damn..how do you keep finding these things!! first the BOV, now the oil cooler kit! I would take the cluster, but I'm also a bit turned of by the holes in the dash for them.. I'll probably go with the din panel ones if / when i put gauges in :P

havent you forgotten to list pistons ? you need low compression pistons, otherwise using the standard high compression pistons that NA's have will just F*&k ure engine VERY quickly.. although i h

i have a 1993 r32 gts with a rb20det conversion. i bought it this way so i dunno whats been done. power seems sweet up until 5000rpm, where it seems to hit some flat spots in power from there onwards.

hey i just though i would go back a little bit and add something in, in relation to drilling the oil return line into the block a way of getting around this would be to buy an oil cooler and run the o

I've got another question in regards to the GReddy eManage harnesses. I have the unit with the universal harness that it comes with, and also an optional ignition harness, but will I also need the injector harness? Or will it be sufficient without the injector harness?

sorry to throw this in the thread but.

when would i expect boost to hit with a R32 turbo and basically r32 ecu, etc on a rb25de block?

just contemplating a cheap upgrade on my car. and what boost would be considered safe on it? 8psi?

thanks andy.

Hey Andy, not too sure with an R32 Turbo, but I imagine that it would be smaller and boost even quicker with the high compression, maybe too small? With an RB25DE with R33 turbo, I've read that they start boosting at around 1800RPM, then at 3500 - 4000 variable timing kicks in and it launches.

7PSI seems to be the safe boost level, though some have had good results even at 10PSI with a supposed safe tune.

hope you get your turbo!

im starting to think if its worth buying my 25gt and holding it for a year and then turbo conversion....

maybe i should just buy a 180sx and wait it out till the start of 2010 for a gtt......

not sure what to do because r34s are so attractive!

With restricted P Plate skyline owners coming to their full licence, I think interest in turbocharging N/A's is going to be a bit more common.

dreamaaa, if all you have to wait for is a year, it might be best to hold out till then. You can save a bit more towards a GTT plus mods. That is of course if you don't buy a 180SX and get bitten by the modding bug, and start out with a stereo, then a pod filter, then put a catback, then upgrade headers, etc etc.. though you could buy a 180 and later drop in an RB...now there's a thought lol

In my opinion though, if you were going to buy the R34 GT with plans to turbocharge it later, and you can hold off keeping it pretty much stock standard for that time, then you may be better off selling it to get the R34 GTT afterwards. For those of us though who have already invested a fair bit into our N/A Skylines, it makes sense to do the conversion.

By start 2010 GTT's should drop a bit more in price, and hoepfully for those who want to sell their N/A's, with demand for non-turbo skylines for provisionals, the R34 GT hopefully shouldn't drop too much in value, unless the market gets saturated with them in which case it would just be another non-turbo skyline.

yea i agree!

i just posted a new thread in the turbo section.

was wondering about de turbooing and other mods on a gtt and raising the compression rate to make it drivable....

wondering if anyone has tried this..

It's been thought of before and it's not exactly do-able. If you used a thinner head gasket you'll raise the compression a bit, but for the cost of doing that and de-turboing, getting a factory / aftermarket exhaust manifold etc.. only to return it to the factory turbo set up later, it seems like a lot of time, labour and money. I'm not sure that the stock GTT ECU will be suitable either? Basically it will cost more than it's worth, it still won't drive quite like a non-turbo skyline, and to go back to a turbo means more costs etc.. again.

What you would spend de-turboing a skyline, you might as well buy the n/a skyline now, then save for a turbo conversion and forged pistons later on.

Besides, I think the rule is something along the lines of "an engine that has had its performance modified". Modifying a turbo engine, even if it is decreasing its performance, could still be classified as modifying.

Whilst not necessarily skylines, there's a number of N/A cars out there that are still pretty good performance and P Plate Legal. Even an S13 would be a good Nissan to get around in for a while before buying a Skyline. I had a NX Coupe with an SR20DE as a first car for a couple of months before saving a bit and buying the R34 GT. I had plenty of practice on the company car (XR6 MKII) so I wasn't a stranger to N/A 6 Cylinder sports cars, but looking back I'm happy I started out with less power before stepping straight up to a turbocharged skyline. As some have said in other threads, learn to get the most out of an N/A by improving your driving before buying a turbocharged car.

ahh i didnt think it would be worse than a conversion!

if thats the case i wont bother....shame though.

I was thinking about a 180sx. but r34 is newer and i love the shape etc. Also the thought of having a car for about a year then having to try and sell it is quite annoying. i hate time wasters that test drive it etc. id rather just trade it in( which is probably what i might do. get the gtt with a 2-3 year warranty isnt a bad idea....)

and i aggree with not stepping straight into turbo cars. There are so many P platers that step straight in to a trubo car and its hard to walk away when your cars head is in a tree.

Had a chat to WYTSKY, his hitting over 200rwkw with stock internals. So im guessing i should be fine if i upgrade the turbo and all. :laugh:

Good tune = Good fun :P

i spoke to him about his conversion and he is running around 12+psi as well! gusty fella.

he goes the response & torque is huge!!!!!!!!!!!

yea. would you prefer turbo conversion or engine swap from gtt+ transmission.brakes and later on clutch...

get a GT-V, basically got all the GTT hardware except the turbo motor.
