Question: Next March I finish in the RAF after 22 years so am thinking of giving myself a well earned pat on the back by getting my engine rebuilt. The current spec is 104k miles showing 441 bhp on scoobyclinic rolling road on standard internals. I am currently running GEMS ECU mapped by steve simpson, APS 3.5 inch exhaust, FP green turbo, Aeromotive FPR, purple injectors, MRT FMIC bought 2003,APS parallel fuel rails, APS aluminium intake pipe with induction kit (not in wig or boxed), uprated pump (2nd upgrade) and intake manifold insulators. I am in two minds about where to go next either a 2.1 or a 2.35 rebuild. My thoughts are run about 500 bhp but ensure that the engine is safe to higher by using APR (?) head stud kit either 12mm or going upto 14mm with required engineering. What are your thought? I do plan a long time in advance and do ask a lot of questions. It took 3 months whilst down the Falklands to decide on the first tuning package I went for so I am starting this earlier as the cost will be higher. Thanks Steve
Answer: Hi Steve. Good for you mate! I like a chap who isn't afraid to enjoy himself. Pound for pound, we'd say the 2.1 stroker offers the best deal. We can use your original block for a safe 500 bhp, or fit a closed deck block if you like the belt and braces approach. We would use a nitrided crank, Cosworth pistons, K1 rods and ACL Race bearings. We could use the Cosworth 11mm 260,000lb head studs, which are very capable at that level. We'd also use Cosworth head gaskets and sump baffle, with an RCM oil pump. Turbo wise, we have a couple of choices from the Scoobyclimic range, or even a new entrant from Turbo Technics in the 500 bhp area. Are you seeking a full drive in drive out package?

Question: hi alan, bought a 03 sti off your brother a few weeks back(great car )its been remapped by martin to 310bhp:before i owned the car , have put a kn panel filter on which seems to have made a big difference. it has a prodrive back box and was looking at changing the down pipe to a sports cat type,would i notice much difference, as i dont want the hassle of doing away with cat and changing it each time for mot,also how much for remap if its been done before? cheers alan hope to see you soon
Answer: We can supply a 100 cell sport cat for 252 inc vat, fitting 60 inc vat. It would benefit from a map tweak at 144 inc vat, and we'd expect to arrive at around 340 BHP!

Question: hi alan my xr3i has had a new cam and followers fitted but it is still has a bit of a rattle,i noticed that the rocker arms move from side to side when the follower is fully down do you know if this is right if not any idea how to fix it, many thank,s colin.
Answer: Other than replacing them, not much really. They always were a bit sloppy. It is possible for these to suffer from low oil pressure at the head end, which can cause slack lifters. It's caused by the build up of deposits in the sump blocking the pick up pipe. If that happens, they are usually pretty noisy!

Question: Hi Alan, I have a 1996 honda civic vti, with an aftermarket intake and exhaust manifold and is now running lean, with flatspots and juddering in the lower rev range. My mechanic suggested a remap, what can you offer me to sort this problem out and what sort of price would i be looking at? cheers, ben
Answer: Hi Ben - We can't directly map that car. You may have a fault, as the manifold change wouldn't automatically cause a lean mixture. We can check it out for you of course.

Question: Hi Alan, i have recently got hold of a 2003 wrx and have seen that the car has a high flow downpipe and cat back system fitted. what i am wondering is has this been mapped or is there a way of telling? many thanks adam
Answer: Hi Adam - short of asking the previous owner, I'd say the best bet is a dyno test. It would give you power, torque, boost and mixture levels, enough to say yes it's good, or no, it isn't! Plus I'd expect to find someone there who can plug in, and see what's what.
