R34gtt cooler into R33

[wolverine]

bolts straight in ben. nothing else is needed.

[R31Nismoid]

has anyone ever frout mounted the stock cooler b4??? lol

youd hope no-one wasted thier time.

no point running 12-13psi. The stock turbo makes little to no extra power over 10psi, at a cost of the turbos life.

[MANWHORE]

I seriously reckon it's a waste of time. I'm running an r34 gtt cooler in my car. the work to change them, as well as the cost, is just not worth it.

You get a small improvement, for a bigger time and money cost than it's worth. Save up and buy a front mount.

[benl1981]

Really - thanks for the tip. Might forget it then! I was possibly going to up the boost to 10psi and I thought this might be a safer way. I dont want a front mount though.

Anybody know what the pressure drop across the 2 coolers is or intake temps...to compare

[wolverine]

it took me less than 30mins to install the R34 cooler, i squeaked it in without removing the front bar so if you need to remove the bar then this will add to the time and hassle. i just stuck it up on a set of ramps.

certainly given the price of FMIC's the cost advantage has narrowed (but cost of pipework remains an issue) if you are looking for a cheap DIY mod then this is ok, at the right price.

with a standard turbo that doesn't love being pushed much beyond 12psi, spending $800 on a FMIC and pipework (+ labour to install??) vs R34 IC and running between 10-12psi for possibly $150ish you will be slightly behind on longer applications of wide open throttle (WOT), around town i bet it makes stuff all difference which IC. arguably the response it better with the smaller IC.

at higher boost the pressure drop across the nissan IC's is significant.

i measured inlet temps at the plenum and they remained controlled for street driving, not as good as a FMIC but ok.

if you are going to upgrade the turbo then don't muck around buy a FMIC, if you are going to keep the factory one this modification is a reasonable option.

wats the pressure drop liike over the R34 cooler compared to the R33 cooler? Anyone checked this?

thanks

I bought Georges cooler off him (thanks mate) and my car went from 156kw atw to 165 with no other changes. Then we put the boost up to 10psi and got 190atw so I am of the opinion that it is a great mod for the price. I will say that my stock cooler was a bit damaged so that may have something to do with the difference. As wolverine said, for 30 minutes work and 150 bucks I cant think of much better.

[benl1981]

Wow! that sounds good. Do you have a SAFC to get 190rwkw or did you just turn the boost up? I guess you have full 3" exhaust..

Pretty impressive!

[wolverine]

sdm33, i think that is my old IC that i sold to george. good to hear you got a solid result from the cooler.

[benl1981]

Do you guys run the guard in front and the wheel arch plastic bit behind the cooler? My car came with none. I dont really care at the moment becasue it is the standard cooler. But with the R34 my carefactor might be up slightly.

[wolverine]

i cut out the plastic wheelarch guard and riveted stainless mesh in its place.

if you have the factory plastic scoop on your existing cooler bolt it on the R34 IC this will ensure that all the air goes thru the cooler. i had to fabricate one out of sheet aluminium on mine to keep the efficiency up.

[benl1981]

I thought this cooler is a bit taller..will the existng plastic scoop be ok? What about the wheel arch do you think rocks could get thown up if I don't put it in

[wolverine]

if the scoop doesn't fit then modify it or spend an hour or two making something with 0.6mm aluminium. (aluminium shops occasionally let you scab an offcut or two).

i have never heard of anyone having a rock thrown up......but why not mesh it?? takes no time to do and solves the problem.

[benl1981]

oh ok - thanks. Did you do the mesh in case something got thrown up??

I'll have to have a look and see what could be made...

R33 stock cooler VS R34 stock

sdm33, i think that is my old IC that i sold to george.  good to hear you got a solid result from the cooler.

It sure was, i never got to use it. wolverine's setup was really professional on his r33, it looked like it was extremely efficient. also a top bloke.

[mickr33]

Does anyone have a R34 cooler they want to sell cheap.....................

[mickr33]

Obviously not. Ok then any suggestions where i could obtain one from as i have tried many wreckers with no success.......................

Hi guys, based on my experience, r34 cooler fits fine with plastic guard although its a bit tight (the plastic guard makes contact on the bottom of the cooler). I found that the guard wont sit exactly flush with the guard; the guard will bend out o little bit, but if you use the plastic button things to fasten it on, it will be fine.

I bought Georges cooler off him (thanks mate) and my car went from 156kw atw to 165 with no other changes. Then we put the boost up to 10psi and got 190atw so I am of the opinion that it is a great mod for the price. I will say that my stock cooler was a bit damaged so that may have something to do with the difference. As wolverine said, for 30 minutes work and 150 bucks I cant think of much better.

Thanks for that sdm33, good to know, thats what it feels like on mine too. Terrific little mod this one..

[MANWHORE]

Fellars, i'm sorry, but I have to disagree. Doing a dyno, I got an extra 4 kw. but that could be anything - better fuel, cooler day, different dyno etc. the increase in size is negligible. Compare this to fmic where people gain 20 kw - now that's obvious where the gain is from.

think about the cost - new fmic available for 220 in for sale section. piping from diy section using silicon fixtures - 250. that makes a fmic installed for 470. why would you spend 100-150 for an r34 gtt cooler?

even if you sell your stocko one, they go for like $50. Hardly worth the trouble.

to do it properly, you have to take the front bar off. I could slip the cooler in, but not the air duct. had to take the bar off.
