I'm currently using a R34 smic. My tuner told me to upgrade to a front mount after the last tune. His exact words, "if this was my car, i wouldnt be using that intercooler"...."do it, its worth it"

I fitted the r34 smic a while ago, as an easy upgrade, and it made a nice difference. Thats when the car was making 185kw.

Last tune - 211rwkw on 11-12psi. Only mods are, full exhaust, pod, and unichip with boost module.

What are your experiences with fmic on stock r33 turbo?

Glad you did it? Regret it? Wasnt necessary?

EDIT:

I fitted the front mount and took it for a drive tonight. It's raining though, so nothing crazy. All seems good. I didnt notice any extra lag. It does make more noises now lol. And it seems to pull well, so no complaints there.

Just wondering if a tune is recommended after the install. My tuner told me i'd definately need one. I know it was a huge benefit after exhaust mods. So i'm pretty much planning on getting it tuned.

What are your experiences?

I have a FMIC on mine (stock turbo, POD, catback, ~8psi) and I noticed a mild but not insignificant increase in power since fitting it.

Id recommend it, the just jap kits are quite cheap too.

I used a blitz lm cooler, same side inlet outlet fitted well on the S2 GTST. Lots of trimming and cutting of intrusion bar and bumper bar was needed to make it fit well. As for performance did notice a bit of a power gain with stock gear boosted 12psi and 3" trust PE II turbo back exhaust with split dump pipe. Sounds great and does seem have more power. JUST DO IT!!!!! :closedeyes:

thanks for the replies. so far, you've confirmed what i was thinking :closedeyes:

With the money you spent on a uni-chip how come u didnt just get the apexi pfc or an ems system

the unichip was in the car when i got it. i thought about replacing it, but i found a tuner who knows these units well. he used to tune them for race teams when they were popular. i'm happy with the results. they are actually quite good if you get someone who knows what theyre doing.

Well anything over 200rwkw is a bit ambitious for the stock turbo in terms of results.

No-one ever backs them up with a decent mph on the 1/4 really. Most just bring home the usual 105/107 or so.

I really think the R34 factory side-mount will be enough.

There was someone who did a write up about a year ago to do with ducting it or something.

Cant remember exactly but there was a little bit extra in terms of keeping the cooler 'cool'. Got a few degree's which wasnt too bad

the r34 smic can handle at about 230kw atw.

If you are keen on holding onto the smic, look into water-spray kit for the smic.

by lowering the temps of the smic, this should allow you to gain more power.

Although, dont get caught with no water and a higher tune hehe

Thinking of installing the water-kit to my r34 smic on my r32.

Ive got the r34 ducting, and my front bar has an opening directly to the ducting, so it's as good as it gets in that respect.

the r34 smic can handle at about 230kw atw.

If you are keen on holding onto the smic, look into water-spray kit for the smic.

i wouldnt bother going to that trouble. if it came down to that, i'd just go with the fmic.

what symptons would you see if the cooler wasnt up to the job?

these are the main reasons i'm considering the front mount:

- as far as i know, cooler intake temps make for a healthier/happier motor.

- consistency is another concern. sometimes it runs great, and other times it's a bit less great :D

- also, if the cooler is creating restriction, the turbo will be working harder to make the desired boost.

these are the reasons i wanted to avoid it:

- added lag? (not so sure about this one)

- wank factor (dress-ups rather than performance requirement)

- defect

i'll be going with a tube and fin for least restriction, with hopefully improved cooling.

lag is not that significant. So that isn't a big problem.

Maybe it's time to get an airbox for your pod filter :D

actually thats another bonus. fmic means i can set up a cold air feed to the pod through the unused hole for the factory cold pipe.

and at that stage, i'll partition the pod.

If at stock boost you will not gain top end with a FMIC over a R34 SMIC. Maybe over a R33 cooler you may gain like 5rwkw. You probably notice it more because there is a slight delay in the throttle response then you feel the power.

Such a waste going FMIC if on the stock turbo..plus you usually have to hack into your car a bit.

Mate you get no power from a FMIC or R34...

the power gain is from the increase of boost

I think it makes sense that you DO get more power as the larger cooler is able to reduce intake temps at the 'same' boost level. Hence explaining rekins results and ones of my own.

+ me for the r34smic as i have 1 on my r32 aswell.I purely got it for the fact that it will let the air flow alot better

and because its slightly larger i guess thats beneficial in cooling.

i dont have a dyno sheet showing back to back smic install but i have 165rwkw.

With the stock turbo, the r34 smic is best option. 211rwkW is pretty decent for the mods you have and fmic will just add lag, wait until you do the turbo.

Take note of what Rekin has said and posted, he's the only one with supporting results.

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Mistakes were made, my R34 Story

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
