hello mates

im about to buy a VF35 turbo as im gathering all the parts for the conversion.
so far i have the walbro fuel pump and the Haltech ECU will follow on over the next few months when i get the funds.

Currently the car has a full decat magnex with H&S downpipe,green panel filter and a greddy boost controller all fitted(i believe this will go if i run a full aftermarket ecu?)

Can anyone thats done this upgrade tell me what else i will need, is it right that the 440 yellows that are standard should be ok and the TMIC should aswell as im aiming for around 320bhp as i want to keep it safe or do i need to upgrade to 550's and a STI8 top mount?.

Are there any other bits(pipes/fittings etc) i should get along with the turbo or is it just the unit alone i need at this stage, sorry for all the q's

many thanks for any replys

Barry

You sure its a VF35 you're selling ?

A VF35 is capable of more than that, and will not be as fast as a P1's VF24 to spool. VF24 will struggle at 300+. It is a nice fast spooling turbo though, but no real use for making power.

Boost controller will stay when using an aftermarket ecu. It just simplifies everything, and allows the user to retain some control over the boost.

Unless of course you want it removed.

440's will be fine to 320, although ideally 550's would be better, and leave room for the future..

A better intercooler would be a wise upgrade, but depending on driving style, not essential. If you intend thrashing the life out of the car, then you will most definately need a better IC, bigger is better.
If its just the odd blast now and again, with no sustained hard use, then you will get away with the std IC ok. Of course it isnt ideal though.

If you can source the parts at the right price...it would be silly not to upgrade. Otherwise, just drive sensibly until you can upgrade.

Shop around, check ebay etc.....you might just get lucky !

cheers stevie, yeah i was wondering about the turbo? i thought a VF35 is good for 350 at a push and spools a bit later than the td04 i have at the min.

I really dont drive the car hard, it never gets launched or anything or prolonged periods of flat out driving just a blast now and again, michael will be doing all the work to the car so im sure he'll tell me if i should def go for the other parts aswell, might put an sti top mount on and the 550's for safety as ive seen them on here cheap enough

its the gearbox thats gonna be my weakest link i think though, some seem to be able to handle in excess of 350 and some go at less than 300! i should be somewhere in between that, but im not harsh on it...suppose its that chance you take

Cheers

Gearbox will be on borrowed time at much above 300. As you say, some last a long time, some dont. A lot boils down to the driver.

VF35 would be good for circa 380 or so.

The VF24 fitted to a P1, will spool about the same as a TD04, but continue to make a bit more power at the top end. A little over 300 or so.

If buying injectors, buy from a reputable source. Dont buy crap, or you will have to buy again.
I think the 740's are reasonably priced, and work very well, and will leave plenty of room for the future, if you ever wanted more.
Speak to Michael and find out, as he defo got some more just recently.

i was trying to stay around 320bhp/300lb/ft as i dont want to run into uprating engine internals,plus try and prolong the gearbox i hear warrens car has standard internals i dont know what sort of power he is running, but ive seen it go and it really does shift, suppose alot depends on how its mapped.

Just because a turbo is capable of supporting a certain power, doesnt mean you have to push it that far. The larger turbo will just be more efficient in the power goals you seek, rather than a smaller unit screaming its ***** off.

Warrens car has something crazy like 130-140k on it now !!!! totally untouched UK engine with bolt on goodies. His box lasted quite a while, although broke at SSO in 2006. Munched 3rd gear.

yeah i think 320-330 will do me fine and make a very capable road car, i like to keep the sleeperness of the turbo 2000 as well.

standard turbo on a p1 is a vf28 not a 24 this turbo went bank on me so i bought a 35 it was a great wee turbo but was only capable on of 330 or so bhp. soi went for a vf30 which has the best of both worlds

VF28

This turbo came standard on the STi Version 5. In terms of overall size, it is smaller than the VF22, VF30 and VF34, and about same size as the VF23.

VF30

The VF30 is commonly considered the best bang for the buck turbo in the IHI VF series line. A relatively new model the VF30 features the same exhaust housing as the VF24 but a larger compressor side similar to the VF22. The combination of these two parts results in increased output potential without the lag associated with the VF22. Although it doesn't offer the top end supremacy of the VF22, the VF30 is a great compromise between these unit and the quicker spooling models.

VF35

VF35 The VF35 has identical internals as the VF30 and it uses divided thrust bearings. However, the exhaust housing is a P15 which means this turbo will have fantastic spool characteristics. This turbo is standard on the new WRX Type RA. LIMITED SUPPLY

Im hoping to get around the 350-360bhp mark with my car, Im going the Haltech ECU route as well as yourself Burt2000....think Warrens car goes really well by the chat of Michael, but i hear one of uz saying there he munched 3rd gear?? .......I thot he had a 6 speed box and they were fit for bags more power than 320/330bhp??

As for a turbo I was going to go the andy forrest 20g jobbie but Michael thinks there are better alternatives than this at around the same money ...has any of u guys got an andy forrest 18/20g???? Are they a good job??

Much as I hate to dissagree with you Stevie the vf35 will never flow 380 or even 350 imo
The gearbox however (using a type r v3 dccd) as an example stood upto 350 with hard launches and track time effortlessly even running an 11.97 quarter .
Horses for courses I suppose
Just using my own experience as an example

A555K

fao rb5 boyo, warren munched 3rd in his 5speed, then he bought a 6speed

RB5 Boyo

Aw rite rite, nawt so bad then, i was worried that the 6 speed wasnt strong enuf to cope lol

are you keeping the standard box rb5 boyo?I cant afford a 6 speed your talkin the guts 2 grand there, i wonder are the type ra or type r boxes stronger than a standard uk box

also how do you feel about standard engine internals at 350-360bhp?

ustolemyname??stevieturbo

When you consider the cost of swapping to one of the STI type boxes, which will also mean a diff swap.....and they really arent that much stronger. You do need to consider the 6 speed option.

Warrens car probably lasted for 30-40k after being tuned on its UK box. It ran a best of 12.2, and did plenty of racing before breaking. But he is not a harsh driver by any means.
So a box that might last one person a long time, might last a day or 2 in someone elses hands.
I know I managed to break my old Legacy box doing 1 launch, on the road, in the wet.....Of course it had received abuse before that, not not too many hard launches.
But I guess sidestepping the clutch at 6000rpm is never a wise idea lol.

And then you would have to stick with the horrible short STI ratios for daily use. Good for racing about etc, but not so good for milage and day to day use.
But yes, a good STI box is a little stronger than a UK box. But long term, the 6 speed is hard to beat.

I havent seen too many 5sp upgrades ( which will cost more than a 6sp anyway ) stick the pace either. Ive heard of far too many PPG etc failures of one kind or another, that would steer me away from that route.
6 speeds by comparison, for a std box, are bloody strong !

my scoob isnt a daily driver but i really dont drive it hard or be aggresive with the box, so at the power im aiming for am hoping it will hold up ok, i just want a bit more power not going to mad with it.

RB5 Boyo

Awh im gona bite the bullet in the new year hopefully and get a 6 speeder cuz after speaking to wans who have went down this route it seems the only option ....and like yer man says there, to fit the sti box u need the shaft and diff etc anyway, and i got quoted £700-£800 from Mc Keevers breakers for an sti box and diff....and thats in exch for my old box and diff!!

My engine was rebuilt 8 months ago by OMA and has got a few wee nice bits inside like a later version crank and pistons etc, and iv only done roughly 2500 miles since the rebuils (only drive the car the odd evening and at weekends)so im gona see how it holds out but i'll see what Michael thinks when i really start upping the power!!
