I did a similar thread last week but about 330bhp. Now i want to know about 400bhp!

Just a simple list really will do. I dont want things like baffled sump for track use etc....

Cheers Guys

 

same as 330 but grp A fuel pump and re-wire,55lb black injectors or 400(light blue)or 403 (greys) injectors T34.63.

If 2wd will need a 4x4 inlet plenum

6 paddle clutch and heavy duty cover

 

Rewire fuel pump?

 

for a strong reliable 400 bhp id suggest a 200 long studded block std cr valve cut outs bd14 inlet gt3076 and 55 lb siemens 4x4 inlet..not only will it be strong and last longer than a rebuilt 205 block it will bring you bang up to date as in terms of turbo etc and youl have more than 400 bhp...oh yeah the turbo will last longer than a t34 at 2 bar to...
if your intrested pm me iv got a complete rebuilt longstudded engine for sale...
cheers danny

 

as i put in ya other post bud just renewing the old fuel pump wiring

 

Anymore?

 

So a stock 2wd pump can handle under 400 if rewired?

 

......my car made 420bhp on a "new" std pump and i ran it for 2 years before i changed it to a 044.........

 

Up!

 

Seems abit ott to me that Danny, i ran over 440bhp on a 205 block and the car ran over 400 for about 2 yrs before that, if going for 500 then i,d think about a 200block...GT30 aswell seems a waste of a turbo for just 400bhp..

I know where you,re coming from about do it once do it properly bla bla BUT there,s many 400bhp cars outhere that have been running alongtime with a 205block and a T34.63..

400 is always a strange number imo, i think a nice 370-380 makes a superb road car anyway..



Just my 2 penneth...

 

if going for more later on then go the route danny says
if doing it on a budget then
205 or 200 block, wrc head gasket, bd14in, verniers, 4x4 inlet, 3" exhaust, t34.63, greys, chip, good i/c, 044 pump.

although i would suggest a new loom with new fan loom and fuel pump rewire, new engine sensors, and a wasted spark kit would make it much nicer/smoother and seimens injectors over greys.
make sure the cooling systems up to it to, new stat and fan switch, make sure the rads clean and free flowing.

 

Cool

 

std engine, T34.63, o44 pump, 55lb siemens, 500 cooler,3 bar and our off the shelf chip will get you very close for little cost really.

 

Why??

 

check out cossierichs thread on his engine. makes an interesting read. no long studding or headwork, just an mad inlet cam, custom map, gt3071 turbo. fantastic drivability, torqy as feck and 450 ponies. quality!!

 

2wd inlets die at 385bhp.. my saph maxed out at this figure and i believe so did cossierich's... wasted Ł100 on a dyno to find that one out... running a tt38 at 2.2bar did 385bhp.. put a 4x4 inlet on and now she made 450bhp

 

get a big bank loan. Drive to peterborough. Meet a nice chap called harvey gibbs. A few weeks later you'll have 400 bhp. Sounds like a lovely recipe to me

 

i will second that +1

 

Dont need long studing.

Mine ran with cometic (if I remember rightly) metal gasket standard head bolts, greys, cams, T4, 500 cooler and some of NMS magic fairy dust...

Result 428bhp on the rollers and one hell of a kick up the arse on the road.

 

ive seen a few cars use GT28 and got good power.

everyone will say different but go with one tuner and follow what they say.
ask what they suggest and get parts yourself or them to get.

 

Really? Thought they were better than that...can't just just add a spacer rather than switching to 4x4?

 

Fun drive home that day too Jake.....

 

Bringing this back up again. Anymore input into this guys?

Will spacing the 2wd inlet give the same result as a using a standard 4x4 one?

I take it a T34.63 is the way to go on the turbo side of things, or should i go with a more up to date turbo like a GT30?

Injectors....... Siemens or Bosch? Does it matter? If so, why?

Uprated clutch is a must do as well as 044 pump and new chip.... anything else that HAS to be done?

Cheers Guys

 

I believe the elbow is a big restriction on the 2wd manifolds so spacing might help but wont be as good as a 4x4. I would look at the gt28 over the 30 if only wanting 400bhp as the 30 is possiby a bit big?

 

I would go for the GT3071 but speak to a mapper regarding exhaust housing sizes as you can get down to a .63 - go for a set of Siemens 83's if you can source some if not again seek advice from a decent mapper for an alternative, they may advice 55's.

If your engine is standard with no valve cut's then a Kent AB07 inlet cam is about the best on offer

A 4x4 inlet with a decent spacer is more than enough

 

If the thought of changing to a 4x4 plenium is worrying you due to price etc then forget it,as this is the simplist cheapest part of the conversion,as it is a text but set up

A standard T34.63 is at its limits running near 400bhp on pump fuel. Rainbird ran one decades ago at that power but it was on better fuel than we have these days.

sure it will do 400bhp but youll be running it at its limit of boost and it wont last forever.

The concensus on here the last few times this 400bhp question was asked was that the figure of 400bhp is a bit odd in tuning terms and its far easier to spec for 380bhp or jump to 430bhp plus.

 

Use a t34.48 it's less stressed at 400bhp than the .63

 

Hope your joking mate? I'm not worried about the price of things, I just want to know the difference of a 4x4 or spaced 2wd inlet. In fact I have a 4x4 one in the garage.

 

Ok so I'm realistically looking at 380bhp roughly if I do the above mentioned upgrades and use a t34.63. That's fine, as I'm not figure mad, but would like to feel more of a kick than the 300bhp my car makes now.

That's all I'm after really....

 

300 to 380 is a big jump

why not go 350 as that is what your car should be making anyway

 

380bhp with torque to match will feel much faster than the 300bhp you have now.

Almost all the cossie tuners will have a relatively simple off the shelf 380bhp package, although obviously you are better off having the map tweaked for your car as sometimes there can be a variation between seemingly similar cars.

Problem is, torque and power is addictive and after a few months with the increased performance, you will get used to it and want more

 

I know

I think I'll do the above upgrades and see how it feels.......
