SEARCHED : q45 TB + z32 MAF = compatible?

[jdm_master_X]

well actually, i have a series of questions.

1. fitment of the q45 TB. i know they will fit on GReddy intake manifolds (possible ARCs as well?). anyway, would it bolt onto a stock SR manifold? reason would lead me to believe that i would need to port match the manifold prior to fitment. ive checked in both recent and archived content, only to find minute details on fitment.

2. how to ID a non-traction control from traction control TB. i saw two TBs at the junkyard, but i pulled off the one with a 3 pin TPS on it instead of the 6 pin TPS. did i get the right TB?

3. z32 MAF compatibility with q45. was this a better combo than the 90mm MAF? from what i've heard, the z32 is good enough to measure 400-500 HP with proper tuning, while the q45 is capable of measuring the same amount of air, but due to its size, is a little inaccurate. concerns?

i just want to make sure i made the right decision in my purchase. otherwise i'm either going to sell it for a little extra, or just end up returning it. anyway, let me know wassup. i appreciate the help im getting.

does GReddy make an adaptor plate or 90mm version for the SR?

[jdm_master_X]

another thing i just thought about -- i know the APEX'i SAFC-IIs and POWER FCs are capable of running a Z32 MAF, but how about HKS F-CON V? I already have that coming along in a few weeks. and how about a FIELD Racing ROM? it came along randomly with one of the front clips i have and i'm tempted to run it, but i dont know what the ECU is set for.

bizump bizao!

bump is on the cheese, bump is on the cheese. if i get lucky, ill get a disease.

BAHHHHHMMMMMMMMMPPPPPPPPPPP

The q45 throttle body is a bit large. To toss it on a greddy intake manifold, you'll need to bore it out. Tomei makes an adapter plate for the GTi-R throttle body to the sr manifolds. Either that or you can have one made too.

Whatcha gonna use for ecu? I don't think Enthalpy supports q45 mafs iirc.

Not sure bout the f-con or the field.

BTW a bump an hour after you make your last post on a slower moving board like this should get you a "nice" response from your local a-hole moderator dude.

[jdm_master_X]

well the ECU i planned on using was an HKS F-CON. its coming in a few weeks. and its not th q45 MAF but a Z32 MAF. the reason i chose the Z32 over Q45 was because due to its size, it might not properly measure the right airflow.

i heard GReddy was making their intake manifolds adaptable to the 90mm TB. i haven't seen one for sale but have seen it mentioned a lot through google search. and im not about to buy th JUN Surge Tank. thats too much.

[180fan]

dunno about the newer castings of the greddy intake manifolds, but I know with mine, it wasn't all that big, well not 90mm big.

greddy intake mani is stock size around 60ish so if u want the tomei tb u need to bore it out and if u want to use the q45 tb then u need to cut off the greddy flange and weld on a custom adapter to fit the 90mm Q45 tb

yah i figured that much with the GReddy Intake Manifold. i might just go that route. definitely bookmarking this link. doesnt recommend usage unless you have a GT28 or higher. hmm..

do you both know the difference between a q45 TB with or without traction control? i know the difference is in the TPS, but which is which? the single 3 pin or dual 3 pin?

[vutony]

not sure, but i wouldnt get the q45 unless u want 600 whp plus, the best route would be to get the na sr20 tb, i think its 70mm so can be easily bored with a dreamel to the mani

[jdm_master_X]

10mm of ID really makes that much difference between HP levels? i would just think the wider opening would give to more throttle response. and i know it would be wise to port match the IM to the TB. same thing goes with the GReddy IM, as to say a turbo larger than a GT28 would be recommended for its application.

[vutony]

i think u should do some more homework before making ur decision

[jdm_master_X]

yeah definitely. thats what im debating on. because im wondering if i should just sell this thing off. i know i want to keep the Z32 MAF but as far as this throttle body im so undecided. there isnt too much coverage on this TB on SRs. its more plug and play for RB25s with the GReddy IM. but as far as wiring and piping, i dont know where to begin, even searching for the diagram or input is impossible. there have been plenty of issues with the TB such as coldpipe angles and throttle pulley adjustments. and nobody has really covered the wiring of it. and as of now, nobody can confirm the difference between TC and non-TC versions of it. ive seen more applications of this TB on an EVO than on an S13.

[vutony]

use the z32 maf, toss the 45

i have the tomei tb w/ the greddy coldpipe (sold seperatly) fits fine

try freshalloy.com more usefull info there

[jdm_master_X]

a lot of people are still split on using the 90mm TB (as am i). there are issues such as rewiring the TPS (which isnt much), bypassing the cold idle lines on the TB, throttle sensitivity (reclocking), and power.

for the record, my plan is around 475-550 WHP to use as a multipurpose car (suspension tuning included, etc.). its going to see way more track time as soon as i get another car, so streetability isn't a major issue for me. i just wanted greater throttle response via TB with a port matched IM (so the flow will be more optimal than stock). and i plan to do all of this when i have the parts ready for it (i.e. TB, IM, fuel rail, injectors, ECU tune, ignition setup, upgraded turbo), but for now, i just want to gather up the parts i would need before i step it up. i just want a more responsive throttle with a larger capacity for air. i already have an HKS F-Con coming in soon, and injectors should be coming up shortly.)

im just so undecided because i got both of these for a great price, complete, and in excellent condition. and to date nobody can give me any sort of comparisson with the N15 TB (Tomei) or the 90mm TB. i sat down with my S13 TB and the Q45 TB and i compared. besides the size and linkages (all the obvious things), the q45 seems to open at 100% true WOT, while the S13 TB just comes short (the Q45 butterfly opens up to 90 degrees, while th S13 TB is just about 80 degrees.) i dont know how much of a difference that makes, but i guess ultimately its prefference.

from your experience, tony, how do you rate the Tomei TB?

[vutony]

i cant give an exact answer to the tomei cuz i just got it and now saving money to tune my car so i wont know the full potenial of it till then but price wise it was dam expensive and my hp goal is only around 350-400 so i had to do it again, then i should have gotten the na sr tb and since u want big numbers and its gonna be a track car, the q45 tb would be a better choice

call hybridynamics ((724)925-2660) since they make the custom flange and have the answers to ur ????????????????

[jdm_master_X]

yeah. im doing way more research into this. i gave in and i might just sell it to my friend who has an RB. maybe ill call hybrid dynamics and ask them about it. did you look at the links i posted?

[vutony]

i kinda skimmed through it but the mani that 02induction makes are ill, similar to the escort that phase2 sells
