R34gtt cooler into R33

[Chief]

Hi guys, have heard that the standard r34gtt cooler fits straight in place of the stock r33 cooler. Can anyone confirm this for me?

Also, I have read that the stock r33 cooler is efficient up to 180rwkw, the r34 cooler is supposedly thicker and more efficient, does anyone know how much power its good for?

[ed]

yes bolts straight in.

do a search

Unless you can get the cooler for virtually free then I wouldn't bother, it is an improvement, but it's no FMIC.

Hi gts,

yeh I realise its not going to give the gains that a FMIC will but at 1/10 of the price (approx $150 for 2nd hand) it seems to me to be fairly decent value, unless someone knows otherwise.

how much better than r33 one, does anyone have any figures on it (Ive tried a search couple of times but Ive only found general statements bout efficiency).

hey chief i bolted an R34 cooler into mine, straight swap, no problems.

the thicker core may be a slight disadvantage over wider/thinner cores but when the cooler is ducted correctly it shouldn't be a drama. no increase (discernable) in lag is a big advantage and if you are using it as a road car then most I/C's probably work as heat sinks so the extra 60% ?? vol is an improvement.

Responsiveness may beat kW in many situations.

i have no hard figures on the improvements.

Thanks for the info wolverine! Did you see any improvement in power at all? Im assuming you would probably only see a minor improvement? Im thinking the more efficient cooler may help my car somewhat in the hotter months ahead.

[wolverine]

it was a seat of the pants improvement, so don't rely on this.

till i stick it on a dyno and re-tune it it is hard to quantify, but i think it is a reasonable cheap mod to go for.

i have one on my R33 with the r34 ducting etc to the cooler and the car is also mdded and hasnt pinged or anything strange,

and doesnt seem to care too much

i could notice on my previous R33 when enough was enough and you had to let it cool. so yeah for the small price its worth it, and if you can set up a decent water spray for a few dollars more then thats alot more efficient that stock but yeah still no FMIC

[G0DF4Th3R]

an R33 cooler is worth 100 bucks, approx

an R34 cooler is worth 150 bucks...

sell ure old one and ure out of pocket by 50 bucks for a slightly better cooler

though its no FMIC...but hey 50 bucks

[wolverine]

damn right, they are cheap if you sell the old one, but the best bet is to ensure that you have proper ducting of air onto the cooler by sealing all sides and proper venting into the wheel arch. the wheel arch has a negative pressure (as i understand it) therefore you will get good airflow and velocities thru the cooler (remembering it is a thicker core than the '33) if you take the time to cut and mesh this section.

Agreed, its not a perfect solution for peak HP but for most road applications the responsiveness should leave you ahead. Read rev210's posts if you want some validation from a more authoritative source.

hey I'm no authority!

I'd say the R34 would be a tad better in stockish turbo aplications.

A front mount intercooler carefully selected would be better, just costs alot more.

Hi guys,

Sorry to bring up an old thread, but I though I would just post my feelings on this topic again.

I just bought and installed an R34 gtt intercooler on my car, I would say that based on my initial impressions, I think it was worth it.

Dont get me wrong, Im not seeing masssive differences in power, but I can defiinately feel a significant difference between the new cooler and stock one.

It feels like your upping the boost 0.1bar (or so) more.l As far as actual power differences go I have no idea what sort of improvement I have achieved, but I think that to really notice any difference, you would have to improve power levels by at least 5% so Im assuming were looking at 8-10rwkw.

This is all at 0.7bar mind you, so Im not sure if that makes any difference.

Does anyone have or heard of any real figures on improvements with this sort of upgrade? Would be interested to know.

Hey people, I'm looking at doing this mod if my car doesn't sell quick enough, just to get some extra power

How much boost would the R34 intercooler be able to cope with? Note this would be for short bursts just to dart through traffic etc.

12psi? 10psi? I have a good turbo

12-13psi

Ok and for my next question, does anyone have any Pics of an R34 intercooler?

[yogi000]

dezerteagle......do a search in the for sale section i sold one a couple of months ago with pics and all.

Cheers

[HKS34R]

I will have one for sale in about 2 weeks. Is as new. Asking $135 + postage anywhere in Australia. Dont have pics of it though.

[JAPCAB]

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

[JAPCAB]

what about joining two up

[benl1981]

Hi there. Do you need the R34 pipes etc for this mod? Or if you get the bare cooler is this adequate to add it to an R33 Gtst.

Thanks
