Hiya

This is a little formal intro for me and my ongoing project. I joined the forum a while ago, and you may have seen a few of my posts dotted about, but i thought I'd properly show you all my bab and our story so far, enjoy....

Well, she started life as a 1988 Jet Black. In the end of October '04 she was bought for the grand sum of £950 with 40,000 odd miles on the 998, from a lad in Essex To be fair tho - i do think it was his missus' car, as it was fairly standard and he had his own (very nice) 1380.

Anyhoo, when i got the car it had already lost most traces of being a JetBlack. It had white cooper stripes, a pinstripe and a chrome grill *mmmm shiny* First thing i did was add angel eye headlights and 4 angel eye spots, the clear rear lenses, and a stage1 kit.



Then over christmas i got and fitted some posepacks and luverly white centre 12x6 minilights





Passed my test Feb '05 and 4 weeks later stacked it in the back of a golf

[JetBLICK]

After lots of arguments and shouting with the insurance company, finaly got it repaired for a very very reasonable £500, which i wasn't too bothered about because the front was rotting away anyway.
When i got it back i decided not to put the stripes back on, as i thought it looked better without We had lots of fun that summer, we road trip'd to nuki and she behaved all the way there and back (6 hr round trip)



Then off to uni that year, and she must have got pissed off from me neglecting her, because come christmas hol's she was a bi@tch! Kept going wrong, and when i finally fixed her got her running sweet as a nut, on new years eve, she decided that life wasn't worth living and sent me into the middle of an island and up onto a sign post. Later we found out there was a crash on the same roundabout earlier in the day and oil was left in the road *tut tut* Unfortunatly the roundabout lies on the boundery inbetween worcestershire and gloucestershire, and neither council will own up and because we had no good evidence, there was nowt we could do



And to this day that post i bent still hasn't been fixed....

Anyhoo, enough rambling, this is where the fun starts properly :D:D.....

Me Dad's house don't have a garage, whereas before i could take the car to his and he would help me, from here on it was me on my own. My first obstical was trying to convince mother dearest to let me take over our garage, after trying various methods i found that this was a situation that could only be resolved by starting work whist she was out

Car went straight up on axle stands and took all the wheels off - thus making it impossible for mother dearest to move the car



Front off... ...i like angle grinders



Engine out and strip'd



SMB Kevlar front end, CF bonnet and CF boot





Then got myself some of those fancy flip front brackets from the US of A



They where a pain in the arse to fit, but we got there eventually





Then various accessories where offered up so the positioning, holes and bracketry could be drilled etc... before the bodyshop.

Then the car went off to paint, whilst it was there i sorted the engine out



Cleaned a little, before spliting it up (as you can see we have a very tidy garage)



Comparing a 3.1 and the 4.1



Had the fly lightened



Fitted a kent 286 cam and duplex timing gear - also pocketed the block with my trusty dremel



Recon'd the head with double valve springs



Then put it all together with the carbs after a good clean and fresh paint



Heres a little vid of it running in the garage - he he

[JetBLICK]

Finally the got the body back, all rot repaired and fresh coat of paint





Then just had to put it all back together - shiny bits first of course



Engine...



Recon'd some metty turbo vented calipers, with new pistons and seals







...wiring...



Then a few other boring bits, windows, brakes, seats...

...Then went on the first drive...



... at first we only got to about 5500 rpm, which i was a bit dissapointed about, but after I got an MOT and got a few miles on the motor she started to loosen up nicely and got to 8000rpm I decided that i couldn't be arsed to run the motor in properly because; A - i hadnt changed any bearings and the pistons had not been disturbed, the pockets wer done with them n place and B - by this time i only had a week left of sunner holiday to enjoy the car before i went back to uni, so i did just that.

[JetBLICK]

So, heres what it looked like when it was finished...











and on the first night i took it out, all the mini's where out and with fresh, un-polished paint we decided to go rallying

Before...








After...


The morning after... (doesn't look as bad in the photos)







t'was fun, but got a little dirty and i really must block all the holes in the bulkhead, water has a habit of coming through the holes where the fresh air vents once were

[JetBLICK]

in the next two months lots happened....

I fitted a swanky toad alarm

I got a new zorst, which i thought would be quieter, as it came with a centre silencer...



...it wasn't, it was for a big bore, so was very much louder, and i lost back pressure and lost 500rpm at the top of the rev range But it looked dead sexy!!!

Then the engine started bogging and making funny noises, after trying lots, i decided the solution would be to time the cam properly, 4deg should do it? right?

