Hey guys, just bought myself a 1993 r33 gts-t in what I thought was mint condition. It looked great, sounded sweet with the hegh flow cat and 3" cat back hks exhaust. It wasn't till I got it home that I found out the knob 2 owners ago had overboosted the standard turbo and melted the wheels. I had to pay a bucketload to get new steel wheels, new housing, and wastegate actuator and while I was at it I got it high flowed. Next came the dump pipe. It was at that stage I found a massive power loss at about 4500-6000 rpm. After exhaustive search on the net and lots of trial and error i found out the AFM was shot. Thats getting fixed now and I have run into my next dilemma, WHAT TO WASTE MY MONEY ON NEXT...

I know I need a fmic but need to know what is best and on the cheap having spent way too much already.

Is bar/plate better or tube/fin design. I also want to do the install myself as my mech "friend" has already taken about a month to get everything sorted (In total I have only driven the car for about 2 weeks and am sick of my POS ford laser).

Any suggestions would help.

My mods are:

High flowed steel wheel standard turbo

3" stainless dump pipe

High flow cat

3" HKS cat back exhaust

Turbosmart Boost controller (only running standard boost until afm fixed)

All the rest is standard atm.

There's nothing wrong with the hybrid copy intercooler. Pick one of those up for approximately $170 delivered to your door step and then take your selection at a piping kit which would cost you a further $350 or so. Either that or look on Ebay for some of the packages they offer

i like these coolers and piping.. there hybird coolers.. custem made pipeing.. give them a call!

You had the turbo "highflowed", then fitted a decent dump and at that stage this power loss occured between 4500-6000rpm.

How positive are you that the cause is the AFM? Because it sounds like a textbook case of the ecus rich and retard strategy.

Did you try turning the boost down? Did it still happen?

Thanks for the info guys.

I am 100% positive it is the afm cuz the problem disappeared when I borrowed a mates s1 afm.

Boost is currently at standard.

I only noticed this problem after getting the turbo done because it was so badly screwed, especially the wastegate bleeding boost thanks to the busted actuator.

Gtr coolers are ridiculously overpriced for what they are imo. Just like every other gtr part. I mean, sure, it's proven that it's OK.

BUT why buy a gtr cooler for 250-400$ which could be a 15 year old POS when you can buy a 2nd hand apexi cooler with the 90degree return bend for like $350 (I've got one).

be careful, some cheap china kits wont fit in skylines.

I had one which had instructions to bend bits of the chassis to fit the piping. err no lol

I also have heard some horror stories like that. Dodgy kits that dont fit except if you cut and bend things are not my best choice. Heard of some guy who had to cut up his fan to make it fit. Not a good idea. Also is it worth getting a forward facing intake plenum or are they a waste of money?

Hopefully I will finally be getting my baby back today. I miss her so much even though she was almost as slow as my laser (I got beaten by a magna sports!! argh). Have to smoke my mate who owns an 88 supercharged mr2. shouldn't be too hard, hehe.

I would keep an eye out for better quality but second had kits, I got a HKS cooler plus piping for $600. Admittedly that was no cheaper than some of the hybrid copies but I was really patting myself on the back when I was able to fit it in around an hour due to the fact that every part was absouluteley mm perfect

    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
    • OK, now we are ready to get started. You need to remove the air boxes on each side for clearance. The cover is straightforward, undo the clips on the top and lift the front cover out of the rest of the housing. If it is tight you can remove the air filters first. The rear section of the airbox is trickier. On each side you need to remove the Air flow meter wiring which is held to the airbox with a clip; you need to get behind the clip on 2 sides if you want to remove it without breaking it - unclip the harder side and pull on the clip with medium force, then unclip the easier side and it should pop out The airbox is held onto the intake hose with a spring clamp; you need to get a flat bladed screwdriver behind the spring on both sides and pop them outwards. When you have got them in the right unclipped place they will stay there and the airbox slips out pretty freely. Put a rag in the intake to prevent anything getting dropped in there, and also to prevent you seeing that the turbo seal is leaking oil (as they do). Then. The top of the radiator is held by a steel plate, it is secured by 2x10mm and 2x12mm headed bolts . Remove them and remove the plate Also grab the bushings that hold the radiator to the plate on each side so they are not lost!
    • Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.
    • Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing
