Classic tuning thread on here...
Hi guys,
I remember seeing a while back a really useful & pretty long thread regarding tuning a classic, but can't seem to find it anywhere!
Thought it may have been sticky'd, but it doesn't seem like thats the case. I was hoping to find that as i've used the search & can't find answers to a few questions i have!
Anyone have a link to any good reference points for tuning a pre facelift classics?
Thanks everyone,
James

This gives a good idea of the various "stages", before delving into researching specific products/prices, etc.:-
MY93-96 Tuning Guide
BTW, the Subaru turbocharger scene has come on a bit since that guide was written, so some of those turbos mentioned can be substituted for arguably newer/better designs. Any specific modding questions, just ask...

Ok mate, that looks helpful, thanks
I'm not new to tuning stuff, but new to impreza's! (More used to Skylines, 200's & Evo's!)
Theres just a few things i'm looking at, the turbo will come later as i'm not sure which turbo would be best for my needs at the moment...!
Thanks again mate,

There are a couple ready made ones:-
1) The silver all metal A'PEXi one. But it comes as a full kit with the Power Intake cone filter, etc.
Unless you can find a second hand one for sale by itself...
2) There's aslo MRT's (Aussie company) black metal one.
3) Also, K&N do an induction kit, comprising cone filter and plastic/rubber res. del. pipe.
If you buy the full kits, just fit the res. del. pipe, and NOT the cone filter (sell it on) - i.e. keep the OEM airbox/panel filter (and obviously MAF). Car runs much better with OEM induction (up to c.350bhp).

MRT one is bloody expensive though - around £130 IIRC. Maybe more!!!
Prob. cheaper overall to buy the A'PEXi Power Intake kit (c.£90 IIRC), and get a bit of money back on the sale of the cone filter

you would need phase 1.5.
17 March 2012, 12:24 AM

yes they are called phase 2 and are yellow 440cc,they were fitted to 98-00 cars,you can fit ph2 injectors to your car but it means buying a adapter from carl davey which is £35 i think.
on a v4 sti they will be phase 1.5.

Nice one
I've seen lots of 440's on here & ebay, but wasn't sure if they were correct. I don't suppose the phase 1.5's are a different colour? Would make identifying them a bit easier!
When i get the 440's, and a resonator delete pipe, i think i'll need a fuel lab regulator & i'll be ready to get an ESL & hopefully some extra power!

As 99gw says:-
MY97/98 phase 1.5's = straight swap
M99/00 phase 2's = will fit with <£40 Carl Davey adaptor kit
Re. cone filter - will be fine when you get it remapped, as its different flow characteristics is accounted for for the MAF scaling and the fuelling requirements.

The 1.5s are of a slightly different design to the 2's. The 1.5's have a longer pintle (the nose where the fuel spray out from. Plus the O-rings are different. They're both yellow though.

when joz sells me his injectors you can have my 440s,they are ph 1.5.
i also have a set of ph2 440s if you wanted them but you will need to buy the adaptor.

Well i'd rather get the direct fit ones, there seems to be no advantage in getting ones that need an adaptor to fit
I'll get a wanted thread up for some phase 1.5 injectors.
I'll tell you what i'm looking at with the car,
Full 3' turbo back system
Walbro
TD05 (standard)
Apexi induction/resonator delete
440's
Fuel Lab regulator
ESL & mapping
That should see me to around the 300bhp mark shouldn't it?
ESL & mappin

Apexi hardpipe doesn't fit with standard airbox I saw a really nice one on someones car the other day which was a straight pipe, was unbranded so I assume it was home made. Easily done by someone with basic pipe and weld skills
You don't need 440 injectors really but it's a good idea. Your biggest problem is that poor excuse for an intercooler
As a quick and dirty list...
Decat
Filter
Injectors
Fuel pump
ARC Intercooler
Service with the very best liquids and lubes
Turbo blanket is also a very sound idea given the I/C
ECU remap, ESL or Apexi with boost controller

I would go straght to 550s, as your 16g (assumng a saloon?) is capable of 330-350 (so long as you fit that FMIC) - and it's borderline if the 440s will do the upper figure. At the very least, they'll be near 100% IDC - not ideal

Is it a saloon? Or Wagon STi? If either, it'll have a 16g, yes.
350 is prob the exception, rather than the rule. But they can, and do make that.
But if you 'accept', say, 330, then you can't get dissapointed lol

TD05 won't do a true 350 no I think Bob5 managed 340 with 10% NF IIRC be happy with 320 with maxed IDC 440's, maxed Maf and a 5 speed that won't implode with a month
FMIC is a must for events but this takes away your airbox more power and you need to budget for a six speed and much more besides ...brakes chassis etc

Yeah, i've looked into chassis/brake upgrades, & ideally i'll go for a 6spd.
I'd be happy with 320 in a stripped & caged classic, i think that should go pretty well!!
Is it a good idea to max the injectors though?
Been told a MAF from a phase 2 is worthwhile too?

Silent Running (remembr him?) got 350. So have others, I believe.
But as I said, 350 is the exception, rather than a rule. And I don't mean on 440s; 550s or better (+ FMIC).
And I agree, that if OP accepts the 320-330 bracket, then he shouldn't get 'disappointed'.
