really happy with my car

was built to have decent power/reliability and without an endless budget but with some goodies, sc46 turbo, simtek ect

the dyno i used was the first time ive been and seemed a really good set up

the printouts are a bit squashed when i post them - i dont know why?

but i think they are still of use?

What spec is your engine? Headers? Exhaust? Injectors? FMIC/TMIC?
Induction?

good reliable figures there mate !

Also have a 2.5 fitted to my classic with simtec ecu, need new clutch and flywheel in the new year then a trip to corten miller for a dyno run ,would be interesting to see what its actually running before i get it set up for the track next year.

Nice one !

its a shame photobucket seems to have totally fcked the images of the afr ,inj duty ect.

making them almost meaningless - ill wait until i dyno it again and see if i can get an email of results sent, or just buy a scanner lol

alcazar

the spec i s new2.5, sti 3 heads, forged pistons, uprated oilpump, alloy rad, race bearings - standard rods and studs - so have to stick to moderate boost levels, cometic head gaskets, cosworth baffle plate, sc46 billet, simtek, roger clark gt2 headers, blitz full system, hybrid fmic, rcm intake alloy trumpet and filter,

think thats it lol

cheers mate - i just went all out and bought a decent clutch kit and lightened flywheel, sure its an act set up (i think) the way harvey explained to me, get a good clutch first time and you wont be changing it twice a year if your doing some track work and the odd 1/4 mile blast

wise words imo, think my clutch is rated to 505lb/ft

let us know how yours get on, when it hits the rollers mate

Jet can I ask why go to all that trouble and money and not do the rods and studs?

iTrader: (2)

What size injectors, and who mapped it?

jef

iTrader: (13)

basically the project evolved bit at a time tbh, money was available, at certain times, tbh i didnt think i get this far

i decided the that just over 400bhp would be perfect for my road going classic


there is a bit of added expense with machining block, heads, a stud kit, probably twisted turbo set up
,probably, ect and i thought, rightly or wrongly, it would be a touch more relaible running slightly less boost, whilst still bring able to give it a good bla
st whenever i wanted

lol and breathe, - if you get me mate

Injectors 740s and was mapped by bob rawle, at one of harveys weekends

been a while in the making, but really happy witht the result from harveys build and advice

what identification will tell me what heads i have fitted (external) or is this immposible to make without stripping down ?

If you wanted 400 bhp, then why didn't you go for a turbo like a md321h or similar. Your turbo seems to have a great deal of lag. My own setup uses a 321T. The torque curve goes very steep by 3000rpm and peaks well before 4000 rpm.

Wheel output surely?
An SC46 + 740 inj @ 85% DC must be more than 340 hp fly.

I have never seen any graphs from this dyno before. The results are wheel horse power and I don't think you can rely on the AFR graph or any indication of spool.
The STi 3 heads are ported and had new valve guides etc. Personally I think the STi 3 are best to go for. The car also has RCM GT2 Spec headers which I wrapped and one of my special uppipes. On the road as Jeff will confirm response is instantaneous with 1 bar in 4th below 3000 rpm.

Lee: To identify STi 3 OR 4 heads you can look at the inlet manifold stud pattern which will be in line as opposed to version 5 or 6 where stud holes are offset. That narrows it down to versions 1 to 4. Version 3 and 4 heads are shimmed and the STi 3 and 4 has the bucket over the shim whereas WRX 3 and 4 is bucket under shim.
I hope that helps you.
I have a set of STi 3 heads with minor porting and surfaces flattened ready to fit £500 if you want them.

I have to agree with andy97 if you were aiming for 400 why stick a sc46 which as far as I know is suited for a 2.5 and is a 450'turbo, surely to run that turbo you would need to ramp the boost up but knowing it can't due to the rods and studs I would of thought a smaller turbo would of been best but hey at the end of the day if parts came up cheap and it does the job then who as we to comment lol

Please dont take the above the wrong way its clear that you have got good results and are well chufged and to be fair As long as you are happy and enjoy every minute then that's all that counts,

My understanding with the 2.5 is to go for the next step up of turbo for which you are aiming. The MD321H would have struggled to get near to 400hp on the 2.5, wether the 321T would spool faster over the 46 is more probably down to the car spec than down to an individual turbo.

i dont take offence to anyones opinions - and enjoy a good debate, The engine is a 2.5 unit just incase i hadnt made that clear

and97 i wanted over 400bhp but obv less than the 450 which from my reading was nearing the limits of the standard rods, so was aiming smack inbetween, which seems to be exactly what i have. im not great with graphs ect, why do you think its laggy?

the power delivery to me feels almost instantanious - the car at no point at all feels laggy. now i havent driven a 500bhp plus subaru with different turbo, the lateral ones for example, but im over the moon with the delivery from this one - no joke, i couldnt fault the delivery at any point, im sure it hits 1 bar under 3000rpm according to the dyno operator.

according to a few dyno operators ive spoken to the power roughly equates to 437lb/ft and 422bhp, so thought the sc46 fits that bill perfectly?

its a beast on the road, and i really beleive the whole spec of the engine, box clutch+flywheel,headers and ecu works excellently together -

like i said tho im comparing it to nothing, as ive no experience with more powerful cars with different turbos.

but i do also beleive those that do have vast experience and have driven it and set it up when they tell me it delivers very well.

im chuffed as fck haha!

we'll see how long it last until i want more lol

like i said i like other peoples feedback, and have no problem , esp when its backed up with some interesting info

the graphs unfortunatley are really skewed - i rotated them in photobucket and its made them go very strange, all squashed, the torque/bhp one is the only one thats similar to the origional

brilliant jef as said as long as you are happy and again it looks like it has produced a very good all round package, out of curiosity what gear box are you using, i have heard many times before that around the 400 mark makes for a fantastic road car so hope you enjoy it.

i cant wait to get back in an impreza don't get me wrong love the forester st/b funny car to drive, performs fine has impressed me with this weather but really looking for the next project

jef

iTrader: (13)

cheers stevie

im using a 6 speed i bought of tingtong (sp) on here and its a great bit of kit

im not sure but i think its a jap box with the shorter gearing - maybe helps with the feeling of no lag

even in 6th, foot half down, and your pushed back in your newage sti sets lol

you going for a mega build stevie?

it's a uk box jef

thanks tho

UK box has the same 1st-4th ratios as a JDM box just 5th and 6th are longer

Can you explain in laymens terms please ?

iTrader: (48)

Buy and STi 5/6 inlet manifold gasket from Roger Clarks and get an STi 3/4 inlet manifold gasket at the same time. Get them to mark up which is which.
So now by matching the gasket to the inlet side of the cylinder head you can decide whether the cylinder heads are 3 or 4 (or possible 1 or 2) or version 5 or 6.

Now look at where the cam turns to actuate the valves. If the cam lobe turns on to a flat bucket then you have an STi head, version 3,4,5 or 6. The shims that space out the valve clearance are under the bucket If the cam lobe turns on to shims which are sat inside the inverted bucket then you have a WRX head.
If any of this is too much to understand as it may well be unless somebody physically demonstrates the difference to you take your heads to a local specialist in your location.
