reading this wants me to put a 26 in, just bringing up the old thread. just wondering whats the cost of getting to engine in??

ALOT.

You need to be handy with a Tig welder and air hacksaw as well just to mod the sump. Then youll want to freshen up the motor, need a 25 gearbox, a decent clutch, custom tail shaft, new cooler piping, etc, etc, etc. Also if you cant do it yourself (or have good mates) the labour is going to kill you as well.

As i have mentioned a few times i have kept the rb20 gearbox and im not having any problems as of yet. You will need a much better clutch though. dunno about the custom tailshaft. i kept my gtst one. What also make sit expensive is you start to think "While im at it" then you start doin computer upgrade etc. etc. I put aside $7000 for the conversion but spent closer to $9000

If i had a re-do i would have used an rb25 and spent the extra cash on a better turbo

I went for a 34 gt-t box and hks twin plate. Being a bigger box the shaft had to be shortened. I also went for a pair of 2530s, and a powerfc, as well as afm upgrades, nismo injectors, etc. Total cost has blown well out now but :domokun:

Im making about 310 rwhp at the moment. stock turbos running 11 pound i think. Its gotta go for another tune yet though hopefully get some more out of it.

masters where you talking 300hp or 300kw?

Awesome. Should be a unique ride. Is it gonna be a sleeper or are you doing it up?

what ecu you gonna run?

It will be set up for track work .. Ordered PFC D jetro

Flash89 you can make a comfortable 300 on the stock GTR turbos. Id recomend you just get a RB25 if your on a budget.

DISTURBD you going big single?

No big single , after doing the Dutton with the 25neo 31 we decided we needed that little bit of xtra grunt so building whole new car for next yr

Dont need to do steering rack, im just fussy.

Dude, there is enuf info in this topic to write an essay on the conversion. Read up, get some serious cash together, and get on it.

If its too much, RB25's are cheap, put one of those in.

    • That R31 was so cool. Only did Orange Park once. Scared the hell out of me.

    • The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter
    • Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)
