I have an R34 GTT, current modifications i have on my car are intercooler, exhaust, Bosh 040 fuel pump, pod filter (boxed) & Boost controller.

I'm booked in for a tune on friday, i was hoping to get about 250rwkw from my car.

Any recommendations on what other mods i need to achieve my goal.

Thanks in advance.

A bigger turbo and an ecu

Should've got all the parts before the tune. Generally you need:

550cc injectors

Z32 AFM

Boost controller

3inch metal inake pipe with good pod filter

3inch exhaust with Honey con cat

High flowed turbo

Strong clutch

fule pump

Nistune or better ECU

Feed it with BP ulitmate.

the "tune" you have done on friday is going to consist of the workshop driving the car onto the dyno, doing a run or 2, possibly playing around with the boost level, doing another dyno run and then driving it off again. the stock ecu can't be tuned.

and as has been said above, you are going to fall short of your goal of 250kw by about 50kw.

...or more. With a standard ECU you'll probably hit rich and retard (as i did) eventually which makes the car a pig. I managed 185rwkw with exhaust, pod and 13psi.

With an aftermarket ECU and Z32 afm (or a better ECU with 3bar map sensor ie Haltech) you might be able to make 210+ on the standard turbo, although don't expect it to last all that long at that power level...

You'll need a credit card...............with approx. a $5000 limit.

Then you can buy all the necessary hardware!!!

At least...! I just dropped $12k on my R34 to make 273kw, although that was with an expensive ECU and other parts and it has plenty more left in it for E85...

I reckon you would pull around 200rwkw ... you need the turbo +and both aftermarket ECU and Injectors

I'm voting 180-190(ish) tops.

Fuel pump and intercooler will make exactly zero difference to power and as i mentioned my 34 made 185rwkw with some boost, pod and exhaust.

Of course Dynos do all read different - 200 on one is 180 on another...

not quiet true. fuel pump won't do squat for power, but as you start doing other mods then you need a better fuel pump to be able to flow enough fuel to stop it from leaning out.

as for the intercooler, they can make you get higher power than the stock one. the reason being that if you give the car a bit of a fang on the way to the dyno then the stock side mount cooler will already be suffering from heatsoak (therefor higher intake temps and less power) before it even goes on the dyno. a bigger intercooler will stay cooler for longer and therefor give you higher power on the dyno (as well as on the road). it doesn't take long for the stock cooler to heat up after you have given it a boot a few times, while in the colder days we are having at the moment a fmic will stay cool for much much longer.

The fuel pump will only help once you reach the limit of the standard system (as you say) which won't be happening here.

The cooler - well it may help in the situation you described, true - but usually i'd assume the car would be sitting around, run a couple power runs and that's it, with a fan blowing into the engine bay. This is not a proper 'tune'. It can stop power loss through heatsoak / high inlet temps yes, but it's not going to give you more power per se.

Essentially what I meant was your not going to get an extra XXkw with those two mods... :D

and i pretty much agree

      R33 general questions

      By Kaptain · Posted

      Im not entirely sure exactly what or where its leaking from, he started to pull the boots to swap to my new tie rods + ends and it just vomited fluid, so he closed em up up, swapped the rod ends to the old rods and let me know so I can figure a solution out, im guessing its all origional as as I passed 103k miles earlier this year im sure its just in need of a full overhual/rebuild anyways.    If i could just yank it off and be good it wouldn't be an issue to ship it out and wait for the turnaround but the guy I work with doesnt really have space to keep my car for a week or two at a time, would rather drop it off and have a replacement ready to drop in

      R33 general questions

      By GTSBoy · Posted

      What do you mean by "seals"? Internal hydraulic seals (ie, is it leaking PS fluid?) or the rack boots that close the rack onto the tie-rods? Because the former is a rebuild, and the latter is trivial that you or any nearby mechanic could do. Dunno about the cowl. Just buy what you think is required and get anything else you find/break afterwards. Wing? Dunno. Don't like R33s enough to pay attention to them. Mirror glass is just glass (on the surface that you want to polish). Go for it.

      R33 general questions

      By Kaptain · Posted

      Hello! Long time lurker, been using the forums to address concerns and questions from afar for a while but I've struggled to find some answers so I guess its about time I made an account and formally asked some more knowledgeable people, since finding local skyline owners is hard (and shops that are knowledgeable or trustworthy to work on 'rare' cars are non existent out where im at, as skylines are quite uncommon to find in the wild around here). So the main 3 questions I have, 1: Steering rack has blown seals, well.. they kind of hold but they are not sealed properly anymore and as my R33 is my DD, i cant exactly rip the rack out and send it off or attempt to fix myself. As most refurb ones are around $1,100 or more shipped, and I have other things I need to work on around the car, I was seeking clarification on whether an S15 rack will more or less bolt right in, and whether a common mechanic could do any other required work to get it to fit. I ask, as I've found a supplier than can sell a manufactured as oem one for around 400, if not I'll likely order a used one from Jacks JDM, and take a risk on the seals there. The second question i have is that im replacing the front wiper cowl and have planned to buy 4 new clips and a new center clip but wasnt sure if there were any other clips that would also need to get replaced while I was at it. Given im sure any that are there now will simply break when I remove the old cowl... Last thing would be a fairly straight forward question, i think. If I manage (strong if, finding one has proven to be a pain) to find a R33 GTR spoiler/wing will it require much modification to bolt to a S2 R33 GTST? I've read the bolt patterns dont match but otherwise would bolt in, only options I have found with much luck is China stuff on ebay and carbonetics, which has a nice $650 shipping fee... so if anyone has any pointers where a US chap could locate one that would be great Random side question as well, the mirrors as I understand are mirror glass, and as im planning to polish my windows from water spots and surface scratches, i was hopeful cerium oxide would be fine for them too, as my research points to, but clarification is always nice. Any pointers would be appreciated, and while I have scoured the internet for answers if I missed a prior post somewhere that may answer these directly please point me towards it, as i must have simply missed it. I have seen a post here or there that has mentioned it, but I usually get 50-50 answers, or half answers... I dont have a lot of fab experience or mechanic experience, outside of hydraulic and pneumatic stuff I did in the military and with how hard it is to source stuff in the US, id rather not wing it and hemmoraghe money lol. Thanks guys! Sorry for the monumental first post haha

      Did tie rods. Steering now not "springing" back.

      By AdiR34 · Posted

      Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!
