first hand experience of building a single

Recommended Posts

i thought i would write this as many of you starters out there are wanting to get big power by going single and probably dont know where to start.

 

i am not going to mention names on here as not to cause heated discussions but here is a list of everything i can think of that i have bought so far to get my car into the realms of 520-600 rwhp. ( not yet done as ryan is going to map it later this month). all i can say is that all of my stuff has come from boostlogic in usa and these guys are fast on delivery, pack the items very very well, and as usual for america give unfaulted customer services. they are more than happy to tell you what you don't need rather than giving you the sales speech on why you need this extra and that. as i say this is the basics that you need for a proper job.

 

 

1. check engine compression when warm, all my cylinders where measuring 152-160 psi.

 

2. check gearbox if auto and consider boostlogic upgrade or upgraded auto in general. (mines an auto) soon to be boostlogic.

3. check all the transmission and really all the common sense parts that will be taking the extra hammer with more bhp.

4. i replaced the inlet manifold gaskets (all three of them) @£20 from toyota.

5. fitted uk brakes and new slotted rotars front and back, with carbon pads.

6.fitted new braided brake lines to calipers

7. new dot 5 fluid

8. took body kit off and front and back bumper and rear spoiler.

9. replaced boot gas shocks (boostlogic)not really relavent.

10. fitted boostlogic fuel kit 780cc injectors(top feed low impedence soldered new wires on), fuel rail twin feed, aem fpr. twin walbro pumps with dedicated 30amp twin feeds.

11. fitted second fuel line (braided), 1 stock and one aem fuel filter.

12. fitted 2 volt meters (60mm gauges) on dash wired to terminals on pumps to get accurate readings off each pump(know when to shut pumps down if voltage drops for some reason)

13. fitted hks back box 4 inch and back pipe 4". 3" downpipe v band flange to 3" mid pipe 2 bolt flange.

14. cermic wrap from japan to wrap around downpipe and manifold

15. boostlogic manifold with 50mm wastgate 4 bolt flange , with v band adaptor so i could fit tial 44m wastgate. (order the v band flange manifold and put tial straight on. i tried mounting 56mm greddy ch wastegate but would not fit) this is why i had to do it this way.

16. t67dbb with boostlogic water jacket (watercooled) .81 ar (the bigger of the 2 (hoping to get more bhp with bigger ar but make up for lag with dbb) we will see next week!

17. turbo jacket

18. 4 inch induction pipe to aem cone filter

19. 2.5 inch inch ic pipe through front wing with 45degree silcone bend to 2.5 inch alloy 90 degree bend. with 2.5 inch coupler to 2.75 inch out. which then fits onto hks ic pipework leading to fmic.

20. hks big f*ck off bov valve, flange welded to ic pipe behind bumper next to ic drivers side.

21. hks big fmic

22. massive 3/4inch band hose clips with 13mm bolts (probably over kill but these babys wont be popping off again)

23. autobox cooler mounted below front drivers headlight in front of front wheel. (loads of space in there when expansion tank removed)removed stock lines and replaced with hose from auto box to cooler with an- fittings

24. allloy expansion tank fitted behind passenger side headlight

25. hks grounding kit ( a big bunch of 8 awg wires)

26. new toyota radiator and fan.

27. greddy relocation oil kit.

28. greddy oil temp and water temp block

29. boostlogic oil feed and oil drain for t67

30. fitted resistor pack

31. fitted hks dli for nice fat spark through aem

32. fitted defi boost gauge from turbo housing

33. fitted boost gauge from inlet manifold( just to check for boost leaks)

34. fitted vacuum gauge from inlet manifold

35. fitted oil pressure, oil temp, water temp gauges.

36. fitted aem afr gauge and aem ems

37. fitted aem wideband sensor in downpipe and wired into gauge.

38. new trd oil filter

39. changed oil 10/30 semi

40. hks cams

41. hks gaskets on block

42. removed all vacuum cra* including pressure tank, charcoal canister etc.

43. fitted front and rear strut bar

44. hks pro coilovers

45. breather k & n filters for inlet and cam cover

46. new cam belt

47. a full respray (not relevant)

48. new 275/35/18 rears and 235/245/40/18 fronts (not decided yet)

 

 

from this you should be able to work out all the suff you need and price it up and then sit down!

i wil be adding pictures of the conversion over the next few weeks.

There are a couple of ways of doing it, but mostly go single feed from each cam cover to a catch can, fill it with something that will 'catch' the vapours like wire scour e.t.c then a pipe to the intake pipe, that gives you a system very similar to stock

 

You can either use rubber pipes with banjo clamps, or AN/NPT type fittings and braided lines

 

Check Supradibbs engine bay

 

Rubber and Banjo clamps are cheap but functional, the braided lines and fittings will set you back around 200 to 300quid especially if you buy them from earls

Not sure why this is in tech, care to explain?

 

Much of what you have listed is not needed for a single conversion, details of which have been posted in great detail before. However it is a nice specification for a mid range conversion, but prefer not to mark the specs down as 'the gospel' of what is needed - it's not.

 

Is this a project thread with your own personal preferences for the conversion? If it is, I'd prefer you edited your post so we can move it to the project section :)

put it where you think best, it was aimed at helping people who like me didn't know where to start. i would have thought that this is bare minimum spec to reach over the 500rwhp from everybody i have talked to . maybe i am mistaken. as i said i will be adding pics later. you mention that this has been done loads of times before, but in all honesty i have struggled to find everything i needed on this site (pics and detailed descriptions for some of the installs). i find as a beginner the technical lingo is quite hard to understand at first. maybe there should be an "idiots guide" without taking the p*ss as a lot of beginners even when they start to read the posts don't fully understand them. boostlogic have a single conversion link on their website but they have still missed loads of stuff off. i have found over the last 4 weeks that there are all sorts of little problems that you come across when doing the install. if you can point me to a part of this site that has the full start to finish install with all the electrics, pinouts, explanations etc, that would be great. maybe i have missed something.

good spec matt.... like you i am a beginner, a quick search on the forum and a first look at the FAQ resulted in a wealth of information already available.

 

the more the merrier is what i say; however to suggest that the info wasnt present would be completely unfair.
