Project 'sillyteg'

[DreXeL]

If a jobs worth doing, its worth doing right... :/

I know, I know. But I have looked into it and a lot of people have had success with them, so I thought for £40 it's worth a punt.

At the end of the day it's not like I'm skimping of essentials like the turbo itself or the wastegate. If the BOV fails it'll either leak or stick shut, neither of which is catastophic.

 

[DreXeL]

That sounds like it would do damage, I have no idea, but wouldn't this build up allot of unwanted pressure?

No, the worst that would happen is a bit of compressor surge. Not healthy for the turbo in the long run, but as soon as it happens I'd know from the noise and stop boosting.

But if it leaks then surely that's gonna mess the fuelling and stuff up?

If it leaks it just won't make the boost it's supposed to, it'll just mean a loss of power, again not an issue and easy to sort.

 

[DreXeL]

Compressor surge sounds awesome, I'd run without a BOV permanently if it didn't strain the turbo so much..

 

[DreXeL]

Yep it's MAP on the Integra, not MAF.

 

[DreXeL]

You can do one of three things:

1. Get the supplied flange welded to a charge pipe.
2. Get one of these adapters that just attach to a piece of samco like any other BOV.
3. Get one of these, it goes between two charge pipes with couplers.

I'm just going to take a charge pipe into work and get the supplied flange welded to it.

Haven't really got any more done, I'm going to wait till my Golden Eagle head gasket arrives before I split the engine. I'm not working on it over the weekend either

But here, have some more pics of parts for now:

Dumptube/screamer pipe:

RC eng. 650cc injectors:

Intercooler kit (it's bigger than it looks in this pic, and plenty big enough for my power goals):

And the 'main event', the turbo :

That's most of the parts here now, still waiting on my catch-can, BOV, exhaust manifold and oilcooler/filter relocation kit. Oh, and the head gasket.

 

[DreXeL]

Yep, the screamer pipe attaches to the wastegate outlet to dump the exhaust gasses being bled by the wastegate.

 

[DreXeL]

Nice IC Ben. Looks a decent size.

Did you get the pipework to suit or did it buy it all custom?

How much did it cost you all in?

It was a full 'kit' to suit the Integra, only £250 shipped

Ben.....

You know where that screamer pipe needs to exit...

If you have it pointing out the closest bodypanel, ready to spit flames at the atmosphere I'll do anything. I'll adopt your dog. I'll walk your kids. Anything.

*n

Closest body panel would be either straight up out of the bonnet, or straight forward out of the grille

 

[DreXeL]

OK, after waiting a while for my Golden Eagle headgasket to turn up, it finally arrived and I've now got the engine built-up and ready to go back in the car:

(Sorry again for the crappy phone pics.)

As you can see, I'm going to have serious radiator clearence issues if I leave the turbo and dumptube in that position, so what I'm going to do is turn turbo around so the hotside/coldside swap places, this will bring the turbo much closer to the block and give me clearence infront of the rad (I have bought two slim fans for the rad already). Obviously this will mean modifying the downpipe so it is the opposite hand, but that's no biggie. I'll then also have clearence modify the dumptube so it faces straight down.

Hoping to get the engine back in tommorrow.

 

[DreXeL]

Looking good.

Nice Blox manifold. My GT28RS is just clear of fouling the block with the compressor on the drivers side so I dduno what yours will be like with you're T04E housing. Maybe you could space the manifold from the head with a plate, whats the wastegate clearance like between the cam cover?

There is no clearence between the wastegate and the cam cover, it's just touching. I may make a small spacer plate up, it would ony need to be about 2mm thick. I've had to trim away some of the block to clear the housing when fitted the other way.

That screamer isnt really ideal asside from the packaging. It will end up with exhaust gas being ingested by the compressor aswell as making your engine bay a state, much better to route it rearwards under the car and maybe include a exhaust driven crankcase breather, so on high boost you have that sucking air from the port on the rear of the block (slash cut fitment in the screamer) to stablise the crankcase pressure.

Yeah the screamer will be modified somewhat. I've been reading up about the slashcut breather thing on H-T, I was just going to run two breather tubes from those plugs on the back of the block into a breather catch-can, but seeing as I'm going to be modding the screamer tube anyway it would make sense to go with the slash-cut thing.

The plan is to have it ready for Japfest, it's going to be tight, but I should do it.

I have one track session booked, 11:30 IIRC.

 

[DreXeL]

Somewhere between 300-350bhp. The integra puts the power down pretty well anyway, thanks to a good LSD and well designed suspension (equal length driveshafts etc.). There are nutters in the states putting 750+ whp through the front wheels of Hondas....

 

[DreXeL]

I'm probably going to ditch that filter and T a hose into my main breather tank.

Any chance of blagging a passenger ride for your track session (cheeky I know!)

It looks like it's already taken I'm afraid buddy, but I'll let you know for definate nearer the time

 

[DreXeL]

Ultimate Jap, our stand is right on quarry corner

 

[DreXeL]

It wouldn't exit there though, it would exit at the front near the Honda badge. Which would look kinda gay.

 

[DreXeL]

Screamer out the side of the front bumper, about 6" in front of the offside wheel.

*n

Don't tempt me to do silly things like that

 

[DreXeL]

It would be fairly easy to do aswell

Won't it, like, melt my bumper though? I suppose it would be OK with a heat shield. Hmm.............

 

[DreXeL]

Of course it'll be tracked, mainly at Castle Combe where they rarely have drive-by noise testing, and the wastegate won't open during a static test so it should be fine. Besides, it's only a 38mm wastegate, 38mm screamers aren't that loud.

As for the MOT, that depends on how friendly the tester is

 

[DreXeL]

Ramhorns are awesome but I didn't want to lose my A/C and P/S. My manifold is an exact copy of the Blox cast manifold (which is proven to work well), but only cost me ~£100 shipped.

Cast manifolds aren't pretty, but they work, and give better spool characteristics than tubular manifolds. Sure, they don't ultimately give as much top-end power as a tubular items, but you can get over that by turning up the boost

 

[DreXeL]

By how much though, an actual noticable measurable amount?

Just not able to heatwrap it to get around this if it is a problem?

As penski said, it's not just about heat, it's about distance and total volume to fill before the gasses hit the turbine. In a small cast manifold the gasses have bugger-all distance and volume to fill before they hit the turbine.
