Can Anyone Offer Some Advice?

[DaFuca]

Now for some of you this may seem like a pretty easy question, but I would honestly like to know..

If I was serious about the performance of my R33 GTS25t, then would I stick with my RB25DET, or would it be better to step up to a DETT with a R34 NEO head?

If so what advantages will I see behind doing this?

Will it increase power? or what will it do?

[thrtytwo]

im no expert and have never done an engine rebuild let alone an engine conversion, but wouldnt it be cheaper to source an RB26DETT ?

[BOVed]

I havn't been into this long myself im no expert but Ive asked some questions kinda the same so here goes:-

mostly depends on your budget and what kind of power your want to end up with, see with a GTST unlike GTR your rear wheel drive and when you start heading over 300kw at the rear wheels your gonna start having traction issues and problems keeping the car on the road and you'll go through alot of tyres unless you upgrade suspension and chuck on some real wide tyres like 9/9.5/10 inch wide wheels,anyway besides that theres a few engine options here-

Go with a few light mods like front mount intercooler,aftermarket ECU like Apexi Power FC,Aftermarket Injectors,High flow your stock turbo,boost controller,3 inch split front dump pipe and high flow cat and 3 inch cat back exhaust-ive probably forgot something important but this should/could get you to maybe 220-250kw? and your probably looking at for this after paying the labour and tuning about $4500-$5000

or you want more power-

Get your Rb25DET rebuilt with heavy duty internals on top of most of what was said above and add a larger aftermarket turbo like a HKS30-- and aftermarket cams etc wider exhaust like 3.5 inch and should/could get you to 300/350kw and cost about$10000-up plus the cost of wider wheels and suspension bigger brakes etc...

or more power?!

You could drop in an Rb26DEtt from a GTR and do all the equivelent to that theres even kits to stroke them to 2.8 litre and put on two bigger aftermarket turbos or replace the two with one HUGE arse turbo but to drop a rb26dett in a gtst you need a new loom and sump plus conversion plate to change from all wheel to rear wheel drive and Im not even going to hazard a guess at what that'd cost

But what most GTST guys who are serious about getting the most outa these cars and even some GTR owners are doing are building or getting built for them hybrid engines-RB25DET/RB30DET or RB26DETT/RB30DET thats the head off a skyline and the bottom end from a VL calais or older skyline bolted together with heavy duty internals and big turbos and from what Im told these 3 litre engines are getting unbeleivable kilowat and torque but one of these engines will end up costing about $20000, theres a guy on here selling one rated at 1200hp plus nitrous kit etc... for $12000 if your interested

anyway I hope Ive helped and not just confused you further, like I said Im no expert so dont take me word for word Im just going on what Ive learnt from this forum -good luck

[cepatsikit]

its all about budget

[DaFuca]

Finally some information that I can use.. yes that is what i was after, and no it didnt confuse me...

So your saying that with my budget, I should stick with a RB25DET and just do the basic bolt on's.. Turbo, intercooler, and ECU, Exhaust.. and that should bring me close to me target of 250rwKw..

Labour doesnt mean much to me, cos i can do it all my self, but the Tuning i need someone to look at, so if anyone is in Adelaide and knows of someone in the field of Turbo Tuning that is any good. let me know.

PS where is the best place to get Skyline Mods from? is there anywhere in Adelaide? or worth branching out to NSW or Vic?

[evil_weevil]

Have a look in the SA section of the forums - plenty of answers there.

Or use the search function

But in regards to your first post, 25DETT - no point!

by thetime you t/t your 25 - may was well have bought a 26DETT and put it in

Im in melbourne so I can't help with shop front retailers and workshops but I but most of my new parts through buisness traders on this forum or Ive found www.nengun.com (theres usually a link at the top of the forum) to be the cheapest and theyve got a huge range, If your going to get your stock turbo high flowed, thats having the internals replaced with garret parts and bringing it up to a 400hp turbo and keeping about the same spool time then rip it off and send it to CGC in NSW theyll do it for under 2g and usaually takes em bout 2-3days

[BOVed]

PS:-you can push an unopened engine over 250kw even over 300kw but most recomend keeping below 270kw if you dont want to blow something internal

In adelaide I recommend high tech dyno, run by John Keen really knows his imported turbo cars.

Ive been to morpower and boostinoz in the north and would't recommend them.

Well what is the budget?

i dont see it in the thread yet

[DaFuca]

at this point i am unsure of my budget, i am still searching for a R33 GTS25t. My mate is heading over to Jap in a couple of weeks and i will know then how much i will have to spend. But i am hoping to get an R33 GTS25t to around 250 kw's for upto $25,000

[2BNVS]

buy the motor some guy is sellin like mentioned, just get a big turbo and fuel system and ecu

ben...

25,000 though for 250rwkw...

hardly

you need a max of around 10k depending on what you have already etc

So your saying I need about 10,000 to be able to achieve 250 rwKw?

Cos that is do able. Just needed to know a rough idea. Still not sure what way i wanna go,

Anyone know the advantages behind RB30 bottom end and a RB25DET head? and no one has told me if a NEO head is worth the trouble?

Including the cost of the vehicle perhaps?

[DaFuca]

Yeah that is what I thought too, but i still have very little idea of the cost of line parts and mods.

But I think enough people have told me that it is possible to do with that kinda money, but how much does a low k'd series 2 or 3 R33 cost? looking for a rough price. R33 GTS-25t Series 2 or 3 pref under 80,000k

If your gonna go rb30 better of with the rb26 head, havn't heard of any advantages with a neo head I dont think theres alot of difference-as for more rb30 info theres a f***in HUGE thread just go the search button and put in rb30 conversion and read read read!

local or import? mods or stock? black, white, burgundy or silver? lol! just kidding

www.allblitz.com.au I think thats it? check them out and Im sure theres more than a few importers on this forum

but take my advice take your time man, I just WANTED!!!! a line bad and rushed into it and bought like the second one I looked at and had a few problems allready had the car just over 7 months!

if I could go back I think Id probably try and find one that looked good with a f***ed engine and buy the rb26/30 thats being sold and dump that in, instant beast!

Yeah I am trying to get as uch info as i can on what i want now, cos i will be finished my other car just before x mas, so i will be looking around then. but till then, i will prolly drive you all mad with stuid questions, till i know all the ins and outs of what i want.

if I could go back I think Id probably try and find one that looked good with a f***ed engine and buy the rb26/30 thats being sold and dump that in, instant beast!

Yep I am thinking the same too.

If you are after 250rwkw keep the rb25 and install a gcg highflow, HKS 2535, HKS GTRS or similar. You will need supporting mods though.
