Hi all....

I bought a modified wrx with a turbo 2000 engine in purple maf,yellow injectors,8s ecu,fmic,Vf 22, here's what work I carried out.

Head gaskets
Silicone inlet
Water temp sensor
Timing belt kit
Full service

I dropped the engine back in today plumbed everything in and it started after the first few cranks and was running fine until it got upto temperature and it was popping and detting I was having to hold the accelerator to the floor for the revs to climb like it was being starved of fuel although it smells really rich ?

It run fine before I took it out apart from the cooling system pressurising and the odd fuel cut here and there which is because of an mbc which will be coming off soon .

I'm stuck don't know what to try next feel like throwing in the towel any advice or local help would be greatly appreciated

Massive air leak or faulty MAF. Do a code read first.

What car do you have? year, model, etc.
Could you have set the timing wrong?

I'm going to buy a code reader tonight can you recommend any ?

Another thing I noticed is the turbo seems to be getting too hot and the coolant is boiling in the pipe from the header tank to the turbo although it isn't blocked as when I put water through the pipe it circulates back to the header...

It's a 93 wrx with a uk engine as it is running an 8s ecu and purple maf....

What's the best method for checking the timing ?

Cheers Matt.

When you fitted the belt as long as all the marks on the cams lined up with the marks on the belt you should be fine. Did you check that it didn't jump a tooth after installation of the belt because sometimes it can move if the slack isn't all taken up.

Its hard to explain without the pictures from the service manual....

If that 8s Jecs ECU is standard and not ELS'd and mapped then it can't handle those mods especially the yellow injectors, You running an after market zorst and induction kit as well as the FMIC.

Yep that's the ecu I have and it's also got a piper cross cone filter and twin pipes ninja back boxes to be honest I havnt a clue what is standard at what isn't so I'm guessing the next step is to remove as much aftermarket parts and replace with standard glad it was cheap I was after a project but this is proving to be a pain....

An 8s ecu would point to it being a v3/4 possibility so late 96-early 98. So you cant fit that ecu to a 93 car.

With those mods it won't run right, but should run better than you describe. Hard to tell what's wrong from here though.

As said read codes first.Join wires up under dash and count engine light flashes. Internet search for moreImore info and code lists.

Bop bop bang

It must have had a uk engine fitted with all the ecu and harness then....

Any idea why my turbo would be boiling water in the pipe to the header tank ?

Going to get the codes of it tmoz and go from there...

Cheers matt

I would suspect you have more then one specific problem with this one. Would be worth paying an expert an hours labour to go through it all.

If the coil pack is in the center front of the inlet then it's a Version 3/4 engine and the 8s is the right ECU. If that's the case the car will be massively overfueling with your mods. The 8S will handle an after market zorst, sports cat and panel filter. Injectors should be greys for the right fueling(usually cheap). Or speak to Simon at Jolly Green Monster about having a V4 8s ESL fitted and mapped to you current mods. You should be around 280-300bhp mapped fella.

Bop bop bang

Yeah it's got the central coil packs so its a v3/4....going to locate a set of standard injectors and standard air box and see where this gets me....

Would he be able to fit the esl and map it if I tell him my mods without taking my car ?

Cheers Matt

jason_2013

No a mapper will need to see the car. But phone him as a base map may be able to be loaded on to enable you to drive there.

Read the error codes. If its throwing an error code ifs unlikely to be a map issue but something not right.

Www.jollygreenmonster.com and in the help pages explains how to read the error codes

Cheers ! Just done the test and got 2 slow flashes followed by two fast flashes which indicates the knock sensor where do I go from here chaps ?

Cheers matt

Check knock sensor is plugging in under manifold.

If so try a replacement sensor.

I assume engine sounds normal?

Jolly Green Monster

Just reread first post.

Sounds likesomethings not fitted correctly

Bop bop bang

Cel light is now sorted I removed the knock sensor couldn't find anything wrong so refitted and that has solved that....

Car still running terrible when under load so off come the timing belt covers and it looks to be a tooth out so I'm going to refit the belt and that should give me a stable enough engine to start returning it back to standard....

Would black smoke also indicate a timing issue as getting a little bit when revved or would this be over fuelling ?

The engine seems to be getting too hot but stays ok on the gauge don't know if I'm just paranoid as it is circulating ok no blockages...

Cheers for all the advice guys ! Matt
