Ep3 Turbo build (plus some other honda stuff)
Just started this EP3 turbo build, we are currently waiting for parts (turbo spec was changed).
We are going for around 400hp on the stock engine. The car was around 240hp when it was dropped off with us.
This is the turbo we were going to use but decided to downgrade to something a little smaller.
Intercooler pipes are done as far as we can without turbo.
So is the intercooler. I flow tested this against a vertical core and this gave the best results. (will post pic's when I get them of the PC at work)
I've never seen an intercooler done like this, so remember, you saw it here first
3" exhaust to make next week, while waiting for the turbo etc to turn up, then the manifold etc when it gets here

Welding cast isn't a problem, but heat and welding cast can sometimes have issues. I've done various turbo's and manifolds in the past and never had a reported problem. But there a pain in the arse to do at times.

I know mate, that's why I am laughing...
There is no way on planet earth that car is making a proper 420bhp at the wheels. I'd love to see what the dyno graph that I've heard backs up the claims looks like!! I've seen the thing go remember and it drives like it's got about 275whp, absolute max. So I assume that up to 7000-ish rpm there isn't much while the turbo spools, then he gets the extra 145whp in the final 1200-ish rpm before redline?!
Also, forged or not, rolling around giving the car stress while unmapped is a dangerous game to play.
Cheers,
Grant

Taking the exhaust under the rear arm isn't practical on a road car IMO.
On the EP3 there a lot more than the b series.

Yea that's what I thought when I heard 420whp without being mapped... and after I saw the thing getting stress and not shifting anywhere near as quickly as a true 420whp car should, I seriously doubt the claim.
Brilliant. ...I'm not sure if you've had any experience or contact with a TTS Rotrex Supercharger equipped EP3/DC5 before Ricky, but if you have, how do you think this Turbo kit compare driveability-wise??

I thought tripple the power was an acheivement when we first did it a couple of years ago, how foolish all the hours i spent mapping it.
Anyway back to this car. Exhaust is currently been done, still awaiting the turbo. Will post pic's of the exhaust later.

I might be tempted to go back to a Teg or Civic turbo tho as the Tein coilovers on the Evo are a bit harsh & my G/F does nothing but moan about it and on the baby's neck.
Did you ever get your EG finished?

My EG's in a million pieces ready to paint etc, its nearly finished parts wise. Spec is somewhat bigger than before. Its virtually a full carbon body now. Removal alluminium front end, double diffuser. Sleeved b18, GT40 custom spec turbo. Hoping for 700hp and 700kg's.

I've got a 6 also, theres something about the fwd honda's that makes you though.

We'r still waiting for parts as we changed the turbo we planned to use. I'm hoping to get the new turbo by next week. The exhaust and a few more bits are all made but no pictures because we took it off the ramp before i took any. Updates next week i'm sure.
Sorry, not yet, body work is pretty much all carbon. Its only half finished. But we've removed 150kg's from the previous weight 830 kg's (probably added some bits here and there though).
Power shouldn't be a problem, everything is spec'd for 1000hp but we'r going to run the small turbo for now... GT40 Progress has been slow as i've not moved it to the new garage yet. Soon as I do i'm sure we'll gain momentum with it. The problem is it usually ends in more things been cut off and less things been attached.
Heres 1 pic.
To add a bit of colour a few pictures from this week.
B series ram horn.
This should be around 600hp, its currently done an 11.8 at TOTB (road tyres) last year. Since gone bigger turbo, 1 of our inlet manifolds and a few other bits. We don't do everything on this car, there a few things we would do a little bit different. (silicone joiner flexy pipe to turbo etc)

I'm hoping it'll go around the track*, hence the aeros and small turbo (full boost on the last lower spec engine was 4100rpm's (2.1 bar))
It will certainly not go to plan as you know, there are a few quick car's this year we'r involved in, hence me taking my time on my own.
I'll post a seperate thread at some point.
* In an insane undriveable but fun way.

Exhaust is all done and has been for a couple of weeks, but didn't take any pictures while it was on the ramp.
Still waiting for the turbo from the states. Should be here by the end of next week, there currently on back order at the moment though. A shame the customer decided to change spec at the very last minute.

Seen the videos of the yellow ep3 on YouTube, brave man to be doing that with a unmapped engine. When its racing the pulser it sounds like he ended up with a misfire. Ricky what is your customer using the car for, track or drag? If it's drag I know of a quaffie dog kit forsale
