

mr_D 09 August 2010 10:02 PM

But there is the problem of lack of fuel to last piston on the line and it's advised to do it for precaution ???

Most of what you've mentioned will be dealt with whilst Alan builds the engine.

Think your missing the point I already have all the stuff listed an it's in the process of being assembled.

Cheers Harvey aye I'm trying not to kick the ass out of the cash spent here in one hit but it can stretch and little extras will be added as an when required might email you for advice when things progress think the fmic might have arrived now.

Aladdin I've heard this from a few people who are running them like that and have done for some time so I'm pretty confident it'll last as long as I need it to seems alot of people talk about things they have no previous experience in and heard off a mate. I'll maybe be proved wrong we'll see when it goes together, going to invest in a modified Exedy which should be more than capable for the figures i'll hit just now.

dunx 10 August 2010 10:05 AM

But some of us have been through it, and seen it these last 13 years of Scooby ownership... ;)

My std. clutch cried enough at 360 ft.lb.s, and several WRX owners I know have eaten a gearbox at only 300 bhp.

Good luck !

dunx

P.S. Parallel mod can be as simple as two 8mm brass t-pieces... and an fpr adaptor.

OK in answer to your question, not at 400 bhp. Either that or I have been very lucky several dozen times or this is another Scooby myth. You can decide which. Nice to have but far from essential and not required at 400 odd bhp. Would certainly want it in Duncan's position on a Time Attack or big power track car. On one of my own engines we were running well over 500 bhp and had a set of headers with a lambda sensor boss in each branch. There were differences cylinder to cylinder but not to do with the fuel rails/system.
Dunx has pointed out how cheaply it can be done but there are dozens of cars out there with parallel fuel rails and fuel systems in general that have cost hundreds of hard earned pounds that are totally unnecessary at that level of tune. If the build is on a budget as most are, then leading someone to believe they need things that are not necessary may mean they do not proceed on cost grounds.

I'm not questioning that maybe some people on here have owned a Subaru for 13 years and have had the problems more the fact that some people on here leave elaborate replies on many posts not just mine which makes me question if they have experience in it happening to them or just heard/read it happened to someone else an don't know the full story or don't want to share it.

The clutch is getting replaced as previously mentioned above.
Is the WRX box not different from the V4 TypeR?

Cheers for your advice anyway.
I'll be interested to see just how long my box lasts after the reviews I have i'm 50/50 on it but for the amount of time I spend away I'm sure it'll do the job for long enough before I uprate.

stef28-2008 10 August 2010 06:29 PM

ive got alan jeffry building me a 2.2 lol ive got the tdo5 20g m8 700cc cosworth oil pump and all that and ive got a black box blitz thing on there dont know wat it is im getting andrew carr to map it him and scooby teknix say will weŁ 400+ 2wk befor i get it of alan do your brakes m8 i got brembos put on cost me 400 fitted and ive just got a
wr1 6 speed gear box Ł 2000

ok thats what i was looking to hear, but i have mates who are subaru mechanics and even they say that this is an issue due to the amount of engines that go on the last piston because of running lean. im only saying because of the stories i have read on here and from the information from subaru mechanics.

not saying its a big thing that is 100% needed. but lets be honest when doing a big you want to do things right first time and any type of precausion you can take to stop anything bad happening then you would want to take it. even if you yourself have been lucky. we all know people who have been unlucky.

harvey 10 August 2010 07:29 PM

Sorry I have only been lucky a few dozen times like I said above. I do agree when you are doing a big build it is worth investing in parallel fuel rails but 400 bhp is not a big build by the stretch of anyone's imagination.
On another topic I think it is a falacy or another Scooby myth that number 3 piston usually goes. It is not my experience and others with far more engine building experience on Subarus because they build engines day in/day out have confirmed this too.

stef28-2008 10 August 2010 08:53 PM

a lad at work has the 2.1 nothing gone wrong on his apart off gear box he left the type ra in lol

786omar 10 August 2010 08:59 PM

My old Type R made this on a 2.1 stroker with an 18g + 10%meth, with stock fuel rails parallel fed, your setup should easily make the same if not a touch more, as above i doubt the parallel feed to rails would have affected the power / tourque output

stef28-2008 10 August 2010 09:05 PM

thats good it should be evil then im not bothered about bhp its torque i want lol i love it when it pins you back in seat plus my wife gets sick lol

Grant74 10 August 2010 10:11 PM

If you are gong to throw it around on the track then a proper baffled sump rather than a cosworth windage tray
