Want 400ish bhp what's required
Ok so my main question is engine wise what can I use, i currently have a 99 type r and am on a limited budget, I'm looking to get a Second hand build to drop in if Im lucky enough to find one 
Would someone be kind enough to give me my options engine wise, Basicly I want to understand the differences between a forged 2ltr a 2.1 & 2.5
Aim is 400ish which I no is just beyond a standard sti engine..
Thanks in advance

if your on a budget i would say
sti 8 engine (£1200+)
vf48 turbo (£350+) probably wont reach 400 but will be close 380bhp+
fmic £250
then you need injectors/pump and some decent plugs
you could run the 5 speed box at your own risk,my mate runs his 5 speed at 400bhp in his classic and the box i use came from a 380bhp classic,dont launch it and you should be fine
remember its not all about numbers,a vf48 might not make the 400bhp but it will certainly give you a very fast car,350bhp+ in a classic will be bonkers

Currently running 380 in my type r mate
Engine wise I went for the 2.5 forged build but the money starts running away lol I would stick to your plan of finding either an sti8 engine or a forged build and drop that in.
Im running at td05 20g which I have to say is a great turbo on the 2.5 making bags of torque.
As for the gearbox mine is fine and tbh I love the short ratios and the dccd so I will be keeping it and worst case scenario get it rebuilt if it lets go.
Good luck with it mate hope you get it the way you want

TT I'm already running a apexi .. Can u give me a brief rundown on avcs heads I'm a classic man so this Newage stuff although I heard about it I don't really pay much attention to it lol
Ok so sti 8 lump , the heads will need changing for v5 correct ? To suit my needs why would avcs come into play ?
What sort of price am I looking at to have the heads changed over ?

How often do sti 8 engines come up and is it just a case of buying a long engine striping the heads and fitting v5 heads ? What about inlet manifold do that need to be changed or do I run the sti 8 manifold
Already running a walbro 255 and I have a hdi ready to be fitted so thinking turbo and injectors .... Also I guess if I go sti 8 lump that will make me top feed injectors correct ?

My only bit of advice would be when buying second hand engine is try to get as much history as possible on it,as good maintenance is the only piece of security you will have,as if it blows its down to you unless you can get a bit of warranty from the seller which is like getting blood from a stone.if it was me I would always go down the rebuild route as you know exactly what you are getting,and you can build a engine that is strong and fit for purpose,it mŷ seem expensive in the beginning depending on which rebuild you go for but as far as I'm concern it's money we'll spent for the added security.SJ.

Thanks sj yes will be looking for as much history as pos... If I had the money I would be having a fresh rebuild but funds are tight so it's looking like this s my only route ....

Your heads on a Jap short motor.
Since as you say you're on a limited budget, you don't want the added expense of an ECU to run the AVCS heads that a newage has, your Apexi can't run them IIRC.

Crazy I ran 380 for a year and 400 last 6 months on a v3 engine and v3 Dccd type r box been fine. Any one that knows me knows I don't drive lightly and good few launches.
Your box ty54 quite a bit stronger than mine again tho you be fine with 2 litre not so much torque. My engine been fine but Iv brought a Sti v9 engine jdm so 2 litre.
Jdm has nitrided crank and hyper cast pistons (weak point) the pistons good for 450 ish
Uk have forged pistons and banny ran one to 522 but I would say 450 to 500 be safe

How rare are the sti 8 jdm motors, I mean am I gonna be looking for years ?
450 bhp would be more than enough I'm aiming for 400 ish anything above is a bonus ...
I'm gonna sell my current v5 engine as a long engine so I will need to find another set of v5 heads so are u able to tell me what I'm on the lookout for
Jdm block
V5 heads
Head gaskests
Turbo ... Twin scroll ??

Yea any uk or jdm short block , head gaskets , sti 3,4 or 5 heads will be fine , a sc40 billet or 20g a decent one actually I would go sc42 that will give u 420 plus just get mapper limit torque if still on 5 speed. Try your engine at 380 be fine mate saves on the Sti 8 engine etc worrying to go 6 speed . A 380 type r is rapid trust me mine at 402 on type r box is pretty quick. Where you based if you in London way il take you for a spin? I'm running a sc40 billet

To the OP - your current engine has forged pistons but from what I've read the con rods would be your weak point.

I don't wanna go twin scroll but from what I've been reading I thought sti 8 was ?
I woud love a sc42 but with another G on top its getting pricey !
Thinking jdm or uk short block ( if it makes no diffrence ) another set of v5 heads.. gaskets ...Single scroll turbo 20g etc ( would love a sc42
)
Ok so what sort of price am I looking at to the the heads bolted to the block, I'm gonna give a few places a ring tomoro just wondering what to expect.

Harvey smith ran good power through these boxes and said if given respect there be ok. I don't take it easy at all been fine for year and a half if it was gonna go it would of. Andy forest had one dragging at 440 for a long time.
To many myths on here. 400 in a standard classic v3 Sti engine still going strong here and si jgm says she sounds sweet still after a year and a bit at that.
Never really asked Harvey the full explanation but he said the Dccd 5 speed boxes were stronger

Speak to lateral or import car parts there brilliant. Actually I seem to just use Alyn at as performance now tho. My recommendation keep your engine and box run 380 400 you be fine try find a decent 20g pretty cheap , lateral reflowed injectors and jgm remap done
