mikeyb10supra Posted August 7, 2009 Share Posted August 7, 2009 take a look in Jamies garage. That will give you some idea of a well setup single conversion Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 7, 2009 Share Posted August 7, 2009 A lot of money initially, a lot for ongoing dramas and mantenance, and a good dose of luck. If you blanche at 10K don't even consider it, unless the car will cover tiny mileages and you don't mind constant fiddling. If you have an N/A just buy two nice TT's and have change, for the same money as doing a proper conversion on yours Quote Link to comment Share on other sites More sharing options...
caseys Posted August 7, 2009 Share Posted August 7, 2009 Money - as CW said circa £10k Patience. Determination. Knowing that you shouldn't attempt to do things on the cheap. Knowing that it's not just the single turbo parts you should look at - check what condition your engine is in compression wise, get the head checked too. You can get away with a stock block and head if they're in good condition and you're not going for mega boost or expect standard NA/TT reliability. Then again look at Mr 2.0 bar on here. His stock engine is doing just fine and he has no mechanical sympathy whatsoever from the videos I've seen I'd agree to look at the link Homer posted up, pay attention to the big posts from Michel Lane, Alex, Ian C. I think it comes down to two points in my humble opinion : Do you have £10k odd you can spend on the car If it goes wrong (Don't believe it won't some day), can you afford above that £10k any contingency cash to spend on the unexpected/unaccounted for. If you don't have the cash sell your car and buy a single that's been done properly if it's within your budget. If you don't really, please, don't consider it. It'll just be too much hassle and stress for you. Quote Link to comment Share on other sites More sharing options...
pistonbroke Posted August 7, 2009 Share Posted August 7, 2009 Are you BPU yet,? maybe you should consider this as a first port of call if you aren't. You can fully BPU a TT for about 1K, you'll get a reliable 400hp ish, which may not sound like a mahoosive increase, but believe me, it transforms the car.

MarkR Posted August 7, 2009 Share Posted August 7, 2009 Sell yours and buy a single already done. I'm busy doing mine, see link in my signature. 10k is easily done, and then some after all the labour. Then if you fancy changing the turbo or a few small things it won't cost the earth.

j_jza80 Posted August 7, 2009 Share Posted August 7, 2009 Caseys post says it all, especially the part about establishing the engines health. The first thing I would do id have the compression tested, so that you know wether to budget for a rebuild too. Don't forget about supporting parts (IE Uk spec brakes at least, LSD, decent suspension setup etc) If your car is an auto, i'd budget for a manual conversion and clutch too while you're at it for reliabilitys sake.

Luxluc Posted August 7, 2009 Share Posted August 7, 2009 My single conversion was approx 11 k and I still have parts that have to be done (am looking for a rad upgrade, oil cooler kit, ...). If you wanna go the safe route, I think 10k is not enough (unless you plan to fit everything yourself and safe some labour). Luc Quote Link to comment Share on other sites More sharing options...
SupraAyf Posted August 7, 2009 Share Posted August 7, 2009 Why don't you just save your money and buy a nice, ready built single from Japan. If done through the right sources you should find a lovely car at a much reduced cost. .................so I took the easy option; so what!!

