hi guys im planning on converting my supra over to a single turbo and ditching the twin set up so far i have

hks frontmount

hks filter

hks superdragger exaust cat back

uprated alloy rad

 

i know i will need a different manifold and down pipe a decat pipe

uprated fuel pump (i dont know if its uprated already how can i tell with out removing it?)

uprated plugs not sure on grade?

a remap or different ecu (suggestions?)

new turbo possibly some for of holset but suggestions? needs to spool fast and provide good power up to 500-550bhp

most probably going to need injectors (what size)

and boost controler

external wastegate

 

 

is there anything else?

where can i get the bits i need (mostly 2nd hand)

also what brands are best to go for and work best on the supra

 

also when i do my manual gearbox conversion whats the exact list of parts i need

 

the plan is to collect and build up parts (mostly second hand) and then either build it myself and get it mapped somwhere or take it to someone (depenant on spare cash)

You will learn loads if you take the time to read through some of them

 

This.

 

Also, if you say that you can't be bothered to read through then information that's already here - why should the Club Members be bothered to write the replies? As MagicTorch said, you'll get a LOT of information from the Project threads.

For 500-550hp id go for a GT35R turbo or ever a Borg Warner equivilant. Drop Paul Whiffin a P.M I'm sure he can do you a good deal on a full turbo kit with everything you need turbo side. For 500hp the stock fuel lines will be fine but you will need an updated pump. Although a Walbro pump will be Sufficient for this power it will be maxed out so I'd go for a Bosch 044 pump.

800cc drop it injectors will be ample for your setup too.

ECU side personally I'd go for a standalone ECU but the cost a lot but well worth the money.

yer iv been looking the last few weeks but its not really specific to what im trying to find out dont fancy spending hours a day reading through project threats to find out none of its relevent

 

In that case pick up the phone and speak to a tuning specialist, you can start with the ones on here.

100% agree with this mate GT35R is a very fast spooling turbo and will give u 500-550hp and make it a fun street car.

Missed where you said 550bhp, my best advice is buy a complete turbokit with everything you need, buying bits from all over the place can be a pita when it comes to fitting.

 

I would go with whifbitz 600bhp S362 62mm Borg Warner kit with 3" DP/MP £3396.35 + VAT

 

single walbro pump, drop in 650cc injectors

 

Syvecs ECU mapped by Ryan at 2bartuning

 

Decent single plate clutch if manual.

thanks guys thing is i have read a few of the project threads but none of them are what i want to do

 

i want to find as many parts as i can second hand the best parts for the least amount of cash

 

no point in phoning and bothering a company when i will probably do the work myself in my workshop really i should imagine there far to busy for that

 

so 044 best pump to go for and a gt35r well theres the first bits i need :)

 

never seen a pt 6262 or even heard of it will look that out too
