justarn 0 Posted July 4, 2011 Report Share Posted July 4, 2011 hey all, had a great day at santapod yesterday in my brown mk1 cab vr6 and decided to make a few engine changes heres a list of what i plan can anyone give me some pointers?im thinking75bhp nos with electronic controller ( will the clutch be up to the job?)uprated head gasket268 camsbest cheap obd2 intake manifold mod?gearbox final drive for better acceleration?c2 mapr888 tyresalready have airfilter and full exhaust.thanks.8-) Link to post Share on other sites
v_dubberoon 0 Posted July 4, 2011 Report Share Posted July 4, 2011 only my opinion but racelogic launch control seems the dogs dangleies fro shaving time off your 1/4 mile.....am sure the more knowledgeable will direct you in the best direction Link to post Share on other sites
J5KE F 0 Posted July 4, 2011 Report Share Posted July 4, 2011 888's are a must with ->20psiCams will improve responce, a decent map will smooth out ur power delivery especially in conjunction with cams, and exhaust.nos is cool and with a decent progressive controller set up correctly u should be fine on a standard box.(i ran 200 bhp direct port on my last mk3 turbo vr with stock box and internals)Also dont underestimate the improvements to be made from shedding a few unneccessary kilo's?!Look under your carpets for those few 100's of a second sand bags used for sound proofing!! They all add up!Finally probably one of the final mods would be to look at gearing, once u have ur car behaving how u plan a good 1/2-1 second can be reduced by minimising gear changes.. Come up to bug jam and say hi we'll all be there, qued up to run Link to post Share on other sites

J5KE F 0 Posted July 4, 2011 Report Share Posted July 4, 2011 Theres a fella called noel who runs a grey mk1 pickup with a 1.8t.. Hes in low 12's and potentially far more to come! Hell probably be at bug jam too! Link to post Share on other sites

justarn 0 Posted July 4, 2011 Author Report Share Posted July 4, 2011 jus checked, im not paid again until the last friday!-(ive read the vr can take big shots of nos, would 200bhp drect with the controller be ok on a stock engine? sounds scary!got an issue with the floor pan before i get carried away anyhow, the vr subframe is bending it upwards so i need to add some weight in metal and weld lol!also sometimes when i start her up i get a little backfire in the inlet, my last vr done that tho! is it a prob? ive read before its a design flaw in the manifold or is that b**lo*ks?

Dave Lea 4 Posted July 4, 2011 Report Share Posted July 4, 2011 i find solid engine mounts help for more instant power to the track Link to post Share on other sites
yakuza racer 16 Posted July 5, 2011 Report Share Posted July 5, 2011 gearbox- the G60 final drive will help alotpractice makes perfecton the street my mate would have me with his nissan turbo, but on the track it would be a very close race, all because i knew how to race on the track lol....

FishWick 21 Posted July 5, 2011 Report Share Posted July 5, 2011 also sometimes when i start her up i get a little backfire in the inlet' date=' my last vr done that tho! is it a prob? ive read before its a design flaw in the manifold or is that b**lo*ks?[/quote']Yeah it's bollards. Mine's backfired with 3 different designs of manifold :-) It's just the way they are. The little black plastic damper box attached to the idle valve doesn't like backfires very much. Blows it apart!

justarn 0 Posted July 5, 2011 Author Report Share Posted July 5, 2011 ah ok, its not a problem then... good, thanks kev.cheers yakuza, spoke to stealth today and the mk3 gti 16v has the same final drive at 3.6... they also told me it will make a massive difference, way more than cams!!! def my next mod lol. he also said 162 cams are the best? he said 168's do make the best peak power but 162's make more power everywhere exept at full bore making them way more usable, very useful info i think when everyone fits 168 and raves about em!

justarn 0 Posted July 5, 2011 Author Report Share Posted July 5, 2011 hey stig how did you strengthen your caddy floor? ive got convexed footwells ha! i was thinkin welding bars or 2inch lenghts of 5mm plate across the footwell inside. also maybe a length of plate spanning the jacking points and between the sub frame and footwell?now thinking 150bhp of nos for next years retro show! i reckon i could hit mid twelves then, my cabby is pretty stock airfilter and exhaust an i ran a 14.6 at 94 with a 2.1 60ft!

J5KE F 0 Posted July 5, 2011 Report Share Posted July 5, 2011 I only got a caddy van vrt and mk2 r32 t. noel is the dude with the mk1 caddy!The mk2 is running halex and caged so is pretty stiff! But with 600 lbs of torque its unknown if it will need more strength!Get sum pics up of ur project?? Link to post Share on other sites
justarn 0 Posted July 6, 2011 Author Report Share Posted July 6, 2011 mmmm mk2 r32t sounds good... 4wd? i just posted aload of pics in the photo section dude! Link to post Share on other sites

rm2was 0 Posted July 9, 2011 Report Share Posted July 9, 2011 Theres a fella called noel who runs a grey mk1 pickup with a 1.8t.. Hes in low 12's and potentially far more to come! Hell probably be at bug jam too!I'm pretty sure with a different driver that car ran 11.1 on it's first weekend out.And if you can stretch to a pair of proper slicks over R888s you will notice a massive difference! R888 are good as they are consistent, but they struggle to get up to temp quickly and are very stiff so break traction fairly easily. In my old car I ran 1.8 60fts on normal treads (launching on tick over too). James hodson runs 1.6 60fts on proper MH slicks!! Link to post Share on other sites
