[litu]

To me that 2jz is soo lame and seen, this is more epic choice

[varg]

I was going to ask why someone would put such a very heavy lump of an engine in an E30, then I saw OP's name ;D

[ohrvik]

looking good :)

[Mr. Horsepower]

I have not done anything with the car for very long. So yesterday I got some things done. Removed the engine and started stripping it down for the rebuild/tuning :)

[Mr. Horsepower]

Okay, so, I have got some work done. The engine is now fully stripped down and I have made a deal with a engine shop to take care of the internals for me. And since he has a lot of work to do now, everything is on hold.

There is no rush when building something like this anyway. I have made a list for a shop in USA that sells almost every part that I need, so I'm waiting for a final quote on the price there.



The cylinders looks good, so there was no unpleasant suprises when I opened the engine.



Here is how each main bearing looked. I'm no engine expert, but there was only significant ware on the number 1 bearing.















Since it is late model R32 GTR engine, the crank has the long nose. Saved some bucks there!



One random shot of the crank



Started to take apart the head and placed the parts in order on the bench. Rest is up to the engine builder to take apart.





And a complete stripped block. Ready for wash, hone, deck and some drilling.





Till next time

[Mr. Horsepower]

Got some more work done on the build. I have also scraped together a order for parts from Eric's Performance Parts in USA. Can't wait to get some parts in the door so I can deliver the engine to the engine specialist.

The parts list that I have ordered is as follow:
-NPR Piston rings

So, to some pictures :)

Had an incident last year. The trackday tire did hook itself on the front fender and bent it. So I bought a set of fiberglass Sport Evolution fenders that I have had laying around since. I started fitting them this week, and they fitted very well. Just need to lay some new fiberglass on the left one to get it fixed onto the point that is under the low beam light. Also saving 2.4kg pr front fender.








While I was on the loft finding the front fenders I stumbled over my old stock E30M3 S14 gearbox crossmember. And that looks like it would fit the RB25 gearbox mount. The rubber mount will fit right on, so lets hope it might be the right hight for the gearbox as well.



Also received my R32 GTR Mishimoto radiator the other day. Was lucky to get one used from a guy in Norway with two dual fans and a expansion tank. It sits very well in the chassis. Just need to make some good fixing points for it.





Searching Ebay I found this HKS Type R oil cooler and filter relocation kit for RB26. This is the best HKS kit they sell with thermostat in the filter housing. So I can now remove the stock water oil cooler under the intake for good. This kit cost a shit load of money new from HKS, so I was not slow on making the decision for buying this second hand. Gave it a good clean when it arrived. Probably need to make my own hoses, doubt this will bolt right up.



Just trying some different positions for the cooler and the fan. Having the fittings in the bottom of the cooler is suboptimal, but as I said I was just playing with it. Probably will fix it onto the top of the intercooler when I buy that.



Till next time..

Wow, nice scores on the radiator and oil cooler, those look like very nice pieces.

[socalife]

Are you going stock cams and valve train?

[GDA]

Maybe missed it but what gearing will this thing have? Similar shift points and speed compared to the Euro S50B32 setup?

[Mr. Horsepower]

So. Have been working more on the oil pan. I have never ever tried to TIG weld aluminium before, so I had to give it a shot this time and try to learn it. I thought I got it going pretty well. It takes a lot of time compared to welding steel, that's for sure.

To start with I just cut out the oilpan to see if the engine would fit the car in the first place. Then I made some plates of 6mm aluminium and some half moons to close the holes for the driveshafts. After welding that on, The engine was crashing with the bracket for the steering rack.

In and out about 25-30 times I finally got it right with clearance and the engine placed in the middle of the car. Next step now is to start making the brackets for the engine mounts.

I also had to do some custom work on the JUN baffle plate. The sump became a bit smaller when I was finished, so the baffle plate would not fit as it was. So just some small mods and it was good to go.
The sump will be extended to both sides in order to swallow more oil.
I know the welds are not the art kind you usually see, but I like to do as much as I can myself and learn along the way.


Also got some more parts in the post. First to show up was the NISMO lightweight flywheel and the Cometic MLS gasket kit. Hopefully the rest will show up later this week, as well as the Mishimoto intercooler. Looking forward to place the coolers and everything.







Made some threaded aluminium bungs, and using the fixing ears that was already on the baffle plate.



Welded and is now fitting properly.



How it turned out. The dent you see is for the steering rack bracket.



Fitted in the car. Had to cut off a small bit off the bracket after this photo in order to get more clearance. When it was in the centre of the car, it was touching the bracket.





Don't mind the loose aluminium plate. It is just to have some millimeters of clearance to the steering rack.



Mocking up with a laser tool. My car have been crashed on the left side at some point, so I don't think I can use a cross measurement to place the engine. Best I have is the small hole in the front box there.



Probably need to convert to electric powersteeringp pump. I see VW Lupo/Polo and some other small cars have a very descent one.



And some new parts at last.





Till next time...

[Mr. Horsepower]

Wow, nice scores on the radiator and oil cooler, those look like very nice pieces.

Yes, I also thought that. Mishimoto intercooler is on it's way as well.

just...>> Norway spec

Hehe, good one :)

Are you going stock cams and valve train?

At first, I will. But will probably get some Tomei Poncam B and adjustable gears next year. Need that lumpy idle ;)

Maybe missed it but what gearing will this thing have? Similar shift points and speed compared to the Euro S50B32 setup?

To be honest, I don't know how the gearing is. It is 1:1 on 4th.
Box is a GTS-T R33 box, which is a RWD 2.5l Skyline. The shifter will be about 5cm further back than the BMW one. So I have to cut the chassis (fucking hate it) to get it through, and have a shifter that is custom. I want at least the center console to look standard.

In regards to power steering, one of the lads down here recently fitted his with a Holden (Vauxhall) Astra unit. Said it was very easy to fit and the steering is still nice and weighty

[Mr. Horsepower]

Got my Intrax rear shocks back today from Holland. They are now rebuild with remote reservoirs. No more rubbing the inner wheel arch, or hitting the fuel tank breather hoses on compression. A big thanks goes to Intrax for great service and customer support. Only thing is that you have to be patient.
