Hi guys i am buying my first skyline on monday, a 96 SII 33 GTS-T. I have been looking for guides on what to do to safely build a 220ish kw ride. i found this guide on how to do it but im unsure if its worth following and how much each thing costs... could people give me a bit of feedback on its method? also, can anyone give a ballpark figure of what each stage would cost? inc labour. Original guide here http://nissanskyline.6te.net/tuning_GTS25T2.htm Engine Tuning Stage 1 Exhaust (around 160rwkw) The RB25DET is a sweet sounding engine but very quiet in standard form and as with most factory turbo cars the exhaust causes a huge restriction. A good free flowing exhaust will have the RB sounding great, turbo lag will be reduced, and power gained throughout the rev range. The new exhaust should start from the turbo with a dump pipe either a 3" open bell mouth or better still a split dump to separate the gases from the turbine and wastegate. From here a high quality 3" high flow cat should be used, then 3" all the way to the back of the car with high flow mufflers. Average Cost: ??? Intake (160 to 170rwkw) Now we have the exhaust side of the engine breathing the next step is to get more air into the engine. Either use a high performance air filter, or replace the air box with a POD style air filter. If you choose to go the POD filter route I recommend you fabricate some type of shield to keep hot air from the engine bay away from your intake. A cold air intake to the filter from the front of your Skyline will also give you a performance advantage. 5-10 rwkw is achievable with this mod. Average Cost: ??? Intercooler Upgrade (165 to 180rwkw) The standard R33 intercooler is tiny and before a boost increase I recommend installing a better cooler if you don’t you risk detonation on warm days. The R34 GTT intercooler is a good cheap upgrade for the R33 and bolts onto the same position as the stock item with minimal modification. The GTT intercooler is rated up to about 200rwkw if you plan on going further than this power figure a GTR or aftermarket front mount will be required. Be aware that with these systems new pipe work will be required and you may notice a small decrease in throttle response. You may notice a small increase in power with this mod without increasing boost as airflow will increase and the air will be denser. But it’s the ability to run more boost that makes this mod a good one. If you don’t plan on increasing your power level to over 200rwkw I recommend the GTT intercooler as its cheep and you will notice no difference in throttle response. Average Cost: ??? Boost increase (175 to 185rwkw) In standard form the R33 runs a two stage boost control system 5psi to 4500 rpm then 7psi to red line 7000 rpm. As mentioned before the turbo’s exhaust wheel is ceramic and they tend to fail if to much heat is generated. The amount of boost you can run with the stock turbo is debatable but I don’t recommend running more than 10 psi. You have a few options when choosing to increase the boost either a manual boost controller, electronic boost controller, or a new wastegate actuator. A manual controller is very basic in its operation it bleeds off air causing the wastegate actuator to open later. The amount of boost run depends on the amount of air bled form the system. It is critical to install an after market boost gauge before carrying out this modification as the stock gauge is not accurate enough and is measured in mmg not psi or bar. Manual boost controllers are cheep and easy to install but they do have there disadvantages some can cause boost spikes and boost creep I have also found boost tends to tail off high in the rev range. Electronic boost controllers on the other hand use stepper motors and monitor boost about every 10th of a second because of this boost spikes and boost creep are kept to a minimum, and the desired boost level is held to redline. Electronic boost controllers are expensive and for this level of modification a manual controller will probably be good enough. A 3rd option is to install a different wastgate actuator and the good news is the R32 GTST item is exactly the same as the R33 except the spring inside is set for 10psi. R32 actuators can be hard to find but I think it’s the best option for this level of modification as boost spikes and boost creep are eliminated. No mater which system you choose the 2 stage boost control system should be disconnected. After this mod is carried out many people notice flat spots throughout the rev range this is due to the ECU seeing an increase in airflow and as a safety precaution it richens the air fuel mixtures. Many people find re-gaping the spark plugs from 1.1mm to 0.8mm fixes this problem but if it does not you need to consider the next upgrade. Average Cost: ??? Iv been scouring the web to try and find something similar to this and i cant seem to!! i know that each person has their own different way of building their car, but for some1 such as myself with little mechanical background its hard to know what will give returns without spending big money on things that i dont need. basicly i dont want parts which will support over 300rwkw+++ i just want parts to run a safe 200rwkw without blowing my budget. Hopefully i see some of you guys around in my new ride Jimmee

thats a damn sharp 34, drives nice too

it would be nice if the pictures were larger, especially the interior pic

would u get it tuned before inspection? i have cash and im ready to buy, but i wont buy anything with promises like "yeah that problem will be fixed with a tune just havent had time/lazy' i want to see it running smooth first time or i keep looking lol hell put the tune on the price if i like it ill buy it

havent bought one yet, after seeing a few power focused builds iv decided to look for around the 200kw mark for a 33. had some pretty nasty surprises whilst looking haha

hey guys still looking, checking some out this weekend will post here if i buy

thanks for the info, its a great looking car man with a nice interior ill be keeping my eye on it

Looking for a tidy 33 or 34, Manual around 100 *** km im buying for power but ill check out any can inspect asap. was looking to buy gregs Dou33 but sold before i got there ^^ anyone and everyone who is thinking of selling let me know so i can check it out iv been looking through the threads but as you probably know they get pretty old pretty quickly and most done have a sale confirmation post.

what sort of power are you getting?

hey mate what sort of power are you getting?

im looking for a 33/34 but id like to see some pics

theres no pics!

Very interested mate, it would be pampered in my hands

have u ever had it on a dyno?

awesome ride man over the last few months iv made the tough decision to look for a manual though, nothings final though so you might here from me later! iv looked pretty thoroughly at ur car earlier so ill remember it

Hey guys, im just about to buy my first skyline, looking at an r34 Gt-t. Im going nuts over the prospect of it in a few weeks and before i rush out and buy the 5th i look at, has anyone got any tips from experience to convey? i have a decent understanding of parts ect i just hold your opinions highly! Cheers in advance
