got another question about cams. didnt want to waste space with a new topic.

i have found some replacement cams.

they are: 270duration and 10.25mm lift.

now i can get these in both exhaust and intake,

but if i stick this size on intake how will it run?

will it run like a dog?

i heard u need a different size on the intake?

Go for a GT35-66R with 0.82 rear. It is a GT35 with T04Z compressor wheel. It has a 66mm inducer compared to 61mm on the compressor side. Essentialy it is a "high-flow" GT35, that will be more responsive than a T04Z and make similar top end. I know GCG does them, not sure who else does.

I had 272's on both exhaust and intake with extensive head work. Sounded tough on idle but would hunt like a pig driving around, became something that started to be annoying to "go for a cruise in".

Turbo was a td06-25g base with t78-34d wheels and rear housing (dont ask me why, it came on the car), something like 1.0 - 1.1bar at 3800rpm and 490rwhp on pump at 1.5bar. The guy I sold the car to has had the motor on an engine dyno and made 720hp at the fly at 2bar IIRC with alot more tuning and playing around.

I have no idea if you "have to" run different size's on the intake, I just know althought my car was streetable it was a pain in the ass to drive off boost around town.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      The cam I am actually putting in (a few posts up) is actually smaller than my current one. At least duration/overlap wise. All the chop stuff I hear just sounds like an engine running badly, because it is. I then envision driving it around in 1st gear and being massively sad about it bucking to the beat of said chop. There is an idle video of someone with a similar cam floating around the internet, but mine is a custom cam (so is his) so it'll never be the same, plus the fact exhausts are entirely different. What I want to do is put some bullet mufflers/race mufflers in to replace a couple sections straight pipes that currently replace the two extra cats that I don't need. But this is even further down the line!

      I can tell you now, when the bracket that the little hydraulic ram attaches to snaps, with a subframe, and V8 from an AMG C63 on it, it sounds like someone letting shotgun off right beside you. It leaves your ears ringing, and a huge thankfulness that you never ever put a body part under something heavy that's only supported by a hydraulic lift...

      Water leaking into the rear trunk

      By Neostead2000 · Posted

      Still not a guarantee fix. I used a high quality butyl-mastiq (the black goo that's not really silicone nor polyurethane, same stuff they use from the factory that just spreads out like melty cheese), and I still get lots of water on both sides of the trunk when raining or washing the car. I also suspect the factory spoiler rubber gasket might not be sealing well, so I'm thinking of adding a thin layer of grey silicone around the bolt holes on both sides and see if that's where it also leaks from. The biggest issue is that these cars don't come with a drain hole on each side like other coupes and hatchbacks.