L33 Posted August 7, 2009 Share Posted August 7, 2009 expensive option, full rebuild and single conversion for me has already hit 15k before labour! Quote Link to comment Share on other sites More sharing options...
caseys Posted August 7, 2009 Share Posted August 7, 2009 (edited) I forgot... Higher general running costs from then on. Be prepared for a shorter service period and a more costly service period i.e better grade plugs, oil etc. Also you'll have to be spending money on good quality tires when you need new ones as well as the brakes/pads. If you want the power you need to spend the money in a) putting it down through the road with good traction, b) being able to stop quicker than your usual braking distances as you'll be hitting where you normally brake at a higher speed possibly. Seriously the cheap kits are cheap for a reason. Buy cheap, buy twice for most things. As an example then as I need a break from work, these are the most vital bits imho: Engine Healthcheck - compression test & thorough ramp / fluid inspection £300-500 Turbo - £950-1500 External wastegate £250-500 Intake + air filter £100 Manifold £1000 Downpipe/midpip £500+ Decat £100 Turbo Oil drain kit £100 Turbo oil feed kit £50 Turbo water lines - braided hoses + earls - £80 Fuel Pressure regulator + fitting kit £200 Fuel Pressure gauge £20 650CC injectors £660 550CC UK spec injectors 2nd hand £100-150 Fuel pump + fittings £175 (Bosch) 3-4' Exhaust - £350-400+ Intercooler + hardpiping + fittings £1000 Intake plenum (optional) £700 New radiator (if req) £350-500 New clutch (if manual) £500+ Oil cooling (if auto) £200+ Standalone ECU (if manual) inc DLI/MAP sensor £1200-1500 Piggyback ECU (if auto) £400+ Mapping £400+ Boost Controller £250 AFR sensor + gauge £250-300 Boost Gauge £70 Full service after all this - filters, plugs, oil, coolant £200 Budget for misc things like fitting issues, gaskets, fittings £500+ Total cost if buying new bits manual excluding rad or intake £8800+ Total cost if buying old bits manual excluding rad or intake £8000 if you find a 2nd hand ECU Total cost if buying new bits auto excluding rad or intake £7500 Total cost if buying old bits auto excluding rad or intake £7000 That's with going with the lower-end estimates on Turbo, injectors, exhaust choices that are out there. It's also assuming you'll fit everything yourself and the only thing you won't do is the mapping. Talking about a small 68/70/82 AR trim turbo and circa 500-550BHP. If not add on a fair few days labour at a decent garage @ £70+/hour. Yes lower the price if you buy everything in a kit from a good retailer and use branded/known quality products, as they'll be getting all the business and so can trim prices possibly. You're a bit stuffed at the moment for parts from Japan or the US, due to the exchange rate but the $:£ rate is the best it's been for 10 months now @ $1.70/£1. Of course shipping from the states expect a hefty shipping and of course get in your best dog show pose for Customs & Excise charges. Prices are what I can grab and some people I am sure will correct me on bits/prices here, I've probably missed a few bits too not thinking. Those are the vitals covered. Things you should consider to make it worthwhile/improve it's reliability: Oil Temp, Oil Pressure, Water Temp, EGT Gauges @ £100+ each for decent ones Decent tires (T1R, GYF1 GSD3s, R888s) - £800-1000 Full Geo setup £400 UK spec brakes Front/rear / D2 calipers - £1200ish New disks £150 New pads brembo/hawk/CW £120 Goodrich braided hoses £65 Motul 5.1 £25 New shocks £500+ Head rebuild £2000ish Oil Pump £100ish Water Pump £? Cam Belt £50 Aux Belt £80 Crank Pulley £200 Aux pre-tensioner Pulley £120 Front main crank oil seal Rear main seal Cam Seals Head Gasket kit ARP stud kit Rods, Pistons, Crank, bottom end rebuild etc... Anyone please quote/edit this list and change prices/add bits for OP's guidance I am not an expert on this, many have done more detailed single conversions and it would pay to look in the Tech section at the Build/Project threads. I'm just approaching this from owning an NA then going to Single Ownership, understanding what had been spent on my car and replacing/remediating what I've needed to and what I am going to do in the future. I have not done a single build from scratch but did look around about 3 years ago when I had my NA how I wanted it and nothing down the NA route appealed to me anymore. Nothing on my list is to make it look nice, this is purely from an engineering point of view, reliability/quality first in my book, make it look nice when you have nothing left to improve mechanically. I'm hoping you take peoples advice here to heart and plan well, they're not out to water down your cornflakes or ruin your plans, people give these figures for a reason - experience. I don't like it when my car has had issues in the past and it gets you down y'know? If you have a reliable NA/TT at the moment and are happy, don't move to a cheap conversion and get unreliability. It'll just get you down, make you not love your car any more and ruin the experience for you in general. If you've got the budget to do it well, go for it, it's a long road and a labour, but in the end if done properly it's worthwhile.

paul mac Posted August 7, 2009 Share Posted August 7, 2009 Ok guys please don't kill me for asking . What exactly do i need do a single turbo conversion ? I know i need up upgrade the fueling , injectors but im not sure what else. I've looked through threads on here so yes i've searched but i'm just confused as to what i need. Thinking of starting this after xmas im just a bit bored with the car and want more power . it really does depend on what kind of power you are going for, and i think your quite fortunate being a girlie you haven't got flamed for asking this question , seriously, you need to do some more research, look at members cars/garages and maybe get a ride in a single with the kind of power you are looking at, if you keep the power to around the 450-500 mark you can get away with keeping the budget well down and still have a car quicker than 95% of whats on the road, if budget is not an issue go for it. Granted i am in the middle of spending a lot more money on my car (this is choice not necesity) but have a look in my garage at its current spec which has been running without any major issues (touch wood ) for 4 years on a budget at least half of the figures i have read in this thread:taped:, the other thing you would need to do if you cant/dont have time, to do it yourself is find a reputable garage that is not going to do shoddy work or rip you off.
