Should It Make More Power.

[dead32]

maybe it was 9psi? not 19? jesus somebody knows how to charge.

[N I B]

We have a 25 with as much or more mods that makes only 295rwhp@18psi even with a GT35 turbo ,much less than a stocker will make with the same turbo.Cams were so far out that it only made about 130psi cyl pressures even tho the block was shaved so far that the pistons were touching the head.There is a lot of shops trading in Australia with no idea so be very carefull as this guy payed for a race engine.The 295rwhp was a very small peak at about 6500rpm with less power than a stock rb everywere else and less torque than a basic RB20. Best thing to do is get someone to dial cams in and retune.

[subzeroR33]

lol $40,000k? for only 360rwhp?

HAHAHAHAH your mate has been owned big time..... does he not know how to do anything himself?

If he had 40,000k to spend on an engine he should of bought a twin turbo jza80 supra and spent the money to have an 800hp monster but each to his own i guess....

I have spent like 2k on my car for engine mods and am making in the vicinity of 260rwhp.

I know that to go up i must get a new turbo, computer etc but i would still want to come out f*cking short of 40,000.....

I hope that 40,000 inlcudes bodykits, wheels etc etc....

Yeah well thats what im saying $40,000 for only 360rwhp is a joke.

And no it does not include bodykit, wheels etc.

[subzeroR33]

my rb25det is making 274 rwkws at 17psi and 346rwkws on 24psi and im running gt3040 600hp garrett,spent half the money you have and thought that is alot! post up your dyno sheet, your power curve might give an insight to what is robbing you of power!

This is the best he has got out of it 390 rwhp.

But current tuner only got 360 rwhp.

It should be more for the money spent.

[R31Nismoid]

So where did the 40k go? All on red?

The parts you listed dont even come to 15k mate im afraid to tell you even with assembly of the motor

Unless your mate paid $3000 per rod, and $3000 per piston.

So its either your telling stories, or your mate is

[subzeroR33]

The parts listed are a fair cry from 40k. Doesnt even come close to knocking over 20k

I'd say the figure of 40k was including things like rims, suspension, body kits etc etc etc etc.

But as cubes said (i did not have the time earlier), they are a LOT of things missing.

Even the turbo spec iteself.

All thats been listed is about 1/2, and its not enough detail for the items that are there, let alone whats missing

Maybe the FMIC has pressure drop, maybe the head gasket a whopper and its dropped the comp ratio substancially meaning mroe boost would be required.

Subzero, get your mate to signup and give the FULL detail and history, no-one can really help unless there is basically a thesis on what parts are there, whats been done, whats been tried.

What has not been tried etc etc. Its a lot more detailed that just listing some of the parts that have been used.

Simply saying a car isnt performing and asking for answers is like asking how long is a piece of string.

Ps. im moving this to Forced Induction.

Ok i have the reciepts right in front of me.

total so far $33,975

Going by the reciepts he did it in stages i would say that would cost a shit load in labour and dyno time

going back and forwards.

id neck myself if i spent that much and didn't pull big numbers.

[Cubes]

Damn.. there's a hell of a lot of labour thrown in there.

Anyway... who cares what it costs. Take it some where else, the tuner could simple have nfi.

See, now we are getting somewhere.

Your finally listing all the parts that we've asked! Now expect a longer post qith lost of questions

Now we just need listed whats occured thus far with the tuner...

Have they been asked about it?

What was thier response on it all?

Have they worked with Microtechs in the past?

Are they an expirienced workshop?

What was the reason for not installing cams?

Just while we are here, in "section 2 & 3" that you listed your mate was ripped off something severe. :sorcerer:

More-so section 3 which i'll post here just to put things into perspective for you.

Section 3's total for me came to ~$9,800 not $15,000.

Gt 35 -40 turbo - $1750

custom plenum and throttle body - $1700 (v.rough)

custom fuel rail - $600

injectors - $850

Dump pipe - $250

3"exhaust and 3.5 high flow cat - $1100

custom exhaust manifold - $1500

oil catch can and braided lines - $450

radiator - $600

Labour and dyno time - $1000

Now, if he did pay $15,000 for all of that, it raises an instant question... who he is getting the parts from?

And take the over pricing in section 2 into account (roughtly 3k).

If it was the workshop in question, then i would be instantly changing as that pricing is very very incorrect.

So your mate has, just in parts, forked out well over (in my opinion) well over $8,000 more than he should have.

[rb26s13]

no wonder i do all my own work except for the tuning thats well overpriced

oh yer and the power shouldnt drop off like that specialy with the larger ex housing

Edited February 11, 2007 by rb26s13

[r33_racer]

Going by the dyno sheet. Was it Matt Spry that tuned the car?

If it was another workshop must have done the work as im pretty sure Matt doesnt do any mechanical work...just dyno tuning.

[Ryan1200]

You should note sprys dyno used to read very very low. he has had it calibrated within the las 4-5months but 12moths ago i made 460whp at PITS then went straight (same day) onto a brand new shootout mode dyno and put down 530 in my gtr...

[R31Nismoid]

Its not the figure thats out IMO.

Just look at the power curve, its more painful than a bullet in the foot.

[Ryan1200]

Just stating his dynos not real accurate but yes your quite right its very ugly...

Ok the tuner mainly works with motec and bagged microtech not good but have been going there for years and didnt trust anyone else.

When we got the results of the tune 360rwhp, he said that the map sensor was not up to the high psi that it was running with the microtech.

so he reduced the psi 22 down to 19.

No hasnt had much experience on microtech.

Yes experienced workshop.

Didnt put cams in, ran out of the $$$$$$ as you can see it had already cost a shit load, and they said it was making good power without them???

So whats the problem with the power curve, is that bad the way it drops off.

And thanks for everyones input so far its been a big help.

And just to clear things up.

1) All mechanical work was down in a experienced workshop.

2) The dyno sheet shown above is done at pits with the result of 390rwhp, no mechanical work was done there only the tune.

3) The current tuner has detuned it to 360rwhp and said it was the map sensors in the microtech. He had to reduce the psi as it used to miss and breakdown in high boost.

Yeah that is a big difference which one is accurate.

Well if pits was 390rwhp and the current tuner was 360rwhp his must be really low LOL. So that might be in our favour.

[Beer Baron]

get some cams. after spending $40K on this thing another $1500 or so (cams and installation) would be well worthwhile. then go to somone who really knows the microtech product as it sounds like the current tuner is perhaps a little un willing to work through any problems with the current ecu.

btw, pls come clean! I'm assuming this is your car. just like the time I went to the doctor to talk about my mates case of c0ck rot. lol.

[Gazee]

When i was at Chasers motorworks i was talking to the mechanic there and they were in the middle of building a motor for a r32 gtr, the motor pulled out and put back in including forged pistions and all that normal shit people do, including 2 gt2861's dyno and everything cost around 10k, when they tuned it they got 265awkw on 1 bar.. and probably get more out of it..

This other dude i know that had this s15, under 20k on every mod he done from stock incl clutch and ecu and tune and full rebuild forgies and shit seen him make 300rwkw.. For $40k i'd want a full blown race car lol

[Cubes]

This is the best he has got out of it 390 rwhp.

But current tuner only got 360 rwhp.

It should be more for the money spent.

Whats the 'new' rear housing?

.82? What was the old rear housing? Do you have dyno chart for that also?

[Adriano]

looks like valve springs, put them in with a set of cams, and camwheels.Buy the parts yourselfand pay a workshop $80p.h. to fit it, camwheels are $175 pair in a group buy, stop getting ripped off.
