Rb25de (supercharged) Project

[TiTAN]

One of the 2.8L jobs to get you to about 800-900hp and then throw a 2000hp turbo of some kind to take over.

that would be one nuts skyline

[r33_racer]

Yeh, its probably better suited for a rail or tube frame car. More room!

I should make a fancy coil pack cover with the new designation on it....mmmmm Cheers for the idea Will!

So long as you make the new coil pack cover so it reads "RB25...DER!"

looks nice

pic related, if you know what you're looking at

some toyota engine? camry maybe?

some toyota engine? camry maybe?

Camry is FWD thats looks to be a RWD im guessing 2JZ supra.

[Adriano]

Or 1ggze with a turbo

[Rowdy]

1jz twin charged?

[r33_racer]

Something twin charged, thats for sure. Looks like the turbo feeds into the supercharger, which looks like a factory unit, probs the one of the 4agze?? Or maybe they merge together, its hard to see.

Looks quite intricate though.

Im working on the merge collectors today and then onto the rest of the headers. I have holidays this week and I hope to get this part close to done this week!

[XRATED]

Wow... I want to work where you do. RDO's, holidays and "personal" time at work... I LOVE IT~!!! ha ha ha.

Get those headders done pronto!

Coat them

and start that fkr up!!!

Twin charged 2JZ

The supercharger feeds into the turbo (not how I would have done it, but far less piping I spose) to minimise lag.

and here's a pic of the turbo before it went it

[r33_racer]

Thats insane! Looks like it will rip some mean skids! Where is it located?

Here are the two merge collectors ready for vband rings, which I dont have yet...Anybody know of places that have 2.5" and 3" vband rings with clamps?

Got them expanded down the road at Macs Mufflers at Brendale! Did it while I waited which was good. Cost me $30.

Time to clean up the insides!

Haha good stuff!

Perkies all the way

[TiTAN]

an exhaust shop should be able to get hold of them for you i would have thought.

[DRD-00F]

In a super secret workshop somewhere secret

[r33_racer]

All the merge collectors I found that could be bought from an exhaust shop were not proper merge style ones. They were the old fashion way with pipes tacked together and a conical sheet rolled around it and then shaped around the pipes and welded up. I wanted to this bit properly and challenge myself....it did take the better part of today though. But it was my first go at doing this....surely thats a good enough excuse lol.

Good thing GCG has the vbands! Woot! Problem solved.

[TiTAN]

have you had time to get any further with the exhaust?

[r33_racer]

Actually I have done abit. I havent bothered with a proper update yet as I never got the exhaust finished. I have done the extractors and down to the 2 into 1 merge and left it at that for the moment. As of today I have the motor and gbox out and the bottom end stripped for inspection and a few mods and tweaks to be done before it all goes back together and then back in.

I didnt go into any detail in making the headers like I originally wanted. They are far from equal length and abit messy. It took ages to do and it was a pita. I couldnt make it equal length or close too like the UK guys did in their race car because I still have heater lines and wiring and other crap along the firewall and so had to place things differently. But as you will see from the pictures 1,2 and 3 go where they need too inorder to clear the intake and 4,5 and 6 basically go straight down into the collector. The other main hold up before coating is my egt sensor setup from america is being held in customs as it was over 1k I gotta fill out all the bullshit paper work and go pay the extra tax before I can collect. Once I get them I can weld in the fittings and paint the whole thing or maybe get it ceramic coated and then heat wrap it all and have it ready for installation.

The motor looked great when stripped down. I rebuilt it like 3-4 years ago and since then havent looked after it very well, gave it shit oil and hardly changed it. The oil that came out of it was quite black and burnt. Yet the bearings were damn near perfect apart from a few polished areas on some, but the majority were still with factory coating and discolouration. I was amazed as this car hasnt been treated very nicely when it was being used. Many burn outs and thrashings have been given over that time!

So I gotta do a few adjustments to the factory oil pump and then some new seals front and back, fit the twin plate, possibly modifying the std sump to hold a couple litres more oil, reassemble the bottom end and then chuck it in and finish off the exhaust and fuel system side and hopefully try and get it started! With any luck I wont have a million things to try and fix before it runs reliably.

Thats about all I got for the moment. Once I get a good amount accomplished I will post up a big one!

[XRATED]

Nice one Mitch!

"They are far from equal length and abit messy".... bahahahahahah yeeer messy.

What egt set up did you go with??

Cheers
