Obviously a decent turbo like a gt35r,But what else is needed, what injectors? what head bolts, what work to head, what pistons, what rods, what cams, what management, what clutch, etc!

 

Copy rods car! Cant go wrong and you know it will be fast!

 

Decent turbo and a gt35 don't go in the same sentence far far better turbos about for 600bhp

Proper h section rods with cps

10 long studs, not your shity arps

A lot of head work both sides

Cams
Inlet 2wd ex manifold

I'd put it on pectel and run a twin plate paddle clutch but a ap 6paddle should do

 

just read up a few threads, a gt30 at 2.5 bar with a decent spec YB would be best option for my budget

Jim what power could a gt3076r make on a Yb,forged bottom end, wrc gasket, ab07-bd14 inlet cam, ported head, siemens 83lph blacks, 6 long studs,, and On standard L6?

 

The GT35 is a awsome turbo and the GTX35 is even better.

Mark

 

Hahaha I awaited you Mark

 

I would go with the GTX3071 or a BW EFR.

Mark

 

Budget and 600bhp are not the first two words that spring to mind when thinking about this lol.

 

No where near 550-600 lol

Don't piss about with mild cams get a set of cams from someone who's been there and done it

Depends on who ported the head too but 530 at 2.1 bar I imagine,

We've seen 545 at 2.2 bar with out new inlet

I wouldn't say running 2.5 bar is the best way to go, slightly bigger turbo and 2.2 bar there's turbos out there that you won't loose much down the bottom

Gt30 even in the big ex housing suffer with high back pressure at higher rpm too we dine a lot of testing with them

 

500-550bhp territory.

I won't go above 400bhp on L6! Strongly recommend changing...

 

learn somethin new everyday eh!

best road going spec would be gt30 no doubt, as with over 450bhp in a road car will probably be too much anyway, Just been reading chips posts.

 

my spec mate...

200block long studs
forged pistons with big valve cut outs (standard compression)
lightened and balanced
full race spec head
custom profile cams to suit spec ( mark^^ could do them)
gt35 with external waste gate and screamer pipe
reyland modded 2wd manifold
83lbs siemens
r&b motorsport inlet (hart is the best tho )
big cooler ect ( spec r bar and grill type is the best)
big spec r breather set up
autronic sm4

and about 14k lol

and should be well over 500bhp but if i had the money and fitted a hart plenum and spec r cooler it would be close to 600bhp


MARK mine is nearly done now and ive put a inlet on and a bigger breather so will book in this month for a remap

 

The hart inlet will give you no more power over the r and b sweedish
Neither will the cooler!?

 

why do they make so much more on guys like rod and ads then?

 

Thats like comparing apples to oranges, the engines are completely different?

For out and out power theres no difference,

We have proved the sweedish inlet to be just good at 700 no more, they're not the best inlet but they make the peak figures
The hart, when modified will make that power, and more

So at 525 bhp both are having a easy time so to speak

 

i see what your saying but if said cooler cools better and more efficiently and said inlet flows better and more efficiently isent it going to keep its bhp for longer when hot and make peek boost faster then be better on all power levels

 

I'm talking about peak figures
Yes the cooler will keep all it's power there for longer, but peak fig won't change

 

hi what are the reasons not to use a l6 over 400bhp?

 

Thats just made me spill my tea . How can 450bhp be too much.

 

For someone not used to a 2wd car rod a punchy 450hp can soon catch you out!

And where I live a 450hp low lag engine will beat anything

That's why I'm having one in mine lol!

 

my 395 bhp & 410 lb ft is plenty quick for me cant imagine what 550+ is like

 

whats up with the sweedish inlets out of intrest ?

 

exactly rod, Quickest car ive drove is a 4x4 proton evo rust bucket or a stage 3 saph!

Like jim and paul have said low lag punchy 400-450bhp is where its at!

 

Couldn't have put it better myself Adam - i know how much money i have in mine and i am know where near that sort of figure, i wouldn't know for sure but i would guestimate the bill for a complete 600 spec build to be around Ł25-30k maybe more depending how fancy the parts are

 

You also have to bear in mind the transmission, that wil cost five grand minimum.

 

Fit a standard beam back on your car and you'll soon remember


Depends what people are using it for ultimately though, if all you want to do is put your foot down on dual carriageways and motorways in high gears then you'll always want more power, if its making genuinely quick progress down twisty roads though even 450bhp is still 100bhp more than a WRC car dont forget!

 

So WHY have you put a thread up asking for 600bhp then??

 

Anyone used a 4G63 engine inside

 

If it helps you my basic spec is
200 block,
Cosworth Pistons,
Neil Roper head,
AB07 and bd16 cams,
GTX30 turbo,
External wastegate,
Airtec cooler,
Hart inlet,
L8 management,
And it done 540 on both an engine dyno and rolling road

Cheers Paul

 

Instead of a YB in a cossie? No point, cant see it being any cheaper or more reliable (believe it of not a properly built and maintained YB is a reliable motor!).

 

Deep pockets lol

 

I have done plenty with that engine

Mark

 

Is it an cheaper engine to tune to big power (500bhp+) than the YB?

 

It ends up being about the same.

Mark

 

Interesting.

Have you had any dealings with the 3SGTE that is in the Celica GT4's and MR2 turbos. Good engine?

 

Think Fensport are the people to talk too with celica GT4/MR2 engines.

 

No as main dealings with engines are Evo Yb Porsche.

Mark

 

What compression and how thick is the gasket ?
I was thinking of buying 2mm head gasket .

 

I belive the 4G63 is more reliable and it can Rev crazy. Just a though as I am pretty familiar with them .

 

If you are talking about the Evo engine I only use a 1mm hks head gasket on all my engines over 600hp.

Mark
