if i wanted to see 300bhp and similar torque from my uk classic, what sort of turbos could i use?

im considering getting a low mileage one second hand if the seller is trust worthy and then having it fitted/remapped to achive hopefully above figure.

vf28, vf34?

the car as many know is a my99 uk classic. have a good panel air filter on there and a full 3" decat (nur spec-r), so i would have hoped 300 was a good target? i would be happy with that for this car.

suggestions on capable turbos please? second hand/recon prices also? the car wont/doesnt see track days and its mainly just for little squirts now and again.

cheers, andy

 

for that level TD04 hybrid mate.

You'll want an uprated fuel pump, 3 port boost solenoid and I'd reccomend the samco turbo hose kit, and ported and wrapped headers too.

Would make for a supremely responsive drive and should get you to 300 and similar torque

As usual, I'd suggest you have a chat with David at APi

 

after discussing with david before i got the impression that the turbo and remap alone could/would achive this.

 

Zen put a VF35 on mine (~£250 second hand IIRC) Uprated fuel pump, Roger Clark 3" Sports Cat system , STi8 intercooler + Paul's magic all combine to give about 325-330. Any more and I'd be worried about my gearbox Original (?) 70K clutch is still OK (except occasionally on cold/damp days in 5th at around peak torque - only happened once or twice so not really a major issue as yet)

UK MY99

 

so looking at responces thus far, uprated fuel pump seems important too.

so safely im looking at
new turbo
remap
fuel pump
as minimum to get to my target

gearbox is new, clutch is new so 300 shouldnt be an issue.

 

He may have been under the impression that you already have an uprated fuel pump. I would say you should definately consider that!! Generally folks upgrade the fuel pump when remapped on the std TD04. 3 port boost solenoid also a good idea, can be had for 20ish quid second hand and will enable better boost control.

You don't need the hose kit and the ported and wrapped headers, but the std hoses can split under increased boost pressure and the ported headers are just a good mod: lower boost threshold, improve responsiveness and get a few more ponies out of the car across the rev range.

How much do you want to spend?

Ns04

 

Yes, should have said it was about 300 with just turbo,fuel pump,remap & de-cat downpipe (otherwise standard exhaust), the Graham Goode (not RCMS!) and intercooler were just the icing on the cake

 

well ive got ancillary hoses inc radiator etc already.

oh and the samco kit which includes the y-pipe and intercooler hose. is this what you mean ns04?

i presume if i could get hold of the boost solenoid and turbo/fuel pump, david would fit them the day of the map?

i dont wanna go ott, as the car has 136,000miles on the clock (current engine is 66k) so i dont wanna spend £1000s when eventually its worth nothing.

so a safe 300bhp for a couple years is what im after.

sooo...

remap £?
turbo £300
fuel pump £?
solenoid £20-30

 

well bear in mind what ever you have done will be usable on the new engine, if the worst happens, but im running a vf34 and supporting mods at 340bhp on a my00 uk turbo with 85k on it and its fine.

although i should add i'm on a ppg gearbox, but that went before i got to 340

 

Remap for a new ecutek3 license for example will be minimum £500-550 choco.

 

just seen andy f's post on the '£200 mapping' thread. unless im mistaken, £587 all in inc vat. that is a bloody good price and i could be tempted without a turbo etc to see what i can make on the td04 and nothing else.

opinions on that?

 

260's mate

 

so standard im on 215. got a full decat air filter and decent engine hosing, sounds like fun. although for the sake of adding a turbo for say £300, i may get more fun

 

lol, well you'd need to add a fel pump, and you may have heat issues

 

heat issues? please explain?

 

oil temps might become an issue.

i had a decat remap, then a set of defi's fitted, on hot days oil temps recketed when playing. kept having to back off

 

i have a vf28, that should see u to 340 with supporting mods, spools up quick as well so good for ur short "squirts" but for more power u wana get the vf34 that can go 400bhp

i looking to get the vf34 as myself, just need to sort other things out 1st

btw u would need that fuel pump just to b safe, they not that expensive either

i currently running same car as u:

440 injectors
walbro 255 fuel pump,
vf28,
decat ninja uppipe n centre,
magnez backbox,
remapped,

got a printout for 284bhp with 280torque - a more aggressive remap would prob stretch to 300bhp

 

vf34 aint gonna hit 400, 350max, mines at 340 and just about out of puff

 

il double check, a vf28 can get u to 340 (prob its limit) so i was sure a 34 could go higher with supporting mods

 

no mate, the vf35 and 34 are very similar, 35 does 340ish and the 34 does 350, 35 is a vf 30 with a smaller exhaust housing to improve spool rates, but reduces overall punch, 34 has the larger housing but is roller bearing for quicker spool and same pnuch.

or at least thats my understanding

 

Take Tidgy's word for it mate; you're not going to get 400bhp out of a 34, not unless by supporting mods you mean a) Nitrous or b) a very optimistic RR

340is also VERY rare on a VF28, 300-320 range more common.

As the OP wants 300 a hybrid TD04 would be the best bet as it spools the quickest at that power level.

Ns04

 

i stand corrected then 2 ppl saying iv got me figures wrong haha

with the 340 on vf28; that iv seen first hand, so its definanity poss, tho prob is pushing the turbo abit hard

 

I've heard of one VF28 produce 340 too. I don't recall which RR peoduced the figure nor what the supporting mods were, but I do seem to recall comments to the effect of "blimey that's unusual" (though not so polite ) and "the turbo would be under a lot of strain to get that figure". Again, expressed in a less polite manner!

 

which dyno was it on? lol

there are some very optimistic ones out there lol.

although you do sometimes get odd ones that break the mould and the trend, i have seen a standard td04 break 300, only just, but it did witht he right supporting mods.

also got 258bhp and 280ftlb on my old td04, which is strange for the torwue to be so high

 

How about a good old TD05 16G

Tough critter, early spool and can be mapped to gearbox smashing potential.....a bit "old school" but it would be my preferred option


Shaun

 

normally doesn't get as good results as the vf's, but a capable turbo, would prefer to get the 18g myself for that bit of breathing space, well had i not got the vf34 lol

 

Wack this on it. More than capable.

i dont understand the different entry turbos. please explain

 

Front entry intake runs under the inlet manifold. Side is at the rear of the manifold.

 

Mine is a side entry inlet as you can see on the pic (black pipe leading to filter and maf)


Front comes under the inlet manifold.
