Swoggles Posted October 19, 2016 Share Posted October 19, 2016 Hello, I'm going to be fitting a vf48 to my 05 wrx and wanted to double check some information. Firstly are all gaskets the same? Secondly I have read that the coolant lines aren't a straight fit. Do I need hatchback coolant lines or can the standard ones be modified? Cheers Quote Link to comment Share on other sites More sharing options...
quit Posted October 19, 2016 Share Posted October 19, 2016 the vf48 is designed for the more torque 2.5 lump so might not be as fantastic Quote Link to comment Share on other sites More sharing options...
Swoggles Posted October 19, 2016 Author Share Posted October 19, 2016 Wouldn't it just be a tiny bit laggier than if it were on a 2.5? Quote Link to comment Share on other sites More sharing options...
aucky Posted October 19, 2016 Share Posted October 19, 2016 why did you pick the vf48? Quote Link to comment Share on other sites More sharing options...
Swoggles Posted October 19, 2016 Author Share Posted October 19, 2016 Mate was selling it and it made 400 on his 2.5. I know it's a different engine but surely it will be ok? Quote Link to comment Share on other sites More sharing options...

Sandals Posted October 19, 2016 Share Posted October 19, 2016 You will def need bigger injectors as well... Quote Link to comment Share on other sites More sharing options...
Swoggles Posted October 19, 2016 Author Share Posted October 19, 2016 I have a fmic, air filter, 3" zaust with decat, fuel pump, dark blue hawk injectors, forged rods and pistons and a super awesome innovate scg-1 . That should be sorted to 400, although I am on a 5 speed so won't be hitting that. If it doesn't work I'll have to sell it and get something else on. Just needed to know about the fitment for the snail incase I ended up waiting for parts. 1 Quote Link to comment Share on other sites More sharing options...
quit Posted October 20, 2016 Share Posted October 20, 2016 350ish your gearbox will go bang! all of that mapped on a td04 what power you pushing out the little 04? about 290? Quote Link to comment Share on other sites More sharing options...
Tidgy Posted October 20, 2016 Share Posted October 20, 2016 O sack off the SCG, not needed, ECU controls the boost. Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted October 20, 2016 Share Posted October 20, 2016 I dont know much about the spec of a vf48 but If the 48 has a roller bearing core, Think you might need the coolant / oil lines and the oil feed banjo bolts of the 48 . As the tdo4 has journal based core and requires more oil than a roller bearing cored turbo . If that's the case you stand a good chance of blowing the turbo seals without a more restrictive oil banjo bolt than the original tdo4's one . Afaik all single scroll oe subaru turbos use the same gaskets . You'd need a new up pipe to turbo inlet and turbo outlet gasket when fitting anyways. Make sure you buy genuine subaru ones and most buy them from import car parts, so just double check when ordering them [emoji6] Quote Link to comment Share on other sites More sharing options...
Swoggles Posted October 20, 2016 Author Share Posted October 20, 2016 Not sacking off the scg, useful gauge to have in my opinion. Doubles as a boost gauge and an afr gauge. Also I'm on ppp performance at the minute, so 260 with the tdo4, not particularly fast although she handles exceptionally well. I don't think the 48 is a roller bearing, I'll have to double check this. I was going to make a list up on icp after work, as far as I know I'll need; manifold to Up pipe gasket ( ordering a harvey up pipe) up pipe to turbo bellmouth downpipe gasket and Two 3" zaust ones Do I need any for the coolant or oil lines or are they just copper washers? Cheers for the help so far guys Quote Link to comment Share on other sites More sharing options...
quit Posted October 20, 2016 Share Posted October 20, 2016 Running all that on a unmapped ecu ?? 😳😳😳 Quote Link to comment Share on other sites More sharing options...
Swoggles Posted October 20, 2016 Author Share Posted October 20, 2016 No that would be a silly idea haha it will have some parts fitted then be mapped. Then when I'm not so poor some more bits can go on, I dream of spare cash to buy a 6 speed at the minute. Quote Link to comment Share on other sites More sharing options...
quit Posted October 20, 2016 Share Posted October 20, 2016 Yeah your gearbox is limiting factor mate Quote Link to comment Share on other sites More sharing options...
Swoggles Posted October 21, 2016 Author Share Posted October 21, 2016 I know I'm to poor to consider a 6 speed at the minute. I do like the gearing of the 5 speed though. Massive shame the only real option is a 6 speed swap. Hopefully the box lasts a little while at least. This modifying lark has gotten a bit expensive Quote Link to comment Share on other sites More sharing options...

Scoobyghost Posted October 21, 2016 Share Posted October 21, 2016 Stick some bracing on the outside of the box. It'll stop it flexing so much and may make it last longer. Quote Link to comment Share on other sites More sharing options...
Swoggles Posted October 21, 2016 Author Share Posted October 21, 2016 I don't think that's really the problem. My personal view is the internals are simply not up to the task. Weak shafts and gears is what I think the problem is. But finding actual evidence of what breaks them is tricky, it's all opinion from what I see.

Scoobyghost Posted October 21, 2016 Share Posted October 21, 2016 With the extra torque the casing flexes allowing the gears to slightly separate. Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted October 22, 2016 Share Posted October 22, 2016 There is a company that sells the 5 speed gearbox strengthening plates which are supposed to help but like the op I haven't seen too much evidence to support that they work well . You can buy ppg gears sets which make the 5 speed much stronger but they cost about the same as a 6 speed just for the kits (no labour inc) . I don't think that you use the strengthening plates while upgrading the gear sets either but I don't know much about them as I went 6 speed instead . Your blobeye will have the slightly stronger ty54 5 speed so if the mapper keeps the torque down you'll probably be ok . I wasn't aware that any oe subaru turbos would hit 370hp on a 2ltr engine anyways ? Quote Link to comment Share on other sites More sharing options...
quit Posted October 22, 2016 Share Posted October 22, 2016 Rotherham Scoobies will be offering a upgrade spray soon for £359.99 it looks like hairspray and smells like hairspray but it isn't and he will gaurentee that 2 Quote Link to comment Share on other sites More sharing options...
Swoggles Posted October 22, 2016 Author Share Posted October 22, 2016 Upgrade spray? You've lost me. It's. Got to be 6 speed really. Have to start saving. I'm not sure what power it will make, get some boost in it and see! Quote Link to comment Share on other sites More sharing options...
