Hello skyline junkies!

I started a thread a little while back in relation to converting my engine to an RB26. I was pursuaded otherwise, and was told to just forge my internals and get a new turbo.

Currently I am running a HKS 2835 Pro S with all the other mods (PFC, exhaust, front mount, nismo 555cc injectors, boch 040 fuel pump etc etc) and making 273 rwkw, however, it's jsut not cutting it for me.

Now, I need some answers from you good fellas.

1) What do I have to do exactly to get around 350 rwkw? i.e. forge the internals, new plennum, new manifold etc?

2) WHat cost do you estimate ALL of this will amount to, I need specifics i.e turbo $3000, forged pistons $1500, installation et etc??

3) WHat turbo should I be looking at for around 350 rwkw? I've hear the GT35 is the go? But what brand? and what A/R ratio?

Please advise!

I had:

Pistons

GTR Rods

Tidied up head

The rest was factory.

As for the rest, GT35 you'll need, .82 A/R, and just the usual other standard stuff there are 1000 posts about.

How much $$$ ar we talking including install and parts for the pistons, rods, new cooler pipe work etc?

Buy a morris minor......you'll be so stoked that it is going you won't want to modify it. And every time you think about it it will break down on you and rob you of the chance anyway!!!

Otherwise, go the Gts30t.

i spent $23k on mine

just purchased a new car for the family so my engine is up for sale.

$12k if your interested.

350rwkws.

all included.

Yeah but your's is auto. I am after a manual.

What sort of turbo you got on yours, it was a GT3540 wasn't it?

See the thing is, my car is not stock, I already got the foundation; Power FC, Nismo 555 injectors, bosch 040 fuel pump, 3.5" exhaust, front mount, splitfire coil packs, Jim berry 'full monty' clutch. Plus, I should be able to sell my turbo (GT2835 pro S) for around $2800.

So if you spend $23K on yours from stock to what it is now, if I do it, it should be something less yeah?

Probably not a lot less.

Your only saving what, 5k or there abouts (injectors 800, PFC 1400, pump 200). I dont include anything else as coil packs aren't always required... and exhaust because everyone has one.

Although not sure about 2.8k for a 2nd hand HKS turbo, i could be wrong

    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
