Dumb Question Thread!

I have the second one, its held 20 PSI for about 2 years now no issues.

But the second one is a non branded, surprisingly cheap bov.

this should bolt straight on right. Did you buy yours from trade-me or a performance store? Let me know, cheers.

My v7 wagon knocked like f**k on 98 with a bit of heat soak.

Also had a hks ssqv on the 7, didnt have issues with it stalling / stumbling idle because of the design of them. Gfb are good, but imho a bov is no good unless you go for a speed density tune, because that calculates manifold pressure instead of measuring airflow. But they a bastard to set up.

If running dov, you also loose response

fair enough but the SSQV's are around $395 .. don't want to spend that much on a simple bov. Cheers.

so you reckon, don't get a BOV?..

Would a td06 20g be to laggy on on a standard v3/4 setup?

I reckon keep recirc valve, but do the snorkel delete and drop a ram pipe down behind your spotlight cover (i've got an old set of covers if you want to drill a hole, pm me) and it'll give you an audible but not obnoxiously loud sound, plus keep the car running nice

What he said.

It will be awesome if its a good turbo not ching and you throw a link and tune at it. You will be limited by your block and injectors after that so would have to run low boost which makes it a bit soggy.

Will it make any difference if it's sti?

Nope shortblock/injectors will only make 220-230 safely and you need a tuneable ecu to get there anyway. V7 sti or forged shortie, link and injectors and its worth running.

Is that because shortblock is open deck?

I was under impression v3/4 sti had factory forged pistons and rods? Hf3 pistons

Yep they are forged pistons but rods seem to let go around that kw. Blocks not built for massive power either. Engines only as reliable as the tune.

Throttle body spacers? Does anyone know if they are worth it? do they help in any way. I have been reading up on a few sites, most say they don't really do much. But I am thinking of getting one made (looking at 3D printing). Do I bother?

manifold spacers yes. Throttle body I really don't see any point

I will be adding the manifold spacers at a later stage. Most of the throttle body spacers look quite narrow (12mm or so), I was wondering if I increased this to maybe 30/50mm would this make a difference. It seems that you may get an increase/shift of torque with the spacer, so a longer one should help? as I said I may make one up and see what happens.

Sell your car and buy a gtb seriously. You spend millions on dumb mods like this or just buy a gtb and have double the power for zero cost. If youve upgraded cars already disregard.

can you convert a Auto BG5 dash cluster to manual? only asking as i know of an STI 240km one and really want it except its auto and i need manual.... could i pull covers and swap them with a manual one ?

Am i cursed?

what's 1 + 1?

Does my 98 bh5 gtb have an open ecu?
