What should be my first engine mod on my classic? and how much am i looking at for it?
Cheers

 

Depends on where you wan to go. There are some cheap mods to do, by changing fueling to paralell, FPR added, fuel pump, some hoses changed, new air filter, panel or cone, or blings bits, the lists goes on and on.

Think about a goal, ie bhp or just a good looking engine bay.

 

I went for a good panel filter, let the beast breath easy

 

hi sorry ment for bhp i have got the blingy bits and waiting on a set of red hoses, Got a kn and polished strut brace, adjustable dampers and ride hight ( Gab ).

 

Proper service completed by a specialist..decent plugs,oil and a panel filter.

 

To be fair there isn't one mod that you will notice a great deal of difference from, the power comes from a combination of mods and a remap.

Modding the car isn't particularly safe without mapping the car to suit, Cone filter not a good idea unless going for huge power...... or a FMIC, it's not needed!

Buy the bits, store them up and fit them all in one go and get it mapped, it's great when that happens, from slow to FAAAST in one sitting

 

The single most bolt-on mod to release as much power as poss is to put on a decat downpipe and a remap. This typically liberates upto c.40bhp safely (dependent on your MY/injectors/turbo...).

However, you really should team this with a Walbro 255lph fuel pump though - and also a good idea to replace the panel filter/plugs/fuel filter with fresh items - before the remap. Also a full aftermarket exhaust system complements the decat too.

As you can see, as mentioned above, it's economically viable (in the long run) to fit all of that (rather than just the decat only) before the remap.

 

Model/year would be a good start as these cars vary in power/ecu's and things that can be done with them.

Check the coil packs

 

It’s important to service, or replaces the oil pumps on the early cars, it's worrying the amount we see with loose backing plates, this is especially the case when service history is staggered.

In my opinion I would do this first or install an oil pressure gauge, check the engines general health then tune from there on in.

 

Agree with above about getting a good service done, mine needed plugs and coilpacks when i bought it.

Made a nice difference to performance aswell.

 

Got a guide to checking the oil pump?

 

All sound advice and taken on board cheers. Gonna look for a oil pressure gauge on ebay for starters and then have a full service at the clinic. It had one 4 months ago and new cam belt. Its only done 69000 and is boosting at 0.5 so its safe at the mo.

 

Isn't 0.5 bar safe mode?

A error code caused mine to run 0.5..... i thought they ran 0.9 as standard?

Maybe I'm talking about imports here, are you a UK or import?

Or i could just be totally wrong haa?

 

just standard boost i believe. I am a import. It runs sweet so hope this is just standard boost ! Just been and cheacked on my boost gauge and had a flirt around the net it seems to be 0.6 to 0.9 ???? mine is boosting around 0.6 on the gauge ( hks ) but like i say runs very sweet and is as tight as can be with no rattles or knocks. It uses no oil or water at all its only got 69000 on the clock so all is well i hope !!

 

Nope something wrong if its only at .5 bar, thats limp mode, it should be pushing nearer .9 bar.
Still you have not said what model or year the car is?

Tony

 

its a 1995 wrx import.

 

saloon or wagon?

Tony

 

saloon. my gauge goes into red a 0.9 till 1.5 it is a greedy gauge not hks like i said When it went to the clinic they said it was all ok and it read 0.5 then?? Do they all read in bar?

 

You get ones that read PSI and Bar but mainly Bar, and .5 isnt right, it should be pushing .9 bar as standard, a run on a decent rolling road or resetting your ecu may clear the problem for now (it may become more apparent if you see your boost go up then go back to limp mode) or you could have another underlying issue that needs to be investigated, but its definately not right

As for the model/year, always best giving as much info as possible, here is to demonstrate why as your car is an MY95 wrx saloon producing 260ps (257bhp on super unleaded only) the wrx wagon produces 220ps (218bhp on super only), an MY94 wrx saloon produces 240ps (237bhp) and an MY97 wrx saloon produces 280ps (276bhp) so lots of different varients

cheers for the info will look into it asap