... it did, stoped bogging, but as a consiquence the exhaust valve on 4 was smacking the pistion, only i didn't realise till it went bang on the way to malvern show resulting in engine out again,



piston missing????



this is the remains of the piston which was found in the gearbox



Theres a lesson here ladies and gentlemen, when you hear a noise coming from your bodged engine, don't assume its the tappets



So, that my story so far. I like reading other peoples project threads on here, so i hope you've like seeing mine New things to do over christmas:

-Fit new 998 block with GT close ratio box, 12g940 head again, re-use 4.1 FD, re-use 286 cam - but check the timing properly.

-Fit all the suspension parts i've aquired (dampers, hi-los, new everything - the works!)

-Sort the interior properly

-Wide grp2 arches

-AND RALLY *woman of ill repute* THE BEAST!!!!



Nite all,

Dan

[Bungle]

looks good

i do like your bonnet hinges

[lew]

looks good , prob se you at the worcester meets soon ,

[miniman86]

well done mate lovely looking motor!!!!

[JetBLICK]

Yay!!! I got my beasty back on the road!!!! Ok... but first i must say, people of an mechanically opinionated nature should look no futher at this project. I'm a student - so im on a budget i'm also impacient - so i dont like waiting for other people to do things if it looks too simple and frankly although idealy i'd have liked my last motor to last a bit longer (2 months lol) - i'm not too fussed, this engine has only gotta last a yr or so till i've built my 1071 dream motor Plus the fact you can pick up 998's for free, so sod it..... here goes...

How to build a fast 998 engine in you're garage with help from a big hammer and a dremel


Firstly i got a GT box off a mate £35 - BARGAIN

I split and rebuilt it with hardened baulk rings (and gave it a bloody good clean!!) The reason for the GT box was for the close ratios, and because it was off a mate, i couldnt resist Also re-fitted the 4.1 final drive





Next i stripped down my spare block, this time including taking out the pistons+rods, and the crank. Then set to work with the good ol' dremel, cutting some beautiful pockects - okay, so i may have slipped a tiny bit - but it's nothing bad (no really trust me - its fine ) Then i re-fitted the crank with new bearings, and then the pistons went back in after scraping a large proportion of the carbon off the top of them with a stanley blade the pistons went in with the original rings, and after measuring with a feeler guage they are perfectly fine - so don't diss (if they wernt broke, dont fix em ) The con-rods went back on the crank with new bearings too









The two where put together and the lightened fly went back on with my new rally clutch As did the 286cam, but this time with 2deg offset key, as i think it was because i used a 4 last time and thats why the exhaust valve got friendly with the piston I did time it properly - to 106deg, but i think its probly something to do with the fact that its a 998 that its not the same timing as a 1275. by the way - too all the people that say dont bother with the tensioner on a duplex - i measured the degree of slack in mine - and its possible to be out by 5deg!!! so i'm sticking with it on!!







Then the head was taken apart and new valves where used for chamber 4, the rest where all just re-seated, for peace of mind.



Poped it all back in and all was go go



The new motor feels great!! I cut the pockets a bit deeper this time, and i also took more time making sure there is no way on earth they are near the valves. The gearbox feels great and really tight and direct with the new baulk rings, and the closer ratio works soo much better with the cam and the final drive. The cam itself isn't too bad to be fair, with the slightly different timing. Its better than it was at 0deg offset, but still fairly punchy like it was at 4deg, so im happy The best bit though is the rally clutch. A normal vetro clutch has springs to dampen the force - this plate doesnt!! Its nearly impossible to slip, and it disengages rite (and i mean it) at the top of the pedal. I've had to move the clutch stop futher up because i kept pushing the pedal down to where i used to, and then side stepping it, not ideal way to treat the new plate. So bringin the stop up higher means im not letting the plate slam together as ferociously....

.... all is good in my world now! , next job is to fit all the suspension and geometry kit thats sitting in my room and get to a RR to find out how much power this little beaut' is putting out

[Bungle]

did you have to skim the head for the compression raito difference between a 998 head and 1275 ?

[JetBLICK]

naa its an A+ 998 so its got flat top pistons, with a 12g940 head, so in theory the CR should have gone up to 10.5, which is acctually ideal for the high lift cam

[winter]

the front end is great! lovin the rally look mate

[biggav]

Christ, If only i didn't have a wife and 3 kids..... 2 jobs.... no garage.... and health problems!!!!!!

Flip front is ace!!!!

Might have to start work on a spare engine in the living room!!!!!
