i know this has probably been asked a thousand times but whats the better option to go for?vf34 or 18g !?!? i have no intention of uprating internals or gearbox, just clutch and maybe flywheel.
ive got every other supporting mod to match these turbos
just want peoples experiences of these turbos on a wrx
i know 18g will be a bit more laggy but is it worth it for the top end rush?

You have more options in relation to the 2 turbo's you have there and cheaper too, so look at the vf35, vf48, hybrid TD04 as well as the above.
Also what are you aiming for power/performance wise
Oh and you will probably need to upgrade your injectors as the same time.

yeah got a nice set of sti pinks waiting to go in same time as turbo and new remap.been looking at other options too like you say,but i think ive whittled it down to the two i mentioned.looking for as close to 350hp really,but still want it running nicely within the parts limits,so would be happy with 310-330hp on 278hp at the moment.

I had vf34 lovely spool and nice sounding as well make a nice punchy snappy road car

VF34 probably not as powerfull as 18g but, you get much more usable power, as its power band is very long... 18g has this old school type of kick up the **** and when it does it it feels great... But the spool is much later than the vf34... VF35 is a gret turbo as Tony mentioned , quick spool = quick raod car... Numbers dont nescesary will make a faster car , dont be fooled .
Personaly vf series all the way, or even better SC range...

I am definatly swaying towards a vf34,but also been looking at the sc's.would you rate them better then?

I've gone from a 34 for to a sc 46 on a 2.0 non avc and its not even got a full map on just running in map and it's mental spool is great I have the billet sc46 great turbo

Theres very little in terms of spool difference on a vf35 to an 18g. 2 or 300 rpm in my case as i went from the 35 to the 18g. If your not going to be uprating gearbox etc id stick with the vf35. The 18g will give a fair amount more power. but ofcourse theres risk of blowing the box up. Im my case the vf35 made 330bhp the 18g 380 on v power and 401bhp with 20% meth. Only other changes was bigger injectors for the amount of fuel needed for the meth map

id be interested in to see which way you go with this mate as its something im looking to do myself very shortly. Keep the thread updated once you've made a choice on it

its done! just bought the andy forrest td05 18g off dawn from harveys collection of bits. brand new 18g for £600.im a very happy man right now just wait for it to arrive then fit her

was that on wrx standard internals you was running 380? im not to worried about gearbox to be fair as im not a crazy driver just love the power to be there.dont hammer my car.......much lol

when are you planing on fitting the mods mate? would be good to see your results before making a final decision as i maybe able to get hold of a vf34 locally.

thats a cracking price on a brand new unit btw!

just noticed your in Bracknell, theres a few of us in and around Reading mate, you'll have to come along to our next meet

i know im happy with price thanks,
will be on within the next couple of weeks.will get a dyno print out up on here when its done if you want.you live in reading then?

yeah sure il pop along! when and where you usually meet?

Both good turbos, but the 18g might be a bit too powerfull for the wrx box as the 18g will have more tourque and that's what kills the box, I see you have now bought one, advisable to get it mapped to a reasonable level without going too high.
I have the 34 and it's a nice turbo @ 330 drives well on road with less amount of lag so useable power for a road car.

yeah im not gonna max the map out,still gonna be sensible but to be fair will probably end up with a 6 speed in her within the next few months! lol

ah cool, who's doing your mapping? yeah post it up it would be a good comparison.


our next meet is on the 3rd February (this sunday) at the Travellers Rest in Caversham. we've got all of our events on our facebook group/ drop me a pm and i'll send you the link

scoobyworld done my current map which im happy with, but might be going to eurospec in guildford for this one..not sure yet.
will pm you now then mate!

whats the upper limit of a 34 mate?

Then max it, when box goes replace it if your planing to anyway.

still deciding to be honest.what power can i expect, 320,330,340? or a bit more? roughly

No standard sti

Id say around 330-350 max dependant on mods, but a good useable turbo
Id aim for 330-350 max to protect your car, id say the 18g will do 360+

just out of interest how does your car feel with 278bhp? Compared to standard? Which mine is (225)

It's a fairly big difference to be honest, I was really happy when it was first done but I'm always one to want more lol would recommend you too do it for sure will put a huge grin on your face!

Nice one Jake. Thanks for reply.
Will be going for about 280. rear box already changed from twin pipe pea shooter to prodrive one . To loose all cat and replace with a ppp sports cat. Plus 3 point sol and panel. And maybe a upgraded fuel pump. So should feel the difference then

Yeah 270 -280 is achievable for a stage 1 tune, I'm running k&n typhoon induction, 100 cell ninja sports cat,decat centre and raptor backbox. plus a decat up pipe(which is essential) and a 255 fuel pump with ecutek map. Yes you will certainly feel the difference! Lol best of Luck and have fun then :-)

Any chance you could get a vid up of the raptor back box?

Cheers harri

Sounds good.
