Anyone suggest the best way to upgrade the DR30 intercooler?

Should I just fit a new frontmount or is there an upgrade available to replace the std intercooler with a better one while retaining the std position in front of the left wheel?

I'd prefer to keep the std look and avoid too much cutting but not at the expense of efficiency

Cheers

No upgrade as such, but R33 standard intercooler is good for about 300hp.

If you look at the pics on the now, my track car thread, the intercooler on that had the air con still intact & all that was lost was the headlight washer pump.

The inlet is on the bottom, that's why it's hard to see. I'm going to put it in the PNV and use a crossflow too.

I recently bought a Delta Fin Intercooler, they are lighter & flow better than conventional bar and plate construction. The one I bought is big, 600 x 300 x 78 & flows 1020cfm with a 0.2psi drop @ 20psi boost & good for up to 900HP. But that is for the track car.

600 x 300 x 76/8 isn't necessary for a street car, it's an over kill if anything.

My mate here has gone the smaller of the 2 china cores available fits in pretty nice and snuggly in between the headlights with minimal chopping

Where I have gone the larger, which to get to fit was a bit of a bitch. Welded 90 degree bends on the ends to get it in a little tighter with a bit more chopping necessary. To tell ya the truth I really should have just gone with the smaller option as performance gains would be minimal in comparison.

The ebay kit is the large version. It's 600 x 300 x 76 (24" x 12" x 3" old school) I think what Josh is talking about is approx a 400mm core length, but I'm amused as to why both are mounted with the inlet & exhaust at the top instead of the bottom where a large majority of the space needed to fit them is under the headlights on an Iron Mask front.

Got my car back from the panel shop finally and was checking intercooler space.

Not too keen to cut the hell out of the centre support so may look at a 600x150 intercooler mtd low down in the airstream.

Seems to me only the lower half of a 600x300 would work in a street car anyway

Another option is a Water-to-Air IC. I'm using a PWR core in place of the OEM x-over pipe (my car is an '83 RS-X so it was non-intercooled).

I've just upgraded my pump to use a Bosch unit, and am using the air-con condenser as the heat exchanger. The next step is to fit a reservoir of about 5L to increase the capacity of heat-sinking that the system can cope with.

I'd post photos, but it's all apart right now with the pump upgrade and reservoir installation...

      Blue/grey smoke after idle

      I get that taking off the head is best but that's a bit much for "just" valve seals. I was just under the impression that one would be able to rotate to TDC and be able to temporarily drop the valve without losing it and effectively having to remove the head to then recover it. I never knew people actually pushed rope into the cylinder to do valve seals hahaha So just to confirm, just going to TDC will not work? In that case I know when I do valve seals I'll maybe just remove the head and do some other things while I'm there, or just wait until I do an engine build.

      The old approach was to fill the cylinder/chamber with a length of rope pushed in through the sparkplug hole. The new approach is to connect compressed air to the sparkplug hole and fill it with enough pressure to push the valves up. Doing either of these things with the head on and the engine in the car is a lot less pleasant than doing it properly.

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.
